When I was a third year medical student rotating for the first time on a general medicine service inpatient ward, my team admitted a 30 year-old woman in acute congestive heart failure. That a 30 year old was in congestive heart failure was unusual enough. Even more shocking was the cause: an echocardiogram revealed a tumor sitting on top of her mitral valve preventing the normal flow of blood out of her lungs to the left side of her heart. No one on my team, including the attending physician, had ever seen anything like it. A CT scan revealed widely metastatic cancer throughout her entire body—it looked as if every square inch of her had been splattered with buckshot—with no obvious dominant lesion to suggest its point of origin. With the diagnosis "metastatic cancer of unknown primary," her prognosis was grim. Our patient's oxygen saturation was hovering near 75% (normal being above 95%) despite the 15 liters/minute of oxygen we had flowing through her face mask. She was too weak to rise unassisted from the bed. As we watched her lying there, laboring to breathe, we all realized we were watching someone in the process of actively dying.
When our attending gently explained to her there was nothing we could do to save her, she paused, mustered up the energy to give a small shrug, and from behind her oxygen mask said something in a tone I will never forget for its nonchalance: "I guess that's just the way it goes..."
The way she seemed to accept her fate, the courage she displayed in the face of it (if that's indeed what we were seeing), was made all the more poignant when we learned she was a single mother of four small children.
THE CONUNDRUM OF END OF LIFE CARE
My patient's case was as unusual as it was tragic: 30 year olds rarely get cancer and those who do rarely present to hospitals only 24 hours before they die. She had no real time to prepare herself or her family, and had no real decisions to make. But in the 21st century, many of us will face a different experience. We'll see our deaths coming, be surrounded by caregivers attempting to prevent or forestall it, and in the technology-rich environment of the modern hospital, innumerable decisions will confront us and the medical teams in charge of our care.
One question typically dominates all end-of-life experiences. It's the first question that must be answered before any other, and answered again and again as circumstances change: what is the goal of care? Is it to cure (and palliate) or to palliate only? How we answer this question hinges on the likelihood that cure is possible and the recognition of it, or lack thereof, on the part of the medical team, patient, and the patient's family.
This is often far harder a question to answer than most people think. Identifying the point at which a patient shifts from having a chance to survive a disease to actively dying is frequently difficult to nail down. Even patients with incurable illnesses like terminal cancer can often live months or even years beyond what doctors predict. Yet predicting likely outcomes is exactly what doctors struggle to do every single day with critically ill patients in order to be guided in choosing appropriate therapies.
At what point, then, should doctors, patients, and patients' families step back, look at the proverbial forest for the trees, and recognize though we might reverse the kidney failure, treat the pneumonia, and anti-coagulate the pulmonary embolism, the likelihood of survival has slipped below our threshold for continuing to provide treatment aimed at cure? The difficulty in answer this question is compounded by the fact that statistical probabilities for survival on which doctors rely predict outcomes for populations better than for individuals. Exactly where a particular patient will fall on the survival curve for a given diagnosis like, for example, lung cancer (to the far left where survival is measured in hours or to the far right where survival is measured in months or even years—or somewhere in the middle where, by definition, most patients land) is largely unknowable. Studies have shown repeatedly that, for all our population statistics, doctors are uniformly poor at predicting when the particular patient in front of them will die. Yet when the spread between the shortest survival times and longest isn't days or weeks but rather months or years, knowing where a particular patient is likely to fall really does matter. If he or she is highly likely only to live a few hours no matter what we do, aggressive measures would be considered by most to be inappropriate. If, on the other hand, he or she is most likely to live months or even years with whatever underlying diagnosis he or she has, the opposite is true. What's more, the likelihood of survival constantly changes as new complications develop or resolve. Physicians must constantly recalculate the odds and often change strategies from cure to palliation (and even sometimes back again) depending on how a patient's course proceeds. It's an enormously challenging process.
The key thing to know as a patient facing a potentially (or known) terminal illness is this: no one can predict when you will succumb. Where on the survival curve you'll find yourself is anybody's guess. When to shift from an intent to cure to and attempt to palliate must always be individualized. Unless you're in the medical field yourself and have watched others die, you don't know what to expect as you go through your own experience, so it's difficult to know when you're entering waters that will ultimately prove intolerable for you. The best advice I have to give for people trying to decide about when to shift strategies is:
- Know yourself. How important is a pain-free (or minimally painful) existence to you? How much pain can you tolerate on a chronic basis before life is no longer worth living? What self-management skills are most important to you (being able to feed yourself? Dress yourself? Clean yourself up after you go to the bathroom?). You often won't know the answers to these questions until you experience the circumstances that cause you to ask them. But consciously asking and answering them can be empowering.
- Communicate. With your family. With your physician. With your nurses. Talk in general terms about your preferences surrounding dramatic life-saving measures (CPR, defibrillation, artificial ventilation) before you ever come close to needing them. Do this even before you're even diagnosed with anything that might make such conversations necessary. If you change your mind (and you always can) revisit the subjects as many times as necessary, no matter how awkward it may be for you or your family.
WHO DECIDES WHEN TO PALLIATE?
The answer, at first glance, might seem as if it should be doctors and patients and patient's families all working together. And this is usually, in my experience, how it goes. But making a collaborative decision to switch from an intent to cure to an intent to palliate only, or leaving the decision entirely in the hands of a patient's family when the patient is unconscious or otherwise unable to decide for themselves often has an unintended consequence: guilt. Family members who find themselves burdened with decision-making authority over their ill loved one who decide to withdraw aggressive medical care even for the most logical and compassionate of reasons are often left feeling, whether rational or not, that they themselves killed the very person they meant to protect.
Having seen this multiple times early in my career, I've since taken to telling families when further attempts to cure seem hopelessly futile that, though their agreement is necessary to switch to palliative care only, I'm more informing them that's what we should do than asking their permission. It may seem at first glance overly paternalistic to say, "This isn't your decision to make, and it's not mine, either. The disease made the choice for us all." But in all the years I've been caring for terminally ill patients, the only reaction I've ever encountered in response to my saying this, usually after days or even weeks of emotional ups and downs as their loved one improved then worsened then improved and then worsened again, is relief.
WHERE TO DIE?
