Background: The COVID-19 pandemic has brought unprecedented changes globally, significantly affecting public health sectors, including paediatric road trauma. This study aims to explore the changes in paediatric road trauma presentations and outcomes before and after the COVID-19 lockdown., Methods: This retrospective study analysed paediatric trauma data from the Saudi TraumA Registry (STAR) from August 2017 to December 2022, comparing pre- and post-COVID-19 lockdown periods (August 2017-March 2020 and July 2020-December 2022, respectively). The study analysed demographic data, mechanism of injury, severity, ICU admissions, and mortality rates using multivariate logistic regression models., Results: Out of 950 paediatric trauma cases analysed, there was an 44.2 [561/389 = 1.442] % increase in the number of cases post-lockdown. A significant shift was noted in the age group of 5-9 years, with cases increasing from post-lockdown. Head injuries were the most prevalent type of injury, with their proportion slightly increasing from 163 (20.5%) pre-lockdown to 248 (23.2%) post-lockdown. The ICU admission were consistent across both periods, while the definitive care mode of arrival post-lockdown showed a notable shift towards private or government ambulances., Conclusion: Our study provides critical insights into the significant impact of the COVID-19 on paediatric road trauma. The observed increase in trauma cases post-pandemic, particularly among younger children and a notable rise in driver-related injuries among adolescents, underscores the profound effect of lockdown measures and subsequent societal changes on paediatric health. Efforts to reduce paediatric traffic injuries require collaboration among parents, educators, healthcare professionals, policymakers, and the community at large., (© 2024. The Author(s).)

Background: Pedestrian traffic injuries are a rising public health concern worldwide. In rapidly urbanizing countries like Saudi Arabia, these injuries account for a considerable proportion of trauma cases and represent a challenge for healthcare systems. The study aims to analyze the key characteristics, seasonality, and outcomes of pedestrian traffic injuries in Riyadh, Saudi Arabia., Methods: This study was a retrospective cohort analysis of all pedestrian traffic injuries presented to King Saud Medical City, Riyadh, and included in the Saudi Trauma Registry (STAR) database between August 1, 2017, and December 31, 2022. The analysis of metric and nominal variables was reported as mean (standard deviation, SD) or median (interquartile range, IQR) and frequencies (%), respectively. A logistic regression analysis was performed to examine the influence of patients' pre-hospital vitals and key characteristics on arrival at the ED on the need for mechanical ventilation and in-hospital mortality., Results: During the study period, 1062 pedestrian-injured patients were included in the analysis, mostly males (89.45%) with a mean (SD) age of 33.44 (17.92) years. One-third (35.88%) of the patients were Saudi nationals. Two-thirds (67.04%) of the injuries occurred from 6 p.m. until 6 a.m. Compared to other years, a smaller % of injury events (13.28%) were noticed during the COVID-19 pandemic (2020). Half (50.19%) of the patients were transported to the emergency department by the Red Crescent ambulance, and 19.68% required intubation and mechanical ventilation. Most of the patients (87.85%) were discharged home after completion of treatment, and our cohort had a 4.89% overall mortality. The logistic regression analysis showed the influence of patients' pre-hospital vitals and key characteristics on arrival at the ED on the need for mechanical ventilation (Chi 2  = 161.95, p < 0.001) and in-hospital mortality (Chi 2  = 63.78, p < 0.001) as a whole significant., Conclusion: This study details the demographic, temporal, and clinical trends of pedestrian traffic injuries at a major Saudi trauma center. Identifying high-risk individuals and injury timing is crucial for resource allocation, targeting road safety interventions like public awareness campaigns and regulatory reforms, and improving prehospital care and patient outcomes., (© 2024.

Introduction: Lockdown restrictions due to the COVID-19 pandemic have reduced the number of injuries recorded. However, little is known about the impact of easing COVID-19 lockdown restrictions on the nature and outcome of injuries. This study aims to compare injury patterns prior to and after the easing of COVID-19 lockdown restrictions in Saudi Arabia., Method: Data were collected retrospectively from the Saudi TraumA Registry for the period between March 25, 2019, and June 21, 2021. These data corresponded to three periods: March 2019-February 2020 (pre-restrictions, period 1), March 2020-June 2020 (lockdown, period 2), and July 2020-June 2021 (post easing of restrictions, period 3). Data related to patients' demographics, mechanism and severity of injury, and in-hospital mortality were collected and analysed., Results: A total of 5,147 traumatic injury patients were included in the analysis (pre-restrictions n = 2593; lockdown n = 218; post easing of lockdown restrictions n = 2336). An increase in trauma cases (by 7.6%) was seen in the 30-44 age group after easing restrictions (n = 648 vs. 762, p < 0.01). Motor vehicle crashes (MVC) were the leading cause of injury, followed by falls in all the three periods. MVC-related injuries decreased by 3.1% (n = 1068 vs. 890, p = 0.03) and pedestrian-related injuries decreased by 2.7% (n = 227 vs. 143, p < 0.01); however, burn injuries increased by 2.2% (n = 134 vs. 174, p < 0.01) and violence-related injuries increased by 0.9% (n = 45 vs. 60, p = 0.05) post easing of lockdown restrictions. We observed an increase in in-hospital mortality during the period of 12 months after easing of lockdown restrictions-4.9% (114/2336) compared to 12 months of pre-lockdown period-4.3% (113/2593)., Conclusion: This is one of the first studies to document trauma trends over a one-year period after easing lockdown restrictions. MVC continues to be the leading cause of injuries despite a slight decrease; overall injury cases rebounded towards pre-lockdown levels in Saudi Arabia. Injury prevention needs robust legislation with respect to road safety measures and law enforcement that can decrease the burden of traumatic injuries., (© 2023. The Author(s).)

