Quality of life following road traffic injury: A systematic literature review

Trajectories of health-related quality of life following road trauma: Latent growth mixture modeling across a 12-month cohort study

INTRODUCTION

Health-related quality of life (HRQoL) should be considered when evaluating the burden of road trauma (RT) injuries. This study aimed to identify distinct HRQoL trajectories following minor to severe RT injury and determine characteristics of trajectory membership.

METHODS

This prospective inception cohort study recruited 1480 RT survivors from three emergency departments in British Columbia, Canada (July 2018 - March 2020). HRQoL outcome was measured with the Short Form 12 survey (SF-12) and the 5-level version of the EuroQol instrument (EQ-5D-5L) at baseline (pre-injury) and at 2, 4, 6, and 12 months post-injury. Potential predictors of outcome trajectory included sociodemographic, psychological, medical, crash, and injury factors collected at baseline. We used a latent growth mixture model to identify distinct recovery trajectories and multinomial logistic regression to determine predictors of trajectory membership.

RESULTS

Three distinct HRQoL trajectories were identified for SF-12 subscales and EQ-5D-5L measures: Low/Moderate-Stable, High-Large decline, and High-Slight decline. Participants in the Low/Moderate-Stable trajectory had persistent low to moderate HRQoL before and after the injury. Those in the High-Large decline trajectory had good pre-injury HRQoL followed by persistently decreased HRQoL afterwards. The High-Slight decline trajectory was characterized by good pre-injury HRQoL and only a slight decline afterwards. Participants in the Low/Moderate-Stable and High-Large decline trajectories were considered at risk of permanently poor HRQoL following RT injury given their low HRQoL over a long period of time. Characteristics that placed participants in the Low/Moderate-Stable trajectory were older age, female gender, poor pre-injury health (medical comorbidity, prescribed medication use, complaints in the injured body area(s)), pre-injury somatic symptoms, pain catastrophizing or psychological distress, injury severity (ISS) and injury pain. Patients with head injury were less likely to be in the Low/Moderate-Stable trajectory. Risk factors for membership in the High-Large decline trajectory included older age (for physical HRQoL), younger age (for mental HRQoL), female gender, living alone, pre-injury psychological distress, ISS, injury pain, no expectations for a fast recovery, as well as head injuries, spine/back injuries or lower extremity injuries.

CONCLUSIONS

This study highlighted the heterogeneity of HRQoL trajectories following RT injury and the importance of considering differences between characteristics of survivors. In addition to injury type and severity, outcome is related to demographic factors, pre-injury health and pre-injury psychological factors.

Health-related quality of life in the year following road trauma: Longitudinal analysis using piecewise latent curve modeling

BACKGROUND

Road trauma (RT) survivors have reduced health-related quality of life (HRQoL). We identified phases and predictors of HRQoL change following RT injury.

METHODS

In a prospective cohort study of 1480 Canadian RT survivors aged 16 to 103 years (July 2018 - March 2020), physical component (PCS) and mental component (MCS) summary scores from the SF-12v2 were measured pre-injury and 2, 4, 6, and 12 months post-injury and their trajectories were analyzed with piecewise latent growth curve modeling. Potential predictors of HRQoL changes included sociodemographic, psychological, medical, and trauma-related factors.

RESULTS

PCS and MCS scores worsened from pre-injury to 2-months (phase 1) and then improved (phase 2), but never regained baseline values. Older age, somatic symptoms and pain catastrophizing were associated with lower preinjury PCS and MCS scores. Psychological distress was associated with lower preinjury MCS scores and higher preinjury PCS scores. Phase 1 PCS scores decreased most in females, participants with fewer pre-injury somatic symptoms and those without expectations for fast recovery. Phase 1 MCS decreases were associated with younger age, female sex, living alone, lower psychological distress, lack of expectation for fast recovery and higher injury pain. In phase 2, MCS improved most in participants not using recreational drugs; PCS improved most in participants with higher education and longer recovery expectations.

LIMITATIONS

There may be recall bias with reporting pre-injury HRQoL. Selection bias is possible.

CONCLUSIONS

Many factors influence HRQoL following RT. These findings may inform measures to minimize HRQoL reduction following RT and speed up subsequent recovery.

Safety and effectiveness of integrative Korean medicine for the management of patients sustaining injuries in traffic accidents during pregnancy: A retrospective chart review and questionnaire survey

The number of traffic accidents (TAs) is rising each year, and the severity of injuries can vary. Many people experience limitations in activities of daily living following TAs, affecting their quality of life. In pregnant women, even simple injuries caused by a TA could lead to unfavorable obstetric outcomes. Thus, we conducted a retrospective chart review and follow-up questionnaire survey to assess the safety and effectiveness of integrative Korean medicine (KM) treatment for pregnant women injured in TAs. To assess integrative KM effectiveness, the numeric rating scale (NRS) for TA-related symptoms, neck disability index (NDI) score, Oswestry disability index (ODI) score, shoulder pain and disability index score, Western Ontario and McMaster Universities Arthritis Index score, EuroQol 5-dimension 5-level (EQ-5D-5L) score, and patient global impression of change score were investigated for pregnant women injured in TAs. Additionally, for safety evaluation, obstetric and neonatal outcomes, as well as symptoms related to pregnancy, were assessed. At the end of treatment and follow-up, there were significant reductions in NDI and ODI scores, as well as NRS for neck pain, lower back pain, and headache, compared to scores at baseline. EQ-5D-5L scores significantly increased. A follow-up of 50 patients showed no major differences in obstetric and neonatal outcomes compared to the typical outcomes that occur in pregnant women and neonates. Major improvements were observed in the symptoms of patients who underwent integrative KM treatment after being injured in TAs. The symptoms occurred at a rate similar to those in typical pregnant women, while causality with integrative KM treatment was assessed to be unlikely or unclear. Therefore, integrative KM treatment may be considered an alternative treatment option for pregnant women who currently have limited treatment options.

Management of physical and psychological trauma resulting from motor vehicle crashes in Australian general practice: a mixed-methods approach

BACKGROUND

In Australia, motor vehicle crashes (MVC)-related health data are available from insurance claims and hospitals but not from primary care settings. This study aimed to identify the frequency of MVC-related consultations in Australian general practices, explore the pharmacological management of health conditions related to those crashes, and investigate general practitioners' (GPs) perceived barriers and enablers in managing these patients.

METHODS

Mixed-methods study. The quantitative component explored annual MVC-related consultation rates over seven years, the frequency of chronic pain, depression, anxiety or sleep issues after MVC, and management with opioids, antidepressants, anxiolytics or sedatives in a sample of 1,438,864 patients aged 16 + years attending 402 Australian general practices (MedicineInsight). Subsequently, we used content analysis of 81 GPs' qualitative responses to an online survey that included some of our quantitative findings to explore their experiences and attitudes to managing patients after MVC.

RESULTS

MVC-related consultation rates remained stable between 2012 and 2018 at around 9.0 per 10,000 consultations. In 2017/2018 compared to their peers, those experiencing a MVC had a higher frequency of chronic pain (48% vs. 26%), depression/anxiety (20% vs. 13%) and sleep issues (7% vs. 4%). In general, medications were prescribed more after MVC. Opioid prescribing was much higher among patients after MVC than their peers, whether they consulted for chronic pain (23.8% 95%CI 21.6;26.0 vs. 15.2%, 95%CI 14.5;15.8 in 2017/2018, respectively) or not (15.8%, 95%CI 13.9;17.6 vs. 6.7%, 95% CI 6.4;7.0 in 2017/2018). Qualitative analyses identified a lack of guidelines, local referral pathways and decision frameworks as critical barriers for GPs to manage patients after MVC. GPs also expressed interest in having better access to management tools for specific MVC-related consequences (e.g., whiplash/seatbelt injuries, acute/chronic pain management, mental health issues).

CONCLUSION

Chronic pain, mental health issues and the prescription of opioids were more frequent among patients experiencing MVC. This reinforces the relevance of appropriate management to limit the physical and psychological impact of MVC. GPs identified a lack of available resources (e.g. education, checklists and management support tools) for managing MVC-related consequences, and the need for local referral pathways and specific guidelines to escalate treatments.

Health-Related Quality of Life in severely injured patients in Finland: an observational cohort study of 325 patients with 1-year follow-up

BACKGROUND

Major trauma has a significant effect on Health-Related Quality of Life (HR-QoL). It is unclear, however, which factors most affect HR-QoL. This study aims to evaluate HR-QoL after severe injury in Finland and determine how different injury patterns and patient-related factors, such as level of education and socioeconomic group, are associated with HR-QoL. We also assess how well different injury scoring systems associate with HR-QoL.

METHODS

We retrospectively analyzed 325 severely injured trauma patients (aged ≥ 18 years, New Injury Severity Score, (NISS) ≥ 16, and alive at 1 year after injury) treated in the Intensive Care Unit (ICU) or High Dependence Unit (HDU) of Tampere University Hospital (TAUH) from 2013 through 2016. HR-QoL was assessed with the EQ-5D-3L questionnaire completed during ICU stay and 1 year after injury. HR-QOL index values and reported problems were further compared with Finnish population norms.

