Work Ability in Fibromyalgia: An Update in the 21st Century

Social costs associated with fibromyalgia in Spain

BACKGROUND

Fibromyalgia is a chronic rheumatic disease of unknown aetiology, highly disabling and mainly affecting women. The aim of our work is to estimate, on a national scale, the economic impact of this disease on the employment of patients and non-professional (informal) care dimension.

METHODS

Survey on Disabilities, Autonomy and Dependency carried out in Spain in 2020/21 was used to obtain information on disabled individuals with AD and their informal caregivers. Six estimation scenarios were defined as base case, depending on whether the maximum daily informal caregiving time was censored or not, and on the approach chosen for the valuation of informal caregiving time (contingent valuation and replacement time). Another six conservative scenarios were developed using the minimum wage for the estimation of labour losses.

RESULTS

Our estimates range from 2,443.6 (willingness to pay, censored informal care time) to 7,164.8 million euros (replacement cost, uncensored informal care time) (base year 2021). Multivariate analyses identified that the degree of dependency of the person suffering from fibromyalgia is the main explanatory variable for both the probability of being employed and the time spent in informal care. Conservative scenarios estimates range from 1,807 to 6,528 million euros.

CONCLUSIONS

The high economic impact revealed should help to position a health problem that is relatively unknown in society and for which there are significant research and care gaps to be filled.

Perceived Stress and Life Stressors in Adults with and without Fibromyalgia

Chronic medical conditions (i.e., chronic widespread pain) may contribute to accelerated/accentuated aging, such that middle-aged individuals with comorbidities may actually show increased declines in physical, cognitive, and mental health compared to normal aging adults. We examined perceived stress, life stressors, and depression in adults with and without fibromyalgia, a chronic pain condition. Ninety-four participants (52% with fibromyalgia, 78% female) aged 50 to 93 were administered the Perceived Stress Scale, Social Readjustment Rating Scale, and Beck Depression Inventory. Hierarchical regression analyses were conducted: the predictor variables were age, gender, fibromyalgia status, depression, and fibromyalgia-depression interaction. The interaction term significantly predicted perceived stress, but not life stressors. Depression significantly predicted stress for Social Readjustment Rating Scale measures after controlling for covariates. Significant associations were found between perceived stress and life stressors in all participants. In addition, those with fibromyalgia were significantly more likely to report higher levels of stress above standardized scores on both the Perceived Stress Scale and the Social Readjustment Rating Scale. Finally, depressive symptoms played a more significant role than fibromyalgia status in predicting life stressors. Conclusions: These findings emphasize the importance of assessing different types of stress and stressors in individuals with chronic widespread pain and/or depression in mid-life and beyond to better treat individuals with these conditions.

Suicidal ideation in female individuals with fibromyalgia and comorbid obesity: prevalence and association with clinical, pain-related, and psychological factors

OBJECTIVE

Individuals with fibromyalgia report alarming levels of suicidal ideation, and comorbidity with other chronic health conditions such as obesity-a risk factor for suicidal ideation per se-could further complicate the clinical picture. The aim of this study is to determine, in a sample of women with fibromyalgia and comorbid obesity, the prevalence of suicidal ideation and to evaluate clinical, pain-related and psychological factors associated with suicidal ideation.

METHODS

In total, 156 female individuals with fibromyalgia and obesity were recruited and completed a series of self-report measures that assessed (i) the level of pain intensity, (ii) depressive symptomatology, (iii) sleep quality, and (iv) pain catastrophizing. Suicidal ideation was evaluated by item #9 of the Beck Depression Inventory. In addition, information regarding previous suicide attempts and current opioid use was collected.

RESULTS

3n sum, 7.8% of participants reported presence of suicidal ideation. According to the results of the multiple logistic regression, depressive symptomatology, sleep quality, and pain catastrophizing were associated with the presence of suicidal ideation.

DISCUSSION

The presence of suicidal ideation in our sample was significantly associated with depressive symptomatology, sleep quality, and pain catastrophizing. Our findings are the first to suggest a unique (ie, independent of depressive symptomatology, and sleep quality) association between pain catastrophizing and suicidal ideation in the context of fibromyalgia and comorbid obesity. In order to prevent and reduce suicidal ideation, these factors should be assessed and targeted in interventions for pain management. Future research should investigate the extent to which addressing depressive symptoms, sleep quality, and pain catastrophizing reduces suicidal ideation.

Health inequities and societal costs for patients with fibromyalgia and their spouses: a Danish cohort study

OBJECTIVE

To assess the burden of illness of people with fibromyalgia (FM) and their spouses compared with selected match populations in Denmark.

