Employment status of patients with neuromuscular diseases in relation to personal factors, fatigue and health status: A secondary analysis

The lived experience of facioscapulohumeral muscular dystrophy: A systematic review and synthesis of the qualitative literature

INTRODUCTION

In this review we sought to characterize the lived experience of people living with FSHD (pwFSHD) to help clinicians to orient their services to the needs of these individuals.

METHODS

Five electronic databases were systematically searched for qualitative research studies containing quotations from pwFSHD. ENhancing Transparency in REporting the Synthesis of Qualitative research and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines informed the methodology. Study quality was assessed using the Critical Appraisal Skills Programme Checklist tool, which measures the methodological quality of qualitative research. Data extracted from included studies were analyzed using thematic synthesis.

RESULTS

Ninety-nine pwFSHD took part in the six studies included in this review - from research teams based in two countries. Five descriptive themes emerged: "Engaging with life as symptoms progress"; "The emotional journey"; "A family burden to bear"; "Social connection and disconnection"; and "Tension between visibility and invisibility." From these, two analytical themes were derived: "The emotional challenge of continuing and intensifying adaptation" and "The relational burden of rare disease."

DISCUSSION

The lived experience of pwFSHD is characterized by physical, emotional, and social challenges that impact on engagement with life, particularly as symptoms progress. Further research is needed to provide a fuller understanding of the experience of pain in FSHD and of the lived experience of FSHD across cultures.

A randomised controlled trial of acceptance and commitment therapy for improving quality of life in people with muscle diseases

Abstract.

BACKGROUND

Chronic muscle diseases (MD) are progressive and cause wasting and weakness in muscles and are associated with reduced quality of life (QoL). The ACTMuS trial examined whether Acceptance and Commitment Therapy (ACT) as an adjunct to usual care improved QoL for such patients as compared to usual care alone.

METHODS

This two-arm, randomised, multicentre, parallel design recruited 155 patients with MD (Hospital and Depression Scale ⩾ 8 for depression or ⩾ 8 for anxiety and Montreal Cognitive Assessment ⩾ 21/30). Participants were randomised, using random block sizes, to one of two groups: standard medical care (SMC) (n = 78) or to ACT in addition to SMC (n = 77), and were followed up to 9 weeks. The primary outcome was QoL, assessed by the Individualised Neuromuscular Quality of Life Questionnaire (INQoL), the average of five subscales, at 9-weeks. Trial registration was NCT02810028.

RESULTS

138 people (89.0%) were followed up at 9-weeks. At all three time points, the adjusted group difference favoured the intervention group and was significant with moderate to large effect sizes. Secondary outcomes (mood, functional impairment, aspects of psychological flexibility) also showed significant differences between groups at week 9.

CONCLUSIONS

ACT in addition to usual care was effective in improving QoL and other psychological and social outcomes in patients with MD. A 6 month follow up will determine the extent to which gains are maintained.

Employment status of patients with Charcot-Marie-Tooth type 1A

Previous studies showed that being unemployed is associated with lower quality of life in patients with Charcot-Marie-Tooth type 1A (CMT1A). The aim of this study was to assess the differences between CMT1A patients capable of working and CMT1A patients incapable of working due to CMT1A. Forty-four patients with genetically confirmed CMT1A were included. Medical Research Council (MRC) Sum Score, Charcot-Marie-Tooth Neuropathy Score (CMTNS), CMT Examination Score (CMTES), Overall Neuropathy Limitations Scale (ONLS), Beck Depression Inventory (BDI), Krupp's Fatigue Severity Scale (FSS), and Falls Efficacy Score (FES) were used. Whole cohort was divided into two groups: 1. CMT1A patients capable of working (employed and unemployed not due to CMT) and 2. CMT1A patients incapable of working due to CMT1A (unemployed due to CMT and retired due to CMT). At time of testing, 38.6% patients were employed, 13.6% were unemployed due to CMT, 6.8% were unemployed but not due to CMT, and 40.9% were retired early due to disability caused by CMT. Patients retired due to CMT1A at the age of 43 ± 10 years. ONLS total score and physical work appeared as significant independent predictors of being incapable of working due to CMT1A. Patients incapable of working were almost four times more likely to have fatigue (OR = 3.7, 95% CI 1.0-13.1, p < 0.05) and 11 times more likely to have fear of falling (OR = 11.0, 95% CI 2.0-59.7, p < 0.01). Patients with more severe functional disability and physical type of job were most likely incapable of working due to CMT1A. Incapability of working was associated with fatigue and fear of falling.

