Unacceptable Work State in Rheumatoid Arthritis: Establishment of Thresholds for Presenteeism and Clinical Measurement Instruments

OBJECTIVE

We aimed to identify threshold values of presenteeism measurement instruments that reflect unacceptable work state in employed patients with rheumatoid arthritis (RA) and whether those thresholds can predict future adverse work outcomes (AWOs). Additionally, we assessed the performance of presenteeism thresholds previously established in axial spondyloarthritis (axSpA) among patients with RA for the same instruments.

METHODS

Data from the multinational Patient-Reported Outcomes in Employment Study in Rheumatoid Arthritis (RA-PROSE) study were used. Thresholds to determine when patients consider themselves in an "unacceptable work state" were calculated at baseline for 4 instruments assessing presenteeism and for the patient global assessment of RA-related pain. Different approaches derived from the receiver-operating characteristic methodology were used. Accuracy of thresholds to predict AWO throughout 12 months was assessed and previously developed presenteeism thresholds for axSpA were also tested.

RESULTS

A total of 104 employed patients were included: 15% of the patients considered themselves in an unacceptable work state, of which 7 (7%) had at least 1 AWO over 12 months. Thresholds of all instruments specifically developed in RA showed good performance vs the external criterion (area under the curve [AUC] > 0.75), except for the Quantity and Quality (QQ) method (AUC 0.62). The available axSpA thresholds were more accurate by reducing overestimation. The final optimal thresholds were Work Productivity and Activity Impairment Questionnaire (WPAI)-presenteeism ≥ 40, QQ method < 97, Workplace Activity Limitations Scale ≥ 0.75, 25-item Work Limitations Questionnaire with modified physical demands scale ≥ 29, and pain intensity ≥ 4. For AWO over 12 months, pain and WPAI performed best in predicting AWO.

CONCLUSION

The final thresholds to assess unacceptable presenteeism for axSpA were also chosen as most accurate for use in RA. In addition, accurate thresholds of pain reflecting unacceptable work state are available.

The Job Demands and Accommodation Planning Tool (JDAPT): A Nine-Month Evaluation of Use, Changes in Self-efficacy, Presenteeism, and Absenteeism in Workers with Chronic and Episodic Disabilities

PURPOSE

Enhancing workplace communication and support processes to enable individuals living with disabilities to sustain employment and return to work is a priority for workers, employers, and community stakeholders. The objective of this study was to evaluate a new resource that addresses support challenges, the Job Demands and Accommodation Planning Tool (JDAPT), and assess its use, relevance, and outcomes over a nine-month follow-up period.

METHODS

Workers with physical and mental health/cognitive conditions causing limitations at work were recruited using purposive sampling. Online surveys were administered at baseline (prior to using the JDAPT), and at three and nine months post-baseline. Information was collected on demographics (e.g., age, gender) and work characteristics (e.g., job sector, organization size). Outcomes included assessing JDAPT use and relevance, and changes in self-efficacy, work productivity difficulties, employment concerns, difficulties with job demands, and absenteeism.

RESULTS

Baseline participants were 269 workers (66% women; mean age 41 years) of whom 188 (69.9%) completed all three waves of data collection. Many workers reported using JDAPT strategies at and outside of work, and held positive perceptions of the tool's usability, relevance, and helpfulness. There were significant improvements (Time 1-2; Time 1-3) in self-efficacy, perceived work productivity, and absenteeism with moderate to large effect sizes in self-efficacy and productivity (0.46 to 0.78). Findings were consistent across gender, age, health condition, and work context variables.

CONCLUSIONS

The JDAPT can enhance support provision and provide greater transparency and consistency to workplace disability practices, which is critical to creating more inclusive and accessible employment opportunities.

The management of axial spondyloarthritis with cutting-edge therapies: advancements and innovations

INTRODUCTION

Axial involvement in spondyloarthritis has significantly evolved from the original 1984 New York criteria for ankylosing spondylitis, leading to an improved understanding of axial spondyloarthritis (axSpA) as a disease continuum encompassing non- radiographic axSpA (nr-axSpA) and radiographic axSpA (r-axSpA). A clear definition for early axSpA has been established, underscoring the need for early intervention with biological and targeted synthetic drugs to mitigate pain, reduce functional impairment, and prevent radiographic progression.

AREAS COVERED

This review explores therapeutic strategies in axSpA management, focusing on biological and targeted synthetic therapies and recent advancements. Biologics targeting TNFα or IL-17 and targeted synthetic disease-modifying antirheumatic drugs (DMARDs) are primary treatment options. These therapies significantly impact clinical outcomes, radiographic progression, and patient-reported functional improvement.

EXPERT OPINION

AxSpA treatment has evolved significantly, offering various therapeutic options. Biological DMARDs, particularly TNFα inhibitors, have transformed treatment, significantly enhancing patient outcomes. However, challenges persist for patients unresponsive or intolerant to existing therapies. Emerging therapeutic targets promise to address these challenges. Comprehensive management strategies and personalized approaches, considering extra-articular manifestations and individual patient factors, are crucial for achieving optimal outcomes in axSpA management.

Impact of Chronic Spontaneous or Inducible Urticaria on Occupational Activity

The impact of chronic urticaria on work has been scarcely reported, whereas its peak incidence is between the ages of 20 and 40. The aim of this study was to assess the occupational impact of chronic urticaria and its treatment, by combining objective and patient-reported data. A monocentric observational study was performed using questionnaires over a 1-year period from 2021 to 2022 in chronic urticaria patients who were in a period of professional activity and agreed to participate. Of the 88 patients included, 55.7% assessed the occupational impact of their chronic urticaria as significant, and even more severe when chronic urticaria was poorly controlled. Some 86% of patients had symptoms at work, in a third of cases aggravated by work. However, occupational physical factors were not associated with an aggravation of inducible chronic urticaria. A total of 20% reported treatment-related adverse effects affecting their work. Despite low absenteeism, presenteeism and reduced productivity were important (> 20%). Six patients (6.8%) had difficulties keeping their work. For 72.7% of the patients, the occupational physician was not informed. The occupational impact of chronic urticaria should be discussed during consultations, particularly when it is insufficiently controlled. The occupational physician should be informed in order to support patients' professional project.

Improvement in patient-reported outcomes and work productivity following 3-year ustekinumab or tumour necrosis factor inhibitor treatment in patients with psoriatic arthritis: results from the PsABio real-world study

BACKGROUND

To evaluate the real-world effect of the IL-12/23 inhibitor ustekinumab or of a tumour necrosis factor inhibitor (TNFi) on patient-reported outcomes (PRO) and their association with effectiveness endpoints in psoriatic arthritis (PsA) patients over 3 years.

METHODS

In PsABio (NCT02627768), a prospective, observational study, patients with PsA that were prescribed first- to third-line ustekinumab or a TNFi, and remained on that drug for 3 years, were analysed for change in baseline in PROs (EuroQol-5 dimensions health state VAS [EQ-5D VAS], 12-item Psoriatic Arthritis Impact of Disease questionnaire [PsAID-12; range 0-10], Work Productivity and Activity Impairment for Psoriatic Arthritis questionnaire [WPAI; results expressed as a percentage for each domain]), and the association between PROs and WPAI with effectiveness endpoints, clinical disease activity index for psoriatic arthritis (cDAPSA), low disease activity (LDA)/remission, minimal disease activity (MDA) and very low disease activity (VLDA).

RESULTS

In 437 patients (mean age 49.1 years, 47.8% female), at 3 years, ustekinumab and TNFi treatment led to comparable improvements in EQ-5D VAS; mean change from baseline (95% confidence intervals [CI]) was 11.0 (6.5; 15.4) and 18.9 (14.0; 23.9), respectively. Both groups improved PsAID-12 after 3 years; mean change from baseline (95% CI) was -2.9 (-3.2; -2.5) and -3.5 (-3.9; -3.2), respectively. At baseline, due to their PsA, TNFi-treated patients had lower work productivity compared to ustekinumab-treated patients; mean productivity reduction (95% CI) was 58.8 [52.4; 65.2] and 43.3 [35.6; 51.1]. Over 3 years, TNFi-treated patients had a greater improvement in work productivity compared to ustekinumab-treated patients, ultimately leaving work productivity to be comparable between groups; mean improvement (95% CI) was 44.5% (38.4; 50.6) and 24.9% (15.8; 34.0), respectively. A similar trend was observed in activity impairment. Patients in both treatment groups who achieved effectiveness endpoints, cDAPSA LDA/remission, MDA, and VLDA had greater improvement in PROs and WPAI than patients who did not achieve these endpoints.

CONCLUSIONS

At 3 years, improvements in PROs following ustekinumab or TNFi treatment were generally comparable; however, TNFi-treated patients achieved a greater improvement in work productivity, although this group started from a lower baseline. Achievement of effectiveness endpoints, independent of treatment group, also improved PROs.

A 5 item version of the Workplace Activity Limitation Scale successfully identifies impaired work productivity in rheumatoid arthritis patients: A split-sample factor analysis approach

BACKGROUND

There is a growing interest in studying the effects of arthritis on a person's work productivity using a growing variety of outcome indicators.

OBJECTIVES

To develop a valid and reliable shortened version of the Workplace Activity Limitation Scale 12 (WALS-12) for assessing work productivity limitations in rheumatoid arthritis (RA) patients.

METHODS

A cross-sectional study involving 277 RA patients was conducted. An exploratory factor analysis on WALS-12 was used for item reduction on the first sample. Then confirmatory factor analysis (CFA) was run to establish the best fit indices of the reduced version. On the second sample, CFA and linear discriminant analysis were performed to assess the diagnostic performance and discriminant ability of the reduced form. A Bland-Altman method was used to find the agreement between the WALS-12 and the reduced one.

RESULTS

The WALS-12 was reduced to 5 items. The Cronbach α was 0.817, with a composite reliability of 0.715. The Spearman rho correlation coefficient ranged between 0.675 and 0.795 for WALS-5, which was higher for the scale items with their domains than the correlation of WALS-5 with the domains of Work Limitations Questionnaire-25. Also, the root square of the average variant extracted from WALS-5 was 0.802. WALS-5 showed excellent discriminant ability with an area under the curve of 0.98 (P < .001), sensitivity of 97%, specificity of 82%, and accuracy of 94%. The reduced version WALS-5 was in agreement with the original version WALS-12.

