Knowledge and practice of physicians regarding colorectal cancer screening

INTRODUCTION: Despite the high prevalence and high rates of mortality of colorectal cancer, it is likely to be a secondary prevention disease due to the presentation of characteristics that are ideal for a successful screening program, with a proven positive impact on its outcome. OBJECTIVE: To describe the knowledge and practice of physicians concerning screening tests for the prevention of colorectal cancer. METHODS: Cross-sectional study carried out between November 2011 and February 2012, through a questionnaire administered to 83 physicians who assist adult patients at the University Hospital of Universidade Luterana do Brasil and at basic health units of Canoas, Rio Grande do Sul, Brazil. RESULTS: From the number of physicians participating in the survey, only 35 (42.0%) reported prescribing tests for colorectal cancer screening. Out of these, only 21 used the screening on patients aged 50 years old or more, as recommended by the guidelines. Only 65.0% of the physicians reported investigating family history of colorectal cancer, and surgical experts were the ones who least investigated this risk factor (p=0.005), when compared with clinical and gynecology specialties. CONCLUSIONS: The number of physicians who reported ordering tests for the prevention of colorectal cancer is still low, and their knowledge regarding the recommendations of the guidelines is very limited. The results indicate the immediate need for investment in professional formation and medical staff training concerning preventive measures for colorectal cancer.
