Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Essentials of Diagnosis and Management

Despite myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) affecting millions of people worldwide, many clinicians lack the knowledge to appropriately diagnose or manage ME/CFS. Unfortunately, clinical guidance has been scarce, obsolete, or potentially harmful. Consequently, up to 91% of patients in the United States remain undiagnosed, and those diagnosed often receive inappropriate treatment. These problems are of increasing importance because after acute COVID-19, a significant percentage of people remain ill for many months with an illness similar to ME/CFS. In 2015, the US National Academy of Medicine published new evidence-based clinical diagnostic criteria that have been adopted by the US Centers for Disease Control and Prevention. Furthermore, the United States and other governments as well as major health care organizations have recently withdrawn graded exercise and cognitive-behavioral therapy as the treatment of choice for patients with ME/CFS. Recently, 21 clinicians specializing in ME/CFS convened to discuss best clinical practices for adults affected by ME/CFS. This article summarizes their top recommendations for generalist and specialist health care providers based on recent scientific progress and decades of clinical experience. There are many steps that clinicians can take to improve the health, function, and quality of life of those with ME/CFS, including those in whom ME/CFS develops after COVID-19. Patients with a lingering illness that follows acute COVID-19 who do not fully meet criteria for ME/CFS may also benefit from these approaches.

Caring for the Patient with Severe or Very Severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) can cause a wide range of severity and functional impairment, leaving some patients able to work while others are homebound or bedbound. The most severely ill patients may need total care. Yet, patients with severe or very severe ME/CFS struggle to receive appropriate medical care because they cannot travel to doctors’ offices and their doctors lack accurate information about the nature of this disease and how to diagnose and manage it. Recently published clinical guidance provides updated information about ME/CFS but advice on caring for the severely ill is limited. This article is intended to fill that gap. Based on published clinical guidance and clinical experience, we describe the clinical presentation of severe ME/CFS and provide patient-centered recommendations on diagnosis, assessment and approaches to treatment and management. We also provide suggestions to support the busy provider in caring for these patients by leveraging partnerships with the patient, their caregivers, and other providers and by using technology such as telemedicine. Combined with compassion, humility, and respect for the patient’s experience, such approaches can enable the primary care provider and other healthcare professionals to provide the care these patients require and deserve.

Experiences of Living with Severe Chronic Fatigue Syndrome/Myalgic Encephalomyelitis

Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a rare disease with no known etiology. It affects 0.4% of the population, 25% of which experience the severe and very severe categories; these are defined as being wheelchair-, house-, and bed-bound. Currently, the absence of biomarkers necessitates a diagnosis by exclusion, which can create stigma around the illness. Very little research has been conducted with the partly defined severe and very severe categories of CFS/ME. This is in part because the significant health burdens experienced by these people create difficulties engaging in research and healthcare provision as it is currently delivered. This qualitative study explores the experiences of five individuals living with CFS/ME in its most severe form through semi-structured interviews. A six-phase themed analysis was performed using interview transcripts, which included identifying, analysing, and reporting patterns amongst the interviews. Inductive analysis was performed, coding the data without trying to fit it into a pre-existing framework or pre-conception, allowing the personal experiences of the five individuals to be expressed freely. Overarching themes of ‘Lived Experience’, ‘Challenges to daily life’, and ‘Management of the condition’ were identified. These themes highlight factors that place people at greater risk of experiencing the more severe presentation of CFS/ME. It is hoped that these insights will allow research and clinical communities to engage more effectively with the severely affected CFS/ME population.

Homebound versus Bedridden Status among Those with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Persons living with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) vary widely in terms of the severity of their illness. It is estimated that of those living with ME/CFS in the United States, about 385,000 are homebound. There is a need to know more about different degrees of being homebound within this severely affected group. The current study examined an international sample of 2138 study participants with ME/CFS, of whom 549 were severely affected (operationalized as 'Homebound'). A subsample of 89 very severely affected participants (operationalized as 'Homebound-bedridden') was also examined. The findings showed a significant association between severely and very severely affected participants within the post-exertional malaise (PEM) symptom domain. The implications of these findings are discussed.

