Taking 20 national-level policy documents related to integrated medical and child care services between 2019 and 2025 as the research objects, the latent Dirichlet allocation (LDA) model was used to extract themes, including childcare service provision and inclusive access, integrated medical and child care services, workforce development and capacity building, institutional mechanisms and comprehensive regulation, and family support and parenting empowerment. The policy modeling consistency (PMC) index model comprising 9 first-level variables and 44 second-level variables was then constructed for quantitative evaluation. The results showed that the average PMC index of the 20 policies was 6.12, with an overall good evaluation, with 10 good policies and 10 acceptable policies. Among the dimensions, policy quality, policy perspective, and policy target received relatively high scores of 0.99, 0.95 and 0.89, respectively, while policy nature, policy categories, and policy timeliness received relatively low scores of 0.53, 0.36 and 0.30, respectively. Policy attention was mainly focused on service supply, medical and child care, and regulatory standards, with insufficient emphasis on family support and technical empowerment. China's integrated medical and child care policies have formed a preliminary institutional framework, but still need further improvements in policy coordination, policy coverage balance, and multi-departmental collaboration. The findings suggest improving the policy design across the continuum, strengthening family support and technical empowerment, and establishing a more effective cross-departmental collaborative governance mechanism.
