Most of us in North America live in cultures that almost never talk about death and dying. And medical progress has led the way to a shift in the culture of dying, in which death has been medicalized. While most people wish to die at home, every decade has seen an increase in the proportion of deaths that occur in hospital. Death is often seen as a failure to keep people alive rather than a natural dignified end to life. This is at odds with what a lot of people actually want at the end of their lives: 70% of hospitalized Canadian elderly say they prefer comfort measures as apposed to life-prolonging treatment, yet as many as ⅔ of these patients are admitted to ICUs.

Discussing End of Life Care in Emergency Medicine
Find a quiet room to have end of life discussions. In an unresponsive patient, find a room where the patient cannot hear the discussion. It is prudent to assume the unconscious patient hears everything (1).
Allow patients and/or their families the time to tell their story so you can understand it. Avoid power struggles with families. It is often prudent to provide your clear medical opinion, and when appropriate, make clear recommendations rather than giving options only and leaving end of life decisions to family alone. This may help reduce the burden of this difficult decision on the family.
See Episodes 49 and 51 on effective patient communication and managing difficult patients.
Palliative Care Myth #1: Code status discussion should focus on descriptions of CPR/CCR
In discussions regarding goals of care and code status, talking about the risk of broken ribs will not help you, the patient and their family get any closer to effective decisions about goals of care. Rather, discussions around goals of care should include information regarding overall prognosis, patient goals, and explanations of different levels of care.
An informed decision involves sharing realistic expectations. The common and uncommon material risks of CPR/CCR and treatment (2) may include:
Uncomfortable investigations and treatments
Do Not Resuscitate (DNR) Orders in End of Life Care in Emergency Medicine
Palliative Care Myth #2: DNR means do not treat
DNR means no resuscitation in the setting of a full cardiopulmonary arrest. This is often misinterpreted, and sometimes associated with lower quality or less care. Patients can and should still receive full and aggressive medical management even if they are rendered DNR.
There is a movement, as stated in the AHA Cardiopulmonary Resuscitation Guidelines in 2010, towards changing the DNR order to ‘Allow Natural Death’ (AND). AND uses positive language, stating what we will do, as opposed to what we will not do. Patients and their families may feel less guilt and may be more likely to be agreeable to an AND order than to a DNR order.
Discussing Prognosis in End of Life Care in Emergency Medicine
There are multiple barriers to communicating prognosis which include:
Physicians in general are poor prognosticators: ED physicians in particular do not have experience taking care of patients over time in their trajectory towards death
There is uncertainty in medicine: uncertainty should be communicated with patients, this also leads to the patient’s increase in sense of trust with the health care team
ED physicians often feel a lack of ownership/responsibility regarding end of life discussions, as it is thought to be the responsibility of the primary care physician
Lack of skill in communication of prognosis
We assume patients do not want to know their prognosis; however, it has been shown that the majority of patients do want to know their prognosis.
Palliative Care Myth #3: It is the primary care physician’s role to discuss end of life issues
End of life discussions and issues around prognosis and palliative care are appropriate in the ED, and often lead to more appropriate care pathways from the ED.
Models for Prognostication in End of Life Care
There are two models of death, which can help ED physicians prognosticate for patients. The first one describes the final hours-days and the second one describes the final months-years.
The ‘Two Roads to Death’ Model (Fig 1):
Usual Road: In this pathway, patients are sleepy, lethargic, obtunded and then progress towards death. Death typically occurs quickly.
Difficult Road: In this pathway, patients are restless, confused, develop hallucinations, delirium, may develop seizures, and ultimately progress towards death. In this pathway, death is typically prolonged and more difficult.
Trajectory of Illness Model (Fig 2): This model allows one to prognosticate death based on illness diagnosis, and over a longer period of time. There are four different categories of dying.
Sudden Death: In this trajectory, patients have not been ill, and there is nothing to predict anything bad will happen. Patients suddenly become critically ill or injured and die. (i.e. sudden massive MI, traumatic injury, etc.)
Frailty: In this trajectory, patients die of ‘old age’, and have a slow and gradual decline. These patients may or may not develop a severe illness, but slowly decline in mobility, function and/or cognition, and ultimately die from a complication of their progressive disability.
Terminal Illness: In this trajectory, it is expected that patients will have a prolonged illness where they can generally maintain their function, until the end of life, when function sharply drops off. (i.e. cancer)
Organ Failure: In this trajectory, there is a relatively steep decline in function with intermittent exacerbations. Patients ultimately die during one of these exacerbations, and if they survive, they never reach their prior level of function. (i.e. heart failure, COPD)
Prognostic Signs at the End of Life
Besides the obviously crashing patient, there are multiple signs on physical exam that can give us clues that a patient is near death. Some of these signs include:
Delirium with hypotension and tachycardia: median survival 10 days
Death rattle: medial survival 1 day
Respirations with mandibular movement: median survival 2.5 hours
Cyanosis to extremities: medial survival 1 hour
Palliative Care Myth #4: Making a patient palliative results in shortened survival
Early palliative care in multiple studies has been shown to prolong survival.
Approach to End of Life Communication
Introduce yourself, give information that you have reviewed
Ask ‘what is your understanding of your loved one’s illness, their quality of life?’
Ask ‘what were you hoping we can do for your loved one?’
Ask what patients/families are most afraid of
Ask ‘if your loved one were to die tomorrow, what would they want us to accomplish before that?’
Get into arguments
A useful mnemonic for end of life communication is the SILVER mnemonic:
Elicits information regarding baseline level of function, behaviours, and symptoms that suggest progressive decline
Elicits information regarding current diagnosis, prognosis, and treatment plan
Elicits information regarding key players in decision making, including family and health care workers
Elicits information regarding previous end of life discussions, including advance directives
Elicits information regarding the patient’s personality and approach to life
Elicits information regarding how the patient views death and dying
Provides information regarding the patient’s disease process, current condition, and treatment options
Explains how end of life decisions will impact further treatment
Solicits questions from family and offers continued support and availability for further information.
Obtain an analgesia history and convert narcotics into morphine daily dose (MDD). Use a calculator for the conversion (there are multiple online calculators available). When switching from oral to IV, reduce the IV dose by 25% as a starting point. Titrate medications frequently: consider a 50% increase every 15-30 minutes.
SQ route and butterfly needles are reasonable options
Ketamine is not routinely recommended at this time by our experts in the palliative patient for pain control as it may cause emergence reactions
Opioids decrease the sensation of being shortness of breath. They are used for dyspnea at much smaller doses than they are for pain control (e.g. 0.5 – 2mg morphine IV).
Palliative Care Myth #5: Opioids hasten death
Studies have shown that O2 and CO2 levels stay the same despite the decreased respiratory rate associated with opioids. Opioids in the palliative patient are appropriate and ethically permissible as long as the intent is symptoms relief.
Consider adjuvant therapies for dyspnea:
Oxygen – although studies have failed to show comfort-oriented benefit of supplemental oxygen in the dying patient, our experts recommend it as it often makes families more comfortable
Non-invasive Positive Pressure Ventilation (BiPAP or CPAP)
A fan blowing air in the patient’s face has been shown to improve the dying patient’s comfort
Re-position the patient
Suction the upper airway
Scopolamine patch (delayed onset)
1-2 drops of 1% atropine eye drops under the tongue
Terminal delirium at the end of life is fairly common and may include moaning, restlessness, and agitation. Terminal delirium is difficult for families to watch. It should be treated aggressively and early. Treatment options include:
Benzodiazepines: In adults, start with midazolam 1-4 mg IV, with frequent reassessments
Haloperidol: 0.5-2 mg IV, with frequent reassessments
