“Moribund Obesity”: Palliative care diagnosis or poorly chosen label?


I’ve always had a fascination with how certain phrases influence practice and how established terms frame and reinforce provider attitudes toward the individuals they care for. I recently began exploring the experience of nursing home life among obese residents, and in a literature search came across Deepak Gupta’s letter the editor “Moribund Obesity as a Palliative Care Diagnosis.” Now, add to my list of questionable palliative care related diagnoses (presently including: psychogenic mortality, failure to thrive, organic brain disease, et al.) the newly coined “moribund obesity.” At the risk of oversimplifying, a morbidly obese individual achieves moribund status when usual interventions to reduce or control obesity fail as a result of some insurmountable barrier or collection of barriers—physical, psychological, social or spiritual. Most distressing in the article, suggested spiritual barriers include “inadequate self-control and the spiritual pain that comes from feeling worthless or abandoned by God.” I don’t know why, but I bristled when I read this. Perhaps it’s my reading a “blame the victim” subtext into this, or perhaps it’s that this seems to downplay the complexity of overeating, and emerging science suggesting neuro-physiological processes that may parallel addiction.

The adjective “moribund” runs the risk of becoming a “line in the sand”, defining when palliative care becomes appropriate. In the most extreme scenario the “moribund obese” label becomes the green-light for palliative intervention and discontinuation of other therapies. In addition, we risk overlooking the need for palliative intervention periodically or continuously across the course of a refractory chronic condition. In the case of obesity, this may be long before the morbidly obese individual satisfies criteria to earn the “moribund obese” label.

In all fairness, the tenor of Gupta’s commentary suggests a call to recognize the complexity of chronic refractory obesity and the need for palliative intervention. The reality is that most of our knowledge about the palliative care needs in morbidly obese individuals is based on anecdote. There are few studies that have documented the range of their palliative care needs or provided direction for comprehensive intervention. Complex, long standing, multifactorial conditions with poorly understood etiologies are often the most challenging to manage. They are often characterized by good days and bad days, by periods of remission and exacerbation—some explained, some not. We often attempt to capture these conditions using imprecise terms (e.g. failure to thrive) which may satisfy the need to diagnose but often result in suspending additional assessments vital to an effective palliative care plan. I am not sure that inventing a new term (moribund obesity) that attempts to capture when someone has crossed an ill defined line on the way to mortality is helpful. In the end such classification may have the undesired effect of relegating a sub-population of complex, chronically obese individuals to a palliative “island of misfit toys.” Perhaps a better tack is to banish “moribund obesity” to the “island of misfit terms.”

I am confused as to Dr. Gupta's reasoning in coining this new term, "moribund obesity." Obesity is a risk factor for many other problems and conditions, and therefore cannot in itself be a palliative care diagnosis. Even the author's own example of pulmonary embolism being directly due to obesity is false. Obesity increases the *risk* of PE, just like it increases the risk of OSA, or diabetes. The author's own anecdote, of an obese man with chronic recurring cellulitis could just as easily be about an average-sized man with the same medical problems with chronic cellulitis.

I think the article misses the point. How can obesity be a palliative care diagnosis when it is not even a diagnosis that causes any problems in and of itself? It's like calling "old age" a palliative care diagnosis.

Moribund - from Marion Webster's Dictionary:
1: being in the state of dying : approaching death
2: being in a state of inactivity or obsolescence
Ok, so perhaps both apply to some obese patients. The major issue I have with this term is the emphasis on lack of curative options as a criteria for palliative care. This is the model of palliative care, tied to hospice and it's requirements of a limited prognosis. The other issue I have is with the term "palliative care diagnosis." What is that? Is pancreatic cancer a palliative care diagnosis? Certainly, it is an illness where palliative concerns predominate, but I'm not sure what the author meant by palliative care diagnosis. I think he is trying to define "palliative diagnoses" as conditions for which curative treatment options are no longer available...again raising my concern addressed above. Palliative care can and in many cases should be delivered in conjunction with life-prolonging care, not defined in opposition to it.

Alex, your points are right on!

This article makes me think about a hospice case that still haunts me. The case was a 31 yo anorexic woman who had been fired from all the treatment programs in Denver ('manipulative' blah, blah, blah). When I saw her in hospice, she was begging for a bisacodyl PR. On one hand, I wanted to respect her wishes, on the other, I didn't want to support this dreadful disease. I remember thinking helplessly to myself 'all you have to do is eat.' but it is much more complicated than that. She died, peacefully, at the age or 31, from a completely reversible process. As society continues to expand at the waist, we will likely be faced with cases of obesity where similar feelings arise. 'All you have to do is lose weight.'

Caring, and the Family Caregivers We Don’t See

Over lunch at a restaurant in Manhattan, my father and I talked about long-term care insurance and the emergence of senior centers and nursing homes across the U.S. that offer a variety of ethnic cuisines and cultural events, catering not only to a growing population of adults over 65, but also, to an increasingly diverse population of adults who call the U.S. their home. This conversation was different from many similar ones before it – we weren’t talking about my research; we were talking about our own lives.
My parents immigrated to the U.S. in the late ‘70s and early ‘80s, following their parents’ advice on professional opportunities that seemed unimaginable in India at the time. Although they considered moving back soon after to care for their aging parents and to raise children, they ultimately decided to stay in the U.S. As I chronicled earlier, my paternal grandparents lived with us until I completed middle school, at which point they returned to India and lived with my mater…

Practical Advice for the End of Life: A Podcast with BJ Miller

This week we talk with BJ Miller, hospice and palliative care physician, public speaker, and now author with Shoshana Berger of the book "A Beginner's Guide to the End."

As we note on the podcast, BJ is about as close as we get to a celebrity in Hospice and Palliative Care.  His TED Talk "What Really Matters at the End of Life" has been viewed more than 9 million times.  As we discuss on the Podcast, this has changed BJ's life, and he spends most of his working time engaged in public speaking, being the public "face" of the hospice and palliative care movement.

The book he and Berger wrote is filled to the brim with practical advice.  I mean, nuts and bolts practical advice.  Things like:
How to clean out not only your emotional house but your physical house (turns out there are services for that!)Posting about your illness on social media (should you post to Facebook)What is the difference between a funeral home and mortuaryCan I afford to die?  …

Top 25 Studies in Hospice and Palliative Care (#HPMtop25)

by: Kara Bishoff (@kara_bischoff )

Back in 2015 we wrote a post asking for input on what articles should belong on a list of the top 25 articles in hospice and palliative care.   We decided to focus on hospice palliative care studies and trials - as opposed to review articles, consensus statements and opinion pieces.

Here’s what we came up with. It was hard to pick just 25! We highly prioritized clinical utility and tried to achieve diversity & balance. Many others are worthy of inclusion. Take a look and let us know if you have suggested changes for next year.
