A physician practice specializing in managing spine pathology is assessing the feasibility of adding a C-arm imaging unit. Implementation of C-arm producers would require hiring one or more radiology technicians to assist the physician. The practice manager, being familiar with forcasting techniques, has already developed a projection of annual C-arm procedures and would like to determine the target level of radiology FTEs ( full time equivalent) should the C-arm imaging unit be added at the table 7.2 out lines the forcasted volume of each procedure over an eight month period and estamated standard hours per procedure performed by a radiology tachnician. Indirect support time is 0.15 hours per procedure and constant time by all staff is two hours per day. The fringe benefit of allowance is 10 percent and practice utilization target is 85 percent . a. Calculate the standard hours per month b. Determine the required FTEs with fringe venegits C.Determine the sensitivity of required FTEs to a +/_10 percent change in procedure volumes.
