[PMID: 33619002 DOI: 10.1016/j.auec.2021.01.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 01/31/2021] [Accepted: 01/31/2021] [Indexed: 11/15/2022]
Abstract
BACKGROUND Traffic related injuries are a major public health problem worldwide with millions of people dying every year. The objective of this state-of-the-art review was to identify the factors reported in the literature as being associated with mortality for trauma patients following road traffic crashes. METHOD A systematic search was undertaken of PubMed/MEDLINE, EMBASE, CINAHL, Web of Science, and Cochrane Library databases to identify articles published in the past two decades (2000-2020). Of 8257 records, 4507 remained for title, abstract and full text screening after duplicates were removed. The level of evidence of selected studies was assessed using The National Health and Medical Research Council (NHMRC) guideline. RESULTS This review included eighty primary research studies examining mortality risk factors following a road traffic crash. The study identified factors in five categories; (i) demographic factors; (ii) behavioural factors; (iii) crash characteristics; (iv) environmental and timing factors; (v) injury severity and pre-injury/condition. The primary studies are summarised in a matrix. Included studies included level II to level IV levels of evidence based on the NHMRC criteria. CONCLUSION This study shows that there are a large number of factors associated with increased risk of mortality following diverse types of traffic crashes. Understanding these wide-ranging factors can strengthen injury and mortality prevention by guiding decision makers about where to focus strategy implementation.

Abstract
Background The aim of this study was to describe the pattern of traumatic injuries and determine the predictors of inhospital mortality in patients admitted to the emergency department. Patients and methods This is a retrospective cohort study of 3,786 patients with traumat injuries admitted to the emergency department of King Abdulaziz Medical City, Riyadh, Saudi Arabia, between January 2012 and December 2014. Data on patient characteristics, trauma characteristics and outcomes were extracted from medical records. A negative binomial regression model was utilized to identify significant predictors of inhospital mortality. Results Of all injured patients, 77.5% were male, 29.8% were aged 15-25 years and 25.7% were aged 26-45 years. Blunt trauma was the main mechanism of injury, including motor vehicle crashes (MVCs) in 52.0% and falls in 25.8% of patients. Most patients had injuries to the extremities (61.3%), followed by the head (32.2%), chest (16.9%) and abdomen (8.9%). Injuries were mild in 49.7% of patients, moderate in 30.2% and severe in 20.1%. The sex of the patients was significantly associated with the mechanism of injury (p<0.001), severity (p<0.001), anatomical site of injury (p<0.001), admission to the intensive care unit (p<0.001), need for trauma team activation (p<0.001) and type of transportation to hospital (p<0.001). The predictors of inhospital mortality were age (rate ratio [RR] for each 10-year increase=1.174; p<0.001), falls and burns (RR=2.337 and 1.728; p<0.001) and moderate and severe injuries (RR=6.438 and 181.780; p<0.001). Conclusion Our results suggest different patterns of trauma injuries according to patient age and sex. MVCs were the leading cause of injuries, but falls and burns had the highest inhospital mortality. This suggests the need for a comprehensive national education and prevention programs that address all causes of injuries.

