Multivariable prediction models for the recovery of and claim closure related to post-collision neck pain and associated disorders

ObjectiveFew clinical prediction models are available to clinicians to predict the recovery of patients with post-collision neck pain and associated disorders. We aimed to develop evidence-based clinical prediction models to predict (1) self-reported recovery and (2) insurance claim closure from neck pain and associated disorders (NAD) caused or aggravated by a traffic collision.MethodsThe selection of potential predictors was informed by a systematic review of the literature. We used Cox regression to build models in an incident cohort of Saskatchewan adults (n = 4923). The models were internally validated using bootstrapping and replicated in participants from a randomized controlled trial conducted in Ontario (n = 340). We used C-statistics to describe predictive ability.ResultsParticipants from both cohorts (Saskatchewan and Ontario) were similar at baseline. Our prediction model for self-reported recovery included prior traffic-related neck injury claim, expectation of recovery, age, percentage of body in pain, disability, neck pain intensity and headache intensity (C = 0.643; 95% CI 0.634–0.653). The prediction model for claim closure included prior traffic-related neck injury claim, expectation of recovery, age, percentage of body in pain, disability, neck pain intensity, headache intensity and depressive symptoms (C = 0.637; 95% CI 0.629–0.648).ConclusionsWe developed prediction models for the recovery and claim closure of NAD caused or aggravated by a traffic collision. Future research needs to focus on improving the predictive ability of the models.

The utility of a safety climate scale among workers with a work-related permanent impairment who have returned to work.

Safety climate (SC) is a robust leading indicator of occupational safety outcomes. There is, however, limited research on SC among workers who have returned to work with a work-related permanent impairment. This study examined three propositions: (1) a two-level model of SC (group-level and organization-level SC) will provide the best fit to the data; (2) antecedent factors such as safety training, job demands, supervisor support, coworker support, and decision latitude will predict SC; and (3) previously reported associations between SC and outcomes such as reinjury, work-family conflict, job performance, and job security will be observed. A representative cross-sectional survey gathered information about experiences during the first year of work reintegration. About one year after claim closure, 599 interviews with workers were conducted (53.8% response rate). Confirmatory factor analyses were conducted to test the factor structure of the SC construct. Further, researchers used correlation analyses to examine the criterion-related validity. Consistent with general worker populations, our findings suggest the following: (1) the two-factor structure of SC outperformed the single-factor structure in our population of workers with a permanent impairment; (2) correlations demonstrate that workplace safety training, decision latitude, supervisor support, coworker support, and job demands could predict SC; and (3) SC may positively impact reinjury risk, work-family conflict, and may increase job performance and job security. Our study validated a two-factor SC scale among workers with a history of disabling workplace injury or permanent impairment who have returned to work. Practical applications of this scale will equip organizations with the necessary data to improve working conditions for this population.

Early Drug Prescription Patterns as Predictors of Final Workers Compensation Claim Costs and Closure: An Updated Analysis on an Expanded Cohort.

The aim of the study is to determine the associations of workers' compensation claim costs and return to work with drugs prescribed for early symptom management. Claims filed from 1998 to 2007 were followed for 10 years from the injury date. Drugs analyzed included gabapentin, pregabalin, antipsychotics, antidepressants, sedatives, benzodiazepines, carisoprodol, and opioids, controlling for initial reserve, sex, age, physical therapy, attorney involvement, and surgery. Gabapentin, antipsychotics, antidepressants, and sedatives used in the first 3 months after injury were significantly associated with higher claim cost (≥$100,000). All opioid morphine equivalent doses greater than or equal to 5 mg/d for the first 6 months was significantly associated with higher cost (≥$100,000) and not being released to work at end of third year after injury with dose-response relationships. Prescription patterns in the first 3 months or first 6 months of workers' compensation claim development may be used as predictors of claim outcomes.

A retrospective cohort analysis of return-to-work outcomes for cancer survivors using a digital coaching intervention.

