Objective This paper aims to explore patient satisfaction with mobile medical payments in ethnic minority areas and its influencing factors.Methods From May to August 2023,565 ethnic minority patients from 6 villages in 4 ethnic minority autonomous counties in Dehong Prefecture and Pu'er City,Yunnan Province,were selected as research subjects,and 186 Han patients in Kunming were selected as controls.The general information questionnaire,the mobile medical payment will-ingness and attitude survey scale,and the medical cost mobile payment satisfaction survey scale were used to investigate their sat-isfaction with actual situation of medical mobile payment.Additionally,this paper discussed influencing factors affecting satisfac-tion.Results The ethnic minority patients exhibited a significantly lower level of satisfaction compared to the Han patients(39.65±10.43 vs.49.54±7.88,P＜0.05).ethnic minority patients scored significantly lower on the dimensions of satisfac-tion,such as perceived safety,ease of use and usefulness of mobile medical payment compared to the group of Han patients(all P＜0.05).Additionally,they ethnic minority patients showed significantly lower level of willingness and attitude to use mobile medical payment compared to the group of Han patients(P＜0.05).The main factors influencing the significant difference in satisfaction with mobile medical payment were ethnic group,number of hospital visits in previous year,first-time use of mobile medical payment,and educational background(P＜0.05).Conclusion Ethnic minority patients have a low perception of secur-ity,ease of use,and usefulness of mobile medical payments,as well as a low willingness and characteristics for mobile medical payment.Therefore it is necessary to further enhance their experience and satisfaction.In the development of mobile medical pay-ment services hospitals should fully consider the current situation of"illiteracy""semi-illiteracy"and"lack of resources"in re-mote ethnic areas.They should actively develop service platforms and applications suitable for mobile medical payment in ethnic minority areas to continuously enhance service efficiency and quality.
