Work-related impairment and employment-focused rehabilitation options for individuals with chronic fatigue syndrome: A review

A retrospective study of patients presenting with speech and language therapy needs within multidisciplinary Long COVID services: A service evaluation describing and comparing two cohorts across two NHS Trusts

BACKGROUND

Post-COVID Syndrome (also known as Long COVID) refers to the multi-system condition affecting individuals following COVID-19 infection. This can include speech and language therapy (SLT) needs, including voice, swallowing, communication and upper airway difficulties. There is limited published literature in this clinical area of practice, particularly for those receiving input from community SLT services.

AIMS

To describe and compare demand, typical SLT presentation and service delivery across two National Health Service (NHS) Long COVID multidisciplinary services. Independent retrospective service evaluation was completed for each service. Descriptive statistics were produced and compared across services. This service evaluation followed The Strengthening the Reporting of Observation Studies in Epidemiology guidelines for cohort studies.

OUTCOMES & RESULTS

The findings indicated similarities across the two services in SLT service need and demand, clinical presentations and intervention approaches provided within Long COVID services. There were specific differences in the service provision and delivery of intervention in cognitive communication and upper airways subspecialities.

CONCLUSIONS & IMPLICATIONS

This study highlights the clinical complexities of SLT needs in individuals with Long COVID and the importance for an appropriately skilled and supported workforce within effective multidisciplinary teams. We call for consensus on SLT practices and a consistent and standardized approach to evaluation for SLT needs in Long COVID.

WHAT THIS PAPER ADDS

What is already known on this subject SLT needs, including voice, swallowing, communication and upper airway difficulties, are present in individuals presenting with Long COVID, both in those who were or were not hospitalized. SLTs are seeing such individuals in a variety of settings, including community services and Long COVID multidisciplinary teams. There is minimal evidence of the clinical presentations and interventions provided to individuals with SLT needs compared across Long COVID services. What this study adds to existing knowledge This study compares two NHS Long COVID services providing a SLT service pathway. It highlights the similarities and differences in service demand and capacity, patient presentation, and SLT intervention to make suggestions for future practice consideration and priority evaluation. Expert consensus among SLT clinicians is a priority to ensure clinicians are delivering consistent and equitable care for patients, while new evidence and data emerge. A consistent and standardized approach to data collection and outcome measures is essential to ensure future research captures the impact and value of SLT input with individuals with Long COVID. What are the clinical implications of this work? The complexities and multifactorial SLT needs of individual with Long COVID call for appropriate SLT staffing provision, skill and training to fulfil the needs of this population. Speech and language therapists should be integrated with multidisciplinary Long COVID services to provide holistic care for patients and to support the professionals working with individuals with post-COVID voice, swallowing, communication and upper airway symptoms.

Separating Patients with SEID from Those with CFS in the French ME/CFS Association, with Some Thoughts on Nomenclature

In 2015, the American Institute of Medicine, now called the National Academy of Medicine, (IOM/NAM) proposed new diagnostic criteria for both Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and a new label: Systemic Exertion Intolerance Disease (SEID). This study aimed to evaluate the SEID criteria among members of the French Association of ME/CFS (ASFC) and their opinion about this new name. We sent an anonymous questionnaire to 494 ASFC members, using French-translated questions derived from the IOM/NAM tool kit. Among the 178/231 responding subjects who reported ME/CFS diagnosis, 150 (84%) met the criteria of SEID. For each set of questions, we identified some of them that significantly distinguished SEID from non-SEID patients concerning unrefreshing sleep, cognitive disorders, and orthostatic intolerance items. Forty-six percent of the respondents considered the "SEID" terminology as more appropriate than "CFS", 39% considered it inappropriate, and 15% had no opinion. Some questions better identified the SEID criteria. The IOM/NAM SEID criteria captured a large part of ASFC members suffering from ME/CFS. However, this new SEID label was not well accepted by the subjects, nor were the other denominations, suggesting that a better term should be found. Pending development of specific markers, further work with patient communities is needed to find a more suitable label.

Chronic fatigue syndrome and occupational status: a retrospective longitudinal study

BACKGROUND

Few studies into chronic fatigue syndrome (CFS) have emphasized work-related consequences, including return to work after illness.

