A disturbing Inspector General report from the shows that medical errors are harming and killing our senior citizens at alarming rates.
An estimated 15,000 Medicare patients die each month, and many more are injured, because of usually preventable medical mistakes in hospitals and other facilities.
The report focused on “adverse events,” defined as “harm to a patient as a result of medical care, such as infection associated with use of a catheter,” and “never events,” which are specific “serious events, such as surgery on the wrong patient, that the National Quality Forum (NQF) deemed ‘should never occur in a health care setting.’”
The Inspector General of the Department of Health and Human Services found:
—An estimated 13.5 percent of hospitalized Medicare beneficiaries experienced adverse events during their hospital stays.
—An additional 13.5 percent of Medicare beneficiaries experienced events during their hospital stays that resulted in temporary harm.
—Physician reviewers determined that 44 percent of adverse and temporary harm events were clearly or likely preventable.
—Hospital care associated with adverse and temporary harm events cost Medicare an estimated $324 million in October 2008.
Significantly, the 2009 loss to taxpayers was “$4.4 billion spent on care associated with events”–which did not even include the cost of followup care.
The cost in lives, health, and taxpayer dollars of preventable medical errors is far too high. Respect for life of our senior citizens requires accountability when harm occurs, and preventive steps to ensure patient safety.

ADVERSE EVENTS IN HOSPITALS:
NATIONAL INCIDENCE AMONG MEDICARE BENEFICIARIES
Daniel R. Levinson
Inspector General
November 2010
OEI-06-09-00090
EXECUTIVE SUMMARY
OBJECTIVES
To estimate the national incidence of adverse events for hospitalized Medicare beneficiaries, assess the preventability of such events, and estimate associated costs to Medicare.
BACKGROUND
The term “adverse event” describes harm to a patient as a result of medical care, such as infection associated with use of a catheter. The term “never events” refers to a specific list of serious events, such as surgery on the wrong patient, that the National Quality Forum (NQF) deemed “should never occur in a health care setting.” The Tax Relief and Health Care Act of 2006 mandates that the Office of Inspector General report to Congress regarding the incidence of never events among Medicare beneficiaries, the payment for services in connection with such events, and the Centers for Medicare & Medicaid Services (CMS) processes to identify events and deny payment.
We selected a nationally representative random sample of 780 Medicare beneficiaries from all beneficiaries discharged during October 2008. Physician reviewers determined (1) whether an adverse event occurred, (2) whether the event was on the NQF list of Serious Reportable Events or the Medicare list of hospital-acquired conditions (HAC), (3) what the level of harm was to the patient, and (4) whether the event was preventable. To establish an estimated adverse event incidence rate, we included events on the NQF and the HAC lists and events resulting in the most serious harm as defined by a patient harm index (prolonged hospital stay, permanent harm, life-sustaining intervention, or death). We also determined the cost to Medicare for hospital care resulting from the events. Lastly, we identified additional events that resulted in temporary patient harm but were not comparable to the more serious events in our overall rate and assessed their preventability and cost.
FINDINGS
An estimated 13.5 percent of hospitalized Medicare beneficiaries experienced adverse events during their hospital stays. Of the nearly 1 million Medicare beneficiaries discharged from hospitals in October 2008, about 1 in 7 experienced an adverse event that met at least 1 of our criteria (13.5 percent). This rate projects to an estimated 134,000 Medicare beneficiaries experiencing at least 1 adverse event in hospitals during the 1-month study period. We calculated incidence rates for adverse events that met our three criteria: 0.6 percent of beneficiaries had an NQF Serious Reportable Event, 1.0 percent had a Medicare HAC event, and 13.1 percent experienced an adverse event resulting in the four most serious categories of patient harm. An estimated 1.5 percent of Medicare beneficiaries experienced an event that contributed to their deaths, which projects to 15,000 patients in a single month.
An additional 13.5 percent of Medicare beneficiaries experienced events during their hospital stays that resulted in temporary harm. Temporary harm events are those that require intervention but do not cause lasting harm. Although many cases represent fairly minor occurrences, such as hypoglycemia, others were classified as temporary harm only because the patients were in the hospital for lengthy periods as a result of other, more serious, diagnoses, allowing hospitals enough time to address the harm prior to discharge. Additionally, 28 percent of beneficiaries who experienced adverse events also had temporary harm events during the same stay.
Physician reviewers determined that 44 percent of adverse and temporary harm events were clearly or likely preventable.
Physicians determined that 44 percent of all events were preventable and 51 percent were not preventable. (For the remaining 5 percent of events, physicians were unable to make determinations.) Events related to surgery or procedures were less likely to be preventable than other types of events, such as hospital-acquired infections. Preventable events were linked most commonly to medical errors, substandard care, and lack of patient monitoring and assessment. Physician reviewers assessed events as not preventable when they occurred despite proper assessment and care or when the patients were highly susceptible to the events due to health status. Nearly all events on the NQF and Medicare lists were assessed as preventable, a key criterion of both lists.
Hospital care associated with adverse and temporary harm events cost Medicare an estimated $324 million in October 2008. Sixteen percent of sample beneficiaries in the Medicare Inpatient Prospective Payment System who experienced events incurred additional Medicare costs as a result. The added costs equate to an estimated 3.5 percent of Medicare’s expenditure for inpatient care during October 2008. To give these figures an annual context, 3.5 percent of the $137 billion Medicare inpatient expenditure for FY 2009 equates to $4.4 billion spent on care associated with events. Two-thirds of Medicare costs associated with events were the result of entire additional hospital stays necessitated by harm from the events. Additionally, these Medicare cost estimates do not include additional costs required for followup care after the sample hospitalizations.
RECOMMENDATIONS
As the Federal Government’s principal agency for protecting the health of Americans, the Department of Health & Human Services (HHS) is uniquely positioned to lead national efforts to reduce adverse events in hospitals. As part of a national strategy to improve health care quality mandated by the Patient Protection and Affordable Care Act (ACA), HHS is to identify areas that have the potential for improving health care quality. Because many adverse events we identified were preventable, our study confirms the need and opportunity for hospitals to significantly reduce the incidence of events. A number of agencies within HHS share responsibility for addressing this issue, most prominently the Agency for Healthcare Research and Quality (AHRQ) as a coordinating body for efforts to improve health care quality and CMS as an oversight entity and the Nation’s largest health care payer.
Therefore, we recommend the following:
AHRQ and CMS should broaden patient safety efforts to include all types of adverse events. This broader definition would apply to a number of activities, including setting priorities for research, establishing guidelines for hospital reporting, developing prevention strategies, measuring health care quality, and determining payment policies.
AHRQ and CMS should enhance efforts to identify adverse events. Identifying adverse events assists policymakers and researchers in directing resources to the areas of greatest need, setting clear goals for improvement, assessing the effectiveness of specific strategies, holding hospitals accountable, and gauging progress in reducing incidence.
AHRQ should sponsor periodic, ongoing measurement of the incidence of adverse events.
AHRQ should continue to encourage hospital participation with Patient Safety Organizations, entities intended to receive adverse event reports from hospitals, and forward the information to a national AHRQ database.
CMS should use Present on Admission Indicators in billing data to calculate the frequency of adverse events occurring within hospitals.
CMS should provide further incentives for hospitals to reduce the incidence of adverse events through its payment and oversight functions. The ACA makes several changes to the HAC policy, including allowing the Secretary of HHS to expand the list of HACs. The ACA gives the HAC policy greater significance by using the list of HACs to implement Medicare payment penalties, create performance measures, and prohibit Medicaid payments for associated care. The conditions of participation for Medicare and Medicaid require that hospitals have programs to demonstrate quality improvement where evidence shows practices can improve outcomes.
CMS should strengthen the Medicare HAC policy, such as by expanding the policy to include more events that harm beneficiaries.
CMS should look for opportunities to hold hospitals accountable for adoption of evidence-based practice guidelines.
AGENCY COMMENTS
We received comments on the draft report from AHRQ and CMS. AHRQ concurred with our recommendations, stating that adverse events affect hospital patients at an “alarming rate” and that it must continue working to improve patient safety. AHRQ stated that it intends to foster continued improvement in both identifying and reducing adverse events through operational programs, research efforts, and further collaboration with other agencies. CMS also concurred with our recommendations, stating that it is committed to the reduction of adverse events in hospitals and other health care settings and that although it has taken significant steps to address these issues, more work needs to be done. CMS stated that it will “aggressively pursue” broadening the scope and definition of patient safety efforts to be more inclusive of various types of adverse events and more closely monitor and address hospital quality of care. CMS also outlined several current and planned efforts to both create incentives and provide support for patient safety improvements by hospitals.
We made minor changes to the report based on technical comments. TABLE OF CONTENTS

