7.2 A physician practice specializing in managing spine pathology is assessing the feasibility of adding a C-arm imaging unit. Implementation of C-arm procedures would require hiring one or more radiology technicians to assist the physician. The practice manager, being familiar with forecasting techniques, has already developed a projection of annual C-arm procedures, and would like to determine the target level of radiology FTEs should the C-arm imaging unit be added at the practice. Table EX 7.2 outlines the forecasted volume of each procedure over an eight-month period and estimated standard hours per procedure performed by a radiology technician. Indirect support time is 0.15 hours per procedure, and constant time by all staff is two hours per day. The fringe benefit allowance is 10 percent and the practice utilization target is 85 percent.
