Action for ME: The PACE trial and behavioural treatments for M.E. [position statement]

Yes, a major advance. But

BACME said:
In its guidance on therapy and symptom management, the British Association for CFS/M.E. does not refer to APT and/or pacing. Instead, it offers “pragmatic recommendations from experienced clinicians to guide practice when seeing adults with CFS/M.E., where specialist CFS/M.E. CBT and GET therapists are not available/appropriate […] Evidence-based therapies emphasize a therapeutic relationship that enables a graded increase in activity and a process to explore barriers to this increase.

1. This makes it sound as though 'pragmatic recommendations from experienced clinicians' are a poor second to 'specialist CFS/ME CBT and GET therapists (but a step up from leaving the patient to decide what activity levels are appropriate).

2. And 'evidence-based therapies'? I thought AfME just acknowledged that there is no evidence base. Which therapies are these exactly?

3. 'A process to explore barriers to this increase'? As if we (or anyone) know what the barriers to increasing activity are. If we did, we wouldn't need research funds to establish the disease mechanism. What barriers does AfME think might be explored?


@AfME, I'd like to understand why you think endorsing that BACME quote is appropriate.
 
This looks like a major turn around.

I note they say they will review their resources and information. I hope that will be done very quickly - they have a responsibility to patients to withdraw immediately any information on their website, training for doctors etc that does not reflect this new approach.

@Action for M.E. please convey my thanks to AfME for this significant turnaround. And please also pass on my concern about the statement that review of materials may take some time. I agree that it's important not to rush to rewriting everything and get it wrong again. But I think in the meantime any materials that are dubious should be withdrawn . Better no information than incorrect information.

I also share the concern expressed above about the endorsement of BACME. They are far from perfect - including for example having one of the worst proponents of the BPS approach as a speaker at their recent conference.
Sums up my thoughts thanks @Trish
 
I’m not familiar with the history or the inner working of British patient organizations, so I will formulate my remarks carefully.

According to my interpretation the wording used by Action for ME still leaves some forms of graded exercise therapy undisputed. The influential Cochrane review for example not only mentions deconditioning as rationale for GET, but also central sensitization. This theory has recently become the more popular justification for GET. It claims ME/CFS patients do experience symptom exacerbation after exercise, yet only because their central nervous system is sensitized to the feeling of pain and fatigue. So this theory claims to account for “legitimate concerns about the consequences of exercise”.

To “stabilise symptoms before any appropriate increase in activity levels is attempted” is an approach already used in some forms of GET. This is based on the (unproven) assumption that ME/CFS patients have a boom & bust' cycle of activity, which needs to be taken care of, before starting graded exercise. The approach used by the Belgian Pain in Motion research group (Nijs/Meeus) - confusingly called activity pacing self-management - uses for example a stabilizing phase of pacing as a stepping stone to graded exercise therapy. As far as I can see, the explanation of Action for ME does not provide arguments to suggest they disagree with this adapted form of graded exercise therapy.

The idea that the person with M.E./CFS should be in charge of the aims and goals of the overall management plan, is also not a game-changer. GET-proponents will claim that the patient can decide when to start the graded phase and at which baseline level etc.

Of course it is possible that Action for ME does question this form of GET and that they simply failed to articulate this position more explicitly (let’s hope so). But the fact that they refused to use the term GET, suggests there is more to it. I don’t want to be a pessimist. The fact that Action for ME has joined the opposition to the PACE-trial and explicitly says they should have invested in biomedical instead of behavioral research is definitely a positive development which I do not want to trivialize. But I hope someone with more esteem/leverage than me might ask Action for ME about their position on forms of graded exercise therapy that use central sensitization as a rationale and pacing as a stepping stone in a preceding stabilization phase.

Much like "aim to reduce and stabilise symptoms before any appropriate increase in activity levels is attempted" they are having to cede ground on playing both sides and they don't want to.
 
A positive step in the right direction. As I started reading I thought "they're not going to get everything perfect, don't be churlish now". I was even prepared to overlook

I sincerely apologise to those who feel that, in not speaking out sooner and more strongly, we have caused harm

"Feel" my arse. This is an extremely late apology, and for how many years now has SC been drawing 60 grand a year, and for what exactly, and from what exactly, while the harm continued? Anyway, mustn't be churlish. But then this heart-sinking garbage:

Evidence-based therapies emphasize a therapeutic relationship that enables a graded increase in activity and a process to explore barriers to this increase.” According to BACME ...

So still some way to go, and unfortunately no reason to stop "harumphing" yet. Still, a step in the right direction I suppose.
 
The BACME Guidance on Symptom Management that AfME linked to is a load of patronising codswallop. Yes, there's central sensitisation, trauma in childhood as a pre-disposing factor and 'daily life' responsible for illness perpetuation.

How's this for a sly wink amongst doctors:

In general, patients tend to be able to tolerate supplements better than prescribed medications, even though there is often equivalence in active ingredients.

The BACME guidance is based on CBT and GET being the evidence based treatments e.g.

