Changes in the health care system have led to reduced availability of surgical residents to function as house officers in teaching hospitals. The purpose of this cross-sectional study was to assess the level of satisfaction of patients, physicians and nurses, and ancillary providers with the care provided by the midlevel providers (MLPs) who are utilized as house officers in a Level I trauma service. This type of care model is unusual because the trauma service no longer utilizes surgical residents to provide trauma coverage.
