Global injury morbidity and mortality from 1990 to 2017: results from the Global Burden of Disease Study 2017

Unintentional Injuries Requiring Medical Attention in Low-Income and Middle-Income Countries: Evidence from Nationally Representative surveys in 12 Countries

BACKGROUND

Despite a high burden of injuries in low-income and middle-income countries (LMICs), a lack of empirical evidence on mechanism, location, and distribution of unintentional injuries requiring medical attention (hereafter injuries) hinders informed health system policy development.

METHODS

Using individual-level data from nationally representative surveys conducted in LMICs between 2014-2019, we describe the weighted annual prevalence of non-fatal injuries, their mechanisms, environments in which they occur, and characteristics of people injured, in individuals aged 15-64 years. Multivariable logistic regression models were estimated to evaluate associations of injuries with individual-level characteristics.

RESULTS

We included data on 47,747 participants from 12 LMICs in four WHO regions. The weighted prevalence of non-fatal injuries in the past year was 6.8% (95% CI: 6.3%-7.2%); men suffered a greater prevalence of injuries than women (8.3% [95% CI 7.6%-9.0%] vs. 5.4% [95% CI 5.0%-5.9%], respectively). In the multivariable logistic regression, the odds of having any injury were lower among females and married people and higher among individuals with some primary education. Prevalence of non-road traffic collision injuries was almost threefold that of road traffic collision (RTC) injuries: 5.6% (5.2%-6.0%) vs. 1.7% (1.5%-2.0%). When considering non-RTC injuries, falls were the most common mechanism (47.0%, 95% CI 44.0%-50.1%), and homes were the most common location (38.1%, 95% CI 34.9%-41.4%), followed by road (17.9%, 95% CI 15.7%-20.4%), and workplace (17.4%, 95% CI 15.2%-19.8%). The largest proportion (23.2%, [95% CI 20.6%-25.9%]) of non-RTC injuries happened to women at home.

CONCLUSION

Non-RTC injuries, in particular falls, predominate in this population. This highlights a neglected side of injuries, many of which happen at home to women, whereas global attention tends to focus on RTCs. Data on all mechanisms of injuries and care-seeking behaviour after injuries are required for health system planning.

Burden of falls in China, 1992-2021 and projections to 2030: a systematic analysis for the global burden of disease study 2021

Background

The escalating burden of falls in China necessitates a detailed examination to elucidate its dynamics and trends. Using data from the Global Burden of Disease Study (GBD) 2021, this research assessed the burden of falls in China.

Methods

Data from GBD 2021 were analyzed using Joinpoint regression to identify long-term trends. The impact of mortality and disability-adjusted life years (DALYs) rate for falls was investigated through the age-period-cohort model. Additionally, a decomposition analysis was performed to ascertain the distinct impacts of population growth, aging, and epidemiological changes on the burden of falls from 1992 to 2021. Furthermore, this study employed both the BAPC and Nordpred models to project future burdens of falls.

Results

From 1992 to 2021 in China, the age-standardized rates of falls showed divergent trends. Prevalence and incidence rates increased, while mortality rates generally decreased. Males consistently exhibited higher rates than females. The rates of prevalence, incidence, and mortality exhibit a sharp increase beyond the age of 75 in 2021. Decomposition analysis identified aging as the primary driver of increased prevalence and mortality, particularly in females. Joinpoint regression analysis revealed fluctuating trends in prevalence and incidence with periods of increase and decline, and a general decrease in mortality except during brief intervals. DALYs and years of life lost (YLLs) rates generally decreased, with intervals of stabilization and minor increases, while years lived with disability (YLDs) showed significant fluctuations. By 2030, the projected DALYs rate for falls is expected to rise to approximately 547.4 per 100,000. Fractures of the lower extremity predominated as the leading cause of disability post-fall, with hip fractures increasingly contributing to disability among the older adult. Additionally, from 1992 to 2021, the population attributable fraction (PAF) of low bone mineral density for DALYs due to falls increased to 23.2%, with the PAF reaching 33.3% among women in 2021.

Conclusion

Falls continue to significantly burden public health in China. Our findings highlight the urgent need to develop targeted prevention and intervention strategies that cater to the country's unique demographic characteristics, aiming to mitigate the growing public health impact of falls.

Analysis and approach to renal trauma: A five-year experience at a level I trauma centre in north India

PURPOSE

Renal trauma constitutes 0.5% - 5% of all trauma patients, and 10% - 20% of abdominal trauma. It is the most commonly injured organ in the genitourinary tract. Road traffic crash (RTC) is the most common cause. In recent years due to the advances in radiological imaging and endovascular techniques, there has been an increase in the nonoperative management of renal trauma. We investigated a large trauma cohort at a level I trauma centre to evaluate patients' demographics with renal trauma, their management, and the outcomes.

METHODS

This was a retrospective analysis of the prospectively collected data of renal trauma patients managed from January 2016 to December 2020. Patients who visited the level I trauma centre in north India with renal trauma were included in this study. Patients who were dead on arrival in the emergency department were excluded. Demographics, mechanism of injury, presence of hemorrhagic shock, associated injuries, complications, length of hospital stay (LOS), discharge, and mortality were recorded. The data were entered in Microsoft Excel 365 and analysed using SPSS version 21.

RESULTS

This study collected data from 303 renal trauma patients. Males constituted 86.5% of the patients. Most patients were young, aged from 20 - 40 years. Blunt renal trauma was the predominant mode of injury (n = 270, 89.1%). RTCs (n = 190, 62.7%) and falls from height (n = 65, 21.4%) were the 2 most common mechanisms of injury. Focused assessment with sonography in trauma was positive in 68.4% of patients. Grade III (grading by the American Association for the Surgery of Trauma) renal trauma (30.4%) was the most common grade in our study. The liver (n = 104, 34.3%) and splenic trauma (n = 96, 31.7%) were the most commonly associated injuries. Of the 303 patients, 260 (85.8%) were managed nonoperatively. The mean (SD) of the patients' LOS was 12.5 (6.5) days. There were 25 (8.3%) mortalities during the study period and all of them had associated other injuries. The comparison of LOS of isolated renal trauma group and renal trauma with associated injuries group was not statistically significant (p = 0.322). All the patients who died during the study period had renal trauma with associated other organ injuries. None of the patients with isolated renal trauma died during the study. The outcome comparison between both groups was not statistically significant (p = 0.110).

CONCLUSION

Renal trauma predominantly occurs in young males, especially due to RTCs followed by fall from height. Focused assessment with sonography in trauma is not reliable in detecting renal injuries, other diagnostic tools such as contrast enhanced computed tomography torso should be considered in diagnosing and grading these injuries. Renal trauma usually does not occur in isolation. Majority are associated with other abdominal and extra abdominal injuries. Most of the times these injuries can be managed nonoperatively, which can achieve a low mortality. The patients who required surgery had high mortality as compared to patients who managed nonoperatively. These patients who required surgery had either severe renal or extra renal trauma and were in hemorrhagic shock. Renal trauma from this large cohort may contribute to improving the quality of care for patients with renal trauma by obtaining knowledge about the patient's characteristics, management, and outcomes.

Assessment of Long-Term Outcomes of Lower Limb Fractures Managed by Non-orthopaedic Specialist Surgeons in Rural Rwanda: A Pilot Feasibility Study

Introduction  Sub-Saharan Africa is disproportionately affected by injuries, and short-term morbidity and mortality are high in this context. Lower limb fractures (LLFs) are a common type of injury that can lead to severe disability with extensive negative social and economic consequences. However, little is known about the long-term outcomes of LLFs in sub-Saharan Africa. In this pilot study, we describe the feasibility of assessing epidemiological patterns of LLFs, the state of care, and long-term outcomes in rural Rwanda.  Methods  This study was conducted from July to December 2021. It consists of retrospective data collection from hospital charts and a cross-sectional, phone-based follow-up. Functional outcomes were assessed using the World Health Organization Disability Assessment Schedule (WHODAS; World Health Organization, Geneva, Switzerland) 2.0, and health-related quality of life (QoL) was assessed using a 36-Item Short Form Health Survey questionnaire (SF-36).  Results  Eighteen patients were included in the study, of which the majority were males (n=11, 61%), young adults (mean age 29, standard deviation (SD) 25), and without any previous comorbidities (n=16, 89%). Most patients had a single fracture, although nearly one-third presented with multi-trauma (n=5, 28%). The most common injury cause was falls (n=10, 56%). Fractures were most common in the femur/hip (n=10, 56%), and most fractures were closed (n=14, 78%) and non-comminuted (n=9, 50%). Disability was described as high, with a total mean WHODAS summary score of 80 (SD 29), whereas health-related QoL varied across the SF-36 domains, with "general health" being the lowest rated domain with a mean score of 30 (SD 25).  Conclusion  This study highlights the challenges of long-term follow-up after LLFs in a rural, low-resource setting but demonstrates that such a study is feasible if planned with contextual considerations. Self-perceived disability is high, and health-related QoL is low at long-term follow-up, which should be viewed in light of the fact that it primarily affects a young, previously healthy population.

Management of Systemic Anti-psoriatic Drugs in Psoriasis Patients with Concurrent Paraplegia or Tetraplegia: Insights From a 6-Year Multicenter, Retrospective Observational Study

INTRODUCTION

Patients with psoriasis (PsO) and permanent spinal cord injuries (SCI) resulting in paraplegia and tetraplegia may experience a higher rate of infections compared to patients with PsO without SCI. It can result in further challenges for therapeutic management with immunosuppressants (biological and non-biological treatments). Thus,  we aimed to evaluate the rate of infections in patients with PsO and SCI treated with systemic immunosuppressants.

METHODS

This multicenter, retrospective observational study enrolled patients with PsO and traumatic SCI undergoing systemic immunosuppressive treatments for at least 5 years. All patients were evaluated by experienced, board-certified dermatologists and neurologists. Demographic and clinical data were collected.

