Incidence, trends and factors associated with psychological injury among health and social care workers in New South Wales, Australia: a retrospective cohort study of workers' compensation claims.

OBJECTIVES: To describe and compare the incidence and trends of workers' compensation (WC) claims for psychological injury: (1) between health and social care (HSC) industry and other industries; (2) among specific occupations in the HSC industry; and (3) to determine if psychological injury claim rates differ by age and gender in the HSC industry and among specific occupations. METHODS: A retrospective cohort study was conducted using data from the New South Wales WC system. Workers with accepted psychological injury claims between July 2012 and June 2021 were included. Negative binomial regression models were employed to estimate incidence rate ratios and 95% CIs. RESULTS: The HSC industry had a higher incidence (2.4 per 1000 workers) than all other industries combined (1.1 per 1000 workers). In the HSC industry, the incidence increased from 1.8 in 2013-2015 to 3.4 in 2019-2021. Ambulance officers had the highest incidence (24.9 per 1000 workers) and the highest growth rate. Nurses and midwives, and aged and disability care workers also had fast-growing incidence over the 9 years. Risk of psychological injury claims was highest among female workers and older adults. CONCLUSIONS: The increasing incidence and trend of psychological injury claims among HSC workers in New South Wales signify a growing public health issue. Greater efforts are needed to prevent work-related psychological injury in the HSC industry and support affected workers. The different patterns of psychological injury claims across occupations suggest that interventions should be tailored to each occupational group.

Mental health implications and psychologic factors in workers' compensation cases.

ABSTRACT: Work-related injuries can harm mental health and affect other facets of injured workers' lives. Clinicians must be aware of the problem of emotional distress and treat the whole patient after a workplace injury. More education and information are needed for clinicians, employers, and workers' compensation carriers so that injured workers can be properly screened for mental health issues and supported during treatment. Further research is needed to establish a protocol for early intervention to minimize the negative emotional and mental health effects of workplace injuries.

Return to Work Experiences of Ontario Public Safety Personnel with Work-Related Psychological Injuries.

PURPOSE: Public safety personnel (PSP) perform work that puts them at greater risk of psychological injury than the general public. PSP who subsequently develop posttraumatic stress disorder (PTSD) or other mental health conditions may need to take time off of work and use the workers compensation system. Very little is known about the experiences of PSP making this type of claim in Ontario to the Workplace Safety and Insurance Board (WSIB), or which healthcare professionals (HCP) PSP access as part of the treatment and return to work (RTW) process. This study captures the experiences of Ontario PSP in their RTW journeys, including with employers, WSIB, and HCPs. METHODS: A survey-based study was conducted, using email and social media platforms to distribute the survey to PSP across Ontario. Quantitative data were summarized using means and frequencies, and open text results were analyzed using qualitative framework analysis. RESULTS: 145 survey respondents met the inclusion criteria for the study. On a scale out of 5, PSP rated their experience with WSIB and employer support as poor on their first RTW attempt with an average rating of 2.93 and 2.46 respectively. The top three HCPs accessed by PSP were psychologists (61%), occupational therapists (OT; 60%) and general practitioners (GP; 44%). Respondents identified the cultural competence of HCPs in understanding their work demands and work culture as very important. CONCLUSIONS: To improve RTW experiences for PSP who make a workers compensation claim for a psychological injury, an increase in HCP cultural competence related to PSP work is indicated, as well as improved RTW processes and workplace support.

Sleep disturbances and disability following work-related injury and illness: Examining longitudinal relationships across three follow-up waves.

