Bridging accessibility gaps in urban community-based basic older adult care: a comprehensive framework validated in Xi’an, China

This study introduces a novel accessibility evaluation framework tailored for basic older adult care services, addressing critical gaps in affordability, psychological care, and service responsiveness. Empirical results validate the framework's practicality and its alignment with the real-world conditions of urban aging societies. Furthermore, an innovative "Matching-Realization-Satisfaction" improvement pathway is proposed, offering actionable strategies to enhance accessibility and optimize service delivery. This framework serves as a replicable model for advancing equitable older adult care in rapidly aging urban communities.
