44 Identifying Potential Donors in Canada Brain Injury + Ventilated ON: Ventilated and any of the following: Grave prognosis or GCS = 3 OR Injured brain or non-recoverable injury/illness OR Family-initiated discussion of donation or withdrawal of lifesustaining therapy (WLST) OR Therapy-limited, de-escalation of treatment, or WLST discussion planned QC: Severe neuro insult + mechanical ventilation Brain Injury + Ventilated + EOL Care/Discussions Death Declared (NDD) AB (EDM) - ventilated with severe/devastating illness or injury, neuro consult ruling out recovery. Indicators include, but are not limited to: GCS 3 OR 3 or + absent brain stem reflexes OR Plans for WLST OR Family initiated donation discussion BC - GCS < 5, Injury to brain, Ventilated, EOL care SASK - GCS 5 OR Injured brain OR Ventilated (no respiratory effort) OR EOL discussion of WLST MAN - GCS 5 + Severe neuro insult/injury + Ventilator dependent + Grave prognosis/eol discussion NS - GCS < 5, Irreversible Brain Injury, Ventilated, End of life discussion AB (CAL): Patient who is brain dead Actual Donor

45 Deceased Donation Why Data? Currently available Canadian data lack information to estimate potential donors Standardized definitions and clinical triggers are needed to facilitate meaningful comparisons More data needed to inform strategies to address donation-transplant gap

Definition Donor retrieval operation commenced for purpose of transplantation reported to ODO but no transplant realized + actual donors donation criteria met, no transplant realized + actual donors transferred to operating room, at least 1 solid organ retrieved subjects from whom organs were taken (preleve) reported to ODO but no transplant realized + actual donors reported to ODO but no transplant realized + actual donors transferred to operating room, at least 1 solid organ retrieved At least one solid organ retrieved with the intention to transplant At least one organ recovered for the purpose of transplantation
