Specialists’ Perceptions of Hereditary Colorectal Cancer Screening in Newfoundland and Labrador

Purpose: Colorectal cancer (crc) screening is particularly valuable in Newfoundland and Labrador (NL), where a substantial proportion of crc cases have a hereditary link. We examined the perceptions of gastroenterologists and general surgeons with respect to screening practices for patients with hereditary crc. Methods: We surveyed all gastroenterologists and general surgeons in NL to determine demographic and professional practice characteristics and screening knowledge, practices, and attitudes for four groups of patients with hereditary crc. Results: Of the 43 eligible physicians, 36 (83.7%) responded. Most of the physicians surveyed knew the correct age to start screening, preferred screening by colonoscopy, had a systematic means in their own practice of prioritizing patients for screening, and felt that family doctors or patients (or both) should be responsible for monitoring screening compliance. Most physicians reported that patients with hereditary nonpolyposis crc and familial adenomatous polyposis waited 3 months for screening; patients with a family history of crc or adenomatous polyp waited 6 months or longer. Although respondents agreed on the need for a province-wide crc registry [4.36 on a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree)], they disagreed that wait times were reasonable (2.81) and that other health professionals should perform colonoscopies (2.86). They were equivocal about the need for centralized bookings (3.25) and about whether genetic testing is useful for prioritizing patients (3.25). Conclusions: Gastroenterologists and general surgeons in NL were knowledgeable about screening, but had varying opinions about individual roles in screening, wait times, and the means for prioritizing and providing screening for patients with hereditary crc.
