Compensation System Experience at 12 Months After Road or Workplace Injury in Victoria, Australia

Workplace Injury Compensation and Mental Health and Self-Harm Outcomes: A Systematic Review

Workers' compensation systems aim to financially support injured workers. However, seeking compensation often leads to poorer physical and mental health outcomes. This review examines previous studies to investigate the relationship between workers' compensation and mental health and self-harm outcomes. A three-tiered search strategy across five databases identified studies that examined workers' compensation claims as an exposure or risk factor, with outcomes related to mental health, self-harm and suicidality. Nine full-text studies were included; however, heterogeneity limited generalizability. Most studies supported an association between pursuing compensation and poorer mental health and self-harm outcomes. Some studies attributed this to specific aspects of the system such as justice perception and navigation of the claims system. Findings suggest an association between workers' compensation and mental health or self-harm outcomes. Inconclusive findings highlight the need for further research. Understanding the psychiatric impacts of pursuing compensation is crucial to help formulate a more accessible compensation system.

Perceived Injustice in Cancer Survivors: Population-Specific Cut-Off Score and Relations with Personal Factors, Symptoms and Quality of Life-A Cross-Sectional Study

Fatigue and pain are the most common side effects impacting quality of life (QoL) in cancer survivors. Recent insights have shown that perceived injustice (PI) can play a substantial role in these side effects, but research on cancer survivors is scarce. Furthermore, guidelines for recognizing clinically relevant levels of PI in cancer survivors are missing. The aims of this study are to provide a clinically relevant cut-off for PI and to explore relationships between personal characteristics, symptoms, and QoL with PI. This multicenter, cross-sectional study uses the Injustice Experience Questionnaire (IEQ), Numeric Pain Rating Scale (NPRS), Patient-Specific Complaints (PSC), Multidimensional Fatigue Index (MFI), and European Organization for Research and Treatment of Cancer QoL Questionnaire-C30 (EORTC-QLQ-C30). A clinical cut-off for PI was identified based on the 75th percentile of IEQ scores. Univariate and multivariate regressions explored the relationship between PI and personal characteristics (sex, age, cancer type, treatment type), symptoms (pain intensity, fatigue), and QoL (daily activity complaints, cancer-related QoL). Cancer survivors (n = 121) were included, and a cut-off of 20 was identified. Significant indirect associations were found between chemotherapy, NPRS, PSC, MFI, and EORTC-QLQ-C30 with PI. In the multivariate model, only MFI (B = 0.205; 95% CI: 0.125-0.018) and age (B = 0.086; 95% CI: -0.191-0.285) maintained a significant association with PI.

Prognostic Role of Demographic, Injury and Claim Factors in Disabling Pain and Mental Health Conditions 12 Months after Compensable Injury

Identifying who might develop disabling pain or poor mental health after injury is a high priority so that healthcare providers can provide targeted preventive interventions. This retrospective cohort study aimed to identify predictors of disabling pain or probable mental health conditions at 12 months post-injury. Participants were recruited 12-months after admission to a major trauma service for a compensable transport or workplace injury (n = 157). Injury, compensation claim, health services and medication information were obtained from the Victorian Orthopaedic Trauma Outcome Registry, Victorian State Trauma Registry and Compensation Research Database. Participants completed questionnaires about pain, and mental health (anxiety, depression, posttraumatic stress disorder) at 12 months post-injury. One third had disabling pain, one third had at least one probable mental health condition and more than one in five had both disabling pain and a mental health condition at 12 months post-injury. Multivariable logistic regression found mental health treatment 3-6 months post-injury, persistent work disability and opioid use at 6-12 months predicted disabling pain at 12 months post-injury. The presence of opioid use at 3-6 months, work disability and psychotropic medications at 6-12 months predicted a mental health condition at 12 months post-injury. These factors could be used to identify at risk of developing disabling pain who could benefit from timely interventions to better manage both pain and mental health post-injury. Implications for healthcare and compensation system are discussed.

Health and return to work in the first two years following road traffic injury: a comparison of outcomes between compensation claimants in Victoria and New South Wales, Australia

BACKGROUND

People who sustain road traffic injuries often have poor health outcomes. While outcomes are often worse in people with a compensation claim, especially in fault-based schemes versus no-fault schemes, few studies have directly compared outcomes across scheme types.

