Rural and urban patterns of severe injuries and hospital mortality in Australia: An analysis of the Australia New Zealand Trauma Registry: 2015-2019.

INTRODUCTION: In Australia, people living in rural areas, compared to major cities are at greater risk of poor health. There is much evidence of preventable disparities in trauma outcomes, however research quantifying geographic variations in injuries, pathways to specialised care and patient outcomes is scarce. AIMS: (i) To analyse the Australia New Zealand Trauma Registry (ATR) data and report patterns of serious injuries according to rurality of the injury location ii) to examine the relationship between rurality and hospital mortality and iii) to compare ATR death rates with all deaths from similar causes, Australia-wide. METHOD: A retrospective cohort study of patients in the ATR from 1st July 2015 to 30th June 2019 was conducted. Descriptive analyses of trauma variables according to rurality was performed. Logistic regression quantified the moderating effect of rurality on trauma variables and hospital mortality. Australian death data on similar injuries were sourced to quantify the additional mortality attributable to severe injury occurring outside Major Trauma Centres (MTCs). RESULTS: Compared to major cities, rural patients were younger, more likely to have spinal cord injuries, and sustain traffic-related injuries that are 'off road'. Injuries occurring outside people's homes are more likely. Mortality risk was greater for patients sustaining severe traumatic brain injury (TBI) spinal cord injury (SCI) and head trauma in addition to intentional injuries. Compared to the ATR data, Australian population-wide trauma mortality rates showed diverging trends according to rurality. The ATR only captures 14.1% of all injury deaths occurring in major cities and, respectively, 6.3% and 3.2% of deaths in regional and remote areas. CONCLUSION: Compared to major cities, injuries occurring in rural areas of Australia often involve different mechanisms and result in different types of severe injuries. Patients with neurotrauma and intentional injuries who survived to receive definitive care at a MTC were at higher risk of hospital death. To inform prevention strategies and reduce morbidity and mortality associated with rural trauma, improvements to data systems are required that involve data linkage and include information about patient care from pre-hospital providers, regional hospitals and major trauma centres.

Caregiver resilience and patients with severe musculoskeletal traumatic injuries.

AIMS: This study investigated the association of resilience on caregiver burden and quality of life in informal caregivers of patients with severe traumatic musculoskeletal injuries. METHODS: A prospective cohort study of eligible caregivers and acutely injured trauma patients was conducted during 2018 in South East Queensland, with follow-up 3 months after patient discharge. Resilience was examined using the 10-item Connor Davidson Resilience Scale. The primary outcomes, caregiver burden and quality of life were measured respectively, using the Caregiver Strain Index and the Short Form Version 12 Health Survey. RESULTS: Baseline measures were completed with fifty-three (77%) patient/carer dyads. Thirty-eight (28%) were available for follow up at 3 months. Significant reductions from baseline were found at follow up, for levels of resilience, mental health, physical exercise and community support. In multiple regression models, caregiver resilience at follow-up independently predicted lower caregiver burden (ß = -0.74, p = 0.008) and higher levels of patient physical health and function (ß = -0.69, p = 0.003). CONCLUSIONS: Upon commencing informal care, caregivers' resilience, mental health and support systems are adversely affected. Higher levels of caregiver resilience appear to be protective against caregiver burden and declines in patient physical function. Early evaluation of caregivers' resilience, their physical and mental health and socio-ecological networks could improve carer and patient health outcomes.Implications for rehabilitationAfter 3 months of providing informal care to severely injured musculoskeletal trauma patients, there are apparent declines in their mental health, resilience, community support and physical activity levels. However, those with higher levels of resilience compared to lower levels could be protected against caregiver burden. Higher caregiver resilience could also prevent declines in patients' physical function.The rehabilitation of severe trauma patients should additionally include routine assessment and management of informal caregivers with the aim to prevent caregiver burden.Early clinical assessment of caregiver resilience using a valid resilience measurement tool could identify caregivers at risk of caregiver burden and flag vulnerable caregivers for ongoing support in the community.Early assessment of caregivers' physical and mental health and health related behaviours could flag the need for health promotion interventions aimed at supporting caregivers' physical and mental health.

