Impact of COVID-19 pandemic on the dynamic of patients with oral and maxillofacial trauma: interrupted time-series analysis.

Oral and maxillofacial trauma is influenced by various factors, including regional characteristics and social background. Due to the coronavirus disease 2019 (COVID-19) pandemic, a state of emergency was declared in Japan in March 2020. In this study, we aimed to examine the dynamics of patients with oral and maxillofacial trauma over a 12-years period using interrupted time-series (ITS) analysis. Patients were examined at the Shimane University Hospital, Maxillofacial Trauma Center from April 2012 to April 2023. In addition to general patient characteristics, data regarding the type of trauma and its treatment were obtained from 1203 patients (770 men and 433 women). Group comparisons showed significant differences in age, trauma status, method of treatment, referral source, route, and injury occasion. ITS analysis indicated significant changes in combined nasal fractures, non-invasive reduction, and sports injuries (P < 0.05), suggesting COVID-19 significantly impacted oral and maxillofacial trauma dynamics. A pandemic of an infectious disease may decrease the number of minor trauma cases but increase the number of injuries from outdoor activities, resulting in no overall change in the dynamics of the number of trauma patients. Medical systems for oral and maxillofacial trauma should be in place at all times, independent of infectious disease pandemics.

Follow-up after major traumatic injury: a survey of services in Australian and New Zealand public hospitals.

BACKGROUND: Increased survival from traumatic injury has led to a higher demand for follow-up care when patients are discharged from hospital. It is currently unclear how follow-up care following major trauma is provided to patients, and how, when, and to whom follow-up services are delivered. The aim of this study was to describe the current follow-up care provided to patients and their families who have experienced major traumatic injury in Australia and New Zealand (ANZ). METHODS: Informed by Donabedian's 'Evaluating the Quality of Medical Care' model and the Institute of Medicine's Six Domains of Healthcare Quality, a cross-sectional online survey was developed in conjunction with trauma experts. Their responses informed the final survey which was distributed to key personnel in 71 hospitals in Australia and New Zealand that (i) delivered trauma care to patients, (ii) provided data to the Australasian Trauma Registry, or (iii) were a Trauma Centre. RESULTS: Data were received from 38/71 (53.5%) hospitals. Most were Level 1 trauma centres (n = 23, 60.5%); 76% (n = 16) follow-up services were permanently funded. Follow-up services were led by a range of health professionals with over 60% (n = 19) identifying as trauma specialists. Patient inclusion criteria varied; only one service allowed self-referral (3.3%). Follow-up was within two weeks of acute care discharge in 53% (n = 16) of services. Care activities focused on physical health; psychosocial assessments were the least common. Most services provided care for adults and paediatric trauma (60.5%, n = 23); no service incorporated follow-up for family members. Evaluation of follow-up care was largely as part of a health service initiative; only three sites stated evaluation was specific to trauma follow-up. CONCLUSION: Follow-up care is provided by trauma specialists and predominantly focuses on the physical health of the patients affected by major traumatic injury. Variations exist in terms of patient selection, reason for follow-up and care activities delivered with gaps in the provision of psychosocial and family health services identified. Currently, evaluation of trauma follow-up care is limited, indicating a need for further development to ensure that the care delivered is safe, effective and beneficial to patients, families and healthcare organisations.

Demographic and injury trends for car crash casualties hospitalized in Level I Trauma centers over two decades: data from the National Trauma Registry.

BACKGROUND: During the past two decades, there have been many changes in automotive and medical technologies, road infrastructure, trauma systems, and demographic changes which may have influenced injury outcomes. The aim of this study was to examine injury trends among traffic casualties, specifically private car occupants, hospitalized in Level I Trauma Centers (TC). METHODS: A retrospective cohort study was performed based on data from the Israel National Trauma Registry. The data included occupants of private cars hospitalized in all six Level I TC due to a traffic collision related injury between January 1, 1998 and December 31, 2019. Demographic, injury and hospitalization characteristics and in-hospital mortality were analyzed. Chi-squared (X2) test, multivariable logistic regression models and Spearman's rank correlation were used to analyze injury data and trends. RESULTS: During the study period, 21,173 private car occupants (14,078 drivers, 4,527 front passengers, and 2,568 rear passengers) were hospitalized due to a traffic crash. The percentage of females hospitalized due to a car crash increased from 37.7% in 1998 to 53.7% in 2019. Over a twofold increase in hospitalizations among older adult drivers (ages 65+) was observed, from 6.5% in 1998 to 15.7% in 2018 and 12.6% in 2019. While no increase was observed for severe traumatic brain injury, a statistically significant increase in severe abdominal and thoracic injuries was observed among the non-Jewish population along with a constant decrease in in-hospital mortality. CONCLUSIONS: This study provides interesting findings regarding injury and demographic trends among car occupants during the past two decades. Mortality among private car occupant casualties decreased during the study period, however an increase in serious abdominal and thoracic injuries was identified. The results should be used to design and implement policies and interventions for reducing injury and disability among car occupants.

