Feasibility and sustainability of working in different types of jobs after total hip arthroplasty: analysis of longitudinal data from two cohorts.

OBJECTIVES: To investigate the rates of return to work and workability among working-age people following total hip arthroplasty (THA). METHODS: Participants from the Geneva Arthroplasty Registry and the Clinical Outcomes for Arthroplasty Study aged 18-64 years when they had primary THA and with at least 5 years' follow-up were mailed a questionnaire 2017-2019. Information was collected about preoperative and post-THA employment along with exposure to physically demanding activities at work or in leisure. Patterns of change of job were explored. Survival analyses using Cox proportional hazard models were created to explore risk factors for having to stop work because of difficulties with the replaced hip. RESULTS: In total, 825 returned a questionnaire (response 58%), 392 (48%) men, mean age 58 years, median follow-up 7.5 years post-THA. The majority (93%) of those who worked preoperatively returned to work, mostly in the same sector but higher rates of non-return (36%-41%) were seen among process, plant and machine operatives and workers in elementary occupations. 7% reported subsequently leaving work because of their replaced hip and the risk of this was strongly associated with: standing >4 hours/day (HR 3.81, 95% CI 1.62 to 8.96); kneeling/squatting (HR 3.32, 95% CI 1.46 to 7.55) and/or carrying/lifting ≥10 kg (HR 5.43, 95% CI 2.29 to 12.88). CONCLUSIONS: It may be more difficult to return to some (particularly physically demanding) jobs post-THA than others. Rehabilitation may need to be targeted to these types of workers or it may be that redeployment or job change counselling are required.

Function and employment after total hip replacement in older adults: A narrative review.

The burden of osteoarthritis (OA) has increased steadily due to an aging population, increasing life expectancy, obesity and lifestyle factors. Total hip replacement has become one of the most prevalent and successful operations globally and it is projected that demand will continue to grow as the incidence of OA continues to increase. Patients undergoing the operation expect much-improved function and pain relief but also increasingly need to return to work postoperatively, especially given the growing demand for the procedure and the encouragement of older people to continue working by most governments in the developed world. This review provides an overview of function and employment outcomes after hip arthroplasty. Despite the generally good success rate, some patients do not attain good functional outcomes and it is important that we develop ways to identify these patients preoperatively. We describe the effect of demographic, clinical and other factors on functional outcomes, as well as trajectories of physical function and pain recovery beyond the first few weeks after total hip replacement. Regarding employment outcomes, many people in work preoperatively are likely to resume to work after recovery; however, patients feel that they lack guidance from clinicians about returning to work postoperatively. Our review encompasses factors associated with return to work, timing of return to work, and potential temporary or permanent limitations that people might experience at work depending on type of employment.

Return to work and employment retention after uni-compartmental and total knee replacement: findings from the Clinical Outcomes in Arthroplasty study.

BACKGROUND: Little is known about ability to work after unicompartmental knee replacement (UKR) and total knee replacement (TKR), especially in physically-demanding occupations. This study described rates of return-to-work (RTW) and ability to sustain work by job after arthroplasty. METHOD: Participants from The Clinical Outcomes in Arthroplasty Study (COASt) aged 18-65 were eligible if they underwent UKR or TKR and had at least 5 years' follow-up post-operation. We posted a survey asking about pre-operative occupation, post-operative occupations and associated physical demands, and whether they had quit a job post-surgery due to difficulties with the operated knee (knee-related job loss (KRJL)). We fitted Cox Proportional Hazard Models to investigate the role of demanding physical activities on KRJL. RESULTS: 251 people (143 UKR, 108 TKR) returned a questionnaire, of whom 101 UKR and 57 TKR worked post-operatively. Rates of RTW were highest amongst those in managerial and professional or technical roles, whichever operation they received. RTW was poorest amongst those in elementary occupations. In associate professional/technical occupations, RTW rates were better amongst UKR recipients. Amongst participants who returned to work, 17 reported KRJL (8.5% UKR and 16.7% TKR). Respondents were more likely to have KRJL if their job involved carrying/lifting ≥10 kg (HR:4.81, 95%CI 1.55-14.93) or climbing >30 flights of stairs (HR:4.03, 95%CI 1.36-11.98). CONCLUSIONS: Knee arthroplasty recipients working pre-operatively mostly RTW. RTW may be more difficult after TKR than UKR. Jobs which involve lifting and climbing stairs may be particularly challenging. Surgeons offering knee arthroplasty should counsel patients about workability as well as risk of revision.

