Purpose: This study developed and validated a system dynamics model to analyze the supply of and demand for active paramedics. Methods: A system dynamics model was constructed using workforce and emergency medical service data from 2015 to 2024. The model included active emergency medical technicians (EMTs), examination passers, employment rate, attrition rate, and emergency medical service dispatches. Model validity was assessed by comparing simulated and observed values using the mean absolute percentage error (MAPE). Sensitivity analysis was performed to evaluate the effects of key variables on model outcomes. Results: The demand model showed high validity, with a MAPE of 4.60%, whereas the workforce supply model showed a MAPE of 17.8%. Sensitivity analysis showed that changes in attrition rates had a greater effect on the number of active EMTs than changes in workforce inflow. These findings indicate that workforce retention is a critical determinant of paramedic workforce sustainability. Conclusion: The model adequately represented long-term paramedic workforce dynamics. Policies focused on retention, including improved working conditions and career sustainability, may stabilize the workforce more effectively than strategies focused solely on increasing workforce supply.

소개
복합 구조적인 산업사회의 발전에 따라 안전사고와 응급상황에서의 구조구급요청자들이 증가하고 있으나 우리나라의 응급의료체계는 아직 그 수준을 따라가지 못하고 있는 실정이다. 이에 우리나라의 응급의료체계를 확립하고 구조구급에 관한 기초학문의 발전에 기여하고자 학회를 창립한다.
