On Cooks and Cookbooks: Failure of a Palliative Care Pathway



by: Alex Smith @AlexSmithMD

Wouldn’t it be great if we came up with a standardized approach to caring for hospitalized patients in the last two days of life? Think of it. Experts in hospice and palliative care could come to consensus on the best palliative care pathway for hospitalized patients nearing the end of life. Standardized assessment of distressing symptoms, the use of opioids, and other common medications used near the end of life. We could incentivize use of pathway, and improve care across the board. We should do it, right?

Well in the UK, they did it. It was widely adopted in the UK and throughout Europe. And now they’re retracting it.

The Liverpool Care Pathway was just that – an intervention designed to export the best of hospice and palliative medicine to non-palliative care clinicians caring for hospitalized patients in the UK.  And now the government is scrapping it.

How did this happen? First, two critical must reads for more details. Stories in the media and medical literature documented serious concerns about the quality of care for patients dying under the Liverpool Care Pathway. An investigating review panel found serious issues with the implementation and dissemination of the pathway. The full report of the review panel can be found using this link.

The second source is a fantastic essay by palliative care pioneers Andy Billings and Susan Block on take away lessons from the failure of the pathway, published in the Journal of Palliative Medicine. Some of their take home points:
  • Interventions should be evidence based. A recent Cochrane review concluded there was insufficient evidence for palliative care pathways for the dying.
  • Interventions should be simple. The Liverpool Pathway had over 50 steps; it’s hard to implement such a complex pathway effectively.
  • Interventions require sustained monitoring, support, and/or coaching. The early adopters are often “true believers” – later adopters not so much.
Here I will restrict my comments to two main take home issues.

First, the “cook” issue. Tim Quill and Amy Abernathy wrote a compelling argument  in NEJM for training all clinicians in basic primary care - everyone should be able to at least cook pasta.  As we expand our horizons to train hospitalists, emergency providers and primary care clinicians in primary palliative care, we have to do so with a deep respect for our profession. We have selected palliative care because we have a deep sense of commitment to care for patients with serious illness. Ken Covinsky has observed that palliative care providers approach their work with “missionary zeal.” We are the true believers.  We have all drunk the Kool-Aide. But the non-palliative care providers we train have not.

When I conducted focus groups with emergency medicine clinicians about incorporating palliative care into the emergency department, one physician said:
This is an overgeneralization, but I think that palliative care has a little bit of a negative connotation in the emergency department. If you think about people who go into emergency medicine, they want to sort of act and do, cure. When someone comes in and their status is DNR or comfort care, it is not necessarily seen as a priority or as a good thing. The first reaction is almost “Why are they here? Why are they bothering us? This is not an emergency.” “
As we train others, we have to be acutely attentive to the fact that those we train do not have the same internal incentives to provide outstanding palliative care for their patients. This is not to say that non-palliative care providers cannot do a great job of caring for patients with serious illness. Rather, it’s to say we need to work twice as hard and be twice as diligent in training others to do this work, monitoring their progress, and providing feedback.

Second, the “cookbook” issue. Those of us in palliative care have received some serious training. Palliative medicine physicians now must complete a one -year fellowship and pass board certification. Our specialty is not easily reducible to a formula. We attend to emotional, spiritual, and social concerns. We learn advanced communication techniques so we can walk with patients and caregivers through the tough, painful, sad experiences of serious illness that would send other clinicians running scared.  This is not easy "anyone with a cookbook can do it" care.

We need to respect our profession and the complex work we undertake. We cannot reduce it to a cookbook. For this reason, I’m generally not in favor of “end-of-life” order sets. I’d rather tailor each decision to the clinical situation at hand.

To be sure, many palliative care concepts can and should be taught to primary care clinicians, hospitalists, cardiologists, etc.  But we must do so with full awareness of the differences between our missions and the complexity of decision-making for patients with serious illness.

