The prevalence of helmet use in motorcyclists around the world: a systematic review and meta-analysis of 5,006,476 participants.

Road traffic injuries present a significant public health burden, especially in developing countries. This systematic review and meta-analysis synthesized global evidence on motorcycle helmet use prevalence by including 299 records across 249 articles involving 5,006,476 participants from 1982 to 2022. The findings revealed a declining trend in helmet use prevalence over the past four decades, with an overall prevalence of 48.71%. The meta-regression analysis did not find any statistically significant change in the overall prevalence. Subgroup analysis showed higher helmet use prevalence in observation/survey records (54.29%) compared to crashed patient records (44.84%). Riders/Motorcyclists demonstrated a higher likelihood of wearing helmets than passengers in both observation/survey records (62.61 vs. 28.23%) and crashed patient records (47.76 vs. 26.61%). Countries with mandatory helmet use laws had higher helmet usage prevalence compared to those without (52.26 vs. 37.21%). The African continent had the lowest helmet use rates, while Latin America and the Caribbean regions had higher rates. This study provides a comprehensive overview of global helmet use prevalence, emphasizing disparities between high and low-income countries, variations in law enforcement, and trends over four decades. Targeted interventions are necessary to improve helmet-wearing habits, especially among passengers and regions with low usage rates. Effective legislation and awareness campaigns are crucial for promoting helmet use and reducing road traffic injuries burden.

Modelled economic evaluation of a virtual emergency department in Victoria.

OBJECTIVE: Virtual ED (VED) can potentially alleviate ED overcrowding which has been a public health challenge. The aim of the present study was to conduct a return-on-investment analysis of a VED programme developed in response to changing healthcare needs in Australia. METHODS: An economic model was developed based on initial patient outcome data to assess the healthcare costs, potential costs saved and return on investment (ROI) from the VED. The VED programme operating as part of Alfred Health Emergency Services. The participants were the first 188 patients accessing the Alfred Health VED. VED is the delivery of emergency assessment and management of specific patients virtually via audio-visual teleconferencing. ROI ratios that compare cost savings with intervention costs. RESULTS: The mean total operational cost of VED for 79 days for 188 patients was A$344 117 (95% uncertainty interval [UI] $296 800-$392 088). The VED led to a potential A$286 779 (95% UI $241 688-$330 568) healthcare cost saving from reductions in emergency visits and A$97 569 (95% UI $74 233-$123 117) cost saving in ambulance services. The ROI ratio was estimated at 1.12 (95% UI 0.96-1.32). CONCLUSIONS: The VED was cost neutral in a conservatively modelled scenario but promising if any hospital admission could be saved. Ongoing research examining a larger cohort with community follow up is required to confirm this promising result.

Development of a comprehensive assessment tool to measure the quality of care for individuals with traumatic spinal cord injuries.

OBJECTIVE: To develop a comprehensive assessment tool to evaluate the Quality of Care (QoC) in managing individuals with traumatic spinal cord injuries (TSCI). METHOD: At first, the concepts of QoC for TSCI were identified by conducting a qualitative interview along with re-evaluation of the results of a published scoping review (conceptualization). After operationalization of indicators, they were valued by using the expert panel method. Afterward, the content validity index (CVI) and content validity ratio (CVR) were calculated and served as cut-offs for indicator selection. Then specific questions were developed for each indicator and classified into three categories: pre-hospital, in-hospital, and post-hospital. Data availability of the National Spinal Cord Injury Registry of Iran (NSCIR-IR) was subsequently used to design questions that represent indicators in an assessment tool format. The comprehensiveness of the tool was evaluated using a 4-item Likert scale by the expert panel. RESULT: Twelve experts participated in conceptualization and 11 experts participated in operationalization phase. Overall, 94 concepts for QoC were identified from published scoping review (87 items) and qualitative interviews (7 items). The process of operationalization and indicator selection led to the development of 27 indicators with acceptable content validity. Finally, the assessment tool contained three pre-hospital, twelve in-hospital, nine post-hospital, and three mixed indicators. Ninety-one percent of experts evaluated the entire tool as comprehensive. CONCLUSION: Our study presents a health-related QoC tool that contains a comprehensive set of indicators to assess the QoC for individuals with TSCI. However, this tool should be used in various situations to establish construct validity further.

