Chronic fatigue syndrome patients have no reason to accept the PACE trial results: Response to Keith J Petrie and John Weinman

Abstract:

Petrie and Weinman urge chronic fatigue syndrome patients to move on from their beliefs about their illness and accept the findings of the PACE trial. This is unreasonable in view of the failure of PACE to achieve evidence of recovery through cognitive behaviour therapy and graded exercise therapy in either self-reports or the objective measure of the 6-minute walking test. Contrary to their suggestion, the Institute of Medicine describes chronic fatigue syndrome not as psychological but as a serious, chronic, systemic disease, with post-exertional malaise as its main feature which inhibits exercise. Linking debate about PACE with intimidation of researchers is unjustifiable and damaging to patients.

Adult patients’ experiences of NHS specialist services for chronic fatigue syndrome (CFS/ME): a qualitative study in England

Abstract:

BACKGROUND: Few studies have explored patients' experiences of treatment for CFS/ME. This study aims to fill this gap by capturing the perspective of patients who have been treated by NHS specialist CFS/ME services in England.

METHODS: Semi-structured interviews were conducted during the period June-September 2014 with 16 adults who were completing treatment at one of three outpatient NHS specialist CFS/ME services. Interviews were analysed thematically using constant comparison techniques, with particular attention paid to contrasting views.

RESULTS: Three themes were identified: 'Journey to specialist services'; 'Things that help or hinder treatment'; and 'Support systems'. Within these themes nine sub-themes were identified. A wide range of factors was evident in forming participants' experiences, including personal characteristics such as perseverance and optimism, and service factors such as flexibility and positive, supportive relationships with clinicians. Participants described how specialist services played a unique role, which was related to the contested nature of the condition. Many participants had experienced a lack of validation and medical and social support before attending a specialist service. Patients' experiences of life before referral, and the concerns that they expressed about being discharged, highlighted the hardship and obstacles which people living with CFS/ME continue to experience in our society.

CONCLUSIONS: The experiences of CFS/ME patients in our study showed that NHS specialist CFS/ME services played a vital role in patients' journeys towards an improved quality of life. This improvement came about through a process which included validation of patients' experiences, acceptance of change, practical advice and support, and therapeutic outcomes.

PACE investigators’ response is misleading regarding patient survey results

Abstract:

The PACE investigators’ citation of a patient survey might mislead readers into thinking that the experience of people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) supports PACE findings. In fact, patient survey evidence directly contradicts the results of the PACE trial. A review of survey data published between 2001 and 2015 reveals that for most patients, graded exercise therapy leads to worsening of symptoms, cognitive behavioural therapy leads to no change in symptoms, and pacing leads to improvement. The experience of people with ME/CFS as reflected in surveys is a rich source of information, made more compelling by the consistency of results. Consequently, patient survey evidence can be used to inform practice, research and guidelines. Misrepresentation of patient experience must be vigorously challenged, to ensure that patients and health professionals make decisions about therapies based on accurate information.

Children’s experiences of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME): a systematic review and meta-ethnography of qualitative studies

Abstract:

OBJECTIVE: To synthesis the qualitative studies of children’s experiences of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME).

DESIGN: Systematic review and meta-ethnography.

BACKGROUND: CFS/ME is an important disabling illness, with uncertain cause and prognosis. As a result, children with CFS/ME can find themselves living with greater uncertainty and stigma, exacerbating the impact of the condition. There is a growing body of qualitative research in CFS/ME, yet there has been no attempt to systematically synthesis the studies involving children.

METHODS: Studies exploring the experiences of children diagnosed with CFS/ME, published or unpublished, using qualitative methods were eligible. MEDLINE, EMBASE, PsycINFO and CINAHL databases were searched as well as grey literature, reference lists and contacting authors. Quality assessment was done independently using the Critical Appraisal Skills Programme (CASP) checklist. Studies were synthesised using techniques of meta-ethnography.

