Chronic fatigue syndrome: sufferers' evaluation of medical support

The need for a standardized conceptual term to describe invalidation of patient symptoms

In this paper, I comment on a growing literature documenting that many patients perceive their symptoms have been dismissed, ignored, not taken seriously, not believed, etc. (i.e. invalidated) by healthcare providers. I provide a narrative review of research reporting on this patient-provider phenomenon, invalidation of patient symptoms, in various illness contexts in order to highlight the variability concerning how scholars have been referring to the seemingly same phenomenon. Next, I discuss the challenges this variability poses for scholarship, including how it precludes the ability to build on our understanding of how it contributes to the patient experience and related health outcomes. I conclude with recommendations for future research.

A Literature Review of GP Knowledge and Understanding of ME/CFS: A Report from the Socioeconomic Working Group of the European Network on ME/CFS (EUROMENE)

Background and Objectives: The socioeconomic working group of the European myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) Research Network (EUROMENE) has conducted a review of the literature pertaining to GPs’ knowledge and understanding of ME/CFS; Materials and Methods: A MEDLINE search was carried out. The papers identified were reviewed following the synthesis without meta-analysis (SWiM) methodology, and were classified according to the focus of the enquiry (patients, GPs, database and medical record studies, evaluation of a training programme, and overview papers), and whether they were quantitative or qualitative in nature; Results: Thirty-three papers were identified in the MEDLINE search. The quantitative surveys of GPs demonstrated that a third to a half of all GPs did not accept ME/CFS as a genuine clinical entity and, even when they did, they lacked confidence in diagnosing or managing it. It should be noted, though, that these papers were mostly from the United Kingdom. Patient surveys indicated that a similar proportion of patients was dissatisfied with the primary medical care they had received. These findings were consistent with the findings of the qualitative studies that were examined, and have changed little over several decades; Conclusions: Disbelief and lack of knowledge and understanding of ME/CFS among GPs is widespread, and the resultant diagnostic delays constitute a risk factor for severe and prolonged disease. Failure to diagnose ME/CFS renders problematic attempts to determine its prevalence, and hence its economic impact.

Understanding the economic impact of myalgic encephalomyelitis/chronic fatigue syndrome in Ireland: a qualitative study

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling and complex chronic disease of unknown origin, whose symptoms, severity, and progression are extremely variable. Despite being relatively common, the condition is poorly understood and routine diagnostic tests and biomarkers are unavailable. There is no evidence on the economic impact of ME/CFS in Ireland. Methods: Adopting a patient and public involvement approach, we undertook three semi-structured focus groups, which together included 15 ME/CFS patients and 6 informal carers, to consider costs related to ME/CFS in Ireland, including how and why they arise. Focus groups were audio-recorded and transcribed verbatim, and we employed thematic analysis following the approach set out in Braun and Clarke (2006).   Results: Themes from the data were: (1) Healthcare barriers and costs; (2) Socioeconomic costs; (3) Costs of disability; and, (4) Carer-related costs. Patient participants described a range of barriers to effective healthcare that led to extra costs, including delays getting a diagnosis, poor awareness/understanding of the condition by healthcare professionals, and a lack of effective treatments. These were linked to poor prognosis of the illness by participants who, as a result, faced a range of indirect costs, including poorer labour market and education outcomes, and lower economic well-being. Direct extra costs of disability were also described, often due to difficulties accessing appropriate services and supports. Informal carer participants described a range of impacts, including time costs, burnout, and impacts on work and study. Conclusions: The data suggests that ME/CFS patients face a wide range of costs, while there are also wider societal costs in the form of costs to the health service, lost productivity, and impacts on informal carers. These results will inform ongoing research that aims to quantify the economic burden of ME/CFS in Ireland and raise awareness of the illness amongst healthcare providers and policymakers.

Behavioural modification interventions for medically unexplained symptoms in primary care: systematic reviews and economic evaluation

BACKGROUND

The term 'medically unexplained symptoms' is used to cover a wide range of persistent bodily complaints for which adequate examination and appropriate investigations do not reveal sufficiently explanatory structural or other specified pathologies. A wide range of interventions may be delivered to patients presenting with medically unexplained symptoms in primary care. Many of these therapies aim to change the behaviours of the individual who may have worsening symptoms.

OBJECTIVES

An evidence synthesis to determine the clinical effectiveness and cost-effectiveness of behavioural modification interventions for medically unexplained symptoms delivered in primary care settings was undertaken. Barriers to and facilitators of the effectiveness and acceptability of these interventions from the perspective of patients and service providers were evaluated through qualitative review and realist synthesis.