Despite the high burden of sleep disturbances among the general population, there is limited information on prevalence and impact of poor sleep among injured workers. This study: (a) estimated the prevalence of sleep disturbance following work-related injury; and (b) examined the longitudinal association between sleep disturbances and disability/functioning, accounting for reciprocal relationships and mental illness. Longitudinal survey data were collected from workers' compensation claimants with a time-loss claim in Victoria, Australia (N = 700). Surveys were conducted at baseline, 6 months and 12 months. Sleep disturbance was measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. Disability/functioning was based on self-reported activity limitations, participation restrictions and emotional functioning. Path models examined the association between disability/functioning and sleep. Mean sleep disturbance T-scores were 55.2 (SD 11.4) at 6 months, with 36.4% of the sample having a T-score of 60+. Longitudinal relationships were observed between disability (specifically, emotional functioning) and sleep disturbances across successive follow-up waves. For example, each unit increase in T2 emotional functioning (five-point scale) was associated with a 1.1 unit increase in T3 sleep disturbance (approximately 29-76 scale). Cross-lagged path models found evidence of a reciprocal relationship between disability and sleep, although adjustment for mental illness attenuated the estimates to the null. In conclusion, sleep disturbances are common among workers' compensation claimants with work injuries/illnesses. Given the links between some dimensions of disability, mental health and sleep disturbances, the findings have implications for the development of interventions that target the high prevalence of sleep problems among working populations.

Rejection of workers' compensation claims may increase depressive symptoms among firefighters with occupational injury: a nationwide study in South Korea.

OBJECTIVES: This study sought to examine whether the experience of occupational injuries was associated with depressive symptoms and whether the rejection of workers' compensation claims was associated with depressive symptoms among Korean firefighters. METHODS: We conducted a nationwide survey of 6793 Korean firefighters in 2015. Based on the experience of occupational injuries and workers' compensation claims over the past year, respondents were classified into four groups: "Not injured", "Injured, not applied", "Injured, applied, but rejected" and "Injured, applied, and accepted." Depressive symptoms over the preceding week were assessed using the 11-item version of the Centers for Epidemiologic Studies Depression Scale. RESULTS: Compared to firefighters who did not get injured, injured firefighters had a higher prevalence of depressive symptoms (PR 2.01, 95% CI 1.83, 2.22) after controlling for confounders including job assignment. Also, when we restricted the analysis to injured firefighters, a higher prevalence of depressive symptoms was observed among "Injured, applied, but rejected" (PR 1.70, 95% CI 1.11, 2.59) group, compared to "Injured, applied, and accepted" group. CONCLUSIONS: This finding suggests that rejection of workers' compensation claims, as well as the experience of occupational injuries, may increase the risk of depressive symptoms among Korean firefighters.

Risk of mental illness after the diagnosis of occupational injury or disease: a retrospective cohort study.

OBJECTIVES: As studies on mental disorders in victims of occupational injury or disease are limited, this study aims to evaluate the risk of, and factors associated with, the development of mental illness in patients with occupational injury or disease using insurance claims data from Taiwan. METHODS: This retrospective cohort study analyzed insurance records in Taiwan to identify 18,285 adults who experienced occupational injury or disease in 2002-2013 and 18,285 adults without occupational injury or disease who were matched by propensity score. The risks of mental disorders during a follow-up period of up to 2 years were estimated and compared between the two cohorts. RESULTS: After controlling for other variables, the odds of mental illness in patients with occupational injury or disease was significantly higher compared to patients without occupational injury or disease. Additional factors associated with higher odds of mental disorders included female gender, age ≥ 30 years (vs. 20-29 years), Charlson comorbidity index ≥ 1, occupation category of labor union member, soldier, insured by social security, religious group member (vs. private or government employee), lower premium-based monthly salary (≤ 576 US$), treatment at a district hospital or clinic (vs. medical center), treatment at a publically-owned or consortium-owned hospital (vs. private hospital), and central or southeast geographic location (vs. Taipei). The main types of mental illness were anxiety disorder (2.79%) and other psychoses (3.29%). CONCLUSION: The risk of mental illness slightly increased during the 2-year period after the diagnosis of occupational injury or disease.

Occupation-level automation probability is associated with psychosocial work conditions and workers' health: A multilevel study.

