Contrasting case definitions for chronic fatigue syndrome, Myalgic Encephalomyelitis/chronic fatigue syndrome and myalgic encephalomyelitis

This article uses data from patients recruited using the 1994 case definition of chronic fatigue syndrome (CFS) to contrast those meeting criteria for the Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS) Canadian case definition with those that did not meet these criteria. The study also contrasts those meeting criteria for Myalgic Encephalomyelitis (ME) based on criteria from Ramsay and other theorists with those that did not meet the ME criteria. The ME/CFS case definition criteria identified a subset of patients with more functional impairments and physical, mental, and cognitive problems than the subset not meeting these criteria. The ME subset had more functional impairments, and more severe physical and cognitive symptoms than the subset not meeting ME criteria. When applied to a population meeting the 1994 CFS case definition, both ME/CFS and ME criteria appear to select a more severe subset of patients.     

Quest, chaos and restitution: living with chronic fatigue syndrome/myalgic encephalomyelitis

Chronic illness is disruptive, threatening people's sense of identity and taken for granted assumptions. Transformations in values, expectations and life priorities are likely to be experienced and in order to regain a coherent sense of self, people must interpret their experiences. People with difficult to diagnose illnesses can find themselves living with greater uncertainty and stigma. This paper explores how people with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) describe and interpret their illness experience by applying Arthur Frank's narrative typologies to analyse interviews with 17 British people with CFS/ME. The analysis proposes that a trajectory of narrative typologies is experienced, starting with a restitution narrative, moving to a chaos narrative and, for most, back to a restitution narrative and on to a quest narrative. The presentation of narrative types put forward by people living with CFS/ME differ to those presented by people who are HIV positive and have been treated for breast cancer.

The utility of patient-reported outcome measures among patients with myalgic encephalomyelitis/chronic fatigue syndrome

Purpose

Debilitating fatigue is a core symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS); however, the utility of patient-reported symptom outcome measures of fatigue for ME/CFS patients is problematic due to ceiling effects and issues with reliability and validity. We sought to evaluate the performance of three patient-reported symptom measures in a sample of ME/CFS patients and matched controls.

Methods

Two hundred and forty ME/CFS patients and 88 age, sex, race, and zip code matched controls participated in the study. Participants completed the Multidimensional Fatigue Inventory-20, DePaul Symptom Questionnaire, and RAND SF-36.

Results

The general and physical fatigue subscales on Multidimensional Fatigue Inventory-20, as well as the role of physical health on the RAND SF-36, demonstrated questionable or unacceptable internal consistency and problematic ceiling effects. The DePaul Symptom Questionnaire demonstrated excellent internal reliability, and less than 5 % of participants were at the ceiling on each subscale. The post-exertional malaise subscale on the DePaul Symptom Questionnaire demonstrated excellent clinical utility as it was able to differentiate between ME/CFS patients and controls (OR 1.23, p < .001) and predicted ceiling effects on other patient-reported outcome subscales. A score of 20 on the post-exertional malaise subscale of the DePaul Symptom Questionnaire optimally differentiated between patients and controls.

Conclusions

Significant ceiling effects and concerns with reliability and validity were observed among Multidimensional Fatigue Inventory-20 and RAND SF-36 subscales for ME/CFS patients. The DePaul Symptom Questionnaire addresses a number of concerns typically identified when using patient-reported outcome measures with ME/CFS patients; however, an improved multidimensional patient-reported outcome tool for measuring ME/CFS-related symptoms is warranted.

The adoption of chronic fatigue syndrome/myalgic encephalomyelitis case definitions to assess prevalence: a systematic review

PurposePrevalence estimates have been based on several case definitions of chronic fatigue syndrome (CFS). The purpose of this work is to provide a rigorous overview of their application in prevalence research.MethodsA systematic review of primary studies reporting the prevalence of CFS since 1990 was conducted. Studies were summarized according to study design, prevalence estimates, and case definition used to ascertain cases.ResultsThirty-one studies were retrieved, and eight different case definitions were found. Early estimates of CFS prevalence were based on the 1988 Centers for Disease Control and Prevention, Australian, and Oxford. The 1994 Centers for Disease Control and Prevention, however, has been adopted internationally, as a general standard. Only one study has reported prevalence according to the more recent, Canadian Consensus Criteria. Additional estimates were also found according to definitions by Ho-Yen, the 2005 Centers for Disease Control and Prevention empirical definition, and an epidemiological case definition.ConclusionsAdvances in clinical case definitions during the past 10 years such as the Canadian Consensus Criteria have received little attention in prevalence research. Future assessments of prevalence should consider adopting more recent developments, such as the newly available International Consensus Criteria. This move could improve the surveillance of more specific cases found within CFS.     

