Abstract 158: Exploring the Potential for Kidney Donation in Out-of-Hospital Cardiac Arrest Cases With No Chance of Survival

Abstract

Introduction: The global kidney shortage can potentially be addressed through the implementation of the uncontrolled donation after circulatory death (uDCD) pathway. However, the current Termination-of-Resuscitation (TOR) rules, although effective in identifying futile resuscitation, do not consider the potential benefits of organ donation. Objective: This study aims to assess the potential pool of uDCD kidney donors among patients with resuscitation attempts by Emergency Medical Services (EMS) who meet TOR criteria. Methods: Retrospective analysis was conducted using data from the Paris Sudden Death Expertise Center (SDEC) registry spanning from 2011 to 2020. TOR criteria evaluation and identification of potential organ donors were performed using established selection criteria from previous protocols on TOR rules and uDCD. Incidence rates (per patient-years) were calculated using data from the National Institute of Statistics and Economic Studies. Results: Out of 19,976 cases of Out-of-Hospital-Cardiac Arrest (OHCA) with resuscitation attempts by EMS, 12,890 (64.5%) did not achieve sustained Return of Spontaneous Circulation (ROSC). Among patients with no successful ROSC, the annual number and incidence of patients with no chance of survival varied across different TOR rules, ranging from 626 to 1081 cases and from 8.14 to 10.04 per 100,000 patient-years. The proportion of OHCA patients meeting both TOR criteria and extended kidney criteria ranged from 67.8% to 73.6% of total cases of OHCA who did not achieve sustained ROSC. Conclusion: Our findings demonstrate that the implementation of a uDCD program, in cases where TOR rules indicate no chance of survival, has the potential to significantly increase the pool of potential organ donors.