Clinical Outcome Evaluations and CBT Response Prediction in Myotonic Dystrophy

BACKGROUND

The European OPTIMISTIC clinical trial has demonstrated a significant, yet heterogenous effect of Cognitive Behavioural Therapy (CBT) for Myotonic Dystrophy type 1 (DM1) patients. One of its remaining aims was the assessment of efficacy and adequacy of clinical outcome measures, including the relatively novel primary trial outcome, the DM1-Activ-c questionnaire.

OBJECTIVES

Assessment of the relationship between the Rasch-built DM1-Activ-c questionnaire and 26 commonly used clinical outcome measurements. Identification of variables associated with CBT response in DM1 patients.

METHODS

Retrospective analysis of the to date largest clinical trial in DM1 (OPTIMISTIC), comprising of 255 genetically confirmed DM1 patients randomized to either standard care or CBT with optionally graded exercise therapy. Correlations of 27 different outcome measures were calculated at baseline (cross-sectional) and of their respective intervention induced changes (longitudinal). Bootstrap enhanced Elastic-Net (BeEN) regression was validated and implemented to select variables associated with CBT response.

RESULTS

In cross-sectional data, DM1-Activ-c correlated significantly with the majority of other outcome measures, including Six Minute Walk Test and Myotonic Dystrophy Health Index. Fewer and weaker significant longitudinal correlations were observed. Nine variables potentially associated with CBT response were identified, including measures of disease severity, executive cognitive functioning and perceived social support.

CONCLUSIONS

The DM1-Activ-c questionnaire appears to be a well suited cross-sectional instrument to assess a variety of clinically relevant dimensions in DM1. Yet, apathy and experienced social support measures were less well captured. CBT response was heterogenous, requiring careful selection of outcome measures for different disease aspects.

The socioeconomic burden of facioscapulohumeral muscular dystrophy

BACKGROUND

Promising genetic therapies are being investigated in facioscapulohumeral muscular dystrophy (FSHD). However, the current cost of illness is largely unknown.

OBJECTIVE

This study aimed at determining the socioeconomic burden of FSHD.

METHODS

Adult patients with FSHD from the Dutch FSHD registry were invited to complete a questionnaire on medical consumption, work productivity and health-related quality of life (HR-QoL) using the EQ-5D-5L. Associated costs were calculated from a societal perspective. A generalized linear model was fitted to the data to investigate whether level of mobility was related to annual costs of illness.

RESULTS

172 patients with FSHD completed the questionnaire (response rate 65%). The per-patient annual direct medical costs of FSHD were estimated at €12,077, direct non-medical costs at €9179 and indirect costs at €5066, adding up to a total cost of illness of €26,322 per patient per year. The direct costs of illness were €21,256, approximately five times higher than the mean per-capita health expenditures in the Netherlands. Major cost-driving factors were formal home care and informal care. A decreased level of mobility was associated with higher direct costs of illness. HR-QoL was significantly reduced in patients with FSHD with a median health utility value of 0.63.

CONCLUSIONS

We show that FSHD is associated with substantial direct and indirect socioeconomic costs as well as a reduction in HR-QoL. These findings are important for health care decision makers and aids in allocation of research funds and evaluation of the cost-effectiveness of novel therapies.

Characterization of individuals with selected muscular dystrophies from the expanded pilot of the Muscular Dystrophy Surveillance, Tracking and Research Network (MD STARnet) in the United States

INTRODUCTION

Data on muscular dystrophies (MDs), a heterogeneous group of heritable diseases hallmarked by progressive muscle deterioration, are scarce.

OBJECTIVE

We describe cross-sectional sociodemographic and clinical characteristics of individuals with congenital, distal, Emery-Dreifuss, facioscapulohumeral, limb-girdle, myotonic, or oculopharyngeal MD.

METHODS

The study was conducted in four sites (Arizona, Colorado, Iowa, and 12 western New York counties) as a pilot expansion of the Muscular Dystrophy Surveillance, Tracking and Research Network, funded by the Centers for Disease Control and Prevention. MDs were detected in healthcare facilities and administrative data sources using International Classification of Disease codes. Our sample contains 1,723 individuals with a MD diagnosis and a healthcare encounter between January 1, 2007 and December 31, 2011.

