OBJECTIVE. We sought to determine whether hospitalists specifically reduce inpatient radiologic testing and radiology costs, which to our knowledge has not previously been studied. We examined the number of radiologic studies ordered, total cost of radiology utilization, cost per patient, mean length of stay, and readmission rates for hospitalists and nonhospitalists across the top-10 discharge diagnosis related groups for hospitalists from October 2000 to September 2001.

CONCLUSION. We found no decreases in the utilization of radiology resources by hospitalists. Given the increasing volume and importance of radiology in clinical decision making, there will be increased pressure to justify the costs of these studies. We believe that more data should be collected about the use of radiology resources.

Keywords: diagnostic imaging • health care costs • hospitalist • imaging resources • radiology practice • radiology utilization • research
