BackgroundGlobally, road transport accidents contribute significantly to mortality and burden of disability. Up to 50 million people suffer a transport-related non-fatal injury each year, which often leads to long-term disability. A substantial number of people with minor injuries struggle to recover and little is known about the factors leading to poor or non-recovery. The aim of this paper is to present a systematic review of biopsychosocial factors related to poor or non-recovery after a minor transport-related injury.Methods and findingsStudies were selected through searches of PubMed, Medline, Embase, and Cochrane library. Methodological quality was assessed using a Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklist for quantitative cohort studies and Standards for Reporting Qualitative Research (SRQR) checklist for qualitative articles. Data were extracted using the Cochrane data extraction tool based on the biopsychosocial model of health (BPS). In total, there were 37 articles included. However, heterogeneity of the techniques and tools used to assess factors and outcomes across studies meant that pooling of results to determine biopsychosocial factors most predictive of poor or non-recovery was not possible. Hence, a narrative synthesis was conducted and shown multiple factors to be associated with poorer outcomes or non-recovery, most being identified in the biological and psychological domain of the BPS model. Factors that were the most representative across studies and have shown to have the strongest associations with poor or non-recovery were high initial pain intensity, pain duration and severity, pre-accident physical and mental health status and pain catastrophising.ConclusionsThis review demonstrates the complexity of recovery and a challenge in reporting on predictors of recovery. It is evident that a range of multi-factorial biopsychosocial factors impact recovery. These factors are often inter-connected and multi-faceted and therefore, it was not feasible to select or focus on one single factor. In defining the most predictive factors, further research is required, yet the consensus around which tools to use to measure recovery outcomes is needed and is highly recommended. Regardless of the descriptive nature, the review demonstrated that high levels of post-injury pain are associated with poorer outcomes such as chronic pain and physical and mental disability. Therefore, early targeting of modifiable factors such as pain, pain catastrophizing and arising comorbidities such as PTSD, depression and anxiety may assist in reducing chronic pain and ongoing related disabilities.Systematic review trial registration numberSystematic review protocol was registered in International Prospective Register for Systematic Reviews (PROSPERO) on 14 December 2016.

ObjectiveThe aim of the study was to understand the recovery phenomena and to explore participants' perspectives on the biopsychosocial facilitators and barriers affecting their recovery after a minor transport injury.MethodsA qualitative method was used involving semi‐structured interviews with 23 participants who sustained a minor transport injury. Interviews and analysis were guided by the biopsychosocial model (BPS) of health. The outcomes were themes capturing biopsychosocial barriers to, and personal experiences of, recovery using a previously defined framework.ResultsThe themes indicate that recovery is a multifaceted phenomenon affected by comorbidities such as chronic pain, depression and anxiety. A range of subsequent complexities such as the inability to self‐care and undertaking daily domestic duties, and incapacity to participate in recreational activities were major barriers to recovery. These barriers were found to be an on‐going source of frustration, dissatisfaction and a perceived cause of depressive symptomatology in many participants. Most participants reported mixed feelings of the care received. Other common issues raised included a lack of understanding of the assessment time, regular follow‐up, guidance and on‐going support.ConclusionThis study revealed that recovery after a minor transport‐related injury was a challenging, complex, demanding and a long‐term process for the individuals in this study. Findings from this limited cohort suggested that, for participants to return to their pre‐accident health status, a more coordinated approach to information and care delivery may be required.

Injuries from transport accidents are heterogeneous and recovery processes complex and challenging for people, regardless of the severity of injury sustained. Multiple factors influence the recovery trajectory, including pain, poor pre-accident health state, psychological comorbidities, socioeconomic disadvantage and, in some instances, financial compensation. In particular, the results on the effect of financial compensation on health outcomes following musculoskeletal injury remain controversial, indicating that further research is needed to understand the possible barriers and complexities involved in compensation processes and service delivery. This qualitative study investigated compensation-related barriers and found that recovery is indeed impacted by numerous challenges in using compensation services after traffic accident. To overcome these issues, it is recommended that a person-centred approach is used as foundation to inform decision-making for interventions aimed at improving recovery outcomes. An improved recovery management, communication and adequate provision of guidelines is needed and highly recommended to meet clients' needs and facilitate better outcomes. Objective: To understand clients' experiences of the recovery journey through the compensation system and to identify areas and strategies for quality improvement. Methods: A qualitative study of 23 participants with physical or mental disabilities caused by traffic accidents, which occurred, on average, 4 years ago. Purposive sampling of long-term recovery clients who made a compensation claim after their injuries was applied until data saturation was reached. Data were collected using semi-structured interviews and analysed through conventional thematic analysis. Results: This study demonstrated that recovery is a complex phenomenon that can be impacted by numerous challenges of navigating the compensation system and using its services. Clients perceived the compensation provider as limited in rules around which services they could access. A common perception amongst clients was that the compensation provider did not have the capacity and knowledge to understand health and recovery processes nor did it provide adequate guidelines or instructions that would assist clients with their recovery. Many clients dealt with numerous case managers and felt insufficiently informed on what to expect and do, which led to a lack of trust in rehabilitation management and case managers' decisions. According to clients, financial impacts were neglected and not addressed effectively. Many clients felt abandoned by the system which led to perceived feelings of desertion and negligence. Conclusion: Understanding modifiable barriers to recovery in compensation systems presents opportunities to amend current practices and consider a holistic, person-centred care approach. It is apparent that improved recovery management, communication and adequate provision of guidelines are needed to meet clients' needs and facilitate better outcomes. A person-centred care app...

