A MULTIMETHODOLOGICAL APPROACH TO ORGAN DONATION LOGISTICS: SYSTEMIC ANALYSIS OF BRAZILIAN FEDERAL UNITS THROUGH QUALITATIVE SYSTEM DYNAMICS AND EFFICIENCY ASSESSMENT USING DATA ENVELOPMENT ANALYSIS

ABSTRACT

Organ transplantation plays a significant role in the healthcare sector, offering hope to patients with chronic diseases and organ failure. However, the logistical aspects of organ transplants present significant hurdles, with inefficiencies leading to organ loss during transportation and fatalities while on the waiting list. In this study, the combined use of Qualitative System Dynamics and Data Envelopment Analysis is employed to investigate, map, and analyze the efficiency of organ transplant logistics across different Brazilian Federative Units. From the Causal Loop Diagram, five (three as inputs and two as outputs) variables were selected to assess the efficiency through an output-oriented Data Envelopment Analysis model considering constant returns to scale. The results highlight efficient/inefficient Units, offering benchmarks and targets for improvement. This integration of methodologies provides a comprehensive perspective, empowering informed and strategic decision-making in the development of effective public policies and optimal allocation of public resources, thereby enhancing precision and efficiency.
