[Translated article] Temporary work disability following trapezial resection and suspension arthroplasty for thumb carpometacarpal osteoarthritis

PurposeThe aim of this study is to assess the time to return to work (TRW) in patients undergoing trapezial resection using the Mini TightRope® system at our centre and to investigate factors that might delay return to work following this surgery. Material and methodsA retrospective study was conducted on patients who underwent Trapezial resection and suspensionplasty using the Mini TightRope® system between 2015 and 2016, with a minimum one-year follow-up. Telephone interviews were conducted along with a review of medical records and radiology reports, as well as temporary work disability documents, collecting epidemiological and occupational data. Groups were compared based on age, gender, dominant hand, biomechanical occupational requirements of the patients, and whether they had experienced prior temporary work disability. ResultsA total of 36 patients (29 women and 7 men) with an average age of 55.7 years were included. The median time to return to work was 126 days. Self-employed workers re-entered the workforce 72 days earlier on average; workers who had experienced prior temporary work disability had a greater total temporary work disability duration and took 91 days longer to return to work compared to those who had not. ConclusionsPatients employed by others and those who had experienced prior temporary work disability before the surgery had longer temporary work disability periods. In our study, no differences were observed based on gender, dominant hand, or biomechanical work demands of the intervened patients.

How Much Physiotherapy, Chiropractic, and Osteopathy Care Do Compensated Australian Workers with Low Back Pain Receive? A Retrospective Cohort Study.

To identify the prevalence and frequency of physiotherapy, chiropractic, and/or osteopathy care in Australians with workers' compensation claims for low back pain (LBP). We included workers with accepted workers' compensation claims longer than 2weeks from the Australian states of Victoria, Queensland, South Australia, and Western Australia. Workers were grouped by whether they attended physiotherapy, chiropractic, and/or osteopathy in the first 2years of their claim. Descriptive statistics and logistic regression were used to describe differences between groups. Descriptive statistics and negative binomial regression were used to describe differences in the number of attendances in each group. Most workers had at least one physical therapy attendance during the period of their claim (n = 23,619, 82.0%). Worker state, socioeconomic status, and remoteness were the largest contributing factors to likelihood of physical therapy attendance. Most workers only attended physiotherapy (n = 21,035, 89.1%, median of 13 times). Far fewer only attended chiropractic (n = 528, 2.2%, median of 8 times) or only osteopathy (n = 296, 1.3%, median of 10 times), while 1,750 (7.5%) attended for care with more than one type of physical therapy (median of 31 times). Most Australian workers with workers' compensation time loss claims for LBP attend physiotherapy at least once during their claims. State of claim is the strongest predictor of which physical therapy profession they attend, possibly due to regional availability. Workers who see a physiotherapist have significantly more attendances. Future research should explore the relationship between these patterns of care and claimant outcomes, including work disability duration.

Psychotherapy duration and work disability: A prospective Finnish register study.

The influence of psychotherapy duration on common mental disorder (CMD) outcomes remains a topic of ongoing debate. Whereas most research has focused on CMD symptom change, the evidence on the psychotherapy duration of subsequent CMD-related work disability and the change in psychotropic drug purchases is scarce. We used a register-based cohort representing 33% of the Finnish population. The participants included working-age individuals (N = 12,047, 76% women, mean age = 36) who initiated long-term psychotherapy, between 2014 and 2017. They were followed from 2011 to 2021 and psychotherapy duration ranged from less than a year to over 3 years. We used an interrupted time series design to analyze the psychotherapy duration-dependent changes in CMD-related work disability (primary outcome, operationalized as depression or anxiety-related sickness absence, SA, days) and the annual number of psychotropic drug purchases or distinct drugs purchased (secondary outcomes). There were no differences in the levels of work disability or drug purchases before the psychotherapy. We observed a decreasing level and trend in all outcomes across all psychotherapy duration groups. The largest decline in level was observed in the <1-year duration group (88% decline for SA and 43%-44% for drug purchases) while the smallest decline was in the 3+ years duration group (73% for SA and 27% for drug purchases). Work disability outcomes and duration varied among individuals, even with similar initial mental health-related work disability or use of auxiliary psychotropic treatments. Compared to longer psychotherapy, shorter psychotherapy was associated with sharper improvements.

