Work hours of residents in seven anesthesiology training programs

Medical educators and credentialing organizations recently have called attention to the long hours that some house staff are required to spend in the hospital during training. To determine the average duration of in-hospital work hours of anesthesiology residents, 148 residents at seven, university-affiliated training programs kept daily logs of their activities for one week. Residents in clinical anesthesia years 1, 2, and 3 spent an average of 66, 65, and 64 hours per week, respectively, in the hospital with a range of 43 to 104 hours per week. Although there was not a difference in in-hospital work time among years of training, there was a statistical difference between two of the seven programs studied. The largest portion of the in-hospital time was devoted to patient care activities in the operating room. Residents had time for educational activities, conferences, and reading while in the hospital. The overall work hours of the residents in the anesthesiology training programs included in this survey appeared to be within current guidelines.
