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

A prospective cohort study of presenteeism and increased risk of unemployment among Japanese workers during the COVID-19 pandemic

OBJECTIVES

Presenteeism adversely affects workers' quality of life, leading to further deterioration of their health and affecting their ability to continue working. Unemployment is one of the most serious consequences for workers experiencing presenteeism. A worker's ability to work depends on the degree of mismatch between their health status and job demands and work factors. The COVID-19 pandemic has affected workers' experiences of presenteeism as well as their employment status. We examined the association between presenteeism and risk of job resignations and unemployment among Japanese workers during the COVID-19 pandemic.

METHODS

A prospective study of 27 036 internet monitors was conducted, starting in December 2020, with 18 560 (68.7%) participating in the follow-up by December 2021. The Work Functioning Impairment Scale (WFun) was used to measure the degree of work function impairment.

RESULTS

The group with the highest WFun scores had higher odds ratios (ORs) for both retirement and unemployment for health reasons than the group with the lowest WFun scores. ORs were 2.99 (95% CI, 2.48-3.62; P < .001) and 1.82 (95% CI, 1.65-2.00; P < .001), respectively.

CONCLUSIONS

Workers with work functioning impairment are at increased risk of resignation or unemployment. Management strategies for workers with work functioning impairment are needed to reduce their disadvantages in employment.

Challenges in the Management of Psoriatic Arthritis in Latin America: A Systematic Review

PURPOSE

In 2020, the International League of Associations for Rheumatology published recommendations for managing psoriatic arthritis (PsA), aiming to adapt the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis and the European Alliance of Associations for Rheumatology recommendations to low-income countries. At that time, the paucity of clinical studies examining the management of patients with PsA in Latin America was remarked on by the international working group. Therefore, the primary objective of this systematic literature review was to investigate the main challenges in managing PsA in Latin America as described in recent publications.

METHODS

A systematic literature review of trials reporting at least one challenge/difficulty in the management of PsA in Latin America was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. References published in the PubMed, EMBASE, and LILACS (Latin American and Caribbean Health Sciences Literature) databases between 1980 and February 2023 were included. The selection of references was conducted independently by 2 researchers in the Rayyan Qatar Computing Research Institute program. Two other reviewers independently extracted data. All challenges were noted and categorized into domains. Data analysis was descriptive.

FINDINGS

The search strategy yielded 2085 references, with 21 studies included in the final analysis. Most studies were conducted in Brazil (66.6%; n = 14) and were observational studies (100%; N = 21). Difficulties faced by PsA patients and physicians included the high incidence of opportunistic infections (described in 42.8% of the publications; n = 9), followed by nonadherence to therapy, discordance between patients and physicians regarding remission rates, low drug persistence, limited access to disease-modifying antirheumatic drugs, issues related to the storage of biologic drugs, elevated cost of biologic drugs, limited access to medical care, diagnostic delay, and the individual- and country-level impact of socioeconomic factors on work- and health-related outcomes.

IMPLICATIONS

Challenges in the management of PsA in Latin America extend beyond the care of opportunistic infections, encompassing several other socioeconomic factors. More research is needed to better understand the peculiarities of treating PsA in Latin America to improve patient care. PROSPERO identifier: CRD42021228297.

2021 EULAR points to consider to support people with rheumatic and musculoskeletal diseases to participate in healthy and sustainable paid work

AIM

As part of its strategic objectives for 2023, EULAR aims to improve the work participation of people with rheumatic and musculoskeletal diseases (RMDs). One strategic initiative focused on the development of overarching points to consider (PtC) to support people with RMDs in healthy and sustainable paid work participation.

METHODS

EULAR's standardised operating procedures were followed. A steering group identified six research areas on paid work participation. Three systematic literature reviews, several non-systematic reviews and two surveys were conducted. A multidisciplinary taskforce of 25 experts from 10 European countries and Canada formulated overarching principles and PtC after discussion of the results of literature reviews and surveys. Consensus was obtained through voting, with levels of agreement obtained anonymously.