1566 Background: Return-to-work (RTW) is a key unmet need for working age cancer survivors, with up to 40% failing to RTW 1 to 2 years post-diagnosis. This study sought to evaluate RTW outcomes of a multidisciplinary digital coaching intervention provided as routine employee support. Methods: A retrospective cohort analysis was conducted from October 2018 to February 2020 where cancer patients with more than 3 months absent from work were provided by their insurance carriers with a multidisciplinary intervention comprising digital resources and telephone calls with a health coach. A logit regression model was used to calculate a propensity score using covariates of age, gender, insurance benefit type, cancer diagnosis date and time from diagnosis. Participants were then matched on a 1:1 basis using the nearest-neighbour method without replacement to create a matched control group out of 1,856 participants who did not receive the intervention. Primary outcomes, derived from insurance-claims data as standard business practice, included rate and time to RTW, along with death and other reasons for claim closure. Results: 220 participants enrolled in the intervention, of which 125 met the criteria for analysis (median age 53, IQR 45-58, 91% female). These participants were matched with 125 controls (median age 53, IQR 47-59, 94% female). Median follow-up from cancer diagnosis was 79 weeks (IQR 60-106). Of the matched controls, 22 returned to work (17.6%) compared with 38 (30.4%) in the intervention group (P =.02). 19 matched controls died prior to claim closure (15.2%) compared with 13 in the intervention group (10.4%; P =.26). Finally, Kaplan-Meier method estimated median time for the first 15% of participants to RTW was 87.1 weeks for controls (CI 60.0-109.1 weeks) compared with 70.6 weeks for the intervention group (CI 52.6-79.6 weeks; P =.08). Conclusions: This study evaluated the impact of a digitally delivered coaching program in a real-world setting for cancer patients, demonstrating a 12.8% increase in RTW rate over 18 months compared to matched controls. These findings corroborate and add to the literature on cancer as a chronic and manageable disease in the workplace.

Workplace Wellness Program Interest and Barriers Among Workers With Work-Related Permanent Impairments.

Nearly half of U.S. workers have access to workplace wellness programs (WWPs), 58% of workers with access participate. The aim of this study was to assess interest in WWP participation and identify reasons for lack of interest among workers with work-related permanent impairments-a population at elevated risk of adverse health outcomes. Workers who returned to work after a work-related permanent impairment were interviewed 11 to 15 months after workers' compensation claim closure. Qualitative content analysis methods were used to code open-ended responses. Of 560 respondents, 51.4% expressed interest in WWP participation. Numerous adverse health and economic characteristics were associated with WWP interest, for example, interest was expressed by 63.3% of workers reporting fair/poor health status versus 47.1% reporting good/excellent; 56.9% of workers reporting moderate/severe pain versus 41.4% reporting mild/no pain; 64.7% of workers without health insurance versus 50.1% with health insurance; 69.0% of workers reporting depression versus 47.2% without depression; 70.4% of workers reporting obesity versus 48.0% without obesity; and 63.2% of workers often worried about expenses versus 46.9% reporting sometimes/never worried. Specific participation barriers were described by 34.2% of the 272 workers who were not interested. A majority of workers with work-related permanent impairments-particularly those with adverse health and economic characteristics-were interested in WWPs. Many workers who reported no interest cited participation barriers. Further research is needed to determine whether addressing such barriers would enhance equitable access. Those undertaking WWP planning, implementation, and outreach should ensure that WWPs are inclusive and serve workers with disabilities.

A Digital Coaching Intervention for Cancer Survivors With Job Loss: Retrospective Study.

BackgroundReturning to work is a key unmet need for working-age cancer survivors.ObjectiveThis study sought to evaluate return-to-work outcomes of a multidisciplinary intervention provided as routine employee support.MethodsIn a retrospective cohort analysis, patients with cancer and more than 3 months of absence from work were provided with an intervention consisting of digital resources and calls with a health coach. Propensity score matching was used to define a similar cohort of cancer patients absent from work, who were not offered the coaching intervention. The return-to-work rate as a percentage of all participants and secondary outcomes, such as the rate of death, were measured. The median time to return to work was compared between the cohorts using the Kaplan-Meier method.ResultsA total of 220 participants were enrolled in the intervention, of which 125 met the criteria for analysis. The median follow-up from cancer diagnosis was 79 weeks (IQR 60-106 weeks). In the matched control group, 22 (17.6%) participants returned to work compared with 38 (30.4%) in the intervention group (P=.02). Additionally, 19 (15.2%) matched controls died prior to claim closure compared with 13 (10.4%) in the intervention group (P=.26). The Kaplan-Meier estimated median time for the first 15% of the cohort to return to work was 87.1 weeks (95% CI 60.0-109.1 weeks) for the matched control group compared with 70.6 weeks (95% CI 52.6-79.6 weeks; P=.08) for the intervention group.ConclusionsPatients receiving a remotely delivered coaching program in a real-world setting returned to work at a higher frequency than did control participants receiving usual care.

