Rectal bleeding in general practice patients.

With the high prevalence of rectal bleeding and low consultation rates for this problem there is potential to enhance the effectiveness of early detection of CRC through general practice based public health and education campaigns.

Abstract

OBJECTIVE: To determine the prevalence of observed rectal bleeding in general practice patients, the health seeking behaviour of those with rectal bleeding, and what rectal bleeding 'means' to patients in terms of perceived health risk. METHOD: Self administered questionnaire survey of general practice patients aged 50 years and over in northern Tasmania recruited as they visited their general practitioner (GP). RESULTS: The reported lifetime prevalence of rectal bleeding in our sample was 33% (299 of 903 respondents). It was more common in younger people, becoming less common with increasing age. Many respondents do not examine for bleeding. Only 45% of respondents with rectal bleeding consulted their GP about the most recent bleed. Patients were more likely to consult if they reported blood in the toilet pan and if they sought advice from a family member. There were significant differences between the meaning of bleeding for GP consulters and non consulters. This may have important implications for health education. CONCLUSION: Colorectal cancer (CRC) is a common problem managed by a combination of screening and case finding. With the high prevalence of rectal bleeding and low consultation rates for this problem there is potential to enhance the effectiveness of early detection of CRC through general practice based public health and education campaigns.