INTRODUCTION
OBJECTIVES
To estimate the national incidence of adverse events for hospitalized Medicare beneficiaries, assess the preventability of such events, and estimate associated costs to Medicare.
BACKGROUND
Statutory Mandate and Office of Inspector General Response
The Tax Relief and Health Care Act of 2006 (the Act) requires that the Office of Inspector General (OIG) report to Congress regarding the incidence of “never events” among Medicare beneficiaries; the extent to which the Medicare program paid, denied payment, or recouped payment for services furnished in connection with such events; and the processes that the Centers for Medicare & Medicaid Services (CMS) uses to identify such events and deny or recoup payment.1 OIG is also to make recommendations for such legislation and administrative action as OIG determines is appropriate. (For relevant text of the Act, see Appendix A.) To meet the requirements of the Act, OIG released a series of reports beginning in 2008 and will publish additional reports based on ongoing work.2
Adverse Events in Hospitals
Following a review of Medicare policies and expenditures, as well as consultation with CMS and the Agency for Healthcare Research and Quality (AHRQ), we chose to focus our work on inpatient acute care hospitals. For fiscal year (FY) 2009, Medicare costs for inpatient care were $137 billion, constituting 28 percent of total expenditures.3 As a condition of participation in the Medicare and Medicaid programs, Federal regulations require that hospitals develop and maintain Quality Assessment and Performance Improvement (QAPI) Programs.4 As a

part of their QAPI programs, hospitals must “track medical errors and adverse patient events, analyze their causes, and implement preventive actions.”5 Federal regulations do not require specific program characteristics. The QAPI provisions also require that hospitals establish programs to demonstrate improvement in quality indicators for which there is evidence that practices will improve outcomes.6 As an additional quality effort, Quality Improvement Organizations (QIO) contract with CMS to assist hospitals in improving the quality of care for Medicare beneficiaries, including addressing patient safety issues.7
A variety of terms, lists, and definitions are used to identify health care events that result in patient harm. For purposes of the Act, the term “never event” means an event that is listed and endorsed as a serious reportable event by the National Quality Forum (NQF)8 as of November 16, 2006.9 The NQF uses the term “serious reportable events” to describe a specific list of events associated primarily with patient death or serious disability that are both egregious and preventable, concluding that they “should never occur in a health care setting.” These became known as “never events.” (For a list of NQF Serious Reportable Events, see Appendix B.) The NQF list is often used by patient advocates and health care payers in establishing patient safety policies.10 The health care community now uses the term “adverse event” more commonly than “never event” to refer to harm experienced by a patient as a result of medical care. After consulting with congressional committee staff in 2007, we expanded our approach to be consistent with patient safety research and industry trends.
As used in this study, an adverse event is defined as harm to a patient as a result of medical care or in a health care setting. Although an adverse event indicates that the care resulted in an undesirable clinical

outcome and may involve medical errors, adverse events do not always involve errors, negligence, or poor quality of care and are not always preventable.11 Research and policy to improve patient safety and reduce the incidence of adverse events often focus on identifying and addressing systemic problems that may lead to patient harm and avoid labeling the event as an outcome of negligence or poor quality. Additionally, researchers, policymakers, and health care entities sometimes adopt different standards for distinguishing between degrees of patient harm in determining whether they classify an occurrence as an adverse event. Thus, entities tracking events may find different results depending on the list used to identify and classify events.
The National Coordinating Council for Medication Errors Reporting and Prevention (NCC MERP) Index for Categorizing Errors can be used to classify adverse events by level of patient harm. The NCC MERP Index was initially developed to categorize the effect of medication errors and considers whether the occurrences had an effect on the patients and, if so, how harmful they were. The index includes categories for circumstances or occurrences that presented a risk but did not cause harm, often referred to as “near misses,” and those that caused harm. Table 1 shows the NCC MERP Index for Categorizing Errors.

Researchers have used the NCC MERP index for measuring and distinguishing other types of adverse events, rather than only medication errors. For example, the Institute for Healthcare Improvement (IHI), a nonprofit organization that advises hospitals regarding health care quality, uses a modified version of the NCC MERP index to measure the degree of patient harm, regardless of whether the harm was the result of an error. 12
Present on Admission Indicators and Medicare’s Hospital-Acquired Conditions Policy
Medicare reimbursement to acute care hospitals through the Inpatient Prospective Payment System (IPPS) is generally determined by grouping codes representing patient conditions into Diagnosis-Related Groups (DRG) based on the average cost of care for patients with similar conditions.13 Hospitals may submit Medicare claims under IPPS using nine diagnosis codes and six procedure codes for each hospital stay. Historically, if a Medicare beneficiary experienced an adverse event that resulted in assignment of a more costly DRG, CMS paid the higher DRG.14
Beginning October 1, 2007, hospitals are required to assign a Present on Admission (POA) Indicator to each principal and secondary diagnosis for acute IPPS claims for all discharges.15 This was an initial step in complying with the Deficit Reduction Act of 2005 (DRA), which required CMS to select at least two hospital-acquired conditions (HAC) for which hospitals would not be paid higher Medicare reimbursement.16

In response, CMS issued regulations outlining a policy to deny hospitals higher payment for hospital admissions complicated by any of 10 categories of HACs.17 The DRA required that the conditions meet the following criteria:
conditions that are high cost, high volume, or both;
conditions that, when present as a secondary diagnosis, result in assignment of a case to a DRG that has a higher payment;
conditions that could be reasonably prevented by using readily available evidence-based guidelines; and
conditions that are identifiable based on one or more unique diagnosis codes.18

etermining the Incidence of Adverse Events
R
esearch indicates that identifying adverse events retrospectively is a complex and difficult task, requiring extensive clinical knowledge, adequate documentation, and subjectivity on the part of the researcher.20 Medical records review is often considered the most definitive method for detecting adverse events because it can provide detail about both the adverse event and the circumstances, such as the patient’s condition prior to and following the event.21 However, medical records reviews can be costly, requiring hospital staff to make records available and substantial effort by physicians or other clinicians to review them. To limit physician medical records reviews required to identify adverse events, cases can be screened to identify potential

adverse events using other methods, such as nurse reviews of medical records and analysis of POA indicators in hospital claims data.
Nurse review of medical records. Medical records screening can identify potential adverse events based on information in the medical records. The IHI Global Trigger Tool (GTT) uses a review of medical records to identify “triggers” that could signal patient harm, thereby identifying potential adverse events. A trigger could be a description of the harm itself or a reference that indicates harm occurred (such as a return to surgery). The review is designed to be completed by nurse reviewers, with the results then confirmed or refuted by a physician. Barriers to medical records screening include incomplete records and high labor costs for review.
Analysis of POA indicators. Automated computer programs can review Medicare billing data, specifically the POA indicator codes assigned to each diagnosis, to identify conditions that developed during hospital stays and possibly constitute adverse events. Although these programs enable examination of large numbers of hospital stays, barriers exist to POA analysis, including inaccurate or incomplete data. CMS’s POA coding requirement began in October 2007, and the accuracy and completeness of hospital coding of POA indicators have not yet been validated. Additionally, conditions can be acquired in hospitals that are not related to medical care and therefore not adverse events.
OIG case study. Prior to this study, we conducted a case study of the incidence of adverse events occurring during October 2008 for a random sample of 278 Medicare beneficiaries’ hospital stays in 2 counties.22 We estimated that 15 percent of Medicare beneficiaries in the two counties experienced events meeting at least one of the following criteria: events on the NQF list of Serious Reportable Events; events on Medicare’s list of HACs; or events involving prolonged hospital stays, permanent harm, life-sustaining intervention, or death (classified as F-I level of harm on the NCC MERP index). An additional 15 percent of beneficiaries experienced events involving temporary harm (classified as E level of harm on the NCC MERP index). The case study served in part to test the usefulness of various methods for identifying adverse events. We found that, combined, nurse screening of medical records and analysis

I N T R O D U C T I O N
of POA indicator codes in billing data identified 94 percent of occurrences that physicians ultimately determined to be adverse or temporary harm events.23
Determining the Preventability of Adverse Events
To provide additional context regarding adverse events, some researchers have assessed whether adverse events were preventable and described the circumstances associated with events. A 2008 review of eight preventability studies found that the median percentage of adverse events judged preventable was 43.5 percent.24 Assessing preventability can provide greater understanding of the causes of adverse events, which can be used to develop actionable solutions to the systemic problems that lead to events. Also, preventability is a statutory criterion of Medicare’s nonpayment policy for HACs; CMS was required to select only conditions that can be “reasonably prevented by using readily available evidence-based guidelines.”25
Reducing the Incidence of Adverse Events
Reducing the incidence of adverse events in hospitals is a critical component of efforts to improve patient safety and quality care. The Institute of Medicine (IOM) report, To Err Is Human: Building a Safer Health System, focused widespread attention on the problem of adverse events. IOM cited two studies that used medical records reviews to identify adverse events and assess whether events were preventable. IOM concluded that preventable adverse events caused “at least 44,000 and perhaps as many as 98,000 deaths in hospitals each year” and outlined a national plan to address adverse events.26
As part of its plan, IOM recommended the creation of a nationwide system for the collection of standardized adverse event data by State governments. As reported by OIG, 25 States and the District of Columbia had adverse event reporting systems in 2008, 11 of which