RESULTS

Three overarching principles and 11 PtC were formulated. The PtC recognise various stakeholders are important to improving work participation. Five PtC emphasise shared responsibilities (eg, obligation to provide active support) (PtC 1, 2, 3, 5, 6). One encourages people with RMDs to discuss work limitations when necessary at each phase of their working life (PtC 4) and two focus on the role of interventions by healthcare providers or employers (PtC 7, 8). Employers are encouraged to create inclusive and flexible workplaces (PtC 10) and policymakers to make necessary changes in social and labour policies (PtC 9, 11). A research agenda highlights the necessity for stronger evidence aimed at personalising work-related support to the diverse needs of people with RMDs.

CONCLUSION

Implementation of these EULAR PtC will improve healthy and sustainable work participation of people with RMDs.

Poor work outcomes in patients with spondyloarthritis: causes, consequences, and solutions

BACKGROUND

Spondyloarthritis (SpA) affects patients in the prime of their economic productivity and can cause loss of work productivity and unemployment. We aim to identify factors associated with poor work outcomes in patients with SpA.

METHODS

A cross-sectional study was performed in 100 patients with SpA who were employed, retired, or off work because of SpA. Data on sociodemographic and professional characteristics were collected as well as specific indices: BASDAI, ASDAS-CRP, BASFI, and BASMI. Work productivity in employed patients was assessed by the Work Productivity and Activity Impairment scale (WPAI:SpA).

RESULTS

Patients were divided into 73 men and 27 women; the mean age was 43.68 ± 10.3 years. Fifty-nine percent of patients were employed and 26% were off work. The average disease duration was 12.24 ± 8.73 years. The mean BASDAI score was 4.4 ± 2.4, the average BASFI score was 4.6 ± 2.7, and the average ASDAS-CRP score was 2.77 ± 1.18. The mean BASMI was 4.4 ± 2.8. Among employed patients, the mean of absenteeism, presenteeism, and work productivity loss was 21.8 ± 33.13%, 42 ± 32%, and 46.5 ± 35.31%, respectively. In multivariable analysis, absenteeism was associated with ASDAS ≥ 2.1 (β = 20.14), peripheral joint involvement (β = 15.6), manual work (β = 14.31), low level of education (β = 7.92), and BASFI ≥ 4 (β = 6.39). Presenteeism and work productivity loss were associated with manual work, BASFI ≥ , body mass index ≥ 25 kg/m², smoking, the use of symptomatic treatment, and ASDAS-CRP ≥ 2.1.

CONCLUSION

Spondyloarthritis affects work productivity. Screening for predictive factors should be considered by the clinician in the overall management of the disease. Key Points • SpA occurs among young and active patients; it could affect their professional lives and thus lead to loss of work productivity and unemployment. • The management of patients with SpA must be multidisciplinary; this includes assessing contextual factors in order to act on modifiable factors such as smoking and BMI, optimal management of the disease to maintain at least a low disease activity, and to ensure workstation layout and elimination of professional constraints that can affect work outcomes in patients with SpA.

Development of an environmental contextual factor item set relevant to global functioning and health in patients with axial Spondyloarthritis

OBJECTIVE

To describe the development of an Environmental contextual factors (EF) Item Set (EFIS) accompanying the disease specific Assessment of SpondyloArthritis international Society Health Index (ASAS HI).

METHOD

First, a candidate item pool was developed by linking items from existing questionnaires to 13 EF previously selected for the ICF/ASAS Core Set. Second, using data from two international surveys, which contained the EF item pool as well as the items from the ASAS HI, the number of EF-items was reduced based on the correlation between the item and the ASAS HI sum score combined with expert opinion. Third, the final English EFIS was translated into 15 languages and cross-culturally validated.

RESULTS

The initial item pool contained 53 EF addressing 4 ICF EF-chapters: products and technology (e1), support and relationship (e3), attitudes (e4) and health services (e5). Based on 1754 responses of axial spondyloarthritis patients in an international survey, 44 of 53 initial items were removed based on low correlations to the ASAS HI or redundancy combined with expert opinion. 9 items of the initial item pool (range correlation 0.21-0.49) form the final EFIS. The EFIS was translated into 15 languages and field tested in 24 countries.

