ME/CFS: Researchers question credibility of NICE guidance

Guidance from the National Institute for Health and Care Excellence (NICE) on myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) “deviated from usual scientific standards” and could cause harm, a group of researchers have claimed.

More than 50 international specialists analysed NICE’s 2021 guidance and questioned the evidence underlying the decision to stop recommending graded exercise therapy (GET) and recommending only cognitive behavioural therapy (CBT) for symptom management and distress.1 “The consequences of this are that patients may be denied helpful treatments and therefore risk persistent ill health and disability,” they wrote in the Journal of Neurology, Neurosurgery and Psychiatry.

NICE has vehemently rejected the study’s conclusions, telling The BMJ that it stands by the recommendations outlined in the guidelines.

The institute produced its first CFS/ME guidance in 2007, which recommended two forms of rehabilitation—GET and CBT. It then reviewed the guidelines in 2021 and said that some people with ME/CFS reported “worsening of symptoms with GET and no benefit from CBT.” It said that, while research on pacing (energy management) was “sparse,” this method was “preferred by many people with ME/CFS.” As such, NICE recommended pacing instead, which involves patients managing their activities to stay within their energy limit.

The BMJ previously reported that four members of the NICE committee developing the recommendations had left the group just weeks before the final guideline was due to be published, prompting suggestions of disagreements over the content.2 The committee had 21 members, including five lay members rather than the usual two, plus another co-opted member representing the ME Association.

Different evidence prioritised
In their paper the researchers said that NICE had “prioritised evidence from qualitative studies and patient organised surveys” in its 2021 review and that it had included “remarkably little aggregation and meta-analysis, making it hard to conclude what treatments worked.” They added that the committee had “created a new definition of CFS/ME, which ‘downgraded’ the certainty of trial evidence.”

The researchers highlighted a number of meta-analyses published since 2007, which they argued showed that the evidence for GET and CBT had strengthened, not weakened, since the initial NICE guidance. They pointed to NICE guidance on other relevant conditions, including chronic unexplained pain, that still recommended GET and CBT. Their paper asked, “Since such pain is common in CFS/ME, how can a clinician choose which guideline to follow?”

On the pacing recommendation, the researchers added that the “only substantial trial” on this showed that it was “no more effective” than specialist medical care alone and “less effective than either CBT or GET.” As such, they warned that the guidance could result in patients missing out on helpful treatments.

Trudie Chalder, coauthor and professor of cognitive behavioural psychotherapy at the Institute of Psychiatry, Psychology & Neuroscience at King’s College, London, said, “In this analysis we have systematically assessed this NICE guideline for CFS and ME and found it to be inconsistent in its process of review and its consideration of evidence . . .We are concerned about the healthcare implications of the revised 2021 guideline: clinicians will not be able to offer GET.”

NICE rejects findings
In response, a spokesperson for NICE said, “We reject entirely the conclusions drawn by the authors of this analysis, and in particular their conclusion that NICE has not followed international standards for guideline development which has led to guidance that could harm rather than help patients.

“In developing our guideline, as well as bringing together the best available scientific evidence, we also listened to the real, lived experience and testimony of people with ME/CFS to produce a balanced guideline which has their wellbeing at its heart.”

NICE has said that it will provide a “detailed response to this analysis” soon, but it was “confident that system partners and the ME/CFS community will continue to work together to make sure the important recommendations in our guideline are implemented.”
They make no mention that the whiners are the same people whose work has been rated as awful, which is completely unserious. This is extremely relevant, they have huge biases and conflicts of interest listed right below their commentary. And massively distort what happened. They make it seem as if all NICE did is look at some anecdotes and recommended a "treatment", which pacing isn't, based on nothing.

Yellow journalism, basically propaganda. In academia. Absurd. Completely absurd lack of integrity. This system is broken beyond repair.

Eight (or more) logical fallacies in that paper bemoaning the new NICE guideline for ME/CFS
Sealioning. Plenty has been written already. This is not sincere. Or at least it doesn't seem to be at all.

In reply to others' questions about the definition of GET.

Not sure about the exact wording, but could it be helpful to check the
videos accompanying the PACE trial report in The Lancet?

Only remember vaguely but maybe the principal investigators very clearly
stated there that patients need to be persuaded that they have to
increase there physical activity to get better no matter how they feel
-- because the evidence allegedly says that GET is utterly safe?

Here is the clip of Clare Gerada saying

"If you feel rotten I still want you to do that activity... Even if you feel absolutely exhausted. I still want you to do your 10 minute walk in the morning and a 10 minute walk in the evening... It will be safe, all of the evidence that we've put together and all the research literature shows it's absolutely safe. You will not do yourself any harm."

