Prevalence of occupational moral injury and post-traumatic embitterment disorder: a systematic review and meta-analysis.

OBJECTIVES: Occupational moral injury and post-traumatic embitterment disorder (PTED) describe the psychological distress caused by exposure to injustice at work. This meta-analysis aims to determine the prevalence of occupational moral injury and PTED and establish whether prevalence estimates differ depending on occupation. DESIGN: A systematic review and meta-analysis. DATA SOURCES: Google Scholar, PubMed, APA PsycINFO, Web of Science Core Collection, Scopus, ScienceDirect and Sage Journals Online were searched in June 2020 and updated in November 2022. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Observational studies that measured prevalence or average scores of moral injury, or PTED in any occupational group and any geographical location. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers screened and coded eligible studies. Study design, participant demographics, sampling method, location, measurement tool and prevalence or average scores were extracted. Risk of bias was assessed using the Quality Assessment Checklist for Prevalence Studies tool. Meta-analysis was conducted using random effects models. Results that could not be combined were summarised qualitatively in a narrative synthesis using the Guidance for Systematic Reviews. RESULTS: In total, 88 studies across armed forces and veterans, healthcare, first responders, educators, journalists, child protection service employees, the unemployed, public-sector employees and mixed occupations were included. Studies included in each separate meta-analysis based on the measure used ranged from 2 to 30. The pooled prevalence of clinically relevant moral injury in healthcare professionals was 45%, and exposure to any potentially morally injurious event (PMIE) across occupations was 67%. Exposure to transgressions by others and betrayal was significantly lower in the armed forces than civilian occupations. Pooled prevalence of PTED across occupations was 26%. CONCLUSION: Exposure to PMIEs, moral injury symptoms and PTED are prevalent at work and exposure to transgressions by others and betrayal are more likely in civilian occupations than the armed forces.

Increased Mortality Associated With Disability Among Workers' Compensation Claimants With Upper Extremity Neuropathy.

OBJECTIVE: The aim of the study was to evaluate and compare mortality after disabling and nondisabling occupational injuries. METHODS: Vital status was ascertained through 2020 for 2077 individuals with a workers' compensation claim for upper extremity neuropathy in West Virginia in 1998 or 1999. Standardized mortality ratios compared mortality to the West Virginia general population. Hazard ratios (HRs) obtained from Cox regression models compared mortality among those with and without lost work time or permanent disability. RESULTS: Overall, the standardized mortality ratio for accidental poisoning deaths was elevated (1.75, 95% confidence interval [CI]: 1.08-2.68). All-cause mortality HRs and cancer HRs were elevated for lost work time (HR = 1.09, 95% CI: 0.93-1.28; HR = 1.50, 95% CI: 1.09-2.08, respectively) and permanent disability (HR = 1.22, 95% CI: 1.04-1.44; HR = 1.78, 95% CI: 1.27-2.48, respectively). CONCLUSIONS: Work-related disability was associated with broad elevations in mortality.

Community acquired pressure injuries in a work-related spinal cord injury population: Problem characterization and assessment of a working solution.

BACKGROUND: To characterize the problem of community-acquired pressure injuries (CAPIs) in a work-related spinal cord injury (SCI) population in Canada and assess the benefits of a person-centered solution. Characterization of the problem and a solution, albeit in an insured Worker's Compensation Board of British Columbia (WorkSafeBC) cohort, may inform the supply of solutions in the larger SCI population with disparate access to healthcare. METHODS: For this observational study, data on 244 WorkSafeBC clients, who received an intervention featuring pressure injury (PI) assessment between 2011 and 2015, were used to characterize the problem. Data on observed injuries, risk, referrals, and outcomes were linked to healthcare service claims. Employing an activity-based costing methodology, total expenditures on attributed services were calculated for clients with 1 or more PIs. Intervention cost and benefits from the insurer's perspective are considered. RESULTS: 84 of 244 clients had 1 or more PIs at assessment, with attributed mean cost of $56,092 in 2015 Canadian dollars (CAD). Mean cost by PI severity range from $9580 to $238,736. At an intervention cost of $820,618, detection of less severe injuries provided an opportunity to prevent progression and achieve $3 million in cost avoidance. Follow-up data suggest reasonable returns. Reductions in the incidence, number, and risk of pressure injuries were also observed. CONCLUSIONS: The analysis establishes the cost of CAPIs in a Canadian-based work-related SCI population and suggests preventative and early intervention is not only feasible but also practical. Results are relevant to decisions regarding the use of proactive prevention-based treatment models as opposed to reactive, solutions in the larger SCI population.