[PMID: 29185794 DOI: 10.1080/15389588.2017.1410545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/15/2017] [Accepted: 11/23/2017] [Indexed: 06/07/2023]
Abstract
OBJECTIVE Traffic crashes have high mortality and morbidity for young children. Though many specialized child restraint systems improve injury outcomes, no large-scale studies have investigated the cross-chest clip's role during a crash, despite concerns in some jurisdictions about the potential for neck contact injuries from the clips. This study aimed to investigate the relationship between cross-chest clip use and injury outcomes in children between 0 and 4 years of age. METHODS Child passengers between 0 and 4 years of age were selected from the NASS-CDS data sets (2003-2014). Multiple regression analysis was used to model injury outcomes while controlling for age, crash severity, crash direction, and restraint type. The primary outcomes were overall Abbreviated Injury Score (AIS) 2+ injury, and the presence of any neck injury. RESULTS Across all children aged 0-4 years, correct chest clip use was associated with decreased Abbreviated Injury Scale (AIS) 2+ injury (odds ratio [OR] = 0.44, 95% confidence interval [CI], 0.21-0.91) and was not associated with neck injury. However, outcomes varied by age. In children <12 months old, chest clip use was associated with decreased AIS 2+ injury (OR = 0.09, 95% CI, 0.02-0.44). Neck injury (n = 7, all AIS 1) for this age group only occurred with correct cross-chest clip use. For 1- to 4-year-old children, cross-chest clip use had no association with AIS 2+ injury, and correct use significantly decreased the odds of neck injury (OR = 0.49; 95% CI, 0.27-0.87) compared to an incorrectly used or absent cross-chest clip. No serious injuries were directly caused by the chest clips. CONCLUSIONS Correct cross-chest clip use appeared to reduce injury in crashes, and there was no evidence of serious clip-induced injury in children in 5-point harness restraints.

Abstract
Rollover crashes (ROCs) are responsible for almost a third of all highway vehicle occupant fatalities. Although ROCs are common and serious mechanism of injury, ROCs are under-reported. To analyze the causes, mechanism, impact and prevention of ROCs, we reviewed the literature between 1984 and 2013. By utilizing the search engines PubMed, MEDLINE and EMBASE by using key words “ROCs” “Ejection” and “vehicle” the initial search yielded 241 abstracts, of which 58 articles were relevant. Most of the articles were either retrospective or experimental studies funded by automobile companies. All vehicles are susceptible to rollovers to certain extents. Despite continuing innovation in vehicles’ safety, human factor is pivotal in prevention of ROCs. Distracted driving, speeding and drinking escalate the chances of rollover crashes. Wearing a seatbelt greatly improves the chances of surviving a ROC.

Abstract
OBJECTIVE There is limited knowledge of the long-term medical consequences for children injured in car crashes. Thus, in the event of injury, the aim of the study was to specify patterns and risks of injuries resulting in permanent medical impairment of children (0-12 years) for different body regions and injury severity levels, according to Abbreviated Injury Scale (AIS). The aim was also to compare the impairment outcome with adults. METHODS Data were obtained from the Folksam insurance company, including reported car crashes from 1998 to 2010 with at least one injured child 0-12 years of age. In all, 2619 injured children with 3704 reported medical diagnoses were identified. All injuries were classified according to the AIS 2005 revision. If the child had not recovered within 1 year postinjury an assessment of permanent medical impairment (PMI) was made by one or several medical specialists. RESULTS In all, 55 children sustained 59 injuries resulting in PMI of which 75 percent were at AIS 1 or AIS 2. The head and cervical spine were the body regions sustaining the most injuries resulting in PMI. Sixty-eight percent of all injuries resulting in PMI were AIS 1 injuries to the cervical spine, with the majority occurring in frontal or rear impacts. Given an injury to the cervical spine, the risk of injuries resulting in PMI was 3 percent, and older children (≥6 years) had a significantly higher risk (3% versus 1%) than younger children. The head was the second most commonly injured body region with injuries resulting in PMI (12/59), which were predominantly AIS 2+. In addition, mild traumatic brain injuries at AIS 1 were found to lead to PMI. Whereas for children the injuries leading to PMI were primarily limited to the head and cervical spine, adults sustained injuries that led to PMI from a more diverse distribution of body regions. CONCLUSION The pattern of injuries resulting in permanent medical impairment is different for children and adults; therefore, safety priorities for children need to be based on child data. The majority of those injuries leading to PMI were at lower AIS levels. Furthermore, AIS 1 cervical spine and AIS 1+ head injuries should be given priority concerning mitigation of long-term consequences for children.

