No. The MOST is a medical order set, not an advance directive. The treatment types and choices on a MOST are only a few of the possible issues that advance directives can address. If a person has advance directives in place (living will, MDPOA, etc.), the person completing the MOST with the patient/resident should review the advance directives so that the MOST orders match the advance directives—or the advance directives should be revised or revoked to match current choices documented on the MOST. If a person completing a MOST does not have any advance directives, the MOST covers the key life-sustaining treatment choices, and there is room to add additional orders. However, the MOST cannot be used to appoint a healthcare agent, nor does it address personal care or non-medical matters. The MOST may function as a CPR directive for any person who has a MOST, but standalone CPR directives are still valid. Until all EMS services and ED/ERs are familiar with the MOST, it’s a good idea for a patient/resident to have both. Some long-term care facility policies require a facility-specific CPR directive form. There is no problem with using those forms along with a MOST as long as the instructions do not conflict.