METHODS

Population-based, cohort case-control study using data from Danish registries from 1994 to 2021. Individuals with an FM diagnosis were identified from the National Patient Register (2008-2019) and randomly matched to a 1:4 general population comparator. Spouses or persons co-living with subjects with FM at the time of diagnosis were compared with matched comparator spouses. Healthcare and societal costs, socioeconomic status and occurrence of comorbidities were evaluated for subjects with FM, spouses and controls.

RESULTS

9712 subjects with FM (94.9% females, mean age 50 years) and 5946 spouses were included. At year of diagnosis, subjects with FM had significantly more comorbidities compared with controls, including significantly more comorbid rheumatic disorders. The highest risk at the time of FM diagnosis was a comorbid diagnosis of ankylosing spondylitis (OR 7.0, 95% CI 4.9 to 10.0). Significantly more comorbidities were also observed in spouses. Subjects with FM and spouses had higher healthcare and public transfer costs and lower income from employment at all timepoints. Loss of income from employment in subjects with FM occurred years before establishment of the FM diagnosis. The employment rate after diagnosis was 22%. 10 years after the FM diagnosis, 50% received disability pension as compared with 11% of matched controls. The observed net average increased societal cost for subjects with FM amounted to €27 193 per patient-year after diagnosis.

CONCLUSION

FM has major health and socioeconomic consequences for patients, their partners and society and call for improved healthcare strategies matching patients' needs.

Psychometric testing of the Rheumatoid Arthritis Work Instability Scale in employed people with fibromyalgia

OBJECTIVE

The aim of the study was to establish whether the Rheumatoid Arthritis Work Instability Scale (RA-WIS), in its current form, is applicable for use with employed people with fibromyalgia (FM) to identify the risk of work disability and need for work rehabilitation.

METHODS

Content validity was first investigated using cognitive debriefing interviews. Participants completed a postal questionnaire. Construct validity was assessed using Rasch analysis. Concurrent validity included testing between the RA-WIS and work (e.g., Workplace Activity Limitations Scale) and health (FM Impact Questionnaire-Revised (FIQ-R) scales. Two weeks later, participants were mailed a second questionnaire to measure test-retest reliability.

RESULTS

Interviews were conducted with 13 participants with FM. All RA-WIS items were considered very or extremely relevant by almost all participants, with only one suggesting other items (anxiety and brain fog). Questionnaire responses were analysed from 156 employed participants: 94% women; 45.71 (SD 10.05) years of age; with time since FM diagnosis 2.99 (4.17) years (symptom duration 8.36 (SD 7.16) years). The RA-WIS mostly satisfied Rasch model requirements and a Rasch transformation scale was created. Concurrent validity was generally good (rs = 0.55-0.66) with work scales and the FIQ-R. Internal consistency (Person Separation Index values) was consistent with group use in FM, not individual level use. Test-retest reliability was excellent, with intraclass coefficient (2, 1) = 0.90.

DISCUSSION

The RA-WIS is valid and reliable for group use in employed people with FM. However, further work is needed to develop a WIS for individual use in FM.

The correlation between occupation type and fibromyalgia severity

BACKGROUND

Fibromyalgia (FM) is a chronic pain disorder associated with financial burden, decreased work productivity and absenteeism. Occupational stressors and specific employment factors may contribute to the severity of FM.

AIMS

To determine if occupation type or employment status correlates with FM diagnostic and severity parameters, as assessed via validated instruments including tender points (TP), Widespread Pain Index (WPI), Symptom Severity (SS) and pain regions.

METHODS

We performed a cross-sectional study of 200 adult patients diagnosed with FM at a single-centre FM clinic. Demographic and clinical data were extracted from the electronic medical records. Occupations were manually grouped in an iterative modified-Delphi approach and participants were grouped by employment status (Working, Not Working/Disabled or Retired) for analysis.

RESULTS

In our cohort, 61% were employed and 24% were not working/disabled, while the remainder were students, homemakers or retired. SS score was significantly higher (P < 0.001) in not working/disabled patients compared to those employed. Business owners had the lowest TP count (median = 14) and the lowest median SS score (median = 7). WPI was highest for Others (Arts/Entertainment, Driver/Delivery and Housekeeper/Custodian workers; median=16) and the lowest for Retail/Sales/Wait Staff (median = 11).

CONCLUSIONS

Work-related factors, occupation type and employment status correlate with diagnostic and severity parameters of FM. Employed participants had significantly lower SS scores suggesting that work loss correlates with SS. Participants employed in entry-level jobs or jobs with higher physical or financial stressors may experience greater FM symptoms. Further studies are required to explore work-related factors and their impact on the diagnostic and severity parameters of FM.

