We explored whether African-American (AA) primary care physicians (PCPs) have different prostate cancer screening practices compared to non-AA PCPs, after adjustment for potential confounding factors such as the proportion of AA patients in PCP practices.


We used SAS/SUDAAN to compare weighted responses from AA PCPs (n = 604) with those from non-AA PCPs (n = 647) in the 2007-2008 National Survey of Primary Care Physician Practices Regarding Prostate Cancer Screening. We used multivariate logistic regression to calculate the weighted odds ratios (OR) and 95% confidence intervals (CI).


We found that AA PCPs had higher odds of working in practices with above-the-median (≥ 21%) proportions of AA male patients (OR, 9.02; 95% CI: 5.85-13.91). A higher proportion of AA PCPs (53.5%; 95% CI: 49.5-57.4) reported an above-the-median proportion (≥ 91%) of PSA testing during health maintenance exams as compared to non-AA PCPs (39.4%; 95% CI: 35.5-43.4; P < 0.0002). After adjusting for the proportion of AA patients and other factors, we found that AA PCPs had higher odds of using PSA tests to screen men (OR, 1.74; 95% CI: 1.11-2.73).


This study quantifies the magnitude of the differences reported in previous focus group studies. Our results may be helpful in hypothesis generation and in planning future research studies.