OBJECTIVE

To compare health and work outcomes between people who had no compensation claim, a fault-based claim, or "no-fault" transport or workers compensation claim after hospitalisation for a road traffic injury.

METHODS

Participants aged >=18 years admitted to hospital in New South Wales or Victoria for >24 hours were recruited in two separate prospective cohort studies (N=1,034). People who died or sustained minor or very severe injuries were excluded. Groups included Compulsory Third Party (fault-based, n=128), no-fault Transport Accident Commission (TAC; n=454) and workers compensation claimants (n=73), or no claim (n=226). Outcomes at six, 12- and 24-months post-injury included health [SF-12 Mental Component Score (MCS) and Physical Component Score (PCS)], and return to work for people working pre-injury. Multivariable mixed effects linear and logistic regressions, adjusting for demographic and injury covariates, examined differences in health and work outcomes between claimant groups, with fixed effects of time and random effects of participant ID.

RESULTS

Health status was better in people with a no-fault TAC claim (MCS: m=50.62, 95%CI:49.62,51.62; PCS: m=40.49, 95%CI:39.46,41.52) or no claim (MCS: m=49.99, 95%CI:49.62,51.62; PCS: m=44.36, 95%CI:43.00,45.72), than people with a workers compensation (MCS: m=45.73, 95%CI:43.46,48.00; PCS: m=38.94, 95%CI:36.59,41.30) or fault-based CTP claim (MCS: m=41.34, 95%CI:39.54,43.13; PCS: m=35.64, 95%CI:33.78,37.49). Relative to fault-based CTP claimants, the odds of returning to work were higher for people with no claim (AOR=6.84, 95%CI:1.73,27.05) but did not differ for no-fault TAC (AOR=1.21, 95%CI:0.36,4.05) or workers compensation claimants (AOR=0.83,95%CI: 0.17,3.99). While people with a fault-based CTP claim had poorer mental and physical health and return to work after injury, they showed greater improvements in mental health, and similar levels of improvement in physical health and work participation over time to the other groups.

CONCLUSION

The patterns of health and work across scheme types provide important insights against which we can contrast the effects of future scheme designs on client outcomes.

Perceived fairness of claimants undergoing a work disability evaluation: Development and validation of the Basel Fairness Questionnaire

Background

There are currently no tools for assessing claimants’ perceived fairness in work disability evaluations. In our study, we describe the development and validation of a questionnaire for this purpose.

Method

In cooperation with subject-matter experts of Swiss insurance medicine, we developed the 30-item Basel Fairness Questionnaire (BFQ). Claimants anonymously answered the questionnaire immediately after their disability evaluation, still unaware about its outcome. For each item, there were four response options, ranging from “strongly disagree” to “strongly agree”. The construct validity of the BFQ was assessed by running a principal component analysis (PCA).

Results

In 4% of the questionnaires, the claimants’ perception on the disability evaluation was negative (below the median of the scale). The PCA of the items responses followed by an orthogonal rotation revealed four factors, namely (1) Interviewing Skills, (2) Rapport, (3) Transparency, and (4) Case Familiarity, explaining 63.5% of the total variance.

Discussion

The ratings presumably have some positive bias by sample selection and response bias. The PCA factors corresponded to dimensions that subject-matter experts had beforehand identified as relevant. However, all item ratings were highly intercorrelated, which suggests that the presumed underlying dimensions are not independent.

Conclusion

The BFQ represents the first self-administered instrument for measuring claimants’ perceived fairness of work disability evaluations, allowing the assessment of informational, procedural, and interactive justice from the perspective of claimants. In cooperation with Swiss assessment centres, we plan to implement a refined version of the BFQ as feedback instrument in work disability evaluations.

A Systematic Review of the Association Between Perceived Injustice and Pain-Related Outcomes in Individuals with Musculoskeletal Pain

Objective

A growing body of literature shows that justice-related appraisals are significant determinants of pain-related outcomes and prolonged trajectories of recovery. We conducted a systematic review of the literature assessing the relationship between perceived injustice and pain-related outcomes in individuals with musculoskeletal pain.

Design and Participants

A search of published studies in English in PubMed, PsychInfo, Embase, and Cochrane Database of Systematic Reviews from database inception through May 2019 was performed. Search terms included “perceived injustice,” “injustice appraisals,” “perceptions of injustice,” and “pain” or “injury.”

