Physician Orders for Life-Sustaining Treatment

POLST (Physician Orders for Life-Sustaining Treatment) is an approach to improving end-of-life care in the United States, encouraging providers to speak with the severely ill and create specific medical orders to be honored by health care workers during a medical crisis. POLST began in Oregon in 1991 and currently exists in 46 states, British Columbia, and South Korea.