Abstract
OBJECTIVE Because of the lack of pediatric biomechanical data, Hybrid-III (HIII) child anthropomorphic test devices (ATDs) are essentially scaled from the mid-size male ATD based on the geometric considerations. These ATDs inherit a rigid thoracic spine from the adult HIII ATDs, which has been criticized as unrealistic. Therefore, the objective of this study was to explore possible design modifications for improving the spine biofidelity of the HIII 6-year-old ATD. METHODS A previously developed and validated HIII 6-year-old MADYMO ATD model was used as the baseline model to investigate the effects of design modifications on the spine biofidelity of the current ATD. Several sets of child volunteer and cadaver test data were considered as the design targets, including child volunteer low-speed crash test data, pediatric cadaver cervical spine tensile test data, and child cadaver crash test data. ATD design modifications include adding an additional joint to the thoracic spine region and changing the joint characteristics at the cervical and lumbar spine regions. Optimization techniques were used to match simulation results to each set of test results. RESULTS The results indicate that the translational characteristics of the cervical and lumbar spine in the current child ATD need to be reduced to achieve realistic spine flexibility. Adding an additional joint at the thoracic spine region with degree of freedom in both flexion/extension and tension would significantly improve the ATD biofidelity in terms of predicting the overall spine curvature and head excursion in frontal crashes. CONCLUSIONS Future ATD spine modification should focus on reducing the neck and lumbar tension stiffness and adding additional flexibility both in flexion/extension and tension at the thoracic spine region. The child ATD model developed in this study can be used as an important tool to improve child ATD biofidelity and child restraint system design in motor vehicle crashes.

Abstract
OBJETIVO: Avaliar o nível de conhecimento dos pais sobre segurança no transporte de crianças em veículos automotores e motocicletas. MÉTODOS: Estudo transversal, realizado por meio de questionário autoaplicável em pais e responsáveis que acompanhavam crianças na sala de espera de ambulatórios público e privado. Para avaliar os conhecimentos sobre segurança no transporte de crianças, foram utilizadas as recomendações da Associação Brasileira de Medicina do Tráfego. A análise dos dados foi realizada por meio do teste do qui-quadrado e as variáveis quantitativas testadas por Mann-Whitney, sendo significante p<0,05. RESULTADOS: A amostra foi composta por 248 pais, sendo 119 da rede privada e 129 da rede pública. Dentre as questões relacionadas com motocicletas, 76% daqueles que costumam transportar crianças nesse veículo acertaram a idade mínima permitida, todavia mais de 30% não acertaram a posição segura para tal. Quanto ao transporte em automóveis, a questão com maior percentual de respostas corretas foi referente à idade mínima para utilizar o banco da frente, com 64% de acertos. Nas demais questões, estes variaram de 24 a 46%. CONCLUSÕES: O conhecimento da população estudada sobre a segurança no transporte de crianças em veículos automotores é deficiente, tanto no emprego de dispositivos de retenção, pré-requisitos para o uso do banco da frente, bem como idade e forma de transporte de crianças em motocicletas.

Abstract
OBJECTIVES Head injuries are the most common serious injuries sustained by children in motor vehicle crashes and are of critical importance with regard to long-term disability. There is a lack of understanding of how seat belt-restrained children sustain head injuries in frontal impacts. The aim of the study was to identify the AIS2+ head injury causation scenarios for rear-seated, belt-restrained children in frontal impacts, including the set of parameters contributing to the injury. METHOD In-depth crash investigations from two National Highway Traffic Safety Administration (NHTSA) databases, the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS; 1997-2008) and the Crash Injury Research and Engineering Network (CIREN; 1996-2009), were collected and analyzed in detail. Selection criteria were all frontal impacts with principal direction of force (PDOF) of 11, 12, and 1 o'clock involving rear-seated, three-point belt-restrained, with or without booster cushion, children from 3 to 13 years with an AIS2+ head injury. Cases were analyzed using the BioTab method of injury causation assessment in order to systematically analyze the injury causation scenario for each case. RESULTS There were 27 cases meeting the inclusion criteria, 19 cases with MAIS2 head injuries and 8 cases with MAIS3+ head injuries, including 2 fatalities. Three major injury causation scenarios were identified, including head contact with seatback (10 cases), head contact with side interior (7 cases,) and no evidence of head contact (9 cases). CONCLUSIONS Head injuries with seatback or side interior contact typically included a PDOF greater than 10 degree (similar to the Insurance Institute for Highway Safety [IIHS] and EuroNCAP offset frontal testing) and vehicle maneuvers. For seatback contact, the vehicle's movements contributed to occupant kinematics inboard the vehicle, causing a less than optimal restraint of the torso and/or torso roll out of the shoulder belt. For side interior contact, the PDOF and/or maneuvers forced the occupant toward the side interior. The cases without evidence of head/face contact were characterized by high crash severity and accompanied by severe injuries to the thorax and spine. These data lead to increased understanding of the injury patterns and causation in this crash restraint scenario so that interventions to mitigate the burden of injury can be advanced.

