Connecticut hospitals reported fewer numbers of patients killed or seriously injured by falls or perforations during surgery or suffering from severe pressure ulcers in 2014 than in 2013, but the incidence of such “adverse events” still remains higher than in 2012, a new state report shows. The report by the Department of Public Health (DPH) shows that the total number of hospital adverse events, or errors, dropped by 12 percent — from 534 in 2013, to 471 last year. Deaths or serious injuries from falls declined from 90 to 78; perforations during surgical procedures fell from 79 to 70; and life-threatening medication errors fell from six to one. The number of patients with serious pressure ulcers dropped from 277 to 245. Rates of all four of those incidents had climbed in 2013, in part because of an expansion of required reporting on pressure sores to include “unstageable” ulcers.
