17.3 Surrogate Decision-Making, Advance Directives & Confidentiality
Key Takeaways
- Assessment of decisional capacity, competency and surrogate decision-making in the elderly is an enumerated blueprint topic.
- A health care agent named in a durable power of attorney takes precedence over the default statutory surrogate hierarchy.
- Substituted judgment asks what the patient would have wanted, and the best interests standard applies only when those wishes are unknown.
- Exceptions to confidentiality include mandatory reporting of certain infections, suspected abuse, and a serious threat of harm to an identifiable person.
- Physician orders for life-sustaining treatment are actionable medical orders that travel with the patient, distinct from an advance directive.
1. Surrogate Decision-Making & Advance Directives
When an adult patient loses decisional capacity, clinicians must identify a designated or default surrogate decision-maker and adhere to established decision-making standards.
A. Hierarchy of Decision-Making Standards
- Explicit Advance Directives (Living Wills, POLST / MOLST):
- Living Will: A written legal document specifying the patient's explicit preferences regarding life-sustaining interventions (intubation, feeding tubes, CPR, dialysis) in defined clinical scenarios (terminal illness, persistent vegetative state, end-stage irreversible condition).
- POLST / MOLST (Physician/Medical Orders for Life-Sustaining Treatment): Actionable medical orders signed by a clinician that translate patient preferences into immediate orders across healthcare settings (CPR status, intubation/mechanical ventilation limits, medical interventions [Full, Selective, Comfort-focused], artificial nutrition).
- Ethical Rule: Explicit, documented patient preferences always supersede surrogate opinions.
- Substituted Judgment Standard:
- Used when the patient lacks a written advance directive but has previously expressed values, religious beliefs, lifestyle goals, or verbal statements regarding medical care.
- Core Mandate: The surrogate must stand in the patient's shoes and make the exact decision that the PATIENT would have made if they could speak for themselves today ("What would your father want in this situation based on the life he lived and things he said?"), rather than what the surrogate desires.
- Best Interests Standard:
- Used ONLY when the patient's own values, preferences, and prior wishes are completely unknown (e.g., lifelong severe intellectual disability, orphaned adult, unrepresented estrangement).
- Core Mandate: The surrogate and healthcare team weigh the objective benefits and burdens of treatment from the perspective of a reasonable person to maximize the patient's net physical, emotional, and functional well-being.
B. Statutory Priority Hierarchy of Default Surrogate Decision-Makers
While state statutes vary slightly, the standard statutory hierarchy for appointing a default surrogate is:
- Designated Healthcare Proxy / Durable Power of Attorney for Healthcare (DPOA-HC) (appointed legally by the patient while having capacity),
- Court-Appointed Legal Guardian with specific healthcare authority,
- Spouse or legally recognized domestic partner,
- Adult Children (majority consensus among siblings),
- Parents,
- Adult Siblings,
- Close Friend or other surviving adult relatives who maintain regular contact and familiarity with the patient's values.
C. Unrepresented ("Unbefriended") Patients
For incapacitated patients who lack both decisional capacity and an available surrogate or advance directive:
- Emergency Care: Implied consent governs immediate life-saving care.
- Urgent/Non-Emergent Major Interventions: Require a formal Hospital Ethics Committee consultation, multi-disciplinary consensus, or an institutional two-physician independent sign-off.
- Major Long-Term Decisions (e.g., withdrawal of life support without prior wishes): Institutional legal petition for a court-appointed public guardian.
2. Confidentiality, HIPAA & Mandatory Reporting Exceptions
The Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule establishes federal protections for Protected Health Information (PHI). However, the duty of physician-patient confidentiality is not absolute and must yield when overriding public safety, individual welfare, or statutory legal mandates apply.

Protected PHI Mandatory Reporting
(Requires Patient Authorization) (Confidentiality Overridden)
• Clinical notes & diagnoses • Suspected Child Abuse / Neglect
• Laboratory & imaging data • Suspected Elder / Vulnerable Adult Abuse
• Billing & demographic info • Mandated Communicable Diseases (CDC/DOH)
• Sensitive history (drugs, sex) • Duty to Warn / Protect (Tarasoff)
• Impaired Drivers (Epilepsy, Syncope)
• Violent Penetrating Trauma (GSW, Stabs)
Mandatory Exceptions Overriding Patient Confidentiality
| Exception Domain | Legal / Statutory Trigger | Mandated Clinical & Reporting Action |
|---|---|---|
| Child Abuse or Neglect | Any reasonable suspicion of physical abuse, sexual abuse, emotional abuse, or severe neglect in a child (<18 years). | Immediate mandatory report to Child Protective Services (CPS) or local law enforcement. Proof is not required; suspicion suffices. Immunity from civil liability is granted for good-faith reporting. |
| Elder & Vulnerable Adult Abuse | Suspicion of physical abuse, financial exploitation, sexual abuse, abandonment, or caregiver neglect in adults aged >=60–65 or disabled vulnerable adults. | Mandatory report to Adult Protective Services (APS) or law enforcement. Note: Domestic violence in competent non-elderly adults is NOT universally reportable without patient consent unless weapons are involved. |
| Reportable Infectious Diseases | Laboratory confirmation or clinical diagnosis of communicable diseases posing severe public health threats. | Mandatory reporting to local/state Department of Health (DOH) and CDC. Examples: Tuberculosis (active or suspect), Syphilis, Gonorrhea, Chlamydia, HIV, Measles, Hepatitis A/B/C, Meningococcal disease, Pertussis, Rabies, foodborne pathogens (Salmonella, E. coli O157:H7). Partner notification is handled via public health contact tracing. |
| Duty to Warn / Protect (Tarasoff Ruling) | A patient makes an explicit, credible, and imminent threat of serious physical harm or death against an identifiable third party (or specific group). | Obligation to notify law enforcement immediately AND take reasonable steps to warn the intended victim. Overrides confidentiality. |
| Impaired Drivers | Documented uncontrolled seizure disorder, recurrent syncope, severe cognitive impairment, or severe visual deficit impairing driving safety. | Mandatory or permissive state DMV reporting depending on state jurisdiction; clinician must counsel patient to cease driving immediately. |
| Violent Penetrating Trauma | Presentation with gunshot wounds, stab wounds, or severe injuries resulting from criminal violence. | Mandatory reporting to local law enforcement agencies. Medical stabilizing care precedes police interviews. |
An 82-year-old woman with severe vascular dementia and stage IV chronic kidney disease is admitted to the hospital with severe aspiration pneumonia complicated by acute respiratory failure and septic shock. She has no decision-making capacity. Two years ago, while fully competent, she executed a legally valid living will and durable power of attorney for healthcare designating her adult son as healthcare proxy. The living will explicitly states: 'If I develop advanced irreversible dementia or a terminal illness, I do not want endotracheal intubation, mechanical ventilation, cardiopulmonary resuscitation, or artificial feeding tubes; I desire only comfort-focused care.' However, the patient's adult daughter arrives at the hospital, asserts that she cannot bear to lose her mother, and demands that the medical team perform endotracheal intubation and transfer her mother to the intensive care unit for full invasive support. The designated healthcare proxy (the son) is present and affirms his mother's written wishes. What is the most appropriate next step in clinical decision-making?
