Background: The integration of medical and nursing has been gradually carried out in recent years, but the weak family pension and insufficient community pension at this stage are not enough to support the integration of medical and nursing in China. Therefore, it is of great significance to improve medical-nursing integrated services in pension agencies by investigating their current status. Objective: To explore the main problems of medical-nursing integrated services in private pension agencies through understanding their current situation, and provide countermeasures for optimizing the medical-nursing integrated services. Methods: We selected 6 pension agencies for investigation according to the combination mode of medical and nursing with stratified sampling method, then interviewed 6 managers from 6 private pension agencies with in-depth interview from December 2019 to January 2020, finally analyzed and summarized the interview data with the Colaizzi 7-step analysis method. Results: The main problems of medical-nursing integrated services in private pension agencies are lack of medical service standards, poor integration of medical and nursing, insufficient number and low quality of medical-nursing integrated service team, lack of policy support, single fund-raising channel for pension agencies and heavy financial burden of high service fee for the elderly. Conclusion: The countermeasures to solve the above problems are clarifying the goals of medical services, strengthening the construction of medical-nursing integrated service team, increasing policy support and investment, and accelerating the popularization of the long-term care insurance system.
