Ethics, Communication & Professionalism

Organ donation: discussion and process

Clinical Overview and When to Suspect Donation Eligibility

— Donation after brain death (DBD): irreversible cessation of all brain function including brainstem; legally dead under the Uniform Determination of Death Act (UDDA).

— Donation after circulatory death (DCD): planned withdrawal of life-sustaining therapy in a patient with non-survivable injury who does not meet brain death criteria; death declared after a mandated 2–5 minute "no-touch" period of asystole.

— Catastrophic neurologic injury (anoxic brain injury post-arrest, massive ICH, severe TBI, brainstem stroke)

— GCS ≤ 5, loss of ≥ 3 brainstem reflexes, or family discussion of withdrawal of care

— Imminent death from non-survivable illness

Step 3 management: When a patient with devastating neurologic injury is being considered for withdrawal of care or meets brain death criteria, your first system-level action is notify the OPO — before any family conversation about donation, and regardless of presumed family wishes.

Organ donation is a structured medico-legal process governed in the US by the Uniform Anatomical Gift Act (UAGA), CMS Conditions of Participation, and oversight from the Organ Procurement and Transplantation Network (OPTN/UNOS).

Two donation pathways:

When to suspect a potential donor:

Mandatory referral rule: Federal law (CMS) requires hospitals to notify the local Organ Procurement Organization (OPO) of every imminent death or death within a defined time window — not to obtain consent themselves. Failure to refer is a Conditions of Participation violation.

Treating team must not initiate the donation conversation; this is delegated to OPO-trained requestors to avoid coercion and conflict of interest ("decoupling" or "required request" principle).

Donation discussions are a Step 3 favorite because they fuse end-of-life communication, legal definitions of death, and systems-based practice.

Presentation Patterns and Key History

— Young patient with anoxic brain injury after out-of-hospital cardiac arrest, day 3, no brainstem reflexes

— Traumatic brain injury with herniation and fixed dilated pupils on the ventilator

— Massive intracerebral hemorrhage with loss of brainstem function

— Family meeting planned to withdraw life-sustaining therapy in a non-recoverable patient

— Documented donor designation: driver's license, state donor registry, advance directive, living will. A first-person authorization is legally binding under UAGA — family cannot override it.

— Surrogate hierarchy if no first-person authorization: spouse → adult children → parents → adult siblings → legal guardian (varies by state).

— Cause and mechanism of injury (affects organ suitability)

— Time of injury, downtime, hypotensive episodes

— Infections (HIV, HCV, HBV, active sepsis, untreated TB, prior cancers — though many are not absolute exclusions today)

— Social history relevant to increased-risk donor (PHS criteria) designation: IV drug use, incarceration, high-risk sexual behavior in past 12 months

Board pearl: First-person authorization (donor card/registry) is legally sufficient under UAGA in all 50 states; the family's role becomes confirmatory and supportive, not consenting.

Typical Step 3 vignette setups that should trigger donation-process thinking:

Key history elements to gather:

Key distinction: A patient who is a registered donor has already given consent. The family is informed and supported, not asked for permission. This is frequently tested — choosing "respect the registry designation" beats "defer to grieving family."

Pre-existing conditions that used to be exclusions but now often are not: hepatitis C (with DAAs), HIV (HOPE Act donor-to-recipient), advanced age, mild CKD.

Cardiac arrest itself does not disqualify donation — DCD and even DBD pathways remain open after ROSC with subsequent neurologic devastation.

Physical Exam Findings and Brain Death Assessment

— Known, irreversible catastrophic brain injury with proximate cause identified on imaging

— Core temperature ≥ 36°C

— SBP ≥ 100 mmHg (vasopressors allowed)

— No confounding sedatives, paralytics, or severe metabolic/endocrine derangement

— No severe acid-base, electrolyte, or endocrine abnormality

— Train-of-four to confirm absence of neuromuscular blockade

— Coma with no response to noxious central stimuli

— Absent pupillary light reflex (fixed, mid-position 4–9 mm)

— Absent corneal reflex

— Absent oculocephalic ("doll's eyes") and oculovestibular (cold caloric) reflexes