HPV vaccination and risk of chronic fatigue syndrome/myalgic encephalomyelitis: A nationwide register-based study from Norway

BackgroundVaccination has been suggested to be involved in the aetiology of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). HPV vaccine was introduced in the Norwegian Childhood Immunisation Programme and offered 12 year old girls from 2009. We studied the association between HPV vaccination and risk of CFS/ME and also assessed medical history in relation to both risk of CFS/ME and HPV vaccine uptake.MethodsIndividual data from national registries, including the Norwegian Population Registry, the Norwegian Patient Registry and the Norwegian Immunisation Registry were linked using the unique personal identification number. Yearly incidence rates of CFS/ME for 2009–2014 were calculated among the 824,133 boys and girls, aged 10–17 living in Norway during these 6 years. A total of 176,453 girls born 1997–2002 were eligible for HPV vaccination and included in further analyses. Hazard ratios (HRs) of CFS/ME were estimated using Cox regression. Risk differences (RDs) of vaccine uptake were estimated with binomial regression.ResultsA similar yearly increase in incidence rate of CFS/ME was observed among girls and boys, IRR = 1.15 (95% confidence interval (CI) 1.10–1.19) and 1.15 (95% CI 1.09–1.22), respectively. HPV vaccination was not associated with CFS/ME, HR = 0.86 (95% CI 0.69–1.08) for the entire follow-up period and 0.96 (95% CI 0.64–1.43) for the first two years after vaccination. The risk of CFS/ME increased with increasing number of previous hospital contacts, HR = 5.23 (95% CI 3.66–7.49) for 7 or more contacts as compared to no contacts. Girls with 7 or more hospital contacts were less likely to be vaccinated than girls with no previous hospital contacts, RD = −5.5% (95% CI −6.7% to −4.2%).ConclusionsNo indication of increased risk of CFS/ME following HPV vaccination was observed among girls in the first 6 birth cohorts offered HPV vaccine through the national immunisation programme in Norway.     

Interventions for the treatment, management and rehabilitation of patients with chronic fatigue syndrome/myalgic encephalomyelitis: an updated systematic review

OBJECTIVES: To determine whether any particular intervention or combination of interventions is effective in the treatment, management and rehabilitation of adults and children with a diagnosis of chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME). DESIGN: Substantive update of a systematic review published in 2002. Randomized (RCTs) and non-randomized controlled trials of any intervention or combination of interventions were eligible for inclusion. Study participants could be adults or children with a diagnosis of CFS/ME based on any criteria. We searched eleven electronic databases, reference lists of articles and reviews, and textbooks on CFS/ME. Additional references were sought by contact with experts. RESULTS: Seventy studies met the inclusion criteria. Studies on behavioural, immunological, pharmacological and complementary therapies, nutritional supplements and miscellaneous other interventions were identified. Graded exercise therapy and cognitive behaviour therapy appeared to reduce symptoms and improve function based on evidence from RCTs. For most other interventions, evidence of effectiveness was inconclusive and some interventions were associated with significant adverse effects. CONCLUSIONS: Over the last five years, there has been a marked increase in the size and quality of the evidence base on interventions for CFS/ME. Some behavioural interventions have shown promising results in reducing the symptoms of CFS/ME and improving physical functioning. There is a need for research to define the characteristics of patients who would benefit from specific interventions and to develop clinically relevant objective outcome measures.     

Quality and acceptability of patient-reported outcome measures used in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME): a systematic review

Purpose  

To review the quality and acceptability of condition-specific, domain-specific and generic multi-item patient-reported outcome measures (PROMs) used in the assessment of adults with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME).     