AIMS

This paper explores socio-demographic, work and clinical characteristics that are associated with occupational status among patients who were assessed at baseline and a follow-up point.

METHODS

Longitudinal data were assessed from patients affected by CFS who attended an outpatient CFS treatment service between 2007 and 2014. Employment status at baseline and follow-up was available for 316 patients. Data were also included on gender, age, duration of CFS, fatigue severity, type and number of treatment sessions, coping strategies, functional impairment, common mental disorders and physical functioning.

RESULTS

Most patients were female (73%) and had been affected by CFS for longer than 2 years (66%). Patients were followed up for an average of 285 days and over this period 53% of patients who were working remained in employment. Of the patients who were not working at baseline, 9% had returned to work at follow-up. However, of those working at baseline, 6% were unable to continue to work at follow-up. Age, fatigue severity, functional impairment, cognitive and behavioural responses, and depressive symptoms impacted on a patients' work status at follow-up.

CONCLUSIONS

The findings indicated that it is possible for people with CFS to remain in work or return to work, despite having had a disabling illness. Work-related outcomes should be targeted in all people of working age.

Some of the workforce face post COVID after the acute phase of the illness: The employer’s supportive role

BACKGROUND: A considerable proportion of workers that recover from an acute phase of COVID-19 are confronted with post COVID-19 symptoms of varying severity and duration. Employers have an important role in addressing this new condition. OBJECTIVE: The aim of this study was to review organisational practises that could help employees suffering from long COVID-19 return to work and to link these suggestions to theoretical frameworks from the field of work and organisational psychology. METHODS: Since scientific publications on post COVID-19 are published daily, but sound empirical studies are still scarce, the synthesis of the scientific and professional literature was performed in the form of a narrative review. RESULTS: The results were organised according to the healthy workplace model and explained through the lens of the job demands-resources theory. The role of the employer has three aspects: collaboration, instructional pillars, and key actors. The main guidelines for implementation of the policies are an individualised approach, flexibility, and support. Supportive policies, practises, and relationships might have a direct impact on workers’ psychological resources. CONCLUSIONS: The model could help employers understand the conditions and necessary adaptations for workers with post COVID-19, as well as advance research in work and organisational psychology.

Patients' hopes for recovery from myalgic encephalomyelitis and chronic fatigue syndrome: Toward a "recovery in" framework

OBJECTIVE

There is no consensus on recovery from myalgic encephalomyelitis and chronic fatigue syndrome, which has spawned debates when interpreting outcome research. Within these debates, the patient voice is often neglected. This study aimed to understand how patients conceptualize recovery - regarding the definition and possibility of recovery.

METHOD

We conducted in-depth, semi-structured interviews with 10 older (above age 50) female patients with myalgic encephalomyelitis or chronic fatigue syndrome. Data were analyzed using a deductive thematic analysis.

RESULTS

Our sample viewed recovery as functioning without fear of relapse, returning to previous roles and identities, and achieving a sustained absence of symptoms. Participants expressed skepticism that reaching recovery from myalgic encephalomyelitis and chronic fatigue syndrome exists but working toward significant improvement through coping is a viable goal. Although many accepted they would never reclaim full functioning, participants continued to experience uncertainty about their future with unclear prognostic goals and limited treatment options.

DISCUSSION

Recovery is more than just symptom reduction. Outcome research should incorporate well-being measures like identity, meaning and quality of life, and personal empowerment to enhance recovery definitions. When communicating treatment goals, providers might convey cautious optimism for complete symptom remission, while emphasizing that living a fulfilling life through effective coping strategies is possible.

Factors associated with work status in chronic fatigue syndrome

BACKGROUND

Work status in people with chronic fatigue syndrome (CFS) has not been extensively researched.

AIMS

To explore occupational outcomes in patients with CFS by socio-demographic, well-being and disease characteristics.

METHODS

We assessed cross-sectional data from patients attending a UK specialist CFS treatment service between 1 January 2007 and 31 December 2014. The main outcome was self-reported current employment status: currently in employment, temporarily interrupted employment or permanently interrupted employment. Other variables included sex, age, ethnicity, education, marital status, CFS duration, fatigue severity, anxiety, depression, activity limitations and functional impairment. We used multinominal logistic regression models to identify factors associated with current work status.