— Absent gag and cough with deep tracheal suction

— No motor response to noxious stimulation in all four extremities (spinal reflexes permitted)

— Preoxygenate to PaO₂ > 200, disconnect ventilator with O₂ insufflation

— Observe 8–10 minutes for respiratory effort

— Positive (confirms apnea) if PaCO₂ rises ≥ 60 mmHg or 20 mmHg above baseline with no respiratory drive

— Abort if SBP < 90, SpO₂ < 85%, or significant arrhythmia

CCS pearl: Order "brain death exam," "apnea test," ABG before/after apnea, and "notify OPO" as discrete CCS actions. Do not order ancillary tests (EEG, nuclear flow scan, TCD) unless the clinical exam or apnea test cannot be completed.

Brain death examination prerequisites (must satisfy all before testing):

Clinical brain death exam — must demonstrate all:

Apnea test (the definitive component):

Number of exams: AAN 2023 update — one complete exam by a qualified clinician suffices in adults; many institutions still require two. Pediatrics requires two exams with an interval (24h neonates, 12h older children).

Diagnostic Workup — Initial Labs and Donor Suitability Screening

— CBC, CMP, magnesium, phosphate, calcium

— PT/INR, PTT, fibrinogen

— ABG every 2–4 hours during donor optimization

— Lactate, troponin, BNP for cardiac suitability

— LFTs, lipase, amylase for hepatic/pancreatic grafts

— Urinalysis with microscopy, urine protein/creatinine ratio

— Blood and urine cultures, sputum Gram stain/culture

— HIV 1/2 Ab + NAT

— HCV Ab + NAT

— HBV: HBsAg, anti-HBc, HBV NAT

— HTLV I/II, CMV, EBV, syphilis (RPR), toxoplasma

— West Nile NAT seasonally, SARS-CoV-2 PCR per current policy

— Chagas, strongyloides in epidemiologically appropriate donors

— CXR for lung evaluation

— Bedside echo for cardiac function (EF, wall motion, valves)

— CT chest/abdomen/pelvis often for anatomy and occult pathology

— Bronchoscopy for lung donors

Board pearl: A history of IV drug use within the past 12 months triggers PHS Increased Risk Donor labeling (terminology has shifted to simply disclosing risk), but with mandatory NAT, transmission risk is < 1 per 10,000. Recipients are informed but transplantation routinely proceeds — this is not a contraindication.

Once OPO is notified and donation is being pursued, donor management labs are obtained — typically by the OPO coordinator with the bedside team's collaboration:

Mandatory serologic screening (per OPTN policy):

ABO blood typing confirmed by two separate draws — required to prevent fatal mismatch.

HLA typing is performed by OPO's histocompatibility lab from peripheral blood.

Imaging:

Diagnostic Workup — Ancillary Studies for Death Determination

— Severe facial trauma precluding cranial nerve testing

— Pre-existing pupillary abnormalities

— Toxic levels of sedatives that cannot be cleared (e.g., chronic phenobarbital)

— High cervical cord injury or severe pulmonary disease preventing safe apnea testing

— Sleep apnea or chronic CO₂ retention with unreliable PaCO₂ thresholds

— Cerebral angiography — gold standard; demonstrates absence of intracranial filling at the level of the carotid bifurcation and circle of Willis

— Radionuclide cerebral perfusion scan (HMPAO SPECT) — "hollow skull sign," no parenchymal uptake

— Transcranial Doppler — small systolic peaks or reverberating flow indicating no net forward flow

— EEG — electrocerebral silence over 30 minutes (less favored; vulnerable to ICU artifact and sedatives)

Key distinction: In DBD, the patient is legally dead before organ recovery; the ventilator continues to support organs, not the patient. In DCD, the patient is alive at the time life support is withdrawn, dies from circulatory arrest, and is then declared dead — only after the mandated no-touch period may recovery begin. The dead donor rule is preserved in both pathways and is the ethical bedrock of US transplantation.

Ancillary brain death testing is used only when the clinical exam or apnea test cannot be completed or is unreliable:

Accepted ancillary tests (any one is sufficient when properly performed):

Ancillary tests are confirmatory, not substitutes for an adequate clinical exam when one is possible.

