Abstract: Objective To investigate the status,experience,and training needs of epidemiological investigation and risk assessment capacities of infection prevention and control practitioners （IPCP） in Shanghai hospitals,in order to provide a basis for improving the epidemiological investigation,handling,and risk assessment capacities of IPCP in the future,exploring the construction of infection control talent team in medical institutions,and improving the reserve of infectious disease emergency response capacity of medical institutions. Method From September to November 2023,a cross-sectional questionnaire survey was conducted on a total of 354 IPCP in Shanghai,using convenient sampling. Results The score of epidemiological investigation and risk assessment capacities of IPCP in Shanghai was （187.82±27.35）,which was at the upper middle level. The capacity score of IPCP in tertiary hospitals was higher than that of non-tertiary hospitals,and the capacity scores of IPCP with experience in emergency response to infectious diseases,emergency rescue,emergency drills,and risk assessment training were higher than those without relevant experience （P<0.05 or P<0.01）. Among the survey subjects,79.94% expressed their willingness or very willingness to participate in epidemiological investigation and risk assessment training,and the top three training needs were emergency response plan and drill （93.22%）,basic knowledge of infectious diseases （83.33%）,and public health response （81.36%）. Conclusions The epidemiological investigation and risk assessment capacities of IPCP in Shanghai are generally robust,but the individual capacity levels vary greatly. So it is possible to strengthen training for weak links,comprehensively improve the epidemiological investigation and risk assessment capacities of the infection control talent team,and effectively build emergency response capacity reserves.