Background: Traumatic injury remains the leading cause of death, with more than five million deaths every year. Little is known about the comparative effectiveness in reducing mortality of trauma care systems at different stages of development. The objective of this study was to review the literature and examine differences in mortality associated with different stages of trauma system development., Method: A systematic review of peer-reviewed population-based studies retrieved from MEDLINE, EMBASE, and CINAHL. Additional studies were identified from references of articles, through database searching, and author lists. Articles written in English and published between 2000 and 2020 were included. Selection of studies, data extraction, and quality assessment of the included studies were performed by two independent reviewers. The results were reported as odds ratio (OR) with 95 % confidence intervals (CI)., Results: A total of 52 studies with a combined 1,106,431 traumatic injury patients were included for quantitative analysis. The overall mortality rate was 6.77% (n = 74,930). When patients were treated in a non-trauma centre compared to a trauma centre, the pooled statistical odds of mortality were reduced (OR 0.74 [95% CI 0.69-0.79]; p < 0.001). When patients were treated in a non-trauma system compared to a trauma system the odds of mortality rates increased (OR 1.17 [95% CI 1.10-1.24]; p < 0.001). When patients were treated in a post-implementation/initial system compared to a mature system, odds of mortality were significantly higher (OR 1.46 [95% CI 1.37-1.55]; p < 0.001)., Conclusion: The present study highlights that the survival of traumatic injured patients varies according to the stage of trauma system development in which the patient was treated. The analysis indicates a significant reduction in mortality following the introduction of the trauma system which is further enhanced as the system matures. These results provide evidence to support efforts to, firstly, implement trauma systems in countries currently without and, secondly, to enhance existing systems by investing in system development., Systematic Review Registration Number: PROSPERO CRD42019142842 ., (© 2021.

Introduction: The introduction of trauma systems that began in the 1970s resulted in improved trauma care and a decreased rate of morbidity and mortality of trauma patients. Worldwide, little is known about the effectiveness of trauma care system at different stages of development, from establishing a trauma centre, to implementing a trauma system and as trauma systems mature. The objective of this study is to extract and analyse data from research that evaluates mortality rates according to different stages of trauma system development globally., Methods and Analysis: The proposed review will comply with the checklist of the 'Preferred reporting items for systematic review and meta-analysis'. In this review, only peer-reviewed articles written in English, human-related studies and published between January 2000 and December 2020 will be included. Articles will be retrieved from MEDLINE, EMBASE and CINAHL. Additional articles will be identified from other sources such as references of included articles and author lists. Two independent authors will assess the eligibility of studies as well as critically appraise and assess the methodological quality of all included studies using the Cochrane Risk of Bias for Non-randomised Studies of Interventions tool. Two independent authors will extract the data to minimise errors and bias during the process of data extraction using an extraction tool developed by the authors. For analysis calculation, effect sizes will be expressed as risk ratios or ORs for dichotomous data or weighted (or standardised) mean differences and 95% CIs for continuous data in this systematic review., Ethics and Dissemination: This systematic review will use secondary data only, therefore, research ethics approval is not required. The results from this study will be submitted to a peer-review journal for publication and we will present our findings at national and international conferences., Prospero Registration Number: CRD42019142842., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

• SA is ranked 23rd on the list of countries with the highest death rates from MVCs globally. • Many of the characteristics of an effective TS were not present in the current evaluation of SA TS. • Efforts to strengthen the presence of all components of the TS are recommended. • Each region in SA should have its own infrastructure that aligns with the national TS but fits with the region's resources. Trauma is one of the leading causes of death worldwide with millions of people dying each year, particularly in low or middle-income countries. This paper describes and evaluates the current trauma system (TS) in Saudi Arabia (SA). A scoping literature review was performed, incorporating an extensive search of Medline and Embase databases for refereed literature, as well as a search of grey literature to locate unpublished articles or reports in English or Arabic. All publications were assessed against the World Health Organization (WHO) Trauma System Maturity Index (TSMI) and American College of Surgeon's (ACS) criteria. Despite local injury prevention efforts, Motor Vehicle Crashes (MVC) remain the primary cause of injuries in SA. Prehospital trauma care in SA aligns with level III care as described in the WHO TSMI classification system, based on the presence of formal emergency medical services and universal access to care. With respect to the ACS classification, no clear written guidelines, either for field triage or trauma destination protocols such as trauma bypass, were identified in prehospital trauma care. The role of secondary and tertiary facilities in treating trauma patients is unclear, with no clear referral linkages, suggesting a level I to III grading of SA's trauma care facilities. Currently, there is no national or regional electronic trauma registry, no quality assurance program, and active involvement in research projects related to injuries is limited. The current SA TS has strengths but there are key features missing in comparison to other systems globally. As MVCs remain a leading cause of death/ disability, efforts to reduce the prevalence and impact of MVC burden in SA through development of a stronger national TS are warranted. [ABSTRACT FROM AUTHOR]
