Workers with disability: the case of multiple sclerosis

Identifying key determinants of work-related difficulties in multiple sclerosis: integrating clinical measures and socio-occupational factors

BACKGROUND

One of the most social consequences of Multiple Sclerosis (MS) is a reduction in employability that occurs early in the disease. The aim of the study is to explore the factors contributing to specific work-related difficulties, including main functions affected by MS.

METHODS

The study involved two Italian centers and included subjects with MS diagnosis of working age (18-65 years) and currently employed. Subjects underwent an evaluation to investigate work-related difficulties, socio-occupational data and the main clinical domain affected by MS with an impact on work-related difficulties, such as walking, balance, upper limb and cognitive functions, mood and fatigue. Linear regression analysis was used to examine the direction and size of the relationships between specific work-related difficulty and the variables examined.

RESULTS

A total of 82 subjects with MS were recruited (59.8% of females, mean age 44.0 (SD: 10.7) years, a mean EDSS score of 3.7 (SD: 2.4); mean education of 15.2 (SD: 4.2) years). The 36.6% of the sample resulted having work-related difficulties with a possible consequent risk of job lost. Our results highlighted that objective assessment of walking and balance, upper limb and cognitive functions were not significant determinants of any specific work-related difficulties. However, the key factors most strongly associated with work challenges are the presence of depressive symptoms, followed by physical and cognitive fatigue.

CONCLUSION

Identifying the main factors related to work difficulties is a fundamental step to prevent the manifestation of these difficulties and develop tailored intervention for job retention.

Work Difficulties in People with Multiple Sclerosis

PURPOSE

This study identifies potential predictors of unemployment and describes specific work difficulties and their determinants in a subgroup of employed people with multiple sclerosis (PwMS). The specific work difficulties were evaluated using a validated tool that measures the impact of respondents' symptoms and of workplace features.

METHODS

A cross-sectional study was carried out in Italy during 2021-2022. The subjects included were adults (18-65 years) with a diagnosis of MS, currently employed or unemployed. Logistic regression models were used to determine the association between each potential determinant and employment status, while linear regression models were used to determine the association between determinants and specific work difficulties.

RESULTS

The main risk factors associated with a higher risk of being unemployed were being older, living in the South of Italy/islands, and having a higher disability level, while protective factors against unemployment were having a high level of education and 'stable' employment (an open-ended contract). Fatigue was found to be associated with all work difficulties analyzed; mood disorders emerged as the main predictors of mental health-related work difficulties; level of disability and comorbidity significantly impacted physical health-related ones, and a good quality of life was found to improve both workplace-related and mental health-related difficulties at work.

CONCLUSION

Identifying the most significant difficulties is a crucial step in the development of vocational rehabilitation interventions tailored to maximize the ability of PwMS to handle their job-related duties and demands.

Factors associated with requesting accommodations among people with multiple sclerosis

BACKGROUND

Almost one million individuals are living with multiple sclerosis (MS) in the United States with a majority being diagnosed when they are in their 20s or early stages of their careers. Employees with MS experience various job-related challenges such as high unemployment and underemployment. Accommodations assist individuals with MS to obtain and maintain employment, yet the current understanding of factors affecting decisions to request or withhold accommodations is limited.

OBJECTIVE

This study aimed to explore barriers and facilitators of workplace accommodation requests among individuals with MS through a qualitative approach.

METHODS

Eighty-six participants were recruited from agencies serving individuals with MS in the US. Content analysis was conducted to examine responses to one open-ended question related to their perception of barriers or facilitative strategies to request accommodations.

RESULTS

Ten overarching themes related to barriers and facilitators for requesting accommodations were identified. Among them were three facilitators (i.e., positive work environment, employer compliance and flexibility, and employee self-advocacy and proactivity) and seven barriers (i.e., employers' lack of knowledge of Americans with Disabilities Act and accommodations, employers' discrimination and resistance to accommodation requests, employees' fear/anxiety to request due to associated stigma, employees' lack of knowledge about accommodations/disability/resources as well as inaccessible workspace).

CONCLUSIONS

Rehabilitation professionals can educate and empower employees with MS to disclose disability and request needed accommodations. Rehabilitation professionals also can educate employers for individuals with MS about their obligations under the laws to provide accommodations and sensitize coworkers of individuals with MS regarding the disability.

