Utilization of Body Computed Tomography Units

Abstract

Utilization and economic data from body computed tomography (BCT) units with more than 1 1/2 yr experience are compared to data in 1977. The average unit operates 52 h wk, examining 34 patients. Head studies constitute 55% of examinations, abdominal and pelvic 38%. The total technical cost of examining 35 patients/wk is approximately $384,000. Charges have been reduced since 1977 by approximately 5%; the average annual loss is about $77,000. Technical and professional charges are lower in high-volume institutions. Current Medicare maximum allowable charges are below BCT costs and charges. Only 17% of instillations meet the National Guidelines of 2,500 patient examinations/yr.