Level One Trauma Center Proliferation May Worsen Patient Outcomes.

BACKGROUND: From 2013 to 2020, Arizona state trauma system expanded from seven to thirteen level 1 trauma centers (L1TCs). This study utilized the state trauma registry to analyze the effect of L1TC proliferation on patient outcomes. METHODS: Adult patients age≥15 in the state trauma registry from 2007-2020 were queried for demographic, injury, and outcome variables. These variables were compared across the 2 time periods: 2007-2012 as pre-proliferation (PRE) and 2013-2020 as post-proliferation (POST). Multivariate logistic regression was performed to assess independent predictors of mortality. Subgroup analyses were done for Injury Severity Score (ISS)≥15, age≥65, and trauma mechanisms. RESULTS: A total of 482,896 trauma patients were included in this study. 40% were female, 29% were geriatric patients, and 8.6% sustained penetrating trauma. The median ISS was 4. Inpatient mortality overall was 2.7%. POST consisted of more female, geriatric, and blunt trauma patients (P < .001). Both periods had similar median ISS. POST had more interfacility transfers (14.5% vs 10.3%, P < .001). Inpatient, unadjusted mortality decreased by .5% in POST (P < .001). After adjusting for age, gender, ISS, and trauma mechanism, being in POST was predictive of death (OR: 1.4, CI:1.3-1.5, P < .001). This was consistent across all subgroups except for geriatric subgroup, which there was no significant correlation. DISCUSSION: Despite advances in trauma care and almost doubling of L1TCs, POST had minimal reduction of unadjusted mortality and was an independent predictor of death. Results suggest increasing number of L1TCs alone may not improve mortality. Alternative approaches should be sought with future regional trauma system design and implementation.

Analyzing the Impact of Concomitant COVID-19 Infection on Outcomes in Trauma Patients.

BACKGROUND: The impact of COVID-19 infection at the time of traumatic injury remains understudied. Previous studies demonstrate that the rate of COVID-19 vaccination among trauma patients remains lower than in the general population. This study aims to understand the impact of concomitant COVID-19 infection on outcomes in trauma patients. METHODS: We conducted a retrospective cohort study of patients ≥18 years old admitted to a level I trauma center from March 2020 to December 2022. Patients tested for COVID-19 infection using a rapid antigen/PCR test were included. We matched patients using 2:1 propensity accounting for age, gender, race, comorbidities, vaccination status, injury severity score (ISS), type and mechanism of injury, and GCS at arrival. The primary outcome was inpatient mortality. Secondary outcomes included hospital length of stay (LOS), Intensive Care Unit (ICU) LOS, 30-day readmission, and major complications. RESULTS: Of the 4448 patients included, 168 (3.8%) were positive (COV+). Compared with COVID-19-negative (COV-) patients, COV+ patients were similar in age, sex, BMI, ISS, type of injury, and regional AIS. The proportion of White and non-Hispanic patients was higher in COV- patients. Following matching, 154 COV+ and 308 COV- patients were identified. COVID-19-positive patients had a higher rate of mortality (7.8% vs 2.6%; P = .010), major complications (15.6% vs 8.4%; P = .020), and thrombotic complications (3.9% vs .6%; P = .012). Patients also had a longer hospital LOS (median, 9 vs 5 days; P < .001) and ICU LOS (median, 5 vs 3 days; P = .025). CONCLUSIONS: Trauma patients with concomitant COVID-19 infection have higher mortality and morbidity in the matched population. Focused interventions aimed at recognizing this high-risk group and preventing COVID-19 infection within it should be undertaken.

