Understanding Patient Outmigration from the Patients’ and Providers’ Perspective: A System Dynamics Approach

Short Description: This presentation delves into our ongoing work on patient outmigration in South Korea. Outmigration, a characteristic phenomenon of the South Korean health system, refers to patients bypassing local hospitals and traveling further to Seoul (the capital city of South Korea) to receive treatment. To unravel the dynamic mechanisms driving outmigration, we designed a causal loop diagram which examined this phenomenon from the patients’ and providers’ perspective. At its simplest level, decrease in objective quality of the provincial hospitals induces the increase in outmigration through the decrease of perceived quality, which then results in quality deterioration by discouraging healthcare providers from working in provincial areas, forming a vicious cycle and reducing trust towards the healthcare system. An early stage of this model was presented at the Student-Organized Colloquium (SOC) of the International System Dynamics Conference (ISDC) in July 2023. Question(s) for the Audience: I seek general feedback on each aspect of the causal loop diagram. I would also like to get insights on what to do next in order to continuously develop the model. Biography: I am a master’s student in Health Policy and Management in Seoul National University College of Medicine, Seoul, South Korea. My undergraduate major was in medicine. I am interested in the use of complex systems approach in healthcare, with prior experiences in agent-based modeling. Since I am relatively new to system dynamics, I would like this presentation to be a valuable opportunity for improving and refining my work. Recording: We will record this presentation. Moo-Hyuk will share it by request. If you are interested in presenting your work, please contact Christine Tang (