For DCD candidates, no brain death determination is needed — death is declared by circulatory criteria after withdrawal of life support, requiring an observed period of pulselessness (typically 5 minutes, minimum 2) before organ recovery proceeds.

Decoupling, Authorization, and the Conversation Framework

— The ICU team discusses prognosis, withdrawal, and comfort care.

— The OPO coordinator (with or without a trained hospital "designated requestor") discusses donation.

— Mixing these roles is associated with lower authorization rates and creates a perceived conflict of interest.

1. Check the donor registry / driver's license first — first-person authorization is binding.

2. If registered: OPO informs the family of the prior decision and supports them through the process.

3. If not registered: surrogate is approached per state hierarchy.

4. Document authorization (written or recorded verbal per state law).

— Private, quiet setting; sufficient time

— Confirm family understands the patient is dead (in DBD) or that death is imminent (in DCD) before donation discussion

— Use the word "dead," not "brain dead" alone — families often misinterpret "brain dead" as still alive

— Avoid the phrase "life support"; use "organ support" or "ventilator support" after death is declared

— Address culturally and religiously informed concerns

Step 3 management: If a family asks the primary team "Should we donate?", redirect: "That's an important decision and I want to make sure you have specialized support — I'll have the donation coordinator come speak with you." Do not advocate for or against donation as the treating physician.

The decoupling principle: the conversation about prognosis and end-of-life decisions must be separated in time and personnel from the conversation about organ donation.

Sequence of authorization:

Communication best practices (Step 3 vignettes love these):

Costs of donation are never billed to the family — all donation-related costs transfer to the OPO at the time of declaration.

Donor Management — Pharmacologic and Physiologic Optimization

— SBP > 100 mmHg, MAP 60–100

— HR 60–120

— UOP > 1 mL/kg/hr (but not >> 4, suggesting DI)

— PaO₂ > 100, SpO₂ > 95%

— Hgb > 7 (transfuse to support delivery)

— Neurogenic hypotension from loss of sympathetic tone → balanced crystalloid + norepinephrine or vasopressin (vasopressin preferred, also treats DI)

— Central diabetes insipidus (polyuria > 4 mL/kg/hr, dilute urine, hypernatremia) → desmopressin (DDAVP) ± vasopressin infusion

— Hypothermia from hypothalamic failure → warming blankets, warmed fluids; maintain ≥ 36°C

— Adrenal/thyroid axis collapse → "hormone resuscitation": methylprednisolone 15 mg/kg, levothyroxine (T4) infusion, vasopressin, and insulin to keep glucose 140–180

— Coagulopathy from tissue thromboplastin release → correct with FFP/platelets as needed

CCS pearl: In a brain-dead donor with polyuria and rising Na (e.g., 156), order DDAVP, switch maintenance fluids to D5W or hypotonic saline, and recheck sodium q2–4h. Hypernatremia > 155 historically disqualifies liver grafts.

After declaration of brain death, the goal pivots from brain protection to organ optimization. The OPO usually assumes management, but the ICU team executes orders.

Hemodynamic goals (the "rule of 100s" is a useful mnemonic):

Common derangements after brain death and their management:

Lung-protective ventilation: TV 6–8 mL/kg IBW, PEEP 8–10, recruitment maneuvers; goal PaO₂/FiO₂ > 300 to qualify lungs for transplant.

Avoid excessive fluid resuscitation — lung edema disqualifies lung donation. Balance with cardiac and renal preload needs.