Different but Equal: Outcomes of Prolonged Postanesthesia Care Unit Stay After Trauma Laparotomy.

INTRODUCTION: Hospital overcrowding is common and can lead to delays in intensive care unit (ICU) admission, resulting in increased morbidity and mortality in medical and surgical patients. Data on delayed ICU admission are limited in the postsurgical trauma cohort. Damage control laparotomy with temporary abdominal closure (DCL-TAC) for severely injured patients is often followed by an aggressive early resuscitation phase, usually occurring in the ICU. We hypothesized that patients who underwent DCL-TAC with initial postanesthesia care unit (PACU) stay would have worse outcomes than those directly admitted to ICU. METHODS: A retrospective chart review identified all trauma patients who underwent DCL-TAC at a level 1 trauma center over a 5 y period. Demographics, injuries, and resuscitation markers at 12 and 24 h were collected. Patients were stratified by location after index laparotomy (PACU versus ICU) and compared. Outcomes included composite morbidity and mortality. Multivariable logistic regression was performed. RESULTS: Of the 561 patients undergoing DCL-TAC, 134 (24%) patients required PACU stay due to ICU bed shortage, and 427 (76%) patients were admitted directly to ICU. There was no difference in demographics, injury severity score, time to resuscitation, complications, or mortality between PACU and ICU groups. Only 46% of patients were resuscitated at 24 h; 76% underwent eventual primary fascial closure. Under-resuscitation at 24 h (adjusted odds ratio [AOR] 0.55; 95% confidence interval [CI] 0.31-0.95, P = 0.03), increased age (AOR 1.04; 95% CI 1.02-10.55, P < 0.0001), and increased injury severity score (AOR 1.04; 95% CI 1.02-1.07, P < 0.0001) were associated with mortality on multivariable logistic regression. The median time in PACU was 3 h. CONCLUSIONS: PACU hold is not associated with worse outcomes in patients undergoing DCL-TAC. While ICU was designed for the resuscitation of critically ill patients, PACU is an appropriate alternative when an ICU bed is unavailable.

Defining Mild Traumatic Brain Injury: From Research Definition to Clinical Practice.

INTRODUCTION: Approximately 75% of traumatic brain injuries (TBIs) qualify as mild. However, there exists no universally agreed upon definition for mild TBI (mTBI). Consequently, treatment guidelines for this group are lacking. The Center for Disease Control (CDC), American College of Rehabilitation Medicine (ACRM), Veterans Affairs and Department of Defense (VA/DoD), Eastern Association for the Surgery of Trauma (EAST), and the University of Arizona's Brain Injury Guidelines (BIG) have each published differing definitions for mTBI. The aim of this study was to compare the ability of these definitions to correctly classify mTBI patients in the acute care setting. METHODS: A single-center, retrospective cohort study comparing the performance of the varying definitions of mTBI was performed at a Level I trauma center from August 2015 to December 2018. Definitions were compared by sensitivity, specificity, positive predictive value, negative predictive value, as well as overtriage and undertriage rates. Finally, a cost-savings analysis was performed. RESULTS: We identified 596 patients suffering blunt TBI with Glasgow Coma Scale 13-15. The CDC/ACRM definitions demonstrated 100% sensitivity but 0% specificity along with the highest rate of undertriage and TBI-related mortality. BIG 1 included nearly twice as many patients than EAST and VA/DoD while achieving a superior positive predictive value and undertriage rate. CONCLUSIONS: The BIG definition identified a larger number of patients compared to the VA/DoD and EAST definitions while having an acceptable and more accurate overtriage and undertriage rate compared to the CDC and ACRM. By eliminating undertriage and minimizing overtriage rates, the BIG maintains patient safety while enhancing the efficiency of healthcare systems. Using the BIG definition, a cost savings of $395,288.95-$401,263.95 per year could be obtained at our level 1 trauma facility without additional mortality.

Hemodynamic Deterioration of Trauma Patients Undergoing Interhospital Transfer.