used the NQF list of Serious Reportable Events or a modified version of the list to define what events are reportable.27 To date, no national adverse event reporting system exists and there are no Federal standards regarding State systems.
Following the IOM report, the Federal Government formed the Center for Quality Improvement and Patient Safety (CQuIPS) within AHRQ to provide national leadership in improving patient safety. In a 2009 report, AHRQ identified its core agency objectives for CQuIPS as developing a solid evidence base, designing useful tools for providers, and disseminating information for implementation.28 As mandated by Congress, AHRQ releases an annual report to the Nation about health care quality that is produced by CQuIPS and includes measures of patient safety.29 The National Healthcare Quality Report includes measures of the incidence of certain types of adverse events, using data from sources such as the Medicare Patient Safety Monitoring System (MPSMS), an AHRQ-CMS collaborative effort to identify adverse events through analyses of medical records and Medicare claims data for beneficiaries’ hospital stays.30 AHRQ is also responsible for implementation and oversight of the certification process for Patient Safety Organizations (PSO) created by the Patient Safety Act and Quality Improvement Act of 2005.31 PSOs are in the early stages of development, but are intended to receive adverse event reports from hospitals and forward the information to a national AHRQ database from which CQuIPS will analyze aggregated data. AHRQ developed a set of event definitions and reporting tools known as the Common Formats, which PSOs can choose to use and which contain data elements that AHRQ determined are important for a complete and

useful adverse event report.32 A variety of organizations are eligible to become PSOs, including hospital associations, hospital chains, and patient safety consulting groups.33 For a 2009 OIG study, staff from selected PSOs reported barriers that could limit hospital participation in PSOs and questioned the usefulness of submitting data for aggregation.34 Finally, the American Recovery and Reinvestment Act of 2009 appropriated $300 million to AHRQ to sponsor and disseminate research that compares the effectiveness of clinical care options, the purpose of which is to promote evidence-based medical care.35
In March 2010, Congress passed health care reform legislation in the form of the Patient Protection and Affordable Care Act (ACA).36 The ACA includes a number of provisions to take effect over multiple years, including expanded funding and authority to the Department of Health and Human Services (HHS) to address health care quality issues. Among the initial efforts to implement the ACA, the Secretary is to establish a national strategy for quality improvement in health care by January 1, 2011.37 The law requires that the strategy address eight national priority areas, one of which is to improve patient safety.38 It also increases funding to CQuIPS for research grants to explore best practices.39 Among its payment provisions, the ACA expands the Medicare HAC policy to mandate hospital payment penalties for high rates of HACs,40 create new quality measures,41 and require State Medicaid agencies to deny higher reimbursement for care associated with HACs.42

METHODOLOGY
Scope
This report estimates the national incidence of adverse events based on a representative sample of Medicare beneficiaries discharged from inpatient acute care hospitals during October 2008. Our results are projectable to all Medicare beneficiaries hospitalized during this period nationwide. To determine the estimated rate of adverse events, we used criteria developed by NQF, CMS, and NCC MERP. We included in the estimated national incidence rate all patient harm that occurred during the hospital stay, regardless of whether it was preventable. Also, the report provides a physician assessment of the extent to which identified events were preventable and analysis of billing data to estimate the cost to the Medicare program for increased reimbursement resulting from all events and preventable events.
Sample Selection
We selected a sample of Medicare beneficiaries from the National Claims History (NCH). Of the 999,645 beneficiaries discharged from acute care hospitals during October 2008, we selected a random sample of 785 beneficiaries. We excluded 5 beneficiaries as ineligible because the hospital was currently under OIG investigation, resulting in a sample of 780 beneficiaries. In July–October 2009, we requested and received medical records from hospitals regarding sample beneficiaries’ hospital stays. Fifty-four of the beneficiaries had more than 1 hospital stay during October (50 had 2 stays and 4 had 3 stays). Combined, sample beneficiaries had 838 hospital stays with discharges in October 2008 and an average length of stay of 5.2 days.43
Identifying Adverse Events and Determining Preventability
We conducted a two-stage review to identify adverse events experienced by each beneficiary. The first stage used three screening methods to identify cases likely to include an event. This enabled us to reduce the number of cases requiring the second-stage physician review. During the first stage, we identified cases that met one or more of the following conditions: (1) certified medical coders identified codes in the Medicare claims data that were listed as not present on admission, (2) nurse reviewers found evidence of a potential adverse event in the medical

records, or (3) the beneficiary had a hospital admission within 30 days after discharge for his or her last sample hospital stay ending in October 2008.44
We identified 420 cases for the second stage of review, which entailed a review of the full medical records by physicians to identify events. To ensure consistency across physician reviewers, we facilitated weekly conference calls during which all physician reviewers discussed cases that either were complex or had possible implications for other cases. We included events experienced by patients during hospital stays or during prior, contiguous outpatient visits (wherein patients were transferred directly from outpatient care to inpatient care within the same facility). For example, we included in our count an adverse event that occurred in a hospital emergency department immediately preceding admission to inpatient care. We did not include events that occurred prior to a beneficiary’s arrival on the hospital campus. When an initial event caused a series of related events for the same patient, we collapsed the events into a “cascade event,” which counted as a single event.45 For a glossary of selected clinical terms used to describe events, see Appendix D.
As part of the structured protocol, physician reviewers also determined the extent to which the identified events were preventable. Generally speaking, physicians assessed events as preventable when they determined that harm could have been avoided through improved assessments or alternative actions. Physicians assessed an event as not preventable when they determined that harm could not have been avoided given the complexity of the patient’s condition or the care required. The physician protocol used the following response scale for assessing the preventability of events: clearly preventable, likely preventable, clearly not preventable, likely not preventable, and unable to determine. Physicians used their clinical experience and judgment to make preventability determinations. They considered all evidence in
44 We reviewed records for admissions that occurred within 30 days of the last beneficiary discharge. Therefore, the 30-day window for reviewing readmissions did not span a fixed timeframe but began on the unique final discharge date for each beneficiary with the last possible admission occurring on November 30, 2008 (30 days following the final possible October 31, 2008, discharge).
45 Based on OIG interviews with IHI staff, IHI defines a cascade event as one in which an initial event causes a series of related events for the same patient and advocates collapsing these into a single event.

the medical records, including the actions of hospital and medical staff and the patient’s condition. Assessing an event as clearly preventable or clearly not preventable required a greater degree of certainty on the part of the reviewer. For detailed information about the methodology for identifying events and determining preventability, see Appendix E.
Data Analysis
We performed analysis and generated estimates about adverse events for three categories: incidence of events, preventability of events, and Medicare cost associated with events. We also calculated separate estimates regarding these categories for temporary harm events. For estimates and corresponding 95-percent confidence intervals for all statistical analyses, see Appendix F.
Adverse event incidence analysis. We calculated the estimated national adverse event incidence rate as the percentage of Medicare beneficiaries with at least one adverse event. We defined adverse events as events that met at least one of the following criteria:
1. the event was on the NQF list of Serious Reportable Events, as the Act mandates;
2. the event was on Medicare’s list of HACs for which it denies higher payment; or
3. the event resulted in one of the four most serious categories on the NCC MERP index (classified on the index as F-I): – prolonged hospital stay, – permanent harm, – life-sustaining intervention, or – death.
We also calculated individual rates for adverse events on the NQF list, the Medicare HAC list, and events classified as F-I on the NCC MERP index. The overall adverse event incidence rate does not include events that physician reviewers identified as temporary harm events, defined as events that required intervention but did not cause lasting harm (classified as E level harm on the NCC MERP index). We excluded these temporary harm events from our overall rate because we determined, in consultation with physician reviewers, that the effect of these events was not comparable to the more serious events meeting the three criteria. We calculated a separate incidence rate for beneficiaries who experienced only temporary harm events. We projected incidence rates to the population of Medicare beneficiaries discharged from inpatient acute care hospital stays during October 2008.

