4/25/2017 Organ Donation Trends at Enloe Trauma and DCD Jason Hower Clinical Procurement Coordinator Heal a life through organ and tissue donation Objectives • Explain Donation after Circulatory Death (DCD) • Review Enloe’s recent organ donation history – Trauma impact • Discuss current donation trends • Case review Organ Donation History • Transplants began prior to Brain Death criteria – 1954– 1st successful human kidney transplant – 1963– 1st successful lung transplant – 1967– 1st successful heart transplant • 1968 – Harvard committee defines brain death – 1983 Uniform Determination of Death Act 1 4/25/2017 Organ Donation History • Brain Death and Transplant evolved separately • Prior to Brain Death Law: – donation occurs after “traditional” determination of death • After Brain Death laws, practice differs: – Eastern states vs. Western states Hospital Refers Patient Donor Network Evaluation Brain Death Declaration Family Decides to Withdraw Donation Discussion Donation Discussion Donation occurs AFTER death Brain Death vs. DCD Brain Death • Patient is declared dead as a result of an absence of brain function. • • • Cardiorespiratory function maintained by vent Perfusion, organ function continue Usually no warm ischemic time on organs, but there will be cold ischemic time Circulatory Death • Patient is declared dead as a result of an absence of cardiac function. • All cardiorespiratory function ceases. • Warm ischemia • Warm ischemic time is more harmful to the organs than cold ischemic time. 2 4/25/2017 Brain Death vs. DCD Brain Death • Patient is declared dead as a result of an absence of brain function Cardiorespiratory function maintained by vent • Perfusion, organ function continue • Usually no warm ischemic time on organs, but there will be cold ischemic time • Circulatory Death • Patient is declared dead as a result of an absence of cardiac function • All cardiorespiratory function ceases. • Warm ischemia • Warm ischemic time is more harmful to the organs than cold ischemic time. The Process • Hospital refers potential donor • Potential for DCD determined by Donor Network • Family makes decision to withdraw • Donation offered to family • Timeframe for withdrawal set • Organs allocated, hospital maintains patient • Comfort measures, extubation Evaluation - Predictability • Statistical model (reflexes, oxygenation index) • Age, history, admission course • Diagnostics, severity of injury • Lab values • Neurological status • Vent parameters, respiratory drive • Airway assessment 3 4/25/2017 Comfort Care during Withdrawal of Life Support • As in the ICU, patients receive medication to alleviate any discomfort that may be experienced during the withdrawal of life support. • The doctor that declares the patient dead is responsible for administering comfort care medications. Transplant surgeons are not involved in prescribing comfort care medication or determining when it should be given. Family Presence • The patient’s family may decide to be present during their loved ones last moments. • If the withdrawal of care occurs in the ICU, this is easily accommodated • If the withdrawal of care occurs in the OR, the hospital must OK this practice. • Sometimes the withdrawal can occur in an adjacent procedure room or the PACU to allow the family to be present Timeline • Surgical Team will arrive 1 hour prior to planned OR time (time withdrawal of care will occur) • Surgical Coordinator will assist hospital staff in setting up OR 4 4/25/2017 Huddle • Donation Staff: – Administrator On Call – Transplant & Surgical Coordinators – Family Care & Program Consultant • OR Staff: – Circulator, Scrub • Transplant Surgeons • Declaring Doctor, nurse, clergy ***Make sure everyone is present Huddle • The plan for the DCD will be discussed: • Description of events • Description of roles and responsibilities • Declaring Doctor will discuss plan of withdrawal • The set up of instruments and the room • Who will be in the room during the withdrawal • Hospital has a bed ready for the patient back in the ICU should the case not proceed in the OR • If the patient does not die within ~1 hr, the recovery will not occur and the patient will be brought back to the ICU or other designated area Withdrawal • Limit the number of people in the room during the withdrawal (Privacy for Family): – Declaring physician – ICU nurse (to give comfort care meds) – Donor Network staff to record vitals – Family support (Donor Network, clergy) • The transplant surgeons are often scrubbed in and waiting at this time in a separate room. 5 4/25/2017 Withdrawal • If the family wishes to be present, they will enter the room at this time. • When the patient is determined to have reached cardiac death, the doctor will declare • The 5 minute waiting period begins, the family is escorted out • At the end of the 5 minute period, the transplant surgeons may enter and begin the recovery surgery. Withdrawal • If the patient does not reach asystole within the pre-determined time frame of 60 minutes or less, they will not become an organ donor but may still become a tissue donor after asystole. • The patient is taken back to the ICU or other room in the hospital where they will continue to receive comfort care medications until they reach asystole. • They are not reintubated. Important Points 1) Withdrawal and comfort care are directed by the declaring doctor from the hospital. – Donor Network and transplant centers DO NOT have any input as to what comfort care medications are given. 2) Limit the number of people in the room during the withdrawal. – Only 1 person from DNW should be present in the room during withdrawal in order to record vitals and provide updates to the transplant surgeons – If the family is present, having an FRC in the room is also appropriate 6 4/25/2017 Withdrawal Patient Reaches Cardiac Death Patient Does Not Reach Cardiac Death Organ Recovery Commences Patient brought back to ICU Ethics of DCD • Surgical recovery of organs occurs only after declaration of death and with explicit authorization of the donor and/or donor's family. • Death is declared by doctors not affiliated with organ recovery or transplantation. • The transplant surgeons are not present during the time of withdrawal of life support. • After cardiac death is declared, a 5 minute observational/waiting period begins Ethics of DCD continued • Patients and their families, in collaboration with their health care providers, decide if and when to withdraw artificial support. • Decisions to withdraw artificial support are made independent of whether or not the person becomes a donor. • Donor Network West is never involved in decisions to withdraw treatment. 7 4/25/2017 Ethics of DCD continued • Practice differs between facilities • DCD donation is family driven • All families informed of potential to donate DCD at Enloe • 2012 – 2 donors, 0 DCD (0 trauma) • 2013 – 8 donors, 0 DCD (7 trauma) • 2014 – 4 donors, 0 DCD (2 trauma) • 2014 – Revised DCD procedure, checklist • 2015 – 9 donors, 2 DCD (1 trauma) • 2016 – 11 donors, 2 DCD (4 trauma, 1 DCD*) Case #1 • 39yo male s/p drowning • 4 days in NTICU, donation brought up by family • Initial BD exams not consistent w/BD, DCD authorized • BD exams repeated on day 5 • Heart, liver, kidneys transplanted, lungs r/o in OR 8 4/25/2017 Case #2 • 35yo male s/p fall from horse • Bilateral craniectomy on day 2 • PM shift, day 2: – CT shows complete infarct rt. Hemisphere – Family brings up donation, wants to wait for BD – DCD authorized as plan B • DCD donation on day 5 • Lungs (!!), liver, kidneys transplanted, heart for research Challenges? Intermountain Donor Services Nevada Donor Services 9 4/25/2017 Challenges? • WARM ISCHEMIA/COLD ISCHEMIA • Predictability • Instability DCD potential from trauma • Severity of injury, not quite BD • Instability • Family fatigue, timing for comfort care • Interventions prevent herniation Donation from trauma • % Donors/trauma pt.s = declining* – Increasing age/comorbidity • Lower trauma mortality • Organs per donor 1.6x higher (BD vs. DCD) – 2x higher for hearts DONATION OPPORTUNITIES ARE PRECIOUS 10 4/25/2017 Preserve donation opportunities • Early identification – Clinical Cues • Early notification • Aggressive intervention (avoid deceleration of care) • PLAN AHEAD FOR DONATION DISCUSSIONS! 11
