Monday, October 23, 2006 Comprehensive MEA response to NICE Guideline on ME/CFS (draft 2) MAY BE REPOSTED This second draft takes account of the very helpful comments and feedback that has been sent in by people with ME/CFS over the past week. Further comments to the MEA are most welcome - see notes at the end. A further draft will be prepared next week. SECOND DRAFT Following on from our previous statements on the September draft of the NICE guideline on ME/CFS, and our summary of the meeting held at NICE on Thursday 5 October, the MEA has now produced a second draft of the comprehensive response that we intend to send to NICE at the end of this stage in the consultation process. This response takes account of all the feedback that the MEA has received so far and the discussion that took place at NICE on 5 October. Thank you to everyone who has sent in comments. As a stakeholder in the guideline development process the MEA has a duty to consult with its members and produce a response that reflects their views. So we want to know if you feel that our response is appropriate and constructive. We want to know if there are any omissions or areas where we have been too critical, or not critical enough. We also want to know if there are any areas where we should be praising the guideline. In April 2007 NICE will publish a final version of a guideline on ME/CFS. This will have a major effect on how your illness is going to be managed for years to come. The MEA believes that the current attempt is seriously flawed and is not therefore fit for purpose. Over the coming weeks and months we need to do all we can to make changes while there is still an opportunity to do so. _______________________________________________________________________________________ MEA RESPONSE TO THE SEPTEMBER DRAFT The ME Association (MEA) has carefully considered the contents of this draft. As a stakeholder in the guideline development process we have actively sought the views of our members over the past few weeks as well. We have also taken note of the responses to our criticisms that were made at the meeting with NICE on Thursday 5 October. The comments below represent the outcome of this extensive consultation process. OVERALL CONCLUSIONS The MEA fully supports the view that a guideline on the assessment and management of ME/CFS should be prepared by NICE and made available to all health professionals in the UK. Such a guideline must reflect the wide variety of clinical presentations and pathophysiological mechanisms that come under the ME/CFS umbrella. Above all, it must be acceptable to people who have this illness. Overall, we feel that the current (ie September 2006) version of the guideline that has been prepared by NICE is unfit for purpose and we would not be willing to endorse it. We have five major disagreements. a.. First involves the unbalanced coverage of CBT and GET. a.. Second is the failure to provide any meaningful advice on management during the acute and very early stages of the illness before a firm diagnosis of ME/CFS has been made. a.. Third is the failure to provide any meaningful advice on symptomatic management as the illness enters a more chronic stage. a.. Fourth is the way in which it deals with issues affecting the severely affected a.. Fifth is the failure to acknowledge the WHO classification of ME/CFS (and PVFS) as being neurological disorders (in section G93.3 of ICD 10) - a position that the Department of Health also accepts - and instead adopts a new and much wider clinical definition of ME/CFS that includes almost anyone with chronic unexplained fatigue. We will first elaborate on these five objections in more detail: 1 A VERY UNBALANCED ACCOUNT OF THE BENEFITS OF CBT AND GET (section 1.3.1) Our principal disagreement involves the way in which almost all of the management section is devoted to a manual-like approach that sets out how the authors believe that cognitive behaviour therapy (CBT) and graded exercise therapy (GET) should be used as an automatic first line treatment for almost everyone who has mild to moderate ME/CFS. The sections on CBT and GET contain numerous recommendations on how to deal with specific management problems - most of which are based on opinion rather than the type of evidence based medicine that normally dominates a NICE guideline. Some of the advice on non-pharmacological management contains sensible and common sense suggestions. We already recommend some of these coping strategies in our own self-help literature. But there is no reason why this type of advice has to be given by specially trained behaviour therapists in hospital. Where the advice is sensible, and not based purely on the psychosocial model of abnormal illness beliefs and behaviour, it should form part of a self-help or Expert Patient management programme. This sort of advice could easily be given out in a primary care setting - where most people with ME/CFS are, and will continue to be managed. However, much of the coverage here is seriously flawed because the opinions of those who are obviously very enthusiastic about the overall value of hospital-based CBT and GET are given undue emphasis whereas any form of critical opinion from people who have been treated with these approaches is simply ignored. The Chief Medical Officer's report adopted a trident