OBJECTIVE: Work automation is increasing worldwide, and the probability of job automation has been associated with workers' adverse health outcomes. This study aimed to examine the association of occupation-level automation probability with work stress and workers' health. METHODS: We used data from a national survey of 14,948 randomly selected general workers conducted in 2016. Job control and job demand were assessed by the Job Content Questionnaire, and working hours and job insecurity were self-reported. Health outcomes were measured according to burnout and work-related injury or disease. We derived automation probabilities for 38 occupational groups and conducted multilevel analyses to examine the associations between occupation-level automation probability and workers' safety and health after adjusting for psychosocial work conditions. RESULTS: Participants working in jobs with a high probability of automation were more likely to have low job control, higher job insecurity, and work-related injury and disease prevalence; whereas workers in jobs with a low automation probability had higher psychological and physical demands and burnout prevalence. Furthermore, automation probability significantly predicted workers' health after adjustment for demographic characteristics and psychosocial work conditions. CONCLUSIONS: Workers with low automation probability jobs may experience work stress other than that captured by traditional measures of job strain. Organizational approaches to improve employment security and psychosocial conditions are essential for workers' safety and health in the context of increasing job automation.

Prevalence of serious mental illness and mental health service use after a workplace injury: a longitudinal study of workers' compensation claimants in Victoria, Australia.

OBJECTIVES: Serious mental illness is common among those who have experienced a physical workplace injury, yet little is known about mental health service use in this population. This study aims to estimate the proportion of the workplace musculoskeletal injury population experiencing a mental illness, the proportion who access mental health services through the workers' compensation system and the factors associated with likelihood of accessing services. METHODS: A longitudinal cohort study was conducted with a random sample of 615 workers' compensation claimants followed over three survey waves between June 2014 and July 2015. The primary outcome was receiving any type of mental health service use during this period, as determined by linking survey responses to administrative compensation system records for the 18 months after initial interview. RESULTS: Of 181 (29.4%) participants who met the case definition for a serious mental illness at one or more of the three interviews, 75 (41.4%) accessed a mental health service during the 18-month observation period. Older age (OR=0.96, 95% CI 0.93 to 0.99) and achieving sustained return to work (OR=0.27, 95% CI 0.11 to 0.69) were associated with reduced odds of mental health service use. Although not significant, being born in Australia was associated with an increased odds of service use (OR=2.23, 95% CI 0.97 to 5.10). CONCLUSIONS: The proportion of injured workers with musculoskeletal conditions experiencing mental illness is high, yet the proportion receiving mental health services is low. More work is needed to explore factors associated with mental health service use in this population, including the effect of returning to work.

Self-reported Participation Restrictions Among Male and Female Veterans With Traumatic Brain Injury in Veterans Health Administration Outpatient Polytrauma Programs.

OBJECTIVES: To identify areas of most restricted self-reported participation among veterans with traumatic brain injury (TBI), explore associations among participation restriction and clinical characteristics, and examine differences in participation restrictions by sex. DESIGN: Retrospective cross-sectional design. SETTING: National VA Polytrauma System of Care outpatient settings. PARTICIPANTS: Veterans with a confirmed TBI event (N=6065). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): Mayo-Portland Participation Index (M2PI), a 5-point Likert-type scale with 8 items. Total score was converted to standardized T score for analysis. RESULTS: The sample consisted of 5679 male and 386 female veterans with ≥1 clinically confirmed TBI events (69% white; 74% with blast exposure). The M2PI items with greatest perceived restrictions were social contact, leisure, and initiation. There were no significant differences between men and women on M2PI standardized T scores. Wilcoxon rank-sum analyses showed significant differences by sex on 4 items: leisure, residence, employment, and financial management (all P<.01). In multinomial logistic regression on each item controlling for demographics, injury characteristics, and comorbidities, female veterans had significantly greater relative risk for part-time work and unemployment on the employment item and significantly less risk for impairment on the residence and financial management item. CONCLUSIONS: There was no significant difference between men and women. Veterans on M2PI standardized T scores, which masks differences in response patterns to individual items. Clinical teams should be encouraged to discuss perceived restrictions with patients and target these areas in treatment planning. Future work is needed to investigate the psychometric properties of the M2PI by biological sex.

Impact of Work-Related Burn Injury on Social Reintegration Outcomes: A Life Impact Burn Recovery Evaluation (LIBRE) Study.