As
an additional measure of adverse event rates, we calculated 2 ratios of adverse event incidence density: events per 1,000 patient days and events per 100 hospital admissions. These measures are commonly used by hospitals and medical researchers.46 For the resulting metrics and an explanation of the calculation method, see Appendix G.
P
reventability analysis. The findings related to preventability are based on determinations made by the physician reviewers for each adverse event and temporary harm event. We calculated percentages for each preventability classification and for different types of events, the results of which are projectable to the population. We also conducted statistical tests to identify differences in preventability rates between adverse events and temporary harm events and across various categories of adverse events, such as medication-related and infection-related events.
M
edicare cost analysis. We estimated the cost to Medicare resulting from care associated with adverse events and temporary harm events. This analysis included only Medicare claims that were paid under the IPPS and were subject to the Medicare HAC policy (84 percent of sample beneficiaries). Certified medical coders reviewed the medical records, the medical review protocols, and the associated Medicare claims to identify diagnosis and procedure codes that would not have been included in the claims if the events had not occurred. We then used CMS’s MS-DRG Grouper and Medicare Code Editor Version 27 (Grouper) to determine the DRG for the claims and used the FY 2009 IPPS personal computer Pricer (Pricer) to determine the resulting Medicare reimbursement amounts. For each claim, we calculated the DRG and reimbursement amount, including information from the 4748

47 The cost analysis does not include claims for beneficiaries whose Medicare coverage is not paid under the IPPS. This includes Medicare managed care organizations and care provided at hospitals excluded from the Medicare IPPS system, including hospitals in the State of Maryland and some specialty hospitals nationwide, such as cancer treatment centers and critical access hospitals. CMS, HAC Fact Sheet. Accessed at http://www.cms.gov/HospitalAcqCond/Downloads/HACFactsheet.pdf on September 29, 2010.
48 The Grouper software classifies hospital claims into MS-DRG categories expected to have similar hospital resource requirements. MS-DRGs are based on the nine diagnoses associated with HACs and corresponding POA indicators, six procedure codes, and demographic data contained in the NCHs. MS-DRGs typically split into two or three individual classes based on the presence of a complication or comorbidity. This software was developed by CMS and 3M and is sold by the National Technical Information Service. Accessed at http://www.ntis.gov on September 29, 2010.

hospital Medicare claim. We then calculated the reimbursement amount excluding diagnosis and procedure codes that coders determined were the direct result of any adverse event or temporary harm event experienced by the beneficiary. We projected the difference between the two hospital reimbursement amounts to estimate the additional cost to Medicare for care associated with events. When an entire hospital stay was the result of an adverse event, we included the total reimbursement amounts indicated by the Pricer as the cost of the adverse event.
Limitations
Beyond the challenges associated with identifying adverse events and assessing preventability, the methodology presents two specific limitations. First, it is unlikely that the study identified all adverse and temporary harm events within the sample. To the extent that the study did not identify an event, it was likely because the three screening methods failed to flag the case for physician review or because documentation in the medical records was incomplete. Second, cost estimates did not include all costs of care associated with events, excluding stays not covered under the Medicare IPPS, additional hospital stays caused by sample events but occurring after October 2008, additional care outside the hospital (such as followup physician office visits or rehabilitation services), and changes in Medicare outlier payments.49
Standards
This study was conducted in accordance with the Quality Standards for Inspections approved by the Council of the Inspectors General on Integrity and Efficiency.
49 Medicare outlier payments are supplemental payments to hospitals for patients who incur extraordinarily high costs. Outlier payments are based on the degree to which costs on a claim exceed specific hospital and MS-DRG fixed-loss thresholds and fluctuate depending on the MS-DRG to which the claim is grouped. The Pricer analysis involved a revision of the MS-DRG. This revision resulted in new outlier payments for three sample cases and increased outlier payments for two sample cases. The revised outlier payments decreased the cost attributed to adverse events in our estimate.

Of the nearly 1 million Medicare beneficiaries discharged from hospitals in October 2008, about 1 in 7 experienced an adverse event (13.5 percent), defined as an event that met at least 1 of the following 3 criteria: the event was on the NQF list of Serious Reportable Events; the event was on Medicare’s list of HACs; or the event resulted in 1 of the 4 most serious categories on the NCC MERP index (prolonged hospital stay, permanent harm, life-sustaining intervention, or death). This incidence rate projects to approximately 134,000 Medicare beneficiaries experiencing at least 1 adverse event in hospitals during the study period. Table 2 lists the incidence rate for each of the three criteria.

unrelated events in the same hospitalization. For example, an elderly heart patient with a history of mental illness experienced three adverse events of different types, including two events that prolonged hospitalization and a third that required life-sustaining intervention. (This beneficiary also experienced three temporary harm events associated with patient care.)
Less than 1 percent of Medicare beneficiaries experienced an event on the NQF list of Serious Reportable Events
An estimated 0.6 percent of Medicare beneficiaries experienced an event on the NQF list, which projects to approximately 6,400 beneficiaries nationally for the study period. The low number of NQF events in the sample is notable because of the prominence of the list as a measure of patient harm and its use by a number of State adverse event reporting systems and other entities. We identified a total of five NQF events in the sample: two medication-related deaths and three Stage III pressure ulcers.50 One of the medication-related deaths illustrates the nature of the NQF list as a measure of the most egregious preventable outcomes. In this case, a disabled Medicare beneficiary with muscular dystrophy affecting the respiratory system entered the hospital for signs of respiratory failure. Medical staff at the hospital gave the beneficiary a medication known to further suppress respiration, resulting in progressive respiratory distress and subsequent death. Physician reviewers concluded that medical staff administered the wrong medication because they lacked clinical understanding of the patient’s unique condition.
Many serious events that we identified were not on the NQF list of Serious Reportable Events, including some events that resulted in patient deaths and serious disability. The NQF list focuses largely on serious disability or death, but is restricted to a specific set of events. Of the 18 adverse events that physician reviewers found to result in serious disability or patient death, only 2 were on the NQF list (i.e., the medication errors resulting in death). The three Stage III pressure ulcers identified in the sample were sufficiently treated prior to
50 Pressure ulcers are classified into four stages by the National Pressure Ulcer Advisory Panel (NPUAP): Stage I is intact skin with nonblanchable redness; Stage II is a shallow ulcer or blister indicating damage to the epidermis; Stage III is damage extending through all the layers of the skin; and Stage IV is damage through all the layers of the skin and underlying muscle, tendons, or bone.

discharge from the hospital and determined by physicians to have caused only temporary harm.
Medicare HACs rarely occurred, affecting just 1 percent of beneficiaries
An estimated 1 percent of hospitalized Medicare beneficiaries experienced Medicare HACs, which projects to approximately 10,000 beneficiaries nationally. We identified a total of nine Medicare HACs experienced by beneficiaries in the sample: five catheter-associated urinary tract infections, two vascular catheter-associated infections of the central line, one patient fall resulting in injury (a compression fracture), and one Stage III pressure ulcer. One beneficiary experienced two of these events, resulting in a total of eight sample beneficiaries with Medicare HACs. Two catheter-associated urinary tract infections caused more substantial harm than is typically associated with this condition: one resulted in a prolonged hospital stay and the other in permanent harm. The two vascular catheter-associated infections of a central line resulted in prolonged hospital stays. None of the nine Medicare HACs identified by physicians on the medical records were included in the associated Medicare claims. In four of the nine cases (all catheter-associated urinary tract infections), diagnosis codes on the claims identified the infections, but they were not the precise codes that CMS uses to identify these HACs. The other five claims had no diagnosis codes related to the HACs. Therefore, the HACs were not identifiable through the claims data that CMS uses to implement the HAC policy.
Thirteen percent of Medicare beneficiaries experienced adverse events classified in the most serious categories on the NCC MERP harm index
Based on our physician medical review, 13.1 percent of Medicare beneficiaries experienced adverse events classified in the four most serious harm categories on the NCC MERP harm index: events resulting in prolonged hospital stay, events resulting in permanent harm, events requiring life-sustaining intervention, and events contributing to death. This rate projects nationally to approximately 130,000 beneficiaries experiencing such adverse events during the study period. Often, adverse events within the same clinical category, such as infection, resulted in a different level of harm depending on the intervention required and the condition of the patient. Table 4 lists the percentage of adverse events in the sample that were classified in the four most serious harm categories and the projected national numbers of events by level of patient harm.

An estimated 1.5 percent of hospitalized Medicare beneficiaries experienced events that contributed to their deaths Among the 128 adverse events that we identified in the sample, 12 events (9 percent of 128 events) contributed to the deaths of beneficiaries. This projects to an estimated 1.5 percent of hospitalized Medicare beneficiaries experiencing events that contributed to death or approximately 15,000 beneficiaries during the study period. Seven of the twelve deaths were related to medication, either the result of improper administration of medication (wrong drug or wrong dosage) or inadequate treatment of known side effects. The most common type of medication-related death (five deaths) involved excessive bleeding from blood-thinning medication. The two other medication-related deaths involved inadequate insulin management resulting in hypoglycemic coma and respiratory failure resulting from oversedation. Of the five non-medication-related deaths, two were from bloodstream infections; two involved aspiration (which led to pneumonia and cardiac arrest, respectively); and the other involved a ventilator-associated pneumonia. As stated previously, only 2 of the 12 adverse events that contributed to death were on the NQF list and none were Medicare HACs.
Twenty-seven percent of beneficiaries who experienced adverse events had at least one “cascade” event, wherein multiple, related events occurred in succession
The sample included a total of 28 cascade events, defined as adverse events that included a series of multiple, related events. We counted these as single events. These cascade events were some of the most serious adverse events identified in the sample, with nine cases requiring life-sustaining intervention and six cases contributing to death. The most common type of cascade events were events related to