Identifying predictors of return to work and the duration of time off work in first responders affected with musculoskeletal injuries or mental health issues.

To identify predictors of return to work, duration of time off work, and claim closure for first responders experiencing injuries or illnesses, and summarize the claim data. First responder claims collected between January 2012 and July 2017 were obtained from a disability management company. Known predictors of return to work were extracted from the data including age, sex, diagnosis, years of service, claim lag, medical report lag, and the return-to-work duties. Survival analyses were performed to identify predictors of return to work and claim closure using the Cox proportional regression analysis. Log-rank tests were performed to identify predictors that affected the rate of return to work and claim closure. Summary statistics were performed for the injury and return-to-work data. 60 of the 67 (89.6%) identified first responders returned to work within the data collection period. Musculoskeletal injuries predicted an increased likelihood of returning to work (hazard ratio = 2.0, 95%CI = 1.14-3.60) and a shorter duration of time off work (37days on average) compared to mental health issues. Everyday of claim lag and medical report lag predicted a 2% decrease in likelihood of return to work. Returning to work was the only predictor of claim closure. 45 (67.2%) first responders returned to their pre-absence duties. 22 (32.8%) mental health claims and 45 (67.2%) injury claims were identified. 89.6% of first responders returned to work, although only 67.2% returned to their pre-absence duties. Predictors of return to work included injury type, as first responders with musculoskeletal injuries returned to work sooner, and claim and medical lag delayed the return to work.

Association Between Depressive Symptoms or Depression and Health Outcomes for Low Back Pain: a Systematic Review and Meta-analysis.

Study results vary on whether depressive symptoms are associated with worse prognosis for low back pain (LBP). We assessed the association between depressive symptoms or depression and health outcomes in persons with LBP. We searched MEDLINE, Embase, CINAHL, and PsycINFO from inception to June 2020. Eligible studies were cohort and case-control studies assessing the association between depressive symptoms (questionnaires) or depression (diagnoses) and health outcomes in persons aged ≥16 years with LBP in the absence of major pathology. Reviewers independently screened articles, extracted data, and assessed risk of bias using the Quality in Prognosis Studies tool. We classified exploratory versus confirmatory studies based onphases of prognostic factor investigation. We conducted random-effects meta-analyses and descriptive synthesis where appropriate. Of 13,221 citations screened, we included 62 studies (63,326 participants; 61 exploratory studies, 1 confirmatory study). For acute LBP, depressive symptoms were associated with self-reported disability (descriptive synthesis: 6 studies), worse recovery (descriptive synthesis: 5 studies), and slower traffic injury-related claim closure (1 study), but not pain or work-related outcomes. Depressive symptoms were associated with greater primary healthcare utilization for acute LBP (1 confirmatory study). For chronic LBP, depressive symptoms were associated withhigher pain intensity (descriptive synthesis: 9 studies; meta-analysis: 3 studies, 2902 participants, β=0.11, 95% confidence interval (CI) 0.05-0.17), disability (descriptive synthesis: 6 studies; meta-analysis: 5 studies, 3549 participants, β=0.16, 95% CI 0.04-0.29), and worse recovery (descriptive synthesis: 2 studies; meta-analysis: 2 studies, 13,263 participants, relative risk (RR)=0.91, 95% CI 0.88-0.95), but not incident chronic widespread pain (1 study). Depressive symptoms may be associated with self-reported disability and worse recovery in persons with acute and chronic LBP, and greater primary healthcare utilization for acute LBP. Our review provides high-quality prognostic factor information for LBP. Healthcare delivery that addresses depressive symptoms may improve disability and recovery in persons with LBP. Confirmatory studies are needed to assess the association between depressive symptoms and health outcomes in persons with LBP. PROSPERO database (CRD42019130047).

Workplace improvements to support safe and sustained return to work: Suggestions from a survey of workers with permanent impairments.