In our study, no differences were observed based on gender, dominant hand, or biomechanical work demands of the intervened patients.

Work Disability Duration Among Mobile Workers: Does Intraprovincial Mobility Matter as Much as Interprovincial Mobility?

The aim of the study is to compare work disability duration of intraprovincially and interprovincially mobile workers with nonmobile workers in British Columbia, Canada. Workers' compensation claims were extracted for workers injured between 2010 and 2019. Employer and residential postal codes were converted to economic regions to define nonmobile, intraprovincially, and interprovincially mobile workers. Quantile regression models using matched cohorts were used to estimate differences in work disability days at different percentiles of the distribution. Compared with nonmobile workers, both mobile worker groups had longer work disability durations, particularly interprovincially mobile workers. Differences persisted in injury-stratified models and were partially or fully attenuated in some industry-stratified models. Workers' compensation systems, employers, and healthcare providers may need to tailor specific interventions for mobile workers who are from out-of-province as well as traveling between regions in the province.

Economic impact of work disability due to chronic low back pain from the patient perspective

ObjectivesLow back pain (LBP) is one of the main expenditure items for health systems. Data on the economic impact of LBP are uncommon from the patient perspective. The aim of this study was to estimate the economic impact of work disability related to chronic LBP from the patient perspective. MethodsWe conducted a cross-sectional analysis from patients aged over 17 years suffering from non-specific LBP for at least 3 months. Systematic medical, social and economic assessments were collected: pain duration and intensity; functional disability with the Quebec Back Pain Disability Scale (0–100); quality of life with the Dallas Pain Questionnaire; job category; employment status; duration of work disability due to LBP, and income. Factors associated with loss of income were identified by multivariable logistic regression analysis. ResultsWe included 244 workers (mean age 43 ± 9 years; 36% women); 199 patients had work disability, including 196 who were on sick leave, 106 due to job injury. Three were unemployed due to layoff for incapacity. The mean loss of income for patients with work disability was 14% [SD 24, range −100 to 70] and was significantly less for patients on sick leave due to job injury than on sick leave not related to job injury (p < 0.0001). On multivariable analysis, the probability of loss of income with LBP was about 50% less for overseers and senior managers than workers or employees (odds ratio 0.48 [95% confidence interval 0.23–0.99]). ConclusionWork disability due to LBP resulted in loss of income in our study. The loss of income depended on the type of social protection and job category. It was reduced for patients on sick leave related to work injury and for overseers and senior managers.

Do regional labor market conditions matter for temporary work disability duration? A multilevel analysis of workers' compensation claims in five Canadian provinces.

Research has shown how regionally varying labor market conditions are associated with differences in work disability duration. However, the majority of these studies have not used multilevel models to appropriately account for the hierarchical clustering of individuals nested within contextual units (e.g., regions). Studies that have used multilevel models have focused on privately insured workers or on disability not specifically caused by work-related injury or illness. Using claims data from five Canadian provincial workers' compensation systems, linear random-intercept models were used to estimate how much variance in temporary work disability duration ('work disability duration' for brevity) for work-related injuries and musculoskeletal disorders was due to differences between economic regions, what economic region-level labor market characteristics were associated with work disability duration, and what characteristics best explained economic region differences in work disability duration. Economic region characteristics, such as the unemployment rate and proportion of goods-producing employment, were independently associated with individual-level work disability duration. However, economic region variation only accounted for 1.5%-2% of total variation in work disability duration. The majority (71%) of economic region-level variation was explained by the provincial jurisdiction where the worker livedand was injured. Regional variation tended to be greater for female workers than males. The findings suggest that while regional labor market conditions matter for work disability duration, system-level differences in workers' compensation and health care are more important factors influencing work disability duration. Furthermore, while this study includes both temporary and permanent disability claims, the work disability duration measure only captures temporary disability.

The relationship between work disability and subsequent suicide or self-harm: A scoping review.