CONCLUSIONS

An EFIS is available complementing the ASAS HI and helps to interpret the ASAS HI results by gaining an understanding of the interaction between a health condition and contextual factors. The EFIS emphasizes the importance of support and relationships, as well as attitudes of the patient and health services in relation to self-reported health.

EULAR Points to Consider (PtC) for designing, analysing and reporting of studies with work participation as an outcome domain in patients with inflammatory arthritis

BACKGROUND

Clinical studies with work participation (WP) as an outcome domain pose particular methodological challenges that hamper interpretation, comparison between studies and meta-analyses.

OBJECTIVES

To develop Points to Consider (PtC) for design, analysis and reporting of studies of patients with inflammatory arthritis that include WP as a primary or secondary outcome domain.

METHODS

The EULAR Standardised Operating Procedures were followed. A multidisciplinary taskforce with 22 experts including patients with rheumatic diseases, from 10 EULAR countries and Canada, identified methodologic areas of concern. Two systematic literature reviews (SLR) appraised the methodology across these areas. In parallel, two surveys among professional societies and experts outside the taskforce sought for additional methodological areas or existing conducting/reporting recommendations. The taskforce formulated the PtC after presentation of the SLRs and survey results, and discussion. Consensus was obtained through informal voting, with levels of agreement obtained anonymously.

RESULTS

Two overarching principles and nine PtC were formulated. The taskforce recommends to align the work-related study objective to the design, duration, and outcome domains/measurement instruments of the study (PtC: 1-3); to identify contextual factors upfront and account for them in analyses (PtC: 4); to account for interdependence of different work outcome domains and for changes in work status over time (PtC: 5-7); to present results as means as well as proportions of patients reaching predefined meaningful categories (PtC: 8) and to explicitly report volumes of productivity loss when costs are an outcome (PtC:9).

CONCLUSION

Adherence to these EULAR PtC will improve the methodological quality of studies evaluating WP.

Sick leave in early axial spondyloarthritis: the role of clinical and socioeconomic factors. Five-year data from the DESIR cohort

OBJECTIVES

To investigate the occurrence of sick leave (SL) and the impact of clinical and socioeconomic factors on SL in early axial spondyloarthritis (axSpA).

METHODS

Patients with a clinical diagnosis of axSpA from the DEvenir des Spondyloarthrites Indifférenciées Récentes (DESIR) cohort with work-related data and up to 5-year follow-up were studied. Incidence, time to first SL and potential role of baseline and time-varying clinical and socioeconomic factors (age, gender, ethnicity, education, job type, marital and parental status) were analysed. Univariable analyses, followed by collinearity and interaction tests, guided subsequent multivariable time-varying Cox survival model building.

RESULTS

In total, 704 axSpA patients were included (mean (SD) age 33.8 (8.6); 46% men). At baseline, 80% of patients were employed; of these, 5.7% reported being on SL. The incidence of SL among those at risk during the study period (n=620, 88%) was 0.05 (95% CI 0.03 to 0.06) per 1000 days of follow-up. Mean (SD) time to first SL was 806 (595) days (range: 175-2021 days). In multivariable models, male gender (HR 0.41 (95% CI 0.20 to 0.86)) and higher education (HR 0.48 (95% CI 0.24 to 0.95)) were associated with lower hazard of SL, while higher disease activity (HR 1.49 (95% CI 1.04 to 2.13)), older age, smoking and use of tumour necrosis factor inhibitors were associated with higher hazard of SL.

CONCLUSIONS

In this early axSpA cohort of young, working-age individuals, male gender and higher education were independently associated with a lower hazard of SL, whereas older age and higher disease activity were associated with higher hazard of SL. The findings suggest a role of socioeconomic factors in adverse work outcomes, alongside active disease.