Roughly 10% of occupational injuries result in permanent impairment. After initial return to work (RTW), many workers with permanent impairments face RTW interruption due to reinjury, unstable health, disability, and layoff. This study used open-ended survey data to: (1) explore workplace factors identified by workers as important levers for change, some of which may previously have been unrecognized; and (2) summarize workers' suggestions for workplace improvements to promote sustained RTW and prevent reinjury. This study included data from workers' compensation claims and telephone surveys of 582 Washington State workers who had RTW after a work-related injury involving permanent impairment. The survey was conducted in 2019, about a year after claim closure. We used qualitative content analysis methods to inductively code open-ended survey responses. The most frequent themes were: safety precautions/safer workplace (18.1%), adequate staffing/appropriate task distribution (16.2%), and safety climate (14.1%). Other frequent themes included ergonomics, rest breaks, job strain, predictability and flexibility in work scheduling practices, employer response to injury, social support, communication, and respect. Many workers reported that they were not listened to, or that their input was not sought or valued. Workers often linked communication deficiencies to preventable deficiencies in safety practices, safety climate, and RTW practices, and also to lack of respect or distrust. In counterpoint, nearly one-third of respondents reported that no change was needed to their workplace. Policies and interventions targeting worker-suggested workplace improvements may promote safe and sustained RTW, which is essential for worker health and economic stability.

Workplace Organizational and Psychosocial Factors Associated with Return-to-Work Interruption and Reinjury Among Workers with Permanent Impairment.

Roughly 10% of occupational injuries result in permanent impairment and a permanent partial disability (PPD) award. After initial return to work (RTW) following a work injury, many workers with permanent impairment face RTW interruption (breaks in ongoing employment due to reinjury, poor health, disability, lay-off, etc.). Most RTW and reinjury research has focused on worker-level risk factors, and less is known about contextual factors that may be amenable to workplace or workers' compensation (WC)-based interventions. The aim of this study was to identify modifiable organizational and psychosocial workplace factors associated with (i) RTW interruption and (ii) reinjury among workers with a permanent impairment. This retrospective cohort study included WC claims data and survey data for 567 injured workers who RTW at least briefly after a work-related injury that resulted in permanent impairment. Workers were interviewed once by phone, 11-15 months after WC claim closure with a PPD award. Logistic regression models were used to estimate associations between each workplace factor of interest and each outcome, controlling for whole body impairment percentage, gender, age, nativity, educational level, State Fund versus self-insured WC coverage, employer size, union membership, industry sector, and employment duration of current/most recent job. Twelve percent of workers had been reinjured in their current or most recent job, 12% of workers were no longer working at the time of interview, and <1% of workers reported both outcomes. The most frequently reported reason for RTW interruption was impairment, disability, and/or pain from the previous work injury. Lower reported levels of safety climate, supervisor support, and ability to take time off work for personal/family matters were significantly associated with both RTW interruption and reinjury. Inadequate employer/health care provider communication, perceived stigmatization from supervisors and/or coworkers, and lower levels of coworker support were significantly associated with RTW interruption but not with reinjury. Discomfort with reporting an unsafe situation at work, absence of a health and safety committee, and higher job strain were significantly associated with reinjury, but not with RTW interruption. Inadequate safety training and lack of needed job accommodations were not significantly associated with either outcome. There were no notable or statistically significant interactions between workplace factors and degree of impairment, and no consistent direction of association. This study provides evidence that several potentially modifiable organizational and psychosocial factors are associated with safe and sustained RTW among injured workers with work-related permanent impairment. The lack of interaction between any of these workplace factors and degree of impairment suggests that these findings may be generalizable to all workers, and further suggests that workplace interventions based on these findings might be useful for both primary and secondary prevention. Though primary prevention is key, secondary prevention efforts to sustain RTW and prevent reinjury may reduce the considerable health, economic, and social burden of occupational injury and illness.

Initial return to work and long-term employment patterns: Associations with work-related permanent impairment and with participation in workers' compensation-based return-to-work programs.

Roughly 10% of injured workers experience work injuries that result in permanent impairment and a permanent partial disability (PPD) award. This study aimed to characterize and quantify long-term employment outcomes for injured workers, by the degree of whole body impairment (WBI) and by participation in several workers' compensation (WC)-based return-to-work (RTW) programs. A retrospective cohort of 43,968 Washington State workers were followed for up to 10 years after WC claim closure (2009-2017). Degree of impairment was classified as: (1) no PPD award, (2) PPD award with WBI < 10%, or (3) PPD award with WBI ≥ 10%. State wage files were used to construct employment outcomes for regression, modeling: (1) time to first RTW, (2) time to first RTW interruption, (3) RTW volatility, and (4) employment gaps. Wage patterns and employment outcomes differed significantly by the degree of impairment. Compared to other workers, workers with WBI ≥ 10% had delayed RTW, shorter average times to first RTW interruption, and higher rates of both RTW interruptions and quarters without wages. Time to first RTW averaged over a year, increasing with the degree of impairment. About 9% overall-and 27% of workers with ≥10% WBI-had no observed wages after claim closure. In adjusted models, workers with WBI ≥ 10% had significantly poorer employment outcomes, compared to workers with no PPD award (p < 0.001). State wage files provide an efficient approach to identifying RTW patterns. Workers with permanent impairment were at substantially higher risk of poor employment outcomes. WC-based RTW programs may promote better employment outcomes.