approach to deal with this difficult issue whereby it took note of opinion from clinicians and patients, as well as the results from published research studies, when it came to dealing with CBT and GET. This is crucial because patient opinion submitted to the CMO report indicated that the results for CBT were not at all impressive with around 65% saying that this approach had not been helpful. And around 50% of people who had been placed on a graded exercise regime reported that this had made their condition 'worse'. NICE has clearly not grasped the fact that the treatment trials being quoted to support the use of CBT and GET have only used relatively small numbers of carefully selected patients, have generally been carried out in tertiary care centres that support the psychosocial model of ME/CFS causation, and in some cases have had quite high drop-out rates (37% in one GET trial). Our feedback in relation to GET dropouts is that some of these people have gone on to relapse as a result of the exercise programme - but this is never made clear in published results. While preparing this response we have received feedback from someone who has recently been treated at an internationally recognised centre where this type of behavioural research is carried out. This person has stated that when someone cannot build up the exercises in the speed that the centre require, they are then told that they are not motivated enough to follow the programme and have to leave We would be willing to forward the complete response to NICE if requested. CBT With regard to CBT (sections 1.3.1.11-13), we believe it is completely unacceptable to imply that everyone with mild to moderate ME/CFS needs to take part in a hospital-based CBT programme that includes an underlying assumption that symptoms are maintained by factors such as abnormal illness beliefs and behaviour. While there are some people who come under the diagnostic umbrella of CFS who do fit the psychosocial model of illness perpetuation, there are many others who do not, have no psychiatric co-morbidity, are well motivated, and are doing everything they can to try and get better. They would, quite rightly, object to such an approach to their management. The Guideline Development Group (GDG) should also take note of the most recent research study on CBT. This found that CBT did not offer any significant overall benefit when compared to education and support and standard medical care (reference: Cognitive behaviour therapy in chronic fatigue syndrome: a randomised controlled trial of an outpatient group programme. Health Technology Assessment. 2006 Oct; 10: number 37 - available on-line at: http://www.hta.ac.uk/fullmono/mon1037.pdf). Neither does NICE appear to appreciate that counselling may well be just as effective as CBT in some instances. Two relevant references are: Chronic fatigue in general practice: economic evaluation of counselling versus cognitive behaviour therapy. British Journal of General Practice 2001; 51: 15-18. Chronic fatigue in general practice: is counselling as good as cognitive behaviour therapy? A UK randomised trial. British Journal of General Practice 2001; 51: 19-24. GET We have a number of major concerns about the information being given on GET (sections 1.3.1.14 - 18). Our first concern relates to the word exercise. Exercise is, of course, a completely misleading term for energy management in the severely affected group. It is also inappropriate for most people in the moderately affected group. It may or may not be appropriate in mild cases. The unqualified and frequent use of the term exercise clearly implies that exercise is the key to recovery and that rest/relaxation is generally harmful. NICE only have to look at the press coverage of the York systematic review in the Journal of the Royal Society of Medicine to see that this is how the media is already interpreting this type of advice. The same sort of over-simplistic interpretation will be made by most doctors who have no special interest in ME/CFS. What is required is a name and a practical approach that advises people with ME/CFS on how to achieve a sensible and flexible balance between activity or energy management (not exercise) and rest. This will depend on the stage, severity and variability of their condition - as we point out in some detail in our own information literature. Some people may need to increase their activity levels whereas others may actually need to reduce them, especially in the early weeks and months following an acute onset - this is not what graded exercise implies. Our second concern relates to the way in which the guideline appears to have dealt with energy/activity management during the very early stages of this illness (ie first few weeks and months) before a firm diagnosis of ME/CFS has been made. At this stage we believe that a period of appropriate rest and convalescence is essential (we are not advocating that people go to bed and stay there) and that inappropriate exercise could well produce a further deterioration. Is NICE really advocating graded exercise during the very early stages of ME/CFS? This appears to be the case in section 1.2.1.10. Our third concern relates to what is commonly referred to as the 'glass ceiling' effect whereby people with ME/CFS often make a degree of improvement over