DATA SOURCES

Full search strategies were developed to identify relevant literature. Eleven electronic sources were searched. Eligibility criteria - for the review of clinical effectiveness, randomised controlled trials were sought. For the qualitative review, UK studies of any design were included. For the cost-effectiveness review, papers were restricted to UK studies reporting outcomes as quality-adjusted life-year gains. Clinical searches were conducted in November 2015 and December 2015, qualitative searches were conducted in July 2016 and economic searches were conducted in August 2016. The databases searched included MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and EMBASE. Updated searches were conducted in February 2019 and March 2019.

PARTICIPANTS

Adult participants meeting the criteria for medically unexplained symptoms, including somatoform disorders, chronic unexplained pain and functional somatic syndromes.

INTERVENTIONS

Behavioural interventions were categorised into types. These included psychotherapies, exercise-based interventions, multimodal therapies (consisting of more than one intervention type), relaxation/stretching/social support/emotional support, guided self-help and general practitioner interventions, such as reattribution. Evidence synthesis: a network meta-analysis was conducted to allow a simultaneous comparison of all evaluated interventions in a single coherent analysis. Separate network meta-analyses were performed at three time points: end of treatment, short-term follow-up (< 6 months since the end of treatment) and long-term follow-up (≥ 6 months after the end of treatment). Outcomes included physical and psychological symptoms, physical functioning and impact of the illness on daily activities. Economic evaluation: within-trial estimates of cost-effectiveness were generated for the subset of studies where utility values (or quality-adjusted life-years) were reported or where these could be estimated by mapping from Short Form questionnaire-36 items or Short Form questionnaire-12 items outcomes.

RESULTS

Fifty-nine studies involving 9077 patients were included in the clinical effectiveness review. There was a large degree of heterogeneity both between and within intervention types, and the networks were sparse across all outcomes. At the end of treatment, behavioural interventions showed some beneficial effects when compared with usual care, in particular for improvement of specific physical symptoms [(1) pain: high-intensity cognitive-behavioural therapy (CBTHI) standardised mean difference (SMD) 0.54 [95% credible interval (CrI) 0.28 to 0.84], multimodal SMD 0.52 (95% CrI 0.19 to 0.89); and (2) fatigue: low-intensity cognitive-behavioural therapy (CBTLI) SMD 0.72 (95% CrI 0.27 to 1.21), relaxation/stretching/social support/emotional support SMD 0.87 (95% CrI 0.20 to 1.55), graded activity SMD 0.51 (95% CrI 0.14 to 0.93), multimodal SMD 0.52 (95% CrI 0.14 to 0.92)] and psychological outcomes [(1) anxiety CBTHI SMD 0.52 (95% CrI 0.06 to 0.96); (2) depression CBTHI SMD 0.80 (95% CrI 0.26 to 1.38); and (3) emotional distress other psychotherapy SMD 0.58 (95% CrI 0.05 to 1.13), relaxation/stretching/social support/emotional support SMD 0.66 (95% CrI 0.18 to 1.28) and sport/exercise SMD 0.49 (95% CrI 0.03 to 1.01)]. At short-term follow-up, behavioural interventions showed some beneficial effects for specific physical symptoms [(1) pain: CBTHI SMD 0.73 (95% CrI 0.10 to 1.39); (2) fatigue: CBTLI SMD 0.62 (95% CrI 0.11 to 1.14), relaxation/stretching/social support/emotional support SMD 0.51 (95% CrI 0.06 to 1.00)] and psychological outcomes [(1) anxiety: CBTHI SMD 0.74 (95% CrI 0.14 to 1.34); (2) depression: CBTHI SMD 0.93 (95% CrI 0.37 to 1.52); and (3) emotional distress: relaxation/stretching/social support/emotional support SMD 0.82 (95% CrI 0.02 to 1.65), multimodal SMD 0.43 (95% CrI 0.04 to 0.91)]. For physical functioning, only multimodal therapy showed beneficial effects: end-of-treatment SMD 0.33 (95% CrI 0.09 to 0.59); and short-term follow-up SMD 0.78 (95% CrI 0.23 to 1.40). For impact on daily activities, CBTHI was the only behavioural intervention to show beneficial effects [end-of-treatment SMD 1.30 (95% CrI 0.59 to 2.00); and short-term follow-up SMD 2.25 (95% CrI 1.34 to 3.16)]. Few effects remained at long-term follow-up. General practitioner interventions showed no significant beneficial effects for any outcome. No intervention group showed conclusive beneficial effects for measures of symptom load (somatisation). A large degree of heterogeneity was found across individual studies in the assessment of cost-effectiveness. Several studies suggested that the interventions produce fewer quality-adjusted life-years than usual care. For those interventions that generated quality-adjusted life-year gains, the mid-point incremental cost-effectiveness ratios (ICERs) ranged from £1397 to £129,267, but, where the mid-point ICER fell below £30,000, the exploratory assessment of uncertainty suggested that it may be above £30,000.

