Understanding willingness to access and experiences of NHS Stop Smoking Services: a qualitative systematic review with meta-aggregation synthesis.

Abstract Objectives NHS Stop Smoking Services (NHS-SSS) have been available in the United Kingdom (UK) since 2000. The service has proven to be effective, however uptake remains below aspirations. Understanding people's willingness and reasons for accessing and engaging with NHS-SSS is, therefore, important. The aim of this systematic review is to summarise the findings from qualitative research to understand people's views, perceptions and willingness to access NHS-SSS. Study design Qualitative systematic review with meta-aggregation synthesis. Methods Four electronic databases were searched for published qualitative studies, from Jan 2000 to Jan 2020. Following the screening, data extraction and quality assessment, data synthesis was conducted using meta-aggregation based on a patient-centred theoretical framework. We explored five ‘demand-side’ dimensions of service accessibility: the ability to perceive, seek, reach, pay and engage. Confidence in the synthesised findings relating to dependability and credibility was established using CONQual. Results Seventeen studies were included in the review. Twelve categories emerged, contributing to five synthesised statements, all with a CONQual rating of moderate confidence. Access and willingness to use NHS-SSS were found to be related to an individual's readiness to perceive that smoking is a problem for which a solution should be sought, their ability to seek a perceived effective treatment, to conveniently reach NHS-SSS, their perceptions around associated costs and tailoring care to improve engagement with individuals. Conclusions By using a theoretical framework incorporating healthcare access, this study provides policymakers valuable insights into people's willingness to access these services. Willingness to access NHS-SSS is multifaceted, nuanced and complex. Strategies to promote NHS-SSS uptake should include making services more attractive, relevant and responsive to individual perceptions around smoking and health. Given the higher prevalence of smoking in less affluent socioeconomic groups and in some ethnic minority groups, the importance of having a comprehensive and inclusive tobacco control policy, one that is linguistically and culturally sensitive, cannot be overstated.