Increased overall and cause-specific mortality associated with disability among workers' compensation claimants with low back injuries.

BACKGROUND: Mortality tends to be higher among people who do not work than among workers, but the impact of work-related disability on mortality has not been well studied. METHODS: The vital status through 2015 was ascertained for 14 219 workers with an accepted workers' compensation claim in West Virginia for a low back injury in 1998 or 1999. Mortality among the cohort compared with the West Virginia general population was assessed using standard life table techniques. Associations of mortality and disability-related factors within the cohort were evaluated using Cox proportional hazards regression. RESULTS: Compared to the general population, mortality from accidental poisoning was significantly elevated among the overall cohort and lost-time claimants. Most deaths from accidental poisoning in the cohort were due to drug overdoses involving opioids. Mortality from intentional self-harm was also significantly elevated among lost-time claimants. In internal analyses, overall mortality and mortality from cancer, heart disease, intentional self-harm, and drug overdoses involving opioids was significantly associated with lost time. Overall mortality and mortality from drug overdoses involving opioids were also significantly associated with amount of lost time, permanent partial disability, and percent permanent disability. Heart disease mortality was also significantly associated with the amount of lost time. CONCLUSIONS: The results suggest that disability itself may impact mortality risks. If confirmed, these results reinforce the importance of return to work and other efforts to reduce disability.

Relationship between early prescription dispensing patterns and work disability in a cohort of low back pain workers' compensation claimants: a historical cohort study.

OBJECTIVES: To examine and compare whether dispensing of prescription opioids, non-steroidal anti-inflammatory drugs (NSAIDs) and skeletal muscle relaxants (SMRs) within 8 weeks after a work-related low back pain (LBP) injury is associated with work disability. METHODS: A historical cohort study of 55 571 workers' compensation claimants with LBP claims in British Columbia from 1998 to 2009 was conducted using linked compensation, dispensing and healthcare data. Four exposures were constructed to estimate the effect on receipt of benefits and days on benefits 1 year after injury: drug class(es) dispensed, days' supply, strength of opioids dispensed and average daily morphine-equivalent dose. RESULTS: Compared with claimants receiving NSAIDs and/or SMRs, the incidence rate ratio (IRR) of days on benefits was 1.09 (95% CI 1.04 to 1.14) for claimants dispensed opioids only and 1.26 (95% CI 1.22 to 1.30) for claimants dispensed opioids with NSAIDs and/or SMRs. Compared with weak opioids only, the IRR for claimants dispensed strong opioids only or strong and weak opioids combined was 1.21 (95% CI 1.12 to 1.30) and 1.29 (95% CI 1.20 to 1.39), respectively. The incident rate of days on benefits associated with each 7-day increase in days supplied of opioids, NSAIDs and SMRs was 10%, 4% and 3%, respectively. Similar results were seen for receipt of benefits, though effect sizes were larger. CONCLUSIONS: Findings suggest provision of early opioids leads to prolonged work disability compared with NSAIDs and SMRs, though longer supplies of all drug classes are also associated with work disability. Residual confounding likely partially explains the findings. Research is needed that accounts for prescriber, system and workplace factors.

Model of Human Occupation as a framework for implementation of Motivational Interviewing in occupational rehabilitation.