LIMITATIONS

Sparse networks meant that it was not possible to conduct a metaregression to explain between-study differences in effects. Results were not consistent within intervention type, and there were considerable differences in characteristics between studies of the same type. There were moderate to high levels of statistical heterogeneity. Separate analyses were conducted for three time points and, therefore, analyses are not repeated-measures analyses and do not account for correlations between time points.

CONCLUSIONS

Behavioural interventions showed some beneficial effects for specific medically unexplained symptoms, but no one behavioural intervention was effective across all medically unexplained symptoms. There was little evidence that these interventions are effective for measures of symptom load (somatisation). General practitioner-led interventions were not shown to be effective. Considerable heterogeneity in interventions, populations and sparse networks mean that results should be interpreted with caution. The relationship between patient and service provider is perceived to play a key role in facilitating a successful intervention. Future research should focus on testing the therapeutic effects of the general practitioner-patient relationship within trials of behavioural interventions, and explaining the observed between-study differences in effects within the same intervention type (e.g. with more detailed reporting of defined mechanisms of the interventions under study).

Myalgic encephalomyelitis/chronic fatigue syndrome and the biopsychosocial model: a review of patient harm and distress in the medical encounter

Objective: Despite the growing evidence of physiological and cellular abnormalities in myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS), there has been a strong impetus to tackle the illness utilizing a biopsychosocial model. However, many sufferers of this disabling condition report distress and dissatisfaction following medical encounters. This review seeks to account for this discord.Methods: A narrative review methodology is employed to synthesize the evidence for potential iatrogenesis.Results: We identify seven potential modalities of iatrogenesis or harm reported by patients:difficulties in reaching an acceptable diagnosis;misdiagnosis, including of other medical and psychological conditions;difficulties in accessing the sick role, medical care and social support;high levels of patient dissatisfaction with the quality of medical care;negative responses to controversial therapies (cognitive behavioral therapy and graded exercise therapy);challenges to the patient narrative and experience;psychological harm (individual and collective distress).Conclusion: The biopsychosocial framework currently applied to ME/CFS is too narrow in focus and fails to adequately incorporate the patient narrative. Misdiagnosis, conflict, and harm are observable outcomes where doctors' and patients' perspectives remain incongruent. Biopsychosocial practices should be scrutinized for potential harms. Clinicians should consider adopting alternative patient-centred approaches.Implications for rehabilitationPatients with ME/CFS may report or experience one or more of the modalities of harms and distress identified in this review.It is important health and rehabilitation professionals seek to avoid and minimize harms when treating or assisting ME/CFS patients.There are conflicting models of ME/CFS; we highlight two divergent models, a biopsychosocial model and a biomedical model that is preferred by patients.The 'biopsychosocial framework' applied in clinical practice promotes treatments such as cognitive behavioral therapy and exercise therapy, however, the evidence for their success is contested and many patients reject the notion their illness is perpetuated by dysfunctional beliefs, personality traits, or behaviors.Health professionals may avoid conflict and harm causation in ME/CFS by adopting more concordant 'patient-centred' approaches that give greater prominence to the patient narrative and experience of illness.

Epistemic injustice in healthcare encounters: evidence from chronic fatigue syndrome

Chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) remains a controversial illness category. This paper surveys the state of knowledge and attitudes about this illness and proposes that epistemic concerns about the testimonial credibility of patients can be articulated using Miranda Fricker's concept of epistemic injustice. While there is consensus within mainstream medical guidelines that there is no known cause of CFS/ME, there is continued debate about how best to conceive of CFS/ME, including disagreement about how to interpret clinical studies of treatments. Against this background, robust qualitative and quantitative research from a range of countries has found that many doctors (and medical students) display uncertainty about whether CFS/ME is real, which may result in delays in diagnosis and treatment for patients. Strikingly, qualitative research evinces that patients with CFS/ME often experience suspicion by healthcare professionals, and many patients vocally oppose the effectiveness, and the conceptualisation, of their illness as psychologically treatable. We address the intersection of these issues and healthcare ethics, and claim that this state of affairs can be explained as a case of epistemic injustice (2007). We find evidence that healthcare consultations are fora where patients with CFS/ME may be particularly vulnerable to epistemic injustice. We argue that the (often unintentional) marginalisation of many patients is a professional failure that may lead to further ethical and practical consequences both for progressive research into CFS/ME, and for ethical care and delivery of current treatments among individuals suffering from this debilitating illness.

