AHRQ QIs In Action

The Johns Hopkins Hospital worked diligently to improve its performance for Postoperative Respiratory Failure (PSI 11). The effort started back in 2012 when only 30 percent were able to be removed from a ventilator within the desired timeframe. Today, nearly 60 percent of cardiac patients are taken off a ventilator in less than six hours following surgery.
