You have a greater chance of dying of medical errors than of stroke, Alzheimer's, diabetes, the flu, pneumonia, or car crashes. That's according to a new analysis from researchers at the Johns Hopkins University School of Medicine in Baltimore.
They looked at research going back to 1999 and calculated that an estimated 251,454 Americans a year die from medical errors in hospitals—things such preventable infections, drug errors, mistaken diagnoses, and poor communication, especially upon discharge. In fact, medical errors account for more deaths than all other causes of death except for heart disease and cancer, according to this analysis.
And that likely underestimates the problem, say the study authors, Martin Makary, M.D., and Michael Daniel, M.D. "We believe this understates the true incidence of death due to medical error because the studies cited rely on errors extractable in documented health records and include only inpatient deaths," they wrote in their paper, which was published on May 3 by the BMJ.
In fact, previous research suggests that as many as 440,000 Americans a year die from medical errors in hospitals.
Part of the problem in establishing firm numbers, Makary and Daniel write, is that the Centers for Disease and Control and Prevention does not require that death certificates record medical errors. Currently, death certificates rely on assigning an International Classification of Disease (ICD) code to the cause of death—so deaths not associated with an ICD code, such as human and system errors, are not captured.
Makary and Daniel believe that preventing deadly errors in hospitals requires a multipronged approach, starting with greater accountability among hospitals to record and respond to medical errors. For example, they believe that hospitals should investigate all deaths to see if errors were a contributing factor.
Lisa McGiffert, the director of Consumer Report's Safe Patient Project, agrees that the CDC should require death certificates to include medical errors. "That would give us the data we need to really understand the scope of the problem, and also force hospitals to acknowledge how common and serious the situation is—and take steps to correct it, too."
