To explore the impact of family doctor contract service utilization on the choice of primary medical institutions among elderly patients with multimorbidity, and to provide a reference for improving the family doctor contract service system.
Based on the 2023 China Longitudinal Aging Social Survey (CLASS) data, propensity score matching was employed for analysis.
The utilization rate of contracted family doctor services was 23.8%, and the proportion of choosing primary healthcare institutions was 48.7%. The propensity score matching results showed that under the three matching methods—nearest neighbor matching, radius matching, and kernel matching—the average treatment effects on the treated (ATT) of contracted family doctor service utilization on the choice of primary healthcare institutions were 0.126 1, 0.128 6, and 0.117 9, respectively (all P<0.01). Heterogeneity analysis showed that the improvement effect of family doctor contract service utilization was stronger in urban participants than in rural participants, and the effect increased with the number of chronic diseases.
The utilization of contracted family doctor services significantly increases the likelihood that older adults with multimorbidity will choose primary healthcare institutions.Service provision should be precisely optimized according to the characteristics of different groups to further increase their utilization rate of primary healthcare services.