the prolonged course of time, but then reach a point at which they are unable to increase their physical activity - despite high levels of motivation. The guideline does not even acknowledge this situation - presumably on the assumption that graded exercise will eventually return almost everyone to normal health. Our fourth concern relates to the advice that activity levels should largely be maintained during a period of relapse or setback (section 1.3.1.20). We believe this advice is over simplistic and potentially dangerous, and is once again based on opinion rather than any sound evidence. We do not believe that spending a few days resting in bed during a significant relapse of symptoms, certainly one caused by an infection, is going to be harmful or result in deconditioning. This is the way in which many people with ME/CFS successfully cope with a relapse and we believe it would be irresponsible to ignore the views of patients yet again. We also believe that NICE has not taken appropriate note of several research studies which refute the role of deconditioning in the perpetuation of symptoms. The section covering relapse or setback is curious in that while it provides advice on how to cope with a relapse/setback it fails to include a list of very common causes of relapse (ie infection, over-exertion, trauma, surgery and general anaesthetics, some types of vaccination). This is important information that doctors ought to be aware of and passing to their patients. CBT AND GET The sections on CBT and GET are unbalanced and contain advice that is potentially harmful for a significant proportion of people who come under the ME/CFS umbrella. We cannot therefore endorse them. Instead, we would like to see a guideline that advocates the type of common sense, self-help strategies (ie pacing their activities according to stage and severity) that have been repeatedly endorsed by people with ME/CFS. This is an approach that could be incorporated into primary care management and/or an Expert Patient programme, and we find it strange that the Expert Patient Programme in relation to ME/CFS is not even mentioned in the shortened version, which will presumably form the basis for what is sent out to health professionals. We also wonder whether NICE is living in the real world. The clear implication being given in this guideline (key priorities section on p6/48) is that if people with mild to moderate ME/CFS want to improve then they need to be referred by their GP to a multidisciplinary hospital-based ME/CFS service that has expertise in CBT and GET. NICE acknowledges that these services cannot be delivered by general practitioners. But where is the money going to come from to assess and treat around 180,000 people with ME/CFS in the mild to moderate category? If an assessment and course of CBT and/or GET costs around £1,000, the total cost to the NHS would be around £180 million. And where are all the cognitive behaviour therapists going to come from? CBT services are already in a position where they cannot cope with a rapidly increasing referral rate for common psychiatric conditions such as anxiety and depression - a steadily worsening situation that NICE has been well aware of for some time. 2 A FAILURE TO PROVIDE INFORMATION ON THE VERY EARLY STAGES OF THE ILLNESS Our second major disagreement concerns the way in which the guideline has almost completely ignored (apart from section 1.2.10) what happens in the first four months before a diagnosis of ME/CFS is confirmed. Whilst we agree that a period of time needs to elapse before the diagnostic label of ME/CFS is used, there are a number of crucial points that need to be discussed in relation to how these patients should be managed during the very early stages (ie the first few weeks and months). On the question of labelling, the 2005 ME Alliance report into early diagnosis suggested that there are appropriate names that could be used while the diagnosis of ME/CFS is being considered - one example being a post-viral fatigue syndrome. But what is far more important is the fact that advice on aspects such as sleep disturbance and energy management is likely to quite differ quite significantly from that offered once the illness enters a more chronic stage. In regard to sleep, excessive sleep (hypersomnia) is very common at this stage and may well form a crucial part of a natural recovery process. We know of no evidence to suggest that people who are needing to sleep for a long period of time at night following an acute infection should be coerced into adopting a more normal pattern of sleeping (as in 1.3.2.1). Anecdotal evidence is overwhelmingly in favour of a period of carefully monitored rest during the very early stages, something that may include a period of bed rest, followed by convalescence. Exercise in the normal sense of the word usually has little or no role to play during this very early stage. In fact, an inappropriate exercise programme is very likely to make the illness worse. 