OBJECTIVE: To examine differences in long-term social reintegration outcomes for burn survivors with and without work-related injuries. DESIGN: Cross-sectional survey. SETTING: Community-dwelling burn survivors. PARTICIPANTS: Burn survivors (N=601) aged ≥18 years with injuries to ≥5% total body surface area or burns to critical areas (hands, feet, face, or genitals). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Life Impact Burn Recovery Evaluation Profile was used to examine the following previously validated 6 scale scores of social participation: Family and Friends, Social Interactions, Social Activities, Work and Employment, Romantic Relationships, and Sexual Relationships. RESULTS: Older participants, those who were married, and men were more likely to be burned at work (P<.01). Burn survivors who were injured at work scored significantly lower on the Work and Employment scale score after adjusting for demographic and clinical characteristics (P=.01). All other domain scale scores demonstrated no significant differences between groups. Individuals with work-related injuries scored significantly worse on 6 of the 19 items within the Work and Employment scale (P<.05). These individuals were more likely to report that they were afraid to go to work and felt limited in their ability to perform at work. CONCLUSIONS: Burn survivors with work-related injuries report worse work reintegration outcomes than those without work-related injuries. Identification of those at higher risk for work reintegration challenges after burn injury may enable survivors, providers, employers, and insurers to better use appropriate resources to promote and target optimal employment outcomes.

Posttraumatic Stress Disorder Symptoms Contribute to Staff Perceived Irritability, Anger, and Aggression After TBI in a Longitudinal Veteran Cohort: A VA TBI Model Systems Study.

OBJECTIVE: To examine the relationship between staff perceived irritability, anger, and aggression and posttraumatic stress disorder (PTSD) in veterans with traumatic brain injury (TBI) of all severity levels. DESIGN: Longitudinal cohort design. SETTING: Veterans Affairs Polytrauma Transitional Rehabilitation Programs. PARTICIPANTS: Veterans and service members with TBI of all severity levels enrolled in the Veterans Affairs Polytrauma Rehabilitation Centers' Traumatic Brain Injury Model System national database (N=240). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Univariable and multivariable logistic regression modeling was used to examine the association between irritability, anger, and aggression and potential risk factors, including PTSD symptoms. Irritability, anger, and aggression was measured as a single construct using an item from the Mayo-Portland Adaptability Inventory-4 that was rated by program staff at admission and discharge from the inpatient rehabilitation program. PTSD symptoms were assessed using the PTSD Checklist-Civilian Version. RESULTS: PTSD symptoms uniquely predicted program staff-rated irritability, anger, and aggression at discharge even after controlling for severity of TBI, age, male sex, education, and annual earnings. The model explained 19% of the variance in irritability, anger, and aggression. CONCLUSIONS: When TBI severity and PTSD symptoms were considered simultaneously in a sample of veterans, only PTSD symptoms predicted staff-rated irritability, anger, and aggression. Given the negative outcomes linked with irritability, anger, and aggression, veterans may benefit from assessment and treatment of PTSD symptoms within rehabilitation settings.

Transcultural validation of the return-to-work self-efficacy scale in Korean patients with work-related injuries.

BACKGROUND: This study aimed to develop a Korean version of the Return-to-Work Self-Efficacy (RTWSE)-19 Scale using forward- and backward-translation and investigate the validity of the RTWSE Scale specifically for Korean workers with work-related injuries. METHODS: Participants were 202 injured workers who had filed a claim accepted by the workers' compensation system and had received medical rehabilitation at workers' compensation hospitals following a work-related musculoskeletal injury. Among these participants, 88.1% were male, 54.5% were over 45 years, 45.5% were manufacturing employees, and 54.5% were craft or machine operator and assemblers. The 19 item RTWSE-19 scale was developed by Shaw et al. and have three underlying subscales: (i) meeting job demands, (ii) modifying job tasks, and (iii) communicating needs to others. Statistical analysis included exploratory factor analysis (maximum likelihood estimation with oblique quartimin rotation), internal consistency reliability using Cronbach's alpha, and correlations with related measures: pain intensity; fear-avoidance beliefs; general health; depression; and general self-efficacy. RESULTS: Using exploratory factor analysis, three factors with 17 items were identified: meeting job demands, modifying job tasks, and communicating needs to others. The removal of two items in the modifying job tasks domain resulted in an increased reliability. The Korean version of the RTWSE-17 showed reasonable model fit (CFI = .963; TLI = .943; RMSEA = .068; SRMR = 0.029), satisfactory reliability (r = 0.925), no floor and ceiling effect, and construct validity. CONCLUSIONS: The Korean RTWSE-17 scale was found to possess good psychometric properties and could address different injury types ranging from fractures to amputations involved in sub-acute and rehabilitation phases in the Korean context. This study's findings provide insights for practitioners and researchers to return to work after rehabilitation in a Korean clinical and workplace setting.

