Objective To investigate the status quo of medical service continuity in a regional medical consortium in Shanghai,analyze the influencing factors,and provide reference for further improving the vertically integrated medical health service system. Methods From April to May 2024,a questionnaire survey was conducted among 354 patients who had referral experience in the past two years,randomly selected from the regional medical consortium leading hospi-tal and three community health service centers in Shanghai. Single factor and multiple linear regression were used to ana-lyze the influencing factors. Results The total score of medical service continuity in a regional medical consortium was (51.74±7.93),the score of relationship continuity dimension was (26.10±4.13),the score of management continui-ty dimension was (12.95±2.24),and the score of information continuity dimension was (12.66±2.46). Whether there is an economic source was the influencing factor of the overall continuity of medical service,relationship continuity and management continuity (P<0.05). Conclusion The overall situation of medical service continuity in the regional medical consortium is good,but the relationship between the leading hospital and the patients needs to be improved,and the guarantee mechanism of drug continuity supply is not yet perfect,the transmission and sharing of diagnosis and treat-ment information of referral patients are limited,the experience of medical service continuity of low-income patients is poor,and the evaluation of medical service continuity of elderly patients is low.