3 A FAILURE TO PROVIDE AN ADEQUATE DESCRIPTION OF MANY IMPORTANT ASPECTS OF MANAGEMENT (mainly section 1.3.4) Our third major disagreement is that having spent most of the guideline recommending CBT and GET, the remainder contains a totally inadequate review of all the other aspects of management - many of which are extremely important to patients, and are likely to be dealt with in primary care rather than hospital-based services. In particular, the almost non-existent coverage of pain, which for some people is the most disabling aspect of their illness, is very poor - especially when this is compared to the vast amount of space given to sleep disturbance. In other words, there is very little of practical value in this guideline for general practitioners and members of the primary healthcare team - who are likely to remain the main source of information, advice and support for people with ME/CFS. 4 ISSUES AFFECTING THE SEVERELY AFFECTED (mainly section 1.4) Although the guideline acknowledges that its recommendations regarding CBT and GET do not apply to the severely affected, we feel that the information that has been supplied does not take account of the enormous difficulties currently being experienced by many people in this group when it comes to accessing either hospital-based or domiciliary-delivered medical care, obtaining practical support, and being refused one or more component of the disability living allowance because both lay and medically qualified assessors have received misinformation about the nature of this illness. The description of severe ME/CFS (pp 4 - 5 of the short version) needs to include the type of more severe neurological symptoms - ie blackouts, atypical convulsions, loss of speech and swallowing necessitating tube feeding - that are prominently referred to in section 4.2.1.2 of the CMO report. 5 DIAGNOSTIC CRITERIA FOR ME/CFS (section 1.2) We are very concerned at the way in which the guideline has modified the current Fukuda research criteria for CFS (section 1.2.1.2) to produce a new clinical criteria that extends the boundaries of what currently constitutes ME/CFS (ie chronic unexplained fatigue + one other symptom). Many clinicians and researchers believe that the existing research criteria are already far too wide and as a result CFS has become a dustbin diagnosis for anyone with unexplained chronic fatigue. The diagnostic criteria proposed by NICE means that almost anyone with unexplained chronic fatigue, or feeling 'tired all the time' will now be diagnosed as having ME/CFS. The practical result is that hospital-based services, which are still virtually non-existent in some parts of the UK, or are struggling to cope with their existing workload in others - will be flooded with referrals for people with unexplained chronic fatigue. It makes no sense whatsoever to advocate what is basically a 'one treatment fits all' approach to the extremely heterogeneous range of illness presentations that comes under the existing ME/CFS umbrella. To try and do this to everyone with unexplained chronic fatigue indicates a very serious lack of judgement. And while we appreciate that the aetiology and pathogenesis of ME/CFS falls outside the NICE guideline remit, the situation regarding ME/CFS is unique in that a significant proportion of doctors still do not even accept that this illness exists as a distinct clinical entity (reference: Primary healthcare provision and Chronic Fatigue Syndrome: a survey of patients' and General Practitioner's beliefs. BMC Family Practice 2005; 6: 49; epublication: http://www.biomedcentral.com/content/6/1/49). So there must be reference to some of the important neuroradiological, neuroendocrine and neuroimmunological research findings that support the World Health Organisation classification of ME/CFS as a neurological disorder. There should also be some reference to the important new research into gene expression that is being carried out in both the UK and the USA. This has already identified abnormalities in gene expression which may be characteristic of ME/CFS - a finding that could, of course, lead to a diagnostic test and specific forms of treatment. We are disappointed to find that the Guideline Development Group (GDG) appear to have totally rejected the way in which the Canadian Guidelines have, quite sensibly, moved towards a much tighter clinical definition that clearly recognises the importance of sub-grouping under the ME/CFS umbella, and recommends that individual differences in symptoms and signs should play an important role in how an individual patient should be managed. If NICE fails to take note of these crucial points relating to causation and subgrouping in formulating a new clinical criteria, ME/CFS will continue to be trivialised as a dustbin diagnosis with patients being incorrectly labelled as having some sort of psychosomatic or somatiform disorder. As a result, people with ME/CFS will not receive the individual approach to management that they deserve and this will add to, rather than alleviate, the cost of health and social service provision. We now move on to comment on some of the other conclusions and recommendations: GENERAL PRINCIPLES OF CARE (section 1.1) The is the one and only area where we find the content to be generally balanced, helpful and sensible - as it sets out the common sense protocols that should govern the management of any chronic disabling illness. We are particularly pleased to see that information regarding the issue of informed consent has been included here. However, the value of the advice in this section is obviously dependent on the quality of the advice that is contained