The results of the study showed that patients admitted to the study service were younger, had lower comor-bidity scores, and were more likely to be admitted at night. After adjustment forthese and other factors, and for clustering by attending physician, total cost of care was marginally lower on the study service (adjusted costs 3.9% lower; 95%confidence interval [CI] 27.5% to 20.3%), but LOS was not significantly different(adjusted LOS 5.0% higher; 95% CI, 20.4% to 110%) as compared with housestaff ser vices. No difference was seen in inpatient mortality, ICU transfers, read-missions, or patient satisfaction.

The patients in the study consisted of a total of 5194 consecutive patients admitted to the general medicalservice from July 2005 to June 2006, including 992 patients on the physician as-sistant/hospitalist service and 4202 patients on a traditional house staff service.
