Kidney procurement system in Colombia: A system dynamics approach*

Abstract

Objective: is paper presents an analysis of two regulatory proposals in response to the growing demand for kidney transplants in Colombia. e results can be useful in evaluating these possible policy interventions once they have been implemented. Methods: e proposed model uses System Dynamics as a tool to understand the behavior of this complex social system if two intervention projects are executed. e rst is a bill of law seeking to expand the legal presumption of organ donation. e second one is to implement a Kidney Exchange Program. e analysis is made in two parts. Firstly, a causal loop diagram is proposed. Secondly, the simulation of the system using a stock and ow diagram is analyzed. Results: Results show that the projects can balance the system and encourage donations. Conclusion: e implementation of a KEP is recommended since it achieves stability of the system earlier than the amendment to the law, with a reduction in the waiting list size.