BACKGROUND: A conceptual framework is needed to understand injured workers' decision-making and inform evidence-based interventions to address behavior change regarding return-to-work (RTW). The Model of Human Occupation (MOHO) can help with understanding how an injured worker's characteristics can generate behavior change while Motivational Interviewing (MI) can help facilitate behavior change. OBJECTIVE: This theoretical paper provides an overview of how MOHO and MI can be applied and integrated in occupational rehabilitation. The objectives of this paper are to: (1) evaluate MOHO as a framework for supporting occupational therapists (OTs) in occupational rehabilitation; (2) describe MI as a suitable approach for OTs in occupational rehabilitation; and (3) compare and integrate MOHO and MI. METHOD: Several important works and reviews were used to integrate MOHO and MI with occupational rehabilitation. IMPLICATIONS FOR PRACTICE: The identification of a model and approach to support OT practice in occupational rehabilitation can assist OTs to determine the most appropriate interventions and contribute to standards of best practice. CONCLUSIONS: Integrating MOHO and MI provides a comprehensive framework for understanding impairment and RTW change processes with the potential to reduce work disability and improve RTW outcomes.

Insurers' perspective on barriers and facilitators for return to work after occupational injuries.

BACKGROUND: Despite the importance of the legislative and insurance systems in the return to work process after an occupational injury, the perspective of the insurer on what influences return to work has rarely been documented. OBJECTIVE: To understand the barriers or facilitators for return to work, from the perspective of the insurer. METHODS: A comprehensive qualitative approach was used. Semi-directed interviews were done with nineteen (19) insurers (claims adjudicator and rehabilitation case manager) from a Canadian workers' compensation board. A thematic analysis was done using QDA Minor Software. RESULTS: Fourteen themes (e.g. family reaction, quality of work relationship) were classified into four categories representing the main stakeholders: worker with disability, workplace, healthcare system and compensation system. Emotional, cognitive, and adaptive reactions from the worker and his family were identified. We observed that good work relations and support practices, lack of access to medical resources, focus on the employee's ability, and complexity and consequences of the compensation process are the main barriers and facilitators from the insurers' perspective. Many of the perceived elements are coherent with the compensation system's administrative and legal context. CONCLUSIONS: The results enable us to better understand the insurers' perspective regarding what influences return to work. It reinforces the necessity to consider the administrative and legal context to better understand the insurers' perspective.

Comparative Analysis of Impairment Ratings From the 5th to 6th Editions of the AMA Guides.

OBJECTIVE: The association of American Medical Association's (AMA) Guides edition with impairment ratings is uncertain. METHODS: We used data from a consecutive sample of 249 injured workers referred for an independent evaluation 10 months before and after assessors switched from the 5th to the 6th edition of the AMA Guides. RESULTS: The median whole person impairment rating was 7.0% (interquartile range [IQR]: 4 to 14) for 131 claimants assessed with the 5th edition of the Guides, and 4.0% (IQR: 2 to 8) for 118 claimants assessed with the 6th edition (P-value for difference: 0.002). Multivariable analysis showed a 36.4% relative reduction (95% confidence interval [CI] 17.2% to 57.3%) in impairment rating with the 6th edition of the Guides versus the 5th edition. CONCLUSIONS: The 6th edition of the AMA Guides provides systematically lower impairment ratings for injured workers than the 5th edition.

Lag times in the work disability process: Differences across diagnoses in the length of disability following work-related injury.

BACKGROUND: The amount of time between key points in the work disability and workers' compensation process, referred to as lag times, has been shown to relate to work disability outcomes but little research has examined how this finding may differ based on the diagnosis associated with the cause of work disability. OBJECTIVE: To examine whether relationships between lag times in the work disability process and disability duration vary by diagnosis in a sample of workers' compensation claims. METHODS: Using workers' compensation claims, Analysis of Covariance was used to estimate differences in disability duration across three lag times (days from the date of injury to: reporting the injury, seeking medical care, and starting lost work time paid by the workers' compensation insurer) and injury diagnosis groups (Work-related Musculoskeletal Disorders (WRMSD) and fractures). RESULTS: WRMSD tended to have longer lag times than fractures, whereas disability duration tended to be longer for fractures than WRMSD. Overall, shorter lag times were associated with shorter disability duration, but the relationships varied across diagnosis groups, and greater variation in disability duration was observed for WRMSD compared to fractures. CONCLUSIONS: The findings suggest the importance of responding to work-related injuries by reporting the injury, receiving medical care, and taking time off of work if necessary, in a timely fashion.

