The effectiveness of interventions used to improve general health check uptake by the older adult population: a systematic review and meta-analysis

Abstract

Abstract As the population ages, promoting good health maintenance practices has become an important strategy in many health systems. Regular general health checks detect common diseases and empower older adults to monitor their physical health. Yet the service uptake rate is low. Previous reviews have identified intervention methods to improve the uptake rate, but the overall effectiveness of these interventions remains unclear. This review aims to determine the overall effectiveness of the interventions used to improve general health check uptake and identify the behavior change techniques used in these interventions. Literature searches were conducted in four electronic databases in August 2020 and updated in May 2021. Six randomized controlled trials were included in this review. Seven intervention types were identified, including enhanced invitation letters, telephone invitation, question-behavior-effect questionnaire, financial incentive, leaflet, pre-notification, and SMS reminder. Overall, the interventions are effective, with an odds ratio of 1.21, and a 95% confidence interval between 1.09–1.33. Fifteen behavior change techniques were identified using the Behaviour Change Technique Taxonomy (v1). The findings suggest that the current interventions implemented in invitation methods are effective in improving the general health check uptake rate, but there are still opportunities to further improve the uptake rate by considering other intervention types. Future studies could consider how other intervention types could be implemented alone or with the enhanced invitation methods to maximize the service uptake rate. The systematic review protocol is registered on PROSPERO (ref: CRD42021221041).
