Paediatric organ donation following neurological determinants of death in intensive care units in Saudi Arabia: a retrospective cross-sectional study.

Abstract

The aim of this retrospective cross-sectional study was to assess the performance of paediatric organ donation in intensive care units following neurological determinants of death in Saudi Arabia. Retrospective cross-sectional study. Paediatric intensive care units at three tertiary centres over 5 years. 423 paediatric deaths (<14 years) from January 2017 to December 2021. Patients were identified as either possible, potential, eligible, approached, consented or actual donors based on organ donation definitions from the WHO, Transplantation Society and UK potential donor audit. Secondary outcome was causative mechanisms of brain injury in possible donors. Demographics of the study cohort (age, sex, hospital length of stay (LOS), paediatric intensive care unit LOS, pre-existing comorbidities, admission type and diagnosis category) were compared between possible and non-possible donors. Demographics were also compared between patients who underwent neurological determination of death and patients who did not. Among the 423 paediatric deaths, 125 (29.6%) were identified as possible donors by neurological criteria (devastating brain insult with likelihood of brain death, Glasgow Coma Score of 3 and ≥2 absent brainstem reflexes). Of them, 41 (32.8%) patients were identified as potential donors (neurological determination of death examinations initiated by the treating team), while only two became actual donors. The eligible death conversion rate was 6.9%. The reporting rate to organ procurement organisation was 70.7% with a consent rate of 8.3%. The most common causes of brain insult causing death were cardiac arrest (44 of 125 patients, 35.2%), followed by traumatic brain injury and drowning (31 of 125 patients, 24.8%), and intracranial bleeding (13 of 125 patients, 11.4%). Major contributors to low actual donation rate were consent, donor identification and donor referral.
