Doctors and nurses who work U.S. emergency rooms do not have much confidence in their safety and worry about working conditions, according to the findings from a study funded by the federal Agency for Healthcare Research and Quality. The researchers surveyed 3,562 emergency medicine clinicians in 65 hospitals. The majority of those surveyed said their emergency departments consistently lack sufficient space to deliver patient care, with a third saying the number of patients consistently exceeds their capacity to provide safe care.