The Procurement Process and Allocation Logistics

— ABO compatibility

— HLA matching (especially kidney, pancreas)

— Recipient medical urgency (MELD for liver, LAS for lung, Status 1A/1B for heart)

— Body size, distance from donor hospital, time on waitlist

— CPRA (panel-reactive antibody) for sensitized kidney candidates

— Multi-organ recovery performed in a sterile OR by visiting transplant surgical teams

— Order typically: heart → lungs → liver → pancreas → intestine → kidneys

— Cold preservation solutions (UW, HTK, Celsior) flushed in situ

— Cold ischemic time targets: heart < 4–6 h, lung < 6–8 h, liver < 12 h, pancreas < 12 h, kidney < 24 h (machine perfusion extends this)

— Withdrawal of life support occurs in the OR or a designated location

— If death does not occur within a defined window (typically 60–90 minutes), donation is aborted and patient returned to comfort care

— After asystole and the 5-minute no-touch period, death is declared by a physician not part of the recovery team, and procurement proceeds

Key distinction: The physician declaring death must be separate from the procurement and transplant teams to preserve the integrity of the dead donor rule and avoid any conflict of interest.

Once authorization is obtained and the donor is stable, the OPO enters the donor into UNet (UNOS allocation system), which generates a ranked match list per organ based on:

Allocation has shifted from geographic donor service areas to concentric circles / continuous distribution models to improve equity (kidney 2021, lung 2023, heart pending).

Operative procurement:

DCD procurement specifics:

Normothermic regional perfusion (NRP) and ex-vivo organ perfusion are expanding the DCD donor pool, especially for hearts and livers.

Special Populations — Elderly and Renal/Hepatic Donors

— "Expanded criteria donor (ECD)" kidney historically: age > 60, or age 50–59 with two of (HTN, Cr > 1.5, CVA cause of death). Replaced in 2014 by the Kidney Donor Profile Index (KDPI), a continuous 0–100% score predicting graft longevity.

— KDPI > 85% kidneys go to consented recipients who accept shorter expected graft life in exchange for shorter waitlist time.

— Creatinine trends, UA, urine protein/Cr ratio

— Imaging for cysts, masses, vascular anatomy

— AKI from hypotension or rhabdomyolysis is often reversible and not an automatic exclusion — kidneys with AKI can recover after transplant

— LFT trends (mild transaminitis from trauma/shock acceptable)

— Imaging for steatosis; biopsy if > 30% macrosteatosis suspected

— Hepatitis B core antibody-positive livers acceptable for select recipients with prophylaxis

— Hepatitis C NAT-positive organs now transplanted into HCV-negative recipients with direct-acting antiviral post-transplant therapy

— Independent donor advocate (no role in recipient care)

— Psychosocial evaluation

— Confirmation of voluntariness and absence of financial coercion

— National Living Donor Assistance Center available for travel/lost-wage support

Board pearl: A 68-year-old brain-dead donor with HTN and Cr 1.4 is still a viable kidney donor — KDPI quantifies risk; the kidneys are offered to appropriately consented candidates rather than discarded.

Age alone is not an absolute contraindication to donation. Donors in their 70s and even 80s are routinely accepted for kidney and liver donation.

Renal function evaluation in donors:

Hepatic evaluation:

Living donation (kidney, partial liver, rarely lung lobe) requires:

Special Populations — Pediatric, Pregnant, and Minor Donors

— Term newborn to 30 days: two exams 24 hours apart, both with apnea testing

— 30 days to 18 years: two exams 12 hours apart

— Each exam by a different qualified examiner

— Ancillary testing more liberally used in neonates and infants due to immature exam reliability

— Parental authorization required (both parents if both have legal custody and are reachable)

— Children may have donor designations in some states beginning at age 15–17 (state-dependent)

— Pediatric organs are size-matched and prioritized to pediatric recipients

— Anencephalic infants: cannot donate under the dead donor rule because they retain brainstem function and do not meet whole-brain death criteria — a long-standing ethical/legal limit

— If brain death occurs in a pregnant patient, the viability of the fetus must be considered before withdrawal or organ recovery

— Somatic support of a brain-dead pregnant patient until fetal viability has precedent and may be ethically and legally indicated, especially after 20–24 weeks

— State laws on pregnancy exclusions in advance directives vary widely — Step 3 may test the conflict between advance directive and fetal interests

— Generally prohibited except in extraordinary circumstances (e.g., identical-twin sibling bone marrow or, rarely, kidney) and only with court approval, independent advocacy, and clear benefit to the minor donor

Key distinction: Anencephaly and persistent vegetative state are not brain death. Patients in PVS retain brainstem function (sleep-wake cycles, breathing) and are alive — they cannot be organ donors via DBD; donation requires either recovery determination as non-survivable with family-elected DCD pathway after withdrawal, where appropriate.

