Purpose: There is mounting evidence that surgical patients with COVID-19 have higher morbidity and mortality than patients without COVID-19. Infection is prevalent amongst the trauma population, but any effect of COVID-19 on trauma patients is unknown. We aimed to evaluate the effect of COVID-19 on a trauma population, hypothesizing increased mortality and pulmonary complications for COVID-19-positive (COVID) trauma patients compared to propensity-matched COVID-19-negative (non-COVID) patients. Methods: A retrospective analysis of trauma patients presenting to 11 Level-I and II trauma centers in California between 1/1/2019–6/30/2019 and 1/1/2020–6/30/2020 was performed. A 1:2 propensity score model was used to match COVID to non-COVID trauma patients using age, blunt/penetrating mechanism, injury severity score, Glasgow Coma Scale score, systolic blood pressure, respiratory rate, and heart rate. Outcomes were compared between the two groups. Results: A total of 20,448 trauma patients were identified during the study period. 53 COVID trauma patients were matched with 106 non-COVID trauma patients. COVID patients had higher rates of mortality (9.4% vs 1.9%, p = 0.029) and pneumonia (7.5% vs. 0.0%, p = 0.011), as well as a longer mean length of stay (LOS) (7.47 vs 3.28 days, p < 0.001) and intensive care unit LOS (1.40 vs 0.80 days, p = 0.008), compared to non-COVID patients. Conclusion: This multicenter retrospective study found increased rates of mortality and pneumonia, as well as a longer LOS, for COVID trauma patients compared to a propensity-matched cohort of non-COVID patients. Further studies are warranted to validate these findings and to elucidate the underlying pathways responsible for higher mortality in COVID trauma patients. [ABSTRACT FROM AUTHOR]

Background: COVID-19 related stay-at-home (SAH) orders created many economic and social stressors, possibly increasing the risk of drug/alcohol abuse in the community and trauma population. Objectives: Describe changes in alcohol/drug use in traumatically injured patients after SAH orders in California and evaluate demographic or injury pattern changes in alcohol or drug-positive patients. Methods: A retrospective analysis of 11 trauma centers in Southern California (1/1/2020-6/30/2020) was performed. Blood alcohol concentration, urine toxicology results, demographics, and injury characteristics were collected. Patients were grouped based on injury date – before SAH (PRE-SAH), immediately after SAH (POST-SAH), and a historical comparison (3/19/2019-6/30/2019) (CONTROL) – and compared in separate analyses. Groups were compared using chi-square tests for categorical variables and Mann-Whitney U tests for continuous variables. Results: 20,448 trauma patients (13,634 male, 6,814 female) were identified across three time-periods. The POST-SAH group had higher rates of any drug (26.2% vs. 21.6% and 24.7%, OR = 1.26 and 1.08, p <.001 and p =.035), amphetamine (10.4% vs. 7.5% and 9.3%, OR = 1.43 and 1.14, p <.001 and p =.023), tetrahydrocannabinol (THC) (13.8% vs. 11.0% and 11.4%, OR = 1.30 and 1.25, p <.001 and p <.001), and 3,4-methylenedioxy methamphetamine (MDMA) (0.8% vs. 0.4% and 0.2%, OR = 2.02 and 4.97, p =.003 and p <.001) positivity compared to PRE-SAH and CONTROL groups. Alcohol concentration and positivity were similar between groups (p >.05). Conclusion: This Southern California multicenter study demonstrated increased amphetamine, MDMA, and THC positivity in trauma patients after SAH, but no difference in alcohol positivity or blood concentration. Drug prevention strategies should continue to be adapted within and outside of hospitals during a pandemic. [ABSTRACT FROM AUTHOR]

