Patients should also include advance health care directives. These three medical orders (DNR, MOST, POLST) must be signed by a physician and are the most frequently used medical directives. The DNR (Do Not Resuscitate order) expresses the patient's preference to decline Cardio-Pulmonary-Resuscitation (CPR). The names of the other more comprehensive physician orders (MOST form or POLST form) will vary by your state. In some states - it is called a MOST order form (Medical Order for Scope of Treatment) and in other states this document is called a POLST order form (Physician Order for Life Sustaining Treatment). These medical treatment preference documents are critical - especially for the elderly for whom resuscitation by emergency responders (EMTs) may cause painful and/or life-threatening injuries. Without these documents to guide the emergency responder - patients must understand that EMTs are trained to automatically administer a full range of emergency life saving measures. For many patients such measures may be a wonderful blessing; for others who are elderly or frail or in very poor health - these same measures may be a curse. The patient who wishes to decline automatic EMT measures - should be aware that most jurisdictions will require that the DNR, the MOST, and the POLST documents included in the Vial of Life container be original versions including the physician's signature.