CONCLUSIONS

WALS-5 is a valid and reliable tool to assess the work productivity limitations in RA patients.

A New Instrument for Assessing Work-Related Body Mechanics and Strain in the General Population

Clinical pain is often linked to poor body mechanics, with individuals sometimes presenting multiple painful disorders. Such disorders may be influenced by behaviors that affect the general resiliency and health of the musculoskeletal system. We aimed to develop a self-reported scale using the Malmö Diet and Cancer Study questions on work-related body mechanical exposures. An expert panel identified 41 variables having content validity for musculoskeletal problems. Exploratory factor analysis was conducted on a random selection of 50% of the cohort (n = 6,789 adults); the remaining was reserved for confirmatory factor analyses (CFA), item response theory (IRT) item calibration, and differential item functioning investigations. Supported by standard measure development methods and fit criteria, the final unidimensional item bank contains 13 items. Overall CFA statistics (root mean square error of approximation = .09; comparative fit index = .96; Tucker-Lewis index = .96; standardized root mean residuals = .05) indicated excellent single-factor model fit and appropriateness of IRT modeling and calibration. Expert review and item information values (score-precision) guided selection of an 8-item short form with acceptable score-level reliabilities (≥.70) for T-scores = 39-80+. This measure provides reliable assessment of body mechanics strain in adults and can be useful when evaluating different contributions to musculoskeletal problems affecting pain-treatment success in future clinical research. PERSPECTIVE: This article presents the development and psychometric properties of a new measure, "Work-related Body Mechanics and Strain Scale (WR-BMSS)." The scale has 13-items or alternatively an 8-item short form. This measure could potentially help clinicians who seek to assess how musculoskeletal problems may contribute to patient pain and disability.

Linking job duties, functioning, and employment status using the Work-Disability Functional Assessment Battery (WD-FAB): An expert coding and quantitative analysis

BACKGROUND

An understanding of the link between specific occupational demands and individual worker functioning is limited, although such information could permit an assessment of the fit between the two in a manner that would inform national and state disability programs such as vocational rehabilitation and Social Security disability programs.

OBJECTIVE

Our goal was to examine the utility of assessing physical and mental functioning relative to self-reported job duties to identify the domains of worker functioning most likely to create barriers to fulfilling an occupation's specific requirements.

METHODS

Through primary survey data collection, 1770 participants completed the Work-Disability Functional Assessment Battery (WD-FAB) instrument after reporting details on their occupations (or most recent occupation if not working). Expert coders evaluated the level of function expected to successfully carry out each self-reported job duty with respect to six scales of physical and mental function. Quantitative analysis is used to examine the relationship between functioning and job duties.

RESULTS

Those not working due to disability were more likely to fall short of the threshold of the physical and mental functioning requirements of their last job's three main job duties compared to those currently employed. Mental function scales were most likely to be the area experiencing a shortfall.

CONCLUSIONS

Functional difficulties impede the ability to continue working in particular jobs that require that ability. This points to a need for specific accommodations to be implemented to bridge the gap between job requirements and functional capacity so that workers may remain engaged in their current work.

Workplace activity limitation and quality of life: A study on rheumatoid arthritis patients

BACKGROUND: Rheumatoid arthritis (RA) causes disabilities that affect people in working age and can impair their working activity and quality of life (QoL). OBJECTIVES: To assess work activity limitation and QoL among RA patients and to explore the associated risk factors. METHODS: A cross-sectional study on 344 RA patients was conducted at the outpatient clinic using a number of standardized questionnaires including the Health Assessment Questionnaire Disability Index, Workplace Activity Limitation Scale, and RA QoL. Clinical examinations were also performed including the measurement of pain intensity, assessment of disease activity, and the Rheumatoid Arthritis Severity Scale. RESULTS: Most of the employed participants (87%) experienced high work activity limitations. Increasing work limitations were significantly associated with a decrease in QoL domains scores. The most significant risk factors affecting work limitation by logistic regression were high disease activity, the severity of the disease, married females, and a high health assessment disability index among RA patients. CONCLUSIONS: RA patients experience limitations that affect their productivity at work and their QoL. Paying more attention to early management to prevent the upcoming unfavorable health and economic consequences for RA patients is significantly important.

Beyond the hand and upper extremity: The role of hand therapists in care of people with rheumatic diseases

STUDY DESIGN

Invited Clinical Commentary BACKGROUND: Arthritis is one of the most frequently reported causes of disability in the United States and the prevalence is expected to increase in the coming decades. While many rheumatic diseases involve hand impairments, most are systemic and involve more than the musculoskeletal system. Functional and work disability are high and people would benefit from the services of occupational and physical therapists.

PURPOSE OF STUDY

This paper reviews concepts of self-management, and symptoms that contribute to limitations and restrictions to participation in daily life in people with rheumatic diseases and suggests roles for hand therapists beyond the immediate hand impairments.

METHODS

The impact of selected rheumatic diseases on functional and work disability are reviewed along with strategies for symptom management and self-management. Upper extremity impairments of selected rheumatic diseases are also discussed.

RESULTS

The role for hand therapists in evaluating and addressing the complex needs of persons with rheumatic diseases, including less common diseases, is discussed. Outcome measures for fatigue, muscle involvement, ergonomics and computer use, and work disability are introduced. Finally, strategies for self-management and prevention of work and functional disability, along with symptom management for fatigue and pain are presented.

CONCLUSION

Hand therapists can play a vital role in chronic rheumatic disease management to improve self-management and increase participation in meaningful activities. Patients, primary care and rheumatology providers need to be educated about the scope of services occupational and physical therapists provide beyond the hand impairments.

Patient-reported outcomes of upadacitinib versus abatacept in patients with rheumatoid arthritis and an inadequate response to biologic disease-modifying antirheumatic drugs: 12- and 24-week results of a phase 3 trial

BACKGROUND

In previous clinical trials, patients with active rheumatoid arthritis (RA) treated with upadacitinib (UPA) have improved patient-reported outcomes (PROs). This post hoc analysis of SELECT-CHOICE, a phase 3 clinical trial, evaluated the impact of UPA vs abatacept (ABA) with background conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on PROs in patients with RA with inadequate response or intolerance to biologic disease-modifying antirheumatic drugs (bDMARD-IR).

METHODS

Patients in SELECT-CHOICE received UPA (oral 15 mg/day) or ABA (intravenous). PROs evaluated included Patient Global Assessment of Disease Activity (PtGA) by visual analog scale (VAS), patient's assessment of pain by VAS, Health Assessment Questionnaire Disability Index (HAQ-DI), morning stiffness duration and severity, 36-Item Short Form Health Survey (SF-36), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Work Productivity and Activity Impairment (WPAI), and EQ-5D 5-Level (EQ-5D-5L) index score. Least squares mean (LSM) changes from baseline to weeks 12 and 24 were based on an analysis of covariance model. Proportions of patients reporting improvements ≥ minimal clinically important differences (MCID) were compared using chi-square tests.

RESULTS

Data from 612 patients were analyzed (UPA, n=303; ABA, n=309). Mean age was 56 years and mean disease duration was 12 years. One-third received ≥2 prior bDMARDs and 72% received concomitant methotrexate at baseline. At week 12, UPA- vs ABA-treated patients had significantly greater improvements in PtGA, pain, HAQ-DI, morning stiffness severity, EQ-5D-5L, 2/4 WPAI domains, and 3/8 SF-36 domains and Physical Component Summary (PCS) scores (P<0.05); significant differences persisted at week 24 for HAQ-DI, morning stiffness severity, SF-36 PCS and bodily pain domain, and WPAI activity impairment domain. At week 12, significantly more UPA- vs ABA-treated patients reported improvements ≥MCID in HAQ-DI (74% vs 64%) and SF-36 PCS (79% vs 66%) and 4/8 domain scores (P<0.05).

CONCLUSIONS

At week 12, UPA vs ABA treatment elicited greater improvements in key domains of physical functioning, pain, and general health and earlier improvements in HAQ-DI. Overall, more UPA- vs ABA-treated patients achieved ≥MCID in most PROs at all timepoints; however, not all differences were statistically significant. These data, however, highlight the faster response to UPA treatment.

Systemic autoimmune diseases and work outcomes in Brazil: a scoping review

OBJECTIVE

To review articles that assessed work-related outcomes such as workability, work productivity, presenteeism, absenteeism, sick leave, return to work, and employment status of Brazilian patients with rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, Sjögren's syndrome, and systemic autoimmune myopathies.

METHODS

This study was conducted in Medline databases (PubMed), SciELO, and Lilacs through a combination of descriptors of interest. Studies published until December 2020 were considered in the search strategy.

RESULTS

Eight out of 90 articles met the eligibility criteria and were included in this review. The studies are highly heterogeneous. Most of them are cross-sectional, and all of them address rheumatoid arthritis or systemic lupus erythematosus. A common denominator among these studies is the high proportion of patients outside the labor market.

CONCLUSIONS

In general, the studies show unfavorable labor outcomes and impaired participation in the Brazilian workforce among the samples of patients assessed. There is a need to better understand several topics about Brazilian patients with systemic autoimmune diseases and their work context, as well as to conduct studies focusing on rarer diseases and on the themes of return and reintegration to work.

Work productivity in rheumatoid arthritis patients from two Latin American countries treated with tofacitinib or biological DMARDs

OBJECTIVE

To evaluate work productivity of adult Latin American patients with rheumatoid arthritis (RA) treated with tofacitinib and biological disease-modifying anti-rheumatic drugs (bDMARDs) measured by the Work Productivity and Activity Impairment (WPAI) in RA questionnaire at 0- and 6-month follow-up.

METHODS

This non-interventional study was performed in Colombia and Peru. Evaluated the effects of tofacitinib and bDMARDs in patients with RA after failure of conventional DMARDs. The WPAI-RA questionnaire was administered at baseline and at the 6-month (±1 month) follow-up. The results are expressed as least squares means (LSMs), and standard errors (SEs).