An ‘Overwhelming Illness’

The processes through which people learn to live with CFS/ME are poorly understood and have not been rigorously explored within the literature. Semi-structured interviews were conducted with eight women and analysed using interpretative phenomenological analysis. Participants initially described being ‘overwhelmed’ by CFS/ME. Attempts at seeking help were unsatisfactory and participants described feeling let down and disbelieved. Participants reacted to this by identifying types of ‘self-help’ and assertively taking more responsibility for their illness and its treatment. Acquiring social support and greater knowledge were key mediating factors in the emergence of control and acceptance. The relevance of the themes to existing research and the implications for clinical practice are considered.

Overcoming the barriers to the diagnosis and management of chronic fatigue syndrome/ME in primary care: a meta synthesis of qualitative studies

BACKGROUND

The NICE guideline for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) emphasises the need for an early diagnosis in primary care with management tailored to patient needs. However, GPs can be reluctant to make a diagnosis and are unsure how to manage people with the condition.

METHODS

A meta synthesis of published qualitative studies was conducted, producing a multi-perspective description of barriers to the diagnosis and management of CFS/ME, and the ways that some health professionals have been able to overcome them. Analysis provided second-order interpretation of the original findings and developed third-order constructs to provide recommendations for the medical curriculum.

RESULTS

Twenty one qualitative studies were identified. The literature shows that for over 20 years health professionals have reported a limited understanding of CFS/ME. Working within the framework of the biomedical model has also led some GPs to be sceptical about the existence of the condition. GPs who provide a diagnosis tend to have a broader, multifactorial, model of the condition and more positive attitudes towards CFS/ME. These GPs collaborate with patients to reach agreement on symptom management, and use their therapeutic skills to promote self care.

CONCLUSIONS

In order to address barriers to the diagnosis and management of CFS/ME in primary care, the limitations of the biomedical model needs to be recognised. A more flexible bio-psychosocial approach is recommended where medical school training aims to equip practitioners with the skills needed to understand, support and manage patients and provide a pathway to refer for specialist input.

Understanding medical students' views of chronic fatigue syndrome: a qualitative study

Chronic fatigue syndrome receives little attention in the medical curriculum. This study explores UK medical students' knowledge of and attitudes towards chronic fatigue syndrome. Semi-structured interviews (average length 22 minutes) were conducted with 21 participants (7 females and 14 males) in years 3 (n = 4), 4 (n = 11) and 5 (n = 6) of their studies. Inductive thematic analysis taking a realist perspective produced three themes: limited knowledge, influences on attitudes and training needs. Students acquired their knowledge and attitudes largely from informal sources and expressed difficulty understanding chronic fatigue syndrome within a traditional biomedical framework. Incorporating teaching about chronic fatigue syndrome into the medical curriculum within the context of a biopsychosocial understanding of illness could encourage more positive attitudes towards chronic fatigue syndrome.

Fatigue Scales and Chronic Fatigue Syndrome: Issues of Sensitivity and Specificity

Few studies have explored issues of sensitivity and specificity for using the fatigue construct to identify patients meeting chronic fatigue syndrome (CFS) criteria. In this article, we examine the sensitivity and specificity of several fatigue scales that have attempted to define severe fatigue within CFS. Using Receiver Operating Characteristic (ROC) curve analysis, we found most scales and sub-scales had either significant specificity and/or sensitivity problems. However, the post-exertional subscale of the ME/CFS Fatigue Types Questionnaire (Jason, Jessen, et al., 2009) was the most promising in terms of specificity and sensitivity. Among the more traditional fatigue scales, Krupp, LaRocca, Muir-Nash, and Steinberg's (1989) Fatigue Severity Scale had the best ability to differentiate CFS from healthy controls. Selecting questions, scales and cut off points to measure fatigue must be done with extreme care in order to successfully identify CFS cases.

Making the diagnosis of Chronic Fatigue Syndrome/Myalgic Encephalitis in primary care: a qualitative study

Background

NICE guidelines emphasise the role of the primary care team in the management of patients with Chronic Fatigue Syndrome/Myalgic Encephalitis (CFS/ME). A key stage in effective management is making an accurate early diagnosis, supported by appropriate referral.

Methods

A nested qualitative study within a multi-centre randomised controlled trial which aimed to explore GPs' views on their role in making the diagnosis of CFS/ME and subsequent management of patients in primary care. Semi-structured interviews with 22 GPs. Interviews were transcribed verbatim and an iterative approach used to develop themes from the dataset.

Results

GPs described difficulties in defining CFS/ME and suggested that their role in making a diagnosis was to exclude physical causes for the patient's symptoms, but they reported little confidence in positively attributing the label of CFS/ME to a patient and their symptoms. GPs suggested that the label of CFS/ME could be potentially harmful for the patient. The role of referral to secondary care was debated and GPs struggled defining their own role in management of this group of patients.