RESULTS

Two hundred and seventy-nine (55%) patients were currently working, with 83 (16%) reporting temporarily interrupted employment and 146 (29%) stopping work altogether. Factors strongly associated with permanently interrupted employment were older age (adjusted odds ratio (AOR) 5.24; 95% CI 2.67-10.28), poorer functioning (AOR 6.41; 95% CI 3.65-11.24) and depressive symptoms (AOR 2.89; 95% CI 1.82-4.58) compared to patients currently working. Higher educated patients (AOR 0.60; 95% CI 0.37-0.97) and being in a relationship (AOR 0.34; 95% CI 0.21-0.54) were associated with being currently employed. Anxiety symptoms were common; 230 patients (45%) met caseness criteria.

CONCLUSIONS

Many patients with CFS were not working. This was exacerbated by high levels of depressive symptoms. Health professionals should assess co-morbid mental health conditions and consider treatment options when patients with CFS present themselves. The early involvement of occupational health practitioners is recommended to maximize the chances of maintaining employment.

Unemployment and work disability in individuals with chronic fatigue syndrome/myalgic encephalomyelitis: a community-based cross-sectional study from Spain

BACKGROUND

Few reports have examined the association between unemployment and work disability in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). This study explored the key determinants of work disability in a CFS/ME cohort.

METHODS

A community-based prospective study included 1086 CFS/ME patients aged 18-65 years. Demographic and clinical characteristics and outcome measures were recorded. Multiple linear regression analysis was performed to identify key risk indicators of work disability.

RESULTS

Four hundred and fifty patients with CFS/ME were employed (41.4%) and 636 were unemployed (58.6%). Older age at pain onset (OR: 1.44; 95% CI: 1. 12-1.84, autonomic dysfunction (OR: 2.21; 95% CI: 1.71-2.87), neurological symptom (OR: 1.66; 95% CI: 1. 30-2.13) and higher scores for fatigue (OR: 2.61; 95% CI: 2.01-3.39), pain (OR: 2.09; 95% CI: 1.47-2.97), depression (OR: 1.98; 95% CI: 1. 20-3.26), psychopathology (OR: 1.98; 95% CI: 1.51-2.61) and sleep dysfunction (OR: 1.47; 95% CI: 1. 14-1.90) were all associated with a higher risk of work disability due to illness.

CONCLUSIONS

Using an explanatory approach, our findings suggest that unemployment is consistently associated with an increased risk of work disability due to CFS/ME, although further more rigorous research is now needed to help in targeting interventions at the workplace.

Suicidal ideation in non-depressed individuals: The effects of a chronic, misunderstood illness

Chronic illness is a risk factor for suicide but is often explained with depression. Research has shown an increased suicide rate in patients with myalgic encephalomyelitis and chronic fatigue syndrome, but specific risk factors have been unexplored. We qualitatively analyzed responses from 29 patients who endorsed suicidal ideation but did not meet depression criteria. Two themes were developed: (1) feeling trapped and (2) loss of self, loss of others, stigma and conflict. Myalgic encephalomyelitis and chronic fatigue syndrome caused patients severe disability, restructured their lives, and inflicted serious pain. Participants emphasized that they were not depressed, but felt trapped by the lack of treatments available.

Effects of a short-term aquatic exercise intervention on symptoms and exercise capacity in individuals with chronic fatigue syndrome/myalgic encephalomyelitis: a pilot study

PURPOSE

This pilot pre-and post-intervention study investigated the effects of a short-term aquatic exercise programme on physiological outcomes, symptoms and exercise capacity in women with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME).

METHODS

Eleven women (54.8 ± 12.4 year) volunteered for the 5-week program; an initial 20-min aquatic exercise session then two self-paced 20-min sessions per week for 4 weeks. Pre- and post-intervention outcomes were physiological measures, 6 min Walk Test (6MWT), perceived exertion (RPE), hand grip strength, Sit-to-Stand, Sit-Reach test, Apley's shoulder test, FACIT questionnaire, and 24-h post-test tiredness and pain scores (0-10 visual analogue scale). Heart rates, RPE, 24- and 48-h post-session tiredness/pain scores were recorded each session.

