title: Colorectal cancer screening: practices and attitudes of gastroenterologists, internists and surgeons.
abstract: BACKGROUND
  The Canadian Task Force on Preventive Health Care has recommended the use of annual or biennial fecal occult blood testing (FOBT) and flexible sigmoidoscopy in the periodic health examination of asymptomatic people over 50 years of age. Therefore, we decided to ascertain the current colorectal cancer (CRC) screening practices and attitudes of surgeons, gastroenterologists and internists.
  
  
  METHODS
  In June 2002 (with a final mailing in December 2002), a questionnaire was sent to all gastroenterologists, internists and surgeons in Alberta. It included items on demographic and practice characteristics, CRC screening practices and opinions about CRC screening.
  
  
  RESULTS
  Responses were received from 42 gastroenterologists, 83 internists and 68 surgeons. Overall, 141 of 187 respondents (75.4%, 95% confidence interval [CI] 68.6%-81.4%) recommended that average-risk adults undergo CRC screening. Internists were less likely to recommend screening than either gastroenterologists or surgeons (95% CI for the difference 7.2%-32.8%). The most commonly recommended screening test was colonoscopy (70%), followed by FOBT (65%), flexible sigmoidoscopy (47%) and air-contrast barium enema (31%). Colonoscopy was the only test recommended by 7 (22.6%) of 33 gastroenterologists, 9 (16.4%) of 59 surgeons and 3 (6.1%) of 49 internists. Respondents were more likely to list barriers to the use of colonoscopy (mean 5 barriers) for screening than for either FOBT or flexible sigmoidoscopy (mean 2 barriers for both tests). Only 3 respondents indicated that they themselves would not undergo screening. Colonoscopy was the only screening test that 135 (70.0%) of the 193 would themselves undergo.
  
  
  CONCLUSIONS
  The majority of Alberta specialists recommend CRC screening for average-risk adults. Colonoscopy was the most commonly recommended test, despite the perception of more barriers to that technique and the 2001 guidelines prepared by the Canadian Task Force for Preventive Health Care, which did not support colonoscopy.
