The study explored patient experiences of the Call for a Kit (CFAK) intervention, a community-based initiative designed to improve bowel cancer screening uptake and examined the mechanisms that may support participation among non-responders.

A convergent parallel mixed-methods design was employed, combining quantitative surveys and qualitative interviews.

The evaluation was conducted in general practices across Lancashire and South Cumbria, Northwest England, where CFAK clinics were delivered by an external health promotion team based within the Community Voluntary Services. These clinics target practices with low screening uptake.

A total of 113 CFAK attendees aged 54 and above, and who had missed their most recent screening invitation, completed a patient experience survey. 12 participants were purposively sampled for follow-up interviews.

Statistical analyses examined associations between patient experience and screening behaviours, including kit ordering and intention to complete the screening kit. Thematic analysis explored barriers and facilitators to participation, as well as experiences of CFAK clinics.

Patient experience scores were significantly higher among women than men and were positively associated with intention to complete the kit, though not with kit ordering. Qualitative findings indicated that CFAK addressed key barriers such as low awareness, confusion and emotional discomfort by providing personalised education, reassurance and culturally sensitive support. Participants particularly valued the relational aspects of the intervention, including the face-to-face delivery and communication in preferred languages.

CFAK clinics appear to enhance psychological capability and motivation for bowel screening by offering tailored, inclusive and supportive care. These findings highlight the value of patient-centred approaches in addressing inequalities in cancer screening and offer insights for the design of future community-based interventions.

Primary care electronic health records provide a rich source of information for inequalities research. However, the reliability and validity of the research derived from these records depend on the completeness and resolution of the codelists (ie, collections of medical terms/codes) used to identify populations of interest. The aim of this project was to develop comprehensive codelists for identifying people from ethnic minority groups, people with learning disabilities (LDs), people with severe mental illness (SMI) and people who are transgender.

We followed a three-stage process to define and extract relevant codelists. First, groups of interest were defined a priori. Next, relevant clinical codes, relating to the groups, were identified by searching Clinical Practice Research Datalink (CPRD) publications, codelist repositories and the CPRD Code Browser. Relevant codelists were extracted and merged according to group, and duplicates were removed. Finally, the remaining codes were reviewed by two general practitioners (GPs).

The curated codelists were compared using a representative sample in the UK. The frequencies of individuals identified using the curated codelists were assessed and compared with widely used alternative codelists.

Comprehensiveness was assessed in a representative CPRD population of 10 966 759 people.

After removal of duplicates and GP review, codelists were finalised with 325 unique codes for ethnicity, 558 for LD, 499 for SMI and 38 for transgender. Compared with comparator codelists, an additional 48 017 (76.6%), 52 953 (68.9%) and 508 (36.9%) people with LD, SMI or transgender code were identified. The proportions identified for ethnicity, meanwhile, were consistent with expectations for the UK (eg, 6.50% Asian, 2.66% black and 1.44% mixed).

The curated codelists are more sensitive than those widely used in practice and research. Discrepancies between national estimates and primary care records suggest potential record/retention issues. Resolving these requires further investigation and could lead to improved data quality for research.