I’ll leave you with some painful experts from the Review Panel report on the Liverpool Care Pathway.  Clearly, the care pathway worked well in some settings, and poorly in others.  Overall though, what strikes me most about the Review Panel's findings is the lack of patient or family involvement in decision making:
The Liverpool Care Pathway has its own generic document, designed to replace the contemporaneous medical records written by the clinical staff. In some hospitals, training had been supplied for those tasked with filling in the forms. But the Review panel was told that this training can be as little as an hour-long lecture which it was considered acceptable to miss. It was also told that filling this form in could be delegated to the most junior doctor who was sometimes tasked with “completing it at 3 o’clock in the morning”.

Many people recounted that agreement not to attempt cardiopulmonary resuscitation had been taken by the clinical staff as a proxy for agreement to start the LCP, which is clearly unacceptable.

Evidence from relatives and carers strongly suggested that care of the dying elderly is of the greatest concern: the Review panel suspects that age discrimination is occurring, which is unlawful. Nor should old age be taken as a proxy for lack of mental capacity. Each patient lacking capacity, of whatever age, on the LCP or a similar approach, should be represented by an independent advocate.

The Review panel heard many instances of both good and bad decision-making. Repeatedly, they heard stories of relatives or carers visiting a patient, only to discover that without any forewarning there had been a dramatic change in treatment. There now appeared to be no clinical care or palliative care, and the patient appeared to be unnecessarily or excessively sedated. As if caught in the midst of a perfect storm, relatives and carers would discover that a previously sentient person was now semi-comatose. They were told that, following an overnight decision by a relatively junior clinician, this patient had been ‘placed on the pathway.’ One senior consultant who gave evidence to the Review panel related how a surgical professor was apt to conclude discussions in Multidisciplinary Team meetings about certain patients with ‘this patient is unfit for surgery, so Liverpool Care Pathway.’ This is entirely unacceptable.

There were many stories of relatives and carers being handed a leaflet with ‘Liverpool Care Pathway’ on the cover, without any explanation. A common theme among respondents was that they were simply not told that their loved one was dying; this clearly contributed to a failure to understand that the patient was dying, compounded their distress and subsequently their grief, after what they perceived to have been a sudden death.

 ‘It seemed to us that once he was placed on this plan there was no further review. It seemed that he had simply been written off.’

The LCP is indeed a voluminous document that is daunting to complete, especially all of the variance requirements. In other words if you do something different from what the pathway requires then you must complete a variance report. Thus the document itself insists on a cookbook approach.

As a minimum standard for care of the hospitalized dying patient, it serves as valuable contribution, but it borders on onerous and I suspect that contributed to it's doom. We have focused on the minimum standard aspect, for supportive of care of dying patients in our hospital, and have reduced the LCP essence to a two page document. The modified care pathway includes only 3 pages with 3 main sections and 14 subsections whereas the original “Liverpool Care Pathway” has 19 pages with 3 main sections and 44 subsections.

I won't bore you with the results of our clinical audit, but one unexpected outcome was less use of sedative medication and more psychospiritual support of patients/families enrolled on the pathway. We believe that when the patient is "made palliative" then the junior doctors were putting up morphine and midazolam infusions more often, because that's what they think you do when a patient is "made palliative". The bottom line really involves proper training, as you emphasize in the post above.But it could be that a short guideline can help that junior doctor at 3AM.

Thanks for your comment dspaci! I hope you publish your work and it is scaled up in a thoughtful manner - with close attention to implementation in low quality hospitals.

Felicity Jones @faejones tweeted about a counterpoint defending the Liverpool Care Pathway, blaming a media furor for taking down a good pathway used with poor judgement.

The Liverpool Care Pathway for the Dying: What Went Wrong?

Here's a quote:

The application of any guideline or integrated care pathway without good clinical judgement will result in poor clinical care. Guidelines are written to guide, not to dictate. We are concerned that the vacuum left by the abolition of the LCP makes a return to the ‘bad old days’ of poor or non-existent communication about dying a real possibility: we would argue that the response to poor use should be right use, not non-use.

