biht-436	Zhang, Jing; Fan, Haitao	Optimization of Health Service Utilization Among Elderly People with Chronic Diseases in Rural Ethnic Minorities in Northwest Yunnan Using Graph Neural Networks 	2025	15	.pdf	application/pdf	9355	458	39	Based on the output results and graph structure indi- cators (such as node centrality and path connectivity), suggestions for precise allocation of regional health re- sources and dynamic optimization of service paths are proposed.27,28 The results reveal significant differences in the struc- ture and space of medical services for ethnic minorities in northwestern Yunnan. Table 2 presents the matching of different chronic dis- ease combinations in terms of medical service utilization, measuring the rationality of services through indicators such as the number of patients, expected frequency of vis- its, actual matching rate, and utilization intensity classifi- cation ratio.	cache/biht-436.pdf	txt/biht-436.txt
