New Jersey’s 72 hospitals were less likely to make harmful mistakes compared to the rest of the nation’s hospitals in the majority of categories, according to the 2015 Hospital Performance Report. The state Department of Health relied on the most recent data, which for the state was 2012, and the nation, 2010. New Jersey’s hospital patients fared worse in two categories: the rate of blood clots post surgery, and rate of internal and eternal bleeding post-surgery. The lower the number, the better the outcome.