Defining the prevalence and symptom burden of those with self-reported severe chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME): a two-phase community pilot study in the North East of England

OBJECTIVES

To define the prevalence of severe chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and its clinical characteristics in a geographically defined area of Northern England. To understand the feasibility of a community-based research study in the severely affected CFS/ME group.

DESIGN

A two-phase clinical cohort study to pilot a series of investigations in participants own homes.

SETTING

Participants were community living from the area defined by the Northern clinical network of the UK.

PARTICIPANTS

Adults with either a medical or a self-reported diagnosis of CFS/ME. Phase 1 involved the creation of a database. Phase 2: five participants were selected from database, dependent on their proximity to Newcastle.

INTERVENTIONS

The De Paul fatigue questionnaire itemised symptoms of CFS/ME, the Barthel Functional Outcome Measure and demographic questions were collected via postal return. For phase 2, five participants were subsequently invited to participate in the pilot study.

RESULTS

483 questionnaire packs were requested, 63 were returned in various stages of completion. 56 De Paul fatigue questionnaires were returned: all but 12 met one of the CFS/ME criteria, but 12 or 22% of individuals did not fulfil the Fukuda nor the Clinical Canadian Criteria CFS/ME diagnostic criteria but 6 of them indicated that their fatigue was related to other causes and they barely had any symptoms. The five pilot participants completed 60% of the planned visits.

CONCLUSIONS

Severely affected CFS/ME individuals are keen to participate in research, however, their symptom burden is great and quality of life is poor. These factors must be considered when planning research and methods of engaging with such a cohort.

Symptoms of chronic fatigue syndrome/myalgic encephalopathy are not determined by activity pacing when measured by the chronic pain coping inventory

OBJECTIVES

Chronic fatigue syndrome/myalgic encephalopathy (CFS/ME) is a chronic illness which can cause significant fatigue, pain and disability. Activity pacing is frequently advocated as a beneficial coping strategy, however, it is unclear whether pacing is significantly associated with symptoms in people with CFS/ME. The first aim of this study was therefore to explore the cross-sectional associations between pacing and levels of pain, disability and fatigue. The second aim was to explore whether changes in activity pacing following participation in a symptom management programme were related to changes in clinical outcomes.

DESIGN

Cross-sectional study exploring the relationships between pacing, pain, disability and fatigue (n=114) and pre-post treatment longitudinal study of a cohort of patients participating in a symptom management programme (n=35).

SETTING

Out-patient physiotherapy CFS/ME service.

PARTICIPANTS

One-hundred and fourteen adult patients with CFS/ME.

MAIN OUTCOME MEASURES

Pacing was assessed using the chronic pain coping inventory. Pain was measured using a Numeric Pain Rating Scale, fatigue with the Chalder Fatigue Scale and disability with the Fibromyalgia Impact Questionnaire.

RESULTS

No significant associations were observed between activity pacing and levels of pain, disability or fatigue. Likewise, changes in pacing were not significantly associated with changes in pain, disability or fatigue following treatment.

CONCLUSIONS

Activity pacing does not appear to be a significant determinant of pain, fatigue or disability in people with CFS/ME when measured with the chronic pain coping index. Consequently, the utility and measurement of pacing require further investigation.

Chronic Fatigue Syndrome: An Evaluation of an Occupational Therapy Inpatient Intervention

It has been stated that, although most chronic fatigue syndrome (CFS) patients can be treated in primary care and that cognitive behaviour therapy and prescribed, graded aerobic exercise appear to be promising in outpatient management, a minority of patients will require inpatient care (Royal Colleges of Physicians, General Practitioners and Psychiatrists 1996). To date, little has been written on the need for and impact of an inpatient approach for patients with CFS. This study builds on previous work to show how patients with complex CFS responded to a specifically designed occupational therapy inpatient programme, using the principles of cognitive behaviour therapy and graded activity.

