Introduction to Advanced Directives and Decision Making

Overview of Previous Class

We previously discussed key concepts surrounding advanced directives and the role of substitute decision-making in healthcare. The importance of these directives in ensuring patient autonomy and guiding medical decisions when patients are unable to articulate their wishes was emphasized.

Informed Consent Exceptions

Informed consent is a fundamental principle in healthcare, but there are many exceptions where individuals may be unable to provide it. This includes:

  • Children: Minor patients often require parental consent for treatment decisions.

  • Cognitive Impairment: Individuals with conditions such as dementia, severe mental illness, or developmental disabilities may lack the capacity to give informed consent.

  • Medical Emergencies: In situations where a patient is unconscious or incapacitated, healthcare providers may initiate treatment without consent to prevent harm.

Framework for Decision Making

Decision Making Hierarchy

Legal guidelines typically outline a hierarchy of decision-makers in the absence of informed consent:

  1. Spouse or partner

  2. Adult children

  3. Parents

  4. Siblings

  5. Other relatives or friends

  • The decision-makers should strive to make choices that align with the patient’s known values and previously expressed wishes when possible.

How to Decide

When the patient’s stated wishes are unknown, decisions should be made in what is deemed the best interest of the individual, considering factors such as their previous lifestyle preferences and quality of life.

Understanding Advanced Directives

Purpose

Advanced directives are legal documents that enable individuals to communicate their healthcare preferences ahead of time, especially concerning end-of-life care. They help ensure that a person's wishes are honored when they can no longer express them.

Legal Framework in Ontario

In Ontario, a specific advanced directive framework does not exist, leading to particular challenges:

  • Substitute decision-makers must consent to treatments at the time of the intervention, based on the patient’s current situation and not solely on past directives.

Philosophical Considerations on Past Wishes

Skeptical Challenge

A significant ethical question is raised regarding the relevance of past wishes if a patient can no longer recall or prioritize them.

  • For example: A patient may have once aspired to become a marine biologist but now has a different set of values or goals reflecting their current state.

Example with Dementia

Patients suffering from advanced dementia often face this dilemma, as they might not recall their prior preferences. This poses a tension between honoring past directives and prioritizing current well-being and comfort.

Clinical Cases and Ethical Dilemmas

Real-life clinical encounters illustrate how preferences evolve with cognitive decline:

  • A patient who was a lifelong vegetarian may suddenly desire meat, challenging previously established dietary directives.

  • Religious individuals may question past beliefs and rituals, bringing forth ethical dilemmas regarding adherence to historical directives in light of present circumstances.

Ronald Dworkin's Argument

Margot’s Case

Consider a hypothetical situation involving a woman named Margot, who has a living advance directive that articulates her wishes regarding end-of-life care and treatment.

  • Dilemma: Should clinicians adhere to Margot's past wishes, or should they prioritize her present state of contentment and quality of life?

  • Dworkin’s View: He argues that we should respect Margot's directives despite her current cognitive state, as they encapsulate her critical interests and true identity.

Concept of Interests in Decision Making

Experiential vs. Critical Interests

Dworkin distinguishes between two types of interests that should be considered in decision-making:

  • Experiential Interests: Emphasizing immediate experiences and pleasures (e.g., joy, comfort).

  • Critical Interests: Defining a person's identity, such as long-term goals and commitments (e.g., family, career aspirations).

  • Dworkin asserts that critical interests should take precedence over experiential interests when making healthcare decisions.

Conflict Between Past Wishes and Current Well-being

Moral Tension

If Margot is currently enjoying life and does not seem to prioritize her former wishes, should those desires be neglected? Various examples showcase how values may significantly shift due to cognitive degeneration, raising moral and ethical concerns.

Public Opinion and Legal Context

Public Support for Advance Directives

Surveys demonstrate substantial public support for advance directives and requests for Medical Assistance in Dying (MAID), emphasizing the importance of patient autonomy in healthcare settings.

Rebecca Dresser’s Counterarguments

Critique of Dworkin

Rebecca Dresser offers a counter-narrative, questioning the autonomy and validity of advanced directives:

  • Dresser argues for the prioritization of a patient's current self over past proclamations,

  • She challenges the idea that critical interests universally overshadow experiential interests, invoking philosophical debates about personal identity and continuity over time.

Theories of Personal Identity

Several philosophical theories have emerged regarding personal identity:

  • Body Theory: Centers on the physical body but faces challenges as cellular and bodily changes occur over time.

  • Brain Theory: Focuses on consciousness and memory, yet this too has limitations.

  • Psychological Connectedness: Proposed by theorist Jeff McMahon, suggesting individuals exist through psychological links and memories—an essential concept in considering how directives apply to those who have changed significantly.

Implications for Ethical Decision Making

Margot’s Existence

Dworkin’s perspective on psychological connectedness raises questions about Margot's identity. If she loses her connection to her past self, the ethical basis for respecting her advance directives may diminish.

Conclusion

A thorough understanding of personal identity complexities is vital in applying advanced directives within the scope of bioethics, ultimately influencing ethical decision-making processes in healthcare.

Summary of Class Learning Objectives

We recapped key points, including:

  • Definitions of autonomy, beneficence, and non-maleficence and how they relate to advanced directives and ethical decision-making in healthcare.
