Background At present,the development of community health service and general practice in China has entered a special period in which rapid development coexists with bottlenecks.The impact of scientific research on community health service centers has been paid more attention.However,the existing empirical research on scientific research capacity evaluation lacks scientific and systematic studies.This study focused on the change of research capacity,realistic demand and policy orientation.Objective To construct a ranking of scientific research capacity of community health service centers in 2019 to reflect their changes and current situation in China in recent years.Methods From December 2018 to March 2019,we searched both Chinese and English database platforms,using keywords related to community health centers such as “community” “community health center” and so on.On the basis of outcome variables quantifying the impact of the articles, data mining and data cleaning, we developed the indicators measuring research findings of these community health centers, and by which we screened the initial sample for the 2019 evaluation. Then, we contacted some regional health commissions and primary care associations or institutions to conduct a questionnaire survey among 673 community health centers in the initial sample who volunteered,and 500 of them returning responsive questionnaires were determined as the final sample.Analytic hierarchy process was used to construct the evaluation system,from four aspects of scientific research input,scientific research output,scientific research management and scientific research efficiency,so as to obtain the ranking of scientific research capacity of community health service centers in China.Results In 2019,more than 70% of the top 100 community health service centers in the ranking of scientific research capacity were located in Jiangsu,Zhejiang and Shanghai.Per capita research funding and the number of papers published have increased significantly compared with those in last year.The three most progressive community health service centers were located in Shanghai.Conclusion The ranking of scientific research capacity of community health service centers has played a positive role in guidance,but there is a huge gap between regions.The evaluation system used in this study has a high theoretical and practical significance.
