Abstract: OBJECTIVE: To examine racial differences in breast cancer screening in an HMO that provides screening at no cost. DESIGN: Retrospective cohort study of breast cancer screening among African-American and white women. Breast cancer screening information was extracted from computerized medical records. SETTING: A large HMO in New England. PATIENTS/PARTICIPANTS: White and African-American women (N = 2,072) enrolled for at least 10 years in the HMO. MAIN RESULTS: Primary care clinicians documented recommending a screening mammogram significantly more often for African Americans than whites (70% vs 64%; P <.001). During the 10-year period, on average, white women obtained more mammograms (4.49 vs 3.93; P <.0001) and clinical breast examinations (5.35 vs 4.92; P <.01) than African-American women. However, a woman's race was no longer a statistically significant predictor of breast cancer screening after adjustment for differences in age, estimated household income, estrogen use, and body mass index (adjusted number of mammograms, 4.47 vs 4.25, P =.17; and adjusted number of clinical breast examinations, 5.35 vs 5. 31, P =.87). CONCLUSIONS: In this HMO, African-American and white women obtained breast cancer screening at similar rates. Comparisons with national data showed much higher screening rates in this HMO for both white and African-American women.