INTRODUCTION: Organized trauma systems reduce morbidity and mortality after serious injury. Rapid transport to high-level trauma centers is ideal, but not always feasible. Thus, interhospital transfers are an important component of trauma systems. However, transferring a seriously injured patient carries the risk of worsening condition before reaching definitive care. In this study, we evaluated characteristics and outcomes of patients whose hemodynamic status worsened during the transfer process. METHODS: We conducted a retrospective cohort study using data from the Pennsylvania Trauma Outcomes Study database from 2011 to 2018. Patients were included if they had a heart rate ≤ 100 and systolic blood pressure ≥ 100 at presentation to the referring hospital and were transferred within 24 h. We defined hemodynamic deterioration (HDD) as admitting heart rate > 100 or systolic blood pressure < 100 at the receiving center. We compared demographics, mechanism of injury, injury severity, management, and outcomes between patients with and without HDD using descriptive statistics and multivariable regression analysis. RESULTS: Of 52,919 included patients, 5331 (10.1%) had HDD. HDD patients were more often moderately-severely injured (injury severity score 9-15; 40.4% versus 39.4%, P < 0.001) and injured via motor vehicle collision (23.2% versus 16.6%, P < 0.001) or gunshot wound (2.1% versus 1.3%, P < 0.001). HDD patients more often had extremity or torso injuries and after transfer were more likely to be transferred to the intensive care unit (35% versus 28.5%, P < 0.001), go directly to surgery (8.4% versus 5.9%, P < 0.001), or interventional radiology (0.8% versus 0.3%, P < 0.001). Overall mortality in the HDD group was 4.9% versus 2.1% in the group who remained stable. These results were confirmed using multivariable analysis. CONCLUSIONS: Interhospital transfers are essential in trauma, but one in 10 transferred patients deteriorated hemodynamically in that process. This high-risk component of the trauma system requires close attention to the important aspects of transfer such as patient selection, pretransfer management/stabilization, and communication between facilities.

Opportunity for Reduction of Intensive Care Unit Resource Utilization in Pediatric Blunt Liver and Spleen Injuries: A National Trauma Data Bank Analysis.

INTRODUCTION: Guidelines for blunt liver and spleen injury (BLSI) by the Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium (ATOMAC) emphasize hemodynamic stability over injury grade when considering non-operative management (NOM). In this study, we examined rates of intensive care unit (ICU) admission for children with isolated low-risk BLSI among US hospitals. METHODS: The National Trauma Data Bank (NTDB) was queried for patients ages 1-15 admitted between 2017 and 2019 with BLSI. Patients with penetrating injuries and/or concomitant non-abdominal injuries with AIS score ≥3 were excluded. Isolated BLSI was considered low-risk if the patient had normal admission vitals and did not require operative intervention. Primary outcomes measured were ICU admission, ICU length of stay (LOS), and overall LOS. RESULTS: 5777 patients ages 15 and under presented with isolated BLSI during the study period. 2031/5777 (35.2%) were considered low-risk. Low-risk patients had lower rates of ICU admission compared to high-risk patients (30.9% vs. 41.6%, p < 0.001) and had shorter ICU LOS (median 2 days vs. 2, p < 0.001) and shorter overall LOS (median 41 h vs. 54, p < 0.001). Pediatric verified and non-pediatric verified trauma centers had similar rates of ICU admission (36.8% vs. 38.9%, p = 0.11). CONCLUSION: Further work is needed to capture opportunities for reduction in ICU utilization in isolated BLSI. LEVEL OF EVIDENCE: III.

Variability in Standardized Mortality Rates Among Pediatric Traumatic Brain Injury Patients: A Comparative Analysis of Trauma Centers.

INTRODUCTION: Traumatic brain injury (TBI) causes significant morbidity and mortality in pediatric patients and care is highly variable. Standardized mortality ratio (SMR) summarizes the mortality rate of a specific center relative to the expected rates across all centers, adjusted for case-mix. This study aimed to evaluate variations in SMRs among pediatric trauma centers for TBI. METHODS: Patients aged 1-18 diagnosed with TBI within the National Trauma Data Bank (NTDB) from 2017 to 2019 were included. Center-specific SMRs and 95% confidence intervals identified centers with mortality rates significantly better or worse than the median SMR for all centers. RESULTS: 316 centers with 10,598 patients were included. SMRs were risk-adjusted for patient risk factors. Unadjusted mortality ranged from 16.5 to 29.5%. Three centers (1.5%) had significantly better SMR (SMR <1) and three centers (1.5%) had significantly worse SMR (SMR >1). Significantly better centers had a lower proportion of neurosurgical intervention (2.4% vs. 11.8%, p < 0.001), a higher proportion of supplemental oxygen administration (93.7% vs. 83.5%, p = 0.004) and venous thromboembolism prophylaxis (53.2% vs. 40.6%, p < 0.001) compared to significantly worse centers. CONCLUSIONS: This study identified centers that have significantly higher and lower mortality rates for pediatric TBI patients relative to the overall median rate. These data provide a benchmark for pediatric TBI outcomes and institutional quality improvement. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective Comparative Study.