RESULTS

One hundred patients treated with tofacitinib and 70 patients treated with bDMARDs were recruited. Twenty-eight percent of patients from the tofacitinib group and 40.0% from the bDMARDs group were working for pay at baseline. At month 6, the changes in absenteeism, presenteeism, and work impairment due to health were -18.3% (SE 7.7), -34.8% (SE 5.9), and -11.0% (SE 16.5), respectively, in the tofacitinib group and -19.4% (SE 8.0), -34.8% (SE 6.2), and -15.9% (SE 15.0), for the bDMARD group.

CONCLUSION

For patients who reported working, there were improvements in presenteeism, absenteeism, and work impairment due to health in both groups.

Achievement of more stringent disease control is associated with reduced burden on workplace and household productivity: results from long-term certolizumab pegol treatment in patients with psoriatic arthritis

Background:

Psoriatic arthritis (PsA) impacts the physical health and functional ability of patients, leading to reduced productivity. High unemployment rates and absence due to sickness have been reported in patients with PsA.

Objectives:

This post hoc study investigated certolizumab pegol treatment impact on workplace and household productivity in patients with PsA, and assessed whether achievement of more stringent disease control was associated with greater improvements in productivity.

Design:

RAPID-PsA was a 216-week phase III trial.

Methods:

This post hoc study used a generalised estimating equations (GEE) model to examine the disease activity association, measured using American College of Rheumatology (ACR) and Disease Activity in PSoriatic Arthritis (DAPSA), and workplace and household productivity, assessed using an arthritis-specific Work Productivity Survey (WPS). The GEE model estimated the mean cumulative number of days patients meeting different disease control criteria were affected by absenteeism or presenteeism in the workplace and household.

Results:

In all, 273 patients were randomised to certolizumab pegol and 183 (67.0%) completed Week 216. At baseline, 60.8% of patients were employed outside the home. Improved disease control, measured using ACR and DAPSA criteria, was associated with fewer cumulative days affected by workplace absenteeism through Week 216: ACR70: 4.1 days, ACR50 to <70: 7.7, ACR20 to <50: 20.9, <ACR20: 35.7; DAPSA remission (REM): 3.3, low disease activity (LDA): 9.8, moderate disease activity (MoDA): 22.4, high disease activity (HDA): 54.0. Improved disease control was also associated with fewer days affected by workplace presenteeism: ACR70: 5.6, ACR50 to <70: 19.3, ACR20 to <50: 71.2, < ACR20: 141.2; DAPSA REM: 5.7, LDA: 25.8, MoDA: 77.2, HDA: 223.6. Similar associations between greater disease control and improved productivity were observed for household absenteeism and presenteeism.

Conclusion:

This post hoc study demonstrates the cumulative workplace and household work productivity benefits for patients with PsA when achieving more stringent thresholds of disease control with certolizumab pegol treatment.

Development of employment indicators to advance the quality of spinal cord injury rehabilitation care: SCI-High Project

CONTEXT

Employment and Return to Work (RTW) rates following spinal cord injury/disease (SCI/D) are low due to individual and impairments characteristics, secondary health conditions, social and environmental barriers, prior work experience, workplace supports and resources, and physical or psychosocial work demands. To improve RTW, the SCI-High Project team developed a set of Employment structure, process, and outcome indicators for adults with SCI/D in the first 18 months after rehabilitation admission.

METHODS

A pan-Canadian Working Group of diverse stakeholders: (1) defined the Employment construct; (2) conducted a systematic search of available outcomes measures; (3) constructed a Driver diagram summarizing factors associated with employment. Subsequent facilitated meetings allowed for the creation of structure and process indicators, and the selection of outcome indicators.

RESULTS

The structure indicator is the proportion of SCI/D rehabilitation programs with an employment resource center. The process indicator is the proportion of SCI/D rehabilitation inpatients who receive an employment assessment during inpatient rehabilitation. The intermediary and final outcome measures are the Readiness for Return-to-Work Scale (RRTW) and Work Productivity and Activity Impairment (WPAI). Scale A of the RRTW for those who are unemployed and Scale B of RRTW and WPAI will be used for those who are employed.

CONCLUSION

This framework of Employment indicators intends to support the RTW needs of persons with SCI/D by ensuring that rehabilitation professionals provide opportunities to explore RTW within the first 18 months after rehab admission. Increased employment rates have the potential to enhance the wellbeing, health, and longevity of individuals with SCI/D.

Patient and caregiver outcomes with levodopa-carbidopa intestinal gel in advanced Parkinson’s disease

Levodopa-carbidopa intestinal gel (LCIG) has shown to be efficacious in motor and non-motor symptoms (NMS). Nevertheless, studies with patient Quality of Life (QoL) as a primary endpoint are scarce. To assess the effect of LCIG on Advanced Parkinson’s Disease (APD) patients QoL. Secondarily, the impact on motor symptoms and NMS, emotional well-being, treatment satisfaction, and caregiver QoL, stress, disease burden, anxiety, depression, and work impairment were also investigated. In this prospective, 6-month multicenter postmarketing observational study, LCIG was administered to 59 patients with APD. Endpoints were assessed using validated scales and questionnaires. LCIG significantly improved patient QoL (PDQ-39 mean change ± standard deviation from baseline, −12.8 ± 14.6; P < 0.0001), motor symptoms (UPDRS-III in “On,” −6.5 ± 11.8; P = 0.0002), NMS (NMSS, −35.7 ± 31.1; P < 0.0001), mood (Norris/Bond-Lader VAS, −6.6 ± 21.1; P = 0.0297), fatigue (PFS-16, −0.6 ± 1.0; P = 0.0003), depression (BDI-II, −5.1 ± 9.4; P = 0.0002), anxiety (BAI, −6.2 ± 9.6; P < 0.0001), and patient treatment satisfaction (SATMED-Q, 16.1 ± 16.8; P < 0.0001). There were significant correlations between the change from baseline to 6 months between PDQ-39 and UPDRS-IV, NMSS, BAI, BDI-II, AS, and PFS-16 scores, and Norris/Bond-Lader alertness/sedation factor. Caregiver anxiety also improved (Goldberg anxiety scale, −1.1 ± 1.0; P = 0.0234), but the clinical relevance of this finding is questionable. The serious adverse events reported were similar to those previously described for LCIG. In patients with APD, LCIG improves QoL, motor symptoms and NMS, emotional well-being, and satisfaction with the treatment. Improvement in patient QoL is associated with improvements in motor complications, NMS, anxiety, depression, apathy and fatigue. Improvements in patients’ QoL does not correspond with improvements in caregivers’ QoL or burden.

Valuation of Lost Productivity in Caregivers: A Validation Study

Objective

This study aimed to: (a) adapt the previously validated Valuation of Lost Productivity (VOLP) questionnaire for people with health problems, to a caregiver version to measure productivity losses associated with caregiving responsibilities, and (b) evaluate measurement feasibility and validity of an online version of the caregiver VOLP questionnaire.

Methods

A mixed methods design was utilized. Qualitative methods, such as reviewing existing questionnaires that measured caregiver work productivity losses and performing one-on-one interviews with caregivers, were used for VOLP adaptation and online conversion. Quantitative methods were used to evaluate feasibility and validity of the online VOLP. The Work Productivity and Activity Impairment (WPAI) questionnaire for caregivers was included to compare its absenteeism and presenteeism outcomes and their correlations with VOLP outcomes.

Results

When adapting the VOLP for caregivers, our qualitative analysis showed the importance of adding three major components: caregiving time, work productivity loss related to volunteer activities and caregivers’ lost job opportunities. A total of 383 caregivers who completed online survey were included in our final quantitative analysis. We found small Spearman rank correlations between VOLP and WPAI, observing a larger correlation between their absenteeism [r = 0.49 (95% confidence interval: 0.37–0.60)] than their presenteeism [r = 0.36 (0.24–0.47)]. Correlations between VOLP outcomes and total caregiving hours were larger for absenteeism [r = 0.38 (0.27–0.47)] than presenteeism [r = 0.22 (0.10–0.34)]. Correlations between WPAI outcomes and total caregiving hours were smaller for absenteeism [r = 0.27 (0.15–0.38)] than presenteeism [r = 0.35 (0.23–0.46)].

Conclusion

The study provides evidence of the feasibility and preliminary validity evidence of the adapted VOLP caregiver questionnaire in measuring productivity losses due to caregiving responsibilities, when compared with the results for WPAI and the results from the previous patient-VOLP validation study.

Psychometric properties of the Work Limitations Questionnaire applied to nursing workers

OBJECTIVE

to evaluate the psychometric properties of the Work Limitations Questionnaire and to measure presenteeism in a sample of nursing workers.

METHOD

a cross-sectional study, with non-probabilistic sampling. Data was collected between July 2018 and February 2019 in two high-complexity hospitals, and the sample was composed of 304 participants. The validity analysis of the Work Limitations Questionnaire was performed by means of Confirmatory Factor Analysis.

RESULTS

most of the participants were women (88.5%), with a mean age of 40.9 years old. The validities of the factorial, convergent and discriminant construct and the reliability of the complete version and of the 16-item version of the instrument were adequate after adjusting the models to the sample. A statistically significant and negative correlation (p<0.001) was verified between the workload, working time and the Time Management and Physical Demands dimensions; as well as a statistically significant (p<0.001) correlation between working time and the Mental-Interpersonal Demands and Production Demands dimensions. Gender and professional category did not influence presenteeism. The rate of loss of productivity at work was 19.51%.

CONCLUSION

the Work Limitations Questionnaire showed adequate validity and reliability and can be considered a valid and reliable instrument for assessing presenteeism in the nursing team.

Work disability and rheumatoid arthritis: Predictive factors

BACKGROUND

Rheumatoid arthritis is often associated with work disability, a term used to describe the inability to be or to remain employed. Work disability is a common implication of rheumatoid arthritis.

OBJECTIVE

This review aims to identify and analyze the predictive factors of work disability among patients with rheumatoid arthritis, as well as to group these factors into broader categories, based on the most current studies in this field.

