OBJECTIVES: To investigate whether sending a family history questionnaire to patients prior to undergoing colonoscopy results in an increased availability of family history and better genetic counseling. METHODS: A questionnaire was mailed to patients before they underwent outpatient colonoscopy at a university hospital in 2013. These patients' additional characteristics and referral for genetic evaluation were retrieved from the electronic medical records. Patients undergoing inpatient coloboscopy, with confirmed hereditary colorectal cancer (CRC) or inflammatory bowel disease were excluded. All study patients from 2010 to 2013 were matched with the database of the genetics department to determine who consulted a geneticist. RESULTS: A total of 6163 patients underwent colonoscopy from 2010 to 2013. Of 1421 who underwent colonoscopy in 2013, 53 (3.7%) consulted a geneticist, while 75 (1.6%) of 4742 patients undergoing colonoscopy between 2010 and 2012 did so (P < 0.01). A total of 974 patients undergoing colonoscopy in 2013 were included to evaluate the completed questionnaire. Of these, 282 (29.0%) completed the questionnaire. Family history was not recorded in the electronic medical records of 393 (40.3%). In 129 (32.8%), family history was obtained from the completed questionnaire. In 2013, 49 (60.5%) out of 81 patients referred for genetic counseling were referred based on their family history. Eight (9.9%) patients were referred based on the completed questionnaire. CONCLUSION: Screening for hereditary CRC in a population undergoing outpatient colonoscopy with a questionnaire sent by mail resulted in an increased availability of family histories and genetic counseling.
