The Role of Advance Health Care Directives and Medical Decision-Making

Edington Law Firm, Inc. May 14, 2025

An advance health care directive (AHCD) plays a crucial role in making medical decisions when an individual is unable to express their wishes due to illness or incapacity. This legal document outlines an individual’s preferences for medical treatment, appointing someone to make decisions on their behalf if they can't do so themselves. 

At Edington Law Firm, Inc. in Modesto, California, I understand how important it is to have a clear and comprehensive advance health care directive as part of your overall estate plan. As an experienced estate planning attorney, I can guide you through the process of drafting and understanding the significance of this document.

While many people are familiar with the importance of a will or power of attorney, they may not fully realize the crucial role an advance health care directive plays in medical decision-making.

An AHCD not only offers guidance during medical emergencies but also provides peace of mind knowing that your medical choices will be respected. As you read further, I’ll go deeper into how an advance health care directive can be integrated into your estate plan and why it's such an essential tool.

What Is an Advance Health Care Directive?

An advance health care directive is a legal document that allows individuals to specify their health care preferences in advance of a medical crisis. The document typically includes two main components: a living will and a durable power of attorney for health care.

The living will outlines specific medical treatments a person wishes or doesn't wish to receive if they're unable to communicate their wishes. The durable power of attorney for health care designates an agent, often referred to as a health care proxy, who can make decisions on the person’s behalf in accordance with their desires.

Having an advance health care directive makes sure that your medical treatment aligns with your wishes, even when you're no longer able to make decisions. With this directive, your family and healthcare providers are provided with clear guidance regarding your preferences, which can prevent confusion or disagreements.

Understanding the components of an AHCD is key, and this will help you make informed choices, as discussed in the next section.

Components of an Advance Health Care Directive

An AHCD contains two vital elements: the living will and the durable power of attorney for health care. Each element serves a specific function, and together they form a comprehensive approach to medical decision-making when you're unable to express your wishes.

The living will communicates your preferences about specific treatments, such as life support, organ donation, and resuscitation. It provides instructions regarding what steps should or shouldn't be taken if you're in a terminal condition, persistent vegetative state, or incapacitated.

On the other hand, the durable power of attorney for health care designates someone to act on your behalf. This person can make decisions about medical treatment if you’re unable to do so. Some key factors to consider when choosing a proxy include:

  • Trustworthiness: The person must understand and respect your values and decisions regarding medical treatment.

  • Communication: Your proxy should be someone you can communicate openly with about your wishes and who will advocate for you when needed.

  • Availability: Ideally, your health care proxy should be someone who is easily accessible and able to make timely decisions on your behalf.

Having a durable power of attorney for health care, in addition to a living will, makes sure that someone will be there to make medical decisions based on your preferences. Once you’ve considered the components of an AHCD, it’s important to understand how these directives work in various medical situations.

How an Advance Health Care Directive Works in Different Medical Situations

An advance health care directive becomes essential when you're unable to communicate your wishes due to injury or illness. This could include situations like being in a coma, suffering from severe cognitive decline, or experiencing a terminal illness. 

In these circumstances, the instructions in your AHCD guide medical professionals in providing care in line with your desires.

For example, if you’re in a vegetative state with no hope of recovery, your living will may specify that you don't want life-sustaining treatments. Alternatively, if you’re unable to make decisions but are likely to recover, your appointed health care proxy would have the authority to make treatment choices on your behalf. 

Reviewing how your AHCD applies in various medical situations helps make sure that your wishes are respected during critical moments.

In some situations, your health care proxy may also need to make decisions about specific treatments that aren't outlined in your living will. This is why it’s important to discuss your preferences with your proxy in detail so they can act in your best interest. 

Legal Considerations for Creating an Advance Health Care Directive

Creating a valid advance health care directive requires a clear understanding of the legal requirements in your state. While the basic components of an AHCD are generally the same, the formalities may vary depending on local laws. For example, some states may require the document to be notarized or witnessed by specific individuals.

Additionally, the person you appoint as your health care proxy should be someone who is legally eligible to serve in this capacity. In most cases, your proxy can't be a medical provider involved in your care or someone who stands to benefit from your estate.

Working with an estate planning attorney makes sure that your advance health care directive complies with your state’s legal standards and is legally binding. 

An estate planning attorney can guide you through the process, making sure all legal formalities are properly met. The next section will explore how to effectively choose your health care proxy.

How to Choose a Health Care Proxy

Choosing the right person to serve as your health care proxy is one of the most important decisions you’ll make when preparing an advance health care directive. Your proxy will make critical decisions about your health care, so it’s essential that you select someone who is reliable, compassionate, and understands your wishes.

The ideal health care proxy should be someone who can make difficult decisions on your behalf while still honoring your values. Some factors to consider when selecting a proxy include:

  • Close knowledge of your medical history and preferences: The individual should be familiar with your overall health and medical treatment preferences.

  • Emotional maturity and decision-making ability: Your proxy should be able to handle difficult situations without being overwhelmed by emotions.

  • Comfort in discussing end-of-life care: Your proxy should be open to having frank discussions about your wishes for life-sustaining treatments.

Once you’ve selected your health care proxy, it’s important to have ongoing conversations to make sure that they’re clear about your desires. Now that you’ve selected your proxy, you’ll need to consider how to maintain and update your advance health care directive.

Maintaining and Updating Your Advance Health Care Directive

Like other parts of your estate plan, it’s important to regularly review and update your advance health care directive. Life circumstances change, and so do your preferences regarding medical treatment. Regular updates make sure that your directive remains in line with your current wishes.

Changes in health, family dynamics, or personal beliefs may require adjustments to your advance health care directive. For example, if your health status changes or your proxy becomes unavailable, you may want to appoint a new health care agent.

Additionally, as medical advancements occur, your treatment preferences may evolve as well. Regularly reviewing your AHCD with your estate planning attorney makes sure that the document reflects your latest intentions.

Some key considerations for maintaining your AHCD include:

  • Reviewing your directive every few years: Periodically checking your directive makes sure that it still reflects your wishes.

  • Informing your health care proxy of any updates: Make sure they're aware of any changes so they can act accordingly.

  • Discussing updates with your medical team: Notify your doctor about any modifications to your directives.

Keeping your advance health care directive current is an important part of making sure that your wishes are respected. By working with an estate planning attorney, you can have peace of mind knowing that your medical decisions are in good hands and legally protected.
