ATTITUDES AND PRACTICES OF PRIMARY-CARE PHYSICIANS FOR PROSTATE-CANCER SCREENING

Prostate cancer screening with digital rectal examination (DRE) and pr ostate-specific antigen (PSA) is recommended by several professional o rganizations. Our objective was to assess the prostate cancer screenin g practices and attitudes reported by primary care physicians. We rand omly surveyed 454 Arizona primary care physicians, subsequently exclud ing 124 ineligible subjects. Overall, 141 of 329 eligible physicians c ompleted the survey (42.9%). Survey data included physician demographi cs, practice characteristics, screening and follow-up strategies, and attitudes toward screening. One hundred thirty-one physicians (93%) re ported screening asymptomatic men with DRE or PSA. Respondents general ly agreed that screening tests were accurate and that early detection was beneficial. Screening began at an average patient age of 45 years, though 7.8% of respondents began screening men younger than 40 years and 7.0% began screening men older than 50 years. PSA levels ranging f rom 3.9 to 40 ng/mL were considered abnormal, and 11.6% of respondents used a cutpoint higher than 10 ng/mL. Primary care physicians report a high rate of screening for prostate cancer and consider PSA and DRE accurate and useful tests. Screening practices, however, varied consid erably between physicians. The screening of younger men reported by pr actitioners would tend to increase the rate of false-positive tests, w hile using a high cutpoint for PSA and delaying screening beyond age 5 0 years would decrease the chance for early detection. These screening practices may increase health care costs without necessarily leading to improved health outcomes.