Risk of revision arthroplasty surgery after exposure to physically demanding occupational or leisure activities: A systematic review.

INTRODUCTION: Lower limb arthroplasty is successful at relieving symptoms associated with joint failure. However, physically-demanding activities can cause primary osteoarthritis and accordingly such exposure post-operatively might increase the risk of prosthetic failure. Therefore, we systematically reviewed the literature to investigate whether there was any evidence of increased risk of revision arthroplasty after exposure to intensive, physically-demanding activities at work or during leisure-time. METHODS: We searched Medline, Embase and Scopus databases (1985-July 2021) for original studies including primary lower limb arthroplasty recipients that gathered information on physically-demanding occupational and/or leisure activities and rates of revision arthroplasty. Methodological assessment was performed independently by two assessors using SIGN, AQUILA and STROBE. The protocol was registered in PROSPERO [CRD42017067728]. RESULTS: Thirteen eligible studies were identified: 9 (4,432 participants) after hip arthroplasty and 4 (7,137participants) after knee arthroplasty. Narrative synthesis was performed due to considerable heterogeneity in quantifying exposures. We found limited evidence that post-operative activities (work or leisure) did not increase the risk of knee revision and could even be protective. We found insufficient high-quality evidence to indicate that exposure to physically-demanding occupations increased the risk of hip revision although "heavy work", agricultural work and, in women, health services work, may be implicated. We found conflicting evidence about risk of revision hip arthroplasty associated with either leisure-time or total physical activities (occupational or leisure-time). CONCLUSION: There is currently a limited evidence base to address this important question. There is weak evidence that the risk of revision hip arthroplasty may be increased by exposure to physically-demanding occupational activities but insufficient evidence about the impact on knee revision and about exposure to leisure-time activities after both procedures. More evidence is urgently needed to advise lower limb arthroplasty recipients, particularly people expecting to return to jobs in some sectors (e.g., construction, agriculture, military).

Impact of Menopausal Symptoms on Work: Findings from Women in the Health and Employment after Fifty (HEAF) Study.

Women make up a growing proportion of the workforce and therefore many women experience menopause while in paid employment. We explored the prevalence of menopausal symptoms, the relationship between symptoms and coping with work and the risk factors associated with struggling at work during the menopause. The Health and Employment After Fifty (HEAF) community-based cohort of people aged 50-64 years was incepted 2013-2014 to study health and work. In 2019, female participants were asked to complete a questionnaire about their menopausal symptoms, and effect of those symptoms on their ability to cope at work. 409 women were eligible for inclusion. The commonest symptoms were vasomotor (91.7%); trouble sleeping (68.2%); psychological (63.6%) and urinary (49.1%). The prevalence of reporting symptoms was similar no matter which type of occupation women were performing at the time. Around one-third of women reported moderate/severe difficulties coping at work because of menopausal symptoms. Risk factors for difficulties coping at work included: financial deprivation, poorer self-rated health, depression, and adverse psychosocial occupational factors but not physical demands. More awareness is needed amongst employers in all sectors but women with financial difficulties and those with jobs in which they feel insecure, unappreciated, or dissatisfied are at greatest risk.

[Incidence of non-work-related sickness absence in Spain by economic activity of the company]. / Incidencia de la incapacidad temporal por contingencia común en España según la actividad económica de la empresa.

INTRODUCTION: The management of sickness absence due to non-work-related diseases in Spain has typically focused on the control of its duration. The goal of this study was to provide estimates for the incidence of sickness absence due to nonwork-related diseases by economic activity to help shift the focus of management of sickness absence towards prevention. METHODS: Retrospective study based on 646,337 workers and 133,812 episodes of sickness absence started in 2009, from the Working Continuous Life Sample. Incidence rate and its 95% confidence interval (CI) were calculated using Poisson regression models, crude and adjusted for age, company size, and occupational category, separately for men and women. RESULTS: The overall incidence rate was 29.8 per 100 person-years; 24.7 (95%CI: 24.5-24.9) in men and 36.3 (36.0- 36.5) in women. By economic activity, the highest crude incidence rates in men were found in "Water supply, sanitation and wastes" (35.4) and "Health activities" (33.9); for women, "Health activities" (48.3), "Public administration" (41.2) and "Transportation and storage" (41.0) were the highest sectors. CONCLUSIONS: Companies can compare their sickness absence incidence rates to these benchmark values to determine if they are within the expected reference range, which may guide management decisions more towards the prevention of sickness absence.