Abstract
OBJECTIVE Head injury is the most common cause of death for child occupants in motor vehicle crashes (MVCs). The morbidity associated with nonlethal MVC-related head injuries is of great clinical consequence as well. The purpose of this study was to identify the frequency of, and risk factors for, clinically significant head injury (CSHI) in child occupants in MVCs. METHODS A large, child-specific crash surveillance system linking insurance claims data to telephone survey data was utilized. Qualifying crashes involved model year 1990 or newer vehicles in crashes with one or more child occupants (age 4 to 15 years) occurring in 15 U.S. states. Data were accrued between March 2000 and December 2007. A probability sample of crashes was selected for telephone survey with the driver of the insured vehicle. A clinically significant head injury, as reported by the child's parent using a validated survey, included concussions, skull fractures, and intracranial hemorrhages. Multivariate logistic regression was used to identify factors associated with a CSHI. RESULTS During the period of study, completed interviews were obtained on 19,075 children aged 4-15, representing 318,527 children involved in 219,511 crashes. The overall rate of CSHI in child occupants was 1.08 percent. Factors associated with an increased risk of head injury included rollover (odds ratio [OR] = 8.60, 95% confidence interval [CI] 6.40-11.57) and near-side impact crashes (OR = 2.39, 95% CI 1.73-3.30) vs. frontal impact; lack of restraint (OR = 3.13, 95% CI 2.26-4.33) vs. restrained; and driver age < 25 years (OR = 1.43, 95% CI 1.12-1.81) vs. driver age ≥ 25 years. Some factors varied based on occupant age, and younger child age had a protective effect on the risk for head injury. CONCLUSION The risk of CSHI for 4- to 15-year-old child occupants was 1.08 percent. Several demographic and crash factors were associated with CSHI in child occupants. This information may help inform design safety initiatives.

Abstract
Proteolytic processing plays an important role in regulating a wide range of important cellular functions, including processing of cytoskeletal proteins. Loss of cytoskeletal proteins such as spectrin is an important characteristic in a variety of acute central nervous system injuries including ischemia, spinal cord injury and traumatic brain injury (TBI). The literature contains extensive information on the proteolytic degradation of alpha-II-spectrin after TBI in the adult brain. By contrast, there is limited knowledge on the characteristics and relevance of these important processes in the immature brain. The present experiments examine TBI-induced proteolytic processing of alpha-II-spectrin after TBI in the immature rat brain. Distinct proteolytic products resulting from the degradation of the cytoskeletal protein alpha-II-spectrin by calpain and caspase 3 were readily detectable in cortical brain parenchyma and cerebrospinal fluid after TBI in immature rats.