Evaluating Health Literacy in Families of Injured Children: A Prospective Observational Cohort Study at a Level One Pediatric Trauma Center.

BACKGROUND: Low health literacy (HL) has been associated with poor health outcomes in children. Optimal recovery after pediatric injury requires caregiver participation in complicated rehabilitative and medical aftercare. We aimed to quantify HL among guardians of injured children and identify factors associated with low HL of guardians. METHODS: A prospective observational cohort study was conducted to evaluate the HL using the Newest Vital Sign™ of guardians of injured children (≤18 years) admitted to a level 1 pediatric trauma center. Patient and guardian characteristics were compared across levels of HL using univariate statistics. We conducted multivariable logistic regression to identify factors independently-associated with low HL. RESULTS: A sample of 95 guardian-child dyads were enrolled. The majority of guardians had low HL (n = 52, 55%), followed by moderate HL (n = 36, 38%) and high HL (n = 7, 7%). Many families received public benefits (n = 47, 49%) and 12 guardians (13%) had both housing and employment insecurity. Guardians with low HL were significantly more likely to have insecure housing and not have completed any college. CONCLUSION: The majority of injured children had a primary guardian with low HL. Pediatric trauma centers should consider screening for low HL to ensure that families have adequate post-discharge support. LEVEL OF EVIDENCE: Level 3.

Self-harm presentations to hospital trauma centre emergency departments during the first year of the COVID-19 pandemic.

The COVID-19 pandemic raised concerns regarding increased suicide-related behaviours. We compared characteristics and counts of Emergency Department (ED) presentations for self-harm, an important suicide-related outcome, during versus prior to the pandemic's first year. We included patients presenting with self-harm to the ED of two trauma centres in Toronto, Canada. Time series models compared intra-pandemic (March 2020-February 2021) presentation counts to predictions from pre-pandemic data. The self-harm proportion of ED presentations was compared between the intra-pandemic period and preceding three years. A retrospective chart review of eligible patients seen from March 2019-February 2021 compared pre- vs. intra-pandemic patient and injury characteristics. While monthly intra-pandemic self-harm counts were largely within expected ranges, the self-harm proportion of total presentations increased. Being widowed (OR=9.46; 95 %CI=1.10-81.08), employment/financial stressors (OR=1.65, 95 %CI=1.06-2.58), job loss (OR=3.83; 95 %CI=1.36-10.76), and chest-stabbing self-harm (OR=2.50; 95 %CI=1.16-5.39) were associated with intra-pandemic presentations. Intra-pandemic self-harm was also associated with Intensive Care Unit (ICU) admission (OR=2.18, 95 %CI=1.41-3.38). In summary, while the number of self-harm presentations to these trauma centres did not increase during the early pandemic, their proportion was increased. The association of intra-pandemic self-harm with variables indicating medically severe injury, economic stressors, and being widowed may inform future suicide and self-harm prevention strategies.

Epidemiology and factors associated with mortality among pediatric major trauma patients in Nova Scotia: A 17-year retrospective analysis.