RESULTS

We enrolled 23 patients with SCI (16 with paraplegia and 7 with tetraplegia) treated with methotrexate (MTX) and different biologics (tumor necrosis factor (TNF) inhibitors (i) and interleukin (IL)-17i/IL-23i). Globally, patients with SCI treated with MTX displayed higher rates of infection compared to those treated with biologics. Patients with paraplegia had lower rates of infection compared to patients with tetraplegia during anti-psoriatic therapies (p < 0.05). Those treated with TNFi had greater rates of infection than those treated with IL-17i/IL-23i (p < 0.001). Patients with psoriatic arthritis (PsA) experienced a significant diagnostic delay and clinical monitoring of PsA severity was challenging.

CONCLUSION

In patients with moderate-to-severe PsO and concurrent traumatic SCI, dermatologists should consider using IL-17i/IL-23i as first-line therapy.

Prospective multi-centre analysis of rural trauma team development training for medical trainees and traffic law enforcement professionals in Uganda: an interrupted time series study

BACKGROUND

Research shows that trauma team formation could potentially improve effectiveness of injury care in rural settings. The aim of this study was to determine the feasibility of rural trauma team training amongst medical trainees and traffic law enforcement professionals in Uganda.

METHODS

Prospective multi-centre interrupted time series analysis of an interventional training based on the 4th edition of rural trauma team development course of the American College of Surgeons. Trauma related multiple choice questions (MCQs), and trauma non-technical skills were assessed pre-and post-training between September 2019- August 2023. Acceptability of the training for promulgation to other rural regions and its relevance to participants' work needs were evaluated on 5- and 3-point Likert scales respectively. The median MCQ scores (IQR) were compared before and after training at 95% CI, regarding p < 0.05 as statistically significant. Triangulation with open-ended questions was obtained. Time series regression models were applied to test for autocorrelation in performance using Stata 15.0. Ethical approval was obtained from Uganda National Council for Science and Technology (Ref: SS 5082).

RESULTS

A total of 500 participants including: 66 (13.2%) traffic police officers, 30 (6.0%) intern doctors, 140 (28.0%) fifth year and 264 (52.8%) third-year medical students were trained. Among the 434 medical trainees who completed the trauma-based MCQ assessment, the median pre- and post-test scores were 60%, IQR (50-65) and 80%, IQR (70-85) respectively. Overall, the mean difference between pre- and post-test scores was statistically significant (z = 16.7%, P|z|=<0.0001). Most participants strongly agreed to promulgate 389 (77.8%), relevance to their educational 405 (81.0%), and work needs 399 (79.8%). Each of the course components was rated above 76.0% as being very relevant. There was an overall increment in median (IQR) trauma-nontechnical skills team performance scores from 12 (9-14) to 17 (15-20) after the training (p < 0.001), with police teams advancing from 9.5 (6.0-12.5) to 19.5 (17.0-21.5) (p < 0.001).

CONCLUSION

This study demonstrates that rural trauma team development training had a positive effect on the test scores of course participants. The training is feasible, highly acceptable and regarded as relevant amongst medical trainees and traffic law enforcement professionals who provide first-aid to trauma patients in resource-limited settings. The findings could inform the design of future trauma teams in rural communities.

Economic loss attributable to premature deaths and morbidity among adolescents in India and its states

BACKGROUND

India's large youth population presents a significant opportunity to harness the demographic dividend. The disease burden in adolescents could be a hindrance for the future economy if not appropriately addressed.

METHODS

We utilised the data on the number of adolescent deaths and attributable years lived with disability (morbidity) in every state of India as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021. We estimated the economic impact as the cost of lost output due to premature adolescent deaths and morbidity for every state of India in 2021, using an output-based method. The cost of lost output is reported in US Dollars (USD) and as a percentage of Gross Domestic Product (GDP) for all diseases/conditions together, and separately for communicable diseases (CDs), non-communicable diseases (NCDs), and injuries.

RESULTS

The lost output from premature deaths and morbidity attributable to adolescents was USD 9.87 (95% CI 9.04-10.71) and USD 28.13 (95% CI 20.53-37.71) billion respectively, in India in 2021. The total economic loss of USD 38.01 billion (95% CI 29.57-48.41) was 1.30% (1.01-1.65) of India's GDP. The total economic loss as a percentage of the state's GDP varied 3.42 times between the states in 2021, ranging from 2.43% in Bihar to 0.71% in Sikkim. The total economic loss due to CDs, NCDs, and injuries was estimated at 0.45%, 0.69% and 0.16% of India's GDP in 2021, with significant variations across the states.

CONCLUSIONS

Strengthening the Indian Adolescent Health Strategy to address the diseases/ conditions contributing most to the total economic loss is needed to facilitate substantial avoidance of the high economic losses attributable to adolescent premature deaths and morbidity in India.

Incidence and prevalence of traumatic and non-traumatic wounds and burns and access to wound care in Sierra Leone; data from a nationwide household survey (PRESSCO) 2020

Objectives

This wound section of the PREvalence Study on Surgical COnditions (PRESSCO) determines the incidence and prevalence of wounds and burns in Sierra Leone. It further describes access to wound care and wound-related healthcare-seeking behaviour.

Methods

Between October 2019 and March 2020, a nationwide cross-sectional household survey was performed. The survey was based on Surgeons OverSeas Assessment of Surgical Need (SOSAS). Additional questions relating to wounds and burns were added. Following randomization, 25 households in 75 clusters were sampled. Severe wounds were clinically examined.

Results

Of the 3600 individuals included, 143 had developed 151 wounds, including burns (15.2 %) during the year preceding the interview (incidence 4.2 %). A total of 77 people had 83 wounds and burns at the time of the survey (prevalence 2.3 %), of which 23 were severe (prevalence 0.6 %). Burn incidence and prevalence were 0.6 % and 0.1 %, respectively. Most wounds were on extremities (73.5 %), often resulting from cuts (32.8 %), falls (22.4 %), or road traffic accidents (RTA; 16.4 %). Risk factors for developing a wound were male sex (p = 0.004), older age (p = 0.037) and smoking (p = 0.001). Severe wounds had a median duration of 18 months. For 70.2 % of wounds, care at a health facility was sought. Only 49.9 % of households reported financial capacity to visit a secondary health facility. For 56 (37.1 %) of wounds, the desired care was not obtainable. An estimated 44,000 (95 % CI 29,760-67,410) people in Sierra Leone suffer from a severe wound. An estimated 11,000 (95 % CI 6,416-18,268) annual deaths occur due to wounds, predominantly due to RTA's (66.7 %) and accidental injuries (20.0 %).

Conclusions

Wounds and burns account for an extensive burden on the health and economics of the individual, the household, and the Sierra Leonean society. For over one-third of wounds, the desired surgical care was not obtainable.

Damage control resuscitation: how it's done and where we can improve. A view of the Brazilian reality according to trauma professionals

INTRODUCTION

Hemorrhage is the leading cause of preventable deaths in trauma patients, resulting in 1.5 million deaths annually worldwide. Traditional trauma assessment follows the ABC (airway, breathing, circulation) sequence; evidence suggests the CAB (circulation, airway, breathing) approach to maintain perfusion and prevent hypotension. Damage Control Resuscitation (DCR), derived from military protocols, focuses on early hemorrhage control and volume replacement to combat the "diamond of death" (hypothermia, hypocalcemia, acidosis, coagulopathy). This study evaluates the implementation of DCR protocols in Brazilian trauma centers, hypothesizing sub-optimal resuscitation due to high costs of necessary materials and equipment.

METHODS

In 2024, an electronic survey was conducted among Brazilian Trauma Society members to assess DCR practices. The survey, completed by 121 participants, included demographic data and expertise in DCR.

RESULTS

All 27 Brazilian states were represented in the study. Of the respondents, 47.9% reported the availability of Massive Transfusion Protocol (MTP) at their hospitals, and only 18.2% utilized whole blood. Permissive hypotension was practiced by 84.3%, except in traumatic brain injury cases. The use of tranexamic acid was high (96.7%), but TEG/ROTEM was used by only 5%. For hemorrhage control, tourniquets and resuscitative thoracotomy were commonly available, but REBOA was rarely accessible (0.8%).

CONCLUSION

Among the centers represented herein, the results highlight several inconsistencies in DCR and MTP implementation across Brazilian trauma centers, primarily due to resource constraints. The findings suggest a need for improved infrastructure and adherence to updated protocols to enhance trauma care and patient outcomes.

The incidence and influencing factors of recent suicide attempts in major depressive disorder patients comorbid with moderate-to-severe anxiety: a large-scale cross-sectional study

BACKGROUND

Major depressive disorder (MDD) is a recurrent and persistent mental illness. However, there is a lack of research that distinguishes the severity of comorbid anxiety disorders in MDD, and insufficient evidence exists regarding the prevalence of MDD patients with comorbid moderate-to-severe anxiety in the Chinese population.

METHODS

The study included 1718 MDD patients (894 with moderate-to-severe anxiety symptoms and 824 without moderate-to-severe anxiety symptoms). Clinical symptoms and development were assessed using the Hamilton Depression Rating Scale-17 (HAMD-17), Hamilton Anxiety Rating Scale-14 (HAMA-14), Positive and Negative Syndrome Scale (PANSS), and Clinical Global Impression (CGI). The blood pressure and thyroid hormone levels were measured.

RESULTS

We found that the incidence of MDD patients with moderate-to-severe anxiety symptoms was 52.04%. The prevalence of recent suicide attempts in MDD comorbid moderate-to-severe anxiety patients was 31.8%, which was 4.24 times higher than that in patients without moderate-to-severe anxiety. Additionally, suicide attempters had elevated levels of thyroid stimulating hormone (TSH), anti-thyroglobulin (TgAb), thyroid peroxidases antibody (TPOAb), systolic blood pressure (SBP), and diastolic blood pressure (DBP) compared to non-suicide attempters. We further identified CGI score, TSH, TPOAb, and DBP as influential factors for recent suicide attempts in MDD individuals who had moderate-to-severe anxiety symptoms. These indexes could distinguish between suicide attempts and non-suicide attempts in MDD patients with moderate-to-severe anxiety symptoms.