elsewhere in the guideline. CLINICAL ASSESSMENT The failure to include a compehensive list of illnesses that ought to be considered before the diagnosis is confirmed is a serious omission - as is the failure to point out that there are important clinical and research findings that differentiate ME/CFS from depression. Where symptoms are being discussed in relation to disease severity (eg on page 5 of the shortened version) it should be pointed out, as was done in section 4.2.1.2 of the CMO report, that some people with more severe ME/CFS may have neurological symptoms and signs such as those already referred to. With regard to the investigation of people with a possible diagnosis of ME/CFS: Some of the recommendations regarding the investigation of people with a possible diagnosis of ME/CFS in section 1.2.2 suggest that the authors are not in touch with the sort of information that patients are taking to their doctors regarding diagnostic tests. For example, having funded research into the value of investigations involving RNaseL (for antiviral activity) and chronic fatigue syndrome urinary markers (CSFUMs), the ME Association is surprised to find no mention of these tests. We are also concerned at the lack of emphasis regarding the need to further investigate people who, while they fit the diagnosis of ME/CFS, still have a symptom or symptoms, which is/are more prominent than is normally found in this illness. For example, the need to exclude sarcoidosis in someone who also has respiratory symptoms. Or systemic lupus and parvovirus infection in someone with joint pains. Or multiple sclerosis where neurological symptoms and signs are difficult to differentiate between the two - as does sometimes happen. Or an assessment for possible sleep apnoea, with an Epworth sleepiness score, where daytime sleepiness is excessive or comes on sudddenly. There also needs to be far more information on where extended investigation is required from points that are gathered during the routine history taking (eg a positive response to a past history of blood transfusion prior to 1991 indicates the need to check hepatitis C status). And why is the estimation of creatine kinase (section 1.2.2.2) only recommended in children when it may be a marker of a muscle disease in adults? With regard to the physical examination: We are perplexed as to why there is no mention of clinical examination in the diagnostic assessment - in particular the assessment of problems such as dysequilibrium where a Romberg test or Fukuda test (for vestibular function) may demonstrate abnormal findings. Equally, people with symptoms suggesting postural hypotension should have their blood pressure checked lying and standing, and may in some circumstances require hospital based investigations. The various fibromyalgia trigger points need to be checked in those patients who have a fibromyalgic component. PROGNOSIS The very short sections on prognosis (1.2.3.3 and 1.2.4.3) are inadequate and fail to provide an accurate overall picture of current research evidence on prognosis. While we accept that an approach of cautious optimism, especially early on, should be adopted, the overall impression being given of a generally good prognosis is not consistent with published evidence. We suggest that the Guideline Development Group refer to the information on prognosis that is provided in section 1.4.3 of the CMO report. SYMPTOMATIC RELIEF AND PHARMACOLOGICAL TREATMENT (section 1.3.4) This section is hopelessly inadequate because, for many people with ME/CFS, providing effective management for one or more of their symptoms can be far more imprtant than the contribution of lifestyle management.. People with ME/CFS have a number of symptoms - pain, sleep disturbance, gastric symptoms - where a combination of self-help strategies and medication can often be very helpful. We do not understand why the guideline cannot provide more detailed information on the sort of approaches that can and should be given to patients. We have already referred to pain control, which for some is the most disabling aspect of having ME/CFS, but there are numerous other symptoms where symptomatic relief plays an important role in any management programme. We enclose some examples of MEA self-help literature on pain relief and our ABC of symptomatic management to illustrate what could actually be done here. DIET AND NUTRITION (section 1.3.5) Again, this is hopelessly inadequate - especially in view of the fact that people with ME/CFS are very interested in dietary approaches and are going to ask questions about what may or may not be helpful. They clearly need straightforward and sensible advice that covers a wide area of dietary management, along with advice on the vitamins, minerals and supplements that are extensively used and recommended to people with ME/CFS. Why, for example, is there no information about the reasons why some people (especially those with self-imposed dietary restrictions) with ME/CFS could be at increased risk of developing osteoporosis and how diet may be relevant here. Why is there no mention about the value of complex carbohydrates in helping to stabilise blood sugar levels? Why is there no mention of the importance of a good fluid intake? - especially in relation to those who have postural hypotension or orthostatic