Analysis of serious trauma injury patterns in Navarre (Spain) (2010-2019)

The aim of this study is to describe major trauma cases in Navarre and analyze differences based on mortality groups, sex, and mode of injury. Cross-sectional study of major traumas (severity =3) registered in Navarre between 2010 and 2019. We analyzed the type of trauma, intentionality, the mode of injury, and the affected anatomical area. The odds ratio for major trauma associated with different variables was calculated. The study included 2,609 patients; mean age was 54.7 years (0-101) and 70.9% were male. A predominance of accidental (84%) / blunt (94.7%) major traumas was recorded, primarily resulting from falls (46.5%) and car accidents (18.4%). Women experienced more falls and pedestrian accidents, while men had more motorcycle, bicycle, knife/firearm accidents, and contusions. Most major traumas affected the head and thorax. Head trauma was significantly more common in deceased individuals and women, while thoracic trauma was more frequent in patients who died on-site and in men. Head injuries were caused by falls from low heights and firearms, whereas thoracic injuries resulted from car accidents and falls from height. The risk of major trauma decreased with age; deceased patients were between two and three times more likely to present lesions in all anatomical areas. Gender differences are observed in intentionality, type, and mode of injury. Head and thoracic injuries are potentially life-threatening and abdominal and extremity/pelvic ring injuries are associated with early deaths. This suggests that the extent and severity of these injuries complicate treatment and management.

Sex-related disparities in vehicle crash injury and hemodynamics.

Multiple studies evaluate relative risk of female vs. male crash injury; clinical data may offer a more direct injury-specific evaluation of sex disparity in vehicle safety. This study sought to evaluate trauma injury patterns in a large trauma database to identify sex-related differences in crash injury victims. Data on lap and shoulder belt wearing patients age 16 and up with abdominal and pelvic injuries from 2018 to 2021 were extracted from the National Trauma Data Bank for descriptive analysis using injuries, vital signs, International Classification of Disease (ICD) coding, age, and injury severity using AIS (Abbreviated Injury Scale) and ISS (Injury Severity Score). Multiple linear regression was used to assess the relationship of shock index (SI) and ISS, sex, age, and sex*age interaction. Regression analysis was performed on multiple injury regions to assess patient characteristics related to increased shock index. Sex, age, and ISS are strongly related to shock index for most injury regions. Women had greater overall SI than men, even in less severe injuries; women had greater numbers of pelvis and liver injuries across severity categories; men had greater numbers of injury in other abdominal/pelvis injury regions. Female crash injury victims' tendency for higher (AIS) severity of pelvis and liver injuries may relate to how their bodies interact with safety equipment. Females are entering shock states (SI > 1.0) with lesser injury severity (ISS) than male crash injury victims, which may suggest that female crash patients are somehow more susceptible to compromised hemodynamics than males. These findings indicate an urgent need to conduct vehicle crash injury research within a sex-equity framework; evaluating sex-related clinical data may hold the key to reducing disparities in vehicle crash injury.

Differences in Trauma Injury Patterns and Severity Between Intentional and Accidental Falls From a Height: A Japanese Nationwide Trauma Database Study.

BackgroundFall from a height is a common cause of trauma requiring emergency care; in many cases, the trauma team needs to urgently develop the initial treatment strategy. The mechanism of injury (intentional or accidental) is an important factor in predicting trauma patterns and severity. We aimed to describe how the severity of injuries in each body region contributes to overall trauma severity and skeletal trauma patterns in intentional and accidental falls.MethodsData accumulated between January 1, 2004 and May 31, 2019 were obtained from a nationwide trauma database. Patients aged ≥18 years and injured by falls from a height were included. The median Abbreviated Injury Scale (AIS) score for the Injury Severity Score (ISS) for each body region (region 1: head, face, and neck; region 2: thorax; region 3: abdomen; region 4: lower extremity and pelvis; and region 5: upper extremity) was investigated. Skeletal injury patterns were classified into four groups: group I (intentional/severe), group II (accidental/severe), group III (intentional/not severe), and group IV (accidental/not severe). Severe trauma was defined as a trauma with an ISS of 16 or more. The groups were compared using the chi-square test and Mann-Whitney U test.ResultsAmong the 342,263 patients enrolled in the database, 28,409 met the inclusion criteria: 6,812 in group I, 11,754 in group II, 2,384 in group III, and 7,459 in group IV. The intentional fall group showed an increase in the AIS score for region 4 as the ISS increased, whereas the accidental fall group showed an increase in the AIS score for region 1. Both groups showed an increase in the AIS score for region 2 as the ISS increased. The intentional fall group had a higher proportion of fractures in the lower extremities and pelvis than the accidental fall group.ConclusionsThere were differences in trauma patterns and trauma severity levels between patients who experienced intentional and accidental falls from a height. Our findings provide a comprehensive understanding of this topic. Further studies are required to assess the usefulness of our findings for the development of initial treatment strategies at the ED.

