EXECUTIVE SUMMARY

A summary of our report on the acceptability, efficacy and safety of Cognitive Behaviour Therapy (CBT), Graded Exercise Therapy (GET) and Pacing courses, as interventions used as management strategies for patients with ME/CFS.

It relates to the use of CBT, GET and Pacing courses by health professionals when delivered to patients on either a one-to-one basis or in a group setting.


INTRODUCTION

Evidence from patient surveys reporting experiences of the three main therapeutic approaches to management of ME/CFS have produced results which differ significantly to those in published research evidence. Large numbers of patients reported that CBT and GET were not acceptable, effective or safe. We saw it as our responsibility to investigate those reports and, if found correct, lobby for change in respect of clinical recommendations.

In 2012 we decided that a new and more detailed patient survey was required to seek to explain the factors that might contribute to patient reported outcomes. This report is the result of and contains detailed evidence from that survey.

It is our hope that this new evidence might persuade NHS England to advise the National Institute for Health and Care Excellence (NICE) to revise the current clinical guideline on ME/CFS (CG53), and also provide clearer guidance to NHS specialist services and private health practitioners on ways in which illness management advice can be made more suitable for all those affected by this illness; thus leading to improved patient reported outcomes.


METHOD

Our survey was launched in May 2012 and operated until August 2012. It was open to anyone who had/had had myalgic encephalomyelitis, chronic fatigue syndrome or post-viral fatigue syndrome, which we have called ME/CFS.

We asked about management courses and self-management which employed CBT, GET or Pacing approaches and we also canvassed the views of those who had not been offered a course, had been refused one, or had not taken up a course recommendation.

The survey was split into three sections, one each for CBT, GET and Pacing, asked 228 questions in total and was completed by 1428 respondents (though not every question was completed by every respondent).

The report is concerned with responses from those who had received a positive diagnosis from a health professional, had undertaken one-to-one or group courses (whether or not they had fully completed the recommended number of sessions) and had indicated the severity of their illness before and after their courses, and whether or not their courses were appropriate to their needs.

493 had been on a CBT course, 233 on a GET course and 226 on a Pacing course and fulfilled that criteria. Some had been on separate courses for one or more of the interventions; others had been on courses comprising multiple interventions.

We examined the effect courses were deemed to have had on illness severity, symptoms (overall and individually), disability benefits, employment and education, the appropriateness of courses in relation to individual patient needs and the effect CBT has on anxiety, depression and stress.

We also considered course availability within the NHS, suitability of session length, reasons why courses were not completed in full, the provision of course information to patients, the impact NICE Guideline CG53 (2007) has had on delivery, effectiveness of courses delivered by specialists versus non-specialists, and we compared our results against previous patient surveys.

The report contains quantitative analyses (looking at the data from various perspectives), and qualitative data (which relates to the descriptions of respondents’ experiences)


RESULTS

For this executive summary, we provide some examples – complete results and full analysis can be read later in the report:

Example A:

With regard to the effect courses had on illness severity, we found that following courses there was a substantial increase in the percentage of GET patients whose ME/CFS became severe or very severe (see Section 3, Key Findings 3:3 and chart at Appendix 2 2:4:1).

Example B:

Where patients attended a CBT, GET or Pacing course which had no overlapping elements of the other two interventions, a much higher percentage of patients reported an improvement in symptoms following their Pacing course than did those who attended either of the other courses.

CBT resulted in 91% of participants feeling their ME/CFS symptoms were unaffected or made worse, GET 88%, and Pacing 55% (see Section 3, Key Findings 3:4, chart: 3:4:2a).

Example C:

Graph 3-4-2b copy
 
 
 
 
 
 
 
 
 
 
 
 
 
 

It was clear that a much higher percentage of patients attending Pacing courses with no overlapping elements found this management approach more appropriate to their needs than did those who attended either CBT only or GET only courses.

Only a small minority of GET and CBT courses were appropriate to needs (see Section 3, Key Findings 3:4, chart: 3:4:2b).

Example D:

Symptoms were reported as having improved or as remaining unaffected by a much higher percentage of patients where therapists leading a course recognised ME/CFS to be a physical illness than where therapists believed the illness was psychological.

Symptoms were reported as having been made worse by a substantial percentage where courses were led by therapists holding this psychological belief even for Pacing (see Section 3, Key Findings 3:4, charts: 3:4:9a and 3:4:11a).

Example E:

image017
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Patients who were not offered or who were refused courses reported the main reason as being that no courses were available in their area.

The second reason was judged to be that many patients were considered unlikely to benefit from the offered courses, and also of note was a lack of access to courses and no available home-visit option (see Key Findings, Section 3:11 and Chart at Appendix 2, 2:8:1).

Example F:

For those who were on benefits, it was most notable that irrespective of the course undertaken, claims remained largely the same with few reducing or stopping their benefits.

However, net overall increases were seen in benefits following courses in CBT and GET compared to a slight decrease from those attending Pacing courses (see Key Findings, Section 3:12 and Chart at Appendix 2, 2:9:1).


