Healthcare proxy

A healthcare proxy, also known as a health care power of attorney, is a legal document executed by a competent adult that appoints a designated agent—typically a trusted family member, friend, or advisor—to make medical decisions on the principal's behalf if the principal becomes incapacitated and unable to communicate preferences due to conditions such as coma, dementia, or severe illness.^[1]^[2]^[3] The proxy grants the agent authority to consent to, refuse, or withdraw treatments, including diagnostic procedures, surgeries, and life-sustaining interventions like mechanical ventilation or artificial nutrition, guided by the principal's previously expressed wishes, values, or, absent clear guidance, the agent's determination of the principal's best interests.^[4]^[5] Unlike a living will, which outlines specific treatment preferences in advance without naming a decision-maker, a healthcare proxy provides flexibility for the agent to adapt to unforeseen circumstances, making it a preferred component of broader advance care planning in jurisdictions recognizing it.^[6]^[7] Enacted under state-specific statutes—such as New York's Public Health Law or Massachusetts' proxy form requirements—the document typically requires no witnesses or notarization in many U.S. states but must be presented to health care providers to activate upon verified incapacity, thereby aiming to prevent disputes among family members and ensure decisions align with the principal's autonomy rather than default hospital protocols or hierarchical surrogacy laws.^[8]^[9] While effective in reducing unwanted interventions, empirical studies indicate proxies can face ethical challenges, including conflicts over resource allocation or overriding aggressive care in terminal cases, underscoring the causal importance of clear principal instructions to mitigate agent burden and legal contests.^[10]

Definition and Purpose

Core Elements

A healthcare proxy is a legal document executed by a competent adult, known as the principal, to designate another individual, termed the agent or proxy, to make medical decisions on the principal's behalf in the event of incapacity.^[2]^[7] This instrument ensures continuity of care by authorizing the agent to consent to, refuse, or withdraw treatments, access medical records, and communicate with providers, thereby implementing the principal's known preferences under the standard of substituted judgment.^[11]^[1] Essential components include the explicit nomination of a primary agent, typically an adult relative or trusted associate over age 18 who demonstrates reliability and familiarity with the principal's values.^[12]^[13] Many forms also require or recommend designating at least one alternate agent to assume authority if the primary is unavailable or unwilling, preventing reliance on default surrogacy laws that may conflict with the principal's intent.^[14] The document must specify the scope of authority, which generally encompasses all health care matters except those explicitly limited, such as euthanasia where prohibited by law.^[15]^[16] Activation hinges on a determination of the principal's incapacity, often certified by one or two physicians based on inability to understand or communicate treatment decisions, without requiring terminal illness.^[2]^[17] For validity, the principal must sign the form while mentally competent, with attestation by two disinterested witnesses in jurisdictions like New York, though notarization is unnecessary and some states accept un-witnessed documents if compliant with uniform acts.^[1]^[18] Unlike a living will, which outlines specific treatment directives, the proxy emphasizes flexible decision-making guided by prior discussions of the principal's wishes, enhancing adaptability to unforeseen circumstances.^[6]