TRAUMATIC INJURIES PRESENTING TO THE EMERGENCY DEPARTMENT IN A LEVEL-1

Objective: Traumas are a major health concern in Saudi Arabia, and they can result in many injuries burden. Furthermore, it is one of the main causes of morbidity and mortality in the worldwide. As a result, the awareness of physicians who are the first to see trauma is critical. The study aims to determine the prevalence of traumatic injuries in emergency department. Methods: It is a retrospective study that used the trauma registry of the King Abdulaziz Medical City, Trauma Center to analyze data from January 2015 to January 2020 on trauma patients admitted to the hospital. Demographic features, date and time of admission, type and mechanism of injury, patterns of transportation, and rates of severity were analyzed. p<0.05 was considered statistically significant. Results: A total of 6095 patients, the majority were male (79.9%). Blunt trauma was the most prevalent type of injury (85.7%, p<0.001). A motor vehicle accident was the most prevalent mechanism of injury (37.5%). The highest proportion of trauma per age group was in the 21–30 year age group (28.7%). The mean of Injury Severity Score in the current study was found to be 10.7 and the injured patients’ Glasgow coma scale (GCS) mean was 13.4. The ICU stay average was 3.6 days while the hospital stay was 17.2 days. Conclusion: This study revealed trauma injury patterns in a tertiary hospital in Riyadh, Saudi Arabia, demonstrating the local variation across genders, age groups, types of injury, and mechanisms of injury. These demographic data would be useful for local resourcing of the healthcare system to full impact.

Education Empowers Emergency Department Nurses During Pediatric Traumas.

In January 2017, the Emergency Trauma Advocate (ETA) program was piloted at our Level 1 trauma center to promote patient advocacy, particularly in pediatric patients. The goal was to empower emergency department nurses by improving their knowledge base through interactive didactic sessions. This study reviews the preliminary findings of the program. Surveys were administered after each teaching session to participating ETA nurses to determine their personal academic interests and how to improve the program. We then performed a retrospective review of pediatric trauma admissions from January 2017 through April 2017 to delineate the most common injury patterns. Survey responses demonstrated the greatest nursing interest in learning critical care (n = 11), orthopedic management (n = 11), and neurosurgical trauma education (n = 9). During this study period, 113 pediatric patients arrived and had a mean age of 7.8 ± 5.2 years. The most common injury patterns were orthopedic (n = 38) and neurosurgical (n = 28), and 35 patients required critical care management. Bivariate analysis revealed a significant and positive relationship between injury frequency and educational interests (R = 98.8%, p = .0057). A nurse's interest in educational topics directly correlates with recent pediatric trauma injury patterns. Future work should focus on determining what impact the ETA program has had on pediatric outcomes.

Phagocytizing activity of PMN from severe trauma patients in different post-traumatic phases during the 10-days post-injury course

ObjectivePhagocytizing leukocytes (granulocytes and monocytes) play a fundamental role in immunological defense against pathogens and clearance of cellular debris after tissue injury due to trauma. According to the “two-hit hypothesis”, phagocytes become primed due to/after trauma. Subsequently, a secondary stimulus may lead to their exaggerated response. This immune dysfunction can result in serious infectious complications, also depending on trauma injury pattern. Here, we investigated the phagocytizing capacity of leukocytes, and its correlation to trauma injury pattern. Material/methodsPeripheral whole blood was taken daily from 29 severely injured trauma patients (TP, Injury Severity Score, ISS≥28) for ten days (1–10) following admission to the emergency department (ED). Sixteen healthy volunteers served as controls (HV). Samples were incubated with opsonized Staphylococcus aureus labelled with pHrodo fluorescent reagent and the percentage of phagocytizing activity was assessed by flow cytometry. Abbreviated Injury Scales (AIS)≥3 of head, chest and extremities were used for injury pattern analysis. ResultsOverall distribution of active phagocytes (out of 100% phagocytizing leukocytes) in TP included granulocytes with 28.6±1.5% and monocytes with 59.3±1.9% at ED, and was comparable to HV (31.5±1.6% granulocytes and 60.1±1.6% monocytes). The percentage of phagocytizing granulocytes increased significantly after D2 (39.1±1.2%), while the percentage of phagocytizing monocytes (52.0±1.2%, p<0.05) decreased after D2. These changes persisted during the whole time course. Phagocytizing activity of granulocytes (27.9±2.8%) and monocytes (55.2±3.3%) was significantly decreased at ED compared to HV (42.4±4.1% and 78.1±3.1%, respectively). After D2 up to D10, phagocytizing activity was significantly enhanced in granulocytes. Phagocytizing activity of monocytes remained decreased on D1 and has risen continuously during the ten days time course to values comparable to HV. No significant differences in phagocytosis could be associated to certain injury pattern. ConclusionsOur data demonstrate that the increasing percentage of phagocytizing granulocytes may indicate their enhanced mobilization out of bone marrow persisting until post-injury day 10. Furthermore, an initially decreased phagocytizing activity of granulocytes is strongly increased in the 10-days post-injury course. The altered activity of phagocytes due to injury could not be linked to any trauma injury pattern, and emerged rather as a general characteristic of phagocytes after severe trauma.