Assessing workers with fibromyalgia: what should occupational physicians know?

Fibromyalgia is a chronic pain syndrome with a complex multifactorial etiopathogenesis that more frequently affects women. Although widespread pain is the dominant feature, fibromyalgia incorporates a wide variety of symptoms, such as fatigue, unrefreshed sleep, and cognitive and mood disorders. Central sensitization to pain is a key element in the pathophysiology of this syndrome. Due to its prevalence and repercussions on quality of life and work productivity, fibromyalgia is a common condition in occupational medicine outpatient clinics. Thus, physicians must be attentive to its symptoms to facilitate diagnosis and management. This article will address basic topics about fibromyalgia, including: epidemiology, predisposing factors, pathophysiological considerations, clinical manifestations, classification criteria, differential diagnosis, basic principles of treatment, and the contribution of occupational physicians.

Work situation, work ability and expectation of returning to work in patients with systemic autoimmune myopathies

OBJECTIVES

To document the work situation, the work ability and the expectation of returning to work among adult patients with systemic autoimmune myopathies (SAMs), and to identify the factors associated with each of these outcomes.

METHODS

Cross-sectional study. The work situation (performing paid work vs out of work) was ascertained via a structured questionnaire. For those who were working, we applied the Work Ability Index (WAI; scale 7-49); and for those who were out of work, we applied the Return-to-Work Self-Efficacy questionnaire (RTW-SE; scale 11-66).

RESULTS

Of the 75 patients with SAMs included, 33 (44%) were doing paid work and 42 (56%) were out of work. The work situation was independently associated with physical function, assessed by the Health Assessment Questionnaire-Disability Index (HAQ-DI). A 1-point increase in the HAQ-DI (scale 0-3) decreased the chance of doing paid work by 66% (95% CI: 0.16, 0.74; P = 0.007). Patients performing paid work had a mean WAI of 33.5 (6.9). The following variables were associated with a decrease in the WAI score in the regression model: female sex (-5.04), diabetes (-5.94), fibromyalgia (-6.40), fatigue (-4.51) and severe anxiety (-4.59). Among those out of work, the mean RTW-SE was 42.8 (12.4). Cutaneous manifestations and >12 years of education were associated with an average increase of 10.57 and 10.9 points, respectively, in the RTW-SE. A 1-point increase in the HAQ-DI decreased the RTW-SE by 4.69 points.

CONCLUSION

Our findings highlight the poor work participation in a well-characterized sample of working-age patients with SAMs. Strategies to improve work-related outcomes in these patients are urgently needed.

The cumulative effect of fibromyalgia symptoms on cognitive performance: The mediating role of pain

Fibromyalgia (FMS) is a chronic condition that encompasses widespread pain associated with cognitive impairment and significant emotional distress related to functional disability. This study aimed to obtain evidence of the role of pain in the effect of time since FMS diagnosis and cognitive performance using a novel online protocol of neuropsychological evaluation since the COVID-19 pandemic has challenged traditional neuropsychology testing leading to the need for novel procedures transitioning to tele-neuropsychology. A sample of 70 adult women was evaluated (50 with FMS and 19 controls) using online questionnaires that evaluated pain and executive functioning (impulsivity, inhibition control, monitoring, and planning). Afterward, participants were evaluated by trained neuropsychologists in a 30 min online session using virtually adapted cognitive tests: the Hopkins Verbal Learning Test (memory), the Symbol-Digit Modalities Test (attention and speed processing), the F-A-S test (verbal fluency), and Digit Span tests (working memory). We found that the time of FMS diagnosis has an effect on cognitive functioning predominantly mediated by pain. Our results point out the role of pain as a mediator on cognitive performance, specifically in executive functions which are directly affected by the cumulative effect of the time of diagnosis. Furthermore, the importance of considering a broader perspective for assessment and treatment including novel procedures via tele-neuropsychology.

Prognostic factors for work disability in patients with chronic widespread pain and fibromyalgia: protocol for a cohort study

INTRODUCTION

The association between chronic widespread pain (CWP) and disability is well established. Although research support large interindividual differences in functional outcomes, limited studies are available on the socio-economic consequences of offering stratified treatment based on prognostic factors. Identification of predictors of long-term functional outcomes such as work disability as a critical consequence, could assist early and targeted personalised interventions. The primary objective of this cohort study is to identify prognostic factors for the primary endpoint work status (employed and working vs not working) in patients with CWP assessed 3 years from baseline, that is, at referral for specialist care.

