A new report says 72 people died in New Jersey hospitals last year as a result of preventable errors. That's 30 more than in 2006, but state health officials and patient advocates say the increase appears to be more the result of better reporting than worsening care. The state Department of Health and Senior Services released its third annual Patient Safety Act report on Wednesday. The Patient Safety Act requires hospitals to report surgical errors, medication errors, falls, bed sores and other incidents. Hospitals reported 456 such incidents for 2007, a number that has grown each year since the state began tracking the data in 2005. Falls and Pressure Ulcer events are the largest types of events reported.
