In response to a Las Vegas Sun investigation of hospital care, St. Rose Dominican Hospitals officials have pledged to make public their internal quality measures — and challenged other local hospitals to do the same. The Sun investigation, based on hospital billing data on file with the state, identified 969 instances in 2008 and 2009 in which patients suffered preventable injuries, infections or other harm in Las Vegas hospitals. St. Rose CEO Rod Davis is the first hospital executive to come out in favor of greater transparency. In a meeting last week he pledged to share with the Sun and post on his hospitals’ website cases of preventable harm — known as “adverse” events — that occur at the three St. Rose Dominican Hospitals: Siena, Rose de Lima and San Martin. St. Rose will also publicize the so-called sentinel events it reports to the state. Sentinel events are unexpected injuries that require corrective plans. No facility in the state has ever made them public.