METHODS AND ANALYSES

Data are collected at the diagnostic unit at Department of Rheumatology, Frederiksberg Hospital. The first 1000 patients ≥18 years of age registered in a clinical research database (DANFIB registry) with CWP either 'employed and working' or 'not working' will be enrolled. Participants must meet the American College of Rheumatology 1990 definition of CWP, that is, pain in all four body quadrants and axially for more than 3 months and are additionally screened for fulfilment of criteria for fibromyalgia. Clinical data and patient-reported outcomes are collected at referral (baseline) through clinical assessment and electronic questionnaires. Data on the primary endpoint work status at baseline and 3 years from baseline will be extracted from the Integrated Labour Market Database, Statistics Denmark and the nationwide Danish DREAM database. Prognostic factor analysis will be based on multivariable logistic regression modelling with the dichotomous work status as dependent variable.

ETHICS AND DISSEMINATION

Sensitive personal data will be anonymised according to regulations by the Danish Data Protection Agency, and informed consent are obtained from all participants. Understanding and improving the prognosis of a health condition like CWP should be a priority in clinical research and practice. Results will be published in international peer-reviewed journals.

Placebo Responses and Their Clinical Implications in Fibromyalgia: A Meta-Analysis Using SSRI and SNRI Trials

Background: Fibromyalgia (FM) is a chronic primary pain condition, associated with widespread musculoskeletal pain, disturbed sleep, fatigue, cognitive dysfunction, and a range of comorbid conditions such as irritable bowel syndrome, and depression. Despite its high prevalence of 2% in the general population, FM continues to pose scientific and clinical challenges in definition, etiology, and day-to-day management. In terms of treatment, FM can be treated with selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs). Objective: Patients with FM and other chronic primary pain syndromes are known to experience substantial and clinically relevant placebo effects. An update of the placebo responses for various outcomes in the FM population and especially a discussion about clinical implications is therefore needed. Methods: We used data from a large data pool that includes randomized controlled trials (RCTs) examining within-placebo mean change scores of baseline vs. follow-up assessments in FM trials of SSRIs and SNRIs. The primary outcomes were pain, functional disability, and depression and using different scales. We assessed heterogeneity of included trials. Results: A total of 29 RCTs with N = 8,453 patients suffering from FM were included in our analysis. Within-placebo mean change scores of baseline vs. follow-up assessments were large for pain (mean change = 2.31, 95% CI: 0.42-4.21, p = 0.017), functional disability (mean change = 3.31, 95% CI: 2.37-4.26, p < 0.000), and depression (mean change = 1.55, 95% CI: 0.92-2.18, p < 0.000). Heterogeneity was found to be large for all outcomes. Impact: Our results provide preliminary evidence that placebo responses, which also consist of non-specific effects, might play a role in the treatment of FM. Furthermore, we highlight limitations of our analyses and make suggestions for future studies.

Effects of a mindfulness-based and acceptance-based group programme followed by physical activity for patients with fibromyalgia: a randomised controlled trial

INTRODUCTION

Non-pharmacological approaches are recommended as first-line treatment for patients with fibromyalgia. This randomised controlled trial investigated the effects of a multicomponent rehabilitation programme for patients with recently diagnosed fibromyalgia in primary and secondary healthcare.

METHODS

Patients with widespread pain ≥3 months were referred to rheumatologists for diagnostic clarification and assessment of study eligibility. Inclusion criteria were age 20-50 years, engaged in work or studies at present or during the past 2 years, and fibromyalgia diagnosed according to the American College of Rheumatology 2010 criteria. All eligible patients participated in a short patient education programme before inclusion and randomisation. The multicomponent programme, a 10-session mindfulness-based and acceptance-based group programme followed by 12 weeks of physical activity counselling was evaluated in comparison with treatment as usual, that is, no treatment or any other treatment of their choice. The primary outcome was the Patient Global Impression of Change (PGIC). Secondary outcomes were self-reported pain, fatigue, sleep quality, psychological distress, physical activity, health-related quality of life and work ability at 12-month follow-up.

RESULTS

In total, 170 patients were randomised, 1:1, intervention:control. Overall, the multicomponent rehabilitation programme was not more effective than treatment as usual; 13% in the intervention group and 8% in the control group reported clinically relevant improvement in PGIC (p=0.28). No statistically significant between-group differences were found in any disease-related secondary outcomes. There were significant between-group differences in patient's tendency to be mindful (p=0.016) and perceived benefits of exercise (p=0.033) in favour of the intervention group.