Relation to Patient Autonomy and Substituted Judgment

A healthcare proxy upholds patient autonomy by allowing a competent individual to prospectively select a surrogate decision-maker who is familiar with their values, thereby extending the patient's self-determination into periods of incapacity. This mechanism contrasts with default surrogate hierarchies imposed by statute, as the designated proxy is chosen based on the patient's trust in their ability to represent personal preferences accurately. Legal and ethical frameworks, such as those outlined by the American Medical Association, emphasize that advance designation respects the core principle of autonomy, enabling patients to avoid unwanted interventions or omissions aligned with their worldview.^[19]^[20] Central to the proxy's role is the substituted judgment standard, which mandates that the surrogate decide as the patient would have, drawing on evidence of the patient's prior statements, beliefs, or conduct rather than the surrogate's own views or a generalized best-interests assessment. This approach prioritizes fidelity to the patient's hypothetical choice, treating the proxy as an extension of the patient's agency rather than an independent authority. For instance, if a patient had expressed aversion to life-sustaining measures in certain scenarios, the proxy must adhere to that stance, even if it conflicts with prevailing medical opinion. Courts and statutes in jurisdictions like Florida explicitly endorse this standard for incapacitated patients with designated proxies, aiming to minimize deviations from the patient's authentic preferences.^[21]^[22]^[23] The interplay between the healthcare proxy and substituted judgment reinforces causal continuity in decision-making, as the proxy's knowledge—gained through relational history—serves as the evidentiary basis for inferring the patient's wishes, though accuracy depends on the quality of prior communications. When substituted judgment cannot be applied due to insufficient information about the patient's views, surrogates may revert to a best-interests standard, which evaluates objective benefits like survival probability and quality of life but risks overriding subtle patient-specific factors. Studies highlight inconsistencies in surrogate predictions, with accuracy rates varying from 60-80% in simulated scenarios, underscoring the empirical limitations of relying solely on proxies without complementary living wills or detailed discussions.^[24]^[25]^[26]

Legal Frameworks

United States Variations

In the United States, healthcare proxy instruments—also termed durable powers of attorney for health care, medical powers of attorney, or advance healthcare directives—are regulated exclusively by state statutes, leading to jurisdictional differences in terminology, execution formalities, and operative scope.^[27] All fifty states and the District of Columbia authorize such proxies to empower a designated agent to make healthcare decisions upon the principal's incapacity, typically prioritizing the principal's known wishes or best interests. However, states diverge in default surrogate hierarchies absent a proxy; for instance, some prioritize spouses automatically, while others rank adult children or parents higher in certain scenarios.^[28] Execution requirements vary significantly: most states mandate two disinterested witnesses, but some, like California, permit notarization as an alternative, while New York requires two witnesses without notarization and no statutory living will form.^[29] Age eligibility for principals and agents generally stands at 18, though Alabama and Nebraska require 19.^[2] Proxies activate upon verified incapacity, often via physician certification, but thresholds for "incapacity" differ, with some states specifying terminal conditions or persistent vegetative states.^[30] Eligibility restrictions on agents also differ; several states bar those with direct financial interests in the principal's death, such as creditors or heirs, to mitigate conflicts, while others impose no such presumptions but allow judicial review.^[31] Authority typically excludes euthanasia or mental health commitments, though scopes expand in states adopting broader substituted judgment standards.^[27] Interstate recognition remains inconsistent: while many states honor out-of-state proxies resembling their own forms, others require re-execution or disregard non-compliant documents, complicating portability for mobile individuals.^[29] The Uniform Health-Care Decisions Act of 1993, aimed at standardization, has been adopted or influenced laws in over 20 states, but the 2023 revision—incorporating supported decision-making and electronic execution—has seen limited uptake, with Delaware as the first adopter in 2024 and others considering it amid ongoing fragmentation.^[32]^[33]