Avoidable Mortality Attributable to Anthropogenic Fine Particulate Matter (PM2.5) in Australia.

Ambient fine particulate matter <2.5 µm (PM2.5) air pollution increases premature mortality globally. Some PM2.5 is natural, but anthropogenic PM2.5 is comparatively avoidable. We determined the impact of long-term exposures to the anthropogenic PM component on mortality in Australia. PM2.5-attributable deaths were calculated for all Australian Statistical Area 2 (SA2; n = 2310) regions. All-cause death rates from Australian mortality and population databases were combined with annual anthropogenic PM2.5 exposures for the years 2006-2016. Relative risk estimates were derived from the literature. Population-weighted average PM2.5 concentrations were estimated in each SA2 using a satellite and land use regression model for Australia. PM2.5-attributable mortality was calculated using a health-impact assessment methodology with life tables and all-cause death rates. The changes in life expectancy (LE) from birth, years of life lost (YLL), and economic cost of lost life years were calculated using the 2019 value of a statistical life. Nationally, long-term population-weighted average total and anthropogenic PM2.5 concentrations were 6.5 µg/m3 (min 1.2-max 14.2) and 3.2 µg/m3 (min 0-max 9.5), respectively. Annually, anthropogenic PM2.5-pollution is associated with 2616 (95% confidence intervals 1712, 3455) deaths, corresponding to a 0.2-year (95% CI 0.14, 0.28) reduction in LE for children aged 0-4 years, 38,962 (95%CI 25,391, 51,669) YLL and an average annual economic burden of $6.2 billion (95%CI $4.0 billion, $8.1 billion). We conclude that the anthropogenic PM2.5-related costs of mortality in Australia are higher than community standards should allow, and reductions in emissions are recommended to achieve avoidable mortality.

The Importance of Place of Residence on Hospitalized Outcomes for Severely Injured Trauma Patients: A Trauma Registry Analysis.

PURPOSE: Socioecological factors are understudied in relation to trauma patients' outcomes. This study investigated the association of neighborhood socioeconomic disadvantage (SED) and remoteness of residence on acute length of hospital stay days (ALSD) and inpatient mortality. METHODS: A retrospective cohort study was conducted on adults hospitalized for major trauma in a Level 1 trauma center in southeast Queensland from 2014 to 2017. Neighborhood SED and remoteness indices were linked to individual patient variables. Step-wise multivariable negative binomial regression and proportional hazards regression analyses were undertaken, adjusting for injury and patient factors. Outcomes were ALSD and inpatient mortality. FINDINGS: We analyzed 1,025 patients. Statistically significant increased hazard of inpatient mortality was found for older age (HR 3.53, 95% CI: 1.77-7.11), injury severity (HR 5.27, 95% CI: 2.78-10.02), remoteness of injury location (HR 1.75, 95% CI: 1.06-2.09), and mechanisms related to intentional self-harm or assault (HR 2.72, 95% CI: 1.48-5.03,). Excess mortality risk was apparent for rural patients sustaining less severe injuries (HR 4.20, 95% CI: 1.35-13.10). Increased risk for longer ALSD was evident for older age (RR 1.35, 95% CI: 1.07-1.71), head injury (RR 1.39, 95% CI: 1.19-1.62), extremity injuries (RR 1.82, 95% CI: 1.55-2.14), and higher injury severity scores (ISS) (RR 1.51, 95%: CI: 1.29-1.76). CONCLUSIONS: Severely injured rural trauma patients are more likely to be socioeconomically disadvantaged and sustain injuries predisposing them to worse hospital outcomes. Further research is needed to understand more about care pathways and factors influencing the severity, mechanism and clinical consequences of rural-based traumatic injuries.

The effectiveness of multi-dimensional resilience rehabilitation programs after traumatic physical injuries: a systematic review and meta-analysis.