RESULTS: Ten studies involving 82 children with CFS/ME aged 8-18 were included. Our synthesis describes four third-order constructs within children’s experiences: (1) disruption and loss: physical, social and the self; (2) barriers to coping: suspension in uncertainty, problems with diagnosis and disbelief; (3) facilitators to coping: reducing uncertainty, credible illness narratives, diagnosis and supportive relationships and (4) hope, personal growth and recovery. CFS/ME introduces profound biographical disruption through its effects on children’s ability to socialise, perform school and therefore how they see their future. Unfamiliarity of the condition, problems with diagnosis and felt stigma prevent children from forming a new illness identity. Children adopt coping strategies such as building credible explanations for their illness.

CONCLUSIONS: Physical, social, emotional and self-dimensions of life should be included when treating and measuring outcomes from healthcare in paediatric CFS/ME. There is a need for greater recognition and diagnosis of childhood CFS/ME, specialist advice on activity management and improved communication between health and education providers to help children cope with their condition.

Epistemic injustice in healthcare encounters: evidence from chronic fatigue syndrome

Abstract:

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.

Experiences of general practitioner continuity among women with chronic fatigue syndrome/myalgic encephalomyelitis: a cross-sectional study

Abstract:

BACKGROUND: Continuity of care is important for patients with chronic illness in need of coordinated healthcare services from multiple providers. Little is known about how patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) experience continuity of GP care. This study explores how women with CFS/ME experience GP care across the three dimensions of continuity: informational, management, and relational continuity.

METHODS: This cross-sectional study uses questionnaire data collected from members of The Norwegian ME Association. Descriptive statistics and logistic regressions were used to estimate experiences of continuity, and associations with age, education, self-rated degree of CFS/ME, duration of the GP relation (GP duration), and number of GP visits for CFS/ME-related issues during the previous year (GP frequency).

RESULTS: Almost two-thirds of participants reported positive experiences across all three dimensions of GP continuity of care; 64.4% for informational, 64.1% for management, and 77.2% for relational continuity. Lower educational attainment was associated with more negative experiences of informational continuity (primary school only compared to university educated: odds ratio [OR] 0.12, confidence interval [CI] 0.03-0.49, p = 0.003). Compared to participants aged 40-59 years, those aged 60+ years were significantly less likely to have experienced poor (negative) management continuity (OR 0.25, CI 0.09-0.76, p = 0.014). A GP relationship of three or more years was associated with positive experiences of relational continuity (OR 2.32, CI 1.09-4.95, p = 0.030). Compared to those with moderate CFS/ME, those who graded their CFS/ME as severe or very severe were significantly more likely to have negative experiences of relational continuity (OR 0.38, CI 0.14-0.99, p = 0.047).

CONCLUSIONS: A large proportion of participants experienced all three aspects of continuity of GP care (especially the relational dimension) positively. Informational and management continuity scores were moderately lower. Our results suggest greater emphasis on information giving, feedback, and better coordination of care to be good strategies for practice improvement for this patient group.

Activity Patterns in Response to Symptoms in Patients Being Treated for Chronic Fatigue Syndrome: An Experience Sampling Methodology Study

Abstract:

Objective: Cognitive-behavioral models of chronic fatigue syndrome (CFS) propose that patients respond to symptoms with 2 predominant activity patterns-activity limitation and all-or-nothing behaviors-both of which may contribute to illness persistence. The current study investigated whether activity patterns occurred at the same time as, or followed on from, patient symptom experience and affect.

Method: Twenty-three adults with CFS were recruited from U.K. CFS services. Experience sampling methodology (ESM) was used to assess fluctuations in patient symptom experience, affect, and activity management patterns over 10 assessments per day for a total of 6 days. Assessments were conducted within patients’ daily life and were delivered through an app on touchscreen Android mobile phones. Multilevel model analyses were conducted to examine the role of self-reported patient fatigue, pain, and affect as predictors of change in activity patterns at the same and subsequent assessment.

Results: Current experience of fatigue-related symptoms and pain predicted higher patient activity limitation at the current and subsequent assessments whereas subjective wellness predicted higher all-or-nothing behavior at both times. Current pain predicted less all-or-nothing behavior at the subsequent assessment. In contrast to hypotheses, current positive affect was predictive of current activity limitation whereas current negative affect was predictive of current all-or-nothing behavior. Both activity patterns varied at the momentary level.