CONCLUSIONS

A multicomponent rehabilitation programme combining patient education with a mindfulness-based and acceptance-based group programme followed by physical activity counselling was not more effective than patient education and treatment as usual for patients with recently diagnosed fibromyalgia at 12-month follow-up.

Serial whole-body cryotherapy in fibromyalgia is effective and alters cytokine profiles

Introduction

Whole-body cryotherapy (WBC) has shown to be beneficial in the treatment of fibromyalgia (FM). There is cumulative evidence that cytokines play a crucial role in FM. It’s unknown whether clinical effects of WBC can be demonstrated at the molecular level and how long the effects last.

Methods

We compared effects of serial WBC (6 sessions (− 130 °C in 6 weeks) in FM patients and healthy controls (HC). Primary outcome was the change in pain level (visual analogue scale 0–100 mm) after 6 sessions. Secondary outcomes were a change in disease activity (revised Fibromyalgia Impact Questionnaire) and pain after 3 sessions and 3 months after discontinued therapy and in cytokine levels (interleukin (IL-)1, IL-6, tumor necrosis factor α (TNF-α) and IL-10). The patients’ opinions on the satisfaction, effectiveness and significance of WBC were evaluated.

Results

Twenty-three FM patients and 30 HC were enrolled. WBC resulted in a significant reduction in pain and disease activity after 3 and 6 sessions. No clinical benefit could be measured 3 months after discontinued treatment. Overall, probands were satisfied with WBC and considered WBC to be important and effective. FM patients had significantly different levels of IL-1, IL-6, TNF-α and IL-10 at each reading point compared to HC. Levels of IL-1, IL-6 and IL-10 were significantly altered over time in FM patients. Compared to HC FM patients showed a significantly different response of IL1, − 6 and − 10 to WBC.

Conclusion

Serial WBC is a fast acting and effective treatment for FM. Proven effects of WBC may be explained by changes in cytokines.

A comparison of visual analog scale and shear-wave ultrasound elastography data in fibromyalgia patients and the normal population

[Purpose] The aim of this study was to compare Visual Analog Scale (VAS) values with the Shear Wave Elastography (SWE) values of rhomboid major muscles in fibromyalgia (FM) patients with those of a normal healthy population. [Participants and Methods] Evaluation was made of 53 female patients diagnosed with FM according to the American Collage of Rheumatology criteria, and a control group of 47 healthy volunteers with a VAS score of 0. All the patients were applied with ultrasonography. The severity of pain was measured using a VAS. [Results] Mean age was calculated as 39 years (range, 23–60 years) in the patient group and 37 years (range, 21–58 years) in the control group. The mean SWE value of the rhomboid major muscle of the patients was 4.74 m/sn and 70.21 kPa on the right side and 4.46 m/sn and 58.78 kPa on the left side. In the control group, these values were 4.18m/sn and 55.03 kPa on the right side and 3.78 m/sn and 44.21 kPa on the left side. The mean VAS score of the patients was 7.3. [Conclusion] The use of SWE values could be more objective than the subjective parameter of the VAS score in the evaluation of the severity of pain in fibromyalgia.

Does work have to be so painful? A review of the literature examining the effects of fibromyalgia on the working experience from the patient perspective

Background

Chronic pain conditions, such as fibromyalgia, adversely affect individuals’ abilities to work.

Aim

The aim of this study was to examine, from the perspective of patients, the effects that fibromyalgia symptoms had on their ability to work, the challenges that they encountered in the workplace that did not foster their continued employment, and the types of modifications to their work or workplace that they thought would facilitate their productivity and ability to work.

Methods

A scoping review method, applying techniques of systematic review, was used to conduct a research synthesis of the literature regarding fibromyalgia and work that looked at this issue from the patient perspective.

Results

A variety of themes emerged from the analysis and could be broadly categorized into (1) the work experience was a challenging one with which to cope; (2) relationships were strained at work; (3) clinical symptoms had repercussions on subjects’ attitudes toward work and the relation to life outside of work; and (4) a variety of possible solutions were considered to help subjects better cope with fibromyalgia and work.

Conclusions

Strategies that potentially could foster continued employment of patients with fibromyalgia include those at the micro, meso, and macro levels. Health care providers can support patients’ employment goals by collaborating with patients and their employers, dispelling stigma regarding the illness, and providing practical and specific advice regarding workplace accommodations.

