Does housestaff discontinuity of care increase the risk for preventable adverse events?
OBJECTIVE: To study the relation between housestaff coverage schedules and the occurrence of preventable adverse events. DESIGN: Case-control study. SETTING: Urban teaching hospital. PATIENTS: All 3146 patients admitted to the medical service during a 4-month period. MEASUREMENTS: A previously tested confidential self-report system to identify adverse events, which were defined as unexpected complications of medical therapy that resulted in increased length of stay or disability at discharge. A panel of three board-certified internists confirmed events and evaluated preventability based on case summaries. Housestaff coverage was coded according to the day in the usual intern’s schedule and to cross-coverage status. Cross-coverage was defined as care by a house officer who was not the patient’s usual intern and not a member of the usual intern’s patient care team. Coverage for an adverse event was assigned according to who was covering during the proximate cause of that event. Clinical
