Compliance with colorectal cancer (CRC) screening in Canada is low. The aim of the present survey was to determine whether Canadian physicians older than 50 years were pursuing colon cancer screening. Specifically, physicians were asked to identify their modality of choice and identify their barriers to screening.
Surveys were mailed to members, older than 50 years, of the Canadian Association of Gastroenterology, the Society of Obstetricians and Gynaecologists of Canada, the Canadian Society of Internal Medicine, the Canadian Psychiatric Association and the Canadian Association of Radiologists.
Of 2,807 surveys, 46% were returned. Screening for CRC was reported by 53% of respondents. The Canadian Association of Radiologists members (61%) and the Canadian Association of Gastroenterology members (61%) were more likely to be screened than other specialties (P<0.01 and P<0.05, respectively). Members of the Society of Obstetricians and Gynaecologists of Canada (44%) were least likely to be screened (P<0.001). Men (P<0.001) and Ontario physicians (P<0.01) were more likely to be screened than women and Canadian physicians from other provinces, respectively. Colonoscopy (56%) was the most common screening modality used, followed by fecal occult blood testing (27%). Respondents who had not been screened cited a lack of personal time (47%) and insufficient data to warrant screening (14%).
More than one-half of all respondents were screened for CRC. Colonoscopy is the most common screening modality used. Lack of time is the most common reason cited for not participating in CRC screening.
加拿大对结直肠癌（CRC）筛查的依从性较低。本次调查的目的是确定50岁以上的加拿大医生是否进行结肠癌筛查。具体而言，要求医生确定他们选择的筛查方式，并找出他们进行筛查的障碍。
向加拿大胃肠病学协会、加拿大妇产科学会、加拿大内科医学会、加拿大精神科协会和加拿大放射学会50岁以上的会员邮寄调查问卷。
在2807份调查问卷中，46%被返还。53%的受访者报告进行了CRC筛查。与其他专业相比，加拿大放射学会会员（61%）和加拿大胃肠病学协会会员（61%）接受筛查的可能性更高（分别为P<0.01和P<0.05）。加拿大妇产科学会会员（44%）接受筛查的可能性最低（P<0.001）。男性（P<0.001）和安大略省的医生（P<0.01）接受筛查的可能性分别高于女性和来自其他省份的加拿大医生。结肠镜检查（56%）是最常用的筛查方式，其次是粪便潜血检测（27%）。未接受筛查的受访者提到缺乏个人时间（47%）和缺乏足够的数据支持筛查（14%）。
超过一半的受访者接受了CRC筛查。结肠镜检查是最常用的筛查方式。缺乏时间是未参加CRC筛查最常提到的原因。