RESULTS

The severity of the injury (measured by ISS and NISS) had no significant association with the decrease in HR-QoL. Length of ICU stay had a weak negative correlation with post-injury HR-QoL and a weak positive correlation with the change in HR-QoL. The largest mean decrease in HR-QoL occurred in patients with spinal cord injury (Spine AIS ≥ 4) (-0.338 (SD 0.136)), spine injury in general (Spine AIS ≥ 2 (-0.201 (SD 0.279)), and a lower level of education (-0.157 (SD 0.231)). Patient's age, sex, or socioeconomic status did not seem to associate with smaller or greater changes in HR-QoL.

CONCLUSIONS

After serious injury, many patients have permanent disabilities which reduce HR-QoL. Injury scoring systems intended for assessing the risk for death did not seem to associate with HR-QoL and are not, therefore, a meaningful way to predict the future HR-QoL of a severely injured patient. Recovery from the injury seems to be weaker in poorer educated patients and patients with spinal cord injury, and these patients may benefit from targeted additional measures. Although there were significant differences in baseline HR-QoL levels between different socioeconomic groups, recovery from injury appears to be similar, which is likely due to equal access to high-quality trauma care.

Twelve-month recovery following road trauma: Results from an inception cohort in Vancouver, Canada

BACKGROUND

Injury-related disability following road trauma is a major public health concern. Unfortunately, outcome following road trauma and risk factors for poor recovery are inadequately studied, especially for road trauma survivors with minor injuries that do not require hospitalization.

OBJECTIVES

This manuscript reports 12-month recovery outcomes for a large cohort of road trauma survivors.

METHODS

This was a prospective, observational inception cohort study of 1,480 road trauma survivors recruited between July 2018 and March 2020 from 3 trauma centres in British Columbia, Canada. Participants were aged ≥16 years and arrived in a participating emergency department within 24 h of a motor vehicle collision. Data on baseline health and injury severity were collected from structured interviews and medical records. Outcome measures, including the SF-12, were collected during follow-up interviews at 2, 4, 6 and 12 months. Predictors of recovery outcomes were identified using Cox proportional hazards models and summarized using hazard ratios.

RESULTS

Only 42 % of participants self-reported full recovery and only 66 % reported a return to usual daily activities. Females, older individuals, pedestrians, and those who required hospital admission had a poorer recovery than other groups. Similar patterns were observed for the SF-12 physical component. For the SF-12 mental component, no significant differences were observed between participants admitted to hospital and those discharged home from the ED. Return to work was reported by 77 % of participants who had a paying job at baseline, with no significant differences between sex and age groups.

CONCLUSIONS

In a large cohort of road trauma survivors, under half self-reported full recovery one year after the injury. Poor mental health recovery was observed in both participants admitted to hospital and those discharged home from the ED. This finding may indicate a need for early intervention and continued mental health monitoring for all injured individuals, including for those with less serious injuries.

Ocular injuries associated with motor vehicle accidents: long term effects on quality of life

PURPOSE

To describe the prevalence and outcome of motor vehicle accidents-associated ocular injuries.

METHODS

A survey of patients who presented to the emergency room at a level 1 trauma center with motor vehicle accidents-associated ocular injuries. A patient questionnaire and review of clinical notes were conducted for all patients.

RESULTS

Of 274 motor vehicle accident victims with ocular injuries who presented to the emergency room, 40 (15%) responded to the survey. Over half of them were driving a vehicle, and most reported wearing a seat belt or a helmet. Most ocular injuries were mild. The most common injuries were bone fractures, subconjunctival hemorrhage, eyelid involvement and corneal injury. Most respondents had no change in vision and perceived their ocular involvement as a minor part of their injury. Most respondents returned to work and to driving within a year.

CONCLUSION

Our study sheds light on the details and extent of ocular involvement and the visual ability to perform daily activities following motor vehicle accidents.

Incidence of mental health conditions following pediatric hospital admissions: analysis of a national database

Introduction

Despite increasing survival of children following hospitalization, hospitalization may increase iatrogenic risk for mental health (MH) disorders, including acute stress, post-traumatic stress, anxiety, or depression. Using a population-based retrospective cohort study, we assessed the rates of new MH diagnoses during the 12 months after hospitalization, including the moderating effects of ICU exposure.

Study design/methods

This was a retrospective case control study using the Truven Health Analytics insurance database. Inclusion criteria included children aged 3-21 years, insurance enrollment for >12 months before and after hospital admission. We excluded children with hospitalization 2 years prior to index hospitalization and those with prior MH diagnoses. We extracted admission type, ICD-10 codes, demographic, clinical, and service coordination variables from the database. We established age- and sex-matched cohorts of non-hospitalized children. The primary outcome was a new MH diagnosis. Multivariable regression methods examined the risk of incident MH disorder(s) between hospitalized and non-hospitalized children. Among hospitalized children, we further assessed effect modification from ICU (vs. non-ICU) stay, admission year, length of stay, medical complexity, and geographic region.

Results

New MH diagnoses occurred among 19,418 (7%) hospitalized children, 3,336 (8%) ICU-hospitalized children and 28,209 (5%) matched healthy controls. The most common MH diagnoses were anxiety (2.5%), depression (1.9%), and stress/trauma (2.2%) disorders. Hospitalization increased the odds of new MH diagnoses by 12.3% (OR: 1.123, 95% CI: 1.079-1.17) and ICU-hospitalization increased these odds by 63% (OR: 1.63, 95% CI: 1.483-1.79) as compared to matched, non-hospitalized children. Children with non-complex chronic diseases (OR: 2.91, 95% CI: 2.84-2.977) and complex chronic diseases (OR: 5.16, 95% CI: 5.032-5.289) had a substantially higher risk for new MH diagnoses after hospitalization compared to patients with acute illnesses.

Conclusion

Pediatric hospitalization is associated with higher, long-term risk of new mental health diagnoses, and ICU hospitalization further increases that risk within 12 months of the acute episode. Acute care hospitalization confers iatrogenic risks that warrant long-term mental and behavioral health follow-up.

The importance of self-regulation and mental health for effective recovery after traffic injuries: A comprehensive network analysis approach

OBJECTIVE

Traffic injuries significantly impact people's psychological, physical and social wellbeing, and involve complex self-regulation responses. Psychological impacts are seldom recognized and addressed holistically. This study employs network analysis to investigate the interconnectedness between different dimensions that influence mental health vulnerability and recovery after traffic injuries.

METHODS

120 adults with mild-to-moderate traffic injuries and 112 non-injured controls were recruited. The network investigation employed two main approaches. Four cross-sectional networks examined the interrelationships between self-regulation responses (cognitive and autonomic) and various health dimensions (psychological, physical, social) over time (1, 3, 6, 12 months). Three predictive networks explored influences of acute self-regulation responses (1 month) on long-term outcomes. Network analyses focused on between-group differences in overall connectivity and centrality measures (nodal strength).

RESULTS

An overall measure of psychological wellbeing consistently emerged as the most central (strongest) node in both groups' networks. Injured individuals showed higher overall connectivity and differences in the centrality of self-regulation nodes compared to controls, at 1-month and 12-months post-injury. These patterns were similarly observed in the predictive networks, including differences in cognitive and autonomic self-regulation influences.

CONCLUSIONS

Network analyses highlighted the crucial role of psychological health and self-regulation, in promoting optimal wellbeing and effective recovery. Post-traffic injury, increased connectivity indicated prolonged vulnerability for at least a year, underscoring the need of ongoing support beyond the initial improvements. A comprehensive approach that prioritizes psychological health and self-regulation through psychologically informed services, early psychological screening, and interventions promoting cognitive and autonomic self-regulation is crucial for mitigating morbidity and facilitating recovery.

Prevalence and levels of disability post road traffic orthopaedic injuries in Rwanda

Background

Prolonged disability resulting from road traffic injuries (RTIs) contributes significantly to morbidity and disease burden. A good understanding of the prevalence and the level of disability of orthopaedic injuries in developing countries is crucial for improvement; however, such data are currently lacking in Rwanda.

Objectives

To determine the prevalence and levels of disability of 2 years post-road traffic orthopaedic injuries in Rwanda.

Method

A multicentre, cross-sectional study from five Rwandan referral hospitals of 368 adult RTI victims' sustained from accidents in 2019. Between 02 June 2022, and 31 August 2022, two years after the injury, participants completed the World Health Organization Disability Assessment Schedule (WHODAS 2.0) Questionnaire for the degree of impairment and the Upper Extremity Functional Scale and Lower-Extremity Functional Scale forms for limb functional evaluation. Descriptive, inferential statistics Chi-square and multinomial regression models were analysed using R Studio.

Results

The study's mean age of the RTOI victims was 37.5 (±11.26) years, with a sex ratio M: F:3: 1. The prevalence of disability following road traffic orthopedic injury (RTOI) after 2 years was 36.14%, with victims having WHODAS score > 25.0% and 36.31% were still unable to return to their usual activities. Age group, Severe Kampala Trauma Score and lack of rehabilitation contributed to disability. The most affected WHODAS domains were participation in society (33%) and life activities (28%).