A quasi-experimental study was carried out using current inpatients with those on the waiting list as a comparison. At 6 months following discharge, a significant difference between the groups in terms of symptoms and level of ability was not demonstrated. However, a significant effect was shown in patients' perceived health, length of time tired and management of the illness. Thirty-one (72%) of the inpatient group, compared with 10 (53%) of the comparison group, stated that they felt better than the previous year. Thirty-one (72%) of the inpatient group, compared with 7 (37%) of the comparison group, indicated better management of their illness. These findings give some evidence of the need for an inpatient CFS management programme for specific patients with complex CFS.

An Evaluation of a Chronic Fatigue Lifestyle Management Programme Focusing on the Outcome of Return to Work or Training

This article presents the results of an audit of clinical outcomes from an occupational therapist led service for patients with chronic fatigue syndrome (CFS). The service offers group outpatient lifestyle management sessions, in which patients are encouraged to restructure lifestyle patterns in order to facilitate improvements in fatigue and function.

The cohort studied consisted of 98 consecutive patients attending the service who fulfilled the 1994 Centers for Disease Control criteria for CFS. The median illness duration was 5 years. The treatment offered consisted of six group sessions in lifestyle management together with three additional review sessions. The primary outcome measure was a return by the patient to employment, voluntary work or training. The cohort was followed up at a median of 18 months using a self-report questionnaire. Among the treated patients, 42% (31/74) reported new part-time or full-time employment, voluntary work or training.

The results of this study suggest that a lifestyle management programme offered by an occupational therapist led specialist service may provide positive outcomes, in terms of a return by patients to work and training, and indicates the need for a randomised controlled trial to provide definitive evidence of this.

Illness Narrative and Chronic Fatigue Syndrome/Myalgic Encephalomyelitis: a Review

Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) remains a contentious and stigmatised condition despite its recent medical recognition as an official illness. As a chronic condition, both the devastating effect that it has upon the daily occupational functioning of these people and upon their families and the rate of prevalence in the United Kingdom suggest that occupational therapy could make a significant contribution.

This article seeks to describe and discuss the purposes that illness narratives may serve for those with CFS/ME. It is proposed that occupational therapists need to, first, acknowledge the subjective experience of those who are living with CFS/ME through sharing these narratives and, second, facilitate the process by which the voice of people with CFS/ME is heard with regard to the service provision. Only then can they claim to offer a truly client-centred service.

Severe Chronic Fatigue Syndrome (CFS/ME): Recovery is Possible

The recovery of individuals with very severe chronic fatigue syndrome/ myalgic encephalomyelitis (CFS/ME) is possible with successful multidisciplinary management. This case vignette aims to highlight the beneficial outcome of using occupational therapy lifestyle management and the Canadian Occupational Performance Measure to identify perceived problems in occupational performance and indicate change. The current management strategies in CFS/ME are discussed briefly and the challenges of the management of severe CFS/ME are described, indicating a need for a supportive team and specialist inpatient services.

In 2003, the Department of Health released funds in England to develop more widely accessible CFS/ME services. This case study illustrates a positive outcome for one individual with severe CFS/ME, following admission to a specialist inpatient facility. It is hoped that it may aid other therapists working with and developing services for people with severe presentations of CFS/ME.

Severity Scales for Use in Primary Health Care to Assess Chronic Fatigue Syndrome/Myalgic Encephalomyelitis

Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a physical and cognitive disabling illness, characterized by severe fatigue and a range of physiological symptoms, that primarily affects women. The immense variation in clinical presentation suggests differences in severity based on symptomology and physical and cognitive functional capacities. In this article, we examine a number of severity scales used in assessing severity of patients with CFS/ME and the clinical aspects of CFS/ME severity subgroups. The use of severity scales may be important in CFS/ME because it permits the establishment of subgroups that may improve accuracy in both clinical and research settings.

