What is the primary purpose of advance directives in patient care?

The primary purpose of advance directives in patient care is to indicate the form of treatment a patient is willing to accept in case of serious illness. Advance directives serve as legal documents that convey a patient's preferences regarding medical treatment when they are unable to communicate those wishes themselves, often due to incapacitation or a severe medical condition. This empowers patients to maintain some control over their healthcare decisions, ensuring that medical interventions align with their values and preferences.

In situations where patients face life-altering decisions, advance directives guide healthcare providers, ensuring that the treatments administered are consistent with the patient's desires. This not only helps to respect the patient's autonomy but also provides clarity for families and medical staff during emotionally charged situations.