Pediatric brain death determination differs from adult:

Pediatric donation:

Pregnant donors:

Minors and living donation:

Complications and Adverse Outcomes in the Donation Process

— Cardiac arrest before recovery (most common reason for lost donors)

— Refractory hypoxemia disqualifying lungs

— Hypernatremia > 155 historically disqualifying liver

— Uncontrolled infection developing during ICU stay

— Revocation of authorization (uncommon but legally permitted up to procurement)

— Family conflict between members with different surrogate priority

— Cultural or religious objections discovered late

— Distress from misunderstanding brain death — "how can my child be dead if their heart is beating?" is a critical communication point

— Bacterial (most common): bacteremia, multidrug-resistant organisms

— Viral: HIV, HCV, HBV (now minimized by NAT screening), CMV, rabies, West Nile, LCMV

— Malignancy: especially undetected CNS tumors, melanoma, renal cell carcinoma

— All recognized transmissions must be reported to OPTN under the Disease Transmission Advisory Committee (DTAC)

— Patient does not arrest within recovery window (~20% of cases) → donation aborted, comfort care resumed

— Warm ischemic time prolonged → graft dysfunction, primary nonfunction

— Ethical concerns about ante-mortem interventions (heparin, vessel cannulation) — practices vary by institution and state

Step 3 management: Suspected donor-derived infection in a recent transplant recipient → notify the OPO and transplant center immediately; the OPO will trace and alert all other recipients of the same donor. This is a mandatory, time-critical patient safety action.

Loss of organs during donor management:

Family-related complications:

Disease transmission to recipient (very rare but devastating):

DCD-specific issues:

Institutional risks: failure to refer to OPO = CMS Conditions of Participation violation, jeopardizing Medicare funding.

When to Escalate — OPO Notification, Ethics, and Consultation

— Imminent death: ventilator-dependent patient with severe neurologic injury and either documented absence of ≥ 3 brainstem reflexes, family discussion of withdrawal, or planned brain death testing

— Any death within the hospital meeting OPO-specific clinical triggers (typically GCS ≤ 5 on a vent)

— Timing: as soon as criteria are met, before withdrawal, before brain death testing, and before any family donation discussion

— Family disputes brain death diagnosis or requests indefinite somatic support ("reasonable accommodation" laws in NJ, NY, CA require some religious accommodation)

— Conflict between advance directive (wished to donate) and family objection

— Question of decisional capacity in a surrogate

— DCD candidate where withdrawal of life support is being considered for non-donation reasons but donation arises

— Cases involving the medical examiner / coroner (homicide, suspicious death, pediatric death) — ME has jurisdiction but rarely refuses donation; coordination is required

— Suspected abuse or neglect as cause of death (mandatory reporting to authorities runs parallel to donation)

— Incarcerated patients

CCS pearl: Orders to place on a potential donor before formal OPO transfer: continue ventilator support, maintain MAP > 60, q2h neuro checks, hold sedation if possible for exam, notify OPO, social work and chaplaincy consult. Do not order palliative extubation until OPO has spoken with family.

Trigger criteria for OPO notification (mandatory under CMS):

Ethics consultation is appropriate when:

Legal consultation / risk management:

Palliative care co-management of family throughout DCD pathway is best practice — they manage grief and symptom control during withdrawal; OPO manages logistics.

Differentials — Conditions Mistaken for Brain Death

— Severe hypothermia (< 32°C) — neurologic exam unreliable; rewarm first

— Drug intoxication: barbiturates, benzodiazepines, opioids, baclofen, TCAs — wait for 5 half-lives or use specific reversal; check levels if available

— Neuromuscular blockade residual — confirm with train-of-four

— Severe metabolic derangement: hepatic encephalopathy, uremic coma, profound hyponatremia, hypoglycemia, myxedema

— Locked-in syndrome (ventral pontine stroke) — patient is awake, retains vertical gaze and blinking; EEG is normal

— Guillain-Barré syndrome, severe — total areflexic paralysis can mimic brain death; pupils and EEG distinguish

— Post-cardiac-arrest syndrome within 24–72 hours — wait minimum 24 h (often 72 h) after ROSC, longer if targeted temperature management used, before brain death evaluation

— Eyes open, sleep-wake cycles, brainstem reflexes intact

— NOT brain dead, NOT an organ donor candidate via DBD

Key distinction: Brain death requires loss of all brain function including brainstem and the capacity to breathe (apnea test). Any preserved brainstem reflex or respiratory drive immediately invalidates the diagnosis — no matter how poor the prognosis or how flat the EEG.

