As an important part of China′s multi-level medical insurance system, commercial health insurance has developed rapidly in recent years, but its guarantee level is still limited, and its role in the multi-level medical insurance system is not fully played. Huimin Insurance, as a new public private partnership health insurance, takes into account the dual characteristics of commercial operation and inclusive protection, and provides an important supplement to meet the needs of the masses for multi-level protection, alleviate the economic burden of serious diseases, and promote the innovation and development of the pharmaceutical industry. The author systematically analyzed the characteristics of social and commercial integration in the development of Huimin Insurance in China from the aspects of value-oriented mechanism, policy complementary mechanism and operation support mechanism, and analyzed the problems of in the current development process of Huimin Insurance based on the holistic governance framework of multi-level medical security system in three dimensions of " hierarchy-institutional-tool". It is suggested that the functional positioning of multiple subjects should be clarified, the ability of information integration should be enhanced, and the product design and serviceshould be optimized, so as to fully enlarge the supplementary security efficiency of Huimin Insurance, and explore a new path for the formation of a multi-level medical insurance system with Chinese characteristics.

Objective:To analyze the health development plans of the provinces in China during the " 14th Five-Year Plan" , and explore the key tasks, similarities and differences of health informatization construction in each province.Methods:Using the website of local people′s government and the official website of the provincial Health Commission, 27 copies of health development plans of various provinces during the " 14th Five-Year Plan" period were retrieved and collected from February 16 to June 5, 2022. The relevant statements of health information in the plan were extracted, content analysis was used to reveal the structural characteristics of the policy in the form of word frequency statistics, and discourse analysis was used to study the policy content.Results:The health information policies of 27 provinces during the " 14th Five-Year Plan" period could be summarized as 10 major themes, such as accelerating the construction of hierarchical diagnosis and treatment system, promoting the high-quality development of public hospitals, and deepening the reform of medical security system. The health information policy in the eastern, central and western regions was relatively clear, and there were certain differences in the construction points according to their own characteristics.Conclusions:During the " 14th Five-Year Plan" period, the policies of each province around the field of health information are well defined, and the core structure and content are similar. The distribution of key points in the eastern region is relatively balanced; the construction of health information in the central region is more prioritized and prominent; the construction of health information in the western region is focused on complementing the weak links and weaknesses.

With the explosive growth of " City-customized Medical Insurance" products, the voice of commercial health insurance needs medical insurance data support is increasing.The authors took " City-customized Medical Insurance" as the representative of commercial health insurance, analyzed the demands and motivations of stakeholders in medical insurance data sharing through the power-interest matrix model, and summarized the medical insurance data sharing path at the commercial insurance product design end and claim settlement end. It is suggested to strengthen the top-level design, build the implementation path of standardized sharing of medical insurance data and the operation mechanism of hospital data docking, to realize the value increment of all stakeholders.

Objective:To analyze the filing mechanism for cross provincial immediate reimbursement of medical insurance in China, so as to provide reference for optimizing the filing mechanism and improving the filing accessibility of insured personnel.Methods:Taking the filing policy of cross provincial immediate reimbursement of medical insurance in 2019 as the research object, on the basis of a comprehensive understanding of the national filing policy background, 90 coordinating regions in Zhejiang Province, Hubei Province and Ningxia Hui Autonomous Region were taken as survey samples to evaluate the relevant policies and extract key parameters, including filing identification methods, filing-related settlement benefits and filing ways. The parameters were compared and analyzed by using descriptive statistical methods.Results:The results of the survey showed that in terms of identity recognition methods, the provision of various supporting materials(residence permit, work certificate, etc.)was still the main way to carry out identity recognition for medical insured persons in different places.Filing-related reimbursement benefits were mainly adjusted by limiting the area of medical insurance treatment and adjusting the benefits parameters(reimbursement ratio). In terms of filing channels, 51(56.7%)sample co-ordination areas had realized at least one remote filing mode.Conclusions:The inclusiveness of filing identity verification mechanism for the floating population needs to be further improved, the filing-related treatment policies need to be further improved, and the convenience and standardization of filing channels need to be strengthened.