surgery and other procedures (nine events). Two of these events began with excessive bleeding following surgery or a procedure. For example, one beneficiary had excessive bleeding after his kidney dialysis needle was inadvertently removed, which resulted in circulatory shock, a transfer to the intensive care unit, and emergency insertion of a tube into the trachea (windpipe) to ease breathing. When the tube was removed the following day, the patient aspirated (inhaled foreign material into his lungs), which required a life-sustaining intervention.
An additional 13.5 percent of Medicare beneficiaries experienced events during their hospital stays that resulted in temporary harm
An additional 13.5 percent of Medicare beneficiaries experienced events during the study period classified as E level harm on the NCC MERP index, defined as events that required medical intervention but did not cause lasting harm. This rate projects to approximately 134,000 Medicare beneficiaries experiencing temporary harm events during the study period. Of these beneficiaries, 22 percent had more than one unrelated event (the highest occurrence was five unrelated events in a single hospital stay). Additionally, 28 percent of beneficiaries who experienced adverse events (and are included in our primary rate) also had temporary harm events during the same stay.
Events classified as temporary harm represented a wide array of conditions, such as prolonged vomiting and hypoglycemia (see Table 5). The most common events related to medication (42 percent). Although many cases of temporary harm represented fairly minor occurrences, we classified others as temporary because the patients were in the hospital for a lengthy period because of other, more serious, diagnoses, allowing the hospital enough time to address the harm prior to discharge. Physician reviewers indicated that many temporary harm events could have developed into more serious adverse events, but hospitals provided timely intervention. For example, Stage I or Stage II pressure ulcers can escalate quickly to Stage III or Stage IV without proper care51 and episodes of hypoglycemia can lead to stroke and even death.52

Physician reviewers determined that 44 percent of adverse events and temporary harm events were clearly or likely preventable
Physician reviewers assessed the extent to which events were preventable based on information in the medical records, their clinical experience with similar circumstances, research literature about the preventability of specific events, and group discussion to reach consensus. Combining adverse events and temporary harm events, physicians determined that 44 percent were preventable and 51 percent were not preventable.53 (There was no statistically significant difference between the preventability rates of adverse events and temporary harm events.)54 For the remaining 5 percent of events, physicians were unable to make determinations because of incomplete documentation in the medical records or extreme complexities in the patients’ conditions or in the hospital care provided. Table 6 provides the percentage of events by the physician preventability assessment.

Physician reviewers assessed the preventability of events similarly for three of the four clinical categories (medication, patient care, and infections). However, events related to surgery and other procedures were significantly less likely to be determined preventable than events in the other three clinical categories; only 17 percent of surgical events were

preventable in contrast to 50 percent or more in each of the other three groups.55 Physician reviewers indicated that the reasons surgical events were more likely to be assessed as not preventable were the high level of complexity in both the care involved and the patients’ conditions.

Within the clinical categories, physician reviewers sometimes gave the same preventability assessment for events with similar characteristics. For example, they assessed 10 of 12 events related to allergic reactions as not preventable. But for other types of events, preventability determinations for similar events differed based on the patients’ conditions and risk factors. For example, in two cases of excessive stomach bleeding caused by blood thinners, physicians assessed one event affecting a relatively healthy patient as preventable and the other event affecting a patient with stomach ulcers as not preventable because of the patient’s susceptibility. In another case, physician reviewers determined that some pressure ulcers were not preventable because of the poor conditions of the patients and because documentation in the medical records showed that the hospital staff employed appropriate preventive care. However, physicians assessed another pressure ulcer case as preventable because the medical staff declined to order a specialty mattress for an at-risk bedridden patient until after the pressure ulcer had developed, even though the medical record indicated that the specialty bed was available.
55 The Cochran-Mantel-Haenszel chi square test was significant at the 95-percent confidence level for the overall relationship between preventability and clinical category (p<0.0001) as well as for each set of pair-wise comparisons between the surgical category and each of the other three clinical categories (p<0.01 for each pair). Preventability rates were 62 percent for infections, 50 percent for medication, and 50 percent for patient care.

Counting only preventable events, the estimated national incidence rate of adverse events among Medicare beneficiaries would be 7.4 percent
The estimated adverse event incidence rate of 13.5 percent is based on all adverse events’ meeting one of the three criteria, regardless of whether the events were preventable. Including only the adverse events determined by physician reviewers to be clearly or likely preventable, the estimated incidence rate of adverse events among Medicare beneficiaries would be 7.4 percent. The 13.5 percent rate of additional beneficiaries experiencing temporary harm events would be 6.3 percent if only preventable events were included.
Eleven of the thirteen NQF Serious Reportable Events and Medicare HACs in the sample were preventable, a key criterion of both lists
Although we found few in the sample, all but two adverse events on the NQF and HAC lists were assessed as clearly or likely preventable.56 After the adverse events on each list were separated, four of the five events on the NQF list were preventable and eight of the nine Medicare HACs were preventable (one event was on both lists). A key criterion of both lists is that the events be largely preventable. The two events on the lists that physicians assessed as not preventable were (1) an NQF event consisting of a pressure ulcer that progressed from Stage I to Stage III in a chronically ill patient with multiple complications and susceptibility to skin breakdown and (2) a Medicare HAC consisting of a compression fracture incurred during a fall by a morbidly obese patient.
Preventable events were most commonly linked to medical errors, substandard treatment, and inadequate patient monitoring or assessment Physician reviewers selected one or more rationales to support each preventability determination from a list developed by the physician panel. To develop these rationales, physicians gleaned information from medical records, such as clinical staff actions, hospital environmental factors, and patient condition unrelated to the event. Among events assessed as preventable, 58 percent were linked to errors by clinical staff in medical judgment, skill, or patient management. Such errors often involved prescribing or administering the wrong medication. Nearly half of preventable events (46 percent) involved care provided in a substandard way, most frequently because of delay in diagnosis or
56 The number of NQF and HAC events was too small to test the preventability measure for statistical significance with an acceptable degree of precision or to project the measure to the national sampling frame.

Other common factors associated with preventable events were inadequate monitoring of patients (38 percent) and inadequate assessment of patients (23 percent). These factors often led to delays in treatment and worsening of patient conditions. In several of these cases, patients displayed symptoms of infection but were not given antibiotics until they reached the point of sepsis. In one case, the patient exhibited signs of shock upon arrival at the hospital, but clinical staff did not monitor the patient’s blood pressure for the first 8 hours and did not provide related treatment for another 16 hours. This delay caused the patient to experience severe hypotension, requiring life-sustaining intervention.

Physician reviewers assessed events as clearly or likely not preventable when the events occurred despite proper procedures or when the patients were highly susceptible to the events For 62 percent of the nonpreventable events in our sample, physician reviewers found that care was rendered according to accepted standards of practice. In these cases, physicians determined that the care provided was sufficient and appropriate and that there was no evidence of errors or other problems. This rationale was often given in combination with the second most common factor—that the patients’ other conditions made them highly susceptible to the event (50 percent of nonpreventable events). For example, one beneficiary, admitted to the hospital with a bowel obstruction, experienced a surgical cut of the intestine that would have been difficult to avoid because of significant damage to the bowel from prior surgery.
Other common rationales for assessing events as not preventable also focused on the difficulty of providing care. For 35 percent of nonpreventable events, physicians determined that the medical and hospital staff could not have anticipated the events given information available about the patients at the time of care delivery. For 29 percent of nonpreventable events, physicians determined that the patients’ diagnoses were unusual or complex, making care particularly difficult. Finally, in 14 percent of nonpreventable cases, the adverse events were anticipated by caregivers, but the harm associated with the adverse events was considered less harmful than not providing care. For example, in four sample cases, patients experienced harm as a result of an overload of intravenous fluid, yet the medical review found that the patients were in such dire need of fluids (e.g., at risk for hypoglycemic shock) that caregivers had little choice but to execute vigorous intravenous fluid replacement despite the risk of overload.

Hospital care associated with adverse events and temporary harm events cost Medicare an estimated $324 million in October 2008
Sixteen percent of sample beneficiaries under the Medicare IPPS who experienced events incurred additional Medicare hospital costs as a result. Most of the additional costs (87 percent) resulted from care associated with adverse events, with temporary harm events generating the remaining costs.57 These additional costs project to an estimated $324 million, which equates to 3.5 percent of the $9.2 billion that Medicare spent for inpatient care during October 2008.58 To give these figures an annual context, 3.5 percent of the $137 billion Medicare inpatient expenditure in FY 2009 equates to $4.4 billion spent on care associated with adverse events.59
Costs associated with preventable events accounted for an estimated $119 million of the $324 million additional cost, equating to 1.3 percent of the $9.2 billion Medicare inpatient expenditures for the month or about $1.8 billion annually.
Despite this outlay, most events did not affect Medicare costs; none of the Medicare HACs resulted in a higher reimbursement
Of beneficiaries who experienced adverse events or temporary harm events in hospitals covered under the Medicare IPPS, 84 percent did not incur additional costs for care associated with the events. This occurred primarily because many Medicare claims for beneficiaries who experienced events did not include diagnosis or procedure codes relating to the events. When Medicare claims included codes associated with the events, the codes often had no effect on costs because the claims included other costly diagnoses or procedure codes that elevated the reimbursement to equivalent or higher amounts.
57 One Medicare claim included codes for two events—one adverse event and one temporary harm event—and incurred an identical payment impact. This claim overlaps both groups and consequently the percentages do not total 100 percent: 87 percent of costs resulted from care associated with adverse events and 15 percent of costs resulted from care associated with temporary harm events.
58 These cost estimates include only claims under the IPPS, representing 708 sample Medicare claims (85 percent), but do not include costs for the remaining 130 sample beneficiaries (15 percent) who had sample admissions not covered under IPPS.
59 The annual cost estimate of $4.4 billion is 3.5 percent of the $137 billion Medicare inpatient costs for FY 2009, which assumes the same proportion of costs for adverse events for the other 11 months that we found in October 2008. Annual Medicare inpatient cost figures are from CMS, 2009 CMS Statistics Book, Table III.6, Office of Research, Development, and Information, CMS Pub. No. 03497, December 2009, p. 30.