RESULTS

6MWT distance increased by 60.8 m (p = 0.006), left hand grip strength by 6 kg (p = 0.038), Sit-Reach test by 4.0 cm (p = 0.017), right shoulder flexibility by 2.9 cm (p = 0.026), FACIT scores by 8.2 (p = 0.041); 24-h post-test tiredness and pain decreased by 1.5 and 1.6, respectively (p = 0.002). There were significant post-intervention increases in exercising heart rates (6MWT 4- and 6-min time points), oxygen saturation at 2-min, and reduced RPE at 4-min. Weekly resting and exercising heart rates increased significantly during the study but RPE decreased; immediately post- and 24-h post-session tiredness decreased significantly. There were no reports of symptom exacerbation.

CONCLUSIONS

Five weeks of low-moderate intensity aquatic exercise significantly improved exercise capacity, RPE and fatigue. This exercise mode exercise may potentially be a manageable and safe physical activity for CFS/ME patients.

Poor self-reported sleep quality and health-related quality of life in patients with chronic fatigue syndrome/myalgic encephalomyelitis

Non-restorative sleep is a hallmark symptom of chronic fatigue syndrome/myalgic encephalomyelitis. However, little is known about self-reported sleep disturbances in these subjects. This study aimed to assess the self-reported sleep quality and its impact on quality of life in a Spanish community-based chronic fatigue syndrome/myalgic encephalomyelitis cohort. A prospective cross-sectional cohort study was conducted in 1,455 Spanish chronic fatigue syndrome/myalgic encephalomyelitis patients. Sleep quality, fatigue, pain, functional capacity impairment, psychopathological status, anxiety/depression and health-related quality of life were assessed using validated subjective measures. The frequencies of muscular, cognitive, neurological, autonomic and immunological symptom clusters were above 80%. High scores were recorded for pain, fatigue, psychopathological status, anxiety/depression, and low scores for functional capacity and quality of life, all of which correlated significantly (all p < 0.01) with quality of sleep as measured by the Pittsburgh Sleep Quality Index. Multivariate regression analysis showed that after adjusting for age and gender, the pain intensity (odds ratio, 1.11; p <0.05), psychopathological status (odds ratio, 1.85; p < 0.001), fibromyalgia (odds ratio, 1.39; p < 0.05), severe autonomic dysfunction (odds ratio, 1.72; p < 0.05), poor functional capacity (odds ratio, 0.98; p < 0.05) and quality of life (odds ratio, 0.96; both p < 0.001) were significantly associated with poor sleep quality. These findings suggest that this large chronic fatigue syndrome/myalgic encephalomyelitis sample presents poor sleep quality, as assessed by the Pittsburgh Sleep Quality Index, and that this poor sleep quality is associated with many aspects of quality of life.

Mortality in Patients with Myalgic Encephalomyelitis and Chronic Fatigue Syndrome

BACKGROUND

There is a dearth of research examining mortality in individuals with myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS). Some studies suggest there is an elevated risk of suicide and earlier mortality compared to national norms. However, findings are inconsistent as other researchers have not found significant increases in all-cause mortality for patients.

OBJECTIVE

This study sought to determine if patients with ME or CFS are reportedly dying earlier than the overall population from the same cause.

METHODS

Family, friends, and caregivers of deceased individuals with ME or CFS were recruited through social media, patient newsletters, emails, and advocate websites. This study analyzed data including cause and age of death for 56 individuals identified as having ME or CFS.

RESULTS

The findings suggest patients in this sample are at a significantly increased risk of earlier all-cause (M = 55.9 years) and cardiovascular-related (M = 58.8 years) mortality, and they had a directionally lower mean age of death for suicide (M = 41.3 years) and cancer (M =66.3 years) compared to the overall U.S. population [M = 73.5 (all-cause), 77.7 (cardiovascular), 47.4 (suicide), and 71.1 (cancer) years of age].

CONCLUSIONS

The results suggest there is an increase in risk for earlier mortality in patients with ME and CFS. Due to the small sample size and over-representation of severely ill patients, the findings should be replicated to determine if the directional differences for suicide and cancer mortality are significantly different from the overall U.S. population.