METHODS

An electronic search was conducted using Google Scholar, MEDLINE and PsycINFO databases. Eighty-six international journal articles were finally selected.

RESULTS

The results suggest that occupational, personal, medical and societal factors are the main predictive categories of work disability for people with rheumatoid arthritis.

CONCLUSIONS

Medical progress has had a positive effect on the development and the rates of work disability among patients with RA. Work disability is, however, not only defined by medical factors. Occupational, personal and societal factors interact with each other and affect the development of work disability in RA. The results of this review emphasize the need for medical and vocational therapy interventions, social support and state policies that target the work status of patients with RA. Future holistic research approaches to the field are required for a complete picture and concrete solutions with the aim of keeping patients with RA employed.

Methodological aspects of design, analysis and reporting of studies with work participation as an outcome domain in patients with inflammatory arthritis: results of two systematic literature reviews informing EULAR points to consider

Objective

To summarise the methodological aspects in studies with work participation (WP) as outcome domain in inflammatory arthritis (IA) and other chronic diseases.

Methods

Two systematic literature reviews (SLRs) were conducted in key electronic databases (2014–2019): search 1 focused on longitudinal prospective studies in IA and search 2 on SLRs in other chronic diseases. Two reviewers independently identified eligible studies and extracted data covering pre-defined methodological areas.

Results

In total, 58 studies in IA (22 randomised controlled trials, 36 longitudinal observational studies) and 24 SLRs in other chronic diseases were included. WP was the primary outcome in 26/58 (45%) studies. The methodological aspects least accounted for in IA studies were as follows (proportions of studies positively adhering to the topic are shown): aligning the studied population (16/58 (28%)) and sample size calculation (8/58 (14%)) with the work-related study objective; attribution of WP to overall health (28/58 (48%)); accounting for skewness of presenteeism/sick leave (10/52 (19%)); accounting for work-related contextual factors (25/58 (43%)); reporting attrition and its reasons (1/58 (2%)); reporting both aggregated results and proportions of individuals reaching predefined meaningful change or state (11/58 (16%)). SLRs in other chronic diseases confirmed heterogeneity and methodological flaws identified in IA studies without identifying new issues.

Conclusion

High methodological heterogeneity was observed in studies with WP as outcome domain. Consensus around various methodological aspects specific to WP studies is needed to improve quality of future studies. This review informs the EULAR Points to Consider for conducting and reporting studies with WP as an outcome in IA.

The impact of antineutrophil cytoplasmic antibody-associated vasculitis on employment and work disability in an Australian population

AIM

Although antineutrophil cytoplasmic antibody-associated vasculitis (AAV) most commonly affects older individuals, many patients develop the disease during their most productive working years. The aim of this study was to examine the effects of AAV on employment and work disability in a cohort of Australian patients of working age.

METHODS

Patients attending a vasculitis clinic located in Melbourne, Australia, completed an employment questionnaire in addition to the Work Productivity and Activity Impairment Questionnaire: Specific Health Problem.

RESULTS

The average age of the 47 respondents was 47.8 ± 11.9 years (range 22-63 years), with a median disease duration of 60 months (range 10.2-318.5 months). There were 68.1% who were currently employed, but 20.6% of respondents employed at the time of diagnosis were no longer working and 10.6% had experienced a significant reduction in work hours since their diagnosis. There were 12.7% who were dependent on the disability support pension. The rate of work disability was 23.4%. Many participants considered themselves work impaired (41.9%), with 10.1% having missed work in the previous week. Furthermore, 44.7% of respondents reported that their financial stability had been negatively impacted by their vasculitis diagnosis. Fatigue was commonly reported. Work disabled patients were significantly more likely to be obese and less likely to have completed a tertiary education. Work disabled patients tended to be older, myeloperoxidase-antineutrophil cytoplasmic antibody positive, and have renal involvement and lung involvement.

CONCLUSION

A proportion of people living with AAV in Australia experience a decline in employment and an increase in work disability when living with this condition.

Health-related quality of life and work impairment in idiopathic inflammatory myopathies in South Australia

AIM

The idiopathic inflammatory myopathies (IIM) are rare autoimmune diseases that are usually chronic and often present with skeletal muscle inflammation and weakness. We sought to examine the impact of IIM in a cohort of 50 South Australian patients on health-related quality of life (HRQOL) and work productivity (WP). We uniquely categorized patients across gender, IIM subtypes, employment status, and also whether there was extramuscular involvement from IIM.

METHODS

Multiple modalities were used, as recommended by the International Myositis Assessment and Clinical Studies Group (IMACS), to assess the impact of IIM, including manual muscle strength testing (MMT-8), the Physician and Patient Global Activity Assessments (PHGAA, PTGAA), Myositis Disease Activity Assessment Tool (MDAAT), and serum creatinine kinase (CK) levels. The impacts of IIM on HRQOL and WP were analyzed using the Medical Outcomes Study 36-items Short Form (SF-36) and Work Productivity and Activity Impairment (WPAI) questionnaires, respectively.

RESULTS

We found significantly lower HRQOL outcome scores in most of the SF-36 domains when compared to the most recent population norms (P ≤ .01). Physical health was predominantly affected with relative preservation of emotional health. There were also significant associations between MMT-8, PHGAA and PTGAA scores and HRQOL and WP.

CONCLUSIONS

Our findings highlight the significant impact of IIM on HRQOL and WP in a well-characterized cohort of patients with IIM within Australia, and therefore the importance of a holistic approach to the management of these patients.

Employment outcomes in systemic sclerosis

Work disability is highly prevalent in the systemic sclerosis (SSc) population; yet, it is an area of research that continues to be underrecognized and underexplored. In this chapter, we review the burden of this work disability by exploring the reported prevalence of work loss, the risk factors associated with reduced work participation, the impact on work productivity outcomes, and the economic consequences of work disability in individuals with SSc. Finally, we discuss the potential challenges in the workplace and strategies that may foster employment retention in this population. We subsequently present a conceptual framework for work disability in the context of SSc, which incorporates our understanding of the various work disability concepts and the potential facilitators that may accelerate a worker toward complete work loss.

Impaired health-related quality of life, psychological distress, and productivity loss in younger people with persistent shoulder pain: a cross-sectional analysis

PURPOSE

To investigate wellbeing and work impacts in younger people with persistent shoulder pain.

MATERIALS AND METHODS

People aged 20-55 years with shoulder pain of >6 weeks' duration (excluding those with recent fracture or dislocation) were recruited from orthopaedic clinics at three major public hospitals. Health-related quality of life (HRQoL) and psychological distress were evaluated using the Assessment of Quality of Life (AQoL) and K10 instruments and compared to population norms. Shoulder-related absenteeism and presenteeism were quantified using the Work Productivity and Activity Impairment (WPAI) Questionnaire.

RESULTS

Of the 81 participants (54% male), 69% had shoulder pain for over 12 months. Substantial HRQoL impairment was evident (mean reduction from population norms 0.33 AQoL units, 95% CI -0.38 to -0.27; minimal important difference 0.06 AQoL units). High or very high psychological distress was three times more prevalent among participants than the general population (relative risk 3.67, 95% CI 2.94 to 4.59). One-quarter of participants had ceased paid employment due to shoulder pain and 77% reported shoulder-related impairment at work.

CONCLUSIONS

The broader impacts of painful shoulder conditions on younger people extend well beyond pain and upper limb functional limitations. In particular, the work-related impacts should form a routine part of patient assessment and rehabilitation.Implications for rehabilitationPersistent shoulder pain in younger people (aged 20-55 years) is associated with substantially reduced health-related quality of life and greater psychological distress, compared to population norms, as well as work participation and productivity impacts.As rotator cuff conditions, shoulder capsule pathology, and glenohumeral instability are relatively common, our data suggest that persistent shoulder pain is likely to have a high community impact among people of working age.Information resources that people with painful shoulder conditions can share with their families, employers, and colleagues may assist others to better understand the broader impacts of these conditions.Work-related challenges associated with shoulder pain should be considered within routine clinical care, and may require referral to an occupational health clinician or vocational rehabilitation service.

Evaluation of the Structural Validity of the Work Instability Scale Using the Rasch Model

Objective

To use Rasch analysis to examine the measurement properties of the 23-item version of the Work Instability Scale (WIS-23) in a sample of worker compensation claimants with upper extremity disorders.

Design

Secondary data analysis on the data retrieved from a cross-sectional study.

Setting

Tertiary care hospital.

Participants

Patients (N=392) attending a specialty clinic for workers with upper limb injuries at a tertiary hospital were prospectively enrolled.

Interventions

Not applicable.

Main Outcome Measures

WIS-23.

Results

The study sample contained 392 participants between the ages of 19 and 73 years (mean, 47.0±10.5y). There were 148 (37.8%) women, 182 (46.4%) men, and 62 (15.8%) participants for whom sex identification was unavailable. The initial WIS data analysis showed significant misfit from the Rasch model (item-trait interaction: χ²=293.52; P<.0001). Item removal and splitting were performed to improve the model fit, resulting in a 20-item scale that met all assumptions (χ²=160.42; P=.008), including unidimensionality, local independence of items, and the absence of differential item function based on age, sex of respondents, employment type, and affected upper extremity area across all tested factors.

Conclusion

With the application of Rasch analysis, we refined the WIS-23 to produce a 20-item WIS for work-related upper extremity disorders (WIS-WREUD). The 20-item WIS-WREUD demonstrated excellent item and person fit, unidimensionality, acceptable person separation index, and local independency. The WIS-20 may provide better measurement properties, although longitudinal psychometric evaluations are needed.

The Health-Related Quality of Life, Work Productivity, Healthcare Resource Utilization, and Economic Burden Associated with Levels of Suicidal Ideation Among Patients Self-Reporting Moderately Severe or Severe Major Depressive Disorder in a National Survey

BACKGROUND

Suicidal ideation (SI) is a cardinal aspect of major depressive disorder (MDD); however, patient-reported outcomes data from large-scale surveys are limited concerning SI in the context of MDD. This study aims to understand the association between varying levels of SI and health-related quality of life (HRQoL), work productivity, healthcare resource utilization (HRU), and associated costs in patients with moderately severe/severe MDD.