Abstract
The history of numerous failed clinical trials designed to identify therapeutic agents to assist in improving outcomes after traumatic brain injury points to the critical importance of understanding biochemical markers of injury. Such biomarkers should be readily accessible, provide information specific to the pathologic disruptions occurring in the central nervous system, and allow improved monitoring of the progression of secondary damage. Additionally, these biomarkers should may provide investigators a window on the individual patient's response to treatment, and should contribute to prediction of outcome. Most research on this topic to date has focused on neuronspecific enolase (NSE) and S-100 proteins but these have not proven to be satisfactory for a variety of reasons. A different approach is provided by the study of 2 important proteases, caspase-3 and calpain. This paper reports the current state of knowledge concerning caspase and calpain as specific markers of TBI, and discusses all-spectrin, a principal substrate for both caspase and calpain, as well as initial findings regarding neurofilament 68 protein (NF-68).

Abstract
This study, describing the overall patterns of acute healthcare resource utilization by child crash victims (age 15 years and younger), was conducted between 28 July 1999 and 30 November 2000 as part of an on-going large-scale, child-specific crash surveillance system, Partners for Child Passenger Safety: insurance claims from 15 states and the District of Columbia function as the source of subjects, with telephone survey and on-site crash investigations serving as the primary sources of data. A probability sample of 4862 eligible crashes with 7368 child occupants formed the study sample. Our results suggest that for every 1000 children involved in crashes, 3 are hospitalized; 108 are treated and released from an emergency department (ED); 48 are evaluated in a physician's office, urgent care center, or other facility; and 841 receive no care at all. Comprehensive surveillance systems for motor vehicle crashes must capture children treated in physicians' offices, emergency departments, and other healthcare facilities in order to provide accurate estimates of the impact on the health care system related to motor vehicle trauma.

Abstract
Thoracic trauma remains a major source of morbidity and mortality in injured children, and is second only to brain injuries as a cause of death. The presence of a chest injury increases an injured child's mortality by 20-fold. Greater than 80% of chest injuries in children are secondary to blunt trauma. The compliant chest wall in children makes pulmonary contusions and rib fractures the most common chest injuries in children. Injuries to the great vessels, esophagus, and diaphragm are rare. Failure to promptly diagnose and treat these injuries results in increased morbidity and mortality.

Abstract
PURPOSE The purpose of this study was to report the incidence of ejection from the vehicle among children involved in motor vehicle crashes, and to describe a novel mode of ejection from child safety seats. METHODS The U.S. National Automotive Sampling System General Estimates System and the Fatality Analysis Reporting System databases from 1995 through 1999 were analyzed. A prospective two-center study of children involved in severe car crashes in Canada was performed. RESULTS Only 0.2% of 5.5 million children involved in crashes experienced ejection, but 1924 (29%) of 6570 child fatalities involved ejections. Only 2.2% of children experienced rollover crashes, but these contributed 1832 (28%) of 6570 child passenger fatalities. Among 56 crashes, 5 restrained young children were ejected, 4 in rollover crashes. Ejection of a toddler through the shoulder straps of a forward-facing child safety seat was the mechanism of ejection in three of the five cases. CONCLUSION Ejection from the vehicle is common (29%) among fatally injured children. Shoulder straps alone (as found in T-shield or overhead shield child seats) may not prevent the ejection of toddlers from child safety seats during rollovers.