International and Comparative Approaches

In Canada, healthcare proxies are embedded within provincial legislation on powers of attorney for personal care, which empower the designated agent to make health-related decisions, including consent to treatments, when the principal lacks capacity. These instruments vary by province; for instance, Ontario's Substitute Decisions Act (1992) requires the attorney to act in accordance with the principal's expressed wishes or best interests, with hierarchy defaults to spouses or close relatives if no proxy is appointed. Similarly, in British Columbia, Representation Agreements under the Representation Agreement Act (1996) allow for routine health care decisions by a representative, but exclude certain life-sustaining treatments unless specified. Australia employs state-specific enduring guardianships or medical powers of attorney, which authorize agents to make health and lifestyle decisions upon the principal's incapacity, often requiring medical certification to activate. In Victoria, the Powers of Attorney Act 2014 mandates that enduring powers for health decisions be witnessed by a medical practitioner and prioritize the principal's values and beliefs, with tribunals overseeing disputes. Queensland's Powers of Attorney Act 1998 similarly allows for advance health directives alongside proxy appointments, emphasizing substituted judgment over best interests where instructions exist. In continental Europe, mechanisms blend proxies with living wills, often demanding notarization for validity. Germany's Patientenverfügung (advance directive under the Patientenrechtegesetz of 2013) complements the Vorsorgevollmacht (healthcare proxy), enabling a trusted person to consent to treatments or access records while bound by the principal's documented preferences; proxies must be registered for enforceability in care settings. France's mandat de protection future (introduced by the Loi n° 2007-308 of 2007 and reformed in 2016) appoints a mandatory to handle health and property upon judicial or medical confirmation of incapacity, requiring notarial authentication and periodic reviews to prevent abuse. Japan exhibits a family-centric approach to surrogate decision-making, with limited reliance on formal proxies; cultural norms favor consensus among relatives, typically led by the eldest son, over individual directives, as evidenced by surveys showing low advance directive completion rates (under 10% in some cohorts) and surrogates prioritizing harmony and physician input. The Act on Advance Directives (proposed but not fully enacted as of 2021) aims to formalize written instructions, yet clinical practice often defaults to substituted judgment via family under the Medical Care Act.^[34] Comparatively, while U.S. proxies emphasize patient autonomy through broad delegation, international variants impose stricter formalities—such as mandatory witnessing or registration—to mitigate risks of undue influence, reflecting divergent cultural weights on individualism versus collective familial duty; cross-border recognition remains inconsistent, often necessitating re-execution under local law.^[35]

United Kingdom Framework

In the United Kingdom, the legal framework for authorizing a proxy to make healthcare decisions derives primarily from the Mental Capacity Act 2005, which establishes principles for assessing mental capacity and making decisions in the best interests of individuals lacking capacity to decide for themselves.^[36] The Act presumes capacity in adults unless proven otherwise through a functional test applied to specific decisions, and it prioritizes the least restrictive option while empowering advance planning.^[37] Under this framework, a "healthcare proxy" equivalent is achieved via a Lasting Power of Attorney (LPA) for health and welfare, allowing a donor (the individual granting authority) to appoint one or more attorneys to make decisions about medical treatment, personal care, and residence if the donor later lacks capacity.^[38] The health and welfare LPA must be created while the donor has capacity, signed in the presence of a certificate provider (typically a professional confirming understanding), and registered with the Office of the Public Guardian before use, a process that takes approximately 8-10 weeks. Unlike financial LPAs, health and welfare versions do not activate until the donor lacks capacity, as determined by healthcare professionals, though the donor may specify earlier involvement for non-binding guidance.^[39] Attorneys are granted authority to consent to or refuse treatments on the donor's behalf, except for life-sustaining measures unless explicitly stated in the LPA document; in such cases, doctors must follow the donor's prior wishes if an advance decision to refuse treatment (ADRT) exists, potentially overriding the attorney.^[40] Attorneys must adhere to the Act's best interests checklist, consulting the donor's past and present wishes, beliefs, values, and input from relevant others, while avoiding conflicts of interest.^[41] For serious medical treatments, clinicians retain a duty to act in the patient's best interests and may seek Court of Protection approval if disputes arise or if the treatment involves restraint or deprivation of liberty under the Mental Capacity Act's Deprivation of Liberty Safeguards (now largely replaced by the Liberty Protection Safeguards under the 2018 amendments).^[42] This framework applies across England and Wales, with analogous but distinct provisions in Scotland (via the Adults with Incapacity (Scotland) Act 2000) and Northern Ireland (via the Mental Capacity Act (Northern Ireland) 2016), emphasizing substituted judgment aligned with the individual's known preferences over purely objective best interests.^[43]

