National Deceased Donor Potential Study: Updates and Next Steps Karl J. McCleary, Ph.D., M.P.H., Scientific Director, CTSE Principal Investigator, DDPS Affiliate Faculty, School of Medicine, Virginia Commonwealth University Acknowledgement: The Deceased Donor Potential Study is a commissioned study funded by the Organ Procurement and Transplantation Network (OPTN) under Task 6 of the existing contract. The OPTN is supported by Health Resources and Services Administration (HRSA), Healthcare Systems Bureau, Division of Transplantation’s contract #234-2005-370011C. The content described here is the responsibility of the author alone and does not necessarily reflect the views or policies of the Department of Health and Human Services, the OPTN, or UNOS; nor does mention of trade names, commercial products, or organizations imply endorsement by the US Government.
The “Question” • What is the “true” potential for deceased organ donation in the United States?
Purpose of Study • The DDPS aims to generate more current scientific evidence that is based on rigorous epidemiologic, population, demographic, and geographic analyses of the deceased donor system for the purposes of determining the potential number of organ donors, and to determine the potential trend in that number over time.
Research Strategy • Build a unifying framework for understanding deceased donor potential, linking existing bodies of knowledge and specific research traditions that are relevant to transplantation withthe power of transdisciplinary science approach. • Examine deceased donor potential from a complex system view.
Important Qualifiers or Clarifying Points about the Study • What the study is not: • Does not include OPTN policy formation and analysis. • Does not include any focus on organ allocation or distribution. • Does not include any recommendations on differing geographic units of measure or operational approaches. • Study is not focused on current understandings or classifications typically used for compliance reasons (ECD, SCD, etc.).

Data source triangulation for Donor Potential Number • The CIG, OPO, and Data Subcommittees will collaborate to provide three different estimates of donor potential using different databases and similar filters • This range of estimates will also be used in the System Dynamics Deceased Donor Potential model

Donor Potential Estimates #2 & #3 Custom Criteria for Filter 4. OPTN Donors 3. OPTN Database 2. All Medically Suitable Deaths 1. All Deaths
Proposed Procedure for Developing and Applying Custom Criteria for Medical Suitability for Deceased Donation Goal: Apply Custom Filters to Datasets Synthesize and Operationalize Criteria Within the Constraints of Available Data (Data Subcommittee) Criteria from OPO Leaders and Procurement Professionals (OPO Subcommittee) Criteria from Clinicians and Caregivers (CIG Subcommittee)
Donor Potential Gap Analysis: Actual v. Potential • Build comprehensive dataset (includes NCHS and California’s Death Statistical Master files match-merged with OPTN Deceased Donor data + Census data) • Conduct comparative donor gap analyses • Use logistic regression models to determine probability of • Donation if eligible • OPTN Database - if medically suitable • OPTN Donor- if medically suitable 4.