RESULTS AND CONCLUSIONS

Individuals were mostly non-Hispanic and white. Median ages ranged from 9.2 to 66.0 years. Most (98%) had health insurance. The proportion of individuals who were disabled or unable to work increased with age (range: 8.6-46.4%). People with limb-girdle MD aged ≥18 years were more likely to be nonambulatory (range: 24.5-44.7%). The percentages of individuals with documented clinical interventions during the surveillance period were low. The most common cause of death was respiratory causes (46.3-57.1%); an ICD-10 code for MD (G71.1 or G71.0) was reported for nearly one-half. Our findings show wide variability in sociodemographic and clinical characteristics across MDs.

[Adult myotonic dystrophy type 1: an update]

Myotonic dystrophy type 1 (DM1) or Steinert's disease (CIE-9-C: 359.21; CIE-10-ES: G71.11, ORPHA: 273) is a rare autosomal dominant inherited myopathy with almost complete penetrance and multisystemic consequences (neurological, cardiological, respiratory, endocrinological, and gastrointestinal). It is one of the clinical most variable diseases. The most bothersome symptoms for the patients (mobility problems, fatigue, hypersomnia, or gastrointestinal symptoms) and their families (apathy, lack of initiative) are not necessarily the most dangerous. Respiratory problems and cardiac arrhythmias shorten life expectancy. There is no specific treatment. The role of the Primary Care physician is crucial in the follow-up of DM1, either by coordinating the different professionals or detecting treatable complications. This work addresses the latter.

The Relationship Between Resilience, Self-Efficacy, and Employment in People With Physical Disabilities

The aim of this cross-sectional study was to determine the importance of resilience and self-efficacy in explaining employment status for people with long-term physical disabilities when other sociodemographic and symptom variables were also examined. A multiple logistic regression with sequential predictor entry was used to predict employment status. Participants were individuals, 18 to 65 years of age, with a diagnosis of multiple sclerosis, muscular dystrophy, post-polio syndrome, or spinal cord injury ( N = 882). Results indicated resilience but not self-efficacy was uniquely predictive of employment status. The combined effects of resilience and self-efficacy, however, did not significantly contribute to the variance in employment status above and beyond the sociodemographic and symptom variables. Other variables uniquely predictive of employment included education, age, marital status, disability benefits, and anxiety. We found in this study preliminary evidence to suggest that rehabilitation counseling practitioners should consider a client’s resilience with respect to employment. Knowledge of sociodemographic and symptom factors in conjunction with psychometrically sound measures of resilience and self-efficacy may be used to identify individuals with long-term physical disabilities whose beliefs and behaviors may limit the extent to which they prepare for, obtain, or maintain employment.

Cognitive behavioural therapy with optional graded exercise therapy in patients with severe fatigue with myotonic dystrophy type 1: a multicentre, single-blind, randomised trial

BACKGROUND

Myotonic dystrophy type 1 is the most common form of muscular dystrophy in adults and leads to severe fatigue, substantial physical functional impairment, and restricted social participation. In this study, we aimed to determine whether cognitive behavioural therapy optionally combined with graded exercise compared with standard care alone improved the health status of patients with myotonic dystrophy type 1.

METHODS

We did a multicentre, single-blind, randomised trial, at four neuromuscular referral centres with experience in treating patients with myotonic dystrophy type 1 located in Paris (France), Munich (Germany), Nijmegen (Netherlands), and Newcastle (UK). Eligible participants were patients aged 18 years and older with a confirmed genetic diagnosis of myotonic dystrophy type 1, who were severely fatigued (ie, a score of ≥35 on the checklist-individual strength, subscale fatigue). We randomly assigned participants (1:1) to either cognitive behavioural therapy plus standard care and optional graded exercise or standard care alone. Randomisation was done via a central web-based system, stratified by study site. Cognitive behavioural therapy focused on addressing reduced patient initiative, increasing physical activity, optimising social interaction, regulating sleep-wake patterns, coping with pain, and addressing beliefs about fatigue and myotonic dystrophy type 1. Cognitive behavioural therapy was delivered over a 10-month period in 10-14 sessions. A graded exercise module could be added to cognitive behavioural therapy in Nijmegen and Newcastle. The primary outcome was the 10-month change from baseline in scores on the DM1-Activ-c scale, a measure of capacity for activity and social participation (score range 0-100). Statistical analysis of the primary outcome included all participants for whom data were available, using mixed-effects linear regression models with baseline scores as a covariate. Safety data were presented as descriptives. This trial is registered with ClinicalTrials.gov, number NCT02118779.