What is the current NHS service provision for patients severely affected by chronic fatigue syndrome/myalgic encephalomyelitis? A national scoping exercise

BACKGROUND

Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), in its most severe clinical presentation, can result in patients becoming housebound and bedbound so unable to access most available specialist services. This presents particular clinical risks and treatment needs for which the National Institute for Health and Care Excellence (NICE) advises specialist medical care and monitoring. The extent of National Health Service (NHS) specialist provision in England for severe CFS/ME is currently unknown.

OBJECTIVES

To establish the current NHS provision for patients with severe CFS/ME in England.

SETTING AND PARTICIPANTS

All 49 English NHS specialist CFS/ME adult services in England, in 2013.

METHOD

Cross-sectional survey by email questionnaire.

PRIMARY OUTCOME MEASURES

Adherence to NICE guidelines for severe CFS/ME.

RESULTS

All 49 services replied (100%). 33% (16/49) of specialist CFS/ME services provided no service for housebound patients. 55% (27/49) services did treat patients with severe CFS/ME and their interventions followed the NICE guidelines. The remaining services (12%, 6/49) offered occasional or minimal support where funding allowed. There was one NHS unit providing specialist inpatient CFS/ME provision in England.

CONCLUSIONS

Study findings highlight substantial variation in access to specialist care for patients with severe presentation of CFS/ME. Where treatment was provided, this appeared to comply with NICE recommendations for this patient group.

An occupational therapy approach to persons with chronic fatigue syndrome: part two, assessment and intervention

Chronic Fatigue Syndrome (CFS) is a highly disabling condition that significantly interferes with occupational life. Occupational therapy services are very relevant for this population. Yet, information about the assessment and treatment of CFS is almost absent from occupational therapy literature. As a result, few occupational therapists possess expertise in evaluating and providing therapy for this complex condition. This paper describes an approach to evaluating and providing services for individuals with CFS according to the Model of Human Occupation. This model offers an integrative means of understanding the synergistic and evolving relationships between motivation, values, roles, habits, functional capabilities, and the environment as they influence individuals with CFS, and it provides a framework for the types of changes required in these different domains during the rehabilitation process. A case study illustrates recommended assessment and intervention approaches.

Patients' hopes and expectations of a specialist chronic fatigue syndrome/ME service: a qualitative study

BACKGROUND

The 2007 National Institute for Health and Clinical Excellence guidelines on Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) recommend early management of the condition. Investment by the Department of Health has expanded the number of specialist U.K. CFS/ME services but there has been little research on what patients hope or expect from referral.

METHODS

A qualitative study exploring hopes and expectations of patients newly referred to a CFS/ME Service in the South of England. Interviews with 20 patients were analysed using the constant comparative method.

RESULTS

Participants hoped referral to a specialist service would clarify diagnosis, give guidance and support, assist in understanding the complexity of the illness and provide hope for the future. While many participants valued the support of their GP, all viewed referral as offering a level of specialist expertise beyond that available in primary care. Many participants expressed high levels of uncertainty about the nature of CFS/ME. While participants hoped that the service would be able to provide information and guidance, many expressed the view that more information earlier in their illness would make the waiting period less stressful and make it possible for them to do more to help themselves.

CONCLUSIONS

GP referral to a specialist service appeared to be highly valued by the participants in this study. The levels of uncertainty expressed by many patients about the nature of CFS/ME raises the issue of the role of information on CFS/ME during the early stages of the illness and suggests a need for more reassurance and positive advice during the waiting period.

Development and preliminary evaluation of a cognitive behavioural approach to fatigue management in people with multiple sclerosis

OBJECTIVES

(i) To develop a group-based intervention for the management of multiple sclerosis (MS) fatigue incorporating energy effectiveness and cognitive behavioural approaches and (ii) to undertake a process and preliminary evaluation.

METHODS

Drawing upon a literature search, a local model of good practice and the views of service users and health professionals, a manualised group-based fatigue management programme was developed, designed to be delivered by health professionals. A process and preliminary outcome evaluation was undertaken. Sixteen participants attended across two iterations. Participant feedback, obtained via a focus group and evaluation questionnaires, was used to refine the programme. Outcomes were collected pre- and post-programme (including fatigue severity, quality of life, self-efficacy).