OBJETIVO: La gestión de la incapacidad temporal por contingencias comunes (ITcc) en España se centra más en el control de su duración que en prevenir su incidencia. El objetivo de este trabajo es proporcionar valores de la incidencia de ITcc por ramas de actividad económica para orientar su gestión hacia la prevención. MÉTODOS: Estudio retrospectivo basado en 646.337 afiliados al régimen general incluidos en la Muestra Continua de Vidas Laborales de 2009, que notifican 133.812 primeros episodios de ITcc iniciados en 2009. La tasa de incidencia, y su IC95%, se calculó con modelos de regresión de Poisson, cruda y ajustada por edad, tamaño de la empresa y categoría ocupacional, separadamente para hombres y mujeres. RESULTADOS: La tasa de incidencia total por 100 personas-años fue de 29,8 (hombres: 24,7; IC95%:24,5-24,9 y mujeres: 36,3; IC95%: 36,0-36,5). Según ramas de actividad económica, las tasas de incidencia crudas más elevadas en los hombres fueron "Suministro de agua, saneamiento y residuos" (35,4) y "Actividades sanitarias" (33,9), y en las mujeres en "Actividades sanitarias" (48,3), "Administración pública" (41,2) y "Transporte y almacenamiento" (41,0). CONCLUSIONES: Las empresas podrán comparar su incidencia de ITcc con estos valores de referencia para determinar si su incidencia está dentro del rango de valores esperados, lo que puede ayudarles a tomar decisiones orientadas a la prevención de las bajas por enfermedad común.

Cohort profile: the Spanish WORKing life Social Security (WORKss) cohort study.

PURPOSE: The global economy is changing the labour market and social protection systems in Europe. The effect of both changes on health needs to be monitored in view of an ageing population and the resulting increase in prevalence of chronic health conditions. The Spanish WORKing life Social Security (WORKss) cohort study provides unique longitudinal data to study the impact of labour trajectories and employment conditions on health, in terms of sickness absence, permanent disability and death. PARTICIPANTS: The WORKss cohort originated from the Continuous Working Life Sample (CWLS) generated by the General Directorate for the Organization of the Social Security in Spain. The CWLS contains a 4% representative sample of all individuals in contact with the Social Security system. The WORKss cohort exclusively includes individuals with a labour trajectory from 1981 or later. In 2004, the cohort was initiated with 1,022 ,79 Social Security members: 840,770 (82.2%) contributors and 182,009 (17.8%) beneficiaries aged 16 and older. FINDINGS TO DATE: The WORKss cohort includes demographic characteristics, chronological data about employment history, retirement, permanent disability and death. These data make possible the measurement of incidence of permanent disability, the number of potential years of working life lost, and the number of contracts and inactive periods with the Social Security system. The WORKss cohort was linked to temporary sickness absence registries to study medical diagnoses that lead to permanent disability and consequently to an earlier exit from the labour market in unhealthy conditions. FUTURE PLANS: Thanks to its administrative source, the WORKss cohort study will continue follow-up in the coming years, keeping the representativeness of the Spanish population affiliated to the Social Security system. The linkage between the WORKss cohort and temporary sickness absence registries is envisioned to continue. Future plans include the linkage of the cohort with mortality registries.

Incidence of sickness absence by type of employment contract: one year follow-up study in Spanish salaried workers.

BACKGROUND: To examine the differences in the incidence of registered sickness absence by type of employment contract in a large representative sample of salaried workers in Spain in 2009. METHOD: A study of 653,264 salaried workers covered by the Social Security system who had 133,724 sickness absence episodes in 2009. Crude and adjusted rate ratios and their corresponding 95 % confidence intervals (CIs) were calculated with Poisson regression models. RESULTS: The incidence rate per 100 workers-year of sickness absence for temporary workers (IR = 32.2) was slightly higher than that of permanent workers (IR = 28.9). This pattern was observed in both men (RR = 1.12; 95 % CI 1.10-1.14) and women (RR 1.11; 95 % CI 1.09-1.12). However, after adjusting for age, company size, and occupational category, the differences disappeared in men (aRR = 1.01; 95 % CI 0.99-1.02) and decreased in women (aRR = 1.06; 95 % CI 1.04-1.07). CONCLUSION: Our findings provide evidence on the independence of sickness absence benefits from the type of employment contract as well as on the nonexistence of incentives for taking sickness absence in workers with a permanent employment contract. In the context of increasing market flexibility, these results show a positive functioning of the Social Security system.