Results

Thirty-one studies met inclusion criteria. Data for a total of 5,969 patients with musculoskeletal pain were extracted. Twenty-three studies (71.9%) reported on individuals with persistent pain lasting over three months, and 17 studies (53.1%) reported on individuals with injury-related musculoskeletal pain. Significant associations were found between perceived injustice and pain intensity, disability and physical function, symptoms of depression and anxiety, post-traumatic stress disorder, quality of life and well-being, and quality of life and social functioning.

Conclusions

This systematic review summarizes the current evidence for the association between perceived injustice and pain-related outcomes. There is strong evidence that perceived injustice is associated with pain intensity, disability-related variables, and mental health outcomes. Implications and directions for future research are discussed.

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.

A systematic review of the association between fault or blame-related attributions and procedures after transport injury and health and work-related outcomes

Attributions of fault are often associated with worse injury outcomes; however, the consistency and magnitude of these impacts is not known. This review examined the prognostic role of fault on health, mental health, pain and work outcomes after transport injury. A systematic search of five electronic databases (Medline, Embase, CINAHL, PsycINFO, Cochrane Library) yielded 16,324 records published between 2000 and January 2018. Eligibility criteria were: adult transport injury survivors; prospective design; multivariable analysis; fault-related factor analysed; pain, mental health, general health or work-related outcome. Citations (n = 10,558, excluding duplicates) and full text articles (n = 555) were screened manually (Reviewer 1), and using concurrent machine learning and text mining (Reviewer 2; using Abstrackr, WordStat and QDA miner). Data from 55 papers that met all inclusion criteria were extracted, papers were evaluated for risk of bias using the QUIPS tool, and overall level of evidence was assessed using the GRADE tool. There were six main fault-related factors classified as: fault or responsibility, fault-based compensation, lawyer involvement or litigation, blame or guilt, road user or position in vehicle, and impact direction. Overall there were inconsistent associations between fault and transport injury outcomes, and 60% of papers had high risk of bias. There was moderate evidence that fault-based compensation claims were associated with poorer health-related outcomes, and that lawyer involvement was associated with poorer work outcomes beyond 12 months post-injury. However, the evidence of negative associations between fault-based compensation claims and work-related outcomes was limited. Lawyer involvement and fault-based compensation claims were associated with adverse mental health outcomes six months post-injury, but not beyond 12 months. The most consistent associations between fault and negative outcomes were not for fault attributions, per se, but were related to fault-related procedures (e.g., lawyer engagement, fault-based compensation claims).

The road to recovery for vulnerable road users hospitalised for orthopaedic injury following an on-road crash

BACKGROUND

Pedestrians, cyclists and motorcyclists are vulnerable to serious injury due to limited external protective devices. Understanding the level of recovery, and differences between these road user groups, is an important step towards improved understanding of the burden of road trauma, and prioritisation of prevention efforts. This study aimed to characterise and describe patient-reported outcomes of vulnerable road users at 6 and 12 months following orthopaedic trauma.

METHODS

A registry-based cohort study was conducted using data from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and included pedestrians, cyclists and motorcyclists who were hospitalised for an orthopaedic injury following an on-road collision that occurred between January 2009 and December 2016. Outcomes were measured using the 3-level EuroQol 5 dimensions questionnaire (EQ-5D-3 L), Glasgow Outcome Scale - Extended (GOS-E) and return to work questions. Outcomes were collected at 6 and 12 months post-injury. Multivariable generalized estimating equations (GEE), adjusted for confounders, were used to compare outcomes between the road user groups over time.

RESULTS

6186 orthopaedic trauma patients met the inclusion criteria during the 8-year period. Most patients were motorcyclists (42.8%) followed by cyclists (32.6%) and pedestrians (24.6%). Problems were most prevalent on the usual activities item of the EQ-5D-3 L at 6-months post-injury, and the pain/discomfort item of the EQ-5D-3 L at 12 months. The adjusted odds of reporting problems on all EQ-5D-3 L items were lower for cyclists when compared to pedestrians. Moreover, an average cyclist had a greater odds of a good recovery on the GOS-E, (AOR 2.75, 95% CI 2.33, 3.25) and a greater odds of returning to work (AOR = 3.13, 95% CI 2.46, 3.99) compared to an average pedestrian.