Non-accidental Trauma Injury Patterns and Outcomes: A Single Institutional Experience

Non-accidental trauma (NAT) victims account for a significant percentage of our pediatric trauma population. We sought to better understand the injury patterns and outcomes of NAT victims who were treated at our level I pediatric trauma center. Trauma registry data were used to identify NAT victims between January 2008 and December 2012. Demographic data, injury severity, hospital course, and outcomes were evaluated. One hundred and eighty-eight cases of suspected NAT were identified. Children were mostly male and white. The median age was 1.1 years; the median Injury Severity Score was 9. Traumatic brain injuries, lower extremity fractures, and skull fractures were the most common injuries. Twenty-seven per cent required medical procedures; most were performed by orthopedic surgery. Twenty-four per cent required admission to the pediatric intensive care unit. The median length of stay was two days. The mortality rate was 9.6 per cent. We generated a hot spot map of our catchment area and identified areas of our state where NAT occurs at increased rates. NAT victims sustain significant morbidity and mortality. Due to the severity of injuries, pediatric trauma surgeons should be involved in the evaluation and management of these children. Much work is needed to prevent the death and disability incurred by victims of child abuse.

Defining Predictable Patterns of Craniomaxillofacial Injury in the Elderly: Analysis of 1,047 Patients

Currently, nearly 1 in 5 Americans is at least 60 years of age. Bone atrophy, decreased capacity for tissue repair, and chronic disease are known to influence fracture patterns and operative algorithms in this age group. This study presents craniofacial trauma injury patterns and treatment in an elderly population at a major urban trauma center. Patient records were retrospectively reviewed from February 1998 through December 2010. Patients at least 60 years of age who met the inclusion criteria for craniofacial fractures identified by International Classification of Diseases, Ninth Revision code review and confirmed by author review of available computed tomograms were studied. Demographic information, fracture type, concomitant injuries, and management were recorded. Of 11,084 patients presenting with facial fracture, 1,047 were older than 60 years. The most common mechanism of injury was falls (50%), and most patients were men (59%). Commonly fractured areas included the nose (n = 452, 43%), maxilla (316, 30%), zygoma (312, 30%), orbital floor (280, 27%), and mandible (186, 18%), with 51 patients (5%) having a concomitant basilar skull fracture. Inpatient mortality and length of stay were significantly increased compared with the nongeriatric population (P < .01), although only 5% of all fractures were treated operatively. Fractures in the elderly tend to be minimally displaced midfacial fractures that do not warrant surgical intervention. Despite conservative management, the elderly are hospitalized longer than their younger counterparts, have increased critical care needs, and have higher mortality. These data support national medical preparedness in anticipating the craniofacial trauma needs of the aging US population and can be used to update treatment algorithms for these patients.

Injury and Illness Encountered in Shenandoah National Park

There have been no studies to date exploring the nature of injuries and illness experienced by individuals in a National Park in the southeastern United States. The purpose of this study was to determine the incidence of such illnesses and injuries to visitors in Shenandoah National Park. This study was a retrospective review of the case incident reports from Shenandoah National Park from 2003 to 2007. Data obtained included age, sex, time and date report was received, medical symptoms, trauma type, location of injury, mechanism of injury, level of care, time to patient, time to disposition, disposition type, location, and activity at time of event. There were 159 total cases, corresponding to a reported incident rate of 2.7 persons reported injured or ill per 100 000 visitors to Shenandoah National Park. A total of 23.3% of all reported injuries occurred in persons less than 18 years of age. The most common reported adult injury was soft tissue injury, with the most common anatomical location being the distal lower extremity. The most common activity in which adults were involved at the time of the injury was hiking. Of the pediatric trauma cases, the most common mechanism of injury was a fall. Of the adult medical illnesses, the most common complaint was chest pain. The pattern of adult and pediatric trauma is consistent among several geographically different National Parks in the United States and represents an injury pattern that all wilderness/outdoor care providers need to be competent to treat. Among adult visitors, the most common medical complaint was chest pain, a complaint more prevalent at Shenandoah National Park compared to other parks. Knowing that trauma injury patterns are relatively similar to those of other parks but that medical illness is more locale specific can help health care providers tailor their resource allotment and health management protocols.
