What happens after an NHS Health Check? A survey and realist review

Abstract

Background The National Health Service Health Check in England aims to provide adults aged 40 to 74 with an assessment of their risk of developing cardiovascular disease and to offer advice to help manage and reduce this risk. The programme is commissioned by local authorities and delivered by a range of providers in different settings, although primarily in general practices. This project focused on variation in the advice, onward referrals and prescriptions offered to attendees following their health check. Objectives (1) Map recent programme delivery across England via a survey of local authorities; (2) conduct a realist review to enable understanding of how the National Health Service Health Check programme works in different settings, for different groups; (3) provide recommendations to improve delivery. Design Survey of local authorities and realist review of the literature. Review methods Realist review is a theory-driven, interpretive approach to evidence synthesis that seeks to explain why, when and for whom outcomes occur. We gathered published research and grey literature (including local evaluation documents and conference materials) via searching and supplementary methods. Extracted data were synthesised using a realist logic of analysis to develop an understanding of important contexts that affect the delivery of National Health Service Health Checks, and underlying mechanisms that produce outcomes related to our project focus. Results Our findings highlight the variation in National Health Service Health Check delivery models across England. Commissioners, providers and attendees understand the programme’s purpose in different ways. When understood primarily as an opportunity to screen for disease, responsibility for delivery and outcomes rests with primary care, and there is an emphasis on volume of checks delivered, gathering essential data and communicating risk. When understood as an opportunity to prompt and support behaviour change, more emphasis is placed on delivery of advice and referrals to ‘lifestyle services’. Practical constraints limit what can be delivered within the programme’s remit. Public health funding restricts delivery options and links with onward services, while providers may struggle to deliver effective checks when faced with competing priorities. Attendees’ responses to the programme are affected by features of delivery models and the constraints they face within their own lives. Limitations Survey response rate lower than anticipated; review findings limited by the availability and quality of the literature. Conclusions and implications The purpose and remit of the National Health Service Health Check programme should be clarified, considering prevailing attitudes about its value (especially among providers) and what can be delivered within existing resources. Some variation in delivery is likely to be appropriate to meet local population needs, but lack of clarity for the programme contributes to a ‘postcode lottery’ effect in the support offered to attendees after a check. Our findings raise important questions about whether the programme itself and services that it may feed into are adequately resourced to achieve positive outcomes for attendees, and whether current delivery models may produce inequitable outcomes. Future work Policy-makers and commissioners should consider the implications of the findings of this project; future research should address the relative scarcity of studies focused on the end of the National Health Service Health Check pathway.