Factors influencing duration of compensation following road traffic crash injury in older vs younger adults.

To identify factors independently associated with late claim closure, a proxy for recovery, in older (65+years) compared to younger (17-64years) adults following road traffic crash injury (RTI). Multivariable analysis of statewide compensation data from New South Wales (NSW), Australia, for NSW residents aged ≥17years injured in a non-catastrophic RTI between July 2010 and June 2013 with finalised claims (n=16687). Legal representation was the dominant factor independently associated with late claim closure in both age groups. However, the odds were doubly high for the younger group (younger: AOR 8.46, 95% CI 7.7-9.4; older: AOR 3.95, 95% CI 3.1-5.0). Median time to claim closure was shorter for older people. Older (and younger) claimants with legal representation are at increased risk of late claim closure and can be readily identified within routinely collected compensation data, enabling delivery of targeted strategies or supports early in the claims process.

Workforce Reintegration After Work-Related Permanent Impairment: A Look at the First Year After Workers' Compensation Claim Closure.

Purpose The purpose of this study was to descriptively quantify experiences of injured workers with permanent impairment during their first year of work reintegration. Methods A representative survey was conducted to characterize health, disability, pain, employment, reinjury, and economic outcomes for 598 workers with permanent impairment who had returned to work during the year after workers' compensation claim closure. Survey responses were summarized by degree of whole body impairment (< 10% vs. ≥ 10%). Results Injured workers who had returned to work reported that permanent impairment made it difficult to get a job (47%) and to keep their job (58%). A year after claim closure, 66% reported moderate to very severe pain; 40% reported pain interference with work. About 13% reported new work injuries; over half thought permanent impairment increased their reinjury risk. Asked to compare current to pre-injury work status, workers with a higher degree of impairment more frequently reported working fewer hours (OR 1.60; 95% CI 1.06, 2.42), earning less (OR 1.56; 95% CI 1.04, 2.36), and being at higher risk of losing their current job due to their impairment (OR 1.66; 95% CI 1.01, 2.71). Conclusions Injured workers with permanent impairment face long-term challenges related to health limitations, chronic pain, work reintegration, and economic impacts. Workers with a higher degree of impairment more frequently reported several economic and job security challenges. Developing workplace and workers' compensation-based interventions that reduce return-to-work interruption and reinjury for workers with permanent impairment should be prioritized as an important public health and societal goal.

Factors influencing outcomes among patients with whiplash-associated disorder: A population-based study in Japan.

IntroductionOnly a few, large population-based studies, have reported on whiplash-associated disorder (WAD). However, none of them have investigated the influence of crash severity on WAD outcome. In the present study, we aimed to determine whether crash severity predicts outcomes among patients with no-fault government insurance for acute WAD.MethodsWe utilized data from a compulsory, no-fault government automobile liability insurance agency in Japan. Individuals involved in a car accident between April 2001 and June 2015 with residual disabilities reported at the end of the treatment between October 2014 and September 2015 were included. Crash severity was assessed based on property damage costs, size of the other vehicle (large car, medium car, small car, or two-wheeled vehicles), and collision types (rear-end collision, contact with vehicle moving in the same direction, or in the opposite direction). Outcomes included the time to claim closure and the number of treatment visits.ResultsWe analyzed data for a total of 52,251 individuals (28,571 male and 23,680 female) with a median age of 44 years (range: 2–95 years). The median time to claim closure was 220 days (range: 1–4,938 days), and the median number of treatment visits was 102 (range: 1–2,492). There was no significant association between outcomes and property damage costs or size of the other vehicle. Collision types exhibited no consistent association with outcomes. However, older age and affected body parts, in addition to the neck, were independent risk factors for delayed claim closure and a large number of visits, although, all odds ratios were low (often less than 2.0).ConclusionsThere was no obvious association of outcomes with property damage costs, size of the other vehicle, or collision types in acute WAD patients. Further studies should investigate the influence of psychological factors, compensation systems, and cultural conditions.

