Objective:To study development problems and countermeasures of the health emergency management system in a city based on the grounded theory, for references on the construction of a new round of urban health emergency management system.Methods:From June 2020 to April 2021, 61 health emergency management personnel were selected using the objective sampling method from the municipal health commission and disease prevention and control center of a city, and from 11 district health bureaus and disease prevention and control centers, for semi-structured interviews. Grounded theory method was used to analyze the interview data.Results:288 concepts, 79 initial categories, 15 sub-categories, and 5 main categories were extracted from the interview materials. The urban health emergency management system was affected by a variety of constraints such as the weak construction of public health talent team, non-standard plan management, and limited information sharing. There was a fragmentation dilemma in structure and mechanism. It was necessary to strengthen policy support and emergency resource allocation to promote the reconstruction of the health emergency response system. Among them, policy support and emergency resource allocation were prerequisites, and the remodeling of health emergency system was the core process.Conclusions:There were problems such as insufficient resource supply and weak plan management in the construction of the city′s health emergency management system. We should establish a high-level driven policy system, strengthen the resource allocation of peacetime and wartime, and reshape the system and mechanism of coordination and integration, so as to continue to promote the continuous development of the health emergency management system.