Disabled in Society - A Scoping Review on Persons Living with Multiple Sclerosis and Disability

Multiple sclerosis (MS) is a chronic neurological disease with an increasing prevalence. As such, most studies are devoted to various medical aspects of the disease. The theoretical framework used in this scoping review was the social model of disability - a perspective focusing on environmental barriers and discrimination that disabled people face in society. The aim was to explore previous research on disabling barriers and discrimination against persons with MS, and to identify research gaps in connection with this population. The scoping review was performed in two steps: (1) a main search in 8 databases, followed by (2) citation and reference searches. The final sample consisted of 96 included articles. The result showed that most studies had been conducted in the US, and the dominant area of research was employment discrimination. Previous research has studied MS related to various areas, such as employment, social welfare and social services, transportation, housing and accessibility of public places, health services, and in relation to others within society. However, this scoping review showed that although several areas of disability and MS had been included in the previous research, most of the identified areas were researched in few studies without the possibility to generalize the findings to a larger population or a cross-cultural context. Few studies compared differences between persons with MS based on gender, age, and ethnicity. What impact the invisible symptoms of MS had on disability was also researched to a limited extent. The findings have implications for future research and clinical practice. To better understand living conditions for persons with MS from a global perspective, more research across countries is needed. Healthcare professionals need to assess the individual's situation regarding both symptoms of the disease and the impact of societal barriers and discrimination to optimize care of persons with MS.

Return on Investment (ROI) and Development of a Workplace Disability Management Program in a Hospital-A Pilot Evaluation Study

The progressive ageing of the working population and the increase in related chronic diseases tend to affect working capacity. The aim of this study was to evaluate a Workplace Disability Management Program (WDMP) within a pediatric hospital. Absenteeism due to healthcare workers’ (HCWs) pre- and post- WDMP and the related costs were used for the program evaluation. The Return on Investment (ROI), the Break-Even Analysis (BEA) and the value of the average annual productivity of HCWs who took advantage of the Disability Management (DM) interventions to assess the economic impact of the program, were also used. The HCWs enrolled in the program were 131 (approximately 4% of hospital staff), of which 89.7% females and with an average age of 50.4 years (SD ± 8.99). Sick leave days of the HCWs involved decreased by 66.6% in the year following the end of WDMP compared to the previous one (p < 0.001). The total estimated cost reduction of absenteeism is 427,896€ over a year. ROI was equal to 27.66€. BEA indicated that the break-even point was reached by implementing the program on 3.27 HCWs. The program evaluation demonstrated the particular effectiveness of the implemented WDMP model, acting positively on the variables that affect productivity and the limitation to work.

Targeting Phosphodiesterases-Towards a Tailor-Made Approach in Multiple Sclerosis Treatment

Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system (CNS) characterized by heterogeneous clinical symptoms including gradual muscle weakness, fatigue, and cognitive impairment. The disease course of MS can be classified into a relapsing-remitting (RR) phase defined by periods of neurological disabilities, and a progressive phase where neurological decline is persistent. Pathologically, MS is defined by a destructive immunological and neuro-degenerative interplay. Current treatments largely target the inflammatory processes and slow disease progression at best. Therefore, there is an urgent need to develop next-generation therapeutic strategies that target both neuroinflammatory and degenerative processes. It has been shown that elevating second messengers (cAMP and cGMP) is important for controlling inflammatory damage and inducing CNS repair. Phosphodiesterases (PDEs) have been studied extensively in a wide range of disorders as they breakdown these second messengers, rendering them crucial regulators. In this review, we provide an overview of the role of PDE inhibition in limiting pathological inflammation and stimulating regenerative processes in MS.

Improving the job-retention strategies in multiple sclerosis workers: the role of occupational physicians

Several studies evaluated whether a person with multiple sclerosis is employed or not and investigated the main symptoms that hinder the job performance. However, despite occupational physicians are fundamental in managing disabled subjects, there is a serious lack of data regarding their role in improving employability of these workers. In this regard, we assessed occupational physicians' professional activity and training/updating needs in order to identify and develop management tools, operative procedures and training programs helpful to support and implement adequate job-retention strategies. Four hundred three Italian occupational physicians compiled a self-administered questionnaire to evaluate individual demographics, health surveillance system, fitness for work and training needs. Our findings confirmed the suitability to adopt environmental adjustments at workplace (particularly referring to the ergonomics of workstation, the typology of occupational risk factors and the working time) to accommodate individual's needs in order to improve working ability among multiple sclerosis workers. Moreover, training events discussing operational guidelines and standardized instruments and/or methodologies to adequately manage the disable workers should be fostered. Therefore, in this regard, occupational physicians could play a key role but they need more high-quality training especially concerning the different tools that are currently available to assess the work issues in multiple sclerosis patients.

Treatment Patterns, Healthcare Resource Utilization, and Costs Among Medicare Patients with Multiple Sclerosis in Relation to Disease-Modifying Therapy and Corticosteroid Treatment

INTRODUCTION

Despite the increasing age of the multiple sclerosis (MS) patient population, data are lacking on MS patients in later life. This retrospective study investigated treatment patterns, healthcare resource utilization (HCRU), and healthcare costs (HCCs) for patients enrolled in Medicare, in relation to disease-modifying therapy (DMT) and corticosteroid treatment as a marker for relapse.

METHODS

Medical and pharmacy claims between January 1, 2010 and July 31, 2015 identified MS patients. The anchor date was defined as the most recent MS claim. Analyses were performed on claims in the 12-month baseline period before the anchor date. Outcomes were stratified by DMT use and number (0, 1, or ≥ 2) of corticosteroid treatments.