Objectives:
To champion evidence-based approaches to the treatment of CFS/ME, such as those recommended in the NICE guidelines

Once a diagnosis has been made, patients should be considered for further evaluation to see if they would benefit from the evidence based treatments (CBT – cognitive behaviour therapy and GET – graded exercise therapy). Where these specialist services are not available, rehabilitation using those principles (as described later in this guide).

Therefore in addition to referral for definitive therapy (CBT and GET type interventions) patients with CFS/ME may need symptomatic remedies to help with specific symptoms whilst waiting for definitive therapy to become available and/or to become effective.

The symptom is completely relieved. Under these circumstances it makes sense to continue the drug for some time and then consider withdrawal as the patient’s overallcondition improves (perhaps in response to definitive therapy with GET or CBT).

The aim of a rehabilitation plan is to regulate bodily systems and to begin to desensitise a heightened level of sensory processing inside the body by doing a small amount (a baseline) of activity and achieving a better balance of rest in all areas of activity in daily life. Having achieved this, the challenge is to then gently build up activity over time thereby re- educating the body and increasing tolerance for exertion.

To gradually build the level of all areas of activity in daily life, as defined by the person. This may be increases in frequency, intensity, quality and/or duration. This is a consolidating, incremental approach that supports successful integration and can be sustained.

Re-introduction of activity and/or exercise.
Agreed phased, incremental increases to physical, cognitive and/or social activities.

A tool to increasing activity, e.g. through increased socialisation/regular attendance.

CFS/ME therapists can be help by focusing on baselines of activity and applying the same principles of stabilizing and then gradually increasing work.​

The supposed 'patient choice' seems to be allowing patients to choose to remain at the lowered baseline with fewer symptoms, rather than pushing on with more activity and therefore reaching a certain recovery.

I’m sure that fence was getting very uncomfortable over the last couple of years.
I don't think AfME is off the fence yet. Are they saying that CBT and GET are ineffective, or do they agree with the BACME document that they have linked to which says that they are the 'definitive therapies'?
 
the models of GET and CBT used in the PACE trial assume that M.E. is perpetuated by deconditioning (lack of fitness); however, significant studies disagree that deconditioning is the cause of M.E. and/or CFS, and is in fact a consequence of the condition
AFAIK, 2-day cpet show that on day 1 most patients have a normal function. Of course, that doesn't include more severe patients who can't undergo cpet, who would be deconditioned. So the patients with less sever ME/CFS aren't even deconditioned at all! I think it's important to say that.

According to BACME, specialist NHS M.E./CFS services should advocate collaborative work, patient-led goals and support to stabilise physiological patterns of rest, sleep, movement and diet. At the same time, psychological/emotional support should be offered, aimed at supporting patients to come to terms with being diagnosed and/or living with the condition, and to understand the factors and behaviours (eg. doing too much) that jeopardises that stabilisation.

We fully support this approach, and would add that:

  • “this is best achieved through pacing that utilizes energy conservation techniques mindful of heart rate limits. Only then can careful training of the anaerobic energy system, (ie, improving the body’s tolerance for and ability to clear lactate while increasing ATP in resting muscle) be initiated.” (Van Ness et al, Workwell Foundation, May 2018)
  • “healthcare professionals should recognise that the person with CFS/ME is in charge of the aims and goals of the overall management plan. The pace of progression throughout the course of any intervention should be mutually agreed.” (NICE guideline for M.E./CFS, 2007)
Re worwell: Yes, they claim that they can increase physical function a little bit, but it will definitely be misunderstood by most physiologists and therefore this statement is premature, IMO.

What progression? There is no need to agree to any pace of progression, because there is none. If you get better, you do more. The last thing a patient needs is pressure due to some agreement with their doctor, especially with a fluctuating condition like ME/CFS.
 
To “stabilise symptoms before any appropriate increase in activity levels is attempted” is an approach already used in some forms of GET. This is based on the (unproven) assumption that ME/CFS patients have a boom & bust' cycle of activity, which needs to be taken care of, before starting graded exercise.

This is exactly the approach that was taken with me at a UK NHS ME/CFS centre. I was instructed to establish a stable baseline and then grade my activity up from there. It proved impossible to establish a stable baseline. There was no limit to how low I could drop my activity and yet still feel like shit. I was told I was just too ill to benefit from treatment.

It worries me to see this language turning up in AfME's statement, even though there are many things in the statement that I welcome.
 
In my view this is simply repositioning themselves, now that so many people, even outside of the ME world, now know PACE was a truly terrible trial, from concept to design to handling the data.

They will continue to try to play both sides, but they need to put a little distance between themselves and their PACE pals to keep membership numbers up.

@Action for M.E., If you're listening, it's easy to denounce something (you helped happen) when everyone else has already done all the hard work proving it's bad. If you really are interested in the well being of patients and your members, prove it.

Condemn BACME, Crawley, the Lightening Process, SMILE, etc..

Otherwise, it's all too little too late.
 
I thought that the statement from Sonya was pretty good, but everything else was pretty bad.

