Health System PerspectivesServing the Needs of Canadians

1. End stage organ failure and bridges to transplant are difficult burdens, life threatening to patients and expensive to the system

2. Transplantation is life saving, life preserving and cost effective but limited by insufficient transplantable organs

3. Donation/transplantation is widely supported by the Canadian public

4. Countries/regions have a responsibility to address their domestic supply of transplantable organs in ethically legitimate ways

Called for a Moratorium on DCD

Canadian Critical Care Society Statement Jan 2007

•Endorsement of the DCD recommendations was passed.

•These recommendations represent the mostcomprehensive deliberation on DCD in any jurisdiction.

•Not recommending or advocating DCD:Obtaining consensus on DCD throughout the entire CCM community is not a realistic objective

•Individual health centres or regions should be free to adopt the recommendations as a guide the development of DCD programs.

DCD in Canada

For Hospitals or Health Regions, the question was:

• Whether to do it1. Concerns about ICU EOL decision-making and practice 2. Donation option and interventions may arise before

death is established3. Diagnosis of death and immediacy of procurement4. Resource implications

DCD in CanadaFor Hospitals or Health Regions, the question is

• Why Not do it1. Withdrawal of life sustaining technology is standard

practice prior to death2. Response to donor individual/family requests &

expectations3. Advance of DCD programs outside of Canada4. Societal needs re transplantation 5. Public support

Sarah Beth Therien1st Modern Day DCD in Canada

NOVEMBER 1, 1973 - JUNE 17, 2006

• In a twist of fate, just a week before she became gravely ill, Sarah Beth watched a documentary on organ donation. The program moved her to tell us: "Just so you know, I've signed a card." Organ donation can be difficult to discuss for a young, vibrant and healthy person. But she made it very clear: "If I'm gone, I want someone else to live." Who could have known how important this conversation was to be.

• The family very much wanted to honour Sarah Beth's wishes to become an organ donor after the brief, sudden illness that placed her on life support. We approached an ICU nurse at the Ottawa Hospital and were told that brain death was the only criterion for organ donation.

• Before making the independent decision to withdraw life support, we approached the health-care team about Sarah Beth's wishes to become an organ donor. The compassionate health-care team at the Ottawa Hospital and Trillium Gift of Life Network were determined to do their best to fulfill Sarah Beth's wish: She was always one to make things happen and they wanted to do the same for her. In this situation, donation after cardiac death (DCD) was the only option to make Sarah Beth's wish possible.

• The work done to meet Sarah Beth's wish helped change the protocol and make DCD acceptable. DCD marks a new era for organ donation in Canada with the potential to increase donations by 25 per cent across the country. Shortly after her death, two people received her organs. They are now on their way to full recovery.

Uncontrolled DCD in Canada?

Personal opinion: Is not feasible nor justified because:

• Consent during refractory cardiac arrest• Interventions that reinstitute oxygenated circulation

to the brain invalidate determination of death• Efforts to save patient’s organs before saving

patient’s life

The system should invest in extracorporeal resuscitation &coronary revascularization for refractory cardiac arrest

Save life 1st, save organs 2nd

DCD in Canada: Summary

1. Controlled DCD has advanced in Canada

• quantitatively, the most important contributor to increasing organ donation performance

• actual kidney, lung, liver and heart (pending)

• implemented in 6/10 provinces, lead by Ontario

• 499 DCD donors and 1136 DCD transplants to date

2. Anoxic brain injury is the most common cause of DCD donation

3. International experience with uncontrolled DCD is favorable, but unlikely to work in the Canadian context

4. Research and clinical investment in advanced CPR-ECMO and coronary revascularization may benefit patients first, and organ donation secondarily