CONCLUSIONS

Our findings mainly indicated a high prevalence of recent suicide attempts in MDD patients with moderate-to-severe anxiety. Several clinical correlates, thyroid hormones, and blood pressure might contribute to recent suicide attempts in MDD patients with moderate-to-severe anxiety symptoms.

Analysis and comparison of the trends in burden of spinal cord injury in China and worldwide from 1990 to 2021: an analysis of the global burden of disease study 2021

Background

Spinal cord injury (SCI) is a globally prevalent neurological condition, often resulting in motor, sensory, and autonomic dysfunctions that lead to permanent disability. However, outdated epidemiological data hinder the development and implementation of effective public health policies. This study aimed to examine and compare trends in the burden of spinal cord injury-specifically incidence, prevalence, and years lived with disability (YLD)-in China and worldwide from 1990 to 2021, and to project these trends over the next 15 years.

Methods

This study analyzed the characteristics of the SCI burden in China and globally, examining changes in incidence, prevalence, and years lived with disability (YLD) using open data from the Global Burden of Disease database covering 1990 to 2021. Additionally, Joinpoint and age-period-cohort (APC) analyses were conducted to provide insights into the epidemiological characteristics of the SCI burden. The autoregressive integrated moving average (ARIMA) model was then applied to project SCI trends for the next 15 years.

Results

In 2021, the prevalence and incidence of SCI in China reached 2,766,277 and 99,363 cases, respectively, marking increases of 63.27 and 43.27% since 1990. From 1990 to 2021, the age-standardized prevalence rate (ASPR) of SCI decreased significantly, with an estimated annual percentage change (EAPC) of -0.34 (95% CI: -0.60 to-0.07). At the gender level, SCI prevalence and incidence were higher in men than in women. Joinpoint analysis revealed a significant decrease in the APC of the age-standardized incidence rate (ASIR) from 1990 to 2011 (APC = -0.98, p < 0.05), followed by a notable increase from 2011 to 2021 (APC = 2.05, p < 0.05). For ASPR, a significant decrease occurred from 2001 to 2005 (APC = -4.80, p < 0.05), while subsequent periods showed an increasing trend, particularly between 2010 and 2018 (APC = 1.43, p < 0.05) and 2018-2021 (APC = 2.84, p < 0.05). In terms of age-standardized YLD rates (ASYR), China experienced an overall downward trend from 1990 to 2010 (APC = -0.56 for 1990-2001; -5.97 for 2001-2005; -1.01 for 2005-2010, p < 0.05), followed by a slight upward trend post-2010, with fluctuations from 2010 and 2018 (APC = 0.88) and 2018-2021 (APC = 2.49, p < 0.05). Age-period-cohort analysis showed that the risk of SCI incidence increased with age in China, though both period and cohort effects demonstrated a significant downward trend. Projections indicate that by 2036, the ASIR and ASPR for SCI in China will reach 6 and 146 cases per 100,000 people, respectively.

Conclusion

The number and burden of SCI in China and globally have increased in the past. Among them, men and older people are more likely to develop SCI than women and younger people. Although the ASPR and ASIR for SCI are predicted to show a downward trend over the next 15 years, policy makers should continue to consider interventions to minimize the risk.

Global, regional, and national burdens of mild traumatic brain injuries from 1990 to 2019: findings from the Global Burden of Disease Study 2019 - a cross-sectional study

BACKGROUND

The objective of this study was to utilize data from the Global Burden of Disease Study (GBD) 2019 to estimate the patterns and prevalence of mild traumatic brain injury (mTBI) from 1990 to 2019, with the intention of informing the development of efficacious intervention strategies.

MATERIAL AND METHODS

Data from the GBD 2019 were examined to determine the prevalence, incidence, and rates of years lived with disability (YLDs) associated with mTBI across global geographic populations from 1990 to 2019. To assess temporal patterns, estimated annual percentage changes (EAPCs) and age-standardized rates were computed. Additionally, an age-period-cohort model (APC model) framework was employed to analyze potential trends in incidence based on age, period, and birth cohort.

RESULTS

In 2019, there were a total of 12 268.5 thousand incident cases (95% uncertainty interval [UI] 992.66-1602.07), 11 482.5 thousand prevalent cases (95% UI 107.59-123.52), and 1366.9 thousand YLDs (95% UI 96.36-183.35) of mTBI worldwide. The age-standardized rates (ASRs) of incidence, prevalence, and YLDs exhibited a decline from 1990 to 2019. Across all age groups, males had higher prevalence, incidence, and YLD rates. Furthermore, middle-aged and elderly adults experienced a greater disease burden. The primary causes of the global mTBI burden in 2019 were falls and road injuries. According to the APC model, the age effect trend exhibited a similar pattern across individual sociodemographic index (SDI) groups, characterized by an initial increase, followed by a decrease and a subsequent increase. Regarding the period effect, each SDI group demonstrated variation, with the middle SDI group notably displaying a consistent increase. Furthermore, in terms of the birth effect, the middle-SDI group experienced the most substantial and continuous increase.

CONCLUSION

The global incident cases and prevalent cases of mTBI increased significantly from 1990 to 2019, with a heavier burden observed in males, older adults, and in low SDI such as Afghanistan. More efforts are needed in the prevention and management of mTBI, such as reducing the incidence of falls among older people and building safer road transport facilities to reduce the burden of mTBI.

Using Large Language Models to Extract Core Injury Information From Emergency Department Notes

BACKGROUND

Injuries pose a significant global health challenge due to their high incidence and mortality rates. Although injury surveillance is essential for prevention, it is resource-intensive. This study aimed to develop and validate locally deployable large language models (LLMs) to extract core injury-related information from Emergency Department (ED) clinical notes.

METHODS

We conducted a diagnostic study using retrospectively collected data from January 2014 to December 2020 from two urban academic tertiary hospitals. One served as the derivation cohort and the other as the external test cohort. Adult patients presenting to the ED with injury-related complaints were included. Primary outcomes included classification accuracies for information extraction tasks related to injury mechanism, place of occurrence, activity, intent, and severity. We fine-tuned a single generalizable Llama-2 model and five distinct Bidirectional Encoder Representations from Transformers (BERT) models for each task to extract information from initial ED physician notes. The Llama-2 model was able to perform different tasks by modifying the instruction prompt. Data recorded in injury registries provided the gold standard labels. Model performance was assessed using accuracy and macro-average F1 scores.

RESULTS

The derivation and external test cohorts comprised 36,346 and 32,232 patients, respectively. In the derivation cohort's test set, the Llama-2 model achieved accuracies (95% confidence intervals) of 0.899 (0.889-0.909) for injury mechanism, 0.774 (0.760-0.789) for place of occurrence, 0.679 (0.665-0.694) for activity, 0.972 (0.967-0.977) for intent, and 0.935 (0.926-0.943) for severity. The Llama-2 model outperformed the BERT models in accuracy and macro-average F1 scores across all tasks in both cohorts. Imposing constraints on the Llama-2 model to avoid uncertain predictions further improved its accuracy.

CONCLUSION

Locally deployable LLMs, trained to extract core injury-related information from free-text ED clinical notes, demonstrated good performance. Generative LLMs can serve as versatile solutions for various injury-related information extraction tasks.

Animal models of neuropathic pain

Animal models continue to be crucial to developing our understanding of the molecular, cellular, and neurophysiological mechanisms that lead to neuropathic pain. The overwhelming majority of animal studies use rodent models, ranging from surgical and trauma-induced models to those induced by metabolic diseases, genetic mutations, viruses, neurotoxic drugs, and cancer. We discuss the clinical relevance of the available models and the pain behavior tests commonly used as outcome measures. Finally, we summarize the refinements that have been proposed to improve the ability of animal model studies to predict clinical efficacy.

Insights into epidemiological trends of severe chest injuries: an analysis of age, period, and cohort from 1990 to 2019 using the Global Burden of Disease study 2019

BACKGROUND

This study assessed the global trends and burden of severe chest injury, including rib fractures, lung contusions, and heart injuries from 1990 to 2019. Herein, we predicted the burden patterns and temporal trends of severe chest injuries to provide epidemiological evidence globally and in China.

METHODS

In our analysis, the age-standardized incidence rate (ASIR), prevalence rate (ASPR), and years lived with disability rate (ASYR) of severe chest injury were analyzed by gender, age, sociodemographic index, and geographical region between 1990 and 2019 using data from the Global Burden of Disease study 2019. Trends were depicted by calculating the estimated annual percentage changes (EAPCs). The impact of age, period, and cohort factors was assessed using an Age-Period-Cohort model. Autoregressive integrated moving average (ARIMA) model was employed to predict severe chest injury trends from 2020 to 2050.

RESULTS

In 2019, the global number of severe chest injury cases reached 7.95 million, with the highest incidence rate observed in Central Europe (209.61). Afghanistan had the highest ASIRs at 277.52, while North Korea had the lowest ASIRs at 41.02. From 1990 to 2019, the Syrian Arab Republic saw significant increases in ASIR, ASPR, and ASYR, with EAPCs of 10.4%, 9.31%, and 10.3%, respectively. Burundi experienced a decrease in ASIR with an EAPC of - 6.85% (95% confidence interval [CI] - 11.11, - 2.37), while Liberia's ASPR and ASYR declined with EAPCs of - 3.22% (95% CI - 4.73, - 1.69) and - 5.67% (95% CI - 8.00, - 3.28), respectively. Falls and road injuries remained the most common causes. The relative risk of severe chest injury by age, period, and cohort demonstrated a complex effect globally and in China. The ARIMA model forecasted a steady increase in global numbers from 2020 to 2050, while in China, it forecasted an increase in incidence, a decrease in ASIR and ASYR, and an increase in ASPR.

CONCLUSIONS

This study provides a groundbreaking analysis of global severe chest injury, shedding light on its measures and impact. These findings highlight the need for timely, specialized care and addressing regional disparities to mitigate the severe chest injury burden.