IntroductionGlobally, road transport accidents contribute substantially to the number of deaths and also to the burden of disability. Up to 50 million people suffer a transport-related non-fatal injury each year, which often leads to long-term disability. It has been shown that substantial number of people with minor injuries struggle to recover and the reasons are still not well explored.Despite the high prevalence, little is known about the factors hindering recovery following minor traffic-related injuries. The aim of this paper is to present a protocol for the systematic review aiming to understand biopsychosocial factors related to non-recovery and identify current gaps in the literature.Methods and analysisThe review will be conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol guidelines. A search of the electronic databases, MEDLINE, EMBASE, Cochrane Central Register of Controlled trials, will be undertaken, in addition to Google Scholar and grey literature to identify studies in period from 2006 to 2016. Quantitative and qualitative research articles describing and identifying biopsychosocial factors associated with non-recovery and health outcomes such as pain, disability, functional recovery, health-related quality of life, post-traumatic stress disorder, depression, anxiety and return to work will be included. A conceptual framework developed to identify biopsychosocial factors will be applied to assure defined criterion.At present, there is little anticipation for meta-analyses due to the heterogeneity of factors and outcomes assessed. Therefore, a narrative synthesis based on study findings will be conducted.Ethics and disseminationEthical approval is not required as primary data will not be collected. Review results will be published as a part of thesis, peer-reviewed journal and conferences.Trialregistration numberPROSPEROregistration number: CRD42016052276.

Transport-related injuries are a leading cause of disability and mortality. The literature indicates that while some of these injuries are severe and catastrophic, most are classified as minor and moderate. In practice, it is expected that patients with minor and moderate injuries will recover with no serious consequences. However, recent research shows that, while half of patients recover relatively quickly, the other half experience long-term physical and mental health disabilities. The current study found multiple biopsychosocial factors impacting patients' outcomes. The use of the biopsychosocial conceptual framework, previous systematic review and qualitative study enabled assessment of specific biopsychosocial factors impacting recovery in patients claiming compensation for minor and moderate transport-related injuries. The identification of specific biopsychosocial factors identified as affecting recovery in this cohort will enable the development of a screening instrument to identify those of highest risk of poor recovery and to further develop strategies to facilitate enhanced outcomes. Objective: To investigate whether a range of previously identified biopsychosocial risk factors were associated with poorer health-related quality of life after transport-related injuries. Methods: This study involved 1,574 participants who sustained a transport-related injury, claimed compensation through the Victorian compensation scheme (in the Australian state of Victoria), and contributed to their cross-sectional outcome survey. Health-related quality of life was assessed using the EQ-5D-3L instrument. Results: Of the 1,574 participants (mean age 44.8 (standard deviation 16.6) years, 61% reported poor recovery expectations, 55% reported high pain intensity, 54% reported poor satisfaction with care provided, and 41% reported no improvement in their recovery. Poor quality of life was defined as EQ-5D-3L summary score 0-0.70. Predictors of selfreported poor health-related quality of life included older age (65+ years) patients (adjusted odds ratios (aOR) = 1.73, 95% confidence interval (95% CI) 1.04-2.87), higher pain intensity (aOR = 2.17, 95% CI 1.27-3.71), self-reported pre-injury chronic pain (aOR = 1.47, 95% CI 1.00-2.17), self-reported pre-injury mental health issues (aOR = 2.62, 95% CI 1.80-3.82), no improvement in recovery in the last 3 months (aOR = 1.54, 95% CI 1.15-2.06), longer hospital stay (>7 days) (aOR = 2.34, 95% CI 1.43-4.21) and no support from the family (aOR = 2.37, 95% CI 1.62-3.46). Conclusion: Biopsychosocial risk factors were associated with poorer health-related quality of life, regardless of the time since injury. Early assessment of these risk factors and tailored interventions will go some way towards improving outcomes among compensable patients with minor to moderate transport-related injuries.

IntroductionUnderstanding the impact of comorbidity on health outcomes is important given that comorbidities can affect survival, morbidity, service delivery costs and healthcare utilisation. However, little is known about the types of comorbidities affecting specific health outcomes after minor to moderate road trauma.MethodsThis study involved 1574 participants who claimed injury compensation following transport-related injury. Cross sectional data were collected. Health outcomes were assessed using the EQ-5D-3L specific domains and summary score. Twelve self-reported pre-existing chronic conditions were assessed using a multivariate logistic regression, adjusting for demographic and injury characteristics.ResultsOut of 1574 participants, only 17 (1%) participants reported no pre-existing comorbidities, 72% reported one, 13% reported two and 14% reported three or more comorbidities. Hypertension (15%), depression (14%) and anxiety (14%) were the most commonly reported comorbidities, followed by arthritis (13%), chronic pain (11%) and asthma (11%). Participants with a history of arthritis (adjusted odds ratio [AOR] 1.90, 95% CI 1.24 to 2.91); chronic back pain (AOR 1.59, 95% CI, 1.04 to 2.43); other chronic pain (AOR 2.73, 95% CI 1.42 to 4.24); depression (AOR 2.55, 95% CI 1.60 to 4.05) and anxiety (AOR 2.08, 95% CI 1.32 to 3.26) were at increased risk of poorer health outcomes, after controlling for age, gender, type of injury and time since injury.ConclusionThis study found that comorbidities such as arthritis, chronic back pain, other chronic pain, depression and anxiety significantly increase the odds of poorer health postinjury, regardless of the time since injury. Regular screening of comorbid conditions may help identify people likely to have poorer outcomes, thereby enabling the implementation of interventions to optimise health despite the presence of comorbidities.