Aim: Extracorporeal resuscitation during cardiopulmonary resuscitation (ECPR) deploys rapid cardiopulmonary bypass to sustain oxygenated circulation until the return of spontaneous circulation (ROSC).The purpose of this systematic review is to address the defining elements and outcomes (quality survival and organ donation) of currently active protocols for ECPR in refractory out-of-hospital cardiac arrest (OHCA) of cardiac origin in adult patients. The results may inform policy and practices for ECPR and help clarify the corrresponding intersection with deceased organ donation.Methods: We searched Medline, Embase, Cochrane and seven other electronic databases from 2005 to 2015, with no language restrictions. Internal validity and the quality of the studies reporting outcomes and guidelines were assessed. The review was included in the international prospective register of systematic reviews (Prospero, CRD42014015259).Results: One guideline and 20 outcome studies were analysed. Half of the studies were prospective observational studies assessed to be of fair to good methodological quality. The remainder were retrospective cohorts, case series, and case studies. Ages ranged from 16 to 75 years and initial shockable cardiac rhythms, witnessed events, and a reversible primary cause of cardiac arrest were considered favourable prognostic factors. CPR duration and time to hospital cannulation varied considerably. Coronary revascularization, hemodynamic interventions and targeted temperature management neuroprotection were variable. A total of 833 patients receiving this ECPR approach had an overall survival to hospital discharge rate of 39%, including 12% with good neurological recovery. Additionally, 88 potential and 17 actual deceased organ donors were identified among the non-survivor population in 8 out of 20 included studies. Study heterogeneity precluded a meta-analysispreventing any meaningful comparison between protocols, interventions and outcomes. Conclusions: ECPR is feasible for refractory OHCA of cardiac origin in adult patients. It may enable neurologically good survival in selected patients, who practically have no other alternative in order to save their lives with quality of life, and contribute to organ donation in those who die. Prospective studies are required to clarify patient selection, modifiable outcome variables, risk-benefit and cost-effectiveness.

Logistics of DCD

Prior to Death:1. Patients and etiologies2. Decisions for WLST 3. Predictions of death after WLST4. Consent discussions5. Procedures to WLST

1. Palliative and comfort care2. Mechanics and Responsibility3. Location

6. Death determinations7. Separation of duties between ICU, OPO, TP team

Patient Conditions in Controlled DCD

1. Dependence on life sustaining therapy= airway, ventilatory and/or hemodynamic support

2. Consensual decision to withdraw LST

3. Anticipation of death

4. May include:i. Severe brain injury- irretrievably poor outcome

i. Anoxia, trauma, CVA/ICHii. End stage neuromuscular diseasesiii. High spinal cord injuriesiv. End stage single organ failure

1. The medical and ethical framework for WLST in the ICU falls within the domain of critical care practice and should not be influenced by donation potential.

2. The management of the dying process, including procedures for WLST, sedation/analgesia/ comfort care should proceed according to existing ICU practice in the best interests of the dying patient.

3. It is the responsibility of the critical care and neurocritical care communities to ensure optimal and safe practice in this field.

Time to loss of brain function and activity during circulatory arrestR.M.Pana, L. Hornby, S.D. Shemie, S. Dhanani, J. Teitelbaum

Objective: Brain function during the dying process and around the time of cardiac arrest

is poorly understood. In order to better inform clinical physiology and organ donation

practices, we performed a scoping review of the literature to assess time to loss of

brain function and activity after circulatory arrest.

Data Sources: Medline and Embase databases were searched from inception to

June 2014 for articles reporting the time interval to loss of brain function or activity after

loss of systemic circulation.

Study Selection: Original articles reporting time intervals to loss of brain function and/or

brain activity during circulatory arrest were included.

Data Extraction: 39 studies met selection criteria. In humans, the data was extracted

mostly from case reports and case series. Animal data was extracted from animal

models of systemic circulatory arrest or global cerebral hypoperfusion.

Data Synthesis: Seven human studies and 10 animal studies reported that EEG

activity is lost less than 30 seconds after abrupt circulatory arrest. In the setting of

existing brain injury, with progressive loss of oxygenated circulation, loss of EEG

may occur prior to circulatory arrest. Cortical evoked potentials may persist for

several minutes after loss of circulation.

Conclusion: The time required to lose brain function varied according to clinical

context and method by which this function is measured. Most studies show that clinical loss of

consciousness and loss of EEG activity occur within 30 seconds after abrupt circulatory arrest,

and may occur prior to circulatory arrest after progressive hypoxia-ischemia.

Prospective clinical studies are required to confirm these observations.

After a cardiac arrest, how long does it take before you are dead?

1. NDD (brain death) only?

= deceased donor rates will not improve.

2. NDD & DCD = all patients with catastrophic brain injurywho have withdrawal of mechanical ventilation?

= deceased donor rates (NDD & DCD) will likely improve