Comparing NEWS2, TRISS, and RTS in predicting mortality rate in trauma patients based on prehospital data set: a diagnostic study

BACKGROUND

In the recent years, National Early Warning Score2 (NEWS2) is utilized to predict early on, the worsening of clinical status in patients. To this date the predictive accuracy of National Early Warning Score (NEWS2), Revised Trauma Score (RTS), and Trauma and injury severity score (TRISS) regarding the trauma patients' mortality rate have not been compared. Therefore, the objective of this study is comparing NEWS2, TRISS, and RTS in predicting mortality rate in trauma patients based on prehospital data set.

METHODS

This cross-sectional retrospective diagnostic study performed on 6905 trauma patients, of which 4191 were found eligible, referred to the largest trauma center in southern Iran, Shiraz, during 2022-2023 based on their prehospital data set in order to compare the prognostic power of NEWS2, RTS, and TRISS in predicting in-hospital mortality rate. Patients are divided into deceased and survived groups. Demographic data, vital signs, and GCS were obtained from the patients and scoring systems were calculated and compared between the two groups. TRISS and ISS are calculated with in-hospital data set; others are based on prehospital data set.

RESULTS

A total of 129 patients have deceased. Age, cause of injury, length of hospital stay, SBP, RR, HR, temperature, SpO2, and GCS were associated with mortality (p-value < 0.001). TRISS and RTS had the highest sensitivity and specificity respectively (77.52, CI 95% [69.3-84.4] and 93.99, CI 95% [93.2-94.7]). TRISS had the highest area under the ROC curve (0.934) followed by NEWS2 (0.879), GCS (0.815), RTS (0.812), and ISS (0.774). TRISS and NEWS were superior to RTS, GCS, and ISS (p-value < 0.0001).

CONCLUSION

This novel study compares the accuracy of NEWS2, TRISS, and RTS scoring systems in predicting mortality rate based on prehospital data. The findings suggest that all the scoring systems can predict mortality, with TRISS being the most accurate of them, followed by NEWS2. Considering the time consumption and ease of use, NEWS2 seems to be accurate and quick in predicting mortality based on prehospital data set.

Exploring Diet-Based Treatments for Atrial Fibrillation: Patient Empowerment and Citizen Science as a Model for Quality-of-Life-Centered Solutions

Atrial fibrillation (AF) is the most common heart rhythm disorder in the Western world. Between the years 2010 and 2019, the global prevalence of AF rose from 33.5 million to 59 million, highlighting the importance of developing equitable treatments for patients. The disease is associated with symptoms such as palpitations, dizziness, fatigue, shortness of breath, and cognitive dysfunction. In addition, AF increases the risk of developing a stroke and heart failure. Despite new insights into risk factors that can lead to the development of AF, the success of current treatments is suboptimal. Numerous risk factors, such as hypertension, diabetes, and obesity, have been associated with the development and progression of AF. As these can be lifestyle-related risk factors, lifestyle modification may be a solution to reduce AF-related symptoms as well as episodes. Research results show that certain dietary changes can reduce AF and numerous risk factors for AF. Increasing attention is being given to Mediterranean and whole, plant-based eating patterns, which emphasize eating grains, legumes, vegetables, fruits, and nuts, while excluding most-or all-animal products. Hence, what are the beneficial aspects of a Mediterranean and plant-based diet which consists mainly of unprocessed foods? In the current review, we discuss the outcomes of diet-based treatments. Moreover, other diet-related treatments, brought up by patient initiatives, are highlighted. These patient-initiated studies include L-glutamine and electrolytes as options to manage AF. Also, we highlight the emerging importance of valuing patient needs and a quality-of-life-centered approach to medicine. As indicated by recent studies and patient experiences, citizen science can create inclusive solutions that lead to patient empowerment and a holistic approach for AF management.

The burden of injury among elderly individuals in China from 1990 to 2019: An analysis of data from the global burden of disease study 2019

Background

With the rapid ageing of the population, injuries are increasingly threatening the health of elderly individuals. A comprehensive evaluation of the injury burden is important for selecting and formulating strategies for injury prevention.

Objective

To evaluate the temporal trends of injury burden among elderly Chinese individuals aged 60 years and older.

Methods

Based on the results of the Global Burden of Disease Study 2019, the injury mortality, morbidity, and disability-adjusted life years (DALYs) of elderly individuals from 1990 to 2019 were estimated by age and sex. The autoregressive integrated moving average model was used to predict the injury burden in the next decade.

Results

In 2019, there were an estimated 304 373 deaths due to injuries in China, accounting for 3.55 % of all deaths. The main cause of injury-related death was unintentional injuries (67.28 deaths per 100 000), followed by transport injuries (30.44 deaths per 100 000). The standardized DALYs rate due to injuries among elderly individuals was 3488.54 DALYs per 100 000. In the past 30 years, the morbidity of injuries among elderly individuals in China has increased by 52.18 %. In 2030, we estimated that there will be 398 200 deaths of elderly individuals due to injury.

Conclusions

Over 21% of injury-related deaths among elderly individuals occurred in China. The injury burden among elderly individuals is high, and efforts are needed to inform injury prevention policies and adopt injury prevention strategies to reduce the injury burden and promote the health and well-being of elderly individuals.

Measuring the Prevalence, Treatment, and Associated Treatment Costs of Injury for Older Adults in India: Insights from the National Longitudinal Aging Study

This cross-sectional analysis of secondary data aimed to examine the injury prevalence, treatment, and associated healthcare expenditure among older adults in India. Longitudinal Aging Study India Wave 1 data for those aged 60+ years comprising sociodemographic characteristics and self-reported major injury, injury mechanism, falls and joint/bone fractures, treatment sought, and out-of-pocket expenditure (OOPE) were analyzed. Descriptive, relative risk, bivariate, and two-part regression model analyses were conducted. Fifteen percent of the 31,464 older adults surveyed had experienced a major injury, 13% a fall and 5% a bone/joint fracture. The risk of injury increased with age and income and was higher for urban residents and females. Seventy-eight percent of those who experienced injury sought medical treatment, 56% needing treatment for a serious fall and 3% undergoing surgery. Higher proportions of females than males required medical treatment for falls and injury-related surgery, yet on average, females were spending less than males for public or private hospital treatment. Injury-related OOPE increased with age and decreased with lower education. Scaling up injury prevention efforts specifically focused on older adults will be vital given the projected growth in the older adult population in India in coming years. Such efforts will prevent unnecessary health impacts and reduce health system utilization and associated individual and family economic burden.

Musculoskeletal system injuries in the Polish Territorial Defence Forces

BACKGROUND

Musculoskeletal system injuries (MSIs) are the major health problem of soldiers. The aim of this study was to assess the types of MSIs that occurred most frequently among soldiers and which parts of the body they generally affected.

METHODS

The study included 140 Territorial Army soldiers, both men and women, serving in the Polish Territorial Defence Forces (TDF). Times and frequency of MSIs were assessed using an original questionnaire available via a web-based platform, the TDF Information Portal and the Yammer network.

RESULTS

Among the participants, 42% reported MSIs, most often a single one (19%), incurred while doing military service. Damaged muscles and ligaments were the most common injuries in both groups (p>0.05). The knee joint was the main location of injuries for both sexes (24% in men vs 50% in women, p>0.05). Other parts of the body often affected by injuries were the shoulder joint (24%, p>0.05), head, spine, wrist, fingers, ankle and feet (19% each) in the male soldiers and the ankle (24%), spine (14%), head, chest, shoulder joint and foot (10% each) in the female soldiers. Injuries reoccurred with similar frequency in the female and male soldiers (43% vs 40%, p>0.05) and had the same location in both groups (43% vs 40%, respectively, p>0.05). Difficult terrain, too intensive military training and heavy loads were the main risk factors for MSIs in both groups (p>0.05).

CONCLUSIONS

More than half of all the participants (19% of the men and 33% of the women) reported at least one injury incurred during military service. Over 40% of all the study subjects had reinjuries. The males and females were similar in terms of the most common type and location of MSI. Occurrence of MSIs rarely required interruption in the military training/service.

Control of Haemorrhage in Orthopaedic Trauma

This paper aims to outline current practices and examine promising new advancements in the modern management of haemorrhage in orthopaedic trauma. Many prehospital and perioperative haemorrhage control strategies and techniques have been available to clinicians for multiple decades, yet our understanding and utilisation of these practices continues to be refined and optimised. There is a particular focus in this article on issues related to resuscitation and coagulation in trauma. We examine the complex mechanisms that lead to coagulopathy in trauma patients as well as the transformative effect tranexamic acid has had in limiting blood loss. We also explore some emerging technologies such as endovascular interventions and clot-stabilising dressings and devices that are likely to have a significant impact going forward.

The Role of Whole Blood Hemostatic Resuscitation in Bleeding Geriatric Trauma Patients

INTRODUCTION

Whole blood (WB) has recently gained increased popularity as an adjunct to the resuscitation of hemorrhaging civilian trauma patients. We aimed to assess the nationwide outcomes of using WB as an adjunct to component therapy (CT) versus CT alone in resuscitating geriatric trauma patients.

METHODS

We performed a 5-y (2017-2021) retrospective analysis of the Trauma Quality Improvement Program. We included geriatric (age, ≥65 y) trauma patients presenting with hemorrhagic shock (shock index >1) and requiring at least 4 units of packed red blood cells in 4 h. Patients with severe head injuries (head Abbreviated Injury Scale ≥3) and transferred patients were excluded. Patients were stratified into WB-CT versus CT only. Primary outcomes were 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications. Multivariable regression analysis was performed, adjusting for potential confounding factors.

RESULTS

A total of 1194 patients were identified, of which 141 (12%) received WB. The mean ± standard deviation age was 74 ± 7 y, 67.5% were male, and 83.4% had penetrating injuries. The median [interquartile range] Injury Severity Score was 19 [13-29], with no difference among study groups (P = 0.059). Overall, 6-h, 24-h, and in-hospital mortality were 16%, 23.1%, and 43.6%, respectively. On multivariable regression analysis, WB was independently associated with reduced 24-h (odds ratio, 0.62 [0.41-0.94]; P = 0.024), and in-hospital mortality (odds ratio, 0.60 [0.40-0.90]; P = 0.013), but not with major complications (odds ratio, 0.78 [0.53-1.15]; P = 0.207).