Appointment Process

Eligibility and Capacity Requirements

A competent adult, typically defined as an individual aged 18 years or older, may appoint a healthcare proxy agent, with presumptive competence unless evidence demonstrates otherwise.^[2]^[11] In certain jurisdictions, such as New York, emancipated minors who are married or have children may also qualify to execute a proxy, reflecting statutory recognition of their legal autonomy in medical matters.^[44] To validly appoint an agent, the principal must possess decisional capacity, meaning the ability to comprehend the document's purpose, appreciate its consequences for future healthcare decisions, rationally evaluate the choice of agent, and communicate that choice consistently.^[9] Capacity is assessed through clinical evaluation focusing on cognitive function, absence of delusions influencing the decision, and understanding of the agent's role in substituted judgment or best interests standards.^[45] Eligibility for serving as a healthcare proxy agent generally requires the appointee to be an adult aged 18 or older in most U.S. states, with exceptions in Alabama and Nebraska mandating age 19.^[2] The agent must be willing and able to act, often a family member, close friend, or trusted individual, but cannot typically be the principal's attending physician, healthcare facility employee, or other conflicted parties to avoid undue influence.^[46] No formal licensure or expertise is required, prioritizing relational trust over professional qualifications, though the agent assumes fiduciary duties to act in alignment with the principal's known wishes.^[47] State laws may impose additional restrictions, such as prohibiting the agent from having financial interests that could bias decisions, ensuring impartiality in end-of-life or treatment choices.^[48]

Selection and Documentation Procedures

The selection of a healthcare proxy requires the principal to possess decision-making capacity and choose an adult of sound mind, typically aged 18 or older, though Alabama and Nebraska mandate a minimum age of 19.^[2] Prohibited appointees include healthcare providers treating the principal, their spouses or employees, facility operators or owners, or any designated evaluators or guardians to avoid conflicts of interest.^[2] Principals should evaluate candidates based on their willingness to discuss sensitive medical topics, demonstrated reliability, ability to navigate family disagreements, and practical availability, such as geographic proximity for timely involvement.^[2] Appropriate selections often include spouses, adult children, siblings, close friends, neighbors, or attorneys, with the designation of at least one alternate proxy recommended to ensure continuity if the primary is unavailable or unwilling.^[2] Before formalizing the appointment, principals must engage in detailed conversations with the chosen proxy about personal values, preferred treatments, and hypothetical scenarios, including end-of-life care, to enable substituted judgment aligned with the principal's autonomy.^[49]^[2] Documentation proceeds via a state-specific legal form, such as a durable power of attorney for health care or healthcare proxy designation, which outlines the proxy's authority and any instructions.^[2] The principal must sign and date the form, with execution requirements varying by jurisdiction: most states require two disinterested adult witnesses, while some additionally or alternatively demand notarization; for example, New York requires only two witnesses without notarization or legal counsel.^[2]^[1] Upon completion, copies should be provided to the proxy, primary care providers, hospitals, and retained in the principal's records for accessibility during incapacity.^[2] State forms are often available from health departments or online resources without attorney involvement.^[2]

Authority and Responsibilities

Granted Powers

A healthcare proxy, also known as a health care agent or medical power of attorney, is typically vested with broad authority to make health care decisions on behalf of the principal upon determination of incapacity, mirroring the decisions the principal would make if competent.^[50] This includes consenting to or refusing diagnostic procedures, therapeutic treatments, medications, and surgical interventions.^[1] In jurisdictions like Massachusetts, the agent holds the power to exercise "any and all health care decisions" the principal could personally authorize, encompassing routine care as well as complex interventions.^[50] The proxy's authority extends to end-of-life matters, such as approving or declining life-sustaining treatments, mechanical ventilation, or artificial nutrition and hydration when aligned with the principal's known wishes or best interests.^[2] Decisions regarding admission to hospitals, nursing homes, or hospice facilities fall within this scope, as does arranging for home health services or palliative care.^[51] The agent may also access confidential medical records, consult with physicians, and authorize mental health treatments, including involuntary commitments in some states where explicitly permitted.^[52] Proxy powers are activated only upon verified incapacity, typically certified by one or two physicians, and must prioritize substituted judgment—decisions reflecting the principal's expressed values—over the agent's personal views.^[53] While comprehensive, this authority excludes euthanasia, experimental procedures without ethics review, or organ donation unless separately specified in the proxy document or advance directive.^[54] State statutes, such as New York's Public Health Law, affirm the proxy's role in ensuring continuity of care without overriding statutory protections like those for minors or competent patients.^[8]