Association of Opioid, Anti-Depressant, and Benzodiazepines With Workers' Compensation Cost: A Cohort Study.

Antidepressants, benzodiazapines, and opioid medications are used to manage the pain, anxiety, or depression associated with workplace injuries. To evaluate the impact of these medications on workers' compensation costs and time lost from work. A cohort of 22,383 indemnity claims from 2008 to 2013 were evaluated for the association of prescribed medications on claim cost and delayed claim closure controlling for confounders. Claims with anti-depressant, opioid, or benzodiazepine prescriptions were 2.24 (95% CI: 2.00 to 2.51), 1.14 (95% CI: 1.02 to 1.27), and 1.38 (95% CI: 1.23 to 1.54) times more likely to remain open at the end of the study. The concurrent treatment of pain, depression or anxiety, and occupational injuries are associated with large increases in claim cost and delayed return to work.

Is Preexisting Cervical Disk Degeneration a Prognostic Factor in Whiplash-associated Disorders?

This is a retrospective control study. We aimed to determine whether preexisting cervical disk degeneration is a prognostic factor in Whiplash-associated disorder (WAD). WAD is a common injury of traffic accident and has a broad range of prognoses. Although numerous studies have investigated prognostic factors in WAD, few have evaluated the effect of preexisting disk degeneration. This study involved 45 consecutive patients with grade I or II WAD having advanced disk degeneration (at least 1 disk of Miyazaki grade≥III on magnetic resonance imaging) and a control cohort of 52 patients with no or mild disk degeneration (all disks having Miyazaki grades≤II). Clinical assessment included pain severity (assessed by the visual analog scale), neck pain-related disability (assessed by the neck disability index), and physical and mental health condition [assessed by the short-form 36 (SF-36) physical composite score and SF-36 mental composite score, respectively]. Changes in each parameter were evaluated at baseline and at 3-month, 6-month, and 1-year follow-ups and compared between the 2 groups. There were no differences between the 2 groups regarding demographics and baseline outcome parameters (all P>0.05). There were also no differences in improvement in visual analog scale for neck pain, neck disability index, SF-36 physical composite score, or SF-36 mental composite score between the 2 groups (all P>0.05) for each visit. The number of claim closures was significantly lower among patients with advanced degeneration than among controls at 6-month and 1-year follow-ups (P=0.004 and 0.006, respectively). In the present study, the clinical presentation and prognosis of WAD were not affected by preexisting disk degeneration. However, claim closure was delayed in patients with preexisting disk degeneration. These results suggest that misunderstanding of disk degeneration on magnetic resonance imaging may create persistent illness and lead to continued compensation in WAD.

The relationship between insurance claim closure and recovery after traffic injuries for individuals with whiplash associated disorders

Purpose: The purpose of this study was to determine if time to claim closure was similar to time to self-reported recovery in a no fault motor vehicle collision insurance system.Method: A prospective cohort of traffic injured adults with a whiplash-associated disorder (WAD) was assembled. We excluded participants who applied for benefits after 42 days of the collision, who were in hospital for more than two days and participants who were not followed up at least once after their injury. Questionnaires were completed at baseline, six weeks, three-, six-, nine- and 12-months after the collision.Results: The mean age of the cohort was 39 years and 66% were female. The mean number of days until claim closure and for self-reported recovery was 291days and 134 days, respectively. We found those who had their claim closed at each follow-up period had lower levels of disability and were more likely to report they were recovered than participants with open claims.Conclusion: We conclude that time to claim closure could be used as an outcome measure in traffic collision; however, this measure should be used with caution since it over-estimates the true time to recovery.Implications for RehabilitationTime to claim closure as an outcome measure for whiplash-associated disorders has been criticized in the literature because it is thought that closure is not reflective of the health status of the individual.We found that claim closure was associated with lower levels of disability, but the time to claim closure was significantly longer than the time to self-reported recovery.Time to claim closure may be used with caution as a “proxy” measure of recovery from an injury; however, it must be noted that it over-estimates the true time of recovery

Predictors of time to claim closure following a non-catastrophic injury sustained in a motor vehicle crash: a prospective cohort study.