METHODS

This was a retrospective, cross-sectional analysis of 2013 national survey data. Patients who self-reported moderately severe or severe MDD and completed the Short Form Survey Version 2 (SF-36v2), Work Productivity Loss and Activity Impairment questionnaire (WPAI), and questions related to HRU were analyzed. Direct and indirect costs were calculated. Patients were categorized and analyzed by the level of SI (no SI, low, moderate, and high) based on their response to Item 9 of the Patient Health Questionnaire-9.

RESULTS

Among 75,000 respondents, 15.3% self-reported receiving a physician diagnosis of moderately severe or severe MDD and 2.8% of the total sample endorsed some level of SI. Patients with high SI showed a higher burden than patients with no SI, reporting lower mean SF-36v2 mental component summary scores (p<0.001), higher work productivity loss (p=0.039), and higher numbers of per patient per month hospitalizations (p=0.002) and emergency room visits (p=0.011). High SI was associated with greater per patient per month direct costs ($1220 vs $796; p=0.002) and indirect costs ($1449 vs $1058; p=0.001) compared with no SI. When patients with low or moderate SI were compared with patients with no SI, the results were mixed.

CONCLUSION

Higher levels of SI were associated with lower HRQoL, greater HRU, and more work impairment resulting in higher direct and indirect costs compared with patients with MDD but no SI. These results highlight the need to implement effective treatment models and interventions in the employed population.

An Evaluation of the Structural Validity of the Work Limitation Questionnaire Using the Rasch Model

OBJECTIVE

To investigate the targeting, scaling, and structural validity of the Work Limitation Questionnaire (WLQ) using Rasch analysis.

DESIGN

Secondary data analysis.

SETTING

Tertiary care hospital.

PARTICIPANTS

The data were sourced from an upper limb specialty clinic of injured workers using the convenience sampling method and from a national randomized controlled trial investigating 2 surgical options for rotator cuff repair by formal, randomized selection (N=315).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Work Limitation Questionnaire 25-item version (WLQ-25). The WLQ contains 25 items measuring a client's ability to perform specific job demands on a 5-point ordinal response scale ranging from 0 (difficulty none of the time) to 4 (difficulty all the time). The average of all 25 items is used as the total score, ranging from 0 to 4, where higher index scores indicate greater difficulty performing daily work. Subscales were used to assess time management, physical demands (PD), mental-interpersonal demands, and output demands.

RESULTS

The Rasch analyses performed on the dataset included the test of fit of residuals, ordering of item thresholds, Person separation index, differential item functioning (DIF), dependency, and unidimensionality. The partial credit model was selected for the current Rasch analysis because the likelihood ratio test was significant at both the overall questionnaire and the subscale level (P<.001). The WLQ-25 did not fit with the Rasch model (χ²=1715.58; df=125; P<.001) and most of the thresholds were disordered. A series of steps were undertaken to improve the fit statistic, including item reduction (6 items) and response merging (9 items). DIF was absent in the revised scale based on sex, age, full- or part-time employment, and type of employment. Only 3 revised subscales, namely the PD, mental demands, and interpersonal demands subscales, demonstrated acceptable fit to the Rasch model.

CONCLUSIONS

The WLQ-25 demonstrated substantial misfit from the Rasch model, which could not be fully mediated. The revised PD, mental demands, and interpersonal demands subscales could be used to assess these constructs.

Results from a prospective longitudinal survey of employment and work outcomes in newly diagnosed cancer patients during and after curative-intent chemotherapy: A Wisconsin Oncology Network study

BACKGROUND

Postcancer work limitations may affect a substantial proportion of patients and contribute to the "financial toxicity" of cancer treatment. The degree and nature of work limitations and employment outcomes are poorly understood for cancer patients, particularly in the immediate period of transition after active treatment. We prospectively examined employment, work ability, and work limitations during and after treatment.

METHODS

A total of 120 patients receiving curative therapy who were employed prior to their cancer diagnosis and who intended to work during or after end of treatment (EOT) completed surveys at baseline (pretreatment), EOT, and 3, 6, and 12 months after EOT. Surveys included measures of employment, work ability, and work limitations. Descriptive statistics (frequencies, percentages, means with standard deviations) were calculated.

RESULTS

A total of 111 participants completed the baseline survey. On average, participants were 48 years of age and were mostly white (95%) and female (82%) with a diagnosis of breast cancer (69%). Full-time employment decreased during therapy (from 88% to 50%) and returned to near prediagnosis levels by 12-month follow-up (78%). Work-related productivity loss due to health was high during treatment.

CONCLUSIONS

This study is the first to report the effects of curative intent cancer therapy on employment, work ability, and work limitations both during and after treatment. Perceived work ability was generally high overall 12 months after EOT, although a minority reported persistent difficulty. A prospective analysis of factors (eg, job type, education, symptoms) most associated with work limitations is underway to assist in identifying at-risk patients.

Shoulder pain cost-of-illness in patients referred for public orthopaedic care in Australia

Objective The aim of this study was to calculate the societal economic burden of shoulder pain in patients on the orthopaedic waiting list at an Australian public hospital and calculate the cost (from the government's perspective) of care delivered by the hospital for those patients. Methods A cost-of-illness analysis was undertaken in a cohort of 277 orthopaedic patients on the Gold Coast in Australia. Outcomes included a health care costs and impacts questionnaire, work absenteeism, presenteeism questionnaires (Work Limitations Questionnaire (WLQ) and Work Productivity and Activity Impairment Questionnaire (WPAI)) and hospital care provision over a 2-year period. Results The mean societal cost of healthcare and domestic support was AU$20.72 per day (AU$7563 annually) per patient on the orthopaedic waiting list. When absenteeism and presenteeism were included, the cost per patient who was employed was AU$38.04 per day (AU$13885 annually) calculated with the WLQ and AU$61.31 per day (AU$22378 annually) calculated with the WPAI. The mean per-patient cost to government of public hospital care was AU$2622 in Year 1 and AU$3835.78 (s.d. 4961.28) over 2 years. The surgical conversion rate was 22%, and 51% of hospital care cost was attributable to outpatient services. Conclusions Public orthopaedic shoulder waiting lists create a large economic burden for society; few referrals require surgery and just over half the hospital care costs are for out-patient services. New models of care that better manage shoulder pain and identify surgical candidates before orthopaedic referral could reduce this burden. What is known about the topic? Little is known about the cost of shoulder pain in Australia, or the cost of patients referred for public orthopaedic care. What does this paper add? This article quantifies the costs of shoulder pain and the value of lost production from shoulder pain. The time spent waiting for public hospital orthopaedic appointments and the costs associated with waiting demonstrate that the time spent on a waiting list is a key driver of the economic burden. What are the implications for practitioners? Greater resourcing to reduce public orthopaedic shoulder waiting lists may be helpful, but system change is also required. Earlier and more accurate identification of surgical cases could reduce inefficient referrals and improve hospital productivity. Collaboration between clinicians and policy makers is needed to design more economically efficient shoulder care.

Impact of nutrition interventions and dietary nutrient density on productivity in the workplace

The global spread of diet-related noncommunicable diseases represents a threat to public health and national economies alike. The elimination of poverty and the eradication of hunger, two key United Nations Sustainable Development Goals, cannot be accomplished without a well-nourished labor force. Easy access to low-cost diets that are energy dense but nutrient poor has resulted in hidden hunger, in which micronutrient deficiencies coexist with obesity or overweight. Workplace interventions in low- and middle-income countries have addressed nutrient adequacy and micronutrient deficiencies, often using fortified foods. Workplace interventions in high-income countries have largely focused on weight loss, smoking cessation, stress reduction, and physical activity. Even though improvement of productivity may have been the ultimate goal, relatively few interventions in high-income countries have explored the likely impact of improved dietary nutrient density on workplace performance. Given that optimal nutrition benefits both physical and mental health, interventions to improve diet quality ought to have a measurable impact on the productivity of the labor force. The present review examines the evidence linking workplace dietary interventions with workplace productivity measures.

Occupational advice to help people return to work following lower limb arthroplasty: the OPAL intervention mapping study

BACKGROUND

Hip and knee replacements are regularly carried out for patients who work. There is little evidence about these patients' needs and the factors influencing their return to work. There is a paucity of guidance to help patients return to work after surgery and a need for structured occupational advice to enable them to return to work safely and effectively.

OBJECTIVES

To develop an occupational advice intervention to support early recovery to usual activities including work that is tailored to the requirements of patients undergoing hip or knee replacements. To test the acceptability, practicality and feasibility of this intervention within current care frameworks.

DESIGN

An intervention mapping approach was used to develop the intervention. The research methods employed were rapid evidence synthesis, qualitative interviews with patients and stakeholders, a prospective cohort study, a survey of clinical practice and a modified Delphi consensus process. The developed intervention was implemented and assessed during the final feasibility stage of the intervention mapping process.

SETTING

Orthopaedic departments in NHS secondary care.

PARTICIPANTS

Patients who were in work and intending to return to work following primary elective hip or knee replacement surgery, health-care professionals and employers.

INTERVENTIONS

Occupational advice intervention.

MAIN OUTCOME MEASURES

Development of an occupational advice intervention, fidelity of the developed intervention when delivered in a clinical setting, patient and clinician perspectives of the intervention and preliminary assessments of intervention effectiveness and cost.

RESULTS

A cohort study (154 patients), 110 stakeholder interviews, a survey of practice (152 respondents) and evidence synthesis provided the necessary information to develop the intervention. The intervention included information resources, a personalised return-to-work plan and co-ordination from the health-care team to support the delivery of 13 patient and 20 staff performance objectives. To support delivery, a range of tools (e.g. occupational checklists, patient workbooks and employer information), roles (e.g. return-to-work co-ordinator) and training resources were created. Feasibility was assessed for 21 of the 26 patients recruited from three NHS trusts. Adherence to the defined performance objectives was 75% for patient performance objectives and 74% for staff performance objectives. The intervention was generally well received, although the short time frame available for implementation and concurrent research evaluation led to some confusion among patients and those delivering the intervention regarding its purpose and the roles and responsibilities of key staff.

