Our goal was to evaluate trends in the use of radiology with inpatients in the 10-year period of 1984-1993.
MATERIALS AND METHODS
We retrospectively reviewed administrative data from a 751-bed, tertiary care hospital between October 1,1983, and September 30,1993 (fiscal years 1984-1993).
We coded each study by imaging technique : CT.
MR imaging, sonography, nuclear medicine, or conventional studies (plain films and fluoroscopy).
Echocardiography. cardiac catheterization, and angioplasty procedures were omitted.
The number of admissions per year was adjusted for severity of disease (case-mix-adjusted admission [CMA]). We used relative value units to evaluate workload changes during the study period.
We assessed significance of trends using linear regression analysis.
The total number of imaging studies per CMA decreased during the study period (p=0001).
This was due to a decrease in the number of conventional studies (p=0001) and sonograms per CMA (p=02). despite significant increases in the numbers of CT (p=005) and MR imaging (p=0001) studies per CMA.
No significant change existed in the number of nuclear medicine studies per CMA (p=11).
The global, professional, and technical relative value units per CMA rose during the latter half of the study. (...)