Abstract
BACKGROUND Navajo motor vehicle mortality is the highest among the 12 Indian Health Service (IHS) administrative areas. In July 1988, the Navajo Nation enacted a primary enforcement safety belt use and a child restraint law. OBJECTIVE Assess the impact of the laws on the rate and severity of pediatric (0-19 years) motor vehicle injury resulting in hospitalizations in the Navajo Nation. METHODS Hospitalizations associated with motor vehicle related injury discharges were identified by International Classification of Diseases, 9th revision, CM E codes, 810-825 (.0,.1) from the Navajo IHS hospital discharge database. Age specific rates for the period before the law, 1983-88, were compared with those after enactment and enforcement, 1991-95. Severity of injury, measured by the abbreviated injury scale (AIS) score and new injury severity score (NISS), was determined with ICDMAP-90 software. Wilcoxon rank sum and chi(2) tests were used for analysis. RESULTS Discharge rates (SE) for motor vehicle injury (per 100 000) decreased significantly in all age groups: 0-4 years (62 (7) to 28 (4)), 5-11 years (55.3 (6) to 26 (4)), and 15-19 years (139 (14) to 68 (7)); p=0.0001. In children 0-4 years, the median AIS score decreased from 1.5 (1,3) (25th, 75th centile) to 1 (1,2), p=0.06, and the median NISS decreased from 3.5 (1,9) to 2 (1,5), p=0.07. The proportion of children with NISS scores >4 decreased significantly for the 0-4 year age group (p=0.03). CONCLUSIONS Concurrent with enactment of the Navajo Nation occupant and child restraint laws there was a reduction in the rate of motor vehicle related hospital discharges for children. Severity of injury declined in very young Navajo children. The effect of enactment and enforcement of this Native American child occupant restraint law may serve as an example of an effective injury control effort directed at Native American children.

Abstract
BACKGROUND/PURPOSE The United States Consumer Product Safety Commission (USCPSC) recently has reported a significant number of injuries and deaths in the home related to televisions (TV) falling on children. To date, little is known regarding the significance of this mechanism of injury in childhood trauma. The current investigation was designed to examine the risk factors, spectrum of injuries, and operative intervention required in children injured by falling televisions. METHODS The records of all patients 0 to 16 years of age with television-related injuries and entered in the Pennsylvania Trauma Outcome Study (PTOS) between 1989 and 1999 were reviewed. The authors examined Glascow coma scale (GCS), injury severity score (ISS), length of hospital stay (LOS), major injuries sustained, and operative procedures performed. Fourteen of the children in the PTOS were seen at the Benedum Pediatric Trauma Center at the Children's Hospital of Pittsburgh. In these 14 children, a review of the medical records was performed for a detailed description of the accident scenario. RESULTS Forty-three children sustained television-related injuries during this period. Nearly 56% of these children were </= years; 60% were boys. The mortality rate was 11% with 80% of the deaths occurring in children </= years. Furthermore, these children sustained the highest ISS and LOS and lowest GCS. The majority of injuries sustained were head injuries followed by extremity fractures. Dressers and standard television stands were common supportive structures from which the television fell and injured the child. CONCLUSIONS These data show that the majority of television-related injuries occur in toddlers (1 to 3 years) who were left unattended at home. The mortality rate was surprisingly high, especially in children </= years from subsequent head injuries. Prevention focused on improved public awareness of this danger, and modified design of the standard support structures can decrease the number of injuries, which will benefit children overall.

Abstract
OBJECTIVES The objective of this study was to compare the injuries and outcomes of ejected victims who reached a Level I trauma center with nonejected MVC occupants. METHODS Data from 6,909 MVC victims admitted to a Level I trauma center, over a 91/2-year period, were retrospectively reviewed. Three mutually exclusive groups were studied: ejected, nonejected nonrestrained, and nonejected restrained. RESULTS The patient distribution was as follows: ejected 6.4% (n = 443), nonrestrained 50.1% (n = 3,461), and restrained 43.5% (n = 3,005). Ejected patients were younger, required ICU care more frequently, and a higher percentage were males compared with nonrestrained or restrained patients. Injury Severity Score (ISS) and length of stay (LOS) were significantly higher in ejected patients. Ejected patients suffered more injuries per anatomic region, and had a higher number of severe injuries in the head and neck region. The overall in-hospital mortality was 3.9% (272/6,909), and 10.8% (48/443) for the ejected group. The incidence of restrained patients increased during the study period but was not associated with a change in the incidence of ejected patients. CONCLUSION Patients who were ejected after motor vehicle collisions were more severely injured and had a worse outcome than those not ejected. Efforts should be concentrated on enforcement and enactment of better seat belt laws, as well as the development of new strategies that will prevent ejection regardless of occupant behavior.