LIMITATIONS

Implementation and uptake of the intervention was not standardised and was limited by the study time frame. Evaluation of the intervention involved a small number of patients, which limited the ability to assess it.

CONCLUSIONS

The developed occupational advice intervention supports best practice. Evaluation demonstrated good rates of adherence against defined performance objectives. However, a number of operational and implementation issues require further attention.

FUTURE WORK

The intervention warrants a randomised controlled trial to assess its clinical effectiveness and cost-effectiveness to improve rates and timing of sustained return to work after surgery. This research should include the development of a robust implementation strategy to ensure that adoption is sustained.

Arthritis-related work outcomes experienced by younger to middle-aged adults: a systematic review

OBJECTIVE

The aim of this review was to systematically identify, appraise and synthesise evidence on work-related outcomes experienced by younger to middle-aged adults (aged 16-50 years) with arthritis.

METHODS

Eligible studies were identified in Medline, PsycINFO, Embase and CINAHL in January 2020. Quantitative and qualitative studies containing self-reported data on work-related outcomes on younger/middle-aged adults with arthritis were included. Quality assessment was undertaken using validated quality appraisal tools from the Joanna Briggs Institute.

RESULTS

Thirty-four studies were identified for inclusion. Work outcomes were organised around five themes: (1) arthritis-related work productivity outcomes, (2) arthritis-related work participation outcomes, (3) other arthritis-related workplace outcomes, (4) barriers to work participation associated with arthritis and (5) enablers to work participation associated with arthritis. Arthritis was associated with work limitations on the Workplace Activity Limitations Scale (average scores ranging from 5.9 (indicating moderate workplace difficulty) to 9.8 (considerable workplace difficulty)), and higher work disability prevalence rates (range: 6%-80%) relative to healthy populations. Arthritis was not associated with decreased absenteeism on the Work Productivity and Activity Impairment Questionnaire (mean (SD) 7.9% (14.0%)), indicating low levels of absenteeism, similar to healthy populations. As work outcomes were commonly binary, person-centred (qualitative) perspectives on barriers and enablers augmented the quantitative findings.

CONCLUSION

Arthritis is commonly associated with poorer work outcomes for younger/middle-aged adults relative to healthy populations. Additional research focusing solely on the workplace needs of younger/middle-aged population groups is required to inform tailored interventions and workplace support initiatives to maximise productive working years.

Development and validation of a questionnaire assessing household work limitations (HOWL-Q) in women with rheumatoid arthritis

INTRODUCTION

Rheumatoid arthritis (RA) has female preponderance and interferes with the ability to perform job roles. Household work has 2 dimensions, paid and unpaid. There is not a validated instrument that assesses the impact of RA on limitations to perform household work. We report the development and validation of a questionnaire that assesses such limitations, the HOWL-Q.

METHODS

The study was performed in 3 steps. Step-1 consisted on HOWL-Q conceptual model construction (literature review and semi-structured interviews to 20 RA outpatients and 20 controls, household workers, who integrated sample (S)-1). Step-2 consisted of instructions selection (by 25 outpatients integrating S-2), items generation and reduction (theory and key informant suggestions, modified natural semantic network technique, and pilot testing in 200 household workers outpatients conforming S-3), items scoring, and questionnaire feasibility (in S-3). Step-3 consisted of construct (exploratory factor analysis) and criterion validity (Spearman correlations), and HOWL-Q reliability (McDonald's Omega and test-retest), in 230 household work outpatients integrating S-4.

RESULTS

Patients conforming the 4 samples were representative of typical RA outpatients. The initial conceptual model included 8 dimensions and 76 tasks/activities. The final version included 41 items distributed in 5 dimensions, was found feasible and resulted in 62.46% of the variance explained: McDonald's Omega = 0.959, intraclass-correlation-coefficient = 0.921 (95% CI = 0.851-0.957). Moderate-to-high correlations were found between the HOLW-Q, the HAQ, the Quick-DASH and the Lawton-Brody index. HOWL-Q score ranged from 0 to 10, with increasing scores translate into increase limitations.

CONCLUSION

The HOWL-Q showed adequate psychometric properties to evaluate household work limitations in women with RA.

Biologic disease-modifying anti-rheumatic drugs and patient-reported outcomes in axial SpA: a systematic review and a call for action

This paper is to assess the efficacy of different biologic DMARDs (bDMARDs) on several patient-reported outcomes (PROs) in randomized controlled trials (RCT) in axial spondyloarthritis (axSpA). A systematic literature review (SLR) was performed. MEDLINE (May 1, 2018) was used with the filters "published in the last 10 years" and "humans." The PICO criteria used were Patients: adults with radiographic axSpA (r-axSpA) or non-radiographic axSpA (nr-axSpA); Intervention: any bDMARD; Compararator: placebo (PBO)/any different drug; Outcome: the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), the Ankylosing Spondylitis Quality of Life (ASQoL), the EuroQol-5D (EQ-5D), the Short Form 36 Health Survey physical component summary (SF36-PCS), the Short Form 36 Health Survey mental component summary (SF36-MCS), and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). After screening 84 initial references and manually selecting other 9, 24 publications, assessing TNF inhibitors (TNFi) or IL17A inhibitors (IL17Ai) were selected. Four RCTs quantified the minimal clinical important difference (MCID) between treatment arms. Most of the RCTs compared the mean difference of PROs between different timepoints. Overall, the treatment arm was superior to the comparator. PROs were often underreported or highly heterogeneously presented. MCID was seldom mentioned. There is a need to raise the standard of care on SpA by aiming at remission and PRO associated improvements. In order to achieve this goal, the target must be clearly defined, reported, and tested.

Managing work participation for people with rheumatic and musculoskeletal diseases

Improving work participation for individuals with rheumatic and musculoskeletal diseases (RMDs), has gained increasing interest over the last 10 years. New approaches are based upon increasing adoption of a biopsychosocial approach to improving work participation, incorporating evidence that health professionals within multidisciplinary teams have a key and critical role. In particular, interaction between health professionals and employers, and rehabilitation services that are linked to the workplace are key elements for improving work participation for people with RMDs. This review outlines recent research that underpins approaches for health professionals to develop their role in improving work participation for people with RMDs based on recent research; it outlines how to measure work-related outcomes in clinical practice, models of work participation, and approaches for health professionals to improve work participation outcomes. The potential for developing the role of health professionals in future years is also outlined.

Response to tocilizumab and work productivity in patients with rheumatoid arthritis: 2-year follow-up of FIRST ACT-SC study

OBJECTIVES

We evaluated long-term control of rheumatoid arthritis (RA) in Japanese paid workers (PWs) and house workers (HWs) treated with subcutaneous tocilizumab (TCZ-SC) and explored factors affecting response to TCZ-SC regarding work productivity.

METHODS

This study collected data from patients with RA in the TCZ-SC +/- conventional synthetic disease-modifying antirheumatic drugs group. Factors affecting the response to tocilizumab regarding work productivity were explored using logistic regression. Differences in quality-adjusted life years (QALYs) between with/without response were analysed by a linear regression.

RESULTS

Data were analysed for 357/360 patients. Patients with a ≥ 75% improvement in activity impairment (AI) were considered responders. EuroQol-5 Dimension (EQ-5D), six-item Kessler psychological distress scale score (K6), Health Assessment Questionnaire Disability Index (HAQ-DI), and the patient's disease global health by visual analogue scale were significant contributors to TCZ-SC response based on improvements in AI. Work Functioning Impairment Scale, presenteeism, EQ-5D, K6, and HAQ-DI significantly contributed to the improvement of overall work impairment in PWs. Shorter disease duration also was related to TCZ-SC response based on AI improvements. Responders had significantly larger mean QALYs than non-responders (difference = 0.2614; p < .001).

CONCLUSIONS

These real-world clinical data support long-term work productivity control with TCZ-SC for biologic-naïve HWs and PWs with RA.

Breast Reconstruction May Improve Work Ability and Productivity After Breast Cancer Surgery

OBJECTIVE

The aim of this study was to evaluate work ability and productivity in women who had undergone different types of surgical treatment for breast cancer, as well as breast reconstruction after mastectomy.

METHODS

This cross-sectional study assessed 152 women between 30 and 60 years of age, who worked outside the home in formal or informal jobs, or as self-employed. Thirty-eight of them had no history of breast cancer (control group), and 114 had undergone surgical treatment for breast cancer at least 1 year before their enrollment in the study, and were allocated as follows: mastectomy group (n = 38), breast-conserving surgery group (n = 38), or breast reconstruction breast reconstruction group (n = 38). The validated Brazilian versions of the Work Productivity and Activity Impairment-General Health questionnaire and Work Limitations Questionnaire were self-administered.

RESULTS

The groups were homogeneous regarding age, education level, and other sociodemographic characteristics. Patients in the mastectomy and breast-conserving surgery groups showed reduced work performance and productivity compared with women in the breast reconstruction and control groups (P = 0.0004 and P = 0.0006, respectively). In addition, women in the mastectomy group had more difficulty in performing activities of daily living compared with those in other groups (P = 0.0121).

CONCLUSIONS

Women who had undergone mastectomy or breast-conserving surgery had decreased work ability and productivity compared with women without a history of breast cancer and to those who had undergone breast reconstruction.

Burden of rheumatoid arthritis on patients' work productivity and quality of life

BACKGROUND

To determine the burden of Rheumatoid Arthritis (RA) on patients' work productivity and health related quality of life (HRQoL), and examine the influence of several exposure variables; to analyze the progression of RA over 1 year and its impact on work productivity and HRQoL.

METHODS

International multicenter prospective survey including patients in 18 centers in Argentina, Brazil, Colombia and Mexico with diagnosis of RA and aged between 21-55 years. The following standard questionnaires were completed at baseline and throughout a 1-year follow-up: WPAI:RA, WALS, WLQ-25, EQ-5D-3 L and SF-36. Clinical and demographic variables were also collected through interview.