Accurate diagnosis of myalgic encephalomyelitis and chronic fatigue syndrome based upon objective test methods for characteristic symptoms

Although myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) are considered to be synonymous, the definitional criteria for ME and CFS define two distinct, partially overlapping, clinical entities. ME, whether defined by the original criteria or by the recently proposed criteria, is not equivalent to CFS, let alone a severe variant of incapacitating chronic fatigue. Distinctive features of ME are: muscle weakness and easy muscle fatigability, cognitive impairment, circulatory deficits, a marked variability of the symptoms in presence and severity, but above all, post-exertional “malaise”: a (delayed) prolonged aggravation of symptoms after a minor exertion. In contrast, CFS is primarily defined by (unexplained) chronic fatigue, which should be accompanied by four out of a list of 8 symptoms, e.g., headaches. Due to the subjective nature of several symptoms of ME and CFS, researchers and clinicians have questioned the physiological origin of these symptoms and qualified ME and CFS as functional somatic syndromes. However, various characteristic symptoms, e.g., post-exertional “malaise” and muscle weakness, can be assessed objectively using well-accepted methods, e.g., cardiopulmonary exercise tests and cognitive tests. The objective measures acquired by these methods should be used to accurately diagnose patients, to evaluate the severity and impact of the illness objectively and to assess the positive and negative effects of proposed therapies impartially.     

A definition of recovery in myalgic encephalomyelitis and chronic fatigue syndrome should be based upon objective measures

Introduction

Adamowicz and colleagues recently proposed to use “a consistent definition of recovery that captures a broad-based return to health with assessments of both fatigue and function as well as the patients’ perceptions of his/her recovery status” for patients with chronic fatigue syndrome (CFS).

Methods

A qualitative analysis of case definitions for Myalgic encephalomyelitis (ME) and CFS and methods to assess the symptoms and clinical status of ME and CFS patients objectively.

Results

The criteria of CFS define a heterogeneous disorder. ME, often used interchangeably with CFS, is principally defined by muscle weakness, cognitive impairment etc., but above all post-exertional “malaise”: a long-lasting increase in symptoms, e.g. muscle pain and cognitive deficits, after a minor exertion. The principle symptom of CFS however is “chronic fatigue”. Since post-exertional “malaise” is not obligatory for CFS, only part of the CFS patients meet the diagnostic criteria for ME, while not all ME patients qualify as CFS patients. There are several accepted methods to assess characteristic symptoms and the clinical status of ME and CFS patients using objective measures, e.g. (repeated) cardiopulmonary exercise tests.

Conclusion

To resolve the debate about the clinical status, proposed effectiveness of therapies and recovery in ME and CFS, it is crucial to accurately diagnose patients using well-defined criteria for ME and CFS and an objective assessment of various typical symptoms, since subjective measures such as “fatigue” will perpetuate the debate.     

Meeting the health needs of older people with intellectual disabilities: exploring the experiences of residential social care staff

Older people with intellectual disabilities often experience high levels of health needs and multiple morbidities but they may be supported by residential care staff with little or no previous experience of identifying and meeting health needs. Little is known regarding how they undertake this health‐related role and this exploratory study seeks to address this gap. A purposive sample of 14 managers of supported living accommodation in Wales were interviewed in 2014 to determine their experiences of supporting tenants in relation to age‐related health needs. The semi‐structured interviews were transcribed and thematically analysed. Three of the emerging themes are reported in this paper: meeting health needs, the consequences of ageing and relationships. Findings indicate that residential care staff support older people with intellectual disabilities with complex and multiple health needs: they monitor health status, support access to healthcare, provide additional support arising from changing health needs and advocate for tenants in the context of healthcare. However, their role is often not understood by healthcare professionals. The importance of staff having a long‐term relationship with those they support was identified as being important to identifying any health‐related changes. The need to develop effective relationships with healthcare staff was also noted. It is concluded that there is a need for better understanding among health staff of the role of residential social care workers and for further research regarding health‐related communication.     