CONCLUSIONS AND RECOMMENDATIONS

Cognitive Behavioural Therapy (CBT)

We conclude that CBT in its current delivered form should not be recommended as a primary intervention for people with ME/CFS.

CBT courses based on the model that abnormal beliefs and behaviours are responsible for maintaining the illness, have no role to play in the management of ME/CFS and increase the risk of symptoms becoming worse. The belief of some CBT practitioners that ME/CFS is a psychological illness was the main factor which led to less symptoms improving, less courses being appropriate to needs, more symptoms becoming worse and more courses being seen as inappropriate.

Our results indicate that graded exercise therapy should form no part of any activity management advice employed in the delivery of CBT, as this also led to a negative impact on outcomes.

There is a clear need for better training among practitioners. The data indicates that lack of knowledge and experience had a direct effect on outcomes and remained a key factor, even where courses were held in specialist clinics or elsewhere given by therapists with an ME/CFS specialism.

However, our results did indicate that, when used appropriately, the practical coping component of CBT can have a positive effect in helping some patients come to terms with their diagnosis and adapt their lives to best accommodate it.

CBT was also seen to have a positive effect in helping some patients deal with comorbid issues – anxiety, depression, stress – which may occur at any time for someone with a long-term disabling illness.

An appropriate model of CBT – one that helps patients learn practical coping skills and/or manage co-morbid issues such as those listed above – could be employed, where appropriate, for ME/CFS as it is for other chronic physical illnesses such as multiple sclerosis, Parkinson’s disease, cancer, heart disease, and arthritis and we recommend all patients should have access to such courses as well as access to follow-up courses and/or consultations as and when required.

Graded Exercise Therapy (GET)

We conclude that GET should be withdrawn with immediate effect as a primary intervention for everyone with ME/CFS.

One of the main factors that led to patients reporting that GET was inappropriate was the very nature of GET itself, especially when it was used on the basis that there is no underlying physical cause for their symptoms, and that patients are basically ill because of inactivity and deconditioning.

A significant number of patients had been given advice on exercise and activity management that was judged harmful with symptoms becoming worse or much worse and leading to relapse. And it is worth noting that despite current NICE recommendations, a significant number of severe to very severe patients were recommended GET by practitioners and/or had taken part in GET courses.

The other major factor contributing to worsening symptoms was the incorrect belief held by some practitioners that ME/CFS is a psychological condition leading to erroneous advice that exercise could overcome the illness if only patients would ‘push through’.

We recognise that it is impossible for all treatments for a disease to be free from side-effects, but if GET was a licensed medication, we believe the number of people reporting significant adverse effects would lead to a review of its use by regulatory authorities.

As a physical exercise-based therapy, GET may be of benefit to a sub-group who come under the ME/CFS umbrella and are able to tolerate regular and progressive increases in some form of aerobic activity, irrespective of their symptoms. However, identifying a patient who could come within that sub-group is problematic and not possible at present.

Some patients indicated that they had been on a course which had a gentle approach of graded activity rather than a more robust and structured approach of graded physical exercise. There were some reports that patients were told they should not exercise when they felt too unwell to do so. These led, for some, to an improvement in symptoms or to symptoms remaining unaffected.

However, we conclude that GET cannot be regarded as a safe and effective form of treatment for the majority of people with ME/CFS. The fact that many people, including those who consider themselves severely affected, are being referred to specialist services for an intervention that makes them either worse or much worse is clearly unacceptable and in many cases dangerous.

GET should therefore be withdrawn by NICE and from NHS specialist services as a recommended treatment with immediate effect for everyone who has a diagnosis of ME/CFS. This advice should remain until there are reliable methods for determining which people who come under the ME/CFS umbrella are likely to find that GET is a safe and effective form of management.

Pacing

Pacing was consistently shown to be the most effective, safe, acceptable and preferred form of activity management for people with ME/CFS and should therefore be a key component of any illness management programme.

For some, improvement may be a slow process so, whilst they may be somewhat better by the end of a course, the improvement is not enough to take them into a better category of severity for some time, perhaps not until they have self-managed their illness for a few years.

The benefit of Pacing may relate to helping people cope and adapt to their illness rather than contributing to a significant improvement in functional status. Learning coping strategies can help make courses more appropriate to needs even if they do not lead to immediate or even longer term improvement in symptoms. Importantly, it can prevent symptoms from becoming worse.

Pacing can be just as applicable to someone who is severely affected, as to someone who is mildly or moderately affected, although additional measures need to be taken to ensure that a person who is severely affected has equal access to services.

As with CBT, there must be better training for practitioners who are to deliver such management courses. Proposed increases in activity, both mental and physical, must be gradual, flexible and individually tailored to a patient’s ability and circumstance and not progressively increased regardless of how the patient is responding and therapists must be taught to recognise that.

All patients should have access to suitable courses, follow-up courses and/or consultations as and when required.

Note: Please see Sections 4 and 5 for our full conclusions and recommendations. Caveats are set out in Section 6.