RESULTS

The study enrolled 290 patients on baseline visit. Overall mean scores at baseline visit were: WPAI:RA (presenteeism) = 29.5% (SD = 28.8%); WPAI:RA (absenteeism) = 9.0% (SD = 23.2%); WPAI:RA (absenteeism and presenteeism) = 8.6% (SD = 22.6%); WALS = 9.0 (SD = 6.1); WLQ-25 = 7.0% (SD = 5.1%); SF-36 Physical Scale = 39.1 (SD = 10.3) and Mental Scale = 45.4 (SD = 11.3); EQ-5D-3 L VAS = 69.8 (SD = 20.4) and EQ-5D-3 L index = 0.67 (SD = 0.23). Higher educational levels were associated with better results in WLQ-25, while previous orthopedic surgeries reduced absenteeism results of WPAI:RA and work limitations in WLQ-25. Higher disease duration was associated with decreased HRQoL. Intensification of disease activity was associated with decreased work productivity and HRQoL, except in WLQ-25. In the longitudinal analysis, worsening in disease activity was associated with a decrease in both work productivity and HRQoL.

CONCLUSIONS

RA patients are dealing with workplace disabilities and limitations and loss in HRQoL, and multiple factors seems to be associated with this. Worsening of disease activity further decreased work productivity and HRQoL, stressing the importance of disease tight control.

Humanistic and Economic Impact of Moderate to Severe Plaque Psoriasis in Brazil

INTRODUCTION

Psoriasis is an immune-mediated, chronic, inflammatory disease, which has a substantial humanistic and economic burden. This study aimed to assess the impact of this disease on health-related quality of life (HRQoL), work productivity, and direct and indirect costs from a societal perspective among Brazilian patients.

METHODS

This is a cross-sectional, observational, multicenter study, enrolling patients with moderate to severe plaque psoriasis according to physician evaluation. Data collection was performed from December 2015 to November 2016 through face-to-face interviews using a structured questionnaire and five standardized patient-reported outcomes instruments. Direct costs were estimated by multiplying the amount of resources used (12-month recall period) by the corresponding unit cost. Indirect costs were grouped in two time horizons: annual costs (income reduction and absenteeism) and lifetime costs (demission and early retirement).

RESULTS

A total of 188 patients with moderate to severe plaque psoriasis were included, with mean age of 48.0 (SD 13.1). "Anxiety and depression" and "pain and discomfort" were the most impaired dimensions, according to the EuroQol Five-Dimension-Three-Level (EQ-5D-3L). The highest effect was found for "symptoms and feelings" [mean (SD) 2.4 (1.7)] Dermatology Life Quality Index (DLQI) subscale. Psoriatic arthritis (PsA) presence and biologic-naïve status were associated with worse HRQoL. Presenteeism was more frequent than absenteeism, according to the Work Productivity and Activity Impairment questionnaire-General Health (WPAI-GH) [17.4% vs. 6.3%], while physical demands and time management were the most affected Work Limitations Questionnaire (WLQ) subscales [means (SD) 23.5 (28.5) and 17.7 (24.9), respectively]. The estimated annual cost per patient was USD 4034. Direct medical costs accounted for 87.7% of this estimate, direct non-medical costs for 2.4%, and indirect costs for 9.9%.

CONCLUSIONS

Results evidenced that moderate to severe plaque psoriasis imposes substantial costs to society. Our data showed that this disease negatively affects both work productivity and HRQoL of Brazilian patients. Subgroups with PsA and biologic-naïve patients presented lower HRQoL, showing the impact of this comorbidity and the relevance of biologics in psoriasis treatment.

Delaying voiding, limiting fluids, urinary symptoms, and work productivity: A survey of female nurses and midwives

AIM

To examine the relationships between workplace bladder practices, urinary symptoms, and work productivity.

DESIGN

Cross-sectional observational survey.

METHODS

Surveys were distributed June-November 2016 to at least 600 female nurses and midwives at three urban hospitals in New South Wales, Australia. Nurses self-reported restricted workplace access to toilets, delaying voiding, limiting of fluid intakes and urinary symptoms at work. Logistic modelling was used to examine whether nurses' bladder practices impaired their time management, ability to concentrate or perform physical demands.

RESULTS

Of 353 useable surveys, one in five nurses (22.4%; N = 79) reported restricted access to toilets at work, most (77.1%; N = 272) delayed voiding and one in four (26.9%; N = 95) limited fluid intakes to delay voiding at work. Almost half the sample had urinary symptoms at work (46.7%; N = 165); delaying voiding increased the likelihood of impaired mental concentration and limiting fluid intakes increased the likelihood of impaired time management.

CONCLUSION

As workplace access to toilets and related bladder practices are modifiable, associated urinary symptoms and productivity loss may be preventable.

IMPACT

Nurses' often experience restricted accesses to amenities due to job demands and workplace environments. The impact of nurses' poor bladder practices in the workplace is not known. In this study most nurses delayed voiding and many purposefully limited fluid intakes at work. These behaviours impacted a nurse's ability to manage time and/or concentrate at work. Results have implications for nurses' personal health, the design of workplace environments, workforce management, occupational health policy, and patient care.

Long-term efficacy and cost-effectiveness of infliximab as first-line treatment in rheumatoid arthritis: systematic review and meta-analysis

Introduction: Early biological treatment of rheumatoid arthritis (RA) may reverse the autoimmune response in some patients resulting in favorable long-term outcomes. Although the cost-effectiveness of this strategy has been questioned, biosimilar entries warrant the revision of clinical and pharmaco-economic evidence. Areas covered: We conducted a systematic review of randomized controlled trials (RCTs) published up to 24 May 2018 in Pubmed, EMBASE and Cochrane CENTRAL, comparing infliximab with non-biological therapy in patients with RA naïve to methotrexate. We performed meta-analyses for efficacy outcomes at month 6 and years 1 and 2. Six RCTs were identified, involving 1832 patients. At month 6 ACR70 response and remission, and at year 1 ACR20/ACR70 responses and remission were improved significantly with first-line infliximab versus control. The differences were not significant at year 2. We reviewed cost-utility studies, up to 31 October 2018 in PubMed, Cochrane CENTRAL and the CRD HTA databases. Four studies indicated that first-line use of originator infliximab calculated at 2005-2008 prices was not cost-effective. Expert opinion: We demonstrated the efficacy benefits of first-line infliximab therapy up to 1 year in methotrexate-naïve RA. We highlighted the need for standardized reporting of outcomes and conducting cost-effectiveness analyses of first-line biosimilar therapy in RA.

Assessment in Work Productivity and the Relationship with Cognitive Symptoms (AtWoRC): primary analysis from a Canadian open-label study of vortioxetine in patients with major depressive disorder (MDD)

OBJECTIVE

The Assessment in Work Productivity and the Relationship with Cognitive Symptoms (AtWoRC) study aimed to assess the association between cognitive symptoms and work productivity in gainfully employed patients receiving vortioxetine for a major depressive episode (MDE).

METHODS

Patients diagnosed with major depressive disorder (MDD) and treated with vortioxetine independently of study enrollment were assessed over 52 weeks at visits that emulated a real-life setting. Patients were classified as those receiving vortioxetine as the first treatment for their current MDE (first treatment) or having shown inadequate response to a previous antidepressant (switch). The primary endpoint was the correlation between changes in patient-reported cognitive symptoms (20-item Perceived Deficits Questionnaire [PDQ-D-20]) and changes in work productivity loss (Work Limitations Questionnaire [WLQ]) at week 12. Additional assessments included changes in symptom and disease severity, cognitive performance, functioning, work loss, and safety.

RESULTS

In the week 12 primary analysis, 196 eligible patients at 26 Canadian sites were enrolled, received at least one treatment dose, and attended at least one postbaseline study visit. This analysis demonstrated a significant, strong correlation between PDQ-D-20 and WLQ productivity loss scores (r=0.634; p<0.001), and this correlation was significant in both first treatment and switch patients (p<0.001). A weaker correlation between Digit Symbol Substitution Test and WLQ scores was found (r=-0.244; p=0.003).

CONCLUSION

At 12 weeks, improvements in cognitive dysfunction were significantly associated with improvements in workplace productivity in patients with MDD, suggesting a role for vortioxetine in functional recovery in MDD.

Achieving comprehensive remission or low disease activity in rheumatoid patients and its impact on workability - Saudi Rheumatoid Arthritis Registry

Purpose

Ability to work is an important endpoint in rheumatoid arthritis (RA). It is not clear what outcome measures should be used to guide treatment in order to maximize workability. This study addressed the impact of RA on workability in a Saudi population and examined the correlation between objective measures of disease activity and reduced workability. This will allow better understanding of treatment targets that will translate into improved workability.

Patients and methods

Data were collected through a digital patient record keeper: The Rheumatoid Arthritis Saudi Database. Male and female patients, ≥18 years of age, that met the American College for Rheumatology criteria for diagnosis of RA, were recruited, regardless of treatment. Demographic and disease-specific data were collected. Disease Activity Score-28 (DAS-28) was used to define patients as low (DAS-28 ≤3.2) vs high (DAS-28 >3.2) disease activity. Health assessment questionnaire (HAQ) score, visual analog scale (VAS) score, and musculoskeletal ultrasound 7 joint score were documented also. The work productivity and activity impairment (WPAI) score was used to measure absenteeism, presenteeism, overall work impairment, and activity impairment. DAS-28 score was correlated with WPAI score and linear regression used to identify the demographic and measures of treatment response that predict improvement in WPAI score.

Results

Higher absenteeism and more activity impairment were seen for patients with persistent DAS-28 >3.2 (non-achievers). HAQ and VAS scores correlated with presenteeism, overall work impairment, and activity impairment.

Conclusion

Disease activity, as defined by DAS-28 score, correlates with absenteeism and work impairment in a Saudi population. However, on linear regression analysis, HAQ and VAS scores were the only measures predictive of work impairment. These scores should be used to monitor response to treatment regimens that aim to maximize work potential for Saudi individuals.

