Medical Malpractice Facts and Figures

In the United States, medical malpractice is estimated to result in 40,000 to 100,000 unnecessary deaths and 1,000,000 excess injuries each year. One older study suggests 180,000 people die each year partly as a result of medical error and negligence, the equivalent of three jumbo-jet crashes every two days. Some medical analysts estimate that as many as 102,000 people die in any given year from medical errors that occur in hospitals. That's more than the number who die from auto accidents, breast cancer, AIDS and workplace accidents -- four causes that receive far more public attention. Add to this, the financial cost to the human tragedy, and medical malpractice easily rises to the top ranks of public problems.

Medical malpractice claims can help identify areas where primary health care in the United States needs improvement, according to the American Academy of Family Physicians. The Academy refers to a study entitled "Learning from Malpractice Claims about Negligent, Adverse Events in are in the United States", in suggesting that the medical community can learn from tort claims. In that study, researchers looked at primary care malpractice claims settled between 1985 and 2000 in the United States. The study focused on a subset of 5,921 claims that were clear errors. The researchers found:

A recent study by Healthgrades found that an average of 195,000 hospital deaths in each of the years 2000, 2001 and 2002 in the U.S. were due to potentially preventable medical errors. Researchers examined 37 million patient records and applied the mortality and economic impact models developed by Dr. Chunliu Zhan and Dr. Marlene R. Miller in a study published in the Journal of the American Medical Association (JAMA) in October of 2003. The Zhan and Miller study supported the Institute of Medicine’s (IOM) 1999 report conclusion, which found that medical errors caused up to 98,000 deaths annually and should be considered a national epidemic.

Some researchers questioned the accuracy of the 1999 IOM study, reporting both significant subjectivity in determining which deaths were "avoidable" or due to medical error and an erroneous assumption that 100% of patients would have survived if optimal care had been provided. A 2001 study in JAMA estimated that only 1 in 10,000 patients admitted to the hospital would have lived for 3 months or more had "optimal" care been provided.

A 2006 follow-up to the 1999 Institute of Medicine of the National Academies study found that medication errors are among the most common medical mistakes, harming at least 1.5 million people every year. According to the study, 400,000 preventable drug-related injuries occur each year in hospitals, 800,000 in long-term care settings, and roughly 530,000 among Medicare recipients in outpatient clinics. The report stated that these are likely to be conservative estimates. In 2000 alone, the extra medical costs incurred by preventable drug related injuries approximated $887 million -- and the study looked only at injuries sustained by Medicare recipients, a subset of clinic visitors. None of these figures take into account lost wages and productivity or other costs.
