Can a patient refuse treatment even if it is life-saving?

A patient does have the right to refuse treatment, even if that treatment is considered life-saving, provided they are deemed competent to make informed decisions about their own health care. Informed consent is a fundamental principle in medical ethics and patient rights, indicating that patients must have the autonomy to make choices regarding their treatment, including the option to decline.

Competency implies that the patient understands the nature of their illness, the proposed treatment, the risks involved, and the consequences of not receiving treatment. When individuals are competent, they can make these decisions based on their values, beliefs, and preferences, which might include the desire to refuse certain medical interventions even if those could extend their life.

In contrast, the other choices imply restrictions on a patient's autonomy that do not align with the principles of informed consent and patient rights. For example, requiring a witness for refusal may not reflect standard practice and could impose an unnecessary barrier to exercising one's rights. Compulsion to comply with medical advice undermines the patient's autonomy, and stating outright that patients cannot refuse treatment, regardless of their decision-making capacity, contradicts established ethical and legal guidelines. Thus, respecting a competent patient's right to refuse treatment is essential in health care.