Treatment with golimumab or infliximab reduces health resource utilization and increases work productivity in patients with ankylosing spondylitis in the QUO-VADIS study, a large, prospective real-life cohort

AIM

We evaluated the effects of anti-tumor necrosis factor (TNF) agents on health economics in ankylosing spondylitis (AS) patients.

METHODS

QUality of Life as Outcomes and its VAriation with DIsease States (QUO-VADIS) was a prospective observational study following bio-naïve AS patients (modified New York criteria) newly treated with golimumab (GLM) or infliximab (IFX; originator) in a clinical practice setting over 6 months. We evaluated use of concomitant medications, hospitalizations (in-patient care or acute care) and visits in day care and out-patient settings for the assessment of healthcare resource utilization (HCRU). Work productivity and activity impairment (WPAI) was assessed by the number of work days missed and quantifying absenteeism, presenteeism, work impairment, and activity using the WPAI instrument adapted to spondyloarthritis (WPAI-SpA).

RESULTS

Nine hundred and sixty-three patients received ≥1 dose of medication (78%, n = 751 GLM; 22%, n = 221 IFX). Mean age was 42.7 years; 61.4% were male. At baseline, the percentage of patients who reported hospitalizations (in-patient care) was 13.6%, which decreased to 3.1% at 6 months, while out-patient care at baseline was reported by 39.4% of patients, which decreased to 19.0% at 6 months. The percentage of patients receiving acute emergency at baseline reduced from 1.6% to 0.3% at 6 months. The mean (SD) number of days of work missed due to AS, was reduced from 6.3 (31.1) days at baseline to 2.7 (12.3) days at 6 months.

CONCLUSION

In patients with AS newly treated with GLM or IFX for 6 months, HCRU was reduced and work productivity and activity increased.

Towards the Establishment of a Biomedical Ontology for the Primary Sjögren's Syndrome

Primary Sjögren's Syndrome (pSS) has been characterized as a hypersensitivity reaction type II systemic autoimmune chronic disease causing exocrine gland dysfunction mainly affecting women near the menopausal age. pSS patients exhibit dryness of the main mucosal surfaces and are highly prone to lymphoma development. This paper presents a first biomedical ontology for pSS based on a reference model which was determined by pSS clinical experts. The ensuing ontology constitutes the fundamental basis for mapping pSS-related ontologies from international cohorts to a common ontology. The ontology mapping (i.e., schematic interlinking) procedure is, in fact, a preliminary step to harmonize heterogeneous medical data obtained from various cohorts.

Self-Reported Work Ability Predicts Rehabilitation Measures, Disability Pensions, Other Welfare Benefits, and Work Participation: Longitudinal Findings from a Sample of German Employees

Purpose The study examined the performance of the Work Ability Index in predicting rehabilitation measures and disability pensions, sickness absence and unemployment benefits, and work participation among a sample of workers previously receiving sickness absence benefits. Methods Workers aged 40 to 54 years who received sickness absence benefits in 2012 completed the Work Ability Index in 2013. Outcomes were extracted from administrative data records. Results Data for 2149 participants were included (mean age: 47.8 years; 54.4% women). Mean follow-up was 19 months. Work Ability Index scores were poor (7-27 points) in 21% of the participants, and moderate (28-36 points) in 38.4%. In all, 224 rehabilitation measures and 35 disability pensions were approved. Fully adjusted analyses showed increased risk of rehabilitation measures in workers with poor (HR 4.55; 95% CI 3.14-6.60) and moderate scores (HR 2.08; 95% CI 1.43-3.01) compared to workers with good or excellent scores (37-49 points). The risk of a disability pension increased significantly for workers with poor scores (HR 7.78; 95% CI 2.59-23.35). In addition, poor scores were prospectively associated with a longer duration of sickness absence and employment benefits, and fewer employment days and less income from regular employment. Conclusions The Work Ability Index is a potential tool for following up workers who already have an increased risk of permanent work disability due to previous long-term sickness absence.

Work participation in spondyloarthritis across countries: analysis from the ASAS-COMOSPA study

OBJECTIVES

To explore the role of individual and country level socioeconomic (SE) factors on employment, absenteeism and presenteeism in patients with spondyloarthritis (SpA) across 22 countries worldwide.

METHODS

Patients with a clinical diagnosis of SpA fulfilling the ASAS classification criteria and in working age (≤65 years) from COMOSPA were included. Outcomes of interest were employment status, absenteeism and presenteeism, assessed by the Work Productivity and Activity Impairment Specific General Health questionnaire. Three multivariable models were built (one per outcome) using mixed-effects binomial (for work status) or ordinal regressions (for absenteeism and presenteeism), with country as random effect. The contribution of SE factors at the individual-level (eg, gender, education, marital status) and country-level (healthcare expenditure (HCE) per capita, Human Development Index (HDI) and gross domestic product per capita) SE factors, independent of clinical factors, was assessed.

RESULTS

In total, 3114 patients with SpA were included of which 1943 (62%) were employed. Physical function and comorbidities were related to all work outcomes in expected directions and disease activity also with absenteeism and presenteeism. Higher education (OR 4.2 (95% CI 3.1 to 5.6)) or living in a country with higher HCE (OR 2.3 (1.5 to 3.6)) or HDI (OR 1.9 (1.2 to 3.3)) was positively associated with being employed. Higher disease activity was associated with higher odds for absenteeism (OR 1.5 (1.3 to 1.7)) and presenteeism (OR 2.1 (1.8 to 2.4)). No significant association between individual-level and country-level SE factors and absenteeism or presenteeism was found.

CONCLUSIONS

Higher education level and higher country SE welfare are associated with a higher likelihood of keeping patients with SpA employed. Absenteeism and presenteeism are only associated with clinical but not with individual-level or country-level SE factors.

Effect of subcutaneous tocilizumab treatment on work/housework status in biologic-naïve rheumatoid arthritis patients using inverse probability of treatment weighting: FIRST ACT-SC study

BACKGROUND

Following the onset of rheumatoid arthritis (RA), patients experience a functional decline caused by various joint symptoms which affects their activities of daily living and can lead to reduced work productivity. We evaluated the effect of a 52-week treatment with tocilizumab by subcutaneous injection (TCZ-SC) among biologic-naive Japanese house workers (HWs) and paid workers (PWs) with RA in a real-world clinical practice.

METHODS

This multicenter, observational, prospective study enrolled 377 and 347 RA patients into TCZ-SC and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs)-alone groups, respectively. The primary endpoint was the change in percentage of overall work impairment (OWI) among PWs at week 52 assessed using the Work Productivity and Activity Impairment Questionnaire (WPAI). Inverse probability of treatment weighting analyses were used to compare treatments. The Work Functioning Impairment Scale, disease activity, quality of life (QOL) measures, and safety were also assessed.

RESULTS

The weighted change in OWI from baseline for PWs was -18.9% (TCZ-SC group) and -19.0% (csDMARDs group) at week 52, without a significant between-group difference (adjusted treatment difference 0.1, 95% confidence interval (CI) -6.3 to 6.5; P = 0.978). Changes in WPAI activity impairment in the overall group (between-group difference -6.4, 95% CI -10.7 to -2.2; P = 0.003) and HWs (-9.5, 95% CI - 16.0 to -2.9; P = 0.005) were significantly better with TCZ-SC than with csDMARDs at week 52. TCZ-SC-treated HWs showed significant improvement in all QOL assessments (Frenchay Activities Index, EuroQol 5 Dimension (EQ-5D), Japanese Health Assessment Questionnaire Disability Index (HAQ-DI), and 6-item Kessler scale (K6)) at week 52; PWs did not show any between-group differences for these QOL measures. Disease activity (Disease Activity Score 28-erythrocyte sedimentation rate, Clinical Disease Activity Index, and Simplified Disease Activity Index) and QOL measures (EQ-5D, HAQ-DI, and K6) improved over time in the overall group. No new safety concerns were raised with TCZ-SC.

CONCLUSIONS

Despite the lack of differences in OWI between groups at week 52, the overall group (particularly HWs) receiving TCZ-SC in addition to csDMARDs showed significant improvements in activity impairment, disease activity, and QOL versus those receiving csDMARDs alone. This study may promote the evaluation of work productivity improvements in HWs and PWs by RA treatment.

Exploring the personal burden of shoulder pain among younger people in Australia: protocol for a multicentre cohort study

INTRODUCTION

Persistent musculoskeletal conditions can impact profoundly on younger people's quality of life, psychological distress and capacity to work, as shown by previous research involving younger people with osteoarthritis. The personal impacts, in particular, work and parenting impacts, of other musculoskeletal conditions (such as persistent shoulder pain) on younger patient groups remain poorly understood. Furthermore, the personal financial burden associated with managing musculoskeletal conditions is rarely documented. This study aims to investigate well-being, work participation and productivity, shoulder-related parenting disability and out-of-pocket healthcare expenditure among younger people with shoulder pain and evaluate changes over 12 months.

METHODS AND ANALYSIS

One hundred and fifty people aged 20-55 years with shoulder pain of more than 6 weeks' duration (excluding those with recent history of fracture or dislocation) will be recruited for this cohort study. Participants will be recruited from three major public hospitals in Victoria, Australia, following screening of orthopaedic outpatient clinics lists and referrals. Participants will be asked to complete a baseline questionnaire and 2-week healthcare costs diary, with follow-up data collected at 12 months. Patient-reported outcomes will be collected, including health-related quality of life (HRQoL), shoulder pain and function, psychological distress, shoulder-related parenting disability and work productivity. Information on sociodemographics, employment, health services utilisation and shoulder-related healthcare expenditure will also be collected. Descriptive analysis of baseline data will provide a comprehensive snapshot of the personal burden of shoulder pain. Baseline HRQoL and psychological distress data will be compared with Australian population norms to provide context around well-being. Associations between sociodemographic factors and patient-reported outcomes will be evaluated using univariate and multivariate analyses. Changes in patient-reported outcomes from baseline to 12 months will be analysed using paired t-tests.

ETHICS AND DISSEMINATION

Ethics approval has been obtained. The study findings will be submitted to peer-reviewed journals and presented at relevant scientific meetings.