Mothers experiencing homelessness: mental health, support and social care needs

Little is known about the experiences of mothers who become homeless. The numbers of women with children in this situation are growing, most becoming homeless following domestic or neighbour abuse, or the breakdown of family relationships. This qualitative study aimed to describe mothers' experiences of homelessness in relation to their mental health, support and social care needs. Twenty-eight homeless women with dependent children residing in hostels were interviewed. The experience of homelessness was stressful, but viewed as a respite for many of the participants because they had experienced violence and harassment prior to their stay in the hostels. Many described poor mental health, which they related to the conditions in hostels and traumas that they had experienced before becoming homeless. Their experiences and perceptions of the services available were mixed. Some valued the support offered by staff and other residents, but the majority felt that there was a lack of resources to address their needs. Many women had difficulty coping with homelessness, and several said that support from other homeless women was an important source of help. Services need to work together to meet the multiple health, social, psychological and housing needs of these women.     

Implementing cognitive behavior therapy for chronic fatigue syndrome in mental health care: a costs and outcomes analysis

Background  

This study investigated the costs and outcomes of implementing cognitive behavior therapy (CBT) for chronic fatigue syndrome (CFS) in a mental health center (MHC). CBT is an evidence-based treatment for CFS that was scarcely available until now. To investigate the possibilities for wider implementation, a pilot implementation project was set up.     

‘Betwixt and between’; liminality in recovery stories from people with myalgic encephalomyelitis (ME) or chronic fatigue syndrome (CFS)

This paper explores experiences of 16 people claiming to have recovered from Myalgic Encephalomyelitis (ME) or Chronic Fatigue Syndrome (CFS) using the concept of liminality. Liminality describes the status of those falling between socially recognised and medically sanctioned categories, and illuminates both the experience of illness and the process of recovery from ME/CFS. The liminality experienced during illness was akin to that described by Turner with a degree of communitas among sufferers. As recovery progressed, participants stressed the percentage to which they had improved, and compared themselves with peers and themselves prior to the illness. Recovery did not mean transition into a post‐liminal phase, but involved a new liminality, characterised by straddling boundaries between illness and wellness. Participants continued strategies such as rest, pacing and meditation. This second liminal state included difficulty in communicating the experience convincingly, and estrangement from the ME/CFS community. Thus, recoverees moved from the liminality of illness to a second, and less legible state of sustained liminality in recovery, described as having one foot in the ill world, one foot in the well world. This suggests that more needs to be understood about the recovery experience to assist those making the transition toward wellness.     

Collaboration between social workers and dentists for care of people with special health needs (a commentary)

The difficulties faced by individuals with mental retardation, developmental and other disabilities in securing dental services are reviewed. The need for social workers to stimulate family members and other health care providers to collaborate with and challenge dental practitioners is emphasized.     

Social networks and social support among black urban elderly: a health care resource

In recent years, there has been a growing interest in social networks and social support among the black urban elderly. This article reports from a community survey on the size, interaction, availability and adequacy of support and roles of kin and non-kin network members. The findings reveal frequent contact among family, relatives, friends, and neighbors. Black elderly utilize network members differentially for emergency and nonemergency situations. Implications for social work in health care are discussed.     

Good practice in social care: the views of people with severe and complex needs and those who support them

This paper reports findings drawn from a study of good practice in English social care for adults with disability and older people with severe and complex needs. People with severe and complex needs are a relatively small proportion of adult social care service users, but they are growing in numbers and have resource‐intensive needs. The study involved qualitative research with adults with disability and older people with severe and complex needs, family carers and members of specialist organisations (n = 67), focusing on the features of social care services they considered to be good practice. Data were collected between August 2010 and June 2011. The approach to data collection was flexible, to accommodate participants' communication needs and preferences, including face‐to‐face and telephone interviews, Talking Mats^© sessions and a focus group. Data were managed using Framework and analysed thematically. Features of good practice were considered at three levels: (i) everyday support; (ii) service organisation; and (iii) commissioning. Findings relating to the first two of these are presented here. Participants emphasised the importance of person‐centred ways of working at all levels. Personalisation, as currently implemented in English social care, aims to shift power from professionals to service users through the allocation of personal budgets. This approach focuses very much on the role of the individual in directing his/her own support arrangements. However, participants in this study also stressed the importance of ongoing professional support, for example, from a specialist key worker or case manager to co‐ordinate diverse services and ensure good practice at an organisational level. The paper argues that, despite the recent move to shift power from professionals to service users, people with the most complex needs still value support from professionals and appropriate organisational support. Without these, they risk being excluded from the benefits that personalisation, properly supported, could yield.