BACKGROUND: Major traumatic injury in the pediatric population requires further evaluation to improve patient outcomes. Relatively few Canadian studies have investigated pediatric trauma using population-based data. Our objectives were to describe the epidemiology of pediatric major trauma in Nova Scotia and identify factors associated with in-hospital mortality. METHODS: Retrospective cohort study of pediatric major trauma patients (age <18 years) injured in Nova Scotia over a 17-year period (April 2001-March 2018). Data were collected from the Nova Scotia Trauma Registry. Characteristics were compared between patient subgroups using t-tests, chi-square analyses and Fisher's exact test. Temporal trends were evaluated using the Mann-Kendall test. Incidence and mortality rates were mapped using ArcGIS Pro. A multivariate logistic regression model was created to assess for factors associated with in-hospital mortality. RESULTS: A total of 1258 injuries were observed over the 17-year study period. The incidence of pediatric major trauma was 41.7 per 100,000 person-years. Most patients were male (819/1258; 65.1 %) and resided in urban areas (764/1258; 60.7 %). Blunt trauma accounted for 86.2 % (1084/1258) of injuries, and motor vehicle collisions were the most common cause (448/1258; 35.6 %). Incidence and mortality rates were highest in the 15-17 year age group, with a trend towards increasing incidence among females (p = 0.011). Mortality was 17.2 % (217/1258) of patients; 10.9 % (137/1258) died pre-hospital. No trends were detected in mortality rates. The regression model showed increased odds of in-hospital mortality for every point increase in the ISS (OR 1.05; 95 % CI 1.02 to 1.09) and for every unit decrease in scene GCS (OR 0.63; 95 % CI 0.56-0.71). Rural patients were 2 times more likely to die in-hospital versus urban patients (OR 2.40; 95 % CI 1.01-5.69), and patients injured at home were 6 times more likely to die compared to those injured in other locations (OR 6.19; 95 % CI 1.01-38.11). CONCLUSION: Pediatric trauma remains a major public health issue in Canada and beyond. Greater efforts are required to expand our understanding of trauma epidemiology and develop targeted injury prevention strategies, especially for rural inhabitants.

Reducing low-value interhospital transfers for mild traumatic brain injury.

BACKGROUND: The modified Brain Injury Guidelines (mBIG) were developed to stratify traumatic brain injuries (TBIs) and improve health care utilization by selectively requiring repeat imaging, intensive care unit admission, and neurosurgical (NSG) consultation. The goal of this study is to assess safety and potential resource savings associated with the application of mBIG on interhospital patient transfers for TBI. METHODS: Adult patients with TBI transferred to our Level I trauma center from January 2017 to December 2022 meeting mBIG inclusion criteria were retrospectively stratified into mBIG1, mBIG2, and mBIG3 based on initial clinicoradiological factors. At the time, our institution routinely admitted patients with TBI and intracranial hemorrhage (ICH) to the intensive care unit and obtained a repeat head computed tomography with NSG consultation, independent of TBI severity or changes in neurological examination. The primary outcome was progression of ICH on repeat imaging and/or NSG intervention. Secondary outcomes included length of stay and financial charges. Subgroup analysis on isolated TBI without significant extracranial injury was performed. RESULTS: Over the 6-year study period, 289 patients were classified into mBIG1 (61; 21.1%), mBIG2 (69; 23.9%), and mBIG3 (159; 55.0%). Of mBIG1 patients, 2 (2.9%) had radiological progression to mBIG2 without clinical decline, and none required NSG intervention. Of mBIG2, 2 patients (3.3%) progressed to mBIG3, and both required NSG intervention. More than 35% of transferred patients had minor isolated TBI. For mBIG1 and mBIG2, the median hospitalization charges per patient were $152,296 and $149,550, respectively, and the median length of stay was 4 and 5 days, respectively, with the majority downgraded from the intensive care unit within 48 hours. CONCLUSION: Clinically significant progression of ICH occurred infrequently in 1.5% of patients with mBIG1 and mBIG2 injuries. More than 35% of interfacility transfers for minor isolated TBI meeting mBIG1 and 2 criteria are low value and may potentially be safely deferred in an urban health care setting. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Discrepancies in Mass Shootings and Access to Trauma Care Across the United States, 2014-2018.

INTRODUCTION: The United States has one of the highest rates of gun violence and mass shootings. Timely medical attention in such events is critical. The objective of this study was to assess geographic disparities in mass shootings and access to trauma centers. METHODS: Data for all Level I and II trauma centers were extracted from the American College of Surgeons and the Trauma Center Association of America registries. Mass shooting event data (4+ individuals shot at a single event) were taken from the Gun Violence Archive between 2014 and 2018. RESULTS: A total of 564 trauma centers and 1672 mass shootings were included. Ratios of the number of mass shootings vs trauma centers per state ranged from 0 to 11.0 mass shootings per trauma center. States with the greatest disparity (highest ratio) included Louisiana and New Mexico. CONCLUSION: States in the southern regions of the US experience the greatest disparity due to a high burden of mass shootings with less access to trauma centers. Interventions are needed to increase access to trauma care and reduce mass shootings in these medically underserved areas.