CONCLUSIONS

Transfusion of WB as an adjunct to CT is associated with improved early and overall mortality in geriatric trauma patients presenting with severe hemorrhage. The findings from this study are clinically important, as this is an essential first step in prioritizing the selection of WB resuscitation for geriatric trauma patients presenting with hemorrhagic shock.

Prediction of the burden of road traffic injuries in Iran by 2030: Prevalence, death, and disability-adjusted life years

PURPOSE

Road traffic accidents pose a global challenge with substantial human and economic costs. Iran experiences a high incidence of road traffic injuries, leading to a significant burden on society. This study aims to predict the future burden of road traffic injuries in Iran until 2030, providing valuable insights for policy-making and interventions to improve road safety and reduce the associated human and economic costs.

METHODS

This analytical study utilized time series models, specifically autoregressive integrated moving average (ARIMA) and artificial neural networks (ANNs), to predict the burden of road traffic accidents by analyzing past data to identify patterns and trends in Iran until 2030. The required data related to prevalence, death, and disability-adjusted life years (DALYs) rates were collected from the Institute for Health Metrics and Evaluation database and analyzed using R software and relevant modeling and statistical analysis packages.

RESULTS

Both prediction models, ARIMA and ANNs indicate that the prevalence rates (per 100,000) of all road traffic injuries, except for motorcyclist road injuries which have an almost flat trend, remaining at around 430, increase by 2030. Based on estimations of both models, the rates of death and DALYs due to motor vehicle and pedestrian road traffic injuries decrease. For motor vehicle road injuries, estimated trends decrease to approximately 520 DALYs and 10 deaths. Also, for pedestrian road injuries these rates reached approximately 300 DALYs and 6 deaths, according to the models. For cyclists and other road traffic injuries, the predicted DALY rates by the ANN model increase to almost 50 and 8, while predictions conducted by the ARIMA model show a static trend, remaining at 40 and approximately 6.5. Moreover, these rates for the prediction of death rate by the ANN model increased to 0.6 and 0.1, while predictions conducted by the ARIMA model show a static trend, remaining at 0.43 and 0.07. According to the ANN model, the predicted rates of DALY and death for motorcyclists decrease to 100 and approximately 2.7, respectively. On the other hand, predictions made by the ARIMA model show a static trend, with rates remaining at 200 and approximately 3.2, respectively.

CONCLUSION

The prevalence of road traffic injuries is predicted to increase, while the death and DALY rates of road traffic injuries show different patterns. Effective intervention programs and safety measures are necessary to prevent and reduce road traffic accidents. Different interventions should be designed and implemented specifically for different groups of pedestrians, cyclists, motorcyclists, and motor vehicle drivers.

The global burden of fracture-related infection: can we do better?

Fracture-related infection is a major complication related to musculoskeletal injuries that not only has important clinical consequences, but also a substantial socioeconomic impact. Although fracture-related infection is one of the oldest disease entities known to mankind, it has only recently been defined and, therefore, its global burden is still largely unknown. In this Personal View, we describe the origin of the term fracture-related infection, present the available data on its global impact, and discuss important aspects regarding its prevention and management that could lead to improved outcomes in both high-resource and low-resource settings. We also highlight the need for health-care systems to be adequately compensated for the high cost of human resources (trained staff) and well-equipped facilities required to adequately care for these complex patients. Our aim is to increase awareness among clinicians and policy makers that fracture-related infection is a disease entity that deserves prioritisation in terms of research, with the goal to standardise treatment and improve patient outcomes on a global scale.

Analyzing the trend of mortality due to traffic and nontraffic accidents: a study in the north of Iran

Background

Examining the raw and standardized mortality rates is the primary strategy for improving life expectancy and human health in society through identifying risk factors and dealing with the factors that cause them.

Objectives

This study examined the trend of mortalities due to traffic and nontraffic accidents.

Methods

This cross-sectional study examines the registered mortalities during the years 2016-2022 in the form of a census in the health department's death registration and classification system. Mortality was analyzed as raw and standardized mortality in each 100 000 population.

Results

Out of 18 265 deaths during 2016-2022, 1305 (7.15%) were related to accidents and incidents. The age-standardized total mortality rate in the first year was 32.9, and in the final year of the study, it was 33.3 per 100 000 people; although there are fluctuations, this trend is upward (P.trend=0.021). Also, the age-standardized traffic death rate in the first year is 19, and in the final year is 12 per 100 000 people; this decreasing trend was not statistically significant (P.trend=0.061). The incidence of age-standardized intentional nontraffic deaths was 1.7 in the first year of the study interval and 9.8 in the last year in 100 000 people, which showed an upward trend (P.trend<0.001).

Conclusion

In light of the generally increasing trend of accidents, especially nontraffic accidents, universal and well-rounded measures are necessary for safety matters and reducing mortality.

Post-injury long-term sickness absence and risk of disability pension: The role of socioeconomic status

INTRODUCTION

Previous research has identified low socioeconomic status (SES) as a risk factor for long-term sickness absence (LTSA) and disability pension (DP) following trauma. However, most studies lack information on medical diagnoses, limiting our understanding of the underlying factors. To address this gap, we retrieved information about diagnostic causes for receipt of welfare benefits to explore the role of SES in the transition from post-injury LTSA to permanent DP among the working population in Norway.

MATERIALS AND METHODS

We conducted a population-based cohort study of all Norwegian residents aged 25-59 years registered with a spell of LTSA due to injury commencing in the period 2000-2003. This cohort was followed through 2014 by linking information on receipt of welfare benefits with sociodemographic data from administrative registers. SES was defined as a composite measure of educational attainment and income level. We used flexible parametric survival models to estimate hazard ratios (HR) with 95 % confidence intervals (CI) for all-cause and diagnosis-specific DP according to SES, adjusting for sex, age, marital status, immigrant status and healthcare region of residence.

RESULTS

Of 53,937 adults with post-injury LTSA, 9,665 (18 %) transferred to DP during follow-up. The crude risk of DP was highest for LTSA spells due to poisoning and head injuries. Overall, individuals in the lowest SES category had twice the risk of DP compared to those in the highest SES category (HR = 2.25, 95 % CI 2.13-2.38). The difference by SES was greatest for LTSA due to poisoning and smallest for LTSA due to head injuries. A majority (75 %) of DP recipients had a non-injury diagnosis as the primary cause of DP. The socioeconomic gradient was more pronounced for non-injury causes of DP (HR = 2.47, 95 % CI 2.31-2.63) than for injury causes (HR = 1.73, 95 % CI 1.56-1.92) and was especially steep for DP due to musculoskeletal diseases and mental and behavioural disorders.

CONCLUSIONS

The relationship between SES and DP varied by both the type of injury that caused LTSA and the diagnosis used to grant DP, highlighting the importance of taking diagnostic information into account when investigating long-term consequences of injuries.

Torso hemorrhage: noncompressible? never say never

Since limb bleeding has been well managed by extremity tourniquets, the management of exsanguinating torso hemorrhage (TH) has become a hot issue both in military and civilian medicine. Conventional hemostatic techniques are ineffective for managing traumatic bleeding of organs and vessels within the torso due to the anatomical features. The designation of noncompressible torso hemorrhage (NCTH) marks a significant step in investigating the injury mechanisms and developing effective methods for bleeding control. Special tourniquets such as abdominal aortic and junctional tourniquet and SAM junctional tourniquet designed for NCTH have been approved by FDA for clinical use. Combat ready clamp and junctional emergency treatment tool also exhibit potential for external NCTH control. In addition, resuscitative endovascular balloon occlusion of the aorta (REBOA) further provides an endovascular solution to alleviate the challenges of NCTH treatment. Notably, NCTH cognitive surveys have revealed that medical staff have deficiencies in understanding relevant concepts and treatment abilities. The stereotypical interpretation of NCTH naming, particularly the term noncompressible, is the root cause of this issue. This review discusses the dynamic relationship between TH and NCTH by tracing the development of external NCTH control techniques. The authors propose to further subdivide the existing NCTH into compressible torso hemorrhage and NCTH' (noncompressible but REBOA controllable) based on whether hemostasis is available via external compression. Finally, due to the irreplaceability of special tourniquets during the prehospital stage, the authors emphasize the importance of a package program to improve the efficacy and safety of external NCTH control. This program includes the promotion of tourniquet redesign and hemostatic strategies, personnel reeducation, and complications prevention.

Rural trauma team development training amongst medical trainees and traffic law enforcement professionals in a low-income country: a protocol for a prospective multicenter interrupted time series

Background

Road traffic injuries and their resulting mortality disproportionately affect rural communities in low-middle-income countries (LMICs) due to limited human and infrastructural resources for postcrash care. Evidence from high-income countries show that trauma team development training could improve the efficiency, care, and outcome of injuries. A paucity of studies have evaluated the feasibility and applicability of this concept in resource constrained settings. The aim of this study protocol is to establish the feasibility of rural trauma team development and training in a cohort of medical trainees and traffic law enforcement professionals in Uganda.

Methods

Muticenter interrupted time series of prospective interventional trainings, using the rural trauma team development course (RTTDC) model of the American College of Surgeons. A team of surgeon consultants will execute the training. A prospective cohort of participants will complete a before and after training validated trauma related multiple choice questionnaire during September 2019-November 2023. The difference in mean prepost training percentage multiple choice questionnaire scores will be compared using ANOVA-test at 95% CI. Time series regression models will be used to test for autocorrelations in performance. Acceptability and relevance of the training will be assessed using 3 and 5-point-Likert scales. All analyses will be performed using Stata 15.0. Ethical approval was obtained from Research and Ethics Committee of Mbarara University of Science and Technology (Ref: MUREC 1/7, 05/05-19) and Uganda National Council for Science and Technology (Ref: SS 5082). Retrospective registration was accomplished with Research Registry (UIN: researchregistry9490).