Boundaries and Ethical Constraints

Healthcare proxies possess authority circumscribed by statutory limits and the principal's documented instructions, generally extending only to decisions the patient could lawfully make if competent, such as consenting to or withholding routine, experimental, or life-sustaining treatments, but excluding acts prohibited by law.^[55] In most U.S. jurisdictions, this precludes authorization of euthanasia or physician-assisted suicide, which remain illegal except in a minority of states with permissive statutes requiring patient competence, thereby imposing a firm legal boundary on proxies to avoid endorsing unlawful terminations of life.^[56] Authority activates solely upon verified patient incapacity, typically determined by attending physicians, and terminates upon capacity restoration, patient death, or explicit revocation, preventing indefinite or posthumous exercise.^[55] Proxies also cannot override prior patient refusals of care without judicial intervention, nor access restricted protected health information, such as substance use records, if the patient had withheld consent under laws like HIPAA.^[55] Ethically, proxies must adhere to the substituted judgment standard, reconstructing decisions based on the patient's ascertainable values, prior statements, and preferences rather than the proxy's own moral framework or inclinations, to preserve autonomy.^[20] Where such preferences remain unknown, the best interests criterion applies, weighing prospective benefits against burdens like pain, functional impairment, and quality of life, without deference to extraneous factors such as family convenience or resource allocation.^[20] Conflicts of interest—financial, emotional, or relational—undermine legitimacy, obligating proxies to recuse or face challenge by physicians or courts if decisions deviate from patient-centric reasoning; ethical guidelines emphasize impartiality to mitigate risks of abuse or overreach.^[55] Physicians retain oversight, assessing proxy actions against these standards and escalating disputes legally when necessary to safeguard against deviations.^[57]

Historical Context

Early Developments

The concept of the healthcare proxy, formally known as a durable power of attorney for health care, emerged in the United States as an extension of early advance directive mechanisms aimed at preserving patient autonomy amid technological advances in life-sustaining treatments during the mid-20th century.^[58] Precursors included living wills, first proposed in 1967 by the Euthanasia Society of America and elaborated by attorney Luis Kutner in a 1969 Indiana Law Journal article, which sought to document refusals of extraordinary measures in terminal illness but proved rigid and limited in scope.^[58] These instruments addressed gaps exposed by high-profile cases, such as the 1976 New Jersey Supreme Court ruling in In re Quinlan, which affirmed a right to withdraw ventilator support from a comatose patient via substituted judgment by family, underscoring the need for designated surrogates over ad hoc family involvement.^[59] By the early 1980s, limitations of living wills—such as their narrow applicability to terminal conditions and inability to adapt to evolving medical scenarios—prompted innovation toward proxy appointment. The President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research, in its March 1983 report Deciding to Forego Life-Sustaining Treatment, explicitly endorsed durable powers of attorney for health care, recommending that competent adults appoint trusted agents to interpret and execute wishes flexibly when incapacity arises.^[59] This built on existing durable powers for financial matters, first statutorily recognized in Virginia in 1954, adapting agency law principles to medical contexts where decisional voids could prolong unwanted interventions.^[58] California pioneered statutory recognition of the healthcare proxy with the Durable Power of Attorney for Health Care Decisions Act, enacted in 1983 on recommendation of the California Law Revision Commission, marking the first state-level authorization for such instruments.^[60] The law empowered principals to designate agents with authority to consent to or refuse treatments, including life-sustaining ones, effective upon verified incapacity, thereby shifting from prescriptive directives to relational delegation.^[61] This development addressed ethical concerns over medical paternalism, as evidenced in contemporaneous surveys of healthcare professionals indicating readiness for proxy mechanisms to align decisions with patient values.^[62] Initial adoption emphasized witnessing requirements and revocation safeguards to prevent abuse, setting precedents for nationwide expansion.^[63]

