Incidents of pressure ulcers, wrong-site surgeries and other surgical errors reported by Connecticut hospitals have increased in the last five years, despite myriad efforts to curb them, a new state report shows.

At the same time, state health department investigations of many hospital adverse events, such as patient injuries from falls, perforations resulting in disability, and death or serious injury due to surgery, have been rare, data in the report shows.