Work disability occurs when an injury or illness limits the ability of a worker to participate in employment. While evidence suggests that people with work disability are at increased risk of suicide and intentional self-harm, this relationship has not been the subject of systematic review. This scoping review aims to assess and summarise the research literature regarding the relationship between work disability and subsequent suicide or intentional self-harm. Review protocol was published on the Open Science Foundation and is reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Peer-reviewed studies published in English from 1st January 2000 were included if they reported suicide or self-harm outcomes in people aged 15 years or older with work disability. Studies were identified via systematic search of Medline, Scopus and Pubmed databases, via recommendation from topic experts, and citation searching of included articles. A narrative synthesis was undertaken. Literature search yielded 859 records of which 47 eligible studies were included, nine set in workers' compensation, 20 in sickness absence, 13 in disability pension systems, and five from mixed cohorts. Of 44 quantitative studies, 41 reported a positive relationship between work disability and suicidal behaviour. The relationship is observed consistently across nations, work disability income support systems and health conditions. Several factors elevate risk of suicidal behaviour, including presence of mental health conditions and longer work disability duration. There were few studies in some nations and no suicide prevention interventions. The risk of suicide and self-harm is elevated in people experiencing work disability. Further observational research is required to fill evidence gaps. This review suggests the need for governments, employers and those involved in the care of people with work disability to focus on identification and monitoring of those at greatest risk of suicidal behaviour, and suicide prevention.

Comparing treatment of proximal phalangeal fractures with intramedullary screws versus plating

PurposePhalangeal fractures are the most common injuries in humans and account for approximately 10% of all fractures. With plate fixation, anatomic reduction is achievable in most cases, but extension lag is seen in up to 67%. Intramedullary headless screw offers treatment of unstable proximal phalangeal fractures using a minimally invasive procedure with very few complications. One of the major disadvantages of this technique is the transarticular screw position, damaging the articular surface and thus preventing very proximal fractures from being treated with a distally inserted screw. In this study, we present a modified approach to the fixation of the proximal phalangeal fractures and compare outcomes with plate osteosynthesis.Materials and methodsTwenty-nine patients with 31 comparable fractures of the proximal phalanx were treated either with a plate (14) or with minimal invasive cannulated compression screw (17). Pain, strength, range of motion (ROM), work disability and QuickDASH score were assessed.ResultsTAM was significantly better in the screw group. The extension lag was worse in the plate group. Plate removal had to be performed in 13 of 14 the cases, while the screw had to be removed in only 3 cases. The average duration of work disability was 9.9 weeks in the plate group, compared to 5.6 weeks in the screw group.ConclusionMinimally invasive screw osteosynthesis not only has the advantage of significantly shorter work disabilities, but also shows remarkably improved postoperative range of motion. In contrast to plate osteosynthesis, removal of the screw is only necessary in exceptional cases. With the antegrade screws position, even difficult fractures close to the base can be treated without destroying any articular surface. In proximal phalanx fractures with both options of plate or single-screw osteosynthesis, we recommend minimal invasive cannulated screw osteosynthesis.

The Association Between Continuity of Care With a Primary Care Physician and Duration of Work Disability for Low Back Pain: A Retrospective Cohort Study.

The aims of the study are to determine the continuity of care (CoC) provided by primary care physicians among workers with low back pain, to identify factors associated with CoC, and to investigate whether CoC is associated with working time loss. Continuity of care was measured with the usual provider continuity metric. Ordinal logistic regression models examined factors associated with CoC. Quantile regression models examined the association between working time loss and CoC. Complete CoC was observed in 33.8% of workers, high CoC among 37.7%, moderate CoC in 22.1%, and low CoC in 6.4%. In workers with more than 2-months time loss, those with complete CoC had less time off work. Higher CoC with a primary care physician is associated with less working time loss and this relationship is strongest in the subacute phase of low back pain.

The Impact of Osteoporotic Fractures on Patients with Rheumatoid Arthritis in Work Disability

Osteoporosis is the one of most common chronic metabolic bone disease, which is characterized by increased bone fragility, which is highly affected by age and menopause.1 According to the International Osteoporosis Foundation, one in three women over the age of 50 experience at least once in a lifetime a fracture as a result of osteoporosis, which on another hand is a cause for work disability.2,3&#x0D; Objective: The purpose of the study is to evaluate the economic and social impact of work disability, caused by fractures as a result of osteoporosis on patients with RA.&#x0D; Material and Methods: The study included 50 patients, diagnosed with RA and osteoporosis, which have had at least one fracture during their course of disease. The data were obtained in the Regional Hospital of Elbasan and the main focus was the duration of work disability.&#x0D; Results: The research concluded that approximately 20% of the patients required a long term disability benefit after suffering a fracture. Furthermore, the majority of the patients were reluctant to go back to work after suffering the consequences of the fracture, mainly due to pain and inability to properly move.&#x0D; Conclusion: Fractures due to osteoporosis on patients with RA have an increasing impact in work disability and life quality. The majority of the patients taken into research have benefited from work disability policies, whether short or long-term.