Conditions that mimic brain death and must be excluded before declaration:

Persistent vegetative state (PVS):

Minimally conscious state: inconsistent but reproducible awareness; cannot donate via DBD.

Coma of any cause that retains brainstem reflexes is not brain death.

Differentials — Donation Pathways and Alternatives

— DBD (donation after brain death): patient meets neurologic criteria; ventilator continues post-declaration; multi-organ recovery typical (heart, lungs, liver, pancreas, kidneys, intestine).

— DCD (donation after circulatory death): non-survivable injury but doesn't meet brain death; family elects withdrawal; donation after asystole; typically kidneys/liver, increasingly heart with NRP.

— Living donation: kidney, liver lobe; healthy donor undergoes elective surgery.

— Tissue donation: cornea, skin, bone, heart valves, vessels — recoverable up to 24 hours after cardiac death from a much broader donor pool; far fewer exclusions; does not require brain death.

— Whole-body donation (anatomical gift to medical school): governed by UAGA but separate from organ donation; typically incompatible with organ donation in the same patient.

— Comfort care / hospice with no donation

— Continued aggressive care if family/patient declines withdrawal even with poor prognosis

Board pearl: A patient declared dead by cardiopulmonary criteria outside the operating room context can still donate tissues (corneas, bone, skin) within hours — even when organ donation is no longer feasible. Don't forget to ask the OPO about tissue donation in every hospital death.

Differentiating the donation pathways and end-of-life options:

Non-donation end-of-life pathways:

Step 3 vignettes often test the menu of options: a patient with non-survivable injury who is not brain dead can still potentially donate via DCD or, if circulation continues to time of death, via tissue donation only.

Conscientious objection: patients, families, and even individual clinicians may decline participation in donation on religious/moral grounds, but institutions must still refer to OPO.

Post-Process Care — Family Support and Recipient Follow-Up

— Immediate post-procurement: opportunity to view the body, receive a final goodbye, and a keepsake (often a heart-beat recording, handprint, or letter)

— Bereavement follow-up by the OPO at multiple intervals (typically 1, 3, 6, 12 months)

— Aftercare correspondence: donor families receive a letter describing in general terms which organs were transplanted and outcomes; identifying information protected

— Donor family ↔ recipient communication: facilitated through OPO and transplant center; anonymous letters first; direct contact only if both parties consent

— Memorial events, "Donate Life" ceremonies

— Lifelong immunosuppression: typically tacrolimus + mycophenolate + steroids

— Surveillance biopsies (heart, liver, kidney)

— Vaccinations: inactivated only post-transplant; complete live vaccines pre-transplant when possible

— Cancer screening intensified — skin (SCC), lymphoma (PTLD), cervical, anal

— Infection prophylaxis: TMP-SMX (PCP), valganciclovir (CMV), antifungals per protocol

— Cardiovascular risk management — leading cause of late mortality

— Encourage registry enrollment at the DMV, online, or in advance directives during routine health maintenance visits

— Address common myths (doctors won't try as hard, religion forbids it, you can't have an open casket — all false)

Step 3 management: During a Welcome to Medicare visit or routine adult preventive visit, asking patients about advance directives is standard. Including a brief mention of organ donor registration normalizes the conversation and increases registry uptake.

