Effective chronic disease management requires the active participation of patients, communities, and physicians. We examined the impact of the CRMHDP on healthcare use and health outcomes in a population-based PS matched retrospective cohort study over eight years.


We matched a CRMHDP group (n = 46,865) and a control group (n = 93,730) against healthcare utilisation and conducted difference-in-differences estimations. For the health outcome analysis, the intervention group (n = 27,242) and control group (n = 54,484) were analysed using the Kaplan-Meier method and Cox proportional hazard regression.


The difference-in-differences estimation of the average annual clinic visits per person and the average annual days covered were 1.26 (95% confidence interval, 1.13-1.39) and 22.97 (95% CI, 20.91-25.03), respectively, between the intervention and control groups. The adjusted hazard ratio for death in the intervention group, compared to the control group, was 0.90 (95% CI, 0.86-0.93). For stroke and chronic renal failure, the adjusted hazard ratios for the intervention group compared to the control group were 0.94 (95% CI, 0.88-0.99) and 0.80 (95% CI 0.73-0.89), respectively.


Our study suggests that for effective chronic disease management both elderly patients and physicians need to be motivated by community support.