Burden of Illness Due to Fibromyalgia in a Neurology Clinic

Background  Fibromyalgia (FM) is a common disorder in general population and it causes an increased patient load in hospitals and specialty clinics. FM attendance will be high in clinics dealing with neuropathic pain and other pain syndromes. Though prevalence of FM has been studied in community and pain clinics in other countries, it has not so far been studied in India. So, a study is relevant and hence it was planned in neurology clinic of a teaching government hospital. At present, they are treated mainly by nonsteroidal anti-inflammatory drugs (NSAIDs) which are public health hazard. Methods  Using 2016 revision of 2010/2011 American College of Rheumatology criteria of FM, patients were screened in neurology OPD. Proportion and clinical profile were noted. Study was continued for 6 months till the sample size was met. Results  A total of 2,300 patients were screened. Two hundred and ninety-eight FM patients were identified among them. Proportion was 12.96%. Delayed diagnosis of more than a year occurred in 55%. Only 29.2% were treated, but none was offered cognitive behavioral therapy (CBT) before. NSAIDs for pain were given for 51.01%. Conclusion  Proportion of FM detected is considerable. Affection of homemakers and manual laborers, delayed diagnosis, coexisting comorbid illness, and treatment of pain with NSAIDs are causes of concern. Clinicians should be sensitized to clinical profile and criteria of FM. Patients should be diagnosed and treated by CBT at the earliest and NSAIDs should be avoided as far as possible.

Effectiveness of Exercise on Fatigue and Sleep Quality in Fibromyalgia: A Systematic Review and Meta-analysis of Randomized Trials

OBJECTIVES

To determine the effects of exercise on fatigue and sleep quality in fibromyalgia (primary aim) and to identify which type of exercise is the most effective in achieving these outcomes (secondary aim).

DATA SOURCES

PubMed and Web of Science were searched from inception until October 18, 2018.

STUDY SELECTION

Eligible studies contained information on population (fibromyalgia), intervention (exercise), and outcomes (fatigue or sleep). Randomized controlled trials (RCT) testing the effectiveness of exercise compared with usual care and randomized trials (RT) comparing the effectiveness of 2 different exercise interventions were included for the primary and secondary aims of the present review, respectively. Two independent researchers performed the search, screening, and final eligibility of the articles. Of 696 studies identified, 17 RCTs (n=1003) were included for fatigue and 12 RCTs (n=731) for sleep. Furthermore, 21 RTs compared the effectiveness of different exercise interventions (n=1254).

DATA EXTRACTION

Two independent researchers extracted the key information from each eligible study.

DATA SYNTHESIS

Separate random-effect meta-analyses were performed to examine the effects from RCTs and from RTs (primary and secondary aims). Standardized mean differences (SMD) effect sizes were calculated using Hedges' adjusted g. Effect sizes of 0.2, 0.4, and 0.8 were considered small, moderate, and large. Compared with usual care, exercise had moderate effects on fatigue and a small effect on sleep quality (SMD, -0.47; 95% confidence interval [CI], -0.67 to -0.27; P<.001 and SMD, -0.17; 95% CI, -0.32 to -0.01; P=.04). RTs in which fatigue was the primary outcome were the most beneficial for lowering fatigue. Additionally, meditative exercise programs were the most effective for improving sleep quality.

CONCLUSIONS

Exercise is moderately effective for lowering fatigue and has small effects on enhancing sleep quality in fibromyalgia. Meditative exercise programs may be considered for improving sleep quality in fibromyalgia.

Prevalence of obstructive sleep apnea in female patients with fibromyalgia

Objectives:

To determine the prevalence of obstructive sleep apnea in female patients with fibromyalgia (FM) presenting to physical therapy outpatient clinics.

Methods:

The 36-item short form health survey (SF-36) questionnaire, Berlin test, and epworth sleepiness scale were administered, along with a polysomnography to 38 female patients. This cross-sectional study comprised diagnosed with FM according to the diagnostic criteria of the American College of Rheumatology, between March 2017 and August 2019, at the Faculty of Medicine Hospital, Çanakkale Onsekiz Mart University, Çanakkale, Turkey.

Results:

Of the participants, 65.9% were found to have obstructive sleep apnea (OSA). Patients with OSA were older and had a higher disease activity score for FM. A strong positive correlation was identified between the apnea-hypopnea index (AHI) and the FA disease activity score. A negative correlation was found between AHI and the subscales of SF-36.

Conclusion:

A clinical assessment of female patients with FM requires a multidisciplinary approach, and patients with excessive daytime sleepiness in particular are recommended to undergo polysomnography. The authors believe that the early detection and treatment of accompanying OSA will contribute not only to the quality of life, but also to the survival of patients with FM.

