Simulation of Performance Evaluation Model for Medical-Elderly Care Integrated Institutions Based on System Dynamics

Background: This paper takes the Chinese medical-elderly care integration model as the background, and aims to quantitatively explore the impact of different investment levels on the performance of the medical-elderly care integrated institutions. Methods Using the method of system dynamics, this paper divides the performance evaluation system of the medical-elderly care integrated institutions into three subsystems: input subsystems, output subsystems, and result subsystems, establishes a system dynamics model of performance evaluation for the medical-elderly care integrated institutions. Then set the integrated medical-elderly care service content, human input, material input, and policy support as the key elements, and finally use Vensim PLE software for simulation. Results The four key elements have different degrees of improvement in the performance of the medical-elderly care integrated institutions. Among them, the integrated medical-elderly care service content and the human input have the most significant impact on the performance of institutions. The model simulation results show that the system appears emergence phenomenon: the improvement rate of the combined effect of multiple factors is always higher than the sum of the improvement rates of the individual factors. Conclusion The integration of service content and resource investment in the combination of medical and elderly care can promote the performance of elderly care institutions effectively. Policy support plays an important role in promoting the development of institutional medical-care integration models. Managers should formulate the development strategy of elderly care institutions from a systematic perspective, and pay attention to the integration of "medical" and "elderly care" resources.
