Objective:To provide reference for the sustainable development of county medical communities through analyzing key issues in the construction of such communities in China.Methods:Such Database websites as CNKI, Wanfang Data and VIP Information were selected to retrieve journal papers and dissertations with the keywords of " county medical community" " county medical alliance" " county medical and health community" and " medical alliance" . The time period ranged from the establishment of the database to December 2021. Content analysis and social network analysis were used to classify and sort key issues of county medical community construction in the included literature, and the descriptive analysis was used for all the data.Results:274 literatures were obtained in this study, 82 high-frequency issues were extracted for the construction process of county medical communities. It was divided into 3 dimensions of service system, operation mechanism and fund guarantee, including 14 items of integration of resources, integrated management, resource intensification, information construction, medical services, medical quality, family doctors, public health, management system, personnel system, salary system, supervision mechanism, medical insurance fund and financial input. The results of social network analysis showed that the top three high-frequency issues of point centrality and intermediary centrality were lack of highly unified information exchange platform (107.00, 514.48), insufficient service capacity of primary medical institutions (61.00, 238.48) and lack of sustainable benefit distribution mechanism (45.00, 192.38).Conclusions:The construction of county medical community covered three aspects: medical service system, operation mechanism and fund guarantee.The shortage of primary medical service capacity, the lack of coordination of an information platform, the general shortage of essential drugs, the imperfect internal assessment and incentive system, the imperfect supervision system and the imperfect medical insurance supporting policy becomed the main roadblocks in building county medical communities in China. In order to promote the sustainable development of county medical community, the authors recommend to further upgrade the county integrated medical service system, perfect the operation mechanism, and strengthen the input into county health care.
