Calculation of relative weights for nuclear medicine procedures

Relative weights for nuclear medicine procedures have been assigned previously on the basis of subjective estimates of resources expended. Thus, ultimate values frequently have not reflected time and cost of personnel and equipment accurately. Based on computerized data collected on over 8000 patients, we have attempted to calculate relative weights more objectively by analyzing the following parameters: (a) physician time; (b) technologist time; (c) nurse (or aide) time; (d) equipment time and depreciation; and (e) radiopharmaceutical cost, or cost equivalent. Most major organ scans were found to have quite similar values whereas procedures with low ratings on previous value schedules were found to have high relative values when analyzed objectively. (U.S.)