BackgroundResearch suggests that exposure to the compensation system (including time to case closure) could adversely influence a persons’ recovery following injury. However, the long-term predictors of time to claim closure following minor road traffic injuries remain unclear. We aimed to assess a wide spectrum of factors that could influence time to claim closure (socio-demographic, compensation-related, health, psychosocial and pre-injury factors) over 24 months following a non-catastrophic injury.MethodsProspective cohort study of 364 participants involved in a compensation scheme following a motor vehicle crash. We used a telephone-administered questionnaire to obtain information on potential explanatory variables. Information on time to claim closure was obtained from an insurance regulatory authority maintained database, and was classified as the duration between the crash date and claim settlement date, and categorized into < 12 (early), > 12–24 (medium) and > 24 months (late).ResultsJust over half of claimants (54 %) had settled their claim by 12 months, while 17 % and 30 % took > 12–24 months and > 24 months for claim closure, respectively. Whiplash at baseline was associated with claim closure time of > 12–24 months versus < 12 months: multivariable-adjusted OR 2.38 (95 % CI 1.06–5.39). Claimants who were overweight/obese versus normal/underweight at the time of injury were ~3.0-fold more likely to settle their claim at > 12–24 months than < 12 months. Consulting a lawyer was associated with a 10.4- and 21.0-fold increased likelihood of settling a claim at > 12–24 months and > 24 months, respectively. Each 1-unit increase in Orebro Musculoskeletal Pain Screening Questionnaire scores at baseline was associated with greater odds of both medium (> 12–24 months) and delayed claim settlement date (> 24 months): multivariable-adjusted OR 1.04 (95 % CU 1.01–1.07) and 1.02 (95 % CI 1.00–1.05), respectively.ConclusionsAround a third of claimants with a minor injury had not settled by 24 months. Health-related factors and lawyer involvement independently influenced time to claim closure.

The long-term burden of work-related carpal tunnel syndrome relative to upper-extremity fractures and dermatitis in Washington State.

Carpal tunnel syndrome (CTS) is among the most burdensome of all musculoskeletal disorders as measured by workers' compensation claims costs and lost earnings. But the burden of CTS extends beyond direct claim costs. A survey covering health, social, economic and work-related outcomes was administered to 1,255 injured workers whose Washington State Fund workers' compensation claims had closed 6 years previously. Logistic and linear regression methods were used to model the outcomes of CTS claimants across four separate outcome domains. Workers diagnosed with CTS suffer substantial deficits across all four outcome domains as compared to the two comparison groups of claimants. Former CTS claimants were almost twice as likely not to be working as compared to the fractures cohort. A comprehensive measurement of the burden of CTS shows losses extend beyond direct claims costs to include continuing pain, loss of function, adverse financial impacts and household disruption which extend long after claim closure.

Associations with duration of compensation following whiplash sustained in a motor vehicle crash

ContextContinued exposure to compensation systems has been reported as deleterious to the health of participants. Understanding the associations with time to claim closure could allow for targeted interventions aimed at minimising the time participants are exposed to the compensation system. Study objectiveTo identify the associations of extended time receiving compensation benefits with the aim of developing a prognostic model that predicts time to claim closure. Study designProspective cohort study in people with whiplash associated disorder. Outcome measuresTime to claim closure, in a privately underwritten fault based third party traffic crash insurance scheme in New South Wales, Australia. MethodCox proportional hazard regression modelling. ResultsOf the 246 participants, 25% remained in the compensation system longer than 24 months with 15% remaining longer than three years. Higher initial disability (Functional Rating Index≥25 at baseline) (HRR: 95% CI, 1.916: 1.324–2.774, p<0.001); and lower initial mental health as measured by SF-36 Mental Component Score (HRR: 95% CI, 0.973: 0.960–0.987, p<0.001) were significantly and independently associated with an increased time-to-claim closure.Shorter time to claim closure was associated with having no legal involvement (HRR: 95% CI, 1.911: 1.169–3.123, p=0.009); and, not having a prior claim for compensation (HRR: 95% CI, 1.523: 1.062–2.198, p=0.022). ConclusionsHealth and insurance related factors are independently associated with time to claim closure. Both factors need to be considered by insurers in their assessment of complexity of claims. Interventions aimed at minimising the impact of these factors could reduce claimants’ exposure to the compensation system. In turn insurers can potentially reduce claims duration and cost, while improving the health outcomes of claimants.