Conclusion

The prevalence and levels of disability because of RTOI in Rwanda are high, with mobility and participation in life being more affected than other WHODAS domains. Middle-aged and socio-economically underprivileged persons are the most affected.

Contribution

This study showed that a good rehabilitation approach and economic support for the RTI victims would decrease their disabilities in Rwanda.

Traffic safety and public health in China - Past knowledge, current status, and future directions

Transportation-related harms have developed into a social disease, threatening public safety and health in China. We aimed to increase the global understanding of traffic safety and public health in China from past knowledge, current status, and future directions by collecting, collating, and analyzing the Chinese traffic incidents reported in the published literature. A systematic search of China National Knowledge Infrastructure, Weipu, and published articles referenced in PubMed, Web of Science and ProQuest between January 1, 1988 and April 30, 2023 was performed. China encountered the first recorded traffic accident as early as three thousand years ago in the Shang Dynasty. An increase in vehicle capacity and velocity increased the traffic risks during the transition from rickshaws and livestock to motor vehicles in varying traffic environments. Humans are not only the decisive factor of a large number of vehicles, traffic routes, and environmental variables, but also the victims at the end and starting point of traffic accidents. Injuries (mechanical force, burns) and diseases (traffic-related air pollution, noise) caused by traffic activities not only threaten public health, but also cause risks to safe driving. Analysis of traffic activities and biomarkers promotes the treatment of traffic injuries in ethology and medicine. China prepared for the construction of healthy transportation in the "decade of road safety" toward an estimation of worldwide road traffic injuries in 2030. Improvement of traffic safety concerning public health under the "Outline of the National Comprehensive Three-dimensional Transportation Network Planning" in China will propel the realization of worldwide traffic environmental advancement.

"I knew who I was this morning, but I've changed a few times since then": A study combining register and self-reported QoL data in assessing how response shift may occur in an injury population

AIMS

The phenomenon of response shift may occur when people are exposed to a traumatic event and reevaluate the meaning of important aspects of their lives; a phenomenon that a traditional pre- and post-assessment cannot catch. Hence, the aim of the study was to increase the knowledge of how response shift may occur in people who have suffered an injury.

METHODS

The current study is a register-based cohort study including 2512 participants. Data were retrieved from the Swedish LifeGene project and an online questionnaire, including the EQ5D. In order to analyze how response shift may occur, a "Then-test" and Structural Equation Model (SEM) were used.

RESULTS

The results showed a clear indication of response shift through recalibration. The SEM analysis confirmed that participants significantly shifted their response between the post- and retrospective measurements. Significant differences were found for the VAS and for two of the five EQ5D dimensions: anxiety/depression and pain.

CONCLUSION

This study provides additional knowledge to how response shift can occur in an injury population. This information can guide the next generation of QoL measures and be used as guidance for designing interventions for those suffering injuries. Furthermore, it may have an impact on how to interpret evaluations of interventions.

A global measure of patient-reported outcomes after injury - life back on track

PURPOSE

Assess the psychometric properties of the Life Back on Track (LBoT) measure, a novel self-reported single-item global measure of the trajectory of wellbeing after a transport accident.

MATERIALS AND METHODS

Evaluated the validity, reliability, sensitivity, and responsiveness using four survey waves (n = 1556 in wave 1), and two repeated cross-sectional surveys (n = 5238) and (n = 1964), of individuals injured in a transport accident in Victoria.

RESULTS

There were statistically significant differences in the distribution of the LBoT scores by the respondent depression or pain scores, return to work status, financial ability to get by, ability to cope, and ability to bounce back (all p < 0.001). The LBoT measure was a statistically significant (p < 0.001) and reasonable predictor of future work status, and was moderately correlated (>0.67) with the EQ-5D-3L (concurrent validity). Retest reliability (ICC ≥0.76) and sensitivity (effect sizes >1.52) were supported, and it was moderately responsive to change (standard response mean statistics 0.4-0.8).

CONCLUSIONS

LBoT is a valid measure to track the individual's trajectory of subjective wellbeing in the context of recovery after a trauma, and is potentially useful as an indicator to track the performance of commissioned providers, and to monitor or evaluate the value of service outcomes.Implications for RehabilitationThere is a demand to develop a simple metric to measure the impact of injury, the effectiveness of rehabilitation and the degree of recovery from trauma.Life Back on Track (LBoT) is a valid single-item measure to track an individual's trajectory of subjective wellbeing after trauma.It has the potential to complement clinical measures where a routine collection of a simple measure is desirable.It is suitable as an indicator of service outcomes for organisations that commission services.

Perceived neighborhood environment walkability and health-related quality of life among predominantly Black and Latino adults in New York City

BACKGROUND

Measures of the built environment such as neighborhood walkability have been associated with health behaviors such as physical activity, the lack of which in turn may contribute to the development of diseases such as obesity, diabetes, cardiovascular disease, and cancer. However, limited research has examined these measures in association with health-related quality of life (HR-QoL), particularly in minoritized populations. We examined the relationship between perceived neighborhood environment and HR-QoL in a sample of mostly Black and Latino residents in New York City (NYC).

METHODS

This study utilized the baseline survey data from the Physical Activity and Redesigned Community Spaces (PARCS) Study among 1252 residents [34.6% Black, 54.1% Latino, 80.1% female, mean(±SD) age = 38.8 ± 12.5) in 54 park neighborhoods in NYC. Perceived built environment was measured using Neighborhood Environment and Walkability Survey, and mental and physical HR-QoL was estimated using Short Form (SF)-12. Using factor analysis, we identified two subscales of neighborhood walkability: enablers (e.g., trails, sidewalks, esthetics) vs. barriers (e.g., high crime and traffic). In addition, we included a third subscale on neighborhood satisfaction. Generalized Estimating Equation models adjusted for demographics and BMI and accounted for the clustering effect within neighborhood. Multiple imputation was used to account for missing data.

RESULTS

Mental HR-QoL was associated with barriers of walkability (β ± SE = - 1.63 ± 0.55, p < 0.01) and neighborhood satisfaction (β ± SE = 1.55 ± 0.66, p = 0.02), after adjusting for covariates. Physical HR-QoL was associated with only barriers of walkability (β ± SE = - 1.13 ± 0.57, p < 0.05).

CONCLUSIONS

Among NYC residents living in minoritized neighborhoods, mitigating negative aspects of the neighborhood environment may be more crucial than adding positive features in terms of HR-QoL. Our study points to the need to investigate further the role of the built environment in urban, minoritized communities.

A proof-of-concept randomized controlled trial of follow-up mental health care for traumatic injury patients following hospital discharge

INTRODUCTION

Traumatic injuries account for a huge burden of disease. Many patients develop persistent mental health problems in the months following hospital discharge. This proof-of-concept trial investigated whether Stepped Care comprising follow-up assessment telephone calls and appropriate referral information would lead to better mental health and functioning in traumatic injury patients.

METHODS

Patients admitted to the Trauma Service at Royal North Shore Hospital were randomized to either Stepped Care (n = 84) or Treatment as Usual (n = 90). All patients were assessed for anxiety, depression, and posttraumatic stress prior to hospital discharge. Those in Stepped Care received a telephone call at 1-month and 3-months after hospital discharge in which they were administered a brief assessment; patients who reported mental health or pain difficulties were provided with information for local specialists to address their specific problem. All patients were independently assessed by telephone interview 9- months after hospital discharge for posttraumatic stress disorder (PTSD) (primary outcome), as well as for anxiety, depression, disability, and pain.

RESULTS

There were 58 (73%) patients that could be contacted at either the 1-month or 3-month assessments. Of those contacted, 28 patients (48% of those contacted) were referred for specialist assistance. There were no differences between treatment arms on PTSD symptoms at follow-up [F_1,95 = 0.55, p = 0.46]. At the 9-month assessment, patients in the Stepped Care condition reported significantly less anxiety [F_1,95 = 5.07, p = 0.03] and disability [F_1,95 = 4.37, p = 0.04] relative to those in Treatment as Usual. At 9 months there was no difference between conditions on depression [F_1,95 = 1.03, p = 0.31]. There were no differences between conditions on self-reported pain difficulties.

CONCLUSIONS

This proof-of-concept trial suggests that brief screening assessments of traumatic injury patients following hospital discharge, combined with appropriate referral information, may lead to better functional outcomes. Further research is needed with larger sample sizes and greater verification of referral uptake to validate this finding.