Changes in Patterns of Trauma Injuries in the Dakotas Region During the COVID-19 Pandemic.

BACKGROUND: The aim of this study is to compare impact of COVID-19 on trauma volume and characteristics on a set of trauma centers with a rural catchment area. The COVID-19 pandemic has affected different parts of the country quite differently, both in case volume and in local responses. State-wide responses have varied considerably, including variations in local mask mandates, school closures, and social distancing measures. METHODS: This was a retrospective trauma registry review of patients who were admitted to three of the tertiary care trauma centers in North and South Dakota between 2014 through 2022. RESULTS: In the analysis of 36,397 patients, we found a significant increase in trauma patient volume during the COVID-19 pandemic, with an increased percentage of patients presenting with a mechanism of injury secondary to abuse or assault. This increase in patient volume continued to rise during 2021 and 2022. CONCLUSIONS: Our study demonstrates how the COVID-19 pandemic impacted trauma center admissions in the rural and frontier Midwest differently from more urban areas, and the importance of including a variety of settings in trauma research.

Epidemiology of Craniomaxillofacial Fractures Over a 5-year Period at a Midwestern Level 1 Trauma Center Serving a Large Rural Population.

BACKGROUND: Though the epidemiology of craniomaxillofacial (CMF) fractures has been well documented at urban hospitals, the characteristics of these fractures in rural hospitals have not been well studied. PURPOSE: The purpose of this study is to report on the epidemiology of CMF fractures at a regional Level 1 trauma center serving a large rural population in central Illinois. STUDY DESIGN, SETTING, SAMPLE: This is a retrospective cohort study at a community-based regional tertiary referral center that serves a predominantly rural population. Inclusion criteria comprised patients with radiologically confirmed CMF fractures between 2015 and 2019. Patients with incomplete medical records were excluded. PREDICTOR VARIABLE: Predictor variables included demographics (age, admission source, race, and sex) and etiology of CMF fracture (assault/domestic violence, all-terrain vehicle/off-road, falls, farm-related, motor vehicle collisions, gunshot wound, and others). MAIN OUTCOME VARIABLE: The primary outcome variable was the CMF anatomic location including nasal bone, orbit, mandible, malar/maxillary, and other CMF fractures. COVARIATES: The covariates are not applicable. ANALYSES: Descriptive statistics were used to summarize a sample of the population characteristics. Wilcoxon ranked sign tests and χ2 tests of independence were used to assess for statistically significant associations between select variables of interest. Statistical significance was defined as P < .05. RESULTS: Between 2015 and 2019, a total of 2,334 patients presented to the emergency department with a CMF fracture. After applying the inclusion/exclusion criteria, the final sample was composed of 1,844 patients for the management of 2,405 CMF fractures. The majority of patients were male(62.0%) and young adults (aged 18-39) had the highest number of CMF fractures (819) relative to all other age groups. The most common fracture etiology was fall(37.3%), and nasal bone fractures represented the most common fracture location(41.6%). χ2 analyses revealed statistically significant associations between the anatomic location of CMF fracture incurred, and differing categories of age, admission source, race, sex, and etiology. CONCLUSION AND RELEVANCE: Our study shows that patients seen at our Midwestern Level 1 trauma center are more likely to present with nasal bone and malar/maxillary fractures due to falls. In studies based in urban centers, patients are likely to present with orbital and mandibular fractures due to falls and assault.

Predictors of Receiving Mental Health Services in Trauma Patients With Positive Drug Screen.

