Manual therapy for tension-type headache related to quality of work life and work presenteeism

Secondary analysis of a randomized controlled trial
OBJECTIVE: The objective of this research is to evaluate the efficacy of manual therapy for tension-type headache (TTH) in restoring workers quality of work life, and how work presenteeism affects this relation. DESIGN: This study is a secondary analysis of a factorial, randomized clinical trial on manual therapy interventions. Altogether, 80 patients (85% women) with TTH and without current symptoms of any other concomitant disease participated. INTERVENTIONS: An experienced therapist delivered the treatment: myofascial inhibitory technique (IT), articulatory technique (AT), combined technique (IT and AT), and control group (no treatment). RESULTS: In general, all treatments as compared to our control group had a large effect (f>/=.69) in the improvement of participants' quality of work life. Work presenteeism interacted with TTH treatment type's efficacy on participant's quality of work life. The inhibitory technique lead to higher reports of quality of work life than other treatment options only for participants with very low frequency of work presenteeism. In turn, TTH articulatory treatment techniques resulted in higher reports of quality of work life for a high to very high work presenteeism frequency. CONCLUSION: Articulatory manipulation technique is the more efficient treatment to improve quality of work life when the frequency of work presenteeism is high. Implications for future research and practice are discussed.

Relationship Between Opioid Prescribing Patterns and Claim Duration and Cost

Objective: The aim of this study was to assess the relationship between timing and duration of opioid prescriptions, disability duration, and claims costs for work-related injuries.
Method: A retrospective cohort study using lost time compensation claimant data to examine the relationship between opioid prescription patterns and claim duration and cost. Logistic regression adjusted for sex, marital status, initial reserve, attorney involvement, and spinal surgeries.
Results: Odds ratios for claim cost at least $100,000 and duration at least 3 years were not statistically different between groups prescribed opioids less than 30 days and those not prescribed opioids. Claims with short-acting opioids continued after 180 days; the odds ratios for claim cost at least $100,000 and duration at least 3 years were 6.21 (95% confidence interval 5.30 to 7.28) and 3.32 (95% confidence interval 2.94 to 3.74).
Conclusion: Claim cost and lost time are related to when and how long opioids are prescribed for work-related injuries.

Effects of graded return-to-work

A propensity-score-matched analysis
Objectives: Graded work exposure is deemed to have a therapeutic effect. In Germany, graded return-to-work (GRTW) is therefore frequently used following a rehabilitation program if workers are still unable to perform full job duties. The aim of the analyses was to determine long-term effects on disability pension and regular employment.
Methods: Analyses were performed with longitudinal administrative data. Patients aged 18–60 years who attended an orthopedic, cardiac, oncological, or psychosomatic rehabilitation between January and June 2007 were eligible to participate in a GRTW scheme. The effects of GRTW were analyzed by a propensity-score-matched comparison of patients with and without GRTW. Outcomes were disability pension rates, regular income, and the duration of receiving welfare benefits due to sickness absence and unemployment up to the end of 2009.
Results: The propensity-score-matched sample comprised 1875 patients on GRTW and 1875 matched controls not undergoing GRTW. The probability of a disability pension was decreased by about 40% among GRTW patients [5.4% versus 8.6%; hazard rate ratio (HR) 0.62, 95% confidence interval (95% CI) 0.49–0.80]. The three-year income (2007–2009) was EUR12 920 higher (95% CI EUR10 054–15 786) in the GRTW group. The duration of receiving welfare benefits due to sickness absence and unemployment was significantly reduced.
Conclusions: Graded work exposure supports labor participation and reduces the risk of permanent work disability.

Facteurs prédictifs d'une restriction d'aptitude ou d'une inaptitude au poste de travail antérieur en visite de reprise

Élaboration d'un score
L'objectif est d'étudier les facteurs liés à la décision d'aptitude du médecin du travail lors de la visite de reprise d'un salarié après un arrêt de travail pour maladie. Une enquête descriptive multicentrique transversale a été réalisée auprès de 402 salariés suivis par des services de santé au travail (SST) de l'agglomération stéphanoise. La reprise du travail au poste antérieur est significativement liée à certains facteurs professionnels et médicaux. Un score prédictif d'un avis d'aptitude autre que " apte " a été construit en renseignant quatre variables explicatives de l'avis d'aptitude identifiées dans l'analyse multivariée. Ce score pourrait être utilisé pour identifier en amont les situations difficiles de reprise du travail, de manière à mieux anticiper la mise en place des procédures de maintien dans l'emploi.