After recent years′ development, China′s Internet medical service and medical insurance policy system has begun to take shape, but it still needs to be further improved. By combing the connotation and mode of Internet medical services, the evolution of medical insurance payment system and the content of medical insurance payment policy in the United States, the authors put forward that China could further improve the medical insurance payment policy system of Internet medical care, strengthen the multi-point practice management of licensed doctors on the Internet, give full play to the role of commercial insurance in promoting Internet medical care, and rely on information technology means to improve the medical insurance supervision of Internet medical services, then promote the development and management of Internet medical insurance services in China.

Objective:To provide a reference for establishing the evaluation system of the implementation effect of cross provincial direct settlement policy.Methods:By referring to the public policy evaluation model and using the expert consultation method, the authors built an evaluation index system for the implementation effect of cross provincial direct settlement policy for urban and rural residents. The multi-attribute group decision-making analytic hierarchy process, Matlab software and Yaahp software, combined with Spearman correlation coefficient method, were used to cluster the expert opinions and further determine the weight of each element at different levels.Results:The evaluation index system of the implementation effect of direct settlement policy for urban and rural residents′ cross provincial medical insurance was constructed, including 3 first-class indicators, 9 second-class indicators and 20 third-class indicators, and the weight of each index was calculated.Conclusions:The designed index system is suitable for grasping the implementation level of the cross provincial direct settlement policy from a macro perspective, and find out the problems in the implementation process. Efforts should be made to refine the evaluation criteria of the indicators in the index system.

BACKGROUND: Low dose computed tomography (LDCT) for lung cancer screening is widely employed in China as a result of increasing cancer screening awareness. Although some pulmonary lesions detected by LDCT are cancerous, most of the pulmonary nodules are benign. It is important to make effective preoperative differentiation of pulmonary lesions and to obviate the need for surgery in some patients with benign disease. METHODS: From January 1, 2017 to December 31, 2018, patients in our institution with surgical pathology confirmed benign pulmonary lesions in which malignancy could not be excluded in preoperative assessment were enrolled in this study. Retrospective analysis of clinical data was conducted. RESULTS: 297 cases were collected in this study. Prevalence of benign disease in patients underwent resection for focal pulmonary lesions is 9.8% in our institution. In 197 patients (66.3%), pulmonary lesions were detected by LDCT screening. A total of 323 assessable pulmonary lesions were detected by chest CT. The average diameter of pulmonary lesions was (17.9±12.1) mm, and 91.0% of which were greater than or equal to 8 mm. Solid nodules accounted for 65.6% of these lesions. Imaging characteristics suggesting malignancy were common, including spicule sign (71/323, 22.0%), lobulation (94/323, 29.1%), pleural indentation (81/323, 25.1%), vascular convergence sign (130/323, 40.2%) and vacuole sign (23/323, 7.1%). 292 patients (98.3%) underwent video-assisted thoracoscopic surgery (VATS). Pulmonary wedge resection was performed in 232 cases (78.1%), segmental resection in 13 cases (4.4%) and lobotomy in 51 cases (17.2%). Surgical complications occurred in 4 patients (1.3%). The most frequent findings on surgical pathology analysis were: infectious lesions in 98 cases (33.0%), inflammatory nodules in 96 cases (32.3%), and hamartoma in 64 cases (21.5%). CONCLUSIONS Solid nodules accounted for most of these benign pulmonary lesions in which malignancy could not be excluded preoperatively, and imaging characteristics suggesting malignancy were common. VATS is an important biopsy method to identify etiology and pathology for lesions. The most frequent benign pulmonary diseases that are suspected to be malignant and underwent surgical resection are: infectious lesions, inflammatory nodules and hamartoma.
