Capacity and competence are two terms people often use interchangeably. However, they are distinctly different. Understanding capacity vs competence in healthcare is important because these differences directly affect resident rights, informed consent, and how decisions are made in senior living communities.

Competency refers to a person’s legal ability to make decisions, and a court determines it. It is a global assessment that affects all aspects of an individual’s legal rights, such as managing finances, signing contracts, or creating a will. If a court finds a person incompetent, it may appoint a guardian or conservator. In most cases, that legal status remains in place until the court changes it. Legal Clarity provides a helpful explanation of how competence is tied to legal authority and court involvement.

Capacity, on the other hand, is a clinical or functional assessment made by healthcare professionals. It helps determine whether an individual can make a specific decision at a particular time. Capacity is task-specific and can fluctuate depending on medical conditions, medications, or cognitive changes. DoveMed outlines how healthcare providers evaluate capacity and why it plays such an important role in resident care decisions.

There are four key elements when assessing capacity:

  1. Understanding – can the person comprehend relevant information about their condition and treatment options?
  2. Appreciation – can they recognize the consequences of their decisions based on personal values and goals?
  3. Reasoning – can they logically weigh the pros and cons of different options?
  4. Communication – can they clearly express their decision?

Capacity assessments are essential for informed consent because they help ensure residents understand the nature, risks, and benefits of medical interventions. If a resident lacks capacity, a surrogate decision-maker such as a legally appointed guardian or Durable Power of Attorney for medical decisions may step in on their behalf.

It is important to know the difference between these two terms and how it may impact your current practices. Even if a resident has the capacity to make decisions, we may not agree with their choices. That does not mean we get to override them. We are not the judge and jury. We must respect those choices unless there is an immediate risk of harm. In those situations, legal guidance should be sought as quickly as possible.

When we understand capacity vs competence in healthcare, we protect both resident autonomy and the integrity of care decisions. First, do no harm. Respect each resident’s right to make choices, even if they are not the choices we would make.

Stay well and stay informed!