Global, Regional, and National Burden of Road Injuries from 1990 to 2019

(1) Background: Understanding occurrence can help formulate effective preventative laws and regulations. However, the most recent global burden and road injuries (RIs) trends have not been reported. This study reports the burden of RIs globally from 1990 to 2019. (2) Methods: RIs data were downloaded from the Global Burden of Disease 2019. Incidence, deaths, and disability-adjusted life years (DALYs) described the trend and burden of RIs. We calculated age-standardized rates (ASRs) and estimated annual percentage change (EAPC) for the above indexes to evaluate the temporal trend of RIs. We evaluated the social-demographic index (SDI) with epidemiological RI parameters and reported proportions of age-standardized rates due to RI. (3) Results: In 2019, the global incidence of RIs reached 103.2 million. The EAPC of RI incidence increased, whereas deaths and DALYs decreased. Age-standardized incident rate (ASIR) was highest in low-middle SDI regions, age-standardized death rate (ASDR) was high in middle SDI regions, and age-standardized DALYs increased in low SDI regions. The highest accident rates were found in those aged 20-24 years old. Cyclist injuries were the leading RIs (34%), though pedestrian and motor vehicle accidents were the leading cause of death (37.4%, 37.6%) and DALYs (35.7%, 32.3%), respectively. (4) Conclusions: Over the past 30 years, RIs incidence increased annually, though death and DALY rates decreased. RIs places a considerable burden on public health in low SDI countries. Data should be used to develop and implement effective measures to reduce the burden of RIs.

Pain and mental health symptom patterns and treatment trajectories following road trauma: a registry-based cohort study

PURPOSE

This study aimed to characterise recovery from pain and mental health symptoms, and identify whether treatment use facilitates recovery.

METHODS

Victorian State Trauma Registry and Victorian Orthopaedic Trauma Outcomes Registry participants without neurotrauma who had transport injury claims with the Transport Accident Commission from 2007 to 2014 were included (n = 5908). Latent transition analysis of pain Numeric Rating Scale, SF-12, and EQ-5D-3L pain and mental health items from 6 to 12 months, and 12 to 24 months post-injury were used to identify symptom transitions.

RESULTS

Four transition groups were identified: transition to low problems by 12-months; transition to low problems at 24-months; stable low problems; and no transition from problems. Group-based trajectory modelling of pain and mental health treatments found three treatment trajectories: low/no treatment, a moderate treatment that declined to low treatment 3-12 months post-injury, and increasing treatment over time. Predictors of pain and mental health recovery transitions, identified using multinomial logistic regression, were primarily found to be non-modifiable socioeconomic and health-related characteristics (e.g., higher education, working pre-injury, and not having comorbidities), and low treatment trajectories.

CONCLUSIONS

Targeted and collaborative rehabilitation should be considered for people at risk of persistent pain or mental health symptoms to optimise their recovery, particularly patients with socioeconomic disadvantage.IMPLICATIONS FOR REHABILITATIONTwo-thirds of people experience pain and/or mental health within the first 24-months after hospitalization for road trauma, of whom only 6-7% recover by 12-months, and a further 6% recover by 24-months post-injury.There were three main trajectories of administrative records of treatments received in the first two years after injury: 76 and 83% had low treatment, 18 and 12% had moderate then declining treatment levels, and 6 and 5% had stable high treatment for pain or mental health, respectively.People who recovered from pain or mental health symptoms generally had lower treatment and higher socioeconomic position, highlighting that coordinated rehabilitation care should be prioritized for people living with socioeconomic disadvantage.

'Coming home does not mean that the injury has gone'-exploring the lived experience of socioeconomic and quality of life outcomes in post-discharge trauma patients in urban India

Trauma results in long-term socioeconomic outcomes that affect quality of life (QOL) after discharge. However, there is limited research on the lived experience of these outcomes and QOL from low - and middle-income countries. The aim of this study was to explore the different socioeconomic and QOL outcomes that trauma patients have experienced during their recovery. We conducted semi-structured qualitative interviews of 21 adult trauma patients between three to eight months after discharge from two tertiary-care public hospitals in Mumbai, India. We performed thematic analysis to identify emerging themes within the range of different experiences of the participants across gender, age, and mechanism of injury. Three themes emerged in the analysis. Recovery is incomplete-even up to eight months post discharge, participants had needs unmet by the healthcare system. Recovery is expensive-participants struggled with a range of direct and indirect costs and had to adopt coping strategies. Recovery is intersocial-post-discharge socioeconomic and QOL outcomes of the participants were shaped by the nature of social support available and their sociodemographic characteristics. Provisioning affordable and accessible rehabilitation services, and linkages with support groups may improve these outcomes. Future research should look at the effect of age and gender on these outcomes.

Biopsychosocial sequelae of chronically painful injuries sustained in motor vehicle accidents contributing to non-recovery: A retrospective cohort study

BACKGROUND

Claimants with chronically painful injuries sustained in motor vehicle accidents (MVAs) undergo assessment and management influenced by insurance and medico-legal processes defined by a biomedical paradigm which is discordant with best evidence. We aim to demonstrate the impact of biopsychosocial factors on post-MVA sequelae which contribute to non-recovery.

METHODS

This was a retrospective cohort study of medico-legal documents and reports on 300 consecutive claimants referred to a pain medicine physician over 7 years (2012-2018) for assessment of painful musculoskeletal injuries post-MVA. One hundred data items were extracted from the medico-legal documents and reports for each claimant and entered into an electronic database. Post-MVA sequelae were analysed using chi-square analysis (OR >2) for significant associations with demographic, pre-MVA and post-MVA variables. Factors with significant associations were entered into a logistic regression model to determine significant statistical predictors of post-MVA sequelae contributing to non-recovery.

RESULTS

The claimants were aged 17 to 80 years (mean age 42 years), and approximately half (53%, n=159) were female. The time from MVA to interview averaged 2.5 years. Widespread pain was present in 18% (n=54), and widespread somatosensory signs implying central sensitisation (OR=9.85, p<.001) was the most significant multivariate association. Long-term opiate use post-MVA (32%) was predicted by pre-MVA sleep disturbance (OR=5.08, p=.001), post-MVA major depressive disorder (MDD) (OR=3.02, p=.003) and long-term unemployment (OR=2.22. p=.007). Approximately half (47%, n=142) required post-MVA support from a psychologist or psychiatrist. Post-traumatic stress disorder (PTSD) was diagnosed by a psychiatrist or psychologist in 20% (n=59), yet early identification of risk of PTSD was rare. Pre-MVA, 89.4% (n=268) were studying or employed. Permanent unemployability post-MVA occurred in 35% (n=104) and was predicted by MDD (OR=3.59, p=.001) and antidepressant use (OR=2.17, p=.005). Major social change post-MVA (70%) was predicted by older age (OR=.966, p=.003), depressive symptoms (OR=3.71, p<.001) and opiate use (OR=2.00, p=.039).

CONCLUSIONS

Biomedical factors, including older age, impaired sleep and indicators of widespread central sensitisation, and psychological factors, including stress, anxiety and depression, were the most prominent multivariate associations as statistical predictors of major adverse sequelae contributing to non-recovery for claimants with chronic pain post-MVA.

Factors impacting trauma-specific quality of life following injury: A multi-center assessment in Lebanon

OBJECTIVE

Injuries account for a large portion of the global burden of disease, representing over 10% of all disability adjusted life years (DALYs). This study analyzes the economic impact of injury for those experiencing moderate-to-severe injury in Beirut, Lebanon. It further examines the impact of different demographic and socioeconomic factors on trauma-specific quality of life 1-2 years following injury.

METHODS

This was a prospective cohort study following patients 1-2 years after being treated for injury at one of three hospitals in Beirut, Lebanon. Patients interviewed by phone. In addition to questions on financial impact, access to healthcare, and socioeconomic status, the Trauma-specific Quality of Life (TQoL) Questionnaire was used to assess quality of life following injury. Multivariable linear models were constructed to examine TQoL and demographics among institutes.

RESULTS

116 patients completed interviews. The average out-of-pocket cost of injury was 2975.42 USD, 65% of which was borrowed. 21% of people lost employment due to injury. Patients at Geitawi Hospital and the Rafic Hariri Governmental Hospital borrowed more on average and had higher reductions in employment than patients at the American University of Beirut Medical Center (AUBMC). There was a loss of income for those employed at the time of injury, with a mean monthly loss of 261.6 USD. The economic impact of injury was 10,329.00 USD. 25% of patients reported difficulty with accessing follow-up care, predominantly due to cost. Mean-adjusted Trauma-specific Quality of life (TQoL) was highest at AUBMC. Education was associated with functional recovery in the TQoL questionnaire; for every additional year of education there was an increase in the functional recovery domain of 0.03.

CONCLUSION

Individuals that experienced moderate-to-severe injury in Beirut, Lebanon, suffered financial repercussions, including reductions in income, less employment, or unemployment. Across all patients surveyed, higher level of education was associated with better functional quality of life. More study into the intricacies of accessing healthcare care in Lebanon, especially given the current economic and political climate, are crucial to maintain the health of those experiencing injury and can help inform targeted interventions.

Factors associated with long term work incapacity following a non-catastrophic road traffic injury: analysis of a two-year prospective cohort study

Background

Road traffic injuries (RTIs), primarily musculoskeletal in nature, are the leading cause of unintentional injury worldwide, incurring significant individual and societal burden. Investigation of a large representative cohort is needed to validate early identifiable predictors of long-term work incapacity post-RTI. Therefore, up until two years post-RTI we aimed to: evaluate absolute occurrence of return-to-work (RTW) and occurrence by injury compensation claimant status; evaluate early factors (e.g., biopsychosocial and injury-related) that influence RTW longitudinally; and identify factors potentially modifiable with intervention (e.g., psychological distress and pain).