It seems like Action for ME have realised they've made mistakes, but they don't really understand why. I think that there are entrenched problems at Action for ME which mean that it is not capable of commenting competently on research and treatment issues.

I think that it's a mistake to focus on the underlying models of CBT/GET as a problem - if therapists claimed they had different underlying models, would that suddenly make the treatments any better?

the PACE trial did not use objective measures to assess the effectiveness of CBT and GET, but instead relied on subjective measures, ie. reporting by patients, which can be unreliable

They did use a fitness test, 6mwt and employment data.

changes to the recovery criteria part-way through the trial meant that “it was possible to score below the level required for trial entry, yet still be counted as ‘recovered’” (Wilshire et al, 2016)

Only for SF36-PF and CFQ. That was all the was needed for the 'recovery' criteria used in the 2011 Lancet commentary, but the 2013 Psych Med also had additional requirements of a self-rated CGI score of 1 or 2, and a requirement that participant not fulfil every aspect of the trial entry criteria.

The full sentence from the Wilshire abstract: "Further, the final definition was so lax that on some criteria, it was possible to score below the level required for trial entry, yet still be counted as ‘recovered’." Why didn't they get this statement checked by someone like Wilshire?

The embrace of BACME is ridiculous.

BACME say "NHS M.E./CFS services should advocate collaborative work, patient-led goals". Apparently Action for ME "fully support this approach".

How can that approach be applied when patients are being misled about treatment efficacy by poorly designed trials with spun results?

This was BACME's statement on PACE:

British Association for CFS/ME (BACME) Statement on the PACE Trial results

The National Institute for Health and Clinical Excellence (NICE) has previously recommended Graded Exercise Therapy (GET) and Cognitive Behaviour Therapy (CBT) as treatments for mild and moderate categories of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) on the basis of somewhat limited evidence in the form of numerically small clinical trials. The PACE Trial represents the highest grade of clinical evidence – a large randomized clinical trial, carefully designed, rigorously conducted and scrupulously analysed and reported. It provides convincing evidence that GET and CBT are safe and effective therapies and should be widely available for patients with CFS/ME as per the NICE guidelines (www.nice.org.uk). Adaptive Pacing Therapy (APT) has not been shown to be effective as delivered within the PACE Trial, but this may differ from activity strategies promoted by CFS/ME services nationally. This trial shows that approaches aimed at staying within limits imposed by the illness are less effective than those that test such limits.

In addition to these general benefits, research has shown that some people with CFS/ME can feel much better, and increase their activity levels, by gradually increasing the amount of exercise which they do. A large research trial (The PACE Trial, White 2011) has shown that people with CFS/ME who had support from specialist therapists to gradually increase their exercise levels were more likely to report improvements in function and symptoms at the end of the year-long study.

This is how the PACE team described their work with BACME under 'engagement activities':

Description: Clinicians' conferences
Form Of Engagement Activity: A talk or presentation
Part Of Official Scheme? : Yes
Type Of Presentation: Keynote/Invited Speaker
Geographic Reach: National
Primary Audience: Health professionals
Results and Impact Several: talks at regional meetings of BACME, eg in Bristol, Newcastle, London, and keynote speaker in March 2012 for their national biennial conference.

Good feedback from clinicians and reports of implementing changes to clinical practice

Has BACME ever spoken out about the way results from PACE were spun? Or apologised for their own promotion of these results? From what I've seen, it's the opposite.

Using terms like 'collaborative' and 'patient-led' might sound nice, but they depend upon ensuring that claims made by medical professionals to patients are reasonable and founded upon a careful and critical examination of the available evidence. Misleading information about treatment efficacy destroy the ability to have a genuinely collaborative and petient-led approach to treatment, but no-one at BACME seems concerned about this.

In my view this is simply repositioning themselves, now that so many people, even outside of the ME world, now know PACE was a truly terrible trial, from concept to design to handling the data.

They will continue to try to play both sides, but they need to put a little distance between themselves and their PACE pals to keep membership numbers up.

Otherwise, it's all too little too late.

It wouldn't amaze me if this was part of a move by BAMCE to re-position themselves, distance themselves from PACE and change the way that they use language, while making fairly minimal changes to how they treat patients, maintaining their positions and careers.

Despite this being a good step in the right direction, I can't help wondering whether the best service AfME could give to the ME community would be to close themselves down as not fit for purpose, shut down their website with all its misinformation, and pass all their resources over to the ME Association so there could be one large national UK charity that provides information for patients, families and doctors.
 
I'd be interested to know who drafted this. Did they get advice from BACME? AfME seems to be tied to a lot of dodgy clinicians.

Is that tied to, used by, or influenced by?

If they are being influenced by BACME, then that is a serious concern. The implication of a patient charity being used, or allowing themselves to be used as a fake shop front.

I have tried to give them the benefit of the doubt and assumed they allowed popularity (rather than efficacy) of alternative treatments by members to inform their recommendations. With some bad advice by their medical advisors thrown in.

Edited - spelling

I don't know exactly what is going on in there - I'd love to find out.
