U.S. hospitals are much safer now than 10 years ago, according to a study in the July 12 JAMA of adverse events in 3,156 randomly selected U.S. hospitals. Using data from the Medicare Patient Safety Monitoring System from 2010 to 2019, researchers examined adverse events affecting 244,542 patients in five diagnostic categories: myocardial infarction, heart failure, pneumonia, major surgical procedures, and all other conditions (such as pressure ulcers and falls). There were significant decreases in adverse drug, postprocedural, and general events and in hospital-acquired infections, with the greatest reduction in adverse drug events. The authors posit the decline may be related to major safety improvement efforts the hospitals had undertaken during that 10-year period as well as advancements in care.
