Study Finds No Progress in Safety at Hospitals

The study, conducted from 2002 to 2007 in 10 North Carolina hospitals, found that harm to patients was common and that the number of incidents did not decrease over time. The most common problems were complications from procedures or drugs and hospital-acquired infections.

But instead of improvements, the researchers found a high rate of problems. About 18 percent of patients were harmed by medical care, some more than once, and 63.1 percent of the injuries were judged to be preventable. Most of the problems were temporary and treatable, but some were serious, and a few — 2.4 percent — caused or contributed to a patient’s death, the study found.
