Colorectal cancer screening practices of primary care physicians in Washington State.

ABSTRACT

BACKGROUND: Colorectal cancer screening reduces death from colorectal cancer, but screening rates are low. While research has identified barriers to screening from the patient perspective, less research has addressed screening from the physician perspective. METHODS: The Washington Comprehensive Cancer Control Partnership conducted a survey of primary care physicians in Washington State to measure their knowledge, attitudes, and practices for colorectal cancer screening of average-risk patients. The survey was mailed to a simple random sample of 700 primary care physicians in Washington State. Sixty-nine percent of the eligible physicians in the sample participated. RESULTS: Most respondents (76%) recommended one or more colorectal cancer screening tests in agreement with American Cancer Society guidelines, and 93% perceived patient anxiety about colorectal cancer screening tests to be a significant barrier to screening. Ninety percent of physicians reported using the fecal occult blood test (FOBT) as a screening test, but most did not report performing any tracking or using any mechanism to encourage their patients to complete and return FOBT kits. CONCLUSIONS: These findings suggest three intervention approaches to increase colorectal cancer screening in primary care settings improve physicians' knowledge about current screening guidelines (especially appropriate age and screening intervals), encourage physicians to strongly recommend screening to patients, and help physicians adopt tracking systems to follow screening to completion.