Epidemiology and clinical features of emergency department patients with suspected and confirmed COVID-19: A multisite report from the COVID-19 Emergency Department Quality Improvement Project for July 2020 (COVED-3).

OBJECTIVE: The aim of the present study was to describe the epidemiology and clinical features of patients presenting to the ED with suspected and confirmed COVID-19. METHODS: The COVID-19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from eight sites across Victoria and Tasmania for July 2020 (during Australia's 'second wave'). All adult patients who met criteria for 'suspected COVID-19' and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes included a positive SARS-CoV-2 test result and mechanical ventilation. RESULTS: In the period 1 July to 31 July 2020, there were 30 378 presentations to the participating EDs and 2917 (9.6%; 95% confidence interval 9.3-9.9) underwent testing for SARS-CoV-2. Of these, 50 (2%) patients returned a positive result. Among positive cases, two (4%) received mechanical ventilation during their hospital admission compared to 45 (2%) of the SARS-CoV-2 negative patients (odds ratio 1.7, 95% confidence interval 0.4-7.3; P = 0.47). Two (4%) SARS-CoV-2 positive patients died in hospital compared to 46 (2%) of the SARS-CoV-2 negative patients (odds ratio 1.7, 95% confidence interval 0.4-7.1; P = 0.49). Strong clinical predictors of a positive SARS-CoV-2 result included self-reported fever, non-smoking status, bilateral infiltrates on chest X-ray and absence of a leucocytosis on first ED blood tests (P < 0.05). CONCLUSION: In this prospective multi-site study from July 2020, a substantial proportion of ED patients required SARS-CoV-2 testing, isolation and enhanced infection prevention and control precautions. Presence of SARS-CoV-2 on nasopharyngeal swab was not associated with death or mechanical ventilation.

Demand for global health training and experiences among emergency medicine trainees in Australia and New Zealand.

OBJECTIVE: Demand for global health (GH) training and experiences among emergency medicine trainees is unknown. The primary objective of the Trainee Interest in Global Health Training (TIGHT) study was to quantify the number of trainees interested in completing a rotation in a resource-limited environment within a low- or middle-income country during their specialty training. METHODS: A cross-sectional study of trainees in seven specialty training programmes was conducted between August and October 2018. Data were collected using a voluntary, anonymous, self-reporting, web-based survey. This study describes the results of a planned sub-group analysis of ACEM trainees. RESULTS: There were 203 respondents among 2525 ACEM trainees. Although only a small number (36/198, 18.2%) had undertaken a GH experience as a specialty trainee, 85.6% (167/195) were keen to do so. The vast majority of respondents (179/194, 87.1%) were interested or very interested in having their GH experience accredited for training, but 68.9% (133/193) reported that accessing a suitable placement was a barrier. More than 79% (147/186) expressed interest in undertaking an integrated GH training or fellowship programme as an adjunct to specialty training. CONCLUSIONS: Notwithstanding the limitations of a self-reporting survey with a sub-optimal response rate, there is significant demand for GH training and experiences among ACEM trainees. These findings should inform the development of safe and effective global emergency care training pathways, underpinned by mutually beneficial, international partnerships with educational and development objectives.

Trends in the drowning mortality rate in Iran.

