Background: Although high-quality treatment and modern hypertension clinical practice guidelines have been developed worldwide, the outcomes of patients with hypertension in Thailand are not optimal. Implementing a person-centred and integrated health services model to improve hypertension management, such as a community-based intervention, is challenging for healthcare providers in Thailand. Design: An observational study of a community-based intervention. Methods: The study comprised residents in 17 villages in one province of Thailand. A sample of 156 participants was allocated into the intervention and the control groups. Inclusion criteria were people aged 60 years or older diagnosed with hypertension. Exclusion criteria included the latest record of extreme hypertension and having a documented history of cognitive impairment. The intervention group received the 4-week community-based intervention programme. Multiple linear regression was applied to predict the adherence status at each phase. Multiple logistic regression was then implemented to predict influencing factors between the groups. Results: Patients who received the intervention had significantly lower adherence scores (reflecting a higher level of adherence) at 3 and 6 months after intervention by 1.66 and 1.45 times, respectively, when adjusting for other variables. After 6 months, the intervention was associated with a significant improvement in adherence when adjusting for other variables. Conclusion: This study provides evidence to support the use of community-based interventions as an effective adjunct to hospital-based care of hypertension patients in Thailand. Implications for practice: Understanding factors between health outcomes and social determinants of health is crucial for informing the development of culturally appropriate interventions.
