With the aging process in China and the increasing demand for health services, county-level healthcare is facing significant challenges. In 2023, the National Health Commission and other departments jointly issued the Guiding Opinions on Comprehensively Promoting the Construction of Tight County Medical and Health Communities, which pointed out that carrying out the construction of tight county medical and health communities is an important measure to improve the efficiency of county medical and health resource allocation and utilization, promote the coordinated development and governance of medical insurance, medical care, and medicine, and promote the construction of a hierarchical diagnosis and treatment order. At the special seminar on "Social Evaluation Report on the Construction of County Medical Community" held in Beijing recently, multiple experts from "government, industry, academia, and research" believed that "medical prevention integration" is one of the effective means to solve problems and is also the key to comprehensively promoting the construction of a close county medical and health community (hereinafter referred to as the "County Medical Community"). How to do a good job in medical and preventive integration has attracted much attention. County hospitals are an important component of the national medical and health service system, undertaking the burden of disease diagnosis, treatment, and health management for nearly two-thirds of the population in China. Data shows that over 70% of diseases can be intervened through prevention. "In the integration of medical and preventive measures, the main responsibility and obligation of prevention lies with county-level hospitals. Because county-level hospitals target the widest population, tertiary hospitals should solve difficult diseases, and for county-level hospitals, prevention should be the main focus." said Zhang Baijun, Director of the Research Project Management Department of China Union Medical University. In the view of Wang Chun, CEO of Hamler Doctor Group, due to the fact that prevention often relies on government subsidies or a small portion of service fees, there is a difference in incentive mechanisms between medical and preventive measures. Therefore, currently, medical and preventive measures are only connected and have not truly integrated. "In the construction of the medical community, we need to encourage both high-quality treatment and prevention, so as to promote the integration of medicine and prevention with the guarantee of improving high-quality medical services." Faku County, Shenyang City, Liaoning Province, has a registered residence population of 420000, which is seriously aging, with about one elderly person over 65 years old in every five people. Starting from the grassroots level, Xingyingjie, Deputy County Mayor of Faku County, believes that the integration of medical and preventive measures requires multiple types of health management. Including health promotion and education, health screening, health follow-up, health intervention, etc. "Through the signing service of family doctors, Faku County has made family doctors and village doctors the health gatekeepers for every elderly person. We help cultivate good living habits for the people and the elderly, so that our elderly people try to avoid getting sick, get sick less, and avoid serious illnesses." Xing Yingjie said. The goal of building a medical community is to be within the county and not outside the county as much as possible; Outpatient patients should not be hospitalized; Those who can work at the grassroots level should not go to the county central hospital; What can be prevented is to minimize unnecessary hospitalization. Wang Zongfan, Director and Researcher of the Medical Insurance Research Office of the Chinese Academy of Labor and Social Security Sciences, said, "Connecting this link will improve the efficiency of the entire medical system or health service system, as well as the efficiency of the entire medical insurance fund utilization." The medical reform has three foundations: basic protection, strengthening grassroots, and establishing mechanisms, among which strengthening grassroots is extremely important. "County hospitals are the leading healthcare providers in China, undertaking the tasks of grassroots healthcare and prevention. Accelerating the reform and development of city and county hospitals and focusing on improving the level of medical diagnosis and treatment in county hospitals is of great significance."