Sickness absence and mental health

Evidence from a nationally representative longitudinal Survey
Objectives Previous studies have consistently reported evidence of large significant associations between measures of psychological health and sickness absence. Some of this association, however, may be confounded by relevant covariates that have not been controlled. By using data with repeated observations from the same individuals, this study aimed to quantify the bias due to unobserved characteristics that are time invariant.
Methods Longitudinal data from the Household, Income, and Labour Dynamics in Australia (HILDA) Survey were used to estimate negative binomial regression models of the number of annual paid sickness absence days. Observations spanning the period 2005–2012, and covering all employed persons aged 15–64 years, were used (56 348 observations from 13 622 individuals).
Results Significant associations between the number of paid sickness absence days taken each year and scores on the mental health subscale of the SF-36 (MHI-5) were found. Inclusion of correlated random effects (which effectively control for unobserved person-specific factors that do not vary over time), however, resulted in a marked decline in the magnitude of this association. For persons with severe depressive symptoms (MHI-5 ≤52), the estimated incidence rate ratios were in the range 1.13–1.14 for men and 1.10–1.12 for women.
Conclusions Poor mental health is a risk factor affecting work attendance, but the magnitude of this effect, at least in a country where the rate of sickness absence is relatively low, is modest.

Lag Times in Reporting Injuries, Receiving Medical Care, and Missing Work

Associations With the Length of Work Disability in Occupational Back Injuries
Objective: The aim of this study is to examine the associations between lag times following occupational low back injury and the length of work disability.
Methods: In a retrospective cohort study using workers' compensation claims, random effects Tobit models were used to explore how disability length relates to three lag times: the number of days from the date of injury to reporting the injury, the number of days from the date of injury to medical care, and the number of days from the date of injury to initiating work disability.
Results: In general, shorter lag times for each of the different lags were related to shorter lengths of disability.
Conclusions: Decreasing the length of the lag times in reporting injuries, receiving medical care, and missing work may help to decrease the length of work disability for workers after low back injury.

Workplace social capital and risk of long-term sickness absence

Are associations modified by occupational grade?
BACKGROUND: Workplace social capital (WSC) is an emerging topic among both work environment professionals and researchers. We examined (i) whether high WSC protected against risk of long-term sickness absence (LTSA) in a random sample of the Danish workforce during a 1-year follow-up and (ii) whether the association of WSC with sickness absence was modified by occupational grade. METHODS: We measured WSC by self-report in a cohort of 3075 employees and linked responses to a national register of sickness absence. We calculated hazard ratios (HRs) and 95% confidence intervals (CIs) of onset of LTSA (>/=21 days), adjusted for covariates. We stratified analyses by occupational grade and examined if there was an interaction effect of WSC and occupational grade. RESULTS: A one standard deviation higher WSC score predicted a reduced risk of sickness absence after adjustment for sociodemographic variables, prevalent health problems and health behaviours (HR = 0.85, 95% CI = 0.74-0.99). The HR was attenuated and lost statistical significance after further adjustment for occupational grade (HR = 0.90, 95% CI = 0.78-1.04). When stratified by occupational grade, high WSC predicted a decreased risk of sickness absence among higher grade workers (HR = 0.61, 95% CI = 0.44-0.84) but not among lower grade workers (HR = 0.98, 95% CI = 0.83-1.15). The interaction effect of WSC and occupational grade was statistically significant (HR = 0.97, 95% CI = 0.95-0.99). CONCLUSION: High WSC might reduce risk of LTSA. However, the protective effect appears to be limited to workers of higher occupational grade.

Length of Disability and Medical Costs in Low Back Pain

Do State Workers' Compensation Policies Make a Difference?
Objective: The aim of the study was to examine the impact of state workers' compensation (WC) policies regarding wage replacement and medical benefits on medical costs and length of disability (LOD) in workers with low back pain (LBP).
Methods: Retrospective cohort analysis of LBP claims from 49 states (n?=?59,360) filed between 2002 and 2008, extracted from a large WC administrative database.
Results: Longer retroactive periods and state WC laws allowing treating provider choice were associated with higher medical costs and longer LOD. Limiting the option to change providers and having a fee schedule were associated with longer LOD, except that allowing a one-time treating provider change was associated with lower medical costs and shorter LOD.
Conclusions: WC policies about wage replacement and medical treatment appear to be associated with WC LBP outcomes, and might represent opportunities to improve LOD and reduce medical costs in occupational LBP.

Is Early Prescribing of Opioid and Psychotropic Medications Associated With Delayed Return to Work and Increased Final Workers’ Compensation Cost?

Objective: To explore the association between the initial 60 days of prescriptions for psychotropic medications and final workers' compensation claim outcomes.
Methods: A cohort of 11,394 claimants involved in lost time injuries between 1999 and 2002 were followed through December 31, 2009. Logistic regressions and Cox Proportional Hazard Models were used in the analysis.
Results: The initial 60 days of prescriptions for psychotropic medications were significantly associated with a final claim cost at least $100,000. Odds ratios were 1.88 for short-acting opioids, 2.14 for hypnotics, antianxiety agents, or antidepressants, and 3.91 for long-acting opioids, respectively. Significant associations were also found between decreased time lost from work and decreased claim closures during the study period.
Conclusions: Early prescription of opioids and other psychotropic drugs may be useful predictors of high claim costs and time lost from work.