intolerance. Why is there no mention of simple self-help approaches that can help in the management of nausea (eg use of ginger) or the use of drugs such as ondansetron if this is more severe. Why is is there no mention of EPA supplements, which are probably the most popular supplement currently being used by people with ME/CFS. While we accept that there have been no randomised controlled trials to support the use of EPA, it is untrue to say that there is 'no evidence' in relation to this supplement (reference: The use of eicosapentaenoic acid in the treatment of chronic fatigue syndrome. Prostaglandins, Leukotrines and Essential Fatty Acids 2004; 70: 399 - 401). It is also unhelpful to simply state that 'Exclusion diets are not generally recommended for the management of CFS/ME' when irritable bowel symptomatology is quite common in this illness and there is good evidence to show that exclusion diets can be helpful in identifying food intolerances - where these occur in IBS. This section should also include advice about not going on a gluten free diet before a screening test for coeliac disease has been carried out. We could go on. ALTERNATIVE AND COMPLEMENTARY APPROACHES (section 1.3.6) Again, this section is hopelessly inadequate and appears from the first sentence - 'There are no complementary therapies that treat CFS/ME for adults and children and their use is not recommended' - to be very dismissive about any aspect of alternative medicine. With the lack of recognition, or limited management input from many NHS practitioners, people with ME/CFS have been spending large amounts of time and money in the alternative health sector. The pros and cons of the popular alternative treatments - eg anticandida regimes; dubious allergy tests and treatments, Reverse therapy - commonly aimed at people with ME/CFS must be properly reviewed, and where necessary discredited. Approaches such as acupuncture for pain relief, which can be supported by some degree of clinical evidence, need to be included in a fair and balanced discussion. SERIOUS OMISSIONS As the CMO report acknowledged, the management of ME/CFS crosses many boundaries. It is not just dealing with a wide range of symptoms. The NICE guideline, while acknowledging that other management issues exist, almost completely ignores what could and should be done in these areas. State sickness and disability benefits, for example, are a major source of worry for people with ME/CFS with many currently have to go to appeal in order to obtain benefits to which they should be entitled. Any guideline on management must, therefore, contain a section on state benefits, and make it clear that where ME/CFS is concerned people should be entitled to Incapacity Benefit and Disability Living Allowance where there is a genuine need. It also needs to be pointed out that ME/CFS has been recognised as a disease that can be covered by the Disability Discrimination Act, and that this can be very useful in relation to employment and education. LEGAL ISSUES The medical defence organisations have repeatedly warned doctors that prescriptions for exercise must be given with exactly the same care as with a prescription drug. Failure to do so is likely to result in litigation if harm occurs as a result of inappropriate advice. The MEA continues to receive reports from people with ME/CFS whose condition has relapsed following inappropriate advice about exercise and as a result we believe that the guideline must include this warning if it continues to use the term exercise - even when what is being referred to is activity or energy management. UNHELPFUL OR INAPPROPRIATE LANGUAGE Section 1:3:1:3 'Where the adult or child's main goal is to return to normal activities....' Many people will find this offensive as it implies that there is a substantial proportion of people who do not want to return to normal activities. The statement thereforet reinforces the prejudices about sick role behaviour held by some health professionals. TWO FINAL POINTS 1 We welcome the inclusion of information about informed consent but feel that the guidance needs to make it clear, as did the CMO report in section 4.4.2, that benefit provision must not be made conditional on agreeing to participate in a particular form of treatment. 2 The guidance, certainly in the shortened version, repeats itself at times to no added effect. CONCLUDING REMARKS In sending in this response as a stakeholder in the guideline development process, the MEA has consulted widely with its members and reflected their very strong views on the composition of the current draft. We find it hard to imagine another situation where a group of people, many of whom have little or no direct experience in the clinical care of an illness they are advising on, have produced such a poor quality guideline. We cannot understand why the views of people with ME/CFS and their charity representatives are not being listened to. Unless NICE takes on board what the stakeholders representing patient opinion have to say, they will have failed the stakeholder principle - something that government continually tells us is at the heart of the consulting and listening process. If this draft guidance becomes definitive guidance for health professionals in April 2007, it will be a very sad day for people with ME/CFS.