OBJECTIVE: The WHO estimates the global incidence of death by drowning to be about 300 000 cases per year. The objective of this study was to estimate the trend in mortality due to drowning in all provinces of Iran in all age groups and both genders from 1990 to 2015. STUDY DESIGN: The National and Subnational Burden of Diseases (NASBOD) project is a comprehensive project in Iran. It is based on the Global Burden of Disease study and includes novel methods to estimate the burden of diseases in Iran. METHODS: This study used the results of the mortality rate due to drowning as part of NASBOD and investigated the causes behind the mortality rates. The data set recorded mortality rates by 19 age groups and two genders with the corresponding subnational pattern during the time period from 1990 to 2015. RESULTS: The drowning mortality rate decreased in Iran from 1990 to 2015. From 1990 to 2015, the annual percentage change for males and females was -5.28% and -10.73%, respectively. There were 56 184 male and 21 589 female fatalities during the study period. The highest number of deaths was seen in 1993 with 4459, and the lowest number of fatalities was observed in 2015 with 903 deaths. CONCLUSION: Our data showed a decline in drowning mortality in Iran from 1990 to 2015, but the rates and declines varied by province. Our findings are of great importance to health officials and authorities in order to further reduce the burden of drowning.

Towards developing a consensus assessment framework for global emergency medicine fellowships.

BACKGROUND: The number of Global Emergency Medicine (GEM) Fellowship training programs are increasing worldwide. Despite the increasing number of GEM fellowships, there is not an agreed upon approach for assessment of GEM trainees. MAIN BODY: In order to study the lack of standardized assessment in GEM fellowship training, a working group was established between the International EM Fellowship Consortium (IEMFC) and the International Federation for Emergency Medicine (IFEM). A needs assessment survey of IEMFC members and a review were undertaken to identify assessment tools currently in use by GEM fellowship programs; what relevant frameworks exist; and common elements used by programs with a wide diversity of emphases. A consensus framework was developed through iterative working group discussions. Thirty-two of 40 GEM fellowships responded (80% response). There is variability in the use and format of formal assessment between programs. Thirty programs reported training GEM fellows in the last 3 years (94%). Eighteen (56%) reported only informal assessments of trainees. Twenty-seven (84%) reported regular meetings for assessment of trainees. Eleven (34%) reported use of a structured assessment of any sort for GEM fellows and, of these, only 2 (18%) used validated instruments modified from general EM residency assessment tools. Only 3 (27%) programs reported incorporation of formal written feedback from partners in other countries. Using these results along with a review of the available assessment tools in GEM the working group developed a set of principles to guide GEM fellowship assessments along with a sample assessment for use by GEM fellowship programs seeking to create their own customized assessments. CONCLUSION: There are currently no widely used assessment frameworks for GEM fellowship training. The working group made recommendations for developing standardized assessments aligned with competencies defined by the programs, that characterize goals and objectives of training, and document progress of trainees towards achieving those goals. Frameworks used should include perspectives of multiple stakeholders including partners in other countries where trainees conduct field work. Future work may evaluate the usability, validity and reliability of assessment frameworks in GEM fellowship training.

National Spinal Cord Injury Registry of Iran (NSCIR-IR) - a critical appraisal of its strengths and weaknesses.

The National Spinal Cord Injury Registry of Iran (NSCIR-IR) is a not-for-profit, hospital-based, and prospective observational registry that appraises the quality of care, long-term outcomes and the personal and psychological burden of traumatic spinal cord injury in Iran. Benchmarking validity in every registry includes rigorous attention to data quality. Data quality assurance is essential for any registry to make sure that correct patients are being enrolled and that the data being collected are valid. We reviewed strengths and weaknesses of the NSCIR-IR while considering the methodological guidelines and recommendations for efficient and rational governance of patient registries. In summary, the steering committee, funded and maintained by the Ministry of Health and Medical Education of Iran, the international collaborations, continued staff training, suitable data quality, and the ethical approval are considered to be the strengths of the registry, while limited human and financial resources, poor interoperability with other health systems, and time-consuming processes are among its main weaknesses.

Planning for the future: Modelling daily emergency department presentations in an Australian capital city.

