Abstract

Background: Faecal Immunochemical Testing (FIT) usage for symptomatic patients is increasing, but variations in use by sociodemographics are unknown. We introduced FIT for symptomatic patients in November 2017. Aim: Identify whether demographics, ethnicity or social deprivation affect FIT return in symptomatic patients. Design and Setting: FIT was introduced as a triage tool in Primary Care and was mandated for all colorectal referrals (except rectal bleeding/mass) to secondary care. FIT was used, alongside full blood count and ferritin, to stratify colorectal cancer risk. Method: All referrals November 2017-December 2021 were retrospectively reviewed. Sociodemographic factors affecting FIT return were analysed by multivariate logistic regression. Results: 35,289 patients returned their index FIT (90.7%), 3631 (9.3%) did not. On multivariate analysis, males were less likely to return FIT (OR 1.11, 95%CI 1.03-1.19). Patients over 65 were more likely to return FIT (OR 0.78 for non-return, 95%CI 0.72-0.83). Unreturned FIT was more than doubled in the most compared to the least deprived (OR 2.20, 95%CI 1.99-2.43). Patients from Asian (OR 1.82, 95%CI 1.58-2.10), Black (OR 1.21, 95%CI 0.98-1.49) and Mixed/Other ethnic groups (OR 1.29, 95%CI 1.05-1.59) were more likely to not return FIT compared to White ethnicity. 599 colorectal cancers were detected (1.5%), 561 in those who returned a first FIT request, 38 in those who did not. Conclusion: FIT return in those suspected of having colorectal cancer varies by gender, age, ethnicity, and socioeconomic deprivation. Strategies to mitigate effects on FIT return and colorectal cancer detection should be considered as FIT usage expands.