Conclusions

Until GPs feel comfortable making the diagnosis of CFS/ME and facilitating initial management, and have appropriate services to refer patients to, there will continue to be delays in confirming the diagnosis and patients presenting in primary care with fatigue may not receive appropriate care.

Cognitive behavioural therapy and psycho-education for chronic fatigue syndrome in young people: reflections from the families' perspective

OBJECTIVES

Recent trials have produced optimistic results for family-focussed cognitive behavioural therapy (CBT) for chronic fatigue syndrome (CFS) in young people. This study sought to examine the under-researched question of the views and experiences of patients and families who take part.

DESIGN

Semi-structured interviews and qualitative analysis were chosen in order to address clients' perspectives in depth.

METHODS

Sixteen young people and sixteen parents who participated in a trial of CBT versus psycho-education (PE) for CFS were interviewed. Key themes were discerned using inductive thematic analysis.

RESULTS

Most families had low expectations of a cure but hope for improvement. Generally speaking, participants found both CBT and PE acceptable and helpful. Behavioural aspects of CBT (e.g. goal-setting, graded activity) were found helpful. The opportunity to gain support, recognition and validation was important. Cognitive elements of therapy were sometimes deemed inappropriate and some felt emotional aspects of CFS were not adequately addressed. Participants were ambivalent towards the extent of family involvement. Negative experiences related to the therapy setting and feeling inappropriately labeled. Most participants felt therapy was a stepping-stone towards normal life, although many felt recovery was incomplete. Very few differences were found between themes from CBT and PE participants. A notable exception was that every young person who experienced CBT described therapy as helpful, whereas the participants who strongly opposed the therapy approach had all experienced PE.

CONCLUSIONS

The detailed insights regarding families' therapy experiences suggest areas of improvement for service delivery and topics for further investigation.

Practice Nurses' views of their role in the management of Chronic Fatigue Syndrome/Myalagic Encephalitis: a qualitative study

Background

NICE guidelines suggest that patients with Chronic Fatigue Syndrome/Myalgic Encephalitis (CFS/ME) should be managed in Primary Care. Practice Nurses are increasingly being involved in the management of long-term conditions, so are likely to also have a growing role in managing CFS/ME. However their attitudes to, and experiences of patients with CFS/ME and its management must be explored to understand what barriers may exist in developing their role for this group of patients. The aim of this study was to explore Practice Nurses' understanding and beliefs about CFS/ME and its management.

Methods

Semi-structured interviews with 29 Practice Nurses. Interviews were transcribed verbatim and an iterative approach used to develop themes from the dataset.

Results

Practice nurses had limited understanding about CFS/ME which had been largely gained through contact with patients, friends, personal experiences and the media rather than formal training. They had difficulty seeing CFS/ME as a long term condition. They did identify a potential role they could have in management of CFS/ME but devalued their own skills in psychological intervention, and suggested counselling would be an appropriate therapeutic option. They recognised a need for further training and on going supervision from both medical and psychological colleagues. Some viewed the condition as contentious and held pejorative views about CFS/ME. Such scepticism and negative attitudes will be a significant barrier to the management of patients with CFS/ME in primary care.

Conclusion

The current role of Practice Nurses in the ongoing management of patients with CFS/ME is limited. Practice Nurses have little understanding of the evidence-base for treatment of CFS/ME, particularly psychological therapies, describing management options in terms of advice giving, self-help or counselling. Practice Nurses largely welcomed the potential development of their role in this area, but identified barriers and training needs which must be addressed to enable them to feel confident managing of patients with this condition. Training must begin by addressing negative attitudes to patients with CFS/ME.

Identity and coping experiences in Chronic Fatigue Syndrome: a synthesis of qualitative studies

OBJECTIVE

To provide insight into patients' and doctors' experiences with CFS.

METHODS

We compiled available qualitative studies and applied meta-ethnography to identify and translate across the studies. Analysis provided second-order interpretation of the original findings and developed third-order constructs from a line of arguments.

RESULTS

Twenty qualitative studies on CFS experiences were identified. Symptom experiences and the responses from significant others could jeopardise the patients' senses of identity. They felt severely ill, yet blamed and dismissed. Patients' beliefs and causal attributions oppose the doctor's understanding of the condition. For the patient, getting a diagnosis and knowing more was necessary for recovery. Doctors were reluctant towards the diagnosis, and struggle to maintain professional authority. For patients, experience of discreditation could lead to withdrawal and behavioural disengagement.

CONCLUSION

The identities of CFS patients are challenged when the legitimacy of their illness is questioned. This significant burden adds to a loss of previously established identity and makes the patient more vulnerable than just suffering from the symptoms. CFS patients work hard to cope with their condition by knowing more, keeping a distance to protect themselves and learning more about their limits.