Follow-Up, Monitoring, and Health-System Metrics

— Donation rate: actual donors / donor potential (deaths meeting OPO criteria)

— Transplantation rate: organs transplanted / donor potential

— OPOs are tiered (Tier 1, 2, 3) and underperformers face decertification — drives systemic emphasis on early referral and authorization

— Conversion rate: actual donors / eligible deaths

— Timely referral rate: notification within 1 hour of trigger

— Authorization rate: donors authorized / approached

— Mandatory reporting of recipient outcomes to OPTN

— DTAC reviews suspected donor-derived disease transmissions

— Graft survival benchmarks: kidney 1-yr > 95%, liver 1-yr ~90%, heart 1-yr ~90%, lung 1-yr ~85%

— Persistent disparities: lower donation/transplant rates in Black, Hispanic, and Indigenous communities; targeted community engagement programs

— Live donor protections: National Living Donor Assistance Center, expanded job protection (FMLA), and prohibition of denying life/health insurance based on donation status

— Annual case review of every death for missed referrals

— In-services on brain death determination and family communication

— "Honor walks" at procurement to recognize donors

Board pearl: A hospital that fails to refer every imminent death or actual death to the OPO — even if the patient would clearly not qualify — is in violation of CMS Conditions of Participation. The OPO, not the hospital team, decides medical suitability.

Ethical, Legal, and Patient Safety Considerations

— Treating clinicians do not initiate donation conversations

— Physician declaring death is separate from the transplant team

— Informed consent for donation is obtained by trained OPO requestors

— Registered donor whose family objects: first-person authorization is legally binding; however, in practice OPOs often will not proceed against vigorous family opposition due to public-trust concerns. Step 3 answer: honor the patient's documented wish, but engage family supportively.

— Incarcerated patient: can donate (especially after death); living donation by prisoners is largely prohibited due to coercion concerns.

— Patient with prior verbal wish but no registry entry: surrogate may authorize on that basis.

— Suspicious deaths, pediatric deaths, homicides → medical examiner must release the body before procurement; almost always coordinated successfully

— Donation does not override autopsy obligations

— Selling organs is a federal felony (National Organ Transplant Act, 1984)

— All donor hospital costs after declaration transfer to OPO; family is never billed for donation-related care

— Hand-off from ICU to OPO/OR teams must include complete medication list, ABG trends, lines, and active issues — a frequently audited safety point

— Cross-clamp time and ischemic time documentation are critical

Step 3 management: A grieving family of a registered donor asks you to "stop the process." The correct answer is to express empathy, explain that their loved one made this decision in advance, and involve the OPO and chaplaincy/ethics for support — not to unilaterally cancel donation, and not to dismissively invoke the law.

Dead donor rule: organ recovery may not cause death; donors must be dead (DBD) or declared dead by circulatory criteria (DCD) before procurement. This is the ethical foundation of US transplantation and cannot be violated.

Mandatory reporting and ME cases:

High-Yield Associations and Rapid-Fire Facts

Board pearl: "Brain dead" = legally and medically dead, full stop. The ventilator supports organs, not a patient. This single concept anchors most Step 3 donation questions.

Uniform Anatomical Gift Act (UAGA): enacted in all 50 states; governs donor designation, surrogate hierarchy, and first-person authorization.

Uniform Determination of Death Act (UDDA): defines death as irreversible cessation of circulatory/respiratory function OR irreversible cessation of all functions of the entire brain, including the brainstem.

National Organ Transplant Act (NOTA, 1984): prohibits organ sale; created OPTN.

HOPE Act (2013): permits HIV+ to HIV+ organ transplantation under research protocol.

Required Request laws (1986): hospitals must refer to OPO; family doesn't have to be asked, the OPO must be notified.

Apnea test threshold: PaCO₂ ≥ 60 or rise of 20 above baseline.

No-touch period in DCD: typically 5 minutes of asystole (range 2–5).

Cold ischemic time ceilings: heart 4–6 h, lung 6–8 h, liver 12 h, pancreas 12 h, kidney 24–36 h (longer with machine perfusion).

MELD score allocates livers; LAS for lungs; CPRA for sensitized kidney recipients.

Most common cause of late death after transplant: cardiovascular disease (kidney, liver), CAV/chronic rejection (heart), bronchiolitis obliterans (lung).