FINDINGS

Between April 2, 2014, and May 29, 2015, we randomly assigned 255 patients to treatment: 128 to cognitive behavioural therapy plus standard care and 127 to standard care alone. 33 (26%) of 128 assigned to cognitive behavioural therapy also received the graded exercise module. Follow-up continued until Oct 17, 2016. The DM1-Activ-c score increased from a mean (SD) of 61·22 (17·35) points at baseline to 63·92 (17·41) at month 10 in the cognitive behavioural therapy group (adjusted mean difference 1·53, 95% CI -0·14 to 3·20), and decreased from 63·00 (17·35) to 60·79 (18·49) in the standard care group (-2·02, -4·02 to -0·01), with a mean difference between groups of 3·27 points (95% CI 0·93 to 5·62, p=0·007). 244 adverse events occurred in 65 (51%) patients in the cognitive behavioural therapy group and 155 in 63 (50%) patients in the standard care alone group, the most common of which were falls (155 events in 40 [31%] patients in the cognitive behavioural therapy group and 71 in 33 [26%] patients in the standard care alone group). 24 serious adverse events were recorded in 19 (15%) patients in the cognitive behavioural therapy group and 23 in 15 (12%) patients in the standard care alone group, the most common of which were gastrointestinal and cardiac.

INTERPRETATION

Cognitive behavioural therapy increased the capacity for activity and social participation in patients with myotonic dystrophy type 1 at 10 months. With no curative treatment and few symptomatic treatments, cognitive behavioural therapy could be considered for use in severely fatigued patients with myotonic dystrophy type 1.

Five-year study of quality of life in myotonic dystrophy

Background - Myotonic dystrophy type 1 (DM1) is the most common muscular dystrophy in adults. There is a complete lack of studies that assessed quality of life (QoL) trajectory during time in DM1 cohorts. Aim - To analyze changes of QoL in patients with DM1 during a 5-year follow-up period and to assess responsiveness of the SF-36 questionnaire. Patients and Method - At the baseline, this study comprised 84 DM1 patients, of whom 62 were retested after the mean period of 64.2 ± 3.9 months. Severity of muscular weakness was assessed using the Muscular Impairment Rating Scale (MIRS). Patients completed Serbian version of the SF-36 questionnaire as a measure of health-related QoL. Results - After 5 years, MIRS score of our DM1 patients showed significant progression of 0.5 grade (P < 0.01). All mental subdomains, role physical, and total SF-36 scores significantly improved after 5 years (P < 0.01). Unexpectedly, worsening of muscular weakness from mild to severe was in association with improvement of QoL. Conclusion - QoL improved in our cohort of DM1 patients during a 5-year period despite the progression of the disease. SF-36 should be used with caution as a patient-reported outcome measure in DM1 clinical trials.

Significant impact of behavioral and cognitive impairment on quality of life in patients with myotonic dystrophy type 1

OBJECTIVE

To assess an impact of cognitive and behavioral impairment on QoL in a larger cohort of patients with DM1.

METHODS

Sixty six genetically confirmed DM1 patients (22 with juvenile (jDM1) and 44 with adult form (aDM1) of the disease) were recruited. Following behavioral tests were used: Hamilton scales for depression and anxiety (HamD and HamA), Daytime Sleepiness Scale (DSS), and Krupp's Fatigue Severity Scale (FSS). Patients also underwent detailed classic neuropsychological investigation and Cambridge Neuropsychological Test Automated Battery (CANTAB). Individualized Neuromuscular Quality of Life questionnaire (INQoL) was used as a measure of QoL.

RESULTS

Patients with jDM1 scored lower than aDM1 patients regarding total INQoL score and all INQoL subdomains, except for myotonia. Significant predictors of total INQoL score in patients with jDM1 were severity of fatigue (β=+0.60, p<0.01) and percentage of correct responses on Spatial Recognition Memory test from CANTAB that measures visuospatial abilities (β=-0.38, p<0.05). The most important predictors of total INQoL score in patients with aDM1 were severity of fatigue (β=+0.36, p<0.05) and level of education (β=-0.29, p<0.05).

