Physician compliance with colorectal cancer screening (1978-1983): the impact of flexible sigmoidoscopy.

Physician compliance with widely recommended colorectal cancer screening methods was studied over a five-year period in a university-based family medicine residency program. Indicated examinations were being avoided in symptomatic as well as asymptomatic patients aged over 50 years. The introduction of flexible sigmoidoscopy created significant change in previously documented poor resident and faculty compliance. Baseline measurement of outcomes was noted by audit of 189 adult medical records (year 1). Educational reemphasis by lecture and intragroup commitment produced no change by the end of year 2 (n = 189). Introduction of the flexible sigmoidoscope yielded a sevenfold increase in physician compliance in year 3 (n = 192). This compliance increased as measured by chart audit in years 4 (n = 166) and 5 (n = 190). All audited groups were mutually exclusive. The documented diagnostic superiority of this instrument was readily obtainable by family physician faculty and residents in training. With Papanicolaou smear activity serving as a control group, the findings indicated a significant and sustained effect. Two additional primary care training programs were audited during the final year of the study period. These control audits revealed continued poor compliance with rigid sigmoidoscopy. The flexible sigmoidoscope is an important addition to the diagnostic and screening armamentarium of a family medicine residency program.
