PURPOSE: To determine the operational characteristics of radiology groups in the United States in 1992. MATERIALS AND METHODS: The American College of Radiology surveyed a stratified random sample of 695 radiology groups, including academic departments, units in multispecialty groups, and staff of government facilities. After intensive follow-up, a 69% response rate was achieved for in-scope groups. The responses were weighted to show what findings would have been if all radiology groups in the country had responded. RESULTS: Thirteen percent of groups practiced in a university or teaching hospital; 59%, in a nonprofit hospital; and 18%, in a proprietary hospital; 42% routinely read images obtained by other practices; and 15% were involved with mobile vans. Radiologists in diagnostic-only practices averaged 11,100 procedures per year per full-time equivalent. However, the average was about one-third lower in office-only practices and primarily academic practices. Most groups had no female radiologists. CONCLUSION: Workload data show a great deal of variability and means should not be taken as standards.