Multimorbidity and quality of life after blast-related injury among US military personnel: a cluster analysis of retrospective data.

BACKGROUND: Blast injury emerged as a primary source of morbidity among US military personnel during the recent conflicts in Iraq and Afghanistan, and led to an array of adverse health outcomes. Multimorbidity, or the presence of two or more medical conditions in an individual, can complicate treatment strategies. To date, there is minimal research on the impact of multimorbidity on long-term patient-reported outcomes. We aimed to define multimorbidity patterns in a population of blast-injured military personnel, and to examine these patterns in relation to long-term quality of life (QOL). METHODS: A total of 1972 US military personnel who sustained a blast-related injury during military operations in Iraq and Afghanistan were identified from clinical records. Electronic health databases were used to identify medical diagnoses within the first year postinjury, and QOL was measured with a web-based assessment. Hierarchical cluster analysis methods using Ward's minimum variance were employed to identify clusters with related medical diagnosis categories. Duncan's multiple range test was used to group clusters into domains by QOL. RESULTS: Five distinct clusters were identified and grouped into three QOL domains. The lowest QOL domain contained one cluster with a clinical triad reflecting musculoskeletal pain, concussion, and mental health morbidity. The middle QOL domain had two clusters, one with concussion/anxiety predominating and the other with polytrauma. The highest QOL domain had two clusters with little multimorbidity aside from musculoskeletal pain. CONCLUSIONS: The present study described blast-related injury profiles with varying QOL levels that may indicate the need for integrated health services. Implications exist for current multidisciplinary care of wounded active duty and veteran service members, and future research should determine whether multimorbidity denotes distinct post-blast injury syndromes.

Concussion History, Reporting Behaviors, Attitudes, and Knowledge in Jockeys.

OBJECTIVE: To examine concussion history, knowledge, and attitudes among Irish professional and amateur jockeys. DESIGN: Cross-sectional survey. SETTING: Questionnaire was distributed through e-mails sent to all licensed jockeys, over social media and during professional and amateur race meetings. PARTICIPANTS: An average of 23.6% (12%-44%) Irish professional and amateur jockeys (n = 119) holding a license in 2017. MAIN OUTCOME MEASURES: Jockeys reported their previous concussion history, actions after their most recent concussion and responded to questions examining their knowledge and attitudes toward concussion. RESULTS: Amateur (32.4%) and professional (19.6%) jockeys, who were never medically diagnosed over their career, suspected that they had sustained a concussion. Jockeys displayed good knowledge of concussion signs and symptoms; yet, one in 2 jockeys would continue to ride out the same day if they suspected they had a concussion. They were less likely if they had a race that day. Reasons for continuing to ride include not considering a concussion as serious (85.7%); risk of losing the ride (84.0%); not wanting to let anyone down (77.8%); and considered it a sign of weakness (74.1%). Risky behavior was more common after a suspected concussion than a medically diagnosed concussion. CONCLUSIONS: Underreporting of concussions is proposed as a serious concern, and concussion understanding and attitudes can impact reporting. To address the issue of underreporting of concussions in Irish horseracing, there is a need to educate jockeys and the wider racing community on the importance of timely concussion assessments and access to appropriate management systems.

Factors associated with unsuccessful return-to-work following work-related upper extremity injury.