PRACTICE IMPLICATIONS

Doctors can support patients' coping by supporting the strong sides of the patients instead of casting doubt upon them.

Complementary and alternative medical therapy utilization by people with chronic fatiguing illnesses in the United States

BACKGROUND

Chronic fatiguing illnesses, including chronic fatigue syndrome (CFS), pose a diagnostic and therapeutic challenge. Previous clinical reports addressed the utilization of health care provided to patients with CFS by a variety of practitioners with other than allopathic training, but did not examine the spectrum of complementary and alternative medicine (CAM) therapies used. This study was designed to measure CAM therapy use by persons with fatiguing illnesses in the United States population.

METHODS

During a random-digit dialing survey to estimate the prevalence of CFS-like illness in urban and rural populations from different geographic regions of the United States, we queried the utilization of CAM including manipulation or body-based therapies, alternative medical systems, mind-body, biologically-based, and energy modalities.

RESULTS

Four hundred forty fatigued and 444 non-fatigued persons from 2,728 households completed screening. Fatigued subjects included 53 persons with prolonged fatigue, 338 with chronic fatigue, and 49 with CFS-like illness. Mind-body therapy (primarily personal prayer and prayer by others) was the most frequently used CAM across all groups. Among women, there was a significant trend of increasing overall CAM use across all subgroups (p-trend = 0.003). All categories of CAM use were associated with significantly poorer physical health scores, and all but one (alternative medicine systems) were associated with significantly poorer mental health scores. People with CFS-like illness were significantly more likely to use body-based therapy (chiropractic and massage) than non-fatigued participants (OR = 2.52, CI = 1.32, 4.82). Use of body-based therapies increased significantly in a linear trend across subgroups of non-fatigued, prolonged fatigued, chronic fatigued, and CFS-like subjects (p-trend = 0.002). People with chronic fatigue were also significantly more likely to use body-based therapy (OR = 1.52, CI = 1.07, 2.16) and mind-body (excluding prayer) therapy than non-fatigued participants (OR = 1.73, CI = 1.20 - 2.48).

CONCLUSION

Utilization of CAM was common in fatiguing illnesses, and was largely accounted for by the presence of underlying conditions and poor physical and mental health. Compared to non-fatigued persons, those with CFS-like illness or chronic fatigue were most likely to use body-based and mind-body therapies. These observations have important implications for provider education programs and development of intervention strategies for CFS.

General practitioners' perceptions of chronic fatigue syndrome and beliefs about its management, compared with irritable bowel syndrome: qualitative study

OBJECTIVES

To compare general practitioners' perceptions of chronic fatigue syndrome and irritable bowel syndrome and to consider the implications of their perceptions for treatment.

DESIGN

Qualitative analysis of transcripts of group discussions.

PARTICIPANTS AND SETTING

A randomly selected sample of 46 general practitioners in England.

RESULTS

The participants tended to stereotype patients with chronic fatigue syndrome as having certain undesirable traits. This stereotyping was due to the lack of a precise bodily location; the reclassification of the syndrome over time; transgression of social roles, with patients seen as failing to conform to the work ethic and "sick role" and conflict between doctor and patient over causes and management. These factors led to difficulties for many general practitioners in managing patients with chronic fatigue syndrome. For both conditions many participants would not consider referral for mental health interventions, even though the doctors recognised social and psychological factors, because they were not familiar with the interventions or thought them unavailable or unnecessary.

CONCLUSIONS

Barriers to the effective clinical management of patients with irritable bowel syndrome and chronic fatigue syndrome are partly due to doctors' beliefs, which result in negative stereotyping of patients with chronic fatigue syndrome and the use of management strategies for both syndromes that may not take into account the best available evidence.

Medication use by persons with chronic fatigue syndrome: results of a randomized telephone survey in Wichita, Kansas

BACKGROUND

Chronic fatigue syndrome (CFS) is characterized by profound fatigue, which substantially interferes with daily activities, and a characteristic symptom complex. Patients use a variety of prescribed and self-administered medications, vitamins, and supplements for relief of their symptoms. The objective of this study was to describe utilization of medications and supplements by persons with CFS and non-fatigued individuals representative of the general population of Wichita, Kansas.

METHODS

We used a random-digit dialing telephone survey to identify persons with CFS in the general population of Wichita, Kansas. Subjects who on the basis of telephone interview met the CFS case definition, and randomly selected non-fatigued controls, were invited for a clinic evaluation that included self-reported use of medications and supplements. Sex-adjusted odds ratios and 95% confidence interval were estimated to measure the association between CFS and use of various drug categories.

