A Do Not Resuscitate (DNR) order is a specific medical instruction written by a physician that directs healthcare providers not to perform cardiopulmonary resuscitation (CPR) if a person’s heart or breathing stops. This order is a planned decision made in advance, falling under the umbrella of advance care planning, which allows individuals to specify the medical treatment they wish to receive should they become unable to communicate their wishes. The DNR order is a choice to refuse a particular intervention, ensuring a person’s preferences are honored during a life-threatening event. This decision reflects a careful consideration of a person’s current health status, prognosis, and personal priorities for the end of life.
Understanding the Intervention Being Declined
The intervention declined by a DNR order is cardiopulmonary resuscitation (CPR), a complex, multi-faceted procedure intended to manually restore heart and lung function. CPR typically involves aggressive chest compressions to circulate blood, artificial ventilation, and the use of a defibrillator to deliver an electrical shock to the heart. Emergency cardiac drugs, such as epinephrine, are also administered intravenously.
The success of these interventions can be quite low, particularly for patients with severe underlying chronic conditions or advanced age. For individuals with serious illnesses, the rate of survival to hospital discharge after in-hospital CPR is often reported to be low, sometimes less than 20% overall, with much lower rates for those who are frail or have metastatic cancer. Even when initially successful, resuscitation can lead to complications, including fractured ribs, internal injuries, and severe neurological impairment due to periods of oxygen deprivation. The decision to forgo CPR is often made with the understanding that the procedure may not successfully restore a quality of life acceptable to the patient.
Primary Motivations for Choosing a DNR
The primary reason people choose a DNR order is to prioritize the quality of their remaining life over its potential quantity. Avoiding a prolonged dying process is a central motivation, as they wish to prevent their life from being sustained solely by invasive machines and technology. They may fear a scenario where successful resuscitation leaves them dependent on mechanical ventilation or with a severely diminished cognitive and functional status.
This decision frequently occurs in the context of terminal illness or irreversible disease, where medical recovery is no longer a realistic outcome. When a patient has an advanced condition like end-stage heart failure or widespread cancer, resuscitation is generally understood to be futile, only serving to briefly delay an inevitable death while adding suffering. In these situations, a DNR order ensures that the focus of care remains on comfort, pain management, and maximizing the person’s dignity in their final days.
Advanced age and frailty also significantly influence the decision, as CPR is statistically less likely to succeed in the elderly population and more likely to cause harm. For people aged 70 and over who receive CPR, the survival rate to discharge is often less than 5%. Knowing this poor prognosis, many older adults choose to accept the natural course of their life rather than endure a painful procedure with minimal chance of a meaningful recovery.
The choice to obtain a DNR order is an exercise in respecting patient autonomy, which is the right of an individual to refuse unwanted medical treatment. Competent adults have the right to make decisions about their own body and care, and a DNR order legally affirms their preference to decline aggressive, life-sustaining measures. This personal choice is guided by their individual values, beliefs, and definition of a good life.
Addressing Common Misconceptions About DNR Orders
A frequent and concerning misconception is the idea that a DNR order means “Do Not Treat,” which is fundamentally untrue. A DNR order is narrowly focused, applying only to the event of cardiac or respiratory arrest. Patients with a DNR order still receive full medical treatment for all their underlying conditions, including medications, surgery, and management of symptoms.
The order simply instructs healthcare staff to withhold CPR, not to withdraw all care. A patient can still receive antibiotics for an infection, treatment for a broken bone, or any other intervention aimed at improving their overall health and comfort. Clinicians must maintain a distinction between the DNR status and the patient’s comprehensive treatment plan.
Another misunderstanding is that a DNR order is equivalent to an order for “Comfort Care Only” or that it mandates hospice enrollment. While many patients with DNR orders choose palliative or hospice care, the DNR itself is a separate medical order. Comfort Care Only is a broader philosophy that proactively limits all aggressive medical interventions, whereas a DNR only limits resuscitation efforts. The presence of a DNR does not preclude a person from receiving aggressive treatments for potentially reversible conditions.
The Process of Documentation and Implementation
The implementation of a DNR order begins with a thorough discussion between the individual and their physician about the patient’s condition, prognosis, and the potential outcomes of CPR. This conversation is essential for the decision to be truly informed, ensuring the patient understands the medical realities of the intervention they are declining. The physician then writes the DNR instruction into the patient’s medical record, giving it the authority of a medical order.
The documentation often involves formal legal forms, such as an Advance Directive or a Living Will, which outline broader end-of-life wishes. In many states, a specific portable medical order form like POLST (Physician Orders for Life-Sustaining Treatment) or MOLST is used, which is a standardized, brightly colored document signed by a physician. These specific forms are designed to travel with the patient and are legally recognized by emergency medical services (EMS) personnel outside of a hospital setting.
If a person lacks the mental capacity to make the decision, a legally designated surrogate decision-maker, often named in a Durable Power of Attorney for Health Care, steps in. This surrogate must base their decision on the patient’s known wishes or, if those are unknown, on the patient’s best interests. Communicating the DNR status across different care settings is a logistical necessity to ensure the person’s wishes are consistently honored by all providers.