INTRODUCTION: Initial interaction with health care system presents an important opportunity to provide substance use disorder (SUD) rehabilitation in the form of mental health services (MHSs). This study aims to identify predictors of receipt of MHSs among adult trauma patients with SUD and positive drug screen. METHODS: In this analysis of 2017-2021 American College of Surgeons-Trauma Quality Improvement Program (ACS TQIP), adult(≥18 y) patients with SUD and positive drug screen who survived the hospital admission were included. Outcomes measure was the receipt of MHS. Poisson regression analysis with clustering by facility was performed to identify independent predictors of receipt of MHS. RESULTS: 128,831 patients were identified of which 3.4% received MHS. Mean age was 41 y, 76% were male, 63% were White, 25% were Black, 12% were Hispanic, and 82% were insured. Median injury severity score was 9, and 54% were managed at an ACS level I trauma center. On regression analysis, female gender (aOR = 1.17, 95% CI = 1.09-1.25), age ≥65 y (aOR = 0.98, 95% CI = 0.97-0.99), White race (aOR = 1.37, 95% CI = 1.28-1.47), Hispanic ethnicity (aOR = 0.84, 95% CI = 0.76-0.93), insured status (aOR = 1.22, 95% CI = 1.13-1.33), and management at ACS level I trauma centers (aOR = 1.47, 95% CI = 1.38-1.57) were independent predictors of receipt of MHS. CONCLUSIONS: Race, ethnicity, and socioeconomic factors predict the receipt of MHS in trauma patients with SUD and positive drug screens. It is unknown if these disparities affect the long-term outcomes of these vulnerable patients. Further research is warranted to expand on the contributing factors leading to these disparities and possible strategies to address them.

Application of the Geriatric Trauma Outcome Score in a Rural Setting.

OBJECTIVE: To retrospectively apply the Geriatric Trauma Outcome (GTO) score to the patient population of a rural South Central Appalachian level 1 trauma center and identify the potential utility of the GTO score in guiding goals of care discussions. METHODS: Trauma registry data was extracted for 5,627 patients aged 65+ from 2017 to 2021. GTO score was calculated for each patient. Descriptive statistics were calculated for age, Injury Severity Score (ISS), GTO score, receipt of red blood cells, discharge status, and code status. A simple logistic regression model was used to determine the relationship between GTO score and discharge status. The probability of mortality was then calculated using GTO score, and the distribution of code status among patients with ≤50, 51-75%, and >75% probability of mortality was examined. RESULTS: For every 10-point increase in GTO score, odds of mortality increased by 79% (OR = 1.79; P < .001). Patients had an estimated 50% probability of mortality with a GTO score of 156, 75% with 174, and 99% with a score of 234, respectively. Seventeen patients had a GTO score associated with >75% probability of mortality. Of those 17 patients, four retained a full code status. CONCLUSIONS: Our analysis demonstrates that the GTO score is a validated measure in a rural setting and can be an easily calculated metric to help determine a geriatric patient's probability of mortality following a trauma. The results of our study also found that GTO score can be used to inform goals of care discussions with patients.

Teamwork matters: The association between nontechnical skills and cardiac arrest in trauma patients presenting with hypotension.

BACKGROUND: The impact of trauma team dynamics on outcomes in injured patients is not completely understood. We sought to evaluate the association between trauma team function, as measured by a modified Trauma Non-Technical Skills assessment, and cardiac arrest in hypotensive trauma patients. We hypothesized that better team function is associated with a decreased probability of developing cardiac arrest. METHODS: Trauma video review was used to collect data from resuscitations of adult hypotensive trauma patients at 19 centers. Hypotension at emergency department presentation was defined as an initial systolic blood pressure <90 mm Hg or an initial systolic blood pressure ≥90 mm Hg followed by a systolic blood pressure <90 mm Hg within the first 5 minutes. Team dynamics were scored using a modified Trauma Non-Technical Skills assessment composed of 5 domains with combined scores ranging from 5 (best) to 15 (worst). Scores were compared between cardiac arrest/noncardiac arrest cases in the trauma bay. Logistic regression was used to evaluate the independent association between the Trauma Non-Technical Skills assessment and cardiac arrest. RESULTS: A total of 430 patients were included (median age 43 years [interquartile range: 29-61]; 71.8% male; 36% penetrating mechanism; median Injury Severity Score 20 [10-33]; 11% experienced cardiac arrest in trauma bay). The median total Trauma Non-Technical Skills assessment score was 7 (6-9), higher in patients who experienced cardiac arrest in the trauma bay (9 [6-10] vs 7 [6-9]; P = .016). This association persisted after controlling for age, sex, mechanism, injury severity, initial systolic blood pressure, and initial Glasgow Coma Scale score (adjusted odds ratio: 1.28; 95% confidence interval:1.11-1.48; P < .001), indicating a ∼3% higher predicted probability of cardiac arrest per Trauma Non-Technical Skills point. CONCLUSION: Better team function is independently associated with a decreased probability of cardiac arrest in trauma patients presenting with hypotension. This suggests that trauma team training may improve outcomes in peri-arrest patients.