RESULTS

We clinically evaluated and classified 90 subjects as CFS during the study and also collected clinical data on 63 who never described fatigue. Subjects with CFS reported using 316 different drugs compared to 157 reported by non-fatigued controls. CFS subjects were more likely to use any drug category than controls (p = 0.0009). Pain relievers and vitamins/supplements were the two most common agents listed by both groups. In addition CFS persons were more likely to use pain relievers, hormones, antidepressants, benzodiazepines, gastro-intestinal, and central nervous system medications (Sex-adjusted odds ratios range = 2.97 - 12.78).

CONCLUSION

Although the reasons for increased use of these agents were not elucidated, the data indicated the CFS patients' need for symptom relief.

Chronic fatigue syndrome: probable pathogenesis and possible treatments

Chronic fatigue syndrome (CFS) belongs in the medically unexplained illnesses. It affects approximately 0.2-0.7% of the population in Western countries. It is characterised by unexplained fatigue, lasting 6 months or more, impairment of neurocognitive functions and quality of sleep, and of somatic symptoms, such as recurrent sore throat, muscle aches, arthralgias, headache and postexertional malaise. No link between infections and CFS has been clearly established but the immune system is activated, there are aberrations in several hypothalamic-pituitary axes and involvement of other parts of the central nervous system. No specific treatment has been found. Cognitive behavioural therapy is established to be of value to improve quality of life. More effective treatment should result, as advances in biomedical as well as psychological research continue.

Illness experience, depression, and anxiety in chronic fatigue syndrome

OBJECTIVE

Given the high rate of psychiatric comorbidity with chronic fatigue syndrome (CFS), we considered two possible correlates of anxiety and depression: lack of illness legitimization and beliefs about limiting physical activity.

METHOD

A total of 105 people diagnosed with CFS reported on their experiences with medical professionals and their beliefs about recovery and completed the depression and anxiety subscales of the Brief Symptom Inventory.

RESULTS

Those who said that their physician did not legitimize their illness (36%) had higher depression and anxiety scores (P's<.05) than their counterparts. Those who believed that limiting their physical exertion was the path to recovery (55%) had lower depression and anxiety scores (P's<.01) than their counterparts.

CONCLUSION

Lack of illness legitimization ranked high as a source of dissatisfaction for CFS patients, and it may aggravate psychiatric morbidity. Many CFS patients believed that staying within what they felt to be their physical limits would improve their condition. This belief, and possibly an accompanying sense of control over their symptoms, may alleviate psychiatric morbidity.

Caring for a relative with chronic fatigue syndrome: difficulties, cognition and acceptance over time

The present study explored the difficulties experienced by carers of chronic fatigue syndrome (CFS) sufferers, their cognitions, and their efforts to accept the illness. Semi-structured interviews were conducted with 17 carers to study these issues, retrospectively, over three stages: before the diagnosis of CFS, shortly after the diagnosis, and at present. Surprisingly, the results suggested that carers, several of them absent from home during the day, felt that their lives were only minimally constrained by the illness. Nevertheless, all carers reported specific coping efforts to manage both the illness and their own distress, and indicated that they learned to accept the illness over time. However, acceptance appeared to be a form of resignation rather than a positive appreciation of the illness. In light of the uncertainties surrounding the origin of CFS and carers' apparent confusion, the results obtained in the present study are significant in that they increase our understanding of CFS carers' quality of life, their efforts to cope with the illness, and the physical and emotional help they may provide to the sufferer. Such information can be usefully employed in the increasing development of counselling interventions and instrumental support networks that involve both sufferers and their carers.

Women's experiences of stigma in relation to chronic fatigue syndrome and fibromyalgia

Chronic fatigue syndrome and fibromyalgia are characterized by being difficult to diagnose and having an elusive etiology and no clear-cut treatment strategy. The question of whether these illnesses are stigmatizing was investigated through interviews with 25 women with these illnesses. The women experienced stigmatization primarily before receiving a diagnosis, and the diffuse symptomatology associated with the illnesses were significant for stigmatization. Stigma consisted of questioning the veracity, morality, and accuracy of patient symptom descriptions and of psychologizing symptoms. Coping with stigma was also explored and found to comprise both withdrawal and approach strategies, depending on the individual's circumstances and goals.

Patients’ perceptions of medical care in chronic fatigue syndrome

This study investigated perceptions of medical care among patients with chronic fatigue syndrome (CFS) referred to a specialist clinic. Sixty-eight patients completed a questionnaire survey on their overall satisfaction with medical care received since the onset of their illness, and their views on specific aspects of care. Two-thirds of patients were dissatisfied with the quality of medical care received. Dissatisfied patients were significantly more likely to describe delay, dispute or confusion over diagnosis; to have received and rejected a psychiatric diagnosis; to perceive doctors as dismissive, skeptical or not knowledgeable about CFS and to feel that the advice given was inadequate or conflicting. Satisfied patients were significantly more likely to perceive doctors as caring, supportive and interested in their illness; to state that they did not expect their doctors to cure CFS and to perceive their GP or hospital doctor as the source of greatest help during their illness. Many patients were critical of the paucity of treatment, but this was not associated with overall satisfaction. The findings suggest that medical care was evaluated less on the ability of doctors to treat CFS, and more on their interpersonal and informational skills. Dissatisfaction with these factors is likely to impede the development of a therapeutic doctor-patient alliance, which is central to the effective management of CFS. The findings suggest a need for better communication and better education of doctors in the diagnosis and management of CFS.

