Efficiency of organ procurement and transplantation programs

Area of Science:

• Transplantation Science
• Public Health Policy
• Medical Informatics

Background:

• Organ donation and transplantation programs require robust metrics for efficiency evaluation.
• Comparing programs across different years or regions necessitates standardized indices.
• Current data collection methods provide a foundation for developing new evaluation tools.

Purpose of the Study:

• To introduce and define novel indices for assessing organ procurement and transplant system efficiency.
• To demonstrate the utility of these indices in comparing donation and transplant programs.
• To highlight the potential of these indices in evaluating marginal donor and organ utilization.

Main Methods:

• Development of the Caldes I (procurement) and Caldes II (transplant) indices based on existing data.
• Calculation of the harvest index (organ utilization efficiency) and transplant index (transplant team capacity).
• Analysis of index performance in evaluating program efficiency and regional disparities.

Main Results:

• The harvest index shows typical ranges: 80-90% for kidneys, 70-95% for livers, 40-50% for hearts, and 5-15% for lungs.
• The transplant index typically ranges from 60-120%, reflecting transplant team capacity.
• Index determination utilizes standard, readily available data, simplifying implementation.

Conclusions:

• Caldes I and Caldes II indices offer a standardized method for comparing organ donation and transplant program efficiency.
• These indices are critical for evaluating marginal donor/organ utilization and regional disparities in organ retrieval and transplantation.
• The indices facilitate assessment of organ sharing practices between different regions.