Validity and reliability International Classification of Diseases-10 codes for all forms of injury: A systematic review

BACKGROUND

Intentional and unintentional injuries are a leading cause of death and disability globally. International Classification of Diseases (ICD), Tenth Revision (ICD-10) codes are used to classify injuries in administrative health data and are widely used for health care planning and delivery, research, and policy. However, a systematic review of their overall validity and reliability has not yet been done.

OBJECTIVE

To conduct a systematic review of the validity and reliability of external cause injury ICD-10 codes.

METHODS

MEDLINE, EMBASE, COCHRANE, and SCOPUS were searched (inception to April 2023) for validity and/or reliability studies of ICD-10 external cause injury codes in all countries for all ages. We examined all available data for external cause injuries and injuries related to specific body regions. Validity was defined by sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Reliability was defined by inter-rater reliability (IRR), measured by Krippendorff's alpha, Cohen's Kappa, and/or Fleiss' kappa.

RESULTS

Twenty-seven published studies from 2006 to 2023 were included. Across all injuries, the mean outcome values and ranges were sensitivity: 61.6% (35.5%-96.0%), specificity: 91.6% (85.8%-100%), PPV: 74.9% (58.6%-96.5%), NPV: 80.2% (44.6%-94.4%), Cohen's kappa: 0.672 (0.480-0.928), Krippendorff's alpha: 0.453, and Fleiss' kappa: 0.630. Poisoning and hand and wrist injuries had higher mean sensitivity (84.4% and 96.0%, respectively), while self-harm and spinal cord injuries were lower (35.5% and 36.4%, respectively). Transport and pedestrian injuries and hand and wrist injuries had high PPVs (96.5% and 92.0%, respectively). Specificity and NPV were generally high, except for abuse (NPV 44.6%).

CONCLUSIONS AND SIGNIFICANCE

The validity and reliability of ICD-10 external cause injury codes vary based on the injury types coded and the outcomes examined, and overall, they only perform moderately well. Future work, potentially utilizing artificial intelligence, may improve the validity and reliability of ICD codes used to document injuries.

In-hospital complications of work-related musculoskeletal injuries

BACKGROUND, OBJECTIVES

Work-related musculoskeletal (MSK) injuries are a major contributor to morbidity worldwide and frequently result in hospitalisation. Hospital complications are common, costly, and largely preventable, but relevant data is required to address this. This study aimed to identify the incidence and factors associated with in-hospital complications of work-related MSK injuries.

METHODS

This study is based on work-related MSK hospital admission data from Victorian Admitted Episodes Database, 2016-2022. Complications were identified based on ICD-10-AM coding using CHADx (Classification of Hospital Acquired Diagnoses). Negative binomial and logistic regression analyses were performed to identify factors related to in-hospital complications.

RESULTS

In-hospital complications occurred in 6.3 % of work-related MSK injury admissions. In the adjusted models, ages ≥45 years, female sex, and area-level disadvantage were associated with in-hospital complications. Stay at public (vs private) hospitals, comorbidity, emergency admissions, and general anaesthesia were also associated. Complication rates were higher in hospitalised workers with direct head, neck, and trunk injuries and cumulative MSK disorders than those with direct extremities injuries and acute MSK conditions. The most common complications were cardiovascular, gastrointestinal complications and adverse drug events.

CONCLUSION

This study identified patient, injury and hospital-related characteristics associated with in-hospital complications of work-related MSK injuries for informing prevention strategies and risk estimation by hospital staff and workers' compensation schemes. The results demonstrate a sizable rate of complications given the relatively young and healthy study population.

Clinical observation of gastrointestinal function recovery in patients after hepatobiliary surgery

BACKGROUND

The liver is an important metabolic and digestive organ in the human body, capable of producing bile, clotting factors, and vitamins.

AIM

To investigate the recovery of gastrointestinal function in patients after hepatobiliary surgery and identify effective rehabilitation measures.

METHODS

A total of 200 patients who underwent hepatobiliary surgery in our hospital in 2022 were selected as the study subjects. They were divided into a control group and a study group based on the extent of the surgery, with 100 patients in each group. The control group received routine treatment, while the study group received targeted interventions, including early enteral nutrition support, drinking water before gas discharge, and large bowel enema, to promote postoperative gastrointestinal function recovery. The recovery of gastrointestinal function was compared between the two groups.

RESULTS

Compared with the control group, patients in the study group had better recovery of bowel sounds and less accumulation of fluids in the liver bed and gallbladder fossa (P < 0.05). They also had shorter time to gas discharge and first meal (P < 0.05), higher overall effective rate of gastrointestinal function recovery (P < 0.05), and lower incidence of postoperative complications (P < 0.05).

CONCLUSION

Targeted nursing interventions (early nutritional support, drinking water before gas discharge, and enema) can effectively promote gastrointestinal function recovery in patients undergoing hepatobiliary surgery and reduce the incidence of complications, which is worthy of promotion.

An intricate vagina penetrating injury with a 22 cm cassava stick in situ for 6 months: a case report

BACKGROUND

Trauma remains one of the major causes of morbidity and mortality and a threat to attainment of sustainable development goal 11. Genital urinary trauma is reported in about 10% of patients presenting with trauma worldwide, and in about 6.6% of patients in Sub-Saharan Africa. If not careful enough, one may miss the foreign body in the vagina and this may be associated with morbidity, and although  rare, mortality.

CASE PRESENTATION

We report a case of a 7-year-old Black Ugandan that had suffered vagina trauma 6 months prior to presentation at our facility and presented with chronic vagina pus discharge for 6 months. Prior examinations had failed to recognize the foreign body and so did the two abdominal pelvic ultrasound scans. During examination under anesthesia, we were able to locate the cassava stick that had caused penetrating vagina injury and we were able to dislodge it. It was a blunt cassava stick with length of 22 cm and diameter of 2 cm. Although it had gone through the peritoneal cavity, we did not do a laparotomy.

CONCLUSION

This case emphasizes the need for a thorough vaginal exam including the need to do it under anesthesia with good lighting even when ultrasound scan findings are normal. It presents an opportunity for one to manage penetrating peritoneal injury without a laparotomy in highly selected cases. Gynecologists should be keen as well to rule out child molestation.

Review of the India Adolescent Health Strategy in the context of disease burden among adolescents

Background

A nuanced understanding of the health needs of adolescents in the context of the India Adolescent Health Strategy (IAHS) is needed to inform policy interventions for improving the health and well-being of adolescents in India.

Methods

Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, we identified the top ten causes of years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) disaggregated by sex and age group (10-14 and 15-19 years) for India and its states in 2019. To inform the IAHS of refinement or expansion in focus needed to improve adolescent health in India, we reviewed the extent to which the top 10 causes of disease burden are addressed in the IAHS, and the availability of and age- and sex-disaggregation in the service utilisation data for adolescents captured in the Adolescent Friendly Health Clinic monitoring information system (AFHC MIS) and Health Management Information System (HMIS). We also reviewed the availability of and age-and sex-disaggregation in the data capture at the population level for the IAHS outcome indicators in the data sources identified in the IAHS operational framework.

Findings

Females in the 10-14 and 15-19 years age groups suffered 6.75 million and 9.25 million DALYs, respectively, 39.1% and 44.2% of which were YLLs; the corresponding DALYs for males were 6.71 million and 9.65 million (42.3% and 41.1% YLLs), respectively. Within the 6 thematic areas of the IAHS, most strategies and indicators identified are for sexual and reproductive health followed by nutrition, and broadly these conditions accounted for YLDs and not YLLs in adolescents. Significant gaps in the IAHS in comparison to the disease burden for fatal diseases and conditions were seen across injuries, communicable diseases, and non-communicable diseases. Injuries accounted for 65.9% and 45.3% of YLLs in males and females aged 15-19 years, and 40.8% in males aged 10-14 years. Specifically, road injuries (15.3%, 95% UI 11.0-18.0) and self-harm (11.3%, 95% UI 8.7-14.2) accounted for most of the injury deaths in 15-19 years whereas drowning (7.7% 95% UI 5.8-9.6) and road injuries (6.9%, 95% UI 4.7-8.6) accounted for the most injury deaths in 10-14 years males. However, only self-harm and gender-based violence are specifically addressed in the IAHS with non-specific interventions for other injuries. Diarrhoea, lower respiratory infections, malaria, encephalitis, tuberculosis, typhoid, cirrhosis, and hepatitis are the other disease conditions accounting for YLLs and DALYs in adolescents but these are neither addressed in the IAHS nor in service provision under the AFHC MIS. There is no age- or sex-disaggregation in the cause of death data captured in the HMIS to allow an understanding of mortality in adolescents. For the IAHS outcome indicators at the population level, data capture for the 10-14 years irrespective of sex was largely missing from the population surveys and none of the surveys captured data for either females or males aged 15-19 years for physical inactivity and mental health indicators.

Interpretation

The considerable differences seen in the IAHS thematic focus as compared with the leading causes of fatal and non-fatal disease burden in adolescents in India, and in the availability of population-level data to monitor the outcome indicators of the IAHS can pose substantial limitations for improving adolescent health in India. The findings in this paper can be utilized by decision makers to refine action aimed at improving adolescent health and well-being.

Trends in mortality from non-natural causes in children and adolescents (0-19 years) in Europe from 2000 to 2018

BACKGROUND

Non-natural mortality in children and adolescents is a global public health problem that varies widely from country to country. Data on child and adolescent maltreatment are not readily available, and mortality due to violent causes is also underestimated.

METHODS

Injury-related mortality rates (overall and by specific causes) from 2000 to 2018 in selected European countries were analysed to observe mortality patterns in children and adolescents using data from the Eurostat database. Age-standardized mortality rates per 100,000 person-years were calculated for each country. Joinpoint regression analysis with a significance level of 0.05 and 95% confidence intervals was performed for mortality trends.

