[Choices at the end of life: opinion and attitude of health staff in comparison with the general population].

In an increasingly aging population, patients increasingly require palliative end-of-life care, given the increase in chronic and advanced organ diseases. Therefore, advance planning of the care they receive is essential, allowing patients, based on their principles and experiences, to freely and autonomously decide their preferences. The advantages of implementing this process include respecting patient autonomy; strengthening the relationship between doctor and patient; alleviating the burden that may fall on the family in decision-making at the end of their lives; improving satisfaction with the care received; avoiding excessive or invasive treatments with dubious benefits, or hospitalizations against the patient's wishes.