Key Legislative Milestones

In 1983, California became the first state to enact legislation specifically authorizing a durable power of attorney for health care, allowing competent adults to appoint an agent to make medical decisions in the event of incapacity.^[58] This statute marked a pivotal shift from earlier living will laws, which focused primarily on refusing life-sustaining treatment, by empowering proxies to exercise broader substituted judgment based on the principal's known wishes.^[58] The federal Patient Self-Determination Act (PSDA), enacted on November 5, 1990, as part of the Omnibus Budget Reconciliation Act, required Medicare- and Medicaid-participating facilities to inform patients of their rights to execute advance directives, including healthcare proxies, and to document such directives in medical records.^[64] This law significantly accelerated state-level adoption of proxy statutes by mandating education and non-discrimination based on directive status, though it did not create uniform proxy authority.^[65] In 1993, the National Conference of Commissioners on Uniform State Laws promulgated the Uniform Health-Care Decisions Act (UHCDA), providing a model statute that integrated healthcare proxies, living wills, and surrogate decision-making hierarchies to promote consistency across states. The UHCDA emphasized proxy authority to consent to or refuse treatments aligned with the principal's preferences, influencing enactments in states like Maine, Mississippi, and New Hampshire, though full adoption remained limited to about a dozen jurisdictions by the early 2000s.^[66] New York's Health Care Proxy Law, effective January 18, 1991, exemplified early state-specific codification, permitting simple proxy appointments without requiring detailed treatment instructions.^[67]

Controversies and Debates

Ethical Tensions in Decision-Making

Ethical tensions in healthcare proxy decision-making often stem from the conflict between the substituted judgment standard, which prioritizes inferring and honoring the patient's prior autonomous preferences, and the best interests standard, applied when such preferences are unknown or ambiguous, focusing instead on objective medical benefits weighed against burdens.^[20] Proxies must navigate this duality, as empirical studies indicate surrogates accurately predict patient wishes only about 68% of the time, with deviations arising from incomplete knowledge of the patient's values or evolving circumstances.^[68] A key dilemma emerges when proxies confront advance directives, such as living wills, that appear misaligned with current clinical realities; for instance, ethicists have contended that overriding such directives may be ethically justified if new evidence suggests the patient's original intent was provisional or if rigid adherence would impose undue suffering, though this remains debated due to risks of proxy bias introducing subjective interests.^[69] In end-of-life ICU cases, this tension manifests in disputes over withdrawing mechanical ventilation or nutrition, where proxies balancing sanctity-of-life imperatives against futility assessments frequently experience moral distress, with surveys showing up to 80% reporting persistent guilt or second-guessing post-decision.^[57]^[70] Interpersonal conflicts compound these issues, particularly when family members disagree with the designated proxy or among themselves, leading to ethical standoffs resolved variably through ethics consultations or courts; data from U.S. hospitals reveal such disputes in 15-20% of surrogate scenarios, often rooted in divergent cultural or religious views on suffering and death rather than purely medical facts.^[71] Proxies also face inherent conflicts of interest, as their emotional ties or personal values may unconsciously skew toward prolongation of life, evidenced by research showing surrogates opt for more aggressive interventions than patients themselves would in 25-30% of hypothetical scenarios. These tensions underscore the causal role of inadequate prior communication in eroding decision fidelity, with institutional analyses recommending proactive clarification of proxy roles to mitigate overrides driven by regret rather than evidence.^[72]

