Preventable medical errors kill and seriously injure hundreds of thousands of Americans every year. Any discussion of medical negligence that does not involve preventable medical errors ignores this fundamental problem. While some interested parties would prefer to focus on doctor’s insurance premiums, health care costs, or alternative compensation systems—anything other than the negligence itself—reducing medical errors is the best way to address all the related problems. Preventing medical errors will lower health care costs, reduce doctors’ insurance premiums, and protect the health and well-being of patients.


The Institute of Medicine’s (IOM) seminal study of preventable medical errors estimated as many as 98,000 people die every year at a cost of $29 billion. i If the Centers for Disease Control were to include preventable medical errors as a category, these conclusions would make it the sixth leading cause of death in America. ii

Further research has confirmed the extent of medical errors. The Institute for Healthcare Improvement estimates there are 15 million incidents of medical harm each year.iii HealthGrades, the nation’s leading healthcare rating organization, found that Medicare patients who experienced a patient-safety incident had a one-in-five chance of dying as a result.iv

Yet despite these numbers, the American public remains unaware of just how pervasive the problem is. Even though one in three Americans say that they or a family member has experienced a medical error, and one in five say that a medical error has caused either themselves or a family member serious health problems or death, surveys show that Americans vastly underestimate the extent of medical errors.v About half of respondents believe the annual death total from medical errors to be 5,000 or less—nearly 20 times lower than the IOM’s estimate.

People have been led to believe that there are hundreds of thousands of medical negligence lawsuits every year and only a handful of genuine medical errors. In reality, the reverse is true. There are very few medical negligence lawsuits, and hundreds of thousands dying from preventable medical errors. As University of Pennsylvania law professor Tom Baker puts it, “We have an epidemic of medical malpractice, not of malpractice lawsuits.”vi

Much of the discussion surrounding medical negligence revolves around costs, whether it be the cost of physicians’ insurance or the cost to health care. While these are the subject of much debate and acrimony, the potential savings from the elimination of medical errors are undeniable.

Dollars better spent on patient safety
The Center for Medicare & Medicaid Services (CMS) has, in recent years, recognized the potential for financial savings by reducing medical errors. CMS has stopped paying for hospital and practitioner errors, and thus created a financial incentive for hospitals to embrace patient safety. After evaluating a number of billable hospital-acquired conditions, CMS and the CDC decided on eight expensive but “reasonably preventable” secondary conditions that would not be reimbursed by Medicare, and could not be billed to patients.vii Previously, Medicare rewarded hospital errors with larger reimbursements, by paying them an extra amount to treat various preventable complications that developed as a result of hospital negligence.

The new rules, which went into effect in 2008, are expected to save taxpayers at least $21 million annually and will encourage hospitals to take steps to avoid “reasonably preventable” hospital acquired conditions. Private insurers like Blue Cross/Blue Shield Association and Aetna have also implemented similar policies not to reimburse medical providers for care related to problems or complications that should not occur in the normal course of hospitalization.ix