Most common donor-derived transmission: bacterial (CMV-mismatch is most common viral consideration; rabies/LCMV are headline-grabbers but rare).

Religious positions: nearly all major religions permit donation; Jehovah's Witnesses accept transplants but decline transfusions; Orthodox Judaism has rabbinic variation around brain death acceptance.

Living kidney donor lifetime ESRD risk: small absolute increase (~0.5–1%) above matched non-donors; donors do not appear to have shortened life expectancy.

Pediatric brain death: requires two exams, intervals 24 h (neonate) or 12 h (older child).

Locked-in syndrome: NOT brain death — preserved consciousness and vertical gaze.

Board Question Stem Patterns

— Answer: Honor the registry designation; engage OPO and family support. Document, do not override the patient's first-person authorization.

— Answer: Discontinue sedation and allow sufficient time for clearance (or check drug levels) before brain death exam. Drug confounders invalidate the exam.

— Answer: OPO coordinator (or trained designated requestor), not the treating physician. Decoupling.

— Answer: Disclose PHS increased-risk donor status; risk of window-period transmission < 1/10,000; transplantation proceeds with informed consent.

— Answer: DDAVP/vasopressin + hypotonic IVF; goal Na < 155 to preserve liver graft suitability.

— Answer: Empathic explanation that the ventilator and medications are supporting the heart and organs; the brain — which controls breathing and consciousness — has irreversibly stopped, and that is death.

— Answer: Notify the OPO; tissue donation (corneas, bone, valves) is feasible even without organ donation.

Key distinction: Step 3 frequently tests what you, the physician, do next — not the medical science. The correct answer is almost always call the OPO, do not override registry, do not initiate the donation conversation yourself.

Stem 1: 28-year-old after MVC, GCS 3, fixed pupils, no brainstem reflexes, on the ventilator. The intensivist documents brain death after appropriate testing. The patient is a registered donor but the mother refuses. What is the most appropriate next step?

Stem 2: 65-year-old post-cardiac-arrest, day 4, no brainstem reflexes, on fentanyl and midazolam infusions. Team is ready to declare brain death. Best next step?

Stem 3: Imminent death patient on ventilator, devastating ICH, family considering withdrawal. Who initiates the donation conversation?

Stem 4: 45-year-old donor with history of IV drug use 6 months ago, HIV/HCV/HBV NAT negative. Recipient asks if it's safe.

Stem 5: Brain-dead donor develops polyuria 600 mL/hr, Na 158, dilute urine. Best management?

Stem 6: Family of brain-dead patient asks "If she's dead, why is her heart still beating?" Best response?

Stem 7: Patient dies in ED of MI; family asks about donation. Best step?

One-Line Recap

Organ donation is a federally regulated, ethically rigorous process anchored by the dead donor rule, mandatory OPO referral for every imminent or actual death, decoupling of the donation conversation from the treating team, and respect for first-person authorization — with the physician's role being to identify potential donors early, notify the OPO, optimize organ physiology after declaration of death, and support families compassionately through brain death or DCD pathways.

High-yield recap bullets:

Board pearl: When in doubt on a Step 3 stem about donation, choose the answer that calls the OPO, honors the donor registry, and supports the family — never the answer that has the primary team unilaterally cancel donation, advocate for it, or determine medical suitability.

Notify the OPO first — for every imminent death and every actual death. The OPO, not the hospital team, decides medical suitability and approaches the family. Failure to refer violates CMS Conditions of Participation.

First-person authorization is binding under UAGA. A registered donor's wishes are honored; the family is supported and informed, not asked for permission. If no registry entry, surrogate hierarchy applies (spouse → adult children → parents → siblings → guardian).

Brain death = legal death via UDDA: coma + absent brainstem reflexes + positive apnea test (PaCO₂ ≥ 60 or rise ≥ 20) after exclusion of confounders (hypothermia, drugs, NMB, metabolic). DCD = death by circulatory criteria after planned withdrawal, with a 5-minute no-touch period before procurement.

Decoupling is non-negotiable: the treating physician does not initiate the donation discussion, and the physician declaring death is separate from the transplant team — preserving trust, autonomy, and the integrity of the dead donor rule.