Just a point of clarification. Our pathway is 2 pages, but a third page lists starting doses for symptom mgt of commonly encountered symptoms. We do hope to publish the results. Thx

You raise a salient point about low quality hospitals, or hospitals without palliative care expertise. Can such an advisory document raise the bar so to speak, in regard to clarification of goals and adequate supportive care for patients and families in the context of imminent death?

I think there is ample LCP evidence of improvement in documentation around treatment goals; limited benefit for symptom control; but definite improvement in staff understanding of the process and thereby, increased confidence, if not competence.

I agree with Alex's comment that right use, not non-use, should be the response.

I had (as an outsider) quite mixed feelings about LCP.

I think that there were trumped-up politically motivated attacks. These attacks largely came from folks I already didn't agree with. So likely some degree of knee-jerk dislike and an unfair tendency to question motives, perhaps.

But I also (to myself), also wondered whether this was a plausible pathway to be implemented by generalists. I believe that I'm a specialist, and that I possess skills that most generalists do not. (There are always caveats here. In HPM, the pioneers learned on their own, without fellowship training, and many of them clearly are quite good at what they do.) So if I think that there are things that really require a specialist, why do I think I can put it in an algorithm instead? The algorithm has to end up being very complicated. So complicated that it isn't really functional, and ends up being a mini-fellowship instead.

The Dangers of Fleet Enemas

The dangers of oral sodium phosphate preparations are fairly well known in the medical community. In 2006 the FDA issued it’s first warning that patients taking oral sodium phosphate preparations are at risk for potential for acute kidney injury. Two years later, over-the-counter preparations of these drugs were voluntarily withdrawn by the manufacturers.  Those agents still available by prescription were given black box warnings mainly due to acute phosphate nephropathy that can result in renal failure, especially in older adults. Despite all this talk of oral preparations, little was mentioned about a sodium phosphate preparation that is still available over-the-counter – the Fleet enema.

Why Oral Sodium Phosphate Preparations Are Dangerous 

Before we go into the risks of Fleet enemas, lets spend just a couple sentences on why oral sodium phosphate preparations carry significant risks. First, oral sodium phosphate preparations can cause significant fluid shifts within the colon …

Dying without Dialysis

There is a terrific article in this weeks Journal of Pain and Symptom Management by Fliss Murtagh of King's College in London about the epidemiology of symptoms for patients with advanced renal failure who die without dialysis.  This study is important because while we know that patients with advanced renal failure have a limited life expectancy and the average age of initiation of hemodialysis is increasing, we know little about the alternatives to hemodialysis.  Specifically, we know nothing about symptoms affecting quality of life among patients who elect not to start dialysis (so called "conservative management" - is this the best label?).  This article provides a terrific counterpoint to the article in last years NEJM showing that nursing home residents who initiated hemodialysis tended to die and decline in function (see GeriPal write up here). 

The study authors followed patients with the most advanced form of chronic kidney disease (the new name for renal failu…

Survival from severe sepsis: The infection is cured but all is not well

Severe sepsis is a syndrome marked by a severe infection that results in the failure of at least one major organ system: For example, pneumonia complicated by kidney failure. It is the most common non-cardiac cause of critical illness and is associated with a high mortality rate.

But what happens to those who survive their hospitalization for severe sepsis? An important study published in JAMA from Iwashyna and colleagues provides answers and tells us all is not well. When the patient leaves the hospital, the infection may be cured, but the patient and family will need to contend with a host of major new functional and cognitive deficits.

Iwashyna examined disability and cognitive outcomes among 516 survivors of severe sepsis. These subjects were Medicare enrollees who were participants in the Health and Retirement Study. The average age of patients was 77 years.

When interviewed after discharge, most survivors were left with major new deficits in their ability to live independently. …