Methods

Prospective cohort study of 2019 adult participants, recruited within 28 days of a non-catastrophic RTI, predominantly of mild-to-moderate severity, in New South Wales, Australia. Biopsychosocial, injury, and compensation data were collected via telephone interview within one-month of injury (baseline). Work status was self-reported at baseline, 6-, 12-, and 24-months. Analyses were restricted to participants who reported paid work pre-injury (N = 1533). Type-3 global p-values were used to evaluate explanatory factors for returning to ‘any’ or ‘full duties’ paid work across factor subcategories. Modified Poisson regression modelling was used to evaluate factors associated with RTW with adjustment for potential covariates.

Results

Only ~ 30% of people with RTI returned to full work duties within one-month post-injury, but the majority (76.7%) resumed full duties by 6-months. A significant portion of participants were working with modified duties (~ 10%) or not working at all (~ 10%) at 6-, 12-, and 24-months. Female sex, low education, low income, physically demanding occupations, pre-injury comorbidities, and high injury severity were negatively associated with RTW. Claiming injury compensation in the fault-based scheme operating at the time, and early identified post-injury pain and psychological distress, were key factors negatively associated with RTW up until two years post-injury.

Conclusions

Long-term work incapacity was observed in 20% of people following RTI. Our findings have implications that suggest review of the design of injury compensation schemes and processes, early identification of those at risk of delayed RTW using validated pain and psychological health assessment tools, and improved interventions to address risks, may facilitate sustainable RTW.

Measuring socioeconomic outcomes in trauma patients up to one year post-discharge: A systematic review and meta-analysis

INTRODUCTION

Trauma accounts for nearly one-tenth of the global disability-adjusted life-years, a large proportion of which is seen in low- and middle-income countries (LMICs). Trauma can affect employment opportunities, reduce social participation, be influenced by social support, and significantly reduce the quality of life (QOL) among survivors. Research typically focuses on specific trauma sub-groups. This dispersed knowledge results in limited understanding of these outcomes in trauma patients as a whole across different populations and settings. We aimed to assess and provide a systematic overview of current knowledge about return-to-work (RTW), participation, social support, and QOL in trauma patients up to one year after discharge.

METHODS

We undertook a systematic review of the literature published since 2010 on RTW, participation, social support, and QOL in adult trauma populations, up to one year from discharge, utilizing the most commonly used measurement tools from three databases: MEDLINE, EMBASE, and the Cochrane Library. We performed a meta-analysis based on the type of outcome, tool for measurement, and the specific effect measure as well as assessed the methodological quality of the included studies.

RESULTS

A total of 43 articles were included. More than one-third (36%) of patients had not returned to work even a year after discharge. Those who did return to work took more than 3 months to do so. Trauma patients reported receiving moderate social support. There were no studies reporting social participation among trauma patients using the inclusion criteria. The QOL scores of the trauma patients did not reach the population norms or pre-injury levels even a year after discharge. Older adults and females tended to have poorer outcomes. Elderly individuals and females were under-represented in the studies. More than three-quarters of the included studies were from high-income countries (HICs) and had higher methodological quality.

CONCLUSION

RTW and QOL are affected by trauma even a year after discharge and the social support received was moderate, especially among elderly and female patients. Future studies should move towards building more high-quality evidence from LMICs on long-term socioeconomic outcomes including social support, participation and unpaid work.

Tendência da taxa de mortalidade por acidentes de trânsito entre motociclistas no estado de São Paulo, Brasil, de 2015 a 2020

RESUMO Objetivo: Avaliar a tendência da taxa de mortalidade de motociclistas decorrentes de lesões por acidentes de trânsito no estado de São Paulo, Brasil, nos anos de 2015 a 2020. Métodos: Estudo ecológico de delineamento de série temporal com dados secundários provenientes do Sistema de Informações Gerenciais de Acidentes de Trânsito do Estado de São Paulo (INFOSIGA), referentes aos óbitos de motociclistas decorrentes de lesões por acidentes de trânsito no estado de São Paulo, de 2015 a 2020. A variação percentual anual foi calculada pelo modelo de regressão de Prais-Winsten, utilizando o programa STATA 14.0.

A maior proporção de óbitos ocorreu entre indivíduos do sexo masculino (88,1%), entre 18 e 24 anos de idade (27,9%), nas duas regiões mais populosas e urbanizadas do estado. A distribuição da taxa de mortalidade apresentou mínima variação no período analisado, de 4,22 a 4,42 óbitos/100 mil habitantes. Entre as variáveis sociodemográficas analisadas, a tendência da mortalidade de motociclistas foi estacionária em sua maioria. Conclusão: A análise da taxa de mortalidade de motociclistas decorrentes de lesões por acidentes de trânsito no estado de São Paulo apresentou tendência estacionária.

The economic burden of road traffic injuries until one-year after hospitalization: A survey study

OBJECTIVE

Road Traffic Injuries (RTIs) are one of the most crucial and challenging public health problems in low and middle income countries. Despite continuous efforts to estimate both personal and societal costs of RTIs however, their long-term effects have remained marginal. The current study aimed to explore the economic burden of RTIs until one year after the victim's hospitalization.

METHODS

The study included a total of 1150 RTI victims, who were admitted to two trauma-referral hospitals during 2016. Data on direct medical costs, direct non-medical costs and indirect costs were gathered for each study sample via hospital records and phone surveys. Direct and indirect costs from a social perspective were estimated based on Micro Costing Approach followed by the Human Capital Approach. Also, the explanatory variables affecting the costs of RTIs were identified using the liner regression model.

RESULTS

The average amounts of direct (medical, non-medical), indirect, and total costs of RTI were estimated as 2,908 US$ (1,591 US$, 1,316 US$), 5,790 US$, and 8,701 US$ respectively. Also, several variables were significantly affecting the costs of RTIs including age, marital status, employment status, severity of injury, receiving physiotherapy care, victim's vehicle type in crash, crash time and location.

CONCLUSIONS

Findings suggest that RTIs are considered as an enormous burden on Iranian GDP per capita and health expenditure per capita occupying 167% and 347% respectively. This enormous economic burden caused by RTIs requires more policy regulations and prevention programs to decrease RTIs.

Driver, Collision and Meteorological Characteristics of Motor Vehicle Collisions among Road Trauma Survivors

Road trauma remains a significant public health problem. We aimed to identify sub-groups of motor vehicle collisions in Victoria, Australia, and the association between collision characteristics and outcomes up to 24 months post-injury. Data were extracted from the Victorian State Trauma Registry for injured drivers aged ≥16 years, from 2010 to 2016, with a compensation claim who survived ≥12 months post-injury. People with intentional or severe head injury were excluded, resulting in 2735 cases. Latent class analysis was used to identify collision classes for driver fault and blood alcohol concentration (BAC), day and time of collision, weather conditions, single vs. multi-vehicle and regional vs. metropolitan injury location. Five classes were identified: (1) daytime multi-vehicle collisions, no other at fault; (2) daytime single-vehicle predominantly weekday collisions; (3) evening single-vehicle collisions, no other at fault, 36% with BAC ≥ 0.05; (4) sunrise or sunset weekday collisions; and (5) dusk and evening multi-vehicle in metropolitan areas with BAC < 0.05. Mixed linear and logistic regression analyses examined associations between collision class and return to work, health (EQ-5D-3L summary score) and independent function Glasgow Outcome Scale - Extended at 6, 12 and 24 months. After adjusting for demographic, health and injury characteristics, collision class was not associated with outcomes. Rather, risk of poor outcomes was associated with age, sex and socioeconomic disadvantage, education, pre-injury health and injury severity. People at risk of poor recovery may be identified from factors available during the hospital admission and may benefit from clinical assessment and targeted referrals and treatments.

Quality of Life after Motorcycle Traffic Injuries: A Cohort Study in Northwest of Iran

Objective:

To investigate the quality of life (QOL) of injured motorcyclists and associated factors in a period of three months after the accident.

Methods:

In the present study, we were included 190 injured motorcyclists who admitted to two referral specialized hospitals (Emam Reza and Shohada) in Tabriz, between June 2018 and January 2019. All injured motorcyclists were contacted through the telephone one and 171 of them (90%) three months after their accident to complete an EQ-5D-3L questionnaire. The baseline measurements were gathered by using face to face interviews in the hospitals. The QOL score could vary between 1 and 3. The higher score showed a lower QOL.

Results:

The injured motorcyclist’s QOL score was relatively better in three months after the accident (mean±Standard Deviation (SD): 1.78±0.51) in comparison with their status a month after the accident (2.15±0.65) (p<0.001). The multivariable model showed that individuals with pelvis injuries (Coef: 0.29, (95% CI: 0.16, 0.42), p=0.001) and knee injuries (Coef: 0.26, (95% CI: 0.10, 0.42), p=0.001), experienced a higher QOL score. Also, those whose accident had happened in rainy weather experienced higher QOL score (Coef: 0.33, (95% CI: 0.12, 0.53), p=0.001). The patients who were in an accident with a vehicle were experienced a better QOL than others (Coef: -0.26, (95% CI: -0.43, -0.09), p=0.002).

