Retrospective coding of health care professional cancer screening behaviours and of real-world interventions designed to support them: Identifying recommendations to optimize intervention design.

Objectives: Screening can detect cancer earlier. Uptake of breast, cervical, and bowel cancer screening in England is below 75%. This study identifies the barriers and facilitators underpinning HCP screening behaviours which can support screening uptake, and reviews the design of real-world interventions targeting these, assessing for congruence between the two. The aim was to provide recommendations to improve the design of interventions.

Design And Methods: Barriers/facilitators were identified by a literature review and qualitatively coded using the theoretical domains framework (TDF). Interventions were identified by stakeholders and coded using the behaviour change wheel and the taxonomy of behaviour change techniques. Congruence was assessed through comparing the intervention designs with behavioural science experts' recommendations which link the TDF domains to intervention design. Recommendations targeted missed opportunities.

Results: Barriers/facilitators were extracted from 60 papers and most frequently coded to the TDF domains: environmental context and resources, knowledge and beliefs about consequences. Thirty-one interventions were identified, most frequently education, training or enablement functions, delivered via communication/marketing or service provision, and using BCTs designed to shape knowledge or highlight the consequences of or antecedents to screening. Intervention design was largely congruent with recommendations. However, there was less use of persuasion and modelling intervention functions and a reliance on BCTs such as providing instruction when other BCTs could be considered.

Conclusions: Recommendations include to consider a broader range of intervention functions and BCTs, particularly for training interventions which should make use of recommended BCTs such as 'graded tasks'.