RESULTS

Children and adolescent mortality from non-natural causes decreased significantly in Europe from 10.48 around 2005 to 5.91 around 2015. The Eastern countries (Romania, Bulgaria, Poland, Slovakia, Czech Republic) had higher rates; while Spain, Denmark, Italy, and the United Kingdom had the lowest. Rates for European Country declined by 5.10% per year over the entire period. Larger downward trends were observed in Ireland, Spain and Portugal; smaller downward trends were observed for Eastern countries (Bulgaria, Czech Republic, Poland, Slovakia) and Finland. Among specific causes of death, the largest decreases were observed for accidental causes (-5.9%) and traffic accidents (-6.8%).

CONCLUSIONS

Mortality among children and adolescents due to non-natural causes has decreased significantly over the past two decades. Accidental events and transport accidents recorded the greatest decline in mortality rates, although there are still some European countries where the number of deaths among children and adolescents from non-natural causes is high. Social, cultural, and health-related reasons may explain the observed differences between countries.

Hypofibrinogenemia following injury in 186 children and adolescents: identification of the phenotype, current outcomes, and potential for intervention

Objectives

Recent studies evaluating fibrinogen replacement in trauma, along with newly available fibrinogen-based products, has led to an increase in debate on where products such as cryoprecipitate belong in our resuscitation strategies. We set out to define the phenotype and outcomes of those with hypofibrinogenemia and evaluate whether fibrinogen replacement should have a role in the initial administration of massive transfusion.

Methods

All patients <18 years of age presenting to our trauma center 11/17-4/21 were reviewed. We then evaluated all patients who received emergency-release and massive transfusion protocol (MTP) products. Patients were defined as hypofibrinogenemic (HYPOFIB) if admission fibrinogen <150 or rapid thrombelastography (r-TEG) angle <60 degrees. Our analysis sought to define risk factors for presenting with HYPOFIB, the impact on outcomes, and whether early replacement improved mortality.

Results

4169 patients were entered into the trauma registry, with 926 level 1 trauma activations, of which 186 patients received emergency-release blood products during this time; 1%, 3%, and 10% were HYPOFIB, respectively. Of the 186 patients of interest, 18 were HYPOFIB and 168 were non-HYPOFIB. The HYPOFIB patients were significantly younger, had lower field and arrival Glasgow Coma Scale, had higher head Abbreviated Injury Scale, arrived with worse global coagulopathy, and died from brain injury. Non-HYPOFIB patients were more likely to have (+)focused assessment for the sonography of trauma on arrival, sustained severe abdominal injuries, and die from hemorrhage. 12% of patients who received early cryoprecipitate (0-2 hours) had higher mortality by univariate analysis (55% vs 31%, p=0.045), but no difference on multivariate analysis (OR 0.36, 95% CI 0.07 to 1.81, p=0.221). Those receiving early cryoprecipitate who survived after pediatric intensive care unit (PICU) admission had lower PICU fibrinogen and r-TEG alpha-angle values.

Conclusion

In pediatric trauma, patients with hypofibrinogenemia on admission are most likely younger and to have sustained severe brain injury, with an associated mortality of over 80%. Given the absence of bleeding-related deaths in HYPOFIB patients, this study does not provide evidence for the empiric use of cryoprecipitate in the initial administration of a massive transfusion protocol.

The Diagnostic, Therapeutic and Prognostic Relevance of Neutrophil Extracellular Traps in Polytrauma

Neutrophil extracellular traps (NETs) represent a recently discovered polymorphonuclear leukocyte-associated ancient defence mechanism, and they have also been identified as part of polytrauma patients' sterile inflammatory response. This systematic review aimed to determine the clinical significance of NETs in polytrauma, focusing on potential prognostic, diagnostic and therapeutic relevance. The methodology covered all major databases and all study types, but was restricted to polytraumatised humans. Fourteen studies met the inclusion criteria, reporting on 1967 patients. Ten samples were taken from plasma and four from whole blood. There was no standardisation of methodology of NET detection among plasma studies; however, of all the papers that included a healthy control NET, proxies were increased. Polytrauma patients were consistently reported to have higher concentrations of NET markers in peripheral blood than those in healthy controls, but their diagnostic, therapeutic and prognostic utility is equivocal due to the diverse study population and methodology. After 20 years since the discovery of NETs, their natural history and potential clinical utility in polytrauma is undetermined, requiring further standardisation and research.

Unmasking the Underlying Causes: A Cross-Sectional Analysis of Mortality From Intentional and Unintentional Injuries in the United Arab Emirates

The United Arab Emirates (UAE) has experienced substantial development in infrastructure and transportation in the last few decades. Although available evidence suggests that the incidence of injuries has considerably increased in the previous few years, there is a scarcity of literature that comprehensively analyzed the mortality due to different types of injuries in the UAE. Therefore, the current study was designed to report mortality due to various intentional and unintentional injuries in the UAE. Secondary data was obtained from the World Health Organization (WHO) mortality database. We targeted injuries-specific mortality datasets. We applied a filter (UAE) to retrieve mortality data from unintentional and intentional injuries in the UAE. The latest data in the WHO mortality database was for 2020-21. A total of 10,357 death records from the UAE were present in the WHO mortality database. The percentage of injury-specific deaths out of total deaths was 8.69% (n=900). Injury-specific mortality rate per 100,000 population was 9.09. The percentage of injury-specific deaths was higher for males (87.3%, n=786) and the age group 25-34 years (n=323, 35.9%). Of the 900 injury-specific deaths, 449 (49.9%) were due to unintentional injuries, 216 (24.0%) were due to unintentional injuries, while the remaining (26.1%, n=235) deaths occurred due to Ill-defined injuries. More than half (53.7%, n=241) of unintentional injuries were because of road traffic injuries (RTIs) followed by fall (14.7%, n=66), exposure to mechanical forces (6.5%, n=29), drowning (6.0%, n=27) fire (1.1%, n=5), poisonings (1.1%, n=5), natural disasters (n=1, 0.2%) and other unintentional injuries (16.7%, n=75). More than three-quarters (83.3%, n=180) of intentional injuries were because of self-inflicted injuries while the remaining (16.7%, n=36) intentional injuries-specific deaths occurred due to violence. Many deaths in the UAE occur due to unintentional and intentional injuries. RTIs and falls are the leading causes of unintentional injury-specific deaths, while self-inflicted injuries and violence are the leading causes of intentional injury-specific deaths.

Cause-specific accidental deaths and burdens related to ambient heat in a warming climate: A nationwide study of China

BACKGROUND

Future warming is projected to increase the heat-related mortality burden, especially for vulnerable populations. However, most previous studies focused on non-accidental morbidity or mortality, with far less research on heat-related accidental events.

METHODS

We collected individual accidental death records among all residents in Chinese mainland from June to August during 2013-2019. Accidental deaths were further divided into several subtypes by different causes. We used an individual-level, time-stratified, case-crossover study design to estimate the association between daily mean temperature and accidental deaths, and estimate its variation in seven geo-climatic zones, age (5-64, 65-74, ≥75), and sex (male, female). We then estimated the temperature-related excess accidental deaths under global warming scenarios of 1.5, 2, and 3℃.

FINDINGS

A total of 711,929 accidental death records were included in our study. We found that higher temperatures were associated with increased risks of deaths from the total accidental events and four main subtypes, including traffic, falls, drowning, and unintentional injuries. We also found that younger individuals (ages 5-64) and males faced a higher risk of heat-related mortality due to total accidents, traffic incidents, and drowning. For future climate scenarios, even under the 1.5℃ climate change scenario, 6,939 (95% eCI (empirical Confidence Interval): 6,818-7,067) excess accidental deaths per year are attributed to higher summertime daily temperature over mainland China, and the number of accidental deaths would increase by 16.71% and 33.59% under the 2℃ and 3℃ climate change scenarios, respectively. For residents living in southern coastal and northwest inland regions, the projected increase in accidental death is higher.

CONCLUSIONS

This nationwide study confirms that higher summer temperatures are linked to an increased risk of accidental deaths. Younger age groups and males face a higher risk. This indicates that current estimates of the health effects of climate change might be underestimated, particularly for younger populations.

Development of the Indian Reference Case for undertaking economic evaluation for health technology assessment

Background

Health technology assessment (HTA) is globally recognised as an important tool to guide evidence-based decision-making. However, heterogeneity in methods limits the use of any such evidence. The current research was undertaken to develop a set of standards for conduct of economic evaluations for HTA in India, referred to as the Indian Reference Case.

Methods

Development of the reference case comprised of a four-step process: (i) review of existing international HTA guidelines; (ii) systematic review of economic evaluations for three countries to assess adherence with pre-existing country-specific HTA guidelines; (iii) empirical analysis to assess the impact of alternate assumptions for key principles of economic evaluation on the results of cost-effectiveness analysis; (iv) stakeholder consultations to assess appropriateness of the recommendations. Based on the inferences drawn from the first three processes, a preliminary draft of the reference case was developed, which was finalised based on stakeholder consultations.

Findings

The Indian Reference Case provides twelve recommendations on eleven key principles of economic evaluation: decision problem, comparator, perspective, source of effectiveness evidence, measure of costs, health outcomes, time-horizon, discounting, heterogeneity, uncertainty analysis and equity analysis, and for presentation of results. The recommendations are user-friendly and have scope to allow for context-specific flexibility.

Interpretation

The Indian Reference Case is expected to provide guidance in planning, conducting, and reporting of economic evaluations. It is anticipated that adherence to the Reference Case would increase the quality and policy utilisation of future evaluations. However, with advancement in the field of health economics efforts aimed at refining the Indian Reference Case would be needed.

Pediatric Traumatic Brain Injury in Malawi: A Propensity-Weighted Analysis of Outcomes and Trends Over Time

BACKGROUND

Pediatric injuries contribute to substantial mortality and morbidity worldwide, particularly in sub-Saharan Africa. We aim to identify predictors of mortality and time trends for pediatric traumatic brain injuries (TBIs) in Malawi.