BACKGROUND: Returning to work following occupational injury is a key outcome for both workers' compensation boards and injured workers. Predictive factors for returning remain unclear. AIMS: To describe factors associated with unsuccessful return-to-work (RTW) in a hand injury population to identify target areas through which occupational rehabilitation programmes can help injured workers achieve successful RTW outcomes. METHODS: Demographic data, functional, pain and psychosocial scores were recorded for injured workers discharged between April 2011 and September 2015 from a multidisciplinary upper extremity treatment programme. The primary outcome of RTW status was assessed at programme discharge. Bivariate analyses and multivariable logistic regression were used to identify factors associated with being unable to RTW. RESULTS: Of 872 participants who met the inclusion criteria, 65% were male and the mean age was 46 (standard deviation [SD] 11) years. In unadjusted bivariate analyses, the group with an unsuccessful RTW outcome had higher mean baseline pain, catastrophizing and QuickDASH scores; a higher baseline prevalence of depression, and reported a high level of pain more frequently than those who were working at discharge. In the adjusted logistic regression model, not working at baseline, higher QuickDASH score and presence of depression at baseline were independently associated with unsuccessful work status outcome. CONCLUSIONS: Negative baseline work status, greater self-reported functional disability and presence of depression were associated with greater odds of unsuccessful RTW following a workplace upper extremity injury. Integrating mental healthcare provision with occupational rehabilitation is a potential programmatic approach to improve RTW.

A longitudinal study on psychological reactions and resilience among young survivors of a burn disaster in Taiwan 2015-2018.

AIM: To investigate the long-term psychological reactions and resilient process of the young survivors after a large-scale burn disaster of the Formosa Color Dust Explosion in Taiwan. DESIGN: Longitudinal study with follow-up interviews using standardized questionnaire during November 2015-June 2018. METHODS: The burn survivors received structured assessment in the four-wave interviews including the five-item Brief Symptom Rating Scale, nine-item Concise Mental Health Checklist, and two-item Patient Health Questionnaire for depressive symptoms and suicide risk assessment. Post-traumatic psychological symptoms were assessed through the four-item Startle, Physiological Arousal, Anger, and Numbness Scale, and six-item Impact of Event Scale. FINDINGS: The response rates were 65.1%, 74.2%, 76.9%, and 78.5% across the four-wave interviews among 484 burn survivors. The participants were mean-aged 23.1 years with just over half having 40% or more burn wounds in total body surface area. The respondents at each wave were similar in gender, age, and per cent of total body surface area burned. In the first 2 years of recovery, the respondents showed resilience in coping with stress of trauma under family and social support. While there was a decreasing trend of psychological symptoms over the first 2 years, hypnotic use and alcohol consumption remained at about 10% in the final interview, which were accompanied by psychological symptom recurrence. CONCLUSION: Young burn survivors recovered both psychologically and physically under supportive care and personal resilience in 2 years after the burn event, yet post-traumatic mental distress and coping efforts after 2 years during community reintegration should be detected and managed. Early prevention and detection of mental health deterioration is needed even after 2 years of burn disasters. IMPACT: The study demonstrated post-burn longitudinal changes on psychological reactions. Nursing staffs may help young burn survivors identify mental distress and stress management needs in the long-term psychological adaptation process.

A pilot study on salivary cortisol secretion and auditory P300 event-related potential in patients with physical disability-related stress.

Objective: To evaluate the stress level and attention in workers with physical disabilities-related stress.Methods: Morning salivary cortisol was used as a stress marker while the event-related potential during the performance of the auditory oddball paradigm was conducted to investigate the attentive ability to sound stimuli. Eighteen injured workers (IP) and eighteen unaffected healthy adults (CP) were recruited for this study with half being men and the other half women (aged 21-55). Behavioral performance measures including reaction time (RT), accuracy rate, and commission error as well as the latency and amplitude of P300 wave over the central (Cz), centroparietal (CPz), and parietal (Pz) electroencephalogram electrode sites were used to compare the two groups.Results: This study demonstrated significantly higher salivary cortisol levels, longer RT, less accuracy to respond to the target during the auditory oddball paradigm in the IP group as compared to CP group. In addition, a significant prolongation of the peak latency of auditory P300 wave over CPz electrodes was also detected in IP group.Conclusion: The increased cortisol levels found in the IP group reflect the alteration of the basal hypothalamic-pituitary-adrenal axis as a result of the stresses of living with a physical disability. Delayed RT and the decreased in accuracy together with changing in peak latencies of auditory P300 wave indicate the impairment of attention networks in IP. Our study revealed that the patients with permanent physical disability.

