Procedures performed by family physicians, internists, and a Medex in a small group practice.

Encounter forms for all patient visits to a small group practice (two internists, three family physicians, and one Medex) were examined retrospectively for October 1979 and January, April, and July 1980. A total of 5,694 patient encounters (2,327 male, 3,367 female) were recorded during the four months studied. Diagnostic and therapeutic procedures were performed on 592 patients (9.6 percent), 321 male and 271 female. The family physicians performed fewer procedures on their patients (6.1, 7.5, and 8.6 percent of the total patients seen). The Medex did 18.4 percent of all office procedures for that time period. The ten most commonly performed procedures included electrocardiogram (ECG), rhythm strip or ambulatory ECG, splint application, suture removal, pulmonary function test, suturing, exercise treadmill test, wart removal, removal of skin lesion or punch biopsy, application or removal of plaster cast, and application of ace wrap, sling, or collar. The majority of the procedures performed by the family physicians were also done by the Medex; however, the diversity of the procedures performed by the family physicians was comparable with that of the internists. There were large economic differences between groups, with the internists having the highest total billings and the Medex the lowest average charge per procedure performed.