Empirical Evidence on Effectiveness and Failures

Studies indicate that healthcare proxies contribute to reduced use of life-sustaining treatments among incapacitated patients. A 2010 analysis of seriously ill hospitalized adults found that those with advance directives, including designated proxies, were less likely to receive aggressive interventions such as mechanical ventilation or CPR compared to those without, with proxy involvement correlating to earlier shifts toward comfort care.^[73] Similarly, patients with documented proxies experience lower rates of hospital death and intensive care unit admissions at end-of-life, suggesting proxies enable more goal-concordant care in resource-intensive settings.^[74] However, empirical assessments reveal limitations in proxies' ability to accurately reflect patient preferences. A systematic review of surrogate decision-making accuracy across multiple studies reported average concordance rates of approximately 68% for treatment preferences, with rates seldom exceeding this threshold even among spouses or close relatives, indicating frequent deviations from substituted judgment standards.^[75] In specific end-of-life scenarios, such as preferences for decision control or acceptable health outcomes, proxy predictions aligned with patient wishes in only 47% to 52% of cases, highlighting systematic overestimation of patients' willingness for aggressive care.^[76] Failures often stem from incomplete knowledge of patient values or emotional biases influencing proxies. Research on substituted judgment shows poor agreement between proxies and patients on hypothetical medical decisions, with accuracy declining for nuanced choices like pain management versus life prolongation, leading to overtreatment in up to 40% of mismatched cases.^[77] Additionally, when proxies and advance directives conflict, clinical decisions more frequently follow proxy interpretations, potentially overriding written instructions and resulting in care misaligned with documented wishes, as observed in retrospective reviews of incapacitated elderly patients.^[78] These discrepancies underscore risks of proxy decisions amplifying family conflicts or prolonging futile treatments absent robust prior discussions.

Criticisms of Overreach or Inadequacy

Criticisms of healthcare proxy mechanisms often highlight risks of overreach, where designated surrogates exploit their authority to impose decisions misaligned with patient interests, potentially enabling abuse. Analysis of over 400 substantiated elder abuse cases across six U.S. counties revealed that 47% involved surrogates such as power-of-attorney holders or guardians, predominantly family members, with polyvictimization (multiple abuse types) common and nearly 25% featuring prior abuse reports.^[79] Such findings underscore vulnerabilities in community-dwelling older adults dependent on surrogates, where healthcare choices may serve perpetrators' motives—financial, emotional, or otherwise—rather than beneficence, prompting calls for enhanced oversight like mandatory reporting or judicial review in high-stakes decisions.^[80] Surrogates' tendency to project personal biases exacerbates overreach, particularly when proxy authority conflicts with advance directives like living wills. Empirical reviews show surrogates accurately predict patient preferences only 68% of the time, yet legal frameworks in states like Georgia prioritize proxy decisions over documented wishes, potentially allowing imposition of aggressive treatments against prior expressions.^[81]^[82] This substitution of judgment risks ethical breaches, as family dynamics or unrealistic prognoses lead to prolonged suffering or resource misuse, with limited empirical validation of proxies' fidelity to substituted judgment standards. Conversely, inadequacies arise from proxies' frequent failure to mirror patient wishes, rooted in predictive inaccuracies and contextual gaps. A systematic review of 16 studies confirmed surrogates' 68% accuracy in forecasting treatment preferences, unchanged by patient designation of the surrogate or prior discussions, indicating inherent limitations in human judgment under stress.^[81] In critical care, discrepancies escalate to 46% for high-risk scenarios, with surrogates exhibiting poor agreement (kappa 0.03–0.41) on consents patients might endorse or reject differently.^[83] Emotional burdens on surrogates further distort decisions, often favoring interventionist approaches over patient autonomy, as evidenced by mismatches in end-of-life choices where families override known preferences for withholding care.^[84] These patterns question proxies' reliability without supplementary tools like preference predictors, highlighting systemic gaps in training and documentation to bridge empirical shortfalls.