Association between individual and country-level socioeconomic factors and work participation in spondyloarthritis including psoriatic arthritis: Analysis of the ASAS-perSpA study

OBJECTIVE

To examine whether associations between socioeconomic factors and work outcomes in spondyloarthritis (SpA) differ across axial (axSpA), peripheral SpA (pSpA) and psoriatic arthritis (PsA), and whether associations for individual-level socioeconomic factors are modified by country-level factors.

METHODS

Patients with a physician diagnosis of SpA within working age (18-65 years) were included. Associations between individual- (age, gender, education, marital status) and country-level factors (Human Development Index, Health Care Expenditure (HCE), Gross Domestic Product, percentage unemployed) with work outcomes (employment status, absenteeism, presenteeism) were assessed using multivariable mixed-effects models. Associations between individual factors and outcomes were compared according to SpA phenotypes and country-level factors using interaction terms.

RESULTS

A total of 3835 patients (mean age 42 years, 61% males) from 23 countries worldwide were included (66% axSpA, 10% pSpA, 23% PsA). Being employed was associated with gender (male vs. female OR 2.5; 95%CI 1.9-3.2), education (university vs. primary OR 3.7; 2.9-4.7), marital status (married vs. single OR 1.3; 1.04-1.6), and age in a non-linear manner. University (vs primary) education was associated with lower odds of absenteeism (OR 0.7; 0.5-0.96) and presenteeism (OR 0.5; 0.3-0.7). Associations were similar across SpA phenotypes. Higher HCE was associated with more favourable work outcomes, e.g., higher odds of employment (OR 2.5; 1.5-4.1). Gender discrepancy in odds of employment was greater in countries with lower socioeconomic development.

CONCLUSION

Higher educational attainment and higher HCE were associated with more favourable work outcomes, independently of SpA phenotype. The disadvantageous effect of female gender on employment is particularly strong in countries with lower socioeconomic development.

Prediction of Work Impact in Axial Spondyloarthritis by the Work Instability Scale: A Prospective Cohort Study of 101 Patients

OBJECTIVE

Axial spondyloarthritis (axSpA) may have an effect on work. The Ankylosing Spondylitis Work Instability Scale (AS-WIS) assesses difficulties at work. The objective of this study was to evaluate the predictive value of the AS-WIS on work impact.

METHODS

This is a prospective cohort study with 2 timepoints (at baseline and after 1.5 yrs) that included patients with axSpA who had paid employment. Patients completed the AS-WIS at baseline and work instability was scored as moderate/high if ≥ 11 (0-20 scale). At follow-up, adverse work outcomes (AWO) were grouped as moderate (short-term sick leave) or severe AWO (long-term sick leave, disability, unemployment). Univariable and multivariable logistic regression analyses were performed to explain AWO.

RESULTS

Of 101 patients, mean age 45 (SD 9) years, 52% male, disease duration was 14 (SD 8) years. The Bath AS Disease Activity Index and the Bath AS Functional Index were 34 (SD 21) and 23 (SD 23), respectively, and 69 (68%) received a tumor necrosis factor inhibitor. At baseline, 46 (46%) patients had moderate/high AS-WIS. At 1.5 years of follow-up, 37 patients (36%) had AWO: 25 patients (25%) a short-term sick leave, and 12 patients (12%, 7/100 patient-years) a severe AWO. Independent baseline factors associated with AWO were a moderate/high AS-WIS score (OR 2.71, 95% CI 1.04-7.22) and shorter disease duration (OR 0.94, 95% CI 0.89-0.99).

CONCLUSION

In patients with axSpA, a moderate/high AS-WIS score was predictive of AWO in this population with well-controlled axSpA. This short questionnaire can be helpful to screen for future difficulties at work.

Patients with axial spondyloarthritis report significant differences between men and women and high impact of the disease: Large websurvey analysis

OBJECTIVE

In axial spondyloarthritis (axSpA), mounting evidence shows female patients to experience a higher disease burden. These differences appear to be particularly large in South America. One explanation could be inequity in treatment access between men and women. The objective was to evaluate gender differences in disease burden and work participation, and the potential influence of treatment, in Latin American patients.