METHODS

We performed a propensity-matched analysis of data from the trauma registry at Kamuzu Central Hospital in Malawi from 2008 to 2021. All children ≤16 years of age were included. Demographic and clinical data were collected. Outcomes were compared between patients with and without head injuries.

RESULTS

A cohort of 54,878 patients was included, with 1755 having TBI. The mean ages of patients with and without TBI were 7.8 ± 7.8 years and 7.1 ± 4.5 years, respectively. The most common mechanism for patients with and without TBI was road traffic injury and falls, respectively (48.2% vs. 47.8%, P < 0.01). The crude mortality rate for the TBI cohort was 20.9% compared to 2.0% in the non-TBI cohort (P < 0.01). After propensity matching, patients with TBI had 4.7 higher odds of mortality (95% confidence interval 1.9-11.8). Over time, patients with TBI had an increasing predicted probability of mortality for all age categories, with the most significant increase among children younger than 1 year.

CONCLUSIONS

TBI confers a greater than 4-fold higher likelihood of mortality in this pediatric trauma population in a low-resource setting. These trends have worsened over time.

The Current State of Undergraduate Trauma and Orthopedics Training in Saudi Arabia: A Survey-Based Study of Sixth-Year Medical Students' and Interns' Learning Experience and Subjective Clinical Competence

Background and objective Students frequently complain about the lack of practical skill learning and the poor quality of the medical school curriculum. In light of this, the purpose of this study was to assess the learning experience and subjective clinical competence of final-year medical students and interns in the field of orthopedics in Saudi Arabia (SA). Methods A cross-sectional observational descriptive study utilizing an electronically validated survey was conducted, which included the following six main sections: introduction, demographics, self-assessment of competency regarding certain orthopedic skills, clinical experience in orthopedics, orthopedics curriculum assessment, and choice of future career specialty. Results The total number of participants was 794. Among them, 33% (n=160) and 37.1% (180) had attended no "trauma meetings" or "operating room (OR)" sessions respectively, and only 21.9% (n=106) had attended more than five clinics. Subjective competence in history taking was highest (mean: 8.925 ±1.299) among students who had received more than four weeks of orthopedic rotation and attended more than six clinics. The students who had completed more than four weeks of orthopedic rotation and more than six bedside sessions scored the highest in terms of subjective competence in handling orthopedic patients in primary care settings (mean: 8.014 ±1.931). Conclusion The survey indicates that the amount of orthopedic training provided by institutions varies, with some students receiving less training than recommended. However, longer rotations lead to greater perceived orthopedic competence. Students and interns with more exposure to orthopedics through curriculum and elective rotations demonstrated a greater interest in pursuing orthopedics as a future career.

Neglected burden of injuries in Ethiopia, from 1990 to 2019: a systematic analysis of the global burden of diseases study 2019

Background

The 2030 agenda for sustainable development goals has given injury prevention new attention, including halving road traffic injuries. This study compiled the best available evidence on injury from the global burden of diseases study for Ethiopia from 1990 to 2019.

Methods

Injury data on incidence, prevalence, mortality, disability-adjusted life years lost, years lived with disability, and years of life lost were extracted from the 2019 global burden of diseases study for regions and chartered cities in Ethiopia from 1990 to 2019. Rates were estimated per 100,000 population.

Results

In 2019, the age-standardized rate of incidence was 7,118 (95% UI: 6,621-7,678), prevalence was 21,735 (95% UI: 19,251-26,302), death was 72 (95% UI: 61-83), disability-adjusted life years lost was 3,265 (95% UI: 2,826-3,783), years of live lost was 2,417 (95% UI: 2,043-2,860), and years lived with disability was 848 [95% UI: (620-1,153)]. Since 1990, there has been a reduction in the age-standardized rate of incidence by 76% (95% UI: 74-78), death by 70% (95% UI: 65-75), and prevalence by 13% (95% UI: 3-18), with noticeable inter-regional variations. Transport injuries, conflict and terrorism, interpersonal violence, self-harm, falls, poisoning, and exposure to mechanical forces were the leading causes of injury-related deaths and long-term disabilities. Since 1990, there has been a decline in the prevalence of transport injuries by 32% (95% UI: 31-33), exposure to mechanical forces by 12% (95% UI: 10-14), and interpersonal violence by 7.4% (95% UI: 5-10). However, there was an increment in falls by 8.4% (95% UI: 7-11) and conflict and terrorism by 1.5% (95% UI: 38-27).

Conclusion

Even though the burden of injuries has steadily decreased at national and sub-national levels in Ethiopia over the past 30 years, it still remains to be an area of public health priority. Therefore, injury prevention and control strategies should consider regional disparities in the burden of injuries, promoting transportation safety, developing democratic culture and negotiation skills to solve disputes, using early security-interventions when conflict arises, ensuring workplace safety and improving psychological wellbeing of citizens.

Core health indicators in countries with high proportion of expatriates: Case study of Qatar

Background

Population size and structure have a huge impact on health indicators. In countries with a high proportion of expatriates, there are some limitations in estimating, aggregating and reporting of the health indicators, and corrections may be required in the established estimation methodologies. We review the case of Qatar to see how its specific population characteristics affect its health indicators.

Methods

We used routinely collected data and reviewed and calculated a selected list of health indicators for Qatari and non-Qatari populations residing in Qatar. Mortality and cancer incidence rates, stratified by nationality, were used for this purpose. Also, a direct method was used to estimate completeness of the death registry, compared to the mortuary data.

Results

Age and sex distribution of Qatari and non-Qatari populations are completely different. Compared to the mortuary data, completeness of death registration for the total population was estimated at 98.9 and 94.3%, with and without considering overseas deaths, respectively. Both estimates were considerably higher than estimates from the indirect methods. Mortality patterns were different even after standardization of age and stratification of sex groups; male age-standardized mortality rates were 502.7 and 242.3 per 100,000 individuals, respectively for Qataris and non-Qataris. The rates were closer in female populations (315.6 and 291.5, respectively). The leading types of cancer incidents were different in Qataris and non-Qataris.

Conclusions

Expatriates are a dynamic population with high-turnover, different from Qatari population in their age-sex structure and health status. They are more likely to be young or middle-aged and are less affected by age related diseases and cancers. Also, they might be at higher risks for specific diseases or injuries. Aggregating indicators of Qatari and non-Qatari populations might be mis-leading for policy making purposes, and common estimation correction approaches cannot alleviate the limitations. High-proportion of expatriate population also imposes significant errors to some of the key demographic estimates (such as completeness of death registry). We recommend a standardized approach to consider nationality in addition to age and sex distributions for analysis of health data in countries with a high proportion of expatriates.

Access to medical care and its association with physical injury in adolescents: a cross-national analysis

BACKGROUND

Strong variations in injury rates have been documented cross-nationally. Historically, these have been attributed to contextual determinants, both social and physical. We explored an alternative, yet understudied, explanation for variations in adolescent injury reporting-that varying access to medical care is, in part, responsible for cross-national differences.

METHODS

Age-specific and gender-specific rates of medically treated injury (any, serious, by type) were estimated by country using the 2013/2014 Health Behaviour in School-aged Children study (n=209 223). Available indicators of access to medical care included: (1) the Healthcare Access and Quality Index (HAQ; 39 countries); (2) the Universal Health Service Coverage Index (UHC; 37 countries) and (3) hospitals per 100 000 (30 countries) then physicians per 100 000 (36 countries). Ecological analyses were used to relate injury rates and indicators of access to medical care, and the proportion of between-country variation in reported injuries attributable to each indicator.

RESULTS

Adolescent injury risks were substantial and varied by country and sociodemographically. There was little correlation observed between national level injury rates and the HAQ and UHC indices, but modest associations between serious injury and physicians and hospitals per 100 000. Individual indicators explained up to 9.1% of the total intercountry variation in medically treated injuries and 24.6% of the variation in serious injuries.

CONCLUSIONS

Cross-national variations in reported adolescent serious injury may, in part, be attributable to national differences in access to healthcare services. Interpretation of cross-national patterns of injury and their potential aetiology should therefore consider access to medical care as a plausible explanation.

Understanding the confluence of injury and obesity in a Grade 2 obesity and above population

OBJECTIVE

Obesity and injury are major inter-related public health challenges. The objective of this study was to explore the perceptions of injury in people with severe obesity.

METHODS

A cross-sectional design was employed to capture injury perception and lifestyle habits via questionnaires. Weight (kg) and height (m) were measured by clinicians for patients attending a weight loss group program. Univariate, chi-square, ANOVA and ordinal regression analyses were undertaken.

RESULTS

There were 292 participants (67.1% female), mean age 49.3 years and Body Mass Index 47.2 kg/m² (range 30.7-91.9 kg/m²). Concern about having an injury was found in 83%, and 74.2% thought that weight would increase the likelihood of injury. A greater concern of being injured at baseline was associated with less weight loss at eight weeks (F=3.567; p=0.03). Depression, anxiety and sleepiness score were higher in those who reported greater 'Concern about having an injury'.

CONCLUSIONS

People with obesity fear injury and falling, which limits their willingness to exercise. Anxiety symptoms appear to exacerbate this connection.

IMPLICATIONS FOR PUBLIC HEALTH

In individuals with obesity, anxiety, sleepiness and depression are associated with a fear of being injured. Addressing fear and reducing anxiety may decrease barriers to participating in physical activity.

Injuries among Canadian children and youth: an analysis using the 2019 Canadian Health Survey on Children and Youth

This work provides an overview of injury patterns in Canadian children and youth aged 1 to 17 years. Self-reported data from the 2019 Canadian Health Survey on Children and Youth were used to calculate estimates for the percentage of Canadian children and youth who experienced a head injury or concussion, broken bone or fracture, or serious cut or puncture within the last 12 months, overall and by sex and age group. Head injuries and concussions (4.0%) were the most commonly reported, but the least likely to be seen by a medical professional. Injuries most frequently occurred while engaging in sports, physical activity or playing.

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.