None of the nine Medicare HACs identified in the sample resulted in a higher level of Medicare reimbursement. Although the Medicare HAC policy is intended to limit costs associated with the specified events, our review showed that none of the HACs in the sample would have invoked a higher Medicare reimbursement. None of the associated Medicare claims included the specific diagnosis codes that CMS uses to identify HACs. However, even if the codes had been included on the claims, the HAC policy would still not have resulted in payment reductions for these cases because other diagnosis or procedure codes would have elevated the reimbursement to a higher amount.
Two-thirds of Medicare costs associated with events were the result of additional hospital stays necessitated by harm from events
Sixty-five percent of the additional costs to Medicare ($210 million of the $324 million) were the result of entire, additional hospital stays required to treat the harm resulting from the adverse events. In some of these cases, the events occurred during outpatient services at the hospital (such as an emergency room visit or an outpatient surgery) and necessitated unplanned admissions to the inpatient facilities. In other cases, the events occurred during inpatient care and the beneficiaries were released from the hospital, but the aftereffects of the events necessitated subsequent hospital stays within the study period. The average Medicare cost of these additional hospital stays for sample beneficiaries was $13,745, compared with an average additional cost of $5,601 for event-related care that hospitals provided during the initial hospital stay in situations that did not necessitate additional stays.60, 61
Medicare cost estimates do not include additional costs required for followup care after the sample hospitalization
Because our cost analysis included only hospital stays that ended during October 2008, Medicare costs associated with care resulting from adverse events and temporary harm events are greater than our estimate. Beneficiaries may have had additional event-related hospital stays beyond our study period and may have incurred expenses to Medicare or personal expenses for followup care not reflected in inpatient claims, such as physician office visits, medication, and rehabilitation services during and after our study period.
60 Averages reflect only costs greater than zero.

As an example of an event resulting in subsequent Medicare costs not captured by our cost analysis, one sample beneficiary was initially admitted to the hospital in mid-October 2008 for a stroke. During this hospital stay, he experienced an allergic reaction to medication and was discharged with no additional cost associated with the event. However, following discharge, the allergic reaction progressed to a life-threatening condition known as Stevens-Johnson Syndrome.62 The beneficiary returned to the hospital during October for treatment, incurring the cost of an entire hospital stay as a result of the event, but was misdiagnosed and again discharged. The patient then incurred two additional hospital stays within the next 30 days to correctly diagnose and treat the condition. The total estimated inpatient cost to Medicare for the latter three hospital stays was $43,050, all necessitated by the event. Only $10,982 of this amount was incurred during the study period and included in our cost estimate. Physician reviewers determined that the medication-related event was preventable because the medication was known to be highly reactive and the condition was not diagnosed correctly, delaying treatment.
62 This condition typically begins with a skin rash and fever and, if untreated, progresses to an array of conditions constituting serious harm, such as lung damage and renal failure.

RECOMMENDATIONS
In the decade since the IOM report, the need to improve patient safety has received much attention from Federal and State governments, advocacy groups, and the health care industry. Despite this attention, we found that 13.5 percent of Medicare beneficiaries experienced adverse events during their hospital stays in October 2008, most of which resulted in prolonged hospital stays, permanent harm, life-sustaining interventions, or death. An additional 13.5 percent of beneficiaries experienced temporary harm as the result of events. Physician reviewers determined that 44 percent of events were preventable and that preventable events often involved medical errors, substandard care, and inadequate monitoring or assessment of patients. We found that in addition to causing the harm to patients, adverse events and temporary harm events increased costs to Medicare by an estimated $324 million in a single month, or 3.5 percent of Medicare inpatient expenditures, suggesting potential savings from reducing the incidence of events.
As the Federal Government’s principal agency for protecting the health of Americans,63 HHS is uniquely positioned to lead national efforts to reduce adverse events in hospitals. As part of the national strategy to improve health care quality mandated by the ACA, HHS is to “identify areas in the delivery of health care services that have the potential for rapid improvement in the quality and efficiency of patient care.”64
Because many adverse events that we identified were preventable, our study confirms the need and opportunity for hospitals to significantly reduce the incidence of events. A number of agencies within HHS share responsibility for addressing this issue, most prominently AHRQ as a coordinating body for efforts to improve health care quality and CMS as the Nation’s largest health care payer and an oversight entity.
Therefore, we recommend the following:
AHRQ and CMS should broaden patient safety efforts to include all types of adverse events Efforts to improve patient safety often focus on a small subset of events that harm hospital patients. For example, NQF Serious Reportable Events or Medicare HACs represented only a fraction of

R E C O M M E N D A T I O N S
the adverse events we identified in this report. Additionally, patient safety provisions in the ACA often refer specifically to reducing medical errors, rather than to the broader range of adverse events. AHRQ and CMS should avoid focusing patient safety efforts too narrowly on a small list of specific events, possibly failing to address the wider array of events that lead to most instances of patient harm. Rather, AHRQ and CMS should promote a definition of adverse events that more fully encompasses harm resulting from medical care. This broader definition would apply to a number of patient safety activities, including setting priorities for research, establishing guidelines for hospital reporting of events, developing prevention strategies, measuring health care quality, and determining payment policies.
AHRQ and CMS should enhance efforts to identify adverse events Identifying adverse events assists policymakers and clinical researchers in directing prevention resources to the areas of greatest need, setting clear goals for improvement, assessing the effectiveness of specific strategies, holding hospitals accountable, and gauging progress in reducing incidence.
AHRQ should sponsor periodic, ongoing measurement of the incidence of adverse events. To facilitate measurement, AHRQ should establish a standard protocol for identifying events and analyzing information about incidence and causes. AHRQ should also consider providing hospitals with methods for measuring their incidence of events, goals for incidence reduction, and benchmarks or other means for comparing rates among providers.
AHRQ should continue to encourage hospitals to report to PSOs. Hospital reporting of adverse event information to PSOs can provide AHRQ with aggregated data about the nature and causes of events. To maximize the usefulness of PSO-reported data for national measurement and analysis, AHRQ should continue working toward establishing standard adverse event definitions and reporting formats and encouraging hospital reporting.
CMS should use POA indicators in hospital billing data to calculate the frequency of adverse events occurring within hospitals. These POA indicator data represent a rich source of information for identifying certain adverse events in claims data. CMS should establish routine methods for using POA indicators to guide patient safety improvement efforts. For example, CMS could direct that
OEI – 0 6 – 0 9 – 0 0090 ADVERSE E VENT S I N HOS P I TAL S: NAT ION AL I N C IDEN C E AMONG MEDI C A R E BENEFI C I A R I ES 31
R E C O M M E N D A T I O N S
QIOs use POA indicators to monitor hospital rates of specific conditions.
CMS should provide further incentives for hospitals to reduce the incidence of adverse events through its payment and oversight functions CMS, as both a payer and an oversight entity, is positioned to influence hospitals to provide high-quality care. CMS should explore avenues to reduce the incidence of adverse events through both program participation and payment policy.
CMS should strengthen the Medicare HAC policy. We found that HACs represent a small proportion of preventable events and that they are not always coded as such in Medicare claims. The ACA makes several changes to the HAC policy, including allowing the Secretary to expand the list of HACs. The law also gives the HAC policy greater significance by using the list of HACs to implement Medicare payment penalties, create performance measures, and prohibit Medicaid payments for associated care. Given their low incidence, continued use of the 10 HACs already established by CMS may limit the intended effect of the statute. To strengthen the policy, CMS should consider expanding the list of Medicare HACs to include more conditions that may result in harm to beneficiaries. CMS should also take additional steps to ensure that hospitals accurately code Medicare claims to show when HACs occur, as recommended in our prior report.65
CMS should look for opportunities to hold hospitals accountable for adoption of evidence-based practice guidelines. The conditions of participation for Medicare and Medicaid require that hospitals have programs to demonstrate quality improvement where evidence shows practices can improve outcomes. CMS should further influence hospitals to reduce adverse events through enforcement of the conditions of participation. This could include more closely examining patient safety issues through the survey and certification process, as recommended in our prior report.66 This could also include encouraging hospitals to adopt evidence-based practices shown to prevent adverse events.