Conclusion:

The assessment of three-months post-accident showed that the QOL score of the motorcyclists was reduced. It is recommended that the QOL of patients should be improved in hospital discharge victims.

Nanodelivery of oxiracetam enhances memory, functional recovery and induces neuroprotection following concussive head injury

Military personnel are the most susceptible to concussive head injury (CHI) caused by explosion, blast or missile or blunt head trauma. Mild to moderate CHI could induce lifetime functional and cognitive disturbances causing significant decrease in quality of life. Severe CHI leads to instant death and lifetime paralysis. Thus, further exploration of novel therapeutic agents or new features of known pharmacological agents are needed to enhance quality of life of CHI victims. Previous reports from our laboratory showed that mild CHI induced by weight drop technique causing an impact of 0.224N results in profound progressive functional deficit, memory impairment and brain pathology from 5h after trauma that continued over several weeks of injury. In this investigation we report that TiO2 nanowired delivery of oxiracetam (50mg/kg, i.p.) daily for 5 days after CHI resulted in significant improvement of functional deficit on the 8th day. This was observed using Rota Rod treadmill, memory improvement assessed by the time spent in finding hidden platform under water. The motor function improvement is seen in oxiracetam treated CHI group by placing forepaw on an inclined mesh walking and foot print analysis for stride length and distance between hind feet. TiO2-nanowired oxiracetam also induced marked improvements in the cerebral blood flow, reduction in the BBB breakdown and edema formation as well as neuroprotection of neuronal, glial and myelin damages caused by CHI at light and electron microscopy on the 7th day after 5 days TiO2 oxiracetam treatment. Adverse biochemical events such as upregulation of CSF nitrite and nitrate, IL-6, TNF-a and p-Tau are also reduced significantly in oxiracetam treated CHI group. On the other hand post treatment of 100mg/kg dose of normal oxiracetam in identical conditions after CHI is needed to show slight but significant neuroprotection together with mild recovery of memory function and functional deficits on the 8th day. These observations are the first to point out that nanowired delivery of oxiracetam has superior neuroprotective ability in CHI. These results indicate a promising clinical future of TiO2 oxiracetam in treating CHI patients for better quality of life and neurorehabilitation, not reported earlier.

Measuring post-discharge socioeconomic and quality of life outcomes in trauma patients: a scoping review

Purpose

Trauma is a global public health challenge. Measuring post-discharge socioeconomic and quality-of-life outcomes can help better understand and reduce the consequences of trauma.

Methods

We performed a scoping review to map the existing research on post-discharge outcomes for trauma patients, irrespective of the country or setting in which the study was performed. The scoping review was conducted by searching six databases – MEDLINE, EMBASE, the Cochrane Library, Global Index Medicus, BASE, and Web of Science – to identify all articles that report post-discharge socioeconomic or quality of life outcomes in trauma patients from 2009 to 2018.

Results

Seven hundred fifty-eight articles were included in this study, extracting 958 outcomes. Most studies (82%) were from high-income countries (HICs). More studies from low- and middle-income countries (LMICs) were cross-sectional (71%) compared with HIC settings (46%). There was a wide variety of different definitions, interpretations, and measurements used by various articles for similar outcomes. Quality of life, return to work, social support, cost, and participation were the main outcomes studied in post-discharge trauma patients.

Conclusions

The wide range of outcomes and outcome measures reported across different types of injuries and settings. This variability can be a barrier when comparing across different types of injuries and settings. Post-discharge trauma studies should move towards building evidence based on standardized measurement of outcomes.

Impacts of injury severity on long-term outcomes following motor vehicle crashes

Background

There is growing evidence that a range of pre-injury, injury related and post-injury factors influence social and health outcomes across the injury severity spectrum. This paper documents health related outcomes for people with mild, moderate and severe injury after motor vehicle crash (MVC) injuries in New South Wales, Australia.

Methods

This inception cohort study followed 2019 people injured in MVCs, for 6 and 12 months post-injury. We categorised moderate injury as hospital length-of-stay (LOS) of 2–6 days and Injury Severity Score (ISS) of 4–11, while severe injury as LOS ≥7 days or ISS ≥ 12. We examined differences in paid work status, 12-Item Short Form Survey (SF12), EQ-5D and World Health Organisation Disability Assessment Schedule II (WHODAS) outcomes longitudinally from baseline to 12 months between levels of injury severity using linear mixed models for repeated measures. We first considered minimally sufficient adjustment factors (age, sex, crash role, perceived danger in crash, pre-injury health, pre-injury EQ-5D, recruitment source), and then more extensive adjustments including post-injury factors. The presence of mediating pathways for SF-12 Physical Component Summary (PCS) and Mental Component Summary (MCS) via post-injury factors was evaluated.

Results

Based on hospital length of stay (LOS), 25 and 10% of participants sustained moderate and severe injuries, respectively, while 43 and 4% had these injuries based on ISS. Twelve months post-injury LOS ≥7 days versus ≤1 day was associated with an estimated 9 units lower mean SF12 PCS using a minimally sufficient adjustment model, and LOS ≥ 7 days was associated with a 3 units lower mean SF12 MCS score. Mediation analyses (LOS ≥ 7 days vs ≤1 day) found for SF12 MCS outcomes, effects of injury severity were small and mostly indirect (direct effect − 0.03, indirect effect − 0.22). Whereas for SF12 PCS outcomes the effect of having a more severe injury rather than mild were both direct and indirect (direct effect − 0.50, indirect effect − 0.38).

Conclusions

Individuals with severe injuries (those with LOS ≥ 7 days and ISS 12+) had poorer recovery 12 months after the injury. In addition, post-injury mediators have an important role in influencing long-term health outcomes.

Expert consensus and perspectives on recovery following road traffic crashes: a Delphi study

PURPOSE

To reach expert consensus on a definition for recovery following minor and moderate road traffic crash-related injuries and key factors that influence recovery, and to explore expert perspectives on risk identification methods.

MATERIALS AND METHODS

A three-round Delphi study was conducted in which 47 experts (insurance representatives, health care professionals and researchers) were consulted.

RESULTS

Strong expert agreement (86%) was reached for the definition: "Recovery is multifaceted and includes return to activities of daily living (ADLs), work and social/leisure activities at pre-injury level or at a level deemed acceptable by the individual, with minimal ongoing pain and symptoms, considering physical and mental health and wellbeing". Agreed key factors that influenced recovery included: resilience; coping skills; recovery expectations; pre-existing physical and mental health; workplace support; and, collaboration between the injured individual, treating providers and claim handlers. Expert perspectives on risk identification methods were mixed.

CONCLUSIONS

An accepted definition for recovery following minor and moderate road traffic crash-related injury was established, which could facilitate communication and engagement between different rehabilitation stakeholders. Strong consensus was achieved on nine key factors that influenced recovery. Further research is needed to evaluate whether injured persons agree with this definition and on the utility of risk identification methods.Implications for rehabilitationExpert consensus was established for a definition of recovery following minor and moderate road traffic crash-related injuries and nine key influencing factors.An established definition could facilitate communication and engagement between all rehabilitation stakeholders, which could improve the recovery process of the injured person.Rehabilitation professionals need to be familiar with the role of psychosocial factors, such as recovery expectations, resilience and coping skills, in the recovery process.The use of physical and psychological outcome measures at regular intervals could help to identify risk of poor recovery following minor and moderate road traffic crash-related injuries.

Health status and quality of life among road users with permanent medical impairment several years after the crash

OBJECTIVE

Improvements in road infrastructure and vehicle safety have been achieved in many countries during the last decades. As the number of fatalities have dropped, the consequences of non-fatal injuries have been brought into focus. Therefore, the objective was to investigate self-reported health status and health-related quality of life several years after the crash for road-users that sustained injuries resulting in permanent medical impairment (PMI).

METHODS

A self-administered questionnaire using instruments to measure if health, health-related quality of life and physical activity had been affected by the crash, were used. The injured road-users were identified from insurance policy holders of the Folksam Insurance Group. The response rate was 29%, a total of 2078 responses were received from the 7174 road-users with PMI that received the questionnaire.

RESULTS

In total 85% were still suffering from the injuries several years after the crash (8-18 year after the crash). Furthermore, road-users with injuries to the spine were having highest pain intensity. Older road-users had poorer self-reported health status than younger road-users. Although, younger road-users had the greatest change in physical activity when comparing before and after the crash. Before the crash in total 63% were physically active while only 34% after the crash. The higher the PMI the higher it affected health several years after the crash.

CONCLUSIONS

The Swedish definition of serious injury, an injury leading to PMI, was found to correlate with self-reported health loss; 85% of the injured road-users reported that they still had remaining symptoms several years after the accident. The injured body region leading to PMI after an accident can vary from the body regions reported to cause long-term health loss. It was found that the higher the degree of PMI the higher the health loss. Sustaining a PMI regardless severity and injured body region has the same effects on general health for men and women. Sustaining a PMI will both lower the health-related quality of life and physical activity after the crash compared to before.