Exploring Differences in Work Disability Duration by Size of Firm in Canada and Australia.

Purpose To identify whether there were differences in work disability duration between injured workers employed by small, medium, large, and self-insured firms and whether these differences varied between workers' compensation jurisdictions in Canada and Australia. Methods Workers' compensation data were used to identify comparable lost-time, work-related injury and musculoskeletal disorder claims in five Canadian and five Australian jurisdictions between 2011 and 2015. Work disability duration was measured using cumulative disability days paid up to one-year post-injury. Jurisdiction-specific quantile regression models were used to estimate differences in cumulative disability days paid to claims from small (< 20 full-time equivalents (FTEs)) medium (20-199 FTEs), large (200 + FTEs) and self-insured firms at the 25th, 50th, and 70th percentiles in the disability distribution, adjusting for confounders. Results Compared to large firms, workers in small firms generally had longer work disability duration at each percentile, particularly in Saskatchewan and Alberta (Canada), Victoria and Australian Capital Territory (Australia), where an additional 31.1, 18.4, 58.5 and 37.0days were paid at the 75th percentiles, respectively. The disability duration of workers from self-insured firms was longer than large firms in all Canadian jurisdictions but was shorter or no different in Australian jurisdictions. Smaller differences were observed between claims from large and medium-sized firms. Conclusions Workers in small firms had longer work disability duration than those in large firms in all but one of the study jurisdictions. Claims management processes need to be sensitive to the challenges that small firms face in accommodating and returning injured workers back to work.

Evaluating effectiveness of an integrated return-to-work and vocational rehabilitation program on work disability duration in the construction sector.

ObjectiveThe aim of this study was to investigate whether an integrated return-to-work (RTW) and vocational rehabilitation (VR) program – the Work Reintegration (WR) program – was associated with reduced work disability duration in the construction sector in Ontario, Canada.MethodsWorkers’ compensation data from the Ontario Workplace Safety and Insurance Board were extracted for lost-time construction worker claims following work-related injuries between 2009 and 2015. Claims receiving referrals to RTW and VR specialists (treatments) were matched with claims receiving no referrals (controls) during the periods before and after the WR program introduction. Multivariable difference-in-differences linear and quantile regression models were used to examine differences in cumulative disability days paid during two-years post-injury between treatment and control groups before and after the program change and the difference in these differences, overall, and at different disability distribution percentiles.ResultsThe WR program introduction was associated with reductions in cumulative disability days paid for all claims but most notably among longer duration claims referred to RTW specialists (reduction of 274 days at the 90th percentile in the disability distribution) and shorter duration claims referred to VR specialists (reductions of 255 and 214 days at the 25th and 50th percentiles in the disability distribution, respectively).ConclusionsThe WR program introduction was effective in reducing cumulative disability days paid for construction worker claims but the effects varied at different percentiles in the disability distribution, as well as by specialist referral. The findings highlight the benefits of better integrated RTW and VR services to injured workers in the construction sector.

Differences in Work Disability Duration for Immigrants and Canadian-Born Workers in British Columbia, Canada.