Decreased Chronic Widespread Pain on Nonworking Days Might Help Differentiate Work-Related Musculoskeletal Disorders From Fibromyalgia: A Cross-Sectional Study of Working Females

Objectives

This study aims to investigate whether fibromyalgia (FM) and work-related musculoskeletal disorders can be differentiated in working females by comparing their pain on nonworking and working days.

Patients and methods

The study included 142 female workers (mean age 30.0±6.5 years; range, 18 to 50 years) from five different work areas: 27 factory workers, 27 janitors, 25 data automation employees, 31 nurses, and 32 physiotherapists. Demographic characteristics were recorded. FM was diagnosed according to 2016 criteria of the American College of Rheumatology. The extended version of the Nordic Musculoskeletal Questionnaire was used to evaluate the participants’ musculoskeletal complaints and the severity of their pain. Pain was assessed with visual analog scale (VAS) scores on working and nonworking days. Differences in the participants’ VAS-Pain on working and nonworking days were compared. Sensitivity, specificity, receiver operating characteristic (ROC) curve and area under the curve (AUC) were used.

Results

Of the 142 working females, 32 (22.5%) were diagnosed with FM. There was a significant difference in nonworking day VAS-Pain scores between the FM patients and the work-related musculoskeletal disorder patients (p<0.001). Analysis of ROC curve for VAS-Pain difference scores yielded AUC of 0.860 (95% confidence interval=0.774–0.945) (p<0.001). ROC analysis identified 1.5 centimeters of VAS-Pain difference score as the cut-point for differentiating work-related musculoskeletal disorders and FM resulting in sensitivity of 97% and specificity of 96%. FM patients had significantly higher rates of positive answers to “visit health professionals,” “take medication,” and “sick leave” questions compared to patients with work-related musculoskeletal disorders (p<0.001).

Conclusion

The amount of the decrease in pain on nonworking days may help differentiate work-related musculoskeletal disorders from FM in working females. Therefore, evaluating pain on nonworking days may help clinicians diagnose and treat FM correctly.

Prediction of 2-year work participation in sickness absentees with neck or shoulder pain: the contribution of demographic, patient-reported, clinical and imaging information

Background

In cases of neck and shoulder pain, the responsibility for assessing work prognosis is held by clinicians with access to different domains of information. One of these domains is magnetic resonance imaging (MRI), and although MRI is increasingly used, it is unknown which domains of information contribute the most to the prediction of work prognosis. This retrospective cohort study explored the contribution of demographic, patient-reported, clinical, and MRI information to the prediction of work participation in sickness absentees with neck or shoulder pain.

Methods

From a secondary care setting, 168 sickness absentees with neck or shoulder pain were included. Based on registry data, a successful work outcome was defined as ≥50% work participation score (WPS) from Weeks 1 to 104 after enrolment. Prognostic variables were categorized into four domains (demographic, patient-reported, clinical, and MRI) resembling the order of information obtained in a clinical setting. Crude logistic regression analyses were used to identify prognostic variables for each domain (p < 0.2). This was followed by multivariable analyses including the identified variables in a domain-wise order. For each added domain, the probability of successful WPS was dichotomized leaving two possible classifications: ≥ 50% chance of successful WPS or not. In cross-tabulations of chance and the actual WPS outcome, positive and negative predictive values (PPV and NPV), sensitivity, specificity and area under the curve (AUC) were calculated.

Results

The combination of demographic and patient-reported variables yielded an NPV of 0.72 and a PPV of 0.67, while specificity was 0.82, sensitivity 0.54 and AUC 0.77. None of these values improved notably by adding clinical and MRI variables as predictors of successful WPS.

Conclusions

These results suggest that - among sickness absentees with neck or shoulder pain – clinical and MRI variables provide no additional information for the prediction of work participation compared with only demographic and patient-reported information.

Self-reported disability in women with fibromyalgia from a tertiary care center

Background

The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 is a generic instrument to assess disability. Pain and psychological factors seem to play a pronounced disabling role in fibromyalgia (FM). There are few studies that investigate the factors associated with disability in patients with fibromyalgia from the patient’s perspective. Information about FM disability using self-reported questionnaires is limited. This study aimed to assess the relationship between the ordinal response variable (degree of disability), and four explanatory variables: pain intensity, depression, anxiety, and alexithymia.

Methods

One hundred fifteen women with FM were enrolled in the cross-sectional study. For the assessment of disability the WHODAS 2.0 (36-item version) was used. Univariate and multivariate (ordinal logistic regression) analyses were performed to assess the relationship between pain (Visual Analogue Scale), depression and anxiety (Hospital Anxiety and Depression Scale), alexithymia (Modified Toronto Alexithymia Scale) and disability.