OBJECTIVE: To describe and model a decade of ED presentations in metropolitan Melbourne, Australia, from July 2000 to June 2010 and to validate the model of ED presentations by testing the model's performance in forecasting the subsequent 2 year period of daily presentations, from July 2010 to June 2012. METHODS: Retrospective analyses of prospectively collected data sourced from the Victorian Emergency Minimum Dataset were performed and included 13 public hospitals. Time series modelling involved unobserved components modelling and forward selection of variables using incidence rate ratios. Forecasting with the model and validation were performed using the 2 year period up to June 2012. Model performance was calculated using the mean average percentage error. RESULTS: A total of 7 031 242 patient presentations occurred to the sample metropolitan EDs in the 12 year study period. An absolute increase in mean daily ED presentations of 81.3% was observed. Presentations increased on Sunday and Monday incidence rate ratio of 1.10 (95% CI 1.08-1.11, P < 0.05). No monthly or seasonal pattern was evident. Public holidays were associated with increased presentations, incidence rate ratio of 1.11 (95% CI 1.08-1.15, P < 0.05). The model with the best goodness-of-fit and Wald χ2 value included Sunday-Monday (vs Tuesday-Saturday), public holidays, the trend of gradual increase over time and a stochastic (random white noise) cycle. The mean average percentage error for the 2 year forecast period was 3.6%. CONCLUSION: We have produced and validated a model for predicting daily ED presentations across a major city. Even though ED presentations are multifactorial, city-wide daily presentations are predictable and explained by a small number of variables. The model will have implications for future health planning.

Impact of trauma system structure on injury outcomes: a systematic review protocol.

BACKGROUND: Injury represents one of the greatest public health challenges of our time with over 5 million deaths and 100 million people temporarily or permanently disabled every year worldwide. The effectiveness of trauma systems in decreasing injury mortality and morbidity has been well demonstrated. However, the organisation of trauma care varies significantly across trauma systems and we know little about which components of trauma systems contribute to their effectiveness. The objective of the study described in this protocol is to systematically review evidence of the impact of trauma system components on clinically significant outcomes including mortality, function and disability, quality of life, and resource utilization. METHODS: We will perform a systematic review of studies evaluating the association between at least one trauma system component (e.g. accreditation by a central agency, interfacility transfer agreements) and at least one injury outcome (e.g. mortality, disability, resource use). We will search MEDLINE, EMBASE, COCHRANE central, and BIOSIS/Web of Knowledge databases, thesis holdings, key injury organisation websites and conference proceedings for eligible studies. Pairs of independent reviewers will evaluate studies for eligibility and extract data from included articles. Methodological quality will be evaluated using elements of the ROBINS-I tool and the Cochrane risk of bias tool for non-randomized and randomized studies, respectively. Strength of evidence will be evaluated using the GRADE tool. DISCUSSION: We expect to advance knowledge on the components of trauma systems that contribute to their effectiveness. This may lead to recommendations on trauma system structure that will help policy-makers make informed decisions as to where resources should be focused. The review may also lead to specific recommendations for future research efforts. SYSTEMATIC REVIEW REGISTRATION: This protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 28-06-2016.

Development of a productive research culture in emergency medicine: Report of the outcomes of a research forum.

In recent years, the Australasian College for Emergency Medicine (ACEM) has increasingly focused on the need for high-quality research in emergency medicine (EM). One important initiative was the establishment of the ACEM Foundation, which among other responsibilities, is required to support clinical research through the provision of research funding and other measures. In February 2015, the Foundation held a Research Forum that was attended by the leading EM researchers from Australasia. The Forum aimed to determine how a productive research culture could be developed within the ACEM. Nine key objectives were determined including that research should be a core business of the ACEM and a core activity of the EM workforce, and that EM research should be sustainable and adequately supported. This report describes the background and conduct of the Forum, its recommendations and the way in which they could be implemented.