CONCLUSION

Our results showed clear influence of different central manifestations on QoL in patients with both aDM1 and jDM1.

Professional activity of Emery-Dreifuss muscular dystrophy patients in Poland

OBJECTIVES

Emery-Dreifuss muscular dystrophy (EDMD) is a very rare genetic disorder affecting skeletal and heart muscles. The aim of this study was to identify factors which might influence the ability to work in EDMD patients in Poland.

MATERIAL AND METHODS

The study included 24 patients suffering from either of the two EDMD forms: 17 with emerinopathy (EDMD1; EDMD caused by mutations in the emerin gene) and 7 with laminopathy (EDMD2; EDMD caused by the lamin A/C gene mutations). After clinical evaluation of EDMD course, study participants were questioned about their education, current and former employment, and disability certificates and pensions.

RESULTS

54% of the study participants were employed, and 90% of them had job position corresponding to their education. Undertaking work did not correlate with the level of physical performance or disease complication, but it revealed statistically significant correlation with a higher level of education (p = 0.015). Only 23% of professionally active patients were employed in a sheltered workplace. Disability certificate was granted to all EDMD2 and to 90% of EDMD1 patients. All EDMD2 and 50% of EDMD1 patients received a disability pension, which reflects more severe course of EDMD2.

CONCLUSIONS

Higher level of education increased the chance of employment, even if significant disability was present. Therefore, I hypothesize that advice on education and job counseling should be applied as early as possible after the diagnosis of EDMD.

How persons with a neuromuscular disease perceive employment participation: a qualitative study

INTRODUCTION

A qualitative study was carried out to understand how people with a slow progressive adult type neuromuscular disease (NMD) perceive employment participation.

METHODS

16 paid employed persons with NMD were interviewed in open, in-depth interviews. Data were analyzed using the constant comparison method.

RESULTS

Four themes were identified in the analyses: (1) Experiences regarding the meaning of work; (2) Solving problems oneself; (3) Reaching a turning point; and (4) Taking into account environmental aspects. Persons with NMD highlighted benefits of staying at work as well as the tension they felt how to shape decisions to handle progressive physical hindrances in job retention. This study shows how participants at work with NMD were challenged to keep up appearances at work and at home, the tension felt around when and if to disclose, the effect of their condition on colleagues and work reorganisation challenges. Participants experienced that disclosure did not always make things better. With increasing disability participants' focus shifted from the importance of assistive products towards considerate colleague, in particular superior's willingness in supporting job retention.

CONCLUSIONS

Implications for health professionals might include awareness of the significant impact of changes in physical condition on employment. Timely communication and if appropriate referral to a health or occupational professional may empower employees with NMD to handle employment issues at a for themselves appropriate way. Assistive products and a supportive superior might enhance employment participation.

Clinical, psychosocial, and central correlates of quality of life in myotonic dystrophy type 1 patients

AIMS

To identify sociodemographic, clinical, and central correlates of health-related quality of life (HRQoL) in DM1 patients.

METHODS

200 DM1 patients had assessments of muscular impairment, CTG repeats, and intelligence. Validated instruments were used to assess sociodemographic and clinical factors as well as social support, social participation, daytime sleepiness, fatigue, personality, mood, and quality of life. Regression analysis was used to identify correlates of SF-36 physical and mental component summary scores.

RESULTS

Patients scored lower on all SF-36 physical health subscales compared with normative data but did not differ with respect to mental health function. Regression analysis revealed that psychological distress, fatigue, severe muscular impairment, emotional stability, not having worked within the last 12 months, and lower intellectual quotient were associated with lower scores in physical health function. Moreover, neuroticism, daytime sleepiness, dissatisfaction with social participation, and lower conscientiousness were associated with lower scores in mental health function.

CONCLUSION

DM1 has an impact on SF-36 physical summary scores but not on mental summary scores. Factors such as fatigue, daytime sleepiness, psychological distress, unemployment, and social participation dissatisfaction that significantly affect HRQoL in DM1 are amenable to treatment and psychosocial interventions, namely by providing care that integrate health, social, and community services.

