Using physician work relative value units to profile surgical packages: methods and results for kidney transplant surgery.

Background: This investigation outlines an approach for using the physician work relative value units (RVUs) in the Medicare Fee Schedule (MFS) to profile physician clinical activities. These techniques were then used to profile the physician services associated with kidney transplant patients at Emory University System of Health Care.

Methods: All physician services associated with 179 patients who had kidney transplant surgery in 1993 were studied. By using billing data, physician work RVUs were assigned to each service and the results were analyzed by type of service and the hospital department providing the service for physician work RVUs and physician charges.

Results: A mean of 130.4 physician work RVUs were involved in the 179 episodes of care. Surgical services represented 48.7% of the physician work activity in the kidney transplant. Visit and consultative services make up the next highest share with 25.5% of the physician work RVUs, whereas anesthesia makes up 13.3% of physician work RVUs. Physician charges totaled $16,249 for kidney transplants in 1993 dollars. Surgical services accounted for 54.2% of physician charges connected with kidney transplants, whereas visits and consultative services represented 20.6% of physician charges.

Conclusions: Physician work RVUs in the MFS offer a unique and much needed perspective on physician clinical activities. Physician work RVUs are an important new tool for healthcare and researchers and their use needs to be more fully explored and benchmarks developed for all major medical and surgical services.