Practical and Empirical Insights

Implementation Challenges

Low completion rates hinder effective implementation of healthcare proxies, with only 36.7% of U.S. adults having completed any form of advance directive, including proxy designations, based on a meta-analysis of 150 studies encompassing 795,909 individuals.^[85] Among older adults, over 65% lack a healthcare proxy on file, exacerbating risks during incapacity.^[86] Barriers include limited knowledge, varying by ethnic and racial groups, and complex execution requirements such as mandatory witnesses or notarization in 48 states, which invalidate documents otherwise.^[87]^[88] Family conflicts frequently undermine proxy decisions, correlating with reduced accuracy in substituted judgments for end-of-life care (F[1,198] = 4.479, p = 0.036).^[89] Spousal proxies demonstrate higher accuracy (mean = 0.10) compared to adult children (mean = 0.56; p = 0.007), as non-spousal relatives may prioritize personal beliefs over the principal's wishes.^[89] Disagreements between proxies and other family members are common in end-of-life scenarios, often requiring physician mediation and escalating emotional strain without clear resolution mechanisms.^[71] In clinical settings, honoring proxies faces hurdles from inconsistent provider awareness and jurisdictional variations; for instance, 35 states prohibit oral directives, complicating urgent activations.^[88] While proxy opinions influence physicians' decisions (odds ratio 7.9, p < 0.001), medical professionals retain substantial sway, particularly when directives contradict proxy views, leading to overrides or delays.^[74]^[90] Poor document accessibility in emergencies and restrictions barring clinicians as agents in 37 states further impede seamless implementation, sometimes resulting in legal challenges or substituted default surrogates.^[88]^[91]

Outcomes and Societal Impact

Empirical studies indicate that healthcare proxies, as part of advance care planning, are associated with reduced use of life-sustaining treatments at end-of-life, with patients designating proxies less likely to receive aggressive interventions such as mechanical ventilation or ICU admission compared to those without.^[73] ^[74] However, surrogate decision-makers, including designated proxies, demonstrate limited accuracy in predicting or adhering to patients' prior wishes, with meta-analyses reporting concordance rates of only 58% to 68%, often influenced by surrogates' own values or emotional factors rather than strict substituted judgment.^[92] ^[75] Prevalence of healthcare proxy completion in the United States remains low, with approximately 36.7% of adults having any form of advance directive, though specific proxy designations are rarer, affecting around 14% in home health care populations and showing completion rates as low as 31.5% even after counseling interventions.^[85] ^[93] ^[94] This underutilization leads to reliance on default surrogate laws, where family members or court-appointed guardians make decisions, potentially resulting in higher rates of unwanted treatments due to conflicts or lack of prior guidance.^[87] On healthcare costs, evidence is inconsistent: some analyses link proxy-inclusive advance directives to lower Medicare expenditures at end-of-life, particularly in high-spending regions, with reductions tied to decreased hospital deaths and resource-intensive care, saving up to thousands per decedent.^[95] ^[96] ^[97] Others find no overall association with reduced spending, suggesting that while proxies may limit certain interventions, they do not consistently offset broader utilization patterns or substitute costs elsewhere.^[98] ^[99] Societally, healthcare proxies promote patient autonomy by enabling personalized decision-making amid incapacity, potentially alleviating family burdens and conflicts during crises, though low completion exacerbates disparities, with lower socioeconomic status, Hispanic ethnicity, and limited trust in healthcare systems correlating to reduced uptake.^[94] ^[100] Proxy laws have unintended effects, such as occasionally hindering real-time patient-proxy communication when rigid interpretations prevail, and their limited empirical impact on systemic outcomes underscores gaps in education and implementation.^[88] Overall, while proxies facilitate less invasive care in documented cases, widespread adoption challenges and surrogate inaccuracy temper their role in transforming end-of-life practices or achieving broad cost efficiencies.^[101]