The preventable burden of work-related ill-health.

Background: The fraction of ill-health overall attributable to occupational conditions has not been extensively evaluated, thus contributing to the perception of a lesser relevance of education and research in occupational health in respect to other fields of medical research and practice. Aims: To assess the relevance of work-related conditions on the aetiology of human ill-health in different health domains. Methods: We extracted the risk estimates associated with heritability and with occupational risk factors for chronic lymphocytic leukaemia (CLL), major depressive disorder (MDD) and long QT syndrome (LQTS) from 13 published international reports. The selection criteria for the eligible studies were: genome-wide studies, or studies of the occupational risk factors associated with one of the three diseases of interest. We calculated and compared the respective population attributable fraction for the combined occupational risk factors, and for heritability. Results: We estimated that occupational risk factors would account for 12% (95% confidence interval (CI) 4-19) of CLL, 11% (95% CI 7-15) of MDD and 10% (95% CI 2-13) of LQTS burden in the general population. The corresponding figures for heritability would be 16% (95% CI 11-22), 28% (95% CI 20-5) and 17% (95% CI 7-27). Conclusions: More efforts in capacity building and research in occupational health are warranted aiming to prevent ill-health and to preserve a productive life for the ageing work population.

Prescription Dispensing Patterns Before and After a Workers' Compensation Claim: An Historical Cohort Study of Workers With Low Back Pain Injuries in British Columbia.

OBJECTIVE: Compare prescription dispensing before and after a work-related low back injury. METHODS: Descriptive analyses were used to describe opioid, nonsteroidal anti-inflammatory drug (NSAID), and skeletal muscle relaxant (SMR) dispensing 1 year pre- and post-injury among 97,124 workers in British Columbia with new workers' compensation low back claims from 1998 to 2009. RESULTS: Before injury, 19.7%, 21.2%, and 6.3% were dispensed opioids, NSAIDs, and SMRs, respectively, increasing to 39.0%, 50.2%, and 28.4% after. Median time to first post-injury prescription was less than a week. Dispensing was stable pre-injury, followed by a sharp increase within 8 weeks post-injury. Dispensing dropped thereafter, but remained elevated nearly a year post-injury, an increase attributable to less than 2% of claimants. CONCLUSION: These drug classes are commonly dispensed, particularly shortly after injury and dispensing is of short duration for most, though a small subgroup receives prolonged courses.

Early-Claim Modifiable Factors Associated With Return-to-Work Self-Efficacy Among Workers Injured at Work: Are There Differences Between Psychological and Musculoskeletal Injuries?

OBJECTIVE: The objective of this study was to investigate modifiable early-injury factors which are associated with self-efficacy to return-to-work (RTW-SE) and explore whether these factors are different for people with psychological or upper-body musculoskeletal (UB-MSK) injuries. METHODS: The study used a sample of workers with a UB-MSK (N = 244) or psychological (N = 113) injury who were off work. Differences between injury types were investigated across variables related to: (1) communication with RTW stakeholders; and (2) components of the job itself. A stratified and multigroup analysis was conducted using structural equation modeling (SEM). RESULTS: Injury-stratified models revealed no significant differences. In a combined model, higher job autonomy and low-stress contact from the RTW coordinator remained significantly associated with higher RTW-SE. CONCLUSIONS: Job autonomy and low-stress contact from the RTW coordinator are possible areas to target to increase self-efficacy among injured workers.

Work Enabling Opioid Management.