CONCLUSION

Pedestrians and motorcyclists involved in on-road collisions experienced poorer patient-reported outcomes at 6 and 12 months post-injury when compared to cyclists. A focus on both primary injury prevention strategies, and investment in ongoing support and treatment to maximise recovery, is necessary to reduce the burden of road trauma for vulnerable road users.

Financial and recovery worry one year after traumatic injury: A prognostic, registry-based cohort study

BACKGROUND

Levels of stress post-injury, especially after compensable injury, are known to be associated with worse long-term recovery. It is therefore important to identify how, and in whom, worry and stress manifest post-injury. This study aimed to identify demographic, injury, and compensation factors associated with worry about financial and recovery outcomes 12 months after traumatic injury.

METHODS

Participants (n = 433) were recruited from the Victorian Orthopaedic Trauma Outcomes Registry and Victorian State Trauma Registry after admission to a major trauma hospital in Melbourne, Australia. Participants completed questionnaires about pain, compensation experience and psychological wellbeing as part of a registry-based observational study.

RESULTS

Linear regressions showed that demographic and injury factors accounted for 11% and 13% of variance in financial and recovery worry, respectively. Specifically, lower education, discharge to inpatient rehabilitation, attributing fault to another and having a compensation claim predicted financial worry. Worry about recovery was only predicted by longer hospital stay and attributing fault to another. In all participants, financial and recovery worry were associated with worse pain (severity, interference, catastrophizing, kinesiophobia, self-efficacy), physical (disability, functioning) and psychological (anxiety, depression, PTSD, perceived injustice) outcomes 12 months post-injury. In participants who had transport (n = 135) or work (n = 22) injury compensation claims, both financial and recovery worry were associated with sustaining permanent impairments, and reporting negative compensation system experience 12 months post-injury. Financial worry 12 months post-injury was associated with not returning to work by 3-6 months post-injury, whereas recovery worry was associated with attributing fault to another, and higher healthcare use at 6-12 months post-injury.

CONCLUSIONS

These findings highlight the important contribution of factors other than injury severity, to worry about finances and recovery post-injury. Having a compensation claim, failure to return to work and experiencing pain and psychological symptoms also contribute to elevated worry. As these factors explained less than half of the variance in worry, however, other factors not measured in this study must play a role. As worry may increase the risk of developing secondary mental health conditions, timely access to financial, rehabilitation and psychological supports should be provided to people who are not coping after injury.

Traumatic injury and perceived injustice: Fault attributions matter in a "no-fault" compensation state

Background

Traumatic injury can lead to loss, suffering and feelings of injustice. Previous research has shown that perceived injustice is associated with poorer physical and mental wellbeing in persons with chronic pain. This study aimed to identify the relative association between injury, compensation and pain-related characteristics and perceived injustice 12-months after traumatic injury.

Methods

433 participants were recruited from the Victorian Orthopedic Trauma Outcomes Registry and Victorian State Trauma Registry, and completed questionnaires at 12–14 months after injury as part of an observational cohort study. Using hierarchical linear regression we examined the relationships between baseline demographics (sex, age, education, comorbidities), injury (injury severity, hospital length of stay), compensation (compensation status, fault, lawyer involvement), and health outcomes (SF-12) and perceived injustice. We then examined how much additional variance in perceived injustice was related to worse pain severity, interference, self-efficacy, catastrophizing, kinesiophobia or disability.

Results

Only a small portion of variance in perceived injustice was related to baseline demographics (especially education level), and injury severity. Attribution of fault to another, consulting a lawyer, health-related quality of life, disability and the severity of pain-related cognitions explained the majority of variance in perceived injustice. While univariate analyses showed that compensable injury led to higher perceptions of injustice, this did not remain significant when adjusting for all other factors, including fault attribution and consulting a lawyer.

Conclusions

In addition to the “justice” aspects of traumatic injury, the health impacts of injury, emotional distress related to pain (catastrophizing), and the perceived impact of pain on activity (pain self-efficacy), had stronger associations with perceptions of injustice than either injury or pain severity. To attenuate the likelihood of poor recovery from injury, clinical interventions that support restoration of health-related quality of life, and adjustment to the impacts of trauma are needed.