Results

Disability was detected by global WHODAS score in 114 patients (99%), with the corresponding percentages for mild, moderate and severe disability being 11.3, 46.96 and 40.87%, respectively. Global WHODAS score was more severe among subjects with depression (50 vs 36.4, p < 0.001, effect size = 0.33) and alexithymia (50 vs 33.6, p < 0.001, effect size = 0.38). Pain intensity mean scores for mild, moderate and severe disability were 5.0, 6.1 and 7.3, respectively (p < 0.001, omega-squared = 0.12). Pain intensity explained the global disability degree and its domains except for the cognitive one. Whereas, depression explained cognitive and personal relation domains. On the other hand, alexithymia explained global disability degree and all domains of WHODAS 2.0 questionnaire.

Conclusions

Most of the patients with fibromyalgia perceived themselves with moderate to severe disability. The main explanatory variables of the perceived disability were the pain intensity and psychological factors (alexithymia and depression).

Physical activity, sedentary behaviour, physical fitness, and cognitive performance in women with fibromyalgia who engage in reproductive and productive work: the al-Ándalus project

INTRODUCTION/OBJECTIVES

Reproductive labour refers to activities and tasks directed at caregiving and domestic roles, such as cleaning, cooking, and childcare. Productive labour refers to activities that involve economic remuneration. The aim of the present study was to analyse physical activity, sedentary behaviour, physical fitness, and cognitive performance in women with fibromyalgia who engaged, or did not engage, in productive work.

METHOD

This cross-sectional study comprised 276 women with fibromyalgia from Andalusia (southern of Spain). Levels of physical activity (light, moderate, and vigorous) and sedentary behaviour were measured by an accelerometer. Physical fitness and cognitive performance were measured with a battery of performance-based tests.

RESULTS

More hours/week of homemaker-related tasks were associated with higher time spend in light physical activity and lower sedentary behaviour (P < 0.001 and P < 0.05, respectively). Furthermore, in comparison with those who only engaged in reproductive labour, women with fibromyalgia who engaged in productive work showed lower levels of sedentary behaviour and higher levels of light and moderate physical activity, physical fitness (except muscular strength), and cognitive performance (all, P < 0.05).

CONCLUSIONS

Altogether, our findings suggest that productive work is consistently related to better physical and cognitive functioning in women with fibromyalgia. If future research corroborates causality of our findings, then, to maintain women with fibromyalgia engaging in productive work may be strived for not only because of societal or economic reasons but also for better health. However, we should keep in mind that people with fibromyalgia have a chronic condition, and therefore, adaptations at the workplace are imperative.Key Points• Women with fibromyalgia, who spend more time in reproductive labour, have higher levels of light physical activity and lower sedentary behaviour; however, it is associated with poorer general health (as lower physical fitness or cognitive performance).• Household tasks are often seen as a responsibility associated with the gender roles that women with fibromyalgia perform, despite the feelings of incapacity they cause. Policies focused on reducing reproductive labour demands for fibromyalgia patients (i.e. social help on housework or childcare) might facilitate the inclusion of daily active behaviours.• People with fibromyalgia who engage in productive work seem to have better health outcomes than those who have not; however, we cannot forget that adaptations and flexibility at the workplace are imperative.

Illuminating an Invisible Epidemic: A Systemic Review of the Clinical and Economic Benefits of Early Diagnosis and Treatment in Inflammatory Disease and Related Syndromes

Healthcare expenditures in the United States are growing at an alarming level with the Centers for Medicare and Medicaid Services (CMS) projecting that they will reach $5.7 trillion per year by 2026. Inflammatory diseases and related syndromes are growing in prevalence among Western societies. This growing population that affects close to 60 million people in the U.S. places a significant burden on the healthcare system. Characterized by relatively slow development, these diseases and syndromes prove challenging to diagnose, leading to delayed treatment against the backdrop of inevitable disability progression. Patients require healthcare attention but are initially hidden from clinician's view by the seemingly generalized, non-specific symptoms. It is imperative to identify and manage these underlying conditions to slow disease progression and reduce the likelihood that costly comorbidities will develop. Enhanced diagnostic criteria coupled with additional technological innovation to identify inflammatory conditions earlier is necessary and in the best interest of all healthcare stakeholders. The current total cost to the U.S. healthcare system is at least $90B dollars annually. Through unique analysis of financial cost drivers, this review identifies opportunities to improve clinical outcomes and help control these disease-related costs by 20% or more.