Fifty Years of Accident Analysis & Prevention: A Bibliometric and Scientometric Overview

Accident Analysis & Prevention (AA&P) is a leading academic journal established in 1969 that serves as an important scientific communication platform for road safety studies. To celebrate its 50^th anniversary of publishing outstanding and insightful studies, a multi-dimensional statistical and visualized analysis of the AA&P publications between 1969 and 2018 was performed using the Web of Science (WoS) Core Collection database, bibliometrics and mapping-knowledge-domain (MKD) analytical methods, and scientometric tools. It was shown that the annual number of AA&P's publications has grown exponentially and that over the course of its development, AA&P has been a leader in the field of road safety, both in terms of innovation and dissemination. By determining its key source countries and organizations, core authors, highly co-cited published documents, and high burst-strength publications, we showed that AA&P's areas of focus include the "effects of hazard and risk perception on driving behavior", "crash frequency modeling analysis", "intentional driving violations and aberrant driving behavior", "epidemiology, assessment and prevention of road traffic injuries", and "crash-injury severity modeling analysis". Furthermore, the key burst papers that have played an important role in advancing research and guiding AA&P in new directions - particularly those in the fields of crash frequency and crash-injury severity modeling analyses were identified. Finally, a modified Haddon matrix in the era of intelligent, connected and autonomous transportation systems is proposed to provide new insights into the emerging generation of road safety studies.

Road traffic accidents of the elderly in Chile between the years 2008-2017: A register-based descriptive study

Objective

To determine whether Chilean elderly persons have higher rates of traffic incidents, resulting in death or injury, compared to non-older adults between 2008 and 2017.

Method

The databases of the National Traffic Safety Commission of the last ten years and the data of inhabitants according to the projections made by the National Statistics Institute were used. Effect measures and 95% confidence intervals were calculated.

Results

Older adults in Chile had 0.5 times the rate of suffering a traffic accident, 0.6 times the rate of injury, and 1.3 times the rate of dying in a traffic accident when compared against non-elderly adults. Antofagasta and Arica were the regions with the lowest and highest occurrence of death for the elderly, respectively. The leading causes of traffic accidents were the imprudence of the driver and pedestrian, which presented 1.6 and 2.6 times the death rate when compared against non-elderly adults. Of the main types of traffic accidents, only when the pedestrian was hit by a vehicle, the elderly had a higher occurrence of death (rate ratio: 2.4).

Conclusions

The elderly presented greater vulnerability to die in a traffic accident. Substantial differences are seen across different regions. Future research should address the characteristics of the users, the strategies that could help them to have better interaction, and promote health with a focus on road safety in the elderly.

Health-Related Quality of Life in Motorcycle Crash Victims One Year After Injury: A Longitudinal Study in Ho Chi Minh City, Vietnam

Despite the burden of injury associated with motorcycle crashes and injuries in Vietnam, there are no studies investigating health-related quality of life (HRQoL) following a nonfatal motorcycle crash in this country. Therefore, this study aimed to evaluate the change of HRQoL preinjury, and at 6 and 12 months postinjury motorcycle crash in Ho Chi Minh City, Vietnam. Outcome measures were Physical Component Scores (PCS) and Mental Component Scores (MCS) of the Short Form 12 Health Survey (SF-12) version 2 and the EQ-5D. Multilevel mixed models were undertaken. A total of 352 hospitalized motorcyclists were followed-up. Compared with preinjury, the SF-12 PCS reduced by 6.61 points (95% confidence interval [CI] = -8.21 to -5.03) and 5.12 points (95% CI = -6.74 to -3.51) at 12 months postinjury. MCS also reduced by 4.23 points (95% CI = -5.99 to -2.47) at 6 months but increased by 1.29 points (95% CI = -0.49 to 3.08) at 12 months postinjury. The EQ-5D Visual Analogue Scale score decreased by 10.41 points (95% CI = -11.49 to -9.33) at 6 months and 6.48 points (95% CI = -7.58 to -5.38) at 12 months postinjury. The HRQoL among injured motorcycle riders improved between 6 and 12 months after injury but had not returned to the levels before injury.

Quality of life following road traffic injury: the impact of age and gender

Purpose

The impact of road traffic crashes on health is well developed, in terms of deaths and direct consequences, but it is less so in terms of long-term life consequences. Few studies have compared the general impact on Health Related Quality of Life (HRQoL) following road traffic injury (RTI) by using a variety of different injured body parts and severity levels of the injury and compared them with a sample of non-injured referent individuals. Consequently, the aim of the current study is to assess how injury severity is associated with HRQoL, and if it differs between men, women, over age and injured body parts.

Methods

This cross-sectional study identified people with a RTI in the Swedish Traffic Accident Data Acquisition System (STRADA). A frequency matched reference group was also included. Data include both register data and self-reported HRQoL data.

Results

A total of 1788 out of 4761 persons with an RTI (37.6%) and 2186 out of 4761 reference persons (45.9%) returned the questionnaire, giving a total response rate of 41.9% (n = 3974). The findings show different patterns of HRQoL loss, depending on sex, age, injured body part, and levels of injury severity.

Conclusion

The results show that even relatively minor road traffic injuries can lead to a significantly lower of HRQoL, especially for women, compared to the non-injured reference group. Moreover, when the inherent reduction of HRQoL over age was considered, the results indicated that younger individuals have a larger difference from the reference group in HRQoL, independent of the injury severity, compared to the older individuals; hence, an improved understanding of age and gender differences in HRQoL following an RTI is needed to better understand the long-term consequences of injuries from a public health perspective.

Road Safety in Low-Income Countries: State of Knowledge and Future Directions

Road safety in low-income countries (LICs) remains a major concern. Given the expected increase in traffic exposure due to the relatively rapid motorisation of transport in LICs, it is imperative to better understand the underlying mechanisms of road safety. This in turn will allow for planning cost-effective road safety improvement programs in a timely manner. With the general aim of improving road safety in LICs, this paper discusses the state of knowledge and proposes a number of future research directions developed from literature reviews and expert elicitation. Our study takes a holistic approach based on the Safe Systems framework and the framework for the UN Decade of Action for Road Safety. We focused mostly on examining the problem from traffic engineering and safety policy standpoints, but also touched upon other sectors, including public health and social sciences. We identified ten focus areas relating to (i) under-reporting; (ii) global best practices; (iii) vulnerable groups; (iv) disabilities; (v) road crash costing; (vi) vehicle safety; (vii) proactive approaches; (viii) data challenges; (ix) social/behavioural aspects; and (x) capacity building. Based on our findings, future research ought to focus on improvement of data systems, understanding the impact of and addressing non-fatal injuries, improving estimates on the economic burden, implementation research to scale up programs and transfer learnings, as well as capacity development. Our recommendations, which relate to both empirical and methodological frontiers, would lead to noteworthy improvements in the way road safety data collection and research is conducted in the context of LICs.

Identifying risk of poor physical and mental health recovery following a road traffic crash: An industry-specific screening tool

This study aimed to develop an industry-specific tool to identify risk of poor physical and mental recovery following minor to moderate injuries sustained in a road traffic crash (RTC). Existing tools are often designed for implementation by health professionals rather than insurer case managers who may not have a background in health. This study is a secondary analysis of a longitudinal cohort study using data collected at 2-6 months and 24 months post-RTC. Participants were claimants (n = 254; Mean age = 50 years; 65% female) with mild-moderate injuries recruited through the common-law 'fault-based' compulsory third party scheme in Queensland, Australia. Sociodemographic, functional and psychological health factors were collected at baseline (2-6 months post RTC) and used as potential predictors for physical and mental health-related quality of life (Short Form 36 v2) at the 2-year follow-up. The LASSO (Least Absolute Shrinkage and Selection Operator) analysis identified six disability items (from the World Health Organization Disability Assessment Schedule 2) to predict poor physical and one item to predict poor mental health-related quality of life. Logistic regressions of these items in addition to age and gender were used to develop a screening tool. Using the tool, 90% of those at risk of poor physical and 80% of those at risk of poor mental health-related quality of life were identified correctly. To conclude, this study presents an 8-item, context-specific tool to help injury managers identify individuals at risk of poor physical and mental health recovery following mild-moderate RTC-related injuries. The tool requires validation in a new cohort and confirmation of acceptability by end-users.

Burden of musculoskeletal-related disorders resulting from non-fatal road traffic collisions in Africa: a protocol of a systematic review

INTRODUCTION

In addition to their high mortality rates, road traffic collisions (RTC) are considered a burden within those who do survive. In Africa, injuries related to RTC have been identified as the 10th most common cause of disability-adjusted life years lost for all ages and categories. Moreover, non-fatal RTC are the biggest cause associated with the burden of musculoskeletal disorders (MSD) in Africa. Despite this, the epidemiology of MSD related to non-fatal RTC within this region is still unknown.The objective of this review is to identify and summarise available data regarding the prevalence, incidence and patterns of MSD resulting from non-fatal RTC in Africa.

