Practitioner perspectives on symptomatic faecal immunochemical testing: a qualitative interview study.

Background: Faecal Immunochemical Testing (FIT) is now core to the management of patients presenting in primary care with symptoms of possible colorectal cancer. Patients with a positive FIT (≥10μg Hb/g faeces) qualify for an urgent suspected cancer referral. FIT negative patients are typically managed in primary care or referred through routine pathways.

Aim: To examine practitioners' experiences of delivering symptomatic FIT, identifying perceived benefits, disbenefits and implementation issues, to inform potential future service improvements.

Design And Setting: Qualitative interview study with primary and secondary care health professionals, from across the UK, involved in delivering symptomatic FIT pathways.

Method: 30 semi-structured interviews with professionals from a range of specialties. An iterative topic guide informed interviews while allowing freedom to explore novel lines of inquiry. Pseudo-anonymised transcripts were coded and themes identified and developed.

Results: Symptomatic FIT was seen to be beneficial for increasing confidence in clinical decision-making and enriching the pool of patients being definitively investigated for colorectal neoplasia. There were varying views on the impact of symptomatic FIT on workload with the burden of additional workload generally seen to be located in primary care. Concerns about current practice included over-use of FIT, burden of investigations in patients with false-positive results and diagnostic delays, for both cancer and benign disease. Uncertainties existed around management of patients with rectal bleeding, appropriate strategies for safety-netting, and the value of repeat FIT.

Conclusion: Symptomatic FIT is largely seen as beneficial; however, health professionals would welcome further evidence and guidance around optimal application.