GENCY COMMENTS
We received comments on the draft report from AHRQ and CMS.
AHRQ. AHRQ concurred with our recommendations, stating that adverse events affect hospital patients at an “alarming rate” and that it must continue working to improve patient safety.
I
n response to our recommendation to broaden patient safety efforts to include all types of adverse events, AHRQ noted that the types of events vary widely and that efforts should be broadened beyond prescribed lists of adverse events. AHRQ stated that it has sponsored efforts to address specific types of adverse events and to address causes that contribute to a wide variety of adverse events. AHRQ also cited the recent development of its Common Formats, a set of event definitions and reporting forms not limited to a specific list of events designed for hospitals to use to report events to PSOs.
In response to our recommendation to enhance efforts to identify adverse events, AHRQ stated that it intends to foster continued improvement in both identifying and reducing adverse events through operational programs, research efforts, and further collaboration with other agencies. Specifically, AHRQ noted that the Common Formats facilitate identification of events for both internal hospital purposes and reporting to PSOs. AHRQ also cited a continued commitment to its Patient Safety Indicators methodology as a way to identify events in administrative data and a planned expansion of the MPSMS program, which identifies adverse events in medical records acquired through CMS. AHRQ plans to expand the MPSMS by broadening the areas of clinical investigation, seeking to address all patient populations rather than only Medicare beneficiaries, and working toward sharing the MPSMS methodology with other organizations.
CMS. CMS concurred with our recommendations and stated that it is committed to the reduction of adverse events in hospitals and other health care settings. CMS provided details about current activities and future plans to reduce adverse events, concluding that although it has taken significant steps to address these issues, more work needs to be done.
In response to our recommendation to broaden patient safety efforts to include all types of adverse events, CMS stated that it will “aggressively pursue” broadening the scope and definition of patient safety efforts to be more inclusive of various types of adverse events. As an example,

R E C O M M E N D A T I O N S
CMS noted that it is expanding hospital reporting of quality data to include more measures of adverse events.
In response to our recommendation to enhance efforts to identify adverse events, CMS stated that it will continue to use POA indicators in implementing its Medicare HAC policy. CMS also referenced the use of POA indicators by QIOs to assist hospitals in reducing high-risk pressure ulcers and indicated that it is assessing the broader use of POA indicators by QIOs to assess the incidence of adverse events and assist hospitals in developing quality improvement plans.
In response to our recommendation to provide further incentives for hospitals to reduce the incidence of adverse events through payment and oversight, CMS stated its commitment to more closely monitor and address hospital quality of care. Specifically, CMS plans to strengthen the Medicare HAC policy by considering the appropriateness of expanding the conditions included, applying the policy to more health care settings, and working to improve the coding and reporting of POA indicators. CMS also stated that it is working toward improving evaluation of the hospital conditions of participation related to patient safety, developing interpretive guidelines and training for surveyors, and tasking QIOs with greater responsibility to address adverse events in hospitals. Further, CMS points to opportunities presented by the ACA, including implementation of the Hospital Value-Based Purchasing Program, which will use hospital performance as a basis for incentive payments; and creation of the Center for Medicare & Medicaid Innovation, which will address improvement in patient safety and reduction of adverse events.

Acute renal insufficiency—Sudden loss of the kidneys’ ability to remove waste, also referred to as acute kidney failure.
Adverse event—Harm to a patient as a result of medical care. For purposes of this study, we defined adverse events as events that met at least one of the following criteria: an event on the National Quality Forum list of Serious Reportable Events; an event on Medicare’s list of hospital-acquired conditions (HAC) for which it denies higher payment; or an event resulting in one of the four most serious categories on a patient harm index (classified on the index as F-I): prolonged hospital stay, permanent harm, life-sustaining intervention, or death.
Anticoagulant—Medication that hinders blood coagulation, typically used to avoid blood clots and referred to as blood-thinning medication.
Aspiration—Accidental inhalation of foreign material into the lungs.
Congestive heart failure—Condition in which the heart is unable to maintain adequate circulation of blood in the tissues of the body.
Deep vein thrombosis (DVT)—Formation of a thrombus (blood clot) within a deep vein (as of the leg or pelvis) that is life threatening if dislodgment results in blockage to the pulmonary (lung) artery.
Delirium—Mental disturbance characterized by confusion, disordered speech, and hallucinations.

Methodology for Identifying Events and Determining Preventability
Screening for Potential Adverse Events
We conducted a two-stage review to identify adverse events. The first stage included three screening methods designed to identify beneficiaries who appeared likely to have experienced adverse events. A beneficiary was considered likely to have experienced an adverse event if any screening method found at least one potential adverse event during any of the beneficiary’s hospital stays. The screening process enabled us to reduce the number of cases requiring second-level review of the full medical records by a physician. Additionally, physician reviewers indicated that the results of the screening methods helped them to more readily identify potential adverse events for consideration.
The screening methods included:
analysis by certified medical coders of Present on Admission (POA) Indicators included in Medicare claims data to identify any diagnoses that were acquired during the hospital stay;
screening of medical records by nurse reviewers using a modified version of the Institute for Healthcare Improvement’s Global Trigger Tool (IHI GTT) for triggers that could indicate an event, such as laboratory test results indicating an infection; and
identification of any beneficiaries who were readmitted to the hospital within 30 days after their October 2008 hospital discharges.
Analysis of POA Indicators. Using data from the National Claims History file, certified medical coders reviewed the POA indicator data included in hospital Medicare claims for each sample beneficiary. A recent addition required of Medicare Part A claims, the POA indicator codes require hospitals to make a clinical distinction about whether diagnoses are present at the time of admission. The coders first verified the accuracy of each POA indicator by reviewing the medical records and then flagged each diagnosis that had a POA indicator of “N” (not present on admission), “W” (clinical staff unable to determine), or “U” (documentation insufficient to determine). Analysis of POA indicators identified 297 beneficiaries for the second stage of the review.
Nurse reviews of medical records. Contracted registered nurses conducted a preliminary review of medical records for each sample beneficiary to identify potential adverse events. Reviewers used a

A P P E N D I X ~ E
modified version of the IHI GTT protocol, in which reviewers identified triggers in the medical records possibly indicative of adverse events and then explored the records further to determine whether events occurred and the resulting level of harm. Medical records screening identified 372 cases for inclusion in the second stage of review.
Readmissions. We identified 92 sample beneficiaries who were readmitted to the hospital within 30 days after their discharges in October 2008 and included these cases in the second stage of review. We reviewed records for admissions that occurred within 30 days of the beneficiaries’ last discharges; therefore, the 30-day window for reviewing readmissions did not span a fixed timeframe but began on the discharge date for each beneficiary.
Flagged hospital stays. We identified 420 beneficiaries for the second stage of review, a review of the hospital medical records by physicians. Of the 420 beneficiaries, we identified 391 with the 3 screening methods and 29 from additional analysis. In the 29 additional cases, the beneficiaries were not flagged on the 3 screening methods, but staff involved in the screening process (nurses, coders, or analysts) believed complexities in the cases warranted physician review.
Identifying Events Within Flagged Cases
Five contracted physicians conducted medical records review of the 420 cases identified by the screening methods. Physician reviewers represented a variety of specializations and experience: an infectious disease specialist, a cardiologist, an orthopedic surgeon, an intensivist (intensive care specialist), and an internist. All five had many years of clinical experience, as well as prior experience in detecting adverse events in medical records. Three of the five served as physician reviewers for a 2008 Office of Inspector General (OIG) case study.69
Over 12 weeks, the physician reviewers examined hospital medical records for each of the 420 cases.70 Physician reviewers used a structured medical review protocol that required them to describe each adverse event; identify the medical record documentation that led to
69 OIG, Adverse Events in Hospitals: Case Study of Incidence Among Medicare Beneficiaries in Two Counties, OEI-06-08-00220, December 2008.
70 These included medical records for all hospital stays for sample beneficiaries ending with October 2008 discharges. Additionally, physicians reviewed records for any readmissions of sample beneficiaries that occurred within 30 days after their final October discharges to look for evidence of events that occurred during the October 2008-discharged stays.