RESULTS

Among Medicare MS patients (n = 7072; mean age 57 years), 66% received DMT during the baseline period; 31% had 1 claim and 16% had ≥ 2 claims for corticosteroids. Compared with patients not receiving DMT, patients on DMT were less likely to receive corticosteroids (39% vs 62%) and had fewer all-cause hospitalization episodes and ER visits. DMT use was associated with lower HCRU but higher HCCs in patients both with and without corticosteroid treatment. DMT switching rates were low, both among patients with no corticosteroid (5.6%) and patients with 1 (9.3%) or ≥ 2 (11.1%) corticosteroid treatments. DMT switches were most frequently from an injectable to an oral therapy.

CONCLUSION

In Medicare patients with MS, DMT use was associated with higher HCCs but lower HCRU, indicative of better health outcomes; however, low DMT switching rates may be an indicator of possible clinical inertia.

Older age, higher perceived disability and depressive symptoms predict the amount and severity of work-related difficulties in persons with multiple sclerosis

Purpose: This cross-sectional study aims to identify the predictors of work-related difficulties in a sample of employed persons with multiple sclerosis as addressed with the Multiple Sclerosis Questionnaire for Job Difficulties. Materials and methods: Hierarchical linear regression analysis was conducted to identify predictors of work difficulties: predictors included demographic variables (age, formal education), disease duration and severity, perceived disability and psychological variables (cognitive dysfunction, depression and anxiety). The targets were the questionnaire's overall score and its six subscales. Results: A total of 177 participants (108 females, aged 21-63) were recruited. Age, perceived disability and depression were direct and significant predictors of the questionnaire total score, and the final model explained 43.7% of its variation. The models built on the questionnaire's subscales show that perceived disability and depression were direct and significant predictors of most of its subscales. Conclusions: Our results show that, among patients with multiple sclerosis, those who were older, with higher perceived disability and higher depression symptoms have more and more severe work-related difficulties. The Multiple Sclerosis Questionnaire for Job Difficulties can be fruitfully exploited to plan tailored actions to limit the likelihood of near-future job loss in persons of working age with multiple sclerosis. Implications for rehabilitation Difficulties with work are common among people with multiple sclerosis and are usually addressed in terms of unemployment or job loss. The Multiple Sclerosis Questionnaire for Job Difficulties is a disease-specific questionnaire developed to address the amount and severity of work-related difficulties. We found that work-related difficulties were associated to older age, higher perceived disability and depressive symptoms. Mental health issues and perceived disability should be consistently included in future research targeting work-related difficulties.

Employment and multiple sclerosis: A meta-analytic review of psychological correlates

The association between employment and psychological health in adults with multiple sclerosis was examined ( N = 33 studies). Standardised mean differences (Hedges’ g) between those employed and those not in the workforce were calculated. Employed peers reported significantly greater quality of life and mood, cited fewer work and multiple sclerosis–related difficulties and were more likely to adopt problem-focused coping strategies, considered to be more effective in managing specific stressors. These data are consistent with the positive by-products of maintaining work with multiple sclerosis. Further research is needed to determine the longitudinal course of coping for those who remain employed.

Variants of MicroRNA Genes: Gender-Specific Associations with Multiple Sclerosis Risk and Severity

Multiple sclerosis (MS) is an autoimmune neuro-inflammatory disease arising from complex interactions of genetic, epigenetic, and environmental factors. Variations in genes of some microRNAs--key post-transcriptional regulators of many genes--can influence microRNAs expression/function and contribute to MS via expression changes of protein-coding target mRNA genes. We performed an association study of polymorphous variants of MIR146A rs2910164, MIR196A2 rs11614913, MIR499A rs3746444 MIR223 rs1044165 and their combinations with MS risk and severity. 561 unrelated patients with bout-onset MS and 441 healthy volunteers were enrolled in the study. We observed associations of MS risk with allele MIR223*T and combination (MIR223*T + MIR146A*G/G) carriage in the entire groups and in women at Bonferroni-corrected significance level (pcorr < 0.05). Besides, MIR146A*G/G association with MS was observed in women with nominal significance (pf = 0.025). No MS associations were found in men. A more severe MS course (MSSS value > 3.5) was associated with the carriage of MIR499A*C/T and, less reliably, of MIR499A*C (pcorr = 0.006 and pcorr = 0.024, respectively) and with the carriage of combinations (MIR499A*C/T + MIR196A2*C) and (MIR499A*C + MIR196A2*C) (pcorr = 0.00078 and pcorr = 0.0059, respectively). These associations also showed gender specificity, as they were not significant in men and substantially reinforced in women. The strongest association with MS severity was observed in women for combination (MIR499A*C/T + MIR196A2*C): pcorr = 4.43 × 10(-6) and OR = 3.23 (CI: 1.99-5.26).
