Connecticut hospitals reported record numbers of errors in 2013, with large increases in the numbers of falls, medication mistakes and perforations during surgical procedures, a new state report shows. The report, covering 2013, marks the first time that the number of so-called "adverse events" in hospitals and other health care facilities has topped 500 — double the number in 2012, when 244 such incidents were reported. Much of the increase was due to an expansion of reporting on pressure ulcers, which added a new category with 233 "unstageable" ulcers that were not counted before. Even without that category, however, reports of adverse events climbed 20 percent from 2012.
