The health effects of regulations restricting housestaff work hours to 75 hours per week are largely unknown.
The authors measured inpatient mortality of 1 268 738 patients admitted to 551 hospitals with medical diagnoses and 243 207 patients admitted for surgical diagnoses before and after 2003, when the work-hour regulation took effect. After 2003, the mortality rate for medical patients—but not surgical patients—decreased more in teaching hospitals than nonteaching hospitals.
The authors classified a hospital as “teaching” if it had a residency program; however, some teaching hospitals have nonteaching patients.
Limiting residents' work hours was associated with lower in-hospital mortality rates for medical patients in teaching hospitals.