Severe fatigue after kidney transplantation: a highly prevalent, disabling and multifactorial symptom

Fatigue is a common symptom of patients with chronic kidney disease, but seldom investigated after transplantation. We determined the prevalence, impact and related factors of severe fatigue in kidney transplant recipients (KTRs). Medical records and questionnaires were used to assess kidney function, donor characteristics, fatigue (Checklist Individual Strength), functional impairments (Sickness Impact Profile), work status, body mass index (BMI), pain, depressive symptoms, social support and sleeping problems in 180 participating KTRs. KTRs were compared with sex- and age-matched population-based controls. KTRs were significantly more often severely fatigued (39%) compared to matched controls (22%; P = 0.001). Severely fatigued KTRs had significantly more functional impairments than nonseverely fatigued recipients (effect size ≥ 0.7) P < 0.001, and less often a paid job (27% vs. 48%, P = 0.005). Univariate analysis showed that severely fatigued KTRs received more often a kidney from a deceased donor, had a higher BMI, more pain, discrepancy in social support, depressive symptoms and sleeping problems. In a multivariate analysis (n = 151) the latter two associations remained significant. Severe fatigue is a highly prevalent and disabling symptom in KTRs. Moreover, severe fatigue after kidney transplantation is more strongly related to behavioural and psychosocial factors than specific transplantation-related factors. Findings have implications for fatigue management.

Challenge of transition in the socio-professional insertion of youngsters with neurodisabilities

OBJECTIVE

To evaluate the activities of patients with neurodisabilities and assess their insertion problems in the professional world.

METHODS

It is based on medical records of 267 patients (224 with neurodevelopmental diseases and 43 with neuromuscular diseases), aged 16-25 years, followed in the transition clinic of young adults in the neurorehabilitation services of a tertiary center.

RESULTS

Nearly half of them (46.8%) were in a protected environment, 37.08% studied and only 3.4% worked. Their studies are much longer and they are less in university than Swiss people of same age. The competitiveness criteria are no mental retardation and to be completely independent. Finally, 29.2% reported work problems, the foremost being the lack of adaptation in the workplace.

CONCLUSION

These results highlight the need to increase the integration of young adults with neuromotor disorders in the labor market.

Patient-identified disease burden in facioscapulohumeral muscular dystrophy

INTRODUCTION

The multitude of symptoms associated with facioscapulohumeral muscular dystrophy (FSHD) disease burden are of varying importance. The extent of these symptoms and their cumulative effect on the FSHD population is unknown.

METHODS

We conducted interviews with adult FSHD patients to identify which symptoms have the greatest effect on their lives. Each interview was recorded, transcribed, coded, and analyzed using a qualitative framework technique, triangulation, and a three-investigator consensus approach.

RESULTS

One thousand three hundred seventy-five quotes were obtained through 20 patient interviews. Two hundred fifty-one symptoms of importance were identified representing 14 themes of FSHD disease burden. Symptoms associated with mobility impairment, activity limitation, and social role limitation were most frequently mentioned by participants.

CONCLUSIONS

There are multiple themes and symptoms, some previously underrecognized, that play a key role in FSHD disease burden.

Research priorities of patients with neuromuscular disease

PURPOSE

This paper describes a study in which patients with neuromuscular disease (NMD) were engaged to list top-priorities for scientific research in order to complement the researchers' agenda.

METHOD

A dialogic model for research agenda setting was used. Interviews, focus groups and expert meetings with patients were held to identify research topics. Research topics were prioritized via a questionnaire. Agendas were integrated in a dialogue meeting with professionals and patients.

RESULTS

The research agenda of NMD patients is divided in four research domains, with a total of 24 research topics. These domains include (1) health; (2) quality of life; (3)quality of care and support, and (4) basic issues. Among the research domains highest priority was given to research on health, followed by research on quality of life.

CONCLUSIONS

Both patients and professionals agreed a proper balance needs to be found between fundamental research and research on symptomatic treatment and quality of life. They concluded that more attention is required for research on the effective treatment of symptoms, quality of life and implementation of knowledge about NMD in regular care.

Influence of multisystemic affection on health-related quality of life in patients with myotonic dystrophy type 1

AIM

To assess health-related quality of life (HRQoL) in patients with DM1, to identify muscular, multisystemic, central and social factors that may affect QoL and to define a DM1 patient in risk of poor QoL.