RESULTS

Focus group feedback suggested the programme was well received, reflected in high attendance and positive ratings on evaluation questionnaires. At follow-up, despite the small sample size, there were significant improvements in perceived self-efficacy for managing fatigue.

CONCLUSION

An evidence-based fatigue management intervention has been developed and preliminary findings look promising. In the next phase we will examine whether the programme transfers satisfactorily to other centres and collect data in preparation for a randomised controlled trial (RCT).

PRACTICE IMPLICATIONS

Implications for practice will emerge when the results of our RCT are published.

Chronic Fatigue Syndrome and Occupational Disruption in Primary Care: Is There a Role for Occupational Therapy?

This paper presents the findings of a postal survey that examined the experience of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) in the primary care setting. The views of 51 general practitioners (GPs) (response rate of 30%) and 51 people that had experienced CFS/ME (response rate of 61%) were collected in an attempt to describe both the occupational disruption experienced due to CFS/ME and the current management offered in primary care, and to investigate whether there was an early intervention role for occupational therapy.

The greatest level of occupational disruption reported was in the performance of self-care and productivity tasks and the most helpful intervention reported was that of acknowledgement of the condition and its implications. The GPs rated the use of cognitive behavioural therapy and graded exercise therapy as more beneficial than medical care for CFS/ME and many offered advice on these interventions, but 57% of people with CFS/ME reported that they had received unhelpful advice and/or treatment from their GP. Currently, there is little research evidence to support any particular interventions for people with CFS/ME in primary care and the prevention of occupational dysfunction, as often seen in secondary and tertiary care, is a role that could be fulfilled by occupational therapists.

The debate: myalgic encephalomyelitis and chronic fatigue syndrome

Almost every aspect of myalgic encephalomyelitis (or encephalopathy) and chronic fatigue syndrome is the subject of disagreement and uncertainty -- something that has undoubtedly hampered recognition, understanding and research. Although the pathogenesis remains the subject of intense medical debate, a number of predisposing, precipitating and perpetuating factors are now starting to emerge. Therapeutic nihilism is no longer appropriate as there is a great deal that can be done to alleviate some of the more distressing symptoms and improve quality of life for these patients.

Cognitive behaviour group therapy for chronic fatigue syndrome: a non-randomised waiting list controlled study

BACKGROUND

It has been demonstrated that individual cognitive behaviour therapy is an effective treatment for chronic fatigue syndrome (CFS). The aim of the present study was to investigate the effectiveness of cognitive behaviour group therapy (CBGT) in an unselected group of CFS patients. Additionally, pretreatment characteristics of CFS patients who improve after CBGT were explored.

METHODS

In a non-randomised waiting list controlled design, 31 patients were allocated to CBGT and 36 to the waiting list condition. CBGT consisted of 12 two-hour sessions during 6 months. Main outcome measures were fatigue (Checklist Individual Strength) and functional impairment (Sickness Impact Profile).

RESULTS

A moderate effect on fatigue in favour of CBGT was found. For functional impairment, the effect was opposite to what was expected. Patients who improved after CBGT had less complaints at baseline compared to patients who did not improve.

CONCLUSIONS

An explanation for the moderate effect might be that during CBGT, rest and relaxation were too much emphasised. Furthermore, an unselected group of CFS patients and therapists inexperienced in CB(G)T for CFS participated. Suggestions to improve CBGT for future research are given.

Chronic fatigue syndrome: is there a role for occupational therapy?

Chronic Fatigue Syndrome (CFS) continues to evolve as a disabling phenomenon characterized by debilitating fatigue and consequential components that limit the functional ability of persons afflicted with the disease. A composite review of the current literature addresses a brief history, etiology, legitimacy, incidence and prevalence, prognosis, diagnosis, impact, and treatment of CFS. The primary focus illustrates available treatment strategies that have been incorporated into occupational therapy practice. As a profession that has made contributions to populations with chronic disease and symptoms similar to those suffering from CFS, the use of effective methods should reinforce the need for occupational therapy intervention with this population.