METHODS

A cross sectional online survey among axSpA patients, collecting disease characteristics, treatment, disease burden (BASDAI, BASFI, ASAS Health Index) and work participation (WPAI). Associations between gender and disease burden or work participation were assessed through regression analyses, correcting for treatment.

RESULTS

AxSpA was reported by 472 participants (63% women) and disease activity (BASDAI≥4: 83%), ASASHI (≥moderately impaired: 91%) and work disability (absenteeism: 41%; presenteeism 82%) were high. Biological use was very low (20%), while 34% used opiates. Females had significantly higher BASDAI, ASAS HI, work absenteeism and presenteeism, although were less likely to receive biologics (26% versus 16%, P<0.01). Gender differences disappeared after correction for treatment.

CONCLUSIONS

This web survey in Latin American axSpA patients shows a high disease burden and work impairment. The use of biologics is low, while the use of opiates was alarmingly high. Women used significantly less biologics despite reporting a worse disease state and work disability, which could be due to treatment inequity.

Measuring outcomes in ankylosing spondylitis: pearls and pitfalls

PURPOSE OF REVIEW

Patients with ankylosing spondylitis (AS) warrant a comprehensive clinical assessment because of the lack of biomarkers of disease activity, prognosis and response to biologic therapy. Multiple AS-related questionnaires have been developed to assess the disease status accurately, but feasibility remains a problem in clinical practice. The purpose of this review is to assess the pearls and pitfalls of AS-related outcome measures.

RECENT FINDINGS

Single-item questionnaires to measure pain, stiffness and fatigue in patients with AS are easily administrable but may lack a sufficient degree of responsiveness on an individual patient level. The Bath Ankylosing Disease Activity Index remains the gold standard for assessing disease activity in a routine practice, despite poor correlation with C-reactive protein (CRP) levels and MRI inflammation. The Ankylosing Spondylitis Disease Activity Score, a validated and highly discriminatory tool for assessing disease activity in AS, has been developed but lacks feasibility as erythrocytic sedimentation rate and CRP values are often not available during a clinic visit. RAPID-3 appears feasible to assess patients with AS quantitatively over time in busy clinical settings.

SUMMARY

The assessment of disease status in AS is complex and is impacted by multiple factors. The biggest challenge in AS is to incorporate the disease-specific indices into a routine practice. VIDEO ABSTRACT: http://links.lww.com/COR/A42.

Short-term response in new users of anti-TNF predicts long-term productivity and non-disability: analysis of Czech ATTRA ankylosing spondylitis biologic registry

Objectives: To assess the role of short-term response to first anti-TNF in long-term prediction of disability.Methods: In nationwide registry ATTRA, we identified ankylosing spondylitis patients starting anti-TNF between 01/2003 and 12/2016. Full disability and work impairment (WI; WPAI questionnaire) were predicted via the Cox- and lagged-parameter mixed-effect regression.Results: 2,274 biologicals-naïve patients newly indicated to anti-TNF were prospectively followed (6,333 patient-years; median follow-up 1.9 years). Reaching BASDAI < 4 (77.4%) and ASDAS-CRP < 2.1 (61.1%) after 3 months of anti-TNF both decreased the risk of future disability by ≈2.5-fold. ASDAS-CRP < 2.1 predicted non-disability better than BASDAI < 4 & CRP < 5 mg/L (p = 0.032). BASDAI < 4 & CRP < 5 mg/L was comparable to BASDAI < 4 (p = 0.941) and to BASDAI change by >50% or by >2 points (p = 0.902). ASDAS-CRP change >1.1 and >2.0 both failed to predict non-disability. Once on anti-TNF therapy, the strongest predictor of WI was Pain (SF36). Yearly increase in indirect costs remains below €3,000 in those reaching ASDAS-CRP < 2.1.Conclusions: Low disease activity measured by ASDAS-CRP ≤ 2.1 should be used to measure the outcome of new anti-TNF therapy. Continuous WI could be decreased through pain management.