Coping and illness cognitions: chronic fatigue syndrome

The chronic fatigue syndrome (CFS) is described, and research on coping with this illness reviewed and analysed. CFS is a severely disabling illness of unknown etiology, which has occurred in epidemic forms all over the world. However, the number of sufferers has dramatically increased over previous years. The heterogeneous symptomatology of CFS was reviewed, and diagnostic criteria were discussed. The difficulty in establishing causality was emphasized. An interaction of factors appears most likely to be associated with illness onset and maintenance. As the mediating factor could be sufferers' coping behavior, the existing coping literature was reviewed. There might be an association between coping and physical and psychological well-being. Finally, recommendations are made for longitudinal research on coping and coping effectiveness, and for the development of therapeutic interventions.

Diagnosis of psychiatric disorder in clinical evaluation of chronic fatigue syndrome

The overlap of symptoms in chronic fatigue syndrome (CFS) and psychiatric disorders such as depression can complicate diagnosis. Patients often complain that they are wrongly given a psychiatric label. We compared psychiatric diagnoses made by general practitioners and hospital doctors with diagnoses established according to research diagnostic criteria. 68 CFS patients referred to a hospital fatigue clinic were assessed, and psychiatric diagnoses were established by use of a standardized interview schedule designed to provide current and lifetime diagnoses. These were compared with psychiatric diagnoses previously given to patients. Of the 31 patients who had previously received a psychiatric diagnosis 21 (68%) had been misdiagnosed: in most cases there was no evidence of any past or current psychiatric disorder. Of the 37 patients who had not previously received a psychiatric diagnosis 13 (35%) had a treatable psychiatric disorder in addition to CFS. These findings highlight the difficulties of routine clinical evaluation of psychiatric disorder in CFS patients. We advise doctors to focus on subtle features that discriminate between disorders and to use a brief screening instrument such as the Hospital Anxiety and Depression Scale.

Use of alternative treatments by chronic fatigue syndrome discordant twins

Background: Patients with chronic fatigue syndrome (CFS) have been faced with difficulties in diagnosis and lack of effective treatments. Anecdotal evidence suggests that use of alternative treatments may be common in these patients. Our primary objective was to compare the prevalence and patterns of alternative medicine use among twins who met the Centers for Disease Control and Prevention (CDC) CFS criteria to that of their non-CFS co-twins. Secondary goals were to assess how often alternative medicine use was discussed with physicians and the perceived benefit of these therapies. Methods: Sixty-three twin pairs discordant for CFS completed a survey about their use of 22 alternative therapies. Matched pair odds ratios and 95% confidence intervals were used to examine differences in the use between CFS twins and their non-CFS co-twins. Results: 91% of twins with CFS and 71% of non-CFS twins had used at least 1 alternative treatment in their lifetime. Twins with CFS were more likely to use homeopathy, mega-vitamins, herbal therapies, biofeedback, relaxation/meditation, guided imagery, massage therapy, energy healing, religious healing by others, and self-help groups than their non-CFS counterparts. A large proportion of all twins found alternative therapies helpful; however, only 42% of those with CFS and 23% of those without CFS discussed their use of alternative medicine with a physician. Conclusions: Individuals with CFS frequently used alternative medical treatments yet rarely communicated this use to their medical doctor. Future research should ascertain the usefulness of alternative practices in the management of CFS.

Use of formal and informal care among people with prolonged fatigue: a review of the literature

Prolonged fatigue is a common symptom in the community and a common complaint in GPs' surgeries. The current consensus is that prolonged fatigue is most appropriately managed within primary care but that quality of care is patchy. Diagnosis is difficult and there is no conclusive evidence about effective treatment. This can lead to confusion and controversy among lay people and health professionals alike. Although the value of a positive doctor-patient relationship is emphasized, general practice consultations are frequently experienced as difficult by both parties. Moreover, little is known about how people access other sources of care and information about prolonged fatigue, such as alternative medicine, self-help groups, lay others, and self care, in conjunction with or as an alternative to care from health professionals. This paper reviews the literature on the nature and extent of the problem prolonged fatigue represents for primary care, and on the use of formal and informal care for prolonged fatigue.
