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

OBJECTIVES

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.

DESIGN

Retrospective cross-sectional study.

SETTING

Paediatric intensive care units at three tertiary centres over 5 years.

PARTICIPANTS

423 paediatric deaths (<14 years) from January 2017 to December 2021.

PRIMARY OUTCOME: 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: 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.

RESULTS

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%).

CONCLUSION

Major contributors to low actual donation rate were consent, donor identification and donor referral.
