Physicians orders for life sustaining treatment (POLST)
Is a document that states a person’s end-of-life wishes.
It is much more than an advance care directive which generally contains information about a person’s desire to be mechanically ventilated or artificially fed, and his desire for comfort care. This may include a "Do Not Resuscitate (DNR)" order, instructions about artificial nutrition, antibiotics and other medical interventions.
While an advance care directive is usually meant for a hospital, POLST is designed to instruct emergency personnel on what actions to take while the patient is still at home.
