This paper sought to determine the status of older Australians with regard to Bowel Cancer screening practices occurring outside of the National Bowel Cancer Screening Program.
A random sample of N=25,511 urban Australians aged 50 to 74 years received a questionnaire via mail asking questions relating to bowel screening. N=8,762 (34.3%) returned a completed questionnaire.
Approximately 33% (N=2863) of respondents indicated they had undergone colonoscopy in the preceding five years and 21% (N=1840) had used a Faecal Occult Blood Test (FOBT) in the preceding 12 months. Furthermore, 27% (N=497) of those who had completed an FOBT had also undergone colonoscopy.
A significant proportion of older Australians might be participating in bowel screening practices outside of the national program (NBCSP). Moreover, the proportion of individuals reporting use of both FOBT and endoscopic services is much higher than the positivity rate of FOBT. Large population FOBT screening programs, such as the NBCSP, that do not consider participation in screening external to the program may underestimate true population screening rates.
本文旨在确定澳大利亚老年人在国家肠癌筛查计划之外进行肠癌筛查的情况。
对25511名年龄在50至74岁的澳大利亚城市居民进行随机抽样，通过邮件向他们发放问卷，询问与肠道筛查相关的问题。8762人（34.3%）返回了完整的问卷。
约33%（2863人）的受访者表示在过去五年中接受过结肠镜检查，21%（1840人）在过去12个月中使用过粪便潜血试验（FOBT）。此外，完成FOBT检查的人中有27%（497人）也接受过结肠镜检查。
相当一部分澳大利亚老年人可能在国家计划（NBCSP）之外参与肠道筛查。此外，报告同时使用FOBT和内镜检查服务的个体比例远高于FOBT的阳性率。像NBCSP这样不考虑计划外筛查参与情况的大规模人群FOBT筛查计划，可能会低估实际的人群筛查率。
