Exploring Canadian Career Firefighters' Understanding of the Return-to-Work Process After Musculoskeletal Injuries.

PURPOSE: Firefighters perform dangerous and physically demanding work, increasing their risk of musculoskeletal injuries that can lead to work absences. Return-to-work procedures can help firefighters return-to-work sooner and safely. The purpose of this study was to explore what firefighters understand about return-to-work procedures in their workplaces, and what firefighters believe the facilitators and barriers to return-to-work are. METHODS: Thirty-eight Canadian career firefighters were recruited for semi-structured interviews. Qualitative descriptive methods were used to analyze the transcripts. Two researchers performed the inductive coding and thematic analysis. RESULTS: Five themes were identified: 1. Variation in the return-to-work process knowledge among firefighters based on their experiences; 2. Accessible medical resources and treatments to support injury recovery; 3. Light duties must be meaningful and suitable; 4. Pressures to return-to-work too soon may lead to negative consequences; and 5. Heavy physical demands of firefighting may become a barrier for return-to-work. 'Factors affecting RTW depended on personal experiences and context' was the overarching theme identified, as many reported facilitators for return-to-work were also reported as barriers in different contexts. There was a variation in the experiences and understanding of return-to-work. CONCLUSION: There is a lack of knowledge of the return-to-work processes. Firefighters require access to clear return-to-work policies and procedures and treatments that are targeted to firefighting duties to support recovery from injuries and regain physical abilities after an injury. Firefighters must be able to perform all essential duties before returning to firefighting work, as returning to work too soon can lead to further injury.

Scoping review of the occurrence and characteristics of firefighter exercise and training injuries.

OBJECTIVES: To summarize the current research on the occurrence of firefighter exercise and training injuries and to describe the nature of these injuries. METHODS: Scoping review methods were used to identify articles and extract information relevant to firefighter exercise and training injuries. Relevant articles were identified from MEDLINE, Web of Science, CINAHL, Embase, PubMed, and through hand-searching. RESULTS: A total of 1053 articles were identified, and 23 met the inclusion criteria. Nine studies were retrospective analyses of injury data, 13 studies used surveys to identify injuries in the past year, and 1 study reviewed U.S. firefighter injury reports. Three studies included both career and volunteer firefighters, 2 studies included career firefighters, 2 studies include volunteer firefighters, 1 study include recruits and 16 studies did not specify the career status. The occurrence of exercise and training injuries from 22 of the 23 studies ranged from 8.1 to 55.3% of reported injuries. One study found that 3 out of 15 fire departments identified exercise and training as the most common cause of their firefighter injuries. The 13 articles that reported the type of injuries identified musculoskeletal disorders as the most common type of injury (32% to 79% of reported injuries). The ankle, knee and leg were identified as the most commonly injured areas of the body. CONCLUSIONS: Training injuries are common in firefighters and must be prevented. Future research is needed to identify root causes of training injuries to guide prevention strategies.

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

PURPOSE: 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. METHODS: 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. RESULTS: 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 (37 days 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. CONCLUSIONS: 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.

Rasch analysis of the brief Michigan Hand Questionnaire in patients with thumb osteoarthritis.

BACKGROUND: The brief Michigan Hand Questionnaire (brief MHQ) is a 12-item self-reported measure of hand function for patients with hand disorders which has been validated using Classical Test Theory. Rasch analysis can provide more detailed psychometric information. The purpose of this Rasch analysis is to assess the psychometric properties of the brief MHQ for patients with thumb osteoarthritis, and to make recommendations for improvements to the questionnaire if needed.  METHODS: The Michigan Hand Questionnaire and demographic data were collected from 923 thumb osteoarthritis patients treated in specialized clinics for hand surgery and therapy in the Netherlands. Rasch analysis was performed on the 12 items of the brief MHQ using RUMM 2030 to assess the fit of the brief MHQ to the Rasch model. To determine fit, analysis of fit summary statistics, individual person fit and individual item fit were assessed. Threshold distributions were assessed to identify if any items required rescoring. The Person Separation Index was calculated to measure reliability of the questionnaire. Differential item functioning was assessed to identify item bias, and Principal Component Analysis was performed to identify unidimensionality and local dependence. RESULTS: The brief MHQ showed misfit (χ2 = 1312.5, p < 0.0001) with 6 items having disordered thresholds and 9 items requiring rescoring. After deleting 3 of the rescored items due to significant item fit residuals, the brief MHQ had an acceptable reliability (Cronbach's alpha = 0.79). Misfit to the model (χ2 = 49.6, p = 0.0001), multidimensionality (10.2% of t-tests were significant), and item bias from non-uniform differential item functioning for 7 items across many person variables were still found. CONCLUSION: Although no satisfactory solutions were found to correct the misfit to the Rasch model, it is recommended that the response options of the brief MHQ be rescored, and that items 6, 9 and 10 be removed. The lack of unidimensionality indicates that the items do not represent the singular construct of hand disability and that totalling the scores of the brief MHQ does not provide a valid measure of hand disability for people with thumb osteoarthritis. The 37-item Michigan Hand Questionnaire may provide a better assessment of hand disability for patients with thumb osteoarthritis.

The Quality, Readability, Completeness, and Accuracy of PTSD Websites for Firefighters.

Firefighters appear at an increased risk for post-traumatic stress disorder (PTSD). Because of PTSD-related stigma, firefighters may search for information online. The current study evaluated the quality, readability, and completeness of PTSD online resources, and to determine how the online treatment recommendations align with current evidence. Google.ca (Canada) searches were performed using four phrases: 'firefighter PTSD', 'firefighter operational stress', 'PTSD symptoms', and 'PTSD treatment'. The 75 websites identified were assessed using quality criteria for consumer health information (DISCERN), readability and health literacy statistics, content analysis, and a comparison of treatments mentioned to the current best evidence. The average DISCERN score was 43.8 out of 75 (indicating 'fair' quality), with 9 'poor' websites (16-30), 31 'fair' websites (31-45), 26 "good" websites (46-60), and nine excellent websites (61-75). The average grade level required to understand the health-related content was 10.6. The most mentioned content was PTSD symptoms (48/75 websites) and PTSD treatments (60/75 websites). The most frequently mentioned treatments were medications (41/75 websites) and cognitive behavioural therapy (40/75 websites). Cognitive behavioural therapy is supported by strong evidence, but evidence for medications appears inconsistent in current systematic reviews. Online PTSD resources exist for firefighters, but the information is challenging to read and lacks evidence-based treatment recommendations.