And Sharpe saying they are safe after the follow up paper.

 
And another article in Pulse Today by Emma Wilkinson: Row reignites on NICE ME/CFS guidance as researchers question process

There is one comment from a GP (I think) under this article:

"David Jarvis 13 July, 2023 3:07 pm
Any guideline with ME in the title is going straight in the bin anyway for lack of rigour in using a pseudoscience sounding made up name. With no proven, as yet, pathological process it is by definition a syndrome."

Is he right? Or are there other known diseases that would be in a similar boat regarding strength of pathological evidence/process?

I would be interested to hear your views.

I know a few GP's socially and I often see them wince when I use the word, 'disease'. I always assumed that they don't realise how many ME/CFS studies there now are.
OR, am I wrong to describe ME/CFS as a disease? Are we not there yet regarding strength of evidence?

It's strange that Lancet TV never took off...

He has a fair point. There are a lot of very dubious names for medical conditions that continue simply out of convenience. But myalgic encephalomyelitis is to an extent in a league of its own for being dubious. It implies that there is brain inflammation when we can be pretty sure there isn't in any normal sense of the term. If it were not for the fact that the alternative name, CFS, has been so much associated with bad medicine I would strongly recommend that ME is replaced by something more appropriate. So I very much sympathise, and technically I think the GP is quite right, but life is more complicated.

OR, am I wrong to describe ME/CFS as a disease? Are we not there yet regarding strength of evidence?

I don't think ME/CFS warrants being called a disease. The term 'a disease' (with the article a) normally implies a process known to be due to some common cause, even if the cause is not fully understood. Tuberculosis is a disease. Skin melanoma is probably a disease. Lung silicosis is a disease. Rheumatoid arthritis is probably not a disease but might be allowed to be. ME/CFS doesn't get near to qualifying yet. It is genuinely a syndrome, as the GP said. I don't think SEID is a very good term, for that reason.

I appreciate you taking the time to clarify this. Thank you.
 
I'm perfectly happy to accept that ME is the wrong name, and that it's a syndrome.

I would also bin the name CFS as it leads to so much misunderstanding both from our doctors and as an enabler for all the BPS research.

What I can't accept is doctors deciding that just because what we suffer from is stuck with inappropriate names, the guideline must be wrong and we don't deserve medical care.

Trial Description of GET incremental approach

Wearden 1998 “Exercise intensity was increased when there was a consistent recorded reduction
of 10 beats per minute in post-exercise heart rate for one week and two points on
the perceived exertion scale...”

Powell 2001 “A graded exercise programme was designed in collaboration with each patient
and tailored to his or her functional abilities.”

Moss-Morris
2005
“Exercise goals were set collaboratively between the researcher and participant.
Initial exercise intensity and duration were set at a level that had been identified
during exercise testing as achievable and unlikely to exacerbate symptoms in the
patient.”

Wearden 2010 “The manual was reviewed, patient priorities were determined, and goals for
rehabilitation set collaboratively by the patient and therapist. Care was taken to set
goals at a level easily manageable by the patient.”

Wallman 2004 “Subjects were instructed to exercise every second day, unless they had a relapse.
If this occurred, or if symptoms became worse, the next exercise session was
shortened or cancelled. Subsequent exercise sessions were reduced to a length
that the subject felt was manageable.”

Jason 2007 “The aim was for behavioral homework to reinforce gradual, consistent increases in
selected physical activity and discourage rapid fluctuations in activity. Preliminary
targets were set at a safe, achievable level to maximize the likelihood of success. …
As an example of stretching and strengthening, the participant would start with
one set of four repetitions for each exercise. If the patient was successful with this
assignment and felt no physical repercussions or delayed recovery response, they
would then be encouraged to gradually progress until there was one set of eight

Couldn’t agree more. From his comments David Jarvis sounds like the sort of doctor that try to ensure I never see a second time if I ever have the misfortune of encountering them.

In response to the question above there is an S4ME thread called Can we call ME/CFS a disease?

It’s should be fairly self-evident that a document which just had ME in the title would have even more doctors reacting like this. Some “ME only” advocates either don’t seem to recognise this or at least don’t mention it when discussing the pros and cons of using ME/CFS vs ME in educational material for doctors.

Put another way, I don’t use ME/CFS because I like the name CFS.

Wow. This is a really good read. Thanks Robert.

Although the thread does not come to a firm conclusion, I do feel better informed having read it :-)