their identification of the event; and specify the level of harm experienced by the patient, with harm categorized in accordance with the National Coordination Council for Medication Errors Reporting and Prevention Index of Categorizing Medication Errors.
Throughout our study preparation, medical records review, and analysis, we facilitated 22 weekly conference calls during which the physician reviewers discussed the review protocol and sample cases that either were complex or had possible implications for other cases. These calls assisted in making determinations for difficult cases and helped achieve consistency across reviewers. The physicians determined that the following types of cases would require group discussion: events assessed as clearly preventable; events contributing to death; and cases involving respiratory failure, hypoglycemia, hypotension, urinary tract infections, and complex and/or lengthy surgeries. Physicians also often brought cases to group discussion if they involved care specific to a specialization of another physician. We documented the discussions and conclusions made during these weekly calls, continually revising a written physician guidance document to further promote consistency. The physicians discussed 162 of the 302 events (54 percent) and other cases that the group ultimately determined did not include events.
Determining Preventability for Each Event
As part of the structured medical review protocol, reviewers also assessed the likelihood that the events were preventable. In collaboration with the physicians, we created an initial response scale:
Preventable—Patient harm could have been avoided through improved assessment or alternative actions.
Not preventable—Patient harm could not have been avoided given the complexity of the patient’s condition or the care required.
Unable to determine—Physicians were unable to determine preventability because of incomplete documentation or case complexity.
Through the pretest process, we expanded the scale to enable physicians to more precisely gauge the extent to which an event was preventable. The expanded scale divided the preventable and nonpreventable responses with the descriptors clearly and likely. Assessing an event as clearly preventable or clearly not preventable required a greater degree of certainty on the part of the reviewer. The expanded scale enabled OEI – 0 6 – 0 9 – 0 0090 ADVERSE E VENT S I N HOS P I TAL S: NAT ION AL I N C IDEN C E AMONG MEDI C A R E BENEFI C I A R I ES 43

physicians to make more precise determinations, while our primary statistics continued to collapse clearly and likely.
T
o make distinctions about the circumstances in each case, physicians used their clinical experience and judgment. They considered all evidence in the medical records, including staff actions and the patient’s condition. Physicians also used information about accepted standards of care, the frequency with which certain events occurred despite appropriate assessment and care, the physicians’ individual clinical experiences, guidance developed during the review process, and group discussion of cases. Using a list of contributing factors gleaned from prior research, physicians indicated the rationale for each determination and provided a narrative description for each case.
T
o improve consistency, physician reviewers used a uniform method for reviewing preventability. Reviewers developed a decision algorithm during practice reviews consisting of a series of questions that led the reviewers to a suggested response. Questions addressed issues such as whether there was a medical error, whether the event could have been anticipated, and how frequently the event occurred given proper care. Physicians did not automatically accept the suggested response, but assessed whether it was appropriate for each case. In completing the rationale section of the protocol, physicians assessed contributing factors. The list of contributing factors included broad concepts from the decision algorithm, such as errors, and more nuanced factors, such as whether the patient was monitored or was susceptible to the event. We required that physicians discuss all clearly preventable determinations during group meetings (as they required greater certainty), and encouraged them to bring other cases for discussion if they had difficulty or felt the cases would inform other determinations. Figure E-1 illustrates the preventability review process.
P
hysician Review of Findings
Following the medical records review, we analyzed the identified events, harm levels, and preventability determinations to identify any inconsistencies and discussed these with the full physician group. This process resulted in some changes to the initial determinations, such as collapsing a series of events into a single cascade event.71 44
71 Based on OIG interviews with IHI staff, IHI defines a cascade event as one in which an initial event causes a series of related events for the same patient and advocates collapsing these into a single event.

APPENDIX ~ G
Rates of Adverse Events and Temporary Harm Events by Patient Days and Hospital Admissions
Hospitals commonly measure adverse events by incidence density, which takes into account the period during which patients are observed. For example, incidence density is often used in measuring hospital-acquired infections because risk can increase with the length of exposure to the health care environment.72 The Institute for Healthcare Improvement (IHI), a nonprofit advisory group to hospitals, cites advantages to using incidence density metrics over standard incidence rates that measure the number of events per patient.73 IHI reports that measuring total events by patient days or hospital admissions enables hospitals to count multiple events experienced by the same beneficiary.
The sample of 780 Medicare beneficiaries discharged during October 2008 included 838 total hospital stays (admissions) and a total of 4,354 days in the hospital (patient days). We calculated patient days by subtracting the admission date for each hospital stay from its discharge date.74 Table G-1 provides ratios for adverse events and temporary harm events in the sample per 1,000 patient days and per 100 admissions.

74 In consultation with physician reviewers, we excluded the seven patients admitted and discharged on the same day (these patients did not experience temporary harm or adverse events). IHI recommends selecting patient records for only hospital stays of at least 24 hours.

Adverse Events and Temporary Harm Events
Tables H-1 and H-2 contain information about adverse events and temporary harm events identified in the sample, including National Quality Forum (NQF) Serious Reportable Events and Medicare hospital-acquired conditions (HAC). Table H-1 contains information about adverse events (128 adverse events).75 Table H-2 contains information about temporary harm events (174 events). The event descriptions vary somewhat depending upon the language the physician reviewers used to describe the event and the level of detail included in their notes.

SUBJECT: AHRQ Response to OIG draft report, Adverse Events in Hospitals: National Incidence Among Medicare Beneficiaries, OEI-06-09-00090.
Thank you for the opportunity to review your draft report, Adverse Events in Hospitals: National Incidence Among Medicare Beneficiaries, OEI-06-09-00090. The findings in the report are consistent with previous studies but are nonetheless disturbing. They confirm that adverse events continue to affect hospital inpatients at an alarming rate, and that the types of events that occur vary widely. The report reaffirms AHRQ's need to continue work on improving patient safety by broadening investigation to include areas that are not always seen on lists of adverse events that should never occur or should always be reported.
Responses are provided below to the report's two general recommendations that pertain to AHRQ and were provided in the July 20, 2010, draft version of the report that the Agency reviewed .
Recommendation: AHRQ and CMS should broaden patient safety efforts to include all types of adverse events.
AHRQ agrees that efforts to improve patient safety should be broad. While we have sponsored efforts to address specific types of adverse events, such as central-line-associated bloodstream infections and venous thromboembolisms, we have also supported efforts to address underlying causes that contribute to a wide variety of adverse events. For example, we have focused on improving the safety culture in healthcare by providing a widely-adopted patient safety culture survey that is used by hospitals and healthcare systems, and by providing team training to healthcare systems via the TeamSTEPPS program that we developed in concert with the Department of Defense. We have also provided broad in-person training on the topic of patient safety improvement to public sector and private sector representatives from every state via the Patient Safety Improvement Corps, which we implemented in concert with the Department of Veterans Affairs' National Center for Patient Safety. As we continue to lead and support Federal efforts in patient safety improvement, we intend to broaden efforts to improve patient safety overall (as with TeamSTEPPS), and to address specific problems, such as a targeted program to foster the widespread implementation of the CDC's guideline to prevent catheter-associated urinary tract infections.
Recommendation: AHRQ and CMS should enhance efforts to identify adverse events.
AHRQ has several efforts underway to improve identification of adverse event s. The Agency has developed Common Formats (current version 1.1) that provide standard definitions, data elements, and reporting formats for all adverse events that occur in the hospital setting. Because the Common Formats are designed to address all events, not just a targeted list, they are directly responsive to OIG's recommendation to "broaden patient safety efforts to include all types of patient safety events."

The Agency has developed Common Formats (current version 1.1) that provide standard definitions, data elements, and reporting formats for all adverse events that occur in the hospital setting. Because the Common Formats are designed to address all events, not just a targeted list, they are directly responsive to OIG's recommendation to "broaden patient safety efforts to include all types of patient safety events."

SUBJECT: AHRQ Response to OIG draft report, Adverse Events in Hospitals: National Incidence Among Medicare Beneficiaries, OEI-06-09-00090.
Thank you for the opportunity to review your draft report, Adverse Events in Hospitals: National Incidence Among Medicare Beneficiaries, OEI-06-09-00090. The findings in the report are consistent with previous studies but are nonetheless disturbing. They confirm that adverse events continue to affect hospital inpatients at an alarming rate, and that the types of events that occur vary widely. The report reaffirms AHRQ's need to continue work on improving patient safety by broadening investigation to include areas that are not always seen on lists of adverse events that should never occur or should always be reported.
Responses are provided below to the report's two general recommendations that pertain to AHRQ and were provided in the July 20, 2010, draft version of the report that the Agency reviewed .
Recommendation: AHRQ and CMS should broaden patient safety efforts to include all types of adverse events.
AHRQ agrees that efforts to improve patient safety should be broad. While we have sponsored efforts to address specific types of adverse events, such as central-line-associated bloodstream infections and venous thromboembolisms, we have also supported efforts to address underlying causes that contribute to a wide variety of adverse events. For example, we have focused on improving the safety culture in healthcare by providing a widely-adopted patient safety culture survey that is used by hospitals and healthcare systems, and by providing team training to healthcare systems via the TeamSTEPPS program that we developed in concert with the Department of Defense. We have also provided broad in-person training on the topic of patient safety improvement to public sector and private sector representatives from every state via the Patient Safety Improvement Corps, which we implemented in concert with the Department of Veterans Affairs' National Center for Patient Safety. As we continue to lead and support Federal efforts in patient safety improvement, we intend to broaden efforts to improve patient safety overall (as with TeamSTEPPS), and to address specific problems, such as a targeted program to foster the widespread implementation of the CDC's guideline to prevent catheter-associated urinary tract infections.
