For more information on which states are currently using POLST, see this website hosted by the Oregon Health & Science University. Here is their description of POLST:
The Physician Orders for Life-Sustaining Treatment (POLST) Paradigm program is designed to improve the quality of care people receive at the end of life. It is based on effective communication of patient wishes, documentation of medical orders on a brightly colored form and a promise by health care professionals to honor these wishes.