OBJECTIVE: This study describes the relationship between opioid prescribing and ability to work. METHODS: The opioid prescription patterns of 4994 claimants were studied. Three groups were constructed: 1) at least 3 consecutive months prescribed (chronic opioid therapy; COT); 2) less than 3 consecutive months prescribed (acute opioid therapy; AOT); and 3) no opioids prescribed. Variables included sex, age, daily morphine equivalent dose (MED), days opioids were prescribed, temporary total days (TTDs), and medical/indemnity/total costs. RESULTS: The COT versus AOT claimants had higher opioid costs ($8618 vs $94), longer TTD (636.2 vs 182.3), and average MED (66.8 vs 34.9). Only 2% of the COT cohort were not released to work. Fifty-seven percent of patients in the COT category (64 of 112) were released to work while still receiving opioids. CONCLUSION: COT does not preclude ability to work when prescribing within established guidelines.

Laboratory Animal Bite Anaphylaxis: A National Survey: Part 2: Treatment Protocols.

OBJECTIVE: This study documents current treatment protocols for laboratory animal bite anaphylaxis in the United States. METHODS: An online survey was e-mailed to designated institutional officials at laboratory animal facilities identified by the National Institutes of Health Office of Laboratory Animal Welfare. RESULTS: One hundred eighty-nine organizations responded to the question of whether they had a treatment protocol with 32% indicating that they had a protocol. Having a case of anaphylaxis increased the likelihood of having a protocol (61%). Of those with a protocol, 58% included treatment with injectable epinephrine, if clinically indicated. Among all respondents, only 14% reported keeping injectable epinephrine at the location where animal work is performed. CONCLUSIONS: A minority of responding organizations had protocols in place to address laboratory animal bite anaphylaxis. Organizations with workers at risk should consider implementing a protocol for assessment and treatment.

Systematic review: effect of psychiatric symptoms on return to work after occupational injury.

BACKGROUND: Although post-traumatic stress disorder (PTSD) and depression are commonly observed following injury, few studies have focused on the effect of psychiatric symptoms on return to work (RTW) following occupational injury. AIMS: To determine the impact of psychiatric symptoms on RTW after occupational injury. METHODS: PubMed (1980-2014), MEDLINE (1980-2014) and PsycINFO (1980-2014) databases were examined with linked fields of research in February 2015. Reference lists of eligible articles were also searched. Cohort, case-control, cross-sectional studies and intervention studies were selected according to predefined criteria. Evidence was synthesized qualitatively according to the Downs and Black and Crombie checklist. The standard checklist was used to assess the methodological quality of each study by two reviewers. RESULTS: Five of the 56 records met the inclusion and exclusion criteria. After occupational injury, the rates of RTW after the injuries varied widely, ranging from 31 to 63%. PTSD symptoms and depressive symptoms appeared to be negatively associated with RTW. CONCLUSIONS: Currently, the evidence is insufficient to draw conclusions about the effects of psychiatric symptoms on RTW after occupational injury and more studies are needed. Future studies with large sample sizes are warranted to determine the prevalence of RTW and to detect the psychiatric factors.

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.

Marginal structural modelling of associations of occupational injuries with voluntary and involuntary job loss among nursing home workers.

OBJECTIVES: Qualitative studies have highlighted the possibility of job loss following occupational injuries for some workers, but prospective investigations are scant. We used a sample of nursing home workers from the Work, Family and Health Network to prospectively investigate association between occupational injuries and job loss. METHODS: We merged data on 1331 workers assessed 4 times over an 18-month period with administrative data that include job loss from employers and publicly available data on their workplaces. Workers self-reported occupational injuries in surveys. Multivariable logistic regression models estimated risk ratios for the impact of occupational injuries on overall job loss, whereas multinomial models were used to estimate OR of voluntary and involuntary job loss. Use of marginal structural models allowed for adjustments of multilevel lists of confounders that may be time varying and/or on the causal pathway. RESULTS: By 12 months, 30.3% of workers experienced occupational injury, whereas 24.2% experienced job loss by 18 months. Comparing workers who reported occupational injuries to those reporting no injuries, risk ratio of overall job loss within the subsequent 6 months was 1.31 (95% CI 0.93 to 1.86). Comparing the same groups, injured workers had higher odds of experiencing involuntary job loss (OR 2.19; 95% CI 1.27 to 3.77). Also, compared with uninjured workers, those injured more than once had higher odds of voluntary job loss (OR 1.95; 95% CI 1.03 to 3.67), while those injured once had higher odds of involuntary job loss (OR 2.19; 95% CI 1.18 to 4.05). CONCLUSIONS: Despite regulatory protections, occupational injuries were associated with increased risk of voluntary and involuntary job loss for nursing home workers.