Development and Pilot Assessment of the PACE Tool: Helping Case Managers Identify and Respond to Risk Factors in Workers' Compensation Case Management.

Purpose The aim was to develop a tool to be applied by workers' compensation case managers to guide intervention and avoid delayed return to work. Methods The Plan of Action for a CasE (PACE) tool was developed based on a review of existing literature, focus groups with case managers and analysis of existing claims data. Combined with analysis of existing case manager practice, these sources were used to determine key constructs for inclusion in the tool to be aligned with the demands of case manager workload. Mapping of existing interventions was used to match risk identified by the tool with appropriate intervention. Results The final PACE tool consisted of 41 questions divided into Ready (worker), Set (employer) and Go (treating practitioner) categories. Questions in the tool were linked to appropriate case manager actions. Data collection was completed by case managers for 524 claims within the first 2 weeks of the claim being accepted. The most commonly identified risks for delayed RTW included both worker and employer expectations of RTW, as well as certification of capacity. Factor analysis identified two factors operating across the tool categories. Case managers reported benefits in using the tool, but reported it also increased their workload. Conclusions The PACE tool is a unique example of the implementation of risk identification in case management practice. It demonstrates that case managers are ideally placed to collect information to identify risk of delayed RTW. Future work will establish the impact of case-manager led intervention based on identified risks on outcomes for injured workers.

How Does Perceived Fairness in the Workers' Compensation Claims Process Affect Mental Health Following a Workplace Injury?

Purpose Mental health concerns are common after a workplace injury, particularly amongst those making a compensation claim. Yet there is a lack of research exploring the effect of modifiable elements of the return-to-work process on mental health. The aim of this study is to examine the impact of perceived injustice in the interactions between claim agents and claimants on mental health symptoms in the 12-month following a musculoskeletal (MSK) workplace injury. Methods A cohort of 585 workers compensation claimants in Victoria, Australia were interviewed three times over a 12-month period following a workplace MSK injury. Perceptions of informational and interpersonal justice in claim agent interactions were measured at baseline, and the Kessler Psychological Distress (K6) scale was administered as a measure of mental health at all three timepoints. Path analyses were performed to examine the direct and indirect effects of perceived justice at baseline on concurrent and future mental health, after accounting for confounding variables. Results Each 1-unit increase in perceptions of informational and interpersonal justice, indicating poorer experiences, was associated with an absolute increase of 0.16 and 0.18 in respective K6 mental health score at baseline, indicating poorer mental health on a 5-point scale. In addition, perceived justice indirectly impacted mental health at 6-month and 12-month, through sustained negative impact from baseline as well as increased risk of disagreements between the claim agent and claimant. Conclusions This finding has highlighted the importance of perceived justice in claim agent interactions with claimants in relation to mental health following a work-related MSK injury.

Return to Work and Ripple Effects on Family of Precariously Employed Injured Workers.

Purpose Work injury and return to work processes can have adverse effects on injured workers and their families. Family members may experience increased workloads, role reversals, dissolution of marriages or changes in relationships with children, as well as financial strain from loss of income. How these associations interact when the injured worker is precariously employed, however, is unknown. The aim of this study was to explore the impacts of work-related injury or illness as well as subsequent compensation and return to work processes on families and relationships of precariously employed workers. Methods Interviews were conducted with fifteen precariously employed injured workers recruited through on-line advertising, injured worker groups, and social media platforms in Ontario. Situational analysis was used to identify how family members were affected and their role throughout the injury process. Results Precariously employed injured workers felt caught between self-interested employers and disinterested workers' compensation. In some cases, this led to deteriorated mental health and well-being. The worker's difficulties with RTW challenged financial security of families and affected their day-to-day normal routines. While some workers received emotional and instrumental support from their family members, others had their families fall apart when chronic disability and unemployment proved to be too much. Conclusions This study addressed the complex ways that work injury and illness among precariously employed workers interact with family life and relationships. Findings illustrate how the income and employment insecurity associated with precarious employment has ripple effects on workers and their families when they become injured.
