Patient Safety

The Opportunity

The Institute of Medicine (IOM) defined patient safety as “freedom from accidental injury due to medical care or medical errors.”1 Patient safety problems cause hundreds of thousands of preventable deaths each year—a recent analysis estimated that up to 440,000 Americans die annually from medical errors in U.S. hospitals.2 A 2010 study by the U.S. Department of Health and Human Services (HHS) Office of Inspector General (OIG) estimated that over a quarter of hospitalized Medicare beneficiaries experience an adverse event during their hospital stay; subsequent studies in other care settings estimated that the adverse event rates among Medicare patients in Skilled Nursing Facilities (SNFs) and rehabilitation hospitals are 33 percent and 29 percent, respectively. 3, 4, 5 Adverse events can take many forms, including healthcare-associated infections (HAIs), medication errors, falls, pressure ulcers, and other potentially avoidable occurrences. The costs of these events are high and are passed on in various ways—higher insurance premiums, taxes, lost work time and wages, and lower quality of life, to name a few. Proactively addressing patient safety will protect patients from harm and lead to more affordable, effective, and equitable care.
