The overall number of “adverse events” reported by Connecticut hospitals declined in 2016, but sexual assaults more than doubled, according to a new state report. The Department of Public Health (DPH) report shows that hospitals reported a total of 431 medical errors in 2016, down about 5 percent from 456 in 2015. But there were 24 reports of sexual abuse or assault on a patient or staff member within or on the grounds of a health care setting last year, up 140 percent from 10 cases in 2015, the report said. A majority—22 cases—happened at acute care hospitals. St.