'The letting go, the building up, [and] the gradual process of rebuilding': identity change and post-traumatic growth in myalgic encephalomyelitis/chronic fatigue syndrome

The aim of this study was to explore the phenomenon of identity change and subsequent post-traumatic growth (PTG) in individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Ten participants (average illness duration 7.4 years) were interviewed (average length, 79 minutes) via a semi-structured interview schedule and verbatim transcriptions were analysed with interpretative phenomenological analysis. The four superordinate themes revealed were 'comparisons of past to present self: "you have to be someone else, and you have to live with that''', 'the effect of social isolation on identity and subsequent insights into others' behaviours', 'contemplation of future and identity: ''where do I go from here?"', and 'PTG: "the letting go, the building up, [and] the gradual process of rebuilding"'. These themes outlined the experiences of those with ME/CFS as they underwent changes in identity due to the limitations the condition imposed on activities and roles, understanding others' behaviours after a period of isolation, the comparison of the past self with the present self and finally, the positive growth that was noted by two of the interviewees with regards to a new 'true' self. Despite the distressing and unpredictable nature of ME/CFS, it appears that individuals with this disorder can experience personal growth.

Chronic fatigue syndrome after Giardia enteritis: clinical characteristics, disability and long-term sickness absence

Background

A waterborne outbreak of Giardia lamblia gastroenteritis led to a high prevalance of long-lasting fatigue and abdominal symptoms. The aim was to describe the clinical characteristics, disability and employmentloss in a case series of patients with Chronic Fatigue Syndrome (CFS) after the infection.

Methods

Patients who reported persistent fatigue, lowered functional capacity and sickness leave or delayed education after a large community outbreak of giardiasis enteritis in the city of Bergen, Norway were evaluated with the established Centers for Disease Control and Prevention criteria for CFS. Fatigue was self-rated by the Fatigue Severity Scale (FSS). Physical and mental health status and functional impairment was measured by the Medical Outcome Severity Scale-short Form-36 (SF-36). The Hospital Anxiety and Depression Scale (HADS) was used to measure co-morbid anxiety and depression. Inability to work or study because of fatigue was determined by sickness absence certified by a doctor.

Results

A total of 58 (60%) out of 96 patients with long-lasting post-infectious fatigue after laboratory confirmed giardiasis were diagnosed with CFS. In all, 1262 patients had laboratory confirmed giardiasis. At the time of referral (mean illness duration 2.7 years) 16% reported improvement, 28% reported no change, and 57% reported progressive course with gradual worsening. Mean FSS score was 6.6. A distinctive pattern of impairment was documented with the SF-36. The physical functioning, vitality (energy/fatigue) and social functioning were especially reduced. Long-term sickness absence from studies and work was noted in all patients.

Conclusion

After giardiasis enteritis at least 5% developed clinical characteristics and functional impairment comparable to previously described post-infectious fatigue syndrome.

An assessment of prospective memory retrieval in women with chronic fatigue syndrome using a virtual-reality environment: an initial study

People with chronic fatigue syndrome (CFS) have increased rates of depression, anxiety, and illness intrusiveness; they may also suffer from cognitive problems such as retrospective memory (RM) deficits and concentration difficulties that can stem from diminished information-processing capability. We predicted that this diminished capacity may also lead to deficits in other cognitive functions, such as prospective memory (ProM). Event-, time-, and activity-based ProM was assessed in 11 women with CFS and 12 healthy women using a computer-generated virtual environment (VE). RM was assessed using a free-recall test, and subjective assessment of both ProM and RM was assessed by questionnaire. Groups were equivalent in age and measures of IQ. People with CFS performed slightly worse than healthy controls on both the event- and time-based ProM measures, although these were not statistically significant. However, the CFS group performed significantly worse than the healthy controls on both the free recall-task and on subjective assessment of both RM and ProM. Women with CFS do have some subtle decrements in memory, particularly RM. However, it is possible that the decrements found in the present sample would be greater in real life. Further studies utilizing both healthy controls and illness controls are now needed to ascertain how sensitive the VE measure is and to inform the development of tasks in the VE that place progressively increasing demands on working memory capacity.