Work participation and health-related characteristics of sickness absence beneficiaries with multiple somatic symptoms

Objectives: The primary aim was to study whether high levels of multiple symptoms influenced sick-listed individuals' employment status or desire to return to work (RTW) and whether this was associated with social relations at work.
Study design: A cross-sectional study nested in a clinical trial.
Methods: In 2011–2012, 736 (34%) of 2172 sick-listed individuals completed a posted questionnaire and were included. Main outcome was self-reported employment status. The Symptom Check List (SCL-SOM)'s sum score (0–48) was categorized in high (>18) and low (≤18) levels. Previous employment, sick-listing, and use of health care were register-data. Multivariate logistic regression analyses with adjustments were performed.
Results: Beneficiarie with high SCL-SOM score (n = 218, 33%) reported poorer health, job satisfaction, a lower desire to RTW and more problems with supervisors. The risk of being unemployed was higher for this group than for those with a low score. Adjusting for general health reduced the association between symptoms and unemployment, whereas problems with social relations only affected it marginally.
Conclusions: Sick-listed individuals reporting high levels of symptoms were more often unemployed and less frequently desired to RTW than those with few symptoms. The association could not be explained by problems with social relations at work.

Programme de prise de décision entre l'ergothérapeute et le travailleur ayant une incapacité due à un trouble musculosquelettique persistant

Les travailleurs et les autres acteurs qui prennent des décisions en matière d'interventions de retour au travail ont souvent des intérêts et des buts différents. Le processus de prise de décision partagée (PDP) est une approche centrée sur la personne qui permet d'agir sur les écarts entre les travailleurs et les autres acteurs par rapport au but et au plan d'action à mettre de l'avant. À notre connaissance, un programme de PDP n'avait jamais été spécifiquement contextualisé en réadaptation au travail.

Chronic low back pain among French healthcare workers and prognostic factors of return to work (RTW)

A non-randomized controlled trial
Background: Many factors influence the return to work of workers with chronic low back pain (CLBP). They have been said to vary according to socio-professional group. This study first aimed to compare prognostic factors influencing the return to work of CLBP healthcare workers (HCWs) and other workers (non-HCWs) after rehabilitation coupled with an occupational intervention. The second objective was to improve the evolution of indicators such as clinical examination, psychosocial impact and pain impact.
Methods: Between 2007 and 2012, a cohort of 217 CLBP workers (54.8 %-women; mean age = 41.3 ± 9.5 years, 118 non-HCWs; 99 HCWs mainly from the public sector) was included in an ambulatory rehabilitation program (standard physiotherapy or intensive network physiotherapy) coupled with an occupational intervention. Workers completed a questionnaire and had a clinical examination at baseline and after 24 months' follow up. Physical, social and occupational data was collected at the same time. Statistical analyses were performed to evaluate prognostic factors for return to work and compare the two worker populations.
Results: There was no difference between groups for the rate of OP (occupational physician) intervention or type of physiotherapy. 77.3 % of workers returned to work after 2 years following inclusion. To be an HCW (OR 0.1; 95 % CI [0.03–0.34]), to have less than 112 sick- leave days (OR 1.00; 95 % CI [0.93–1.00]), a small fingertip-floor distance (OR 0.96; 95 % CI [0.93–0.99]), a low anxiety/depression score (OR 0.97; 95 % CI [0.95–1.00]), a low impact of CLBP on daily life (OR 0.96; 95 % CI [0.93–1.00]), and on quality of life (OR 0.98; 95 % CI [0.95–1.00]) at baseline were statistically associated with return to work after 2 years of follow up. Only the profession (workplace) was statistically associated with return to work after 2 years of follow up using multivariate analysis.
Conclusion: To our knowledge, this is the first cohort study concerning predictive factors of RTW among CLBP workers after 2 years of follow up. Interventions in the work environment did not seem to predict job retention significantly. But only 50 % of the employees in both groups (HCW and non-HCW) had one intervention at their workplace after 2 years. This study underlined the fact that the type of physiotherapy with a well-trained physiotherapist used to take care of CLBP could not impact on the RTW forecast. To develop these initial results, it might be interesting to study the comparison between private and public sectors and to randomize the physiotherapeutic intervention.

The capability set for work

Development and validation of a new questionnaire
Objectives: The aim of this study was to develop a questionnaire to measure work capabilities based on Amartya Sen's capability approach and evaluate its validity.
Methods: The development of the questionnaire was based on a combination of qualitative and quantitative methods: interviews, literature study, and an expert meeting. Additionally, in a survey, the validity was evaluated by means of hypotheses testing (using correlations and regression analyses).
Results: The questionnaire consists of a set of seven capability aspects for work. For each aspect, it is determined whether it is part of a worker's capability set, ie, when the aspect is considered valuable, is enabled in work, and is realized. The capability set was significantly correlated with work role functioning-flexibility demands (-0,187), work ability (-0.304), work performance (-0.282), worked hours (-0.073), sickness absence (yes/no) (0.098), and sickness absence days (0.105). The capability set and the overall capability item are significantly associated with all work outcomes (P<0.010).
Conclusions: The new capability set for work questionnaire appears to be a valid instrument to measure work capabilities. The questionnaire is unique because the items include the valued aspects of work and incorporate whether a worker is able to achieve what (s)he values in his/her work. The questionnaire can be used to evaluate the capability set of workers in organizations to identify aspects that need to be addressed in interventions.
