Accidental injuries of hospitalized patients. A prospective cohort study.

Eight hundred and six medical and surgical patients who were hospitalized via the emergency ward were followed over their entire impairment stays and rated in anterograde, double-blind fashion for inpatient incidents (falls, medication errors, other). Injuries were minor but affected 2.2% of admissions, a figure which is strikingly similar to studies in other hospitals. There was a statistical trend toward a higher-than-normal risk of hazardous in-hospital incidents for males age 20 to 40 admitted because of injury and for medically ill females over 60 years old.