PATIENTS AND METHOD

This cross-sectional study comprised 120 DM1 consecutive patients. The following scales were used: Multidimensional Scale of Perceived Social Support (MSPSS), Muscular Impairment Rating Scale (MIRS), battery of neuropsychological tests, acceptance of illness scale (AIS), Hamilton rating scale for depression (Ham-D), Krupp's Fatigue Severity Scale (FSS), Daytime Sleepiness Scale (DSS) and SF-36 questionnaire.

RESULTS

HRQoL was impaired in DM1 patients in both physical and mental domains (PCS was 41.8±23.5, MCS 47.0±24.3 and total SF-36 score 45.6±24.0). The most significant factors correlating with better SF-36 total score were younger age (β=-0.45, p<0.001), shorter duration of disease (β=-0.27, p=0.001), higher education (β=0.20, p=0.009), less severe muscular weakness (β=-0.52, p<0.001), normal swallowing (β=0.22, p=0.005), absence of fainting (β=0.31, p=0.002), absence of snoring (β=0.21, p=0.036), better acceptance of disease (β=-0.17, p=0.036), lower depressiveness (β=-0.46, p=0.001), lower fatigue (β=-0.32, p=0.001), absence of cataract (β=-0.21, p=0.034), absence of kyphosis (β=0.31, p=0.004) and absence of constipation (β=0.24, p=0.016). Second linear regression analysis revealed that depressed (β=-0.38, p<0.001) and elder patients (β=-0.27, p=0.007) and as well as those with poor acceptance of illness (β=-0.21, p=0.006) were in especially higher risk of having poor HRQoL (R(2)=0.68).

CONCLUSION

We identified different central, social, muscular, cardiorespiratory and other factors correlating with HRQoL. It is of great importance that most of these factors are amenable to treatment.

Exploring employment in consultation reports of patients with neuromuscular diseases

OBJECTIVES

To explore consultation reports for patient and employment characteristics and recommendations on employment regarding patients with neuromuscular diseases (NMDs).

DESIGN

Retrospective study of multidisciplinary reports.

SETTING

An outpatient neuromuscular clinic at a university hospital.

PARTICIPANTS

Reports (N=102) of patients with NMDs.

INTERVENTIONS

Based on one-off consultations by occupational therapists, physical therapists, and speech therapists and a multidisciplinary meeting, recommendations were developed regarding therapy content and volume in primary care or rehabilitation settings.

MAIN OUTCOME MEASURES

A checklist has been developed to examine employment characteristics. A general questionnaire has been used including demographic variables and data on employment.

RESULTS

Of the 102 reports available, 86 were included for analysis. Sixty-nine reports contained information on employment. Thirty-seven patients (43%) with NMD were employed, most in white-collar or moderately strenuous jobs. Of the 37 employed patients, 28 (76%) worked using adaptations. Thirty-two (87%) had employment problems; of these, 15 (40%) needed improvement in 1 or more environmental factors. Twenty patients (54%) needed advice regarding participation in employment, of whom 19 were referred to primary care or rehabilitation settings for treatment to enhance employment participation.

CONCLUSIONS

Eighty percent of the included consultation reports contained information on employment. Less than half the patients with NMD were employed, most in office-related jobs, using some kind of adaptations. Nineteen of 20 patients who agreed to recommendations regarding therapy were adequately referred by occupational therapists and physical therapists for treatment of employment problems.

A systematic review of quality of life in adults with muscle disease

We reviewed the literature on how muscle disease affects quality of life compared to healthy controls, and the factors that influence the effects of muscle disease on quality of life. We also wanted to know whether quality of life differed between muscle diseases. We searched online databases and identified 26 relevant studies. The quality of each study was assessed, results sections analysed and a database of factors associated with quality of life developed. We graded the level of evidence supporting the association between each factor and quality of life as inconclusive, moderate or high. Compared to controls, muscle disease compromised quality of life in all areas of functioning. There was little evidence to suggest that quality of life differed significantly between muscle diseases. There was a high level of evidence suggesting that disease severity, pain, fatigue, and mood significantly affect quality of life. There was a moderate level of evidence suggesting that illness perceptions, coping strategies, age and gender affect quality of life. Several factors had an inconsistent level of evidence.