This study aimed to investigate differences in work disability duration among immigrants (categorized as economic, family member or refugee/other classification upon arrival to Canada) compared to Canadian-born workers with a work-related injury in British Columbia. Immigrants and Canadian-born workers were identified from linked immigration records with workers’ compensation claims for work-related back strain, connective tissue, concussion and fracture injuries requiring at least one paid day of work disability benefits between 2009 to 2015. Quantile regression investigated the relationship between immigration classification and predicted work disability days (defined from injury date to end of compensation claim, up to 365 days) and modeled at the 25th, 50th and 75th percentile of the distribution of the disability days. With a few exceptions, immigrants experienced greater predicted disability days compared to Canadian-born workers within the same injury cohort. The largest differences were observed for family and refugee/other immigrant classification workers, and, in particular, for women within these classifications, compared to Canadian-born workers. For example, at the 50th percentile of the distribution of disability days, we observed a difference of 34.1 days longer for refugee/other women in the concussion cohort and a difference of 27.5 days longer for family classification women in the fracture cohort. Economic immigrants had comparable disability days with Canadian-born workers, especially at the 25th and 50th percentiles of the distribution. Immigrant workers’ longer disability durations may be a result of more severe injuries or challenges navigating the workers’ compensation system with delays in seeking disability benefits and rehabilitation services. Differences by immigrant classification speak to vulnerabilities or inequities upon arrival in Canada that persist after entry to the workforce and warrant further investigation for early mitigation strategies.

Pain catastrophizing, kinesiophobia and fear-avoidance in non-specific work-related low-back pain as predictors of sickness absence.

The influence of pain catastrophizing, kinesiophobia and fear-avoidance attitudes towards non-specific low-back pain has been scarcely studied in an occupational insurance provider context. The objective of this work is to ascertain the relationship between these psychosocial variables with work absence, its duration and the disability of subjects with work-related low back pain. This is a descriptive observational methodological strategy. All patients with work-related non-specific low back pain who attended to an occupational health hospital during the study period were included consecutively. Clinical variables of kinesiophobia, pain catastrophizing, fear-avoidance attitudes, disability and pain were collected; sociodemographic variables of sex, age, type of work, educational level, occupational status and duration in days of work absence were recorded. Kinesiophobia (b = 1.43, P = 0.011, r = 0.333), fear-avoidance beliefs in its global dimension (b = 0.910, P = 0.014, r = 0.321), fear-avoidance beliefs in its work dimension (b = 1.255, P = 0.016, r = 0.321) and pain catastrophizing (b = 0.997, P = 0.013, r = 0.340) show individual association with the duration of sickness absence. Kinesiophobia (b = 0.821, P = 0.011, r = 0.30) and fear-avoidance beliefs (b = 1.760, P = 0.016, r = 0.28) are associated with disability (Kinesiophobia, b = 0.880, P = 0.045, r = 0.26; Fear-avoidance beliefs, b = 0.724, P = 0.010, r = 0.34). Kinesiophobia, fear-avoidance beliefs and pain catastrophizing are related to an increase in the duration of work absence and disability in patients with back pain in an occupational insurance provider context.

Challenges in Data Linkage – Experiences from An Upper Gastrointestinal Cancer Data Linkage Study

IntroductionNearly one quarter of a million Australian workers experience a work injury annually and make a benefit claim through one of the nation’s eleven workers’ compensation (WC) systems. The total cost to Australian society has most recently been estimated at $61.8 billion or 4.1% of GDP. The disaggregation of legislative responsibility between jurisdictions has contributed to a lack of common data standards, and thus minimal understanding of the efficiency or effectiveness of service provision in the Australian WC sector.&#x0D; Objectives and ApproachThis project developed a new multi-jurisdictional work disability database including detailed information on work disability duration, health and social care service provision. Service level payment data contained in structured WC insurance claims datasets held by five large WC jurisdictions with &gt;60% coverage of the Australian labour force was collected for all cases of work-related low back pain, fractures and limb soft tissue disease over between 2010 and 2015. Database development involved creation and coding of harmonised service-level indicators for individual episodes of healthcare provision and weekly periods of wage replacement.&#x0D; ResultsA total of 253,000 cases and 10.7 million service episodes are included in the database. Initial exploratory analyses focused on the frequency, prevalence, timing, intensity and continuity of General Practitioner (GP) services to each of the injury groups. Regression modelling examined occupational, injury, demographic and jurisdictional factors affecting GP service use outcomes. As anticipated, service patterns varied by injury type, age, gender and occupational group. Significant differences in service use between WC jurisdictions were observed.&#x0D; Conclusion / ImplicationsThis exploratory study demonstrates the feasibility of developing a population-based service level database for monitoring health service delivery to injured Australian workers. Future studies will examine the impact of jurisdictional policy differences on service delivery, and the relationship between service delivery and outcomes such as disability duration.
