Objective:To study the changes of the perception of drug welfare of chronic disease patients and their impact on health level under the centralized drug procurement policy.Methods:It conducted a questionnaire survey and empirical analysis on the perception of drug welfare and health status of chronic disease patients after the implementation of the centralized drug procurement policy;set up an ordered logit regression model to investigate the impact of the perception of drug welfare on the health level of chronic disease patients and influencing factors,and analyzed the heterogeneity for geographic areas,populations and chronic disease types.Results:After the implementation of the centralized drug procurement policy,the perception of drug welfare of chronic disease patients was significantly improved,including the reduction of drug burden,the decrease of drug price and the increase of drug accessibility.Moreover,the health status of chronic disease patients is significantly affected by the perceived drug affordability,and the policy has greatly improved the health of this group,but there is still inequality.Conclusion:The implementation of the centralized drug procurement policy has been effective,the state should strengthen the policy propaganda,optimize the procurement strategy,so as to further enhance the drug welfare of chronic disease patients and improve their health.

Objective:To study the impact of the national volume-based procurement policy on inpatient medical costs.Methods:Firstly,a descriptive analysis on the completion of the procurement volume of drugs in the hospital was carried out,and furthermore,using the data on the medical costs of inpatients before and after the implementation of the policy,conducted statistics on changes in the structure of patients'medical expenses.Taking the time of the first day of using the volume-based procurement drugs as the breakpoint,a sharp regression discontinuity model was constructed to compare the changes in the different categories of costs.Re-sults:There is still room for improvement in the use of volume-based procurement drugs in the hospital.After the use of those drugs,in addition to the cost of comprehensive services and consumables rose by 1.01 and 3.07 percentage points respectively,the rest of the categories of costs were on a downward trend,the per capita total medical costs and drug costs of inpatients fell by 644.58 yuan and 300.19 yuan respectively.In addition,the average hospital stay of patients decreased significantly after the implementation of the poli-cy.Conclusion:The national volume-based procurement policy has achieved certain results,but there is a need to set more reason-able procurement volume targets and to adjust cost control measures in a comprehensive manner to further optimize the structure of medical costs.

OBJECTIVE To provide reference for assessing and improving the emergency management capacity of generic drug quality and safety under the background of normalization of centralized procurement by constructing emergency response capacity assessment index system of China’s generic drug quality and safety. METHODS Based on theoretical research and literature analysis， the emergency response capacity assessment index system of generic drug quality and safety was formulated preliminarily； the Delphi method and hierarchical analysis method were used to determine the evaluation index system and calculate the weights. RESULTS The degree of experts’ enthusiasm， authority coefficient and the degree of experts’ coordination were relatively good in the two rounds of consultation. The assessment indicator system was finally constructed for emergency management capacity of generic drug quality and safety， including 4 first-level indicators （quality risk early warning capabilities， emergency preparedness capabilities， response and disposal capabilities， and emergency recovery capabilities）， 11 second-level indicators （ability to monitor and early warn of quality risks in the development and production process of generic drugs， emergency organization mechanism guarantee， disposal and recovery， etc.） and 75 third-level indicators （risk monitoring of raw material quality of generic drugs， consistency evaluation of quality and efficacy of generic drugs， and monitoring of profit margin risks and hidden dangers of generic drugs， etc.）. Among them， the weight of generic drug quality risk monitoring and early warning capacity was the highest among the first-level indicators （0.392 4）， the combined weight of generic drug R&D and production quality risk monitoring and early warning capacity was the highest among the second-level indicators （0.146 0）， and the combined weight of generic drug raw material quality risk monitoring was the highest among the third-level indicators （0.023 0）. CONCLUSIONS The emergency management capacity assessment index system of generic drug quality and safety constructed in this study is hierarchical， reasonably weighted， and has a certain degree of credibility， and it can be used as an effective tool for the management and decision-making of generic drug quality and safety emergency management capacity assessment in the context of the normalization of centralized procurement.

Objective:Clarify the correlation between the Centralized Drug Volume-based Purchasing Policy,changes in physical&mental health status,and health inequalities among the older adults,as well as exploring whether this correlation differs between urban and rural areas so as to determine the role played by the total cost of healthcare.Methods:Based on CFPS 2018 and 2020,DID and PSM-DID were used to verify the impact of the Centralized Drug Volume-based Purchasing Policy on physical&mental health status and health inequalities of the elderly in urban and rural China.Three-step method and Sobel test were used to verify the mediating effect of total medical costs.Results:The pilot effect of the Centralized Drug Volume-based Purchasing Policy was first realized among the urban elderly population,promoting their physical and mental health through the intermediary mechanism of reducing the total medical costs,but for the time being did not show a significant correlation with health inequalities within this group.Among the rural elderly population,none of the three dependent variables was significant(P＞0.1).Conclusion:The underlying logic of the Centralized Drug Volume-based Purchasing Policy is right,but its future reform should focus on the rural elderly group,and consider the fairness of the effect within the group and between urban and rural areas,so as to improve the health level of the whole society in the longer term.