The Added Value of Collecting Information on Pain Experience When Predicting Time on Benefits for Injured Workers with Back Pain.

Objectives Some injured workers with work-related, compensated back pain experience a troubling course in return to work. A prediction tool was developed in an earlier study, using administrative data only. This study explored the added value of worker reported data in identifying those workers with back pain at higher risk of being on benefits for a longer period of time. Methods This was a cohort study of workers with compensated back pain in 2005 in Ontario. Workplace Safety and Insurance Board (WSIB) data was used. As well, we examined the added value of patient-reported prognostic factors obtained from a prospective cohort study. Improvement of model fit was determined by comparing area under the curve (AUC) statistics. The outcome measure was time on benefits during a first workers' compensation claim for back pain. Follow-up was 2 years. Results Among 1442 workers with WSIB data still on full benefits at 4 weeks, 113 were also part of the prospective cohort study. Model fit of an established rule in the smaller dataset of 113 workers was comparable to the fit previously established in the larger dataset. Adding worker rating of pain at baseline improved the rule substantially (AUC = 0.80, 95 % CI 0.68, 0.91 compared to benefit status at 180 days, AUC = 0.88, 95 % CI 0.74, 1.00 compared to benefits status at 360 days). Conclusion Although data routinely collected by workers' compensation boards show some ability to predict prolonged time on benefits, adding information on experienced pain reported by the worker improves the predictive ability of the model from 'fairly good' to 'good'. In this study, a combination of prognostic factors, reported by multiple stakeholders, including the worker, could identify those at high risk of extended duration on disability benefits and in potentially in need of additional support at the individual level.

If you've seen one construction worksite stretch and flex program you've seen one construction worksite stretch and flex program.

BACKGROUND: Work-related Musculoskeletal Disorders (WMSD) account for approximately one-third of all injuries in the U.S. construction industry. Many companies have implemented stretch and flex (s/f) programs to reduce WMSD despite a lack of evidence showing effectiveness. METHODS: We conducted a mixed-methods study to understand (a) why employers continue devoting resources to s/f programs; (b) how programs vary; and (c) any actual or perceived benefits. RESULTS: Nineteen safety and health professionals were interviewed and 133 more (13.3% response rate) completed an on-line survey. Fifty-six percent had implemented an s/f program with the primary goal of reducing WMSDs; though most did not review data to determine goal achievement. Program structure varied in terms of duration, frequency, and type of stretches. There was strong agreement about mandating attendance but not participation, due primarily to liability issues. Cost was a factor when deciding to implement a program but not for sustaining one. The majority had not implemented other ergonomic prevention activities, but many had started conducting daily safety huddles for task and safety planning. Those reporting a reduction in WMSDs agreed that it was not due to the s/f program alone and that other benefits included increased worker camaraderie, communication, and collaboration. CONCLUSION: Although there is little to no scientific evidence showing that they work as intended, construction companies continue to implement s/f programs with the goal of reducing WMSDs. Bringing work crews together for s/f activities has prompted employers to also begin conducting daily safety huddles. Although employers may not be able to link reduced WMDS to an s/f program, the ancillary benefits may warrant the time and resources. PRACTICAL APPLICATIONS: S/f programs should be only one component of a more comprehensive ergonomics prevention program. Conducting daily safety huddles at the same time also may enhance worker communication, camaraderie, collaboration and improve safety outcomes.