Objective: To synthesize evidence of the effectiveness of socio-ecological resilience rehabilitation programs on returning to work (RTW), self-efficacy, and stress mitigation following traumatic physical injuries.Methods: PubMed, Scopus, Proquest, Cinahl, Web of Science, Clinical Trials Database, and the Cochrane Central Register of Controlled Trials databases were searched. Methodological quality was assessed using the PEDro tool.Study selection: Randomized interventions aimed at promoting resilience.Data extraction: Twenty one studies were reviewed (11,904 participants). Data from 19 studies of high methodological quality were pooled using a random-effects meta-analysis. Mean differences for continuous outcomes and risk ratios for binary outcomes were calculated.Data synthesis: Resilience rehabilitation programs significantly increased the likelihood of ever RTW (OR 2.09, 95% CI 0.99-4.44, p = 0.05), decreased the number of days taken to return to work (mean difference -7.80, 95% CI -13.16 to -2.45, p ≤ 0.001), and increased total self-efficacy scores (mean difference 5.19, 95% CI 3.12-7.26, p < 0.001). Subgroup analyses found that favorable return to work outcomes resulted from programs involving workplace support (p < 0.001) and for people with musculoskeletal or orthopedic injuries (p = 0.02).Conclusions: Compared to rehabilitation programs providing standard care following injuries, programs aimed at developing resilience could improve reemployment outcomes and self-efficacy.Implications for rehabilitationIndividual resilience may be an important factor promoting functional recovery after traumatic injury.Resilience rehabilitation programs are effective in enabling patients' return to work and increasing their self efficacy. In particular, programs involving the workplace are important components for enabling optimal work participation outcomes.

A randomized controlled trial of an enhanced interdisciplinary community based group program for people with Parkinson's disease: study rationale and protocol.

Parkinson's disease (PD) is a progressive, chronic neurodegenerative disorder for which there is no known cure. Physical exercise programs may be used to assist with the physical management of PD. Several studies have demonstrated that community based physical therapy programs are effective in reducing physical aspects of disability among people with PD. While multidisciplinary therapy interventions may have the potential to reduce disability and improve the quality of life of people with PD, there is very limited clinical trial evidence to support or refute the use of a community based multidisciplinary or interdisciplinary programs for people with PD. A two group randomized trial is being undertaken within a community rehabilitation service in Brisbane, Australia. Community dwelling adults with a diagnosis of Idiopathic Parkinson's disease are being recruited. Eligible participants are randomly allocated to a standard exercise rehabilitation group program or an intervention group which incorporates physical, cognitive and speech activities in a multi-tasking framework. Outcomes will be measured at 6-week intervals for a period of six months. Primary outcome measures are the Montreal Cognitive Assessment (MoCA) and the Timed Up and Go (TUG) cognitive test. Secondary outcomes include changes in health related quality of life, communication, social participation, mobility, strength and balance, and carer burden measures. This study will determine the immediate and long-term effectiveness of a unique multifocal, interdisciplinary, dual-tasking approach to the management of PD as compared to an exercise only program. We anticipate that the results of this study will have implications for the development of cost effective evidence based best practice for the treatment of people with PD living in the community.

Correlates of comorbid mental disorders in a regional community-based sample.

OBJECTIVE: The common coexistence of psychiatric disorders has been identified as a significant factor contributing to the disability associated with mental illness. Identifying indicators to the development of coexisting disorders has potential clinical implications. This study aimed to investigate the correlates and impact of coexisting disorders in a rural setting. DESIGN: Cross-sectional analyses of data from a cohort interviewed in two phases. SETTING: A regional community sample in Northern New South Wales, Australia. PARTICIPANTS: A total of 1407 participants were interviewed and 968 were re-interviewed at follow up. MAIN OUTCOME MEASURES: Multinomial logistic regression modelling compared subjects with multiple psychiatric disorders with those with a single disorder for sociodemographic characteristics, measures of personal and social vulnerability, psychological distress, functional disabilities and help-seeking behaviours. RESULTS: Participants with coexisting disorders were more likely to be male, report a history of severe childhood assault and had higher levels of neuroticism, psychological distress and help-seeking behaviour. CONCLUSIONS: The findings suggest the role of early developmental factors on the complexity and severity of adult mental illness in a rural setting and the significant clinical consequences of comorbidity.
