My patient and a Hemingway protagonist
Whether by coincidence or irony, I started reading Ernest Hemingway’s short story “The Snows of Kilimanjaro” the same day that I met Mr. Barry. He reminded me of the story’s protagonist, Harry, lying on the cot with a gangrenous leg, waiting to die. Harry could sense death approaching. He reminisced about his past. All he wanted was to drink his “whiskey-soda.” “Darling, don’t drink that. We have to do everything we can,” his wife said. “You do it. I am tired,” Harry said, and continued to drink his whiskey-soda.
Mr. Barry looked tired. Tired of life? I can’t say with certainty. However, if I had to guess, the medical team’s heroics meant nothing to him. Unfortunately, he was not awake like Harry and could not do what he wished. I wondered what snippets of his life flashed before him as he lay on his bed at home for days. Did he want to have a whiskey-soda before dying? But we are not letting him die. Not easily anyway. We have to do everything we can: medications, coronary angiogram, dialysis, multiple rounds of CPR. Why?
In this country, we need permission to forgo CPR. If there are no advanced directives or next of kin available to discuss end-of-life care, performing CPR is the default status for all hospitalized patients, irrespective of the underlying severity of the illness. A unilateral DNR order written by a physician in good conscience (in a medically futile situation), but to which the patient has not consented, is generally invalid in most U.S. states. If health directives are not available, CPR will be administered on the presumption that the patient would want us to “do everything we can.” The medicolegal consequences and fear of not administering CPR is more profound than being found wrong and defying a patient’s wishes against CPR.
In patients with outside-hospital cardiac arrest, especially if related to ventricular fibrillation, early bystander CPR improves the survival rate. Hence, it makes sense for first responders and paramedics to administer CPR as the default option, focusing on the technique, rather than thinking about its utility based on the patient’s underlying comorbidities.
In the inpatient setting, however, physicians have enough information to comprehensively evaluate the patient. In a cohort of 5,690 critically ill ICU patients, obtained from a U.S. registry, the rate of survival to discharge after inpatient cardiac arrest is very low at 12.5%. Chronic health conditions, malignancy, end-stage renal disease, multiorgan dysfunction, need for vasopressor support, prior CPR, initial rhythm of asystole, or PEA advanced age were all associated with a less than 10% survival rate after CPR.
Dying is a process. Administering CPR to a dying patient is of little to no value. For Mr. Barry, it resulted in a bruised chest and broken ribs. James R. Jude, MD, one of the pioneers of closed chest compression, or modern-day CPR, wrote in 1965 that “resuscitation of the dying patient with irreparable damage to lungs, heart, kidneys, brain or any other vital system of the body has no medical, ethical, or moral justification. The techniques described in this monograph were designed to resuscitate the victim of acute insult, whether be it from drowning, electrical shock, untoward effect of drugs, anesthetic accident, heart block, acute myocardial infarction, or surgery.”
Yet, doctors continue to provide futile treatments at end of life for a variety of reasons: concerns about medico-legal risks, discomfort or inexperience with death and dying, uncertainty in prognostication, family requests, and organizational barriers such as lack of palliative services that can help lead end-of-life care discussions. Despite knowing that CPR has little benefit in critically ill patients with terminal illness and multiorgan dysfunction, we often ask the patient and their surrogate decision-makers: “If your heart stops, do you want us to restore your heart by pressing on the chest and giving electric shocks?” The very act of asking the question implies that CPR may be beneficial. We often do not go over the risks or offer an opinion on whether CPR should be performed. We take a neutral stance.
Anoxic brain injury, pain from broken ribs, and low likelihood of survival to discharge with acceptable neurologic recovery are rarely discussed in detail. Laypeople may overestimate the chances of survival after CPR and they may not comprehend that it does not reverse the dying process in patients with a terminal illness. When you ask about CPR, most families hear: “Do you want your loved one to live?” and the answer is nearly always “Yes.” We then administer CPR, thinking that we are respecting the patient’s autonomy in the medical decision-making process. However, in end-of-life care, elderly patients or surrogates may not fully understand the complexities involved or the outcomes of CPR. So, are we truly respecting their autonomy?