METHODS AND ANALYSIS

A systematic review of observational epidemiological studies will be conducted. On October 2019, MEDLINE, Embase, CINAHL Plus, PsycINFO, Web of Science, Global Health and African Journals OnLine will be searched for literature that is in English and published between 1990 and 2018. Two reviewers (MY ad TG) will independently screen results and extract the data, with a third reviewer (FF) resolving any discrepancies through discussion. Additionally, two reviewers (MY and TG) will independently assess the quality of the eligible studies using the US National Institutes of Health National Heart, Lung, and Blood Institute Quality Assessment Tool.Within the eligible studies, data on citation, methods and results will be extracted. Extracted data will be analysed using a narrative synthesis. Findings will be presented in tables, with the main outcomes being prevalence, incidence and disease pattern of MSD and determinants of non-fatal RTC. The final systematic review will be conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline.

ETHICS AND DISSEMINATION

As individual patients will not be involved in this study, no ethical approval will be sought. Findings from this review will be disseminated through peer-reviewed journals and relevant conferences.

Change in sense of coherence and health-related quality of life after injury - a prospective cohort study

PURPOSE

To investigate how accidents leading to fracture affect sense of coherence and health-related quality of life 6 months later and the association between the two phenomena.

MATERIALS AND METHODS

A cohort study including 201 patients admitted to hospital with fractures was conducted. Data were based on structured interviewing a few days after admission and 6 months later. Sense of coherence was evaluated with a nine-item scale and health-related quality of life was examined with the subscales of Short Form-36 (SF-36).

RESULTS

Follow-up comprised 164 patients (81.6%), mean age 47 years. Sense of coherence changed to be either stronger (43%) or weaker (41%) and was stable for 15.9% of the participants. Health-related quality of life changed positively after 6 months but did not reach normative values. Strong sense of coherence was significantly associated with the SF-36 subscales emotional role functioning, social functioning, vitality, and mental health.

CONCLUSIONS

Accidents leading to fracture can be stressful life events that could influence an individual's sense of coherence to be stronger or weaker. The association between sense of coherence and health-related quality of life emphasises the importance of therapists supporting the patients' personal resources and promote a salutogenic focus.IMPLICATIONS FOR REHABILITATIONAn injury may change an individual's sense of coherence to be stronger or weaker.For patients who sustain fracture, sense of coherence should be included in therapists' analysis of personal resources and support a salutogenic perspective.Health-related quality of life is especially for younger individuals affected by an accident and its consequences and need a guided and meticulous rehabilitation course.

Quality of life in the limelight: a study protocol of a Swedish register-based cohort study on quality of life after an injury

INTRODUCTION

Currently, there are very few published studies on preinjury and postinjury assessments of quality of life (QoL) based on a prospective appraisal; specifically, knowledge of those who do not seek medical care following injury is lacking. To close these knowledge gaps, this study aims to identify the psychosocial consequences in terms of loss of QoL following injury in a Swedish population and to investigate the response shift in retrospective measures of self-reported QoL.

METHODS AND ANALYSIS

We will analyse preinjury and postinjury (including both minor and severe unintentional injuries as well as different injury mechanisms) assessments of QoL, including the phenomenon of response shift, using register-based data from the nationwide collaboration project LifeGene, which includes over 52 000 individuals living in Sweden. In addition to LifeGene data, a short online survey including a 'ThenTest' questionnaire, that is, comparison of previous QoL to current using EuroQoL five-dimensional questionnaire, was sent out to the participants of LifeGene. This study will provide a unique opportunity to study the changes in QoL by comparing preinjury and postinjury assessments using a prospective appraisal, both for populations who have sought medical care as well as those who have not due to their injury. Similarly, the study will also assess the response shift in retrospective measures of QoL. This information can guide the next generation of QoL measures and interventions for those suffering injuries and have an impact on how to interpret evaluations of interventions.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the Regional Ethical Review Board in Stockholm, Sweden (case number 2018/352-31). The results will be disseminated through peer-reviewed journals, conference presentations, print media and internet and via a report for the funding agency.

Psychosocial and quality of life impact of scars in the surgical, traumatic and burn populations: a scoping review protocol

INTRODUCTION

Despite the fact that millions of scars affect individuals annually, little is known about their psychosocial impact and overall quality of life (QOL) on individuals. Scars from multiple aetiologies may cause psychiatric and emotional disturbances, can limit physical functioning and increase costs to the healthcare system. The purpose of this protocol is to describe the methodological considerations that will guide the completion of a scoping review that will summarise the extent, range and nature of psychosocial health outcomes and QOL of scars of all aetiologies.

METHODS AND ANALYSIS

A modified Arksey and O'Malley (2005) framework will be completed, namely having ongoing consultation between experts from the beginning of the process, then (1) identifying the research question/s, (2) identifying the relevant studies from electronic databases and grey literature, with (3) study selection and (4) charting of data by two independent coders, and (5) collating, summarising and reporting data. Experts will include a health information specialist (TAW), scar expert (JSF), scoping review consultant (SCK), as well as at least two independent coders (NZ, AM).

ETHICS AND DISSEMINATION

Ethics approval will not be sought for this scoping review. We plan to disseminate this research through publications, presentations and meetings with relevant stakeholders.

Trajectory of functional outcome and health status after moderate-to-major trauma in Hong Kong: A prospective 5 year cohort study

BACKGROUND

Trauma care systems in Asia have been developing in recent years, but there has been little long-term outcome data from injured survivors. This study aims to evaluate the trajectory of functional outcome and health status up to five years after moderate to major trauma in Hong Kong.

METHODS

We report the five year follow up results of a multicentre, prospective cohort from the trauma registries of three regional trauma centres in Hong Kong. The original cohort recruited 400 adult trauma patients with ISS ≥ 9. Telephone follow up was conducted longitudinally at seven time points, and the extended Glasgow Outcome Scale (GOSE) and Short-Form 36 (SF36) were tracked.

RESULTS

119 out of 309 surviving patients (39%) completed follow up after 5 years. The trajectory of GOSE, PCS and MCS showed gradual improvements over the seven time points. 56/119 (47.1%) patients reported a GOSE = 8 (upper good recovery), and the mean PCS and MCS was 47.8 (95% CI 45.8, 49.9) and 55.8 (95% CI 54.1, 57.5) respectively at five years. Univariate logistic regression showed change in PCS - baseline to 1 year and 1 year to 2 years, and change in MCS - baseline to 1 year were associated with GOSE = 8 at 5 years. Linear mixed effects model showed differences in PCS and MCS were greatest between 1-month and 6-month follow up.

CONCLUSIONS

After injury, the most rapid improvement in PCS and MCS occurred in the first six to 12 months, but further recovery was still evident for MCS in patients aged under 65 years for up to five years.

Health-Related Quality of Life Profiles among Patients with Different Road Traffic Injuries in an Urban Setting of Vietnam

Road traffic injuries (RTIs) cause a substantial disease burden in Vietnam. Evaluating health-related quality of life (HRQOL) among patients having a diversity of RTIs informs an integral part of treatment effectiveness. This study aims to examine HRQOL of patients suffering different RTIs in Vietnam’s urban areas. A cross-sectional study was conducted on 408 patients from October to December 2018 in six hospitals in Thai Binh. The EuroQol-5 dimensions-5 levels (EQ-5D-5L) and visual analog scale (VAS) were used to assess the HRQOL of patients. Multivariable Tobit regression was applied to measure the difference of HRQOL among different kinds of injuries. The mean EQ-5D-5L and VAS score was 0.40–0.66, respectively. Mean EQ-5D-5L index was lowest in patients with oral and facial injuries (0.22) and fracture injuries (0.23), while patients having hand injuries had the highest EQ-5D-5L index (0.54). EQ-5D-5L index had a negative association with oral, facial, and fracture injuries. Meanwhile, patients with brain, fracture, and multiple injuries tended to have lower VAS score. Poor HRQOL among patients injured in road traffic were observed. Pain management, early rehabilitation, and mental health counseling services should be considered during treatment time, especially among those having the brain, oral and facial trauma, fracture, and multiple injuries.

Effect of white-coat hypertension on arterial stiffness: A meta-analysis

BACKGROUND

White-coat hypertension (WCH) is a debatable risk factor of cardio-cerebrovascular diseases and the current study results on the association between WCH and arterial stiffness are inconsistent. The aim was to investigate the effect of WCH on arterial stiffness using meta-analysis.

METHODS

Based on prespecified search strategies and inclusion criteria, Medline, Embase, Web Of Science, Cochrane Library, and BioSciences Information Service Preview databases were reviewed. A total of 20 studies involving 1538 WCH patients and 3582 normotensives (NT) were included. Literatures were screened for data extraction and quality assessment. Overall analysis and subgroup analysis were conducted in RevMan version 5.3 and Stata version 14.0 software.

RESULTS

Overall analysis showed that carotid-femoral pulse wave velocity (cf-PWV) was significantly higher in WCH group than in the NT group (P < .00001, 95% CI: 0.79-3.26). Subgroup analysis showed that in adults, cf-PWV was significantly higher in the WCH patients than in the NT subjects (P<.001, 95% CI: 0.46-0.87), while in juveniles, cf-PWV was comparable between the WCH group and the NT group (P = .25, 95% CI: -0.39 to 0.61).

CONCLUSION

This meta-analysis showed that WCH may increase arterial stiffness in adult population.