Conclusions: Patient symptom experiences appear to be driving patient activity management patterns in line with the cognitive-behavioral model of CFS. ESM offers a useful method for examining multiple interacting variables within the context of patients’ daily life. (PsycINFO Database Record

Treatment expectations influence the outcome of multidisciplinary rehabilitation treatment in patients with CFS

Abstract:

OBJECTIVE: To improve the effectiveness of treatment in patients with chronic fatigue syndrome it is worthwhile studying factors influencing outcomes. The aims of this study were (1) to assess the association of expectancy and credibility on treatment outcomes, and (2) to identify baseline variables associated with treatment expectancy and credibility.

METHODS: 122 patients were included in a randomized controlled trial of whom 60 received cognitive behavioural therapy (CBT) and 62 multidisciplinary rehabilitation treatment (MRT). Expectancy and credibility were measured with the credibility and expectancy questionnaire. Outcomes of treatment, fatigue, and quality of life (QoL), were measured at baseline and post-treatment. Multiple linear regressions were performed to analyse associations.

RESULTS: In explaining fatigue and the physical component of the QoL, the effect of expectancy was significant for MRT, whereas in CBT no such associations were found. The main effect of expectancy on the mental component of QoL was not significant. For credibility, the overall effect on fatigue and the physical component of QoL was not significant. In explaining the mental component of QoL, the interaction between treatment and credibility was significant. However, the effects within each group were not significant. In the regression model with expectancy as dependent variable, only treatment centre appeared significantly associated. In explaining credibility, treatment centre, treatment allocation and depression contributed significantly.

CONCLUSIONS: For clinical practice it seems important to check the expectations of the patient, since expectations influence the outcome after MRT.

A Cross Cultural Comparison of Disability and Symptomatology Associated with CFS

Abstract:

Few studies have compared symptomatology and functional differences experienced by patients with chronic fatigue syndrome (CFS) across cultures. The current study compared patients with CFS from the United States (US) to those from the United Kingdom (UK) across areas of functioning, symptomatology, and illness onset characteristics.

Individuals in each sample met criteria for CFS as defined by Fukuda et al. (1994). These samples were compared on two measures of disability and impairment, the DePaul Symptom Questionnarie (DSQ) and the Medical outcomes study 36-item short-form health survey (SF-36).

Results revealed that the UK sample was significantly more impaired in terms of mental health and role emotional functioning, as well as specific symptoms of pain, neurocognitive difficulties, and immune manifestations. In addition, the UK sample was more likely to be working rather than on disability.

Individuals in the US sample reported more difficulties falling asleep, more frequently reported experiencing a sudden illness onset (within 24 hours), and more often reported that the cause of illness was primarily due to physical causes. These findings suggest that there may be important differences in illness characteristics across individuals with CFS in the US and the UK, and this has implications for the comparability of research findings across these two countries.

What matters to children with CFS/ME? A conceptual model as the first stage in developing a PROM

Abstract:

BACKGROUND: Paediatric chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) is relatively common and disabling. Research is hampered because current patient-reported outcome measures (PROMs) do not capture outcomes that are important to children with CFS/ME.

AIM: The aim of this study was to explore the aspects of life and health outcomes that matter to children with CFS/ME.

METHODS: Twenty-five children with CFS/ME were interviewed (11 males, 14 females; mean age 12.9 years (SD 2.2), range 8-17). Twelve were trial participants interviewed during the trial and 13 were recruited as part of a follow-up qualitative study. Parents were present in 19 interviews with their children. Three mothers participated in a focus group. All the interviews and the focus group were audio-recorded and transcribed. Data were analysed thematically using techniques of constant comparison. NVivo was used to structure and categorise data in a systematic way.

RESULTS: Children identified four key themes (health outcome domains): ‘symptoms’ that fluctuated, which caused an unpredictable reduction in both ‘physical activity’ and ‘social participation’ all of which impacted on ’emotional well-being’. These domains were influenced by both ‘management’ and ‘contextual factors’, which could be positive and negative. The relationship between healthcare and school was considered pivotal.

CONCLUSIONS: Children’s descriptions helped to inform a conceptual model that is necessary to develop a new paediatric CFS/ME PROM. Doctors need to be aware of how children conceptualise CFS/ME; the relationship between healthcare and school is fundamental to ameliorate the impact of CFS/ME.