Background: To improve care of geriatric trauma patients, the American College of Surgeons (ACS) Trauma Quality Improvement Program (TQIP) updated guidelines in 2021. Amid geriatrician shortages in Southern California, 2 Los Angeles County safety net hospitals were tasked with creating a strategy to meet geriatric trauma guidelines despite constrained resources. Methods: All trauma patients ≥ 60 years admitted to a safety net hospital in Southern California were enrolled without exclusions (August 2022-April 2023). Primary outcome was frailty screening with documentation to identify older trauma patients at a high risk for adverse outcomes. Results: Needs assessment discovered no standardized process to identify high-risk geriatric patients, no geriatric care guidelines, and no inpatient geriatric consultation service. An action plan composed of a resident-led frailty screen resulted in identification of high-risk patients. Overall, 217 patients met criteria. Ninety-six patients (44%) successfully underwent frailty screening. Frailty screening compliance increased over the study, beginning at 37% capture in the first month and increasing to 81% in the final study month. After achieving nearly uniform frailty screening, a form was developed for the EMR for ease of documentation, data capture/tracking, and compliance monitoring. Discussion: In this study, creativity, collaboration, and resourcefulness allowed TQIP guideline implementation at 2 county hospitals. A systematic process is now in place to identify and triage high-risk geriatric trauma patients based on frailty screen to receive inpatient medicine consultation for medical comorbidity optimization. Continued interdisciplinary and interfacility collaboration will be crucial for continued delivery of the optimal care to older injured patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: California issued stay-at-home (SAH) orders to mitigate COVID-19 spread. Previous studies demonstrated a shift in mechanisms of injuries (MOIs) and decreased length of stay (LOS) for the general trauma population after SAH orders. This study aimed to evaluate the effects of SAH orders on geriatric trauma patients (GTPs), hypothesizing decreased motor vehicle collisions (MVCs) and LOS., Methods: A post-hoc analysis of GTPs (≥65 years old) from 11 level-I/II trauma centers was performed, stratifying patients into 3 groups: before SAH (1/1/2020-3/18/2020) (PRE), after SAH (3/19/2020-6/30/2020) (POST), and a historical control (3/19/2019-6/30/2019) (CONTROL). Bivariate comparisons were performed., Results: 5486 GTPs were included (PRE-1756; POST-1706; CONTROL-2024). POST had a decreased rate of MVCs (7.6% vs 10.6%, P = .001; vs 11.9%, P < .001) and pedestrian struck (3.4% vs 5.8%, P = .001; vs 5.2%, P = .006) compared with PRE and CONTROL. Other mechanisms of injury, LOS, mortality, and operations performed were similar between cohorts. However, POST had a lower rate of discharge to skilled nursing facility (SNF) (20% vs 24.5%, P = .001; and 20% vs 24.4%, P = .001)., Conclusion: This retrospective multicenter study demonstrated lower rates of MVCs and pedestrian struck for GTPs, which may be explained by decreased population movement as a result of SAH orders. Contrary to previous studies on the generalized adult population, no differences in other MOIs and LOS were observed after SAH orders. However, there was a lower rate of discharge to SNF, which may be related to a lack of resources due to the COVID-19 pandemic, and thus potentially negatively impacted recovery of GTPs.Keywords., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The COVID-19 pandemic resulted in increased penetrating trauma and decreased length of stay (LOS) amongst the adult trauma population, findings important for resource allocation. Studies regarding the pediatric trauma population are sparse and mostly single-center. This multicenter study examined pediatric trauma patients, hypothesizing increased penetrating trauma and decreased LOS after the 3/19/2020 stay-at-home (SAH) orders., Methods: A multicenter retrospective analysis of trauma patients ≤ 17 years old presenting to 11 centers in California was performed. Demographic data, injury characteristics, and outcomes were collected. Patients were divided into three groups based on injury date: 3/19/2019-6/30/2019 (CONTROL), 1/1/2020-3/18/2020 (PRE), 3/19/2020-6/30/2020 (POST). POST was compared to PRE and CONTROL in separate analyses., Results: 1677 patients were identified across all time periods (CONTROL: 631, PRE: 479, POST: 567). POST penetrating trauma rates were not significantly different compared to both PRE (11.3 vs. 9.0%, p = 0.219) and CONTROL (11.3 vs. 8.2%, p = 0.075), respectively. POST had a shorter mean LOS compared to PRE (2.4 vs. 3.3 days, p = 0.002) and CONTROL (2.4 vs. 3.4 days, p = 0.002). POST was also not significantly different than either group regarding intensive care unit (ICU) LOS, ventilator days, and mortality (all p > 0.05)., Conclusions: This multicenter retrospective study demonstrated no difference in penetrating trauma rates among pediatric patients after SAH orders but did identify a shorter LOS., (© 2021.

Background: The rapid spread of coronavirus disease 2019 in the United States led to a variety of mandates intended to decrease population movement and "flatten the curve." However, there is evidence some are not able to stay-at-home due to certain disadvantages, thus remaining exposed to both coronavirus disease 2019 and trauma. We therefore sought to identify any unequal effects of the California stay-at-home orders between races and insurance statuses in a multicenter study utilizing trauma volume data., Methods: A posthoc multicenter retrospective analysis of trauma patients presenting to 11 centers in Southern California between the dates of January 1, 2020, and June 30, 2020, and January 1, 2019, and June 30, 2019, was performed. The number of trauma patients of each race/insurance status was tabulated per day. We then calculated the changes in trauma volume related to stay-at-home orders for each race/insurance status and compared the magnitude of these changes using statistical resampling., Results: Compared to baseline, there was a 40.1% drop in total trauma volume, which occurred 20 days after stay-at-home orders. During stay-at-home orders, the average daily trauma volume of patients with Medicaid increased by 13.7 ± 5.3%, whereas the volume of those with Medicare, private insurance, and no insurance decreased. The average daily trauma volume decreased for White, Black, Asian, and Latino patients with the volume of Black and Latino patients dropping to a similar degree compared to White patients., Conclusion: This retrospective multicenter study demonstrated that patients with Medicaid had a paradoxical increase in trauma volume during stay-at-home orders, suggesting that the most impoverished groups remain disproportionately exposed to trauma during a pandemic, further exacerbating existing health disparities., (Copyright © 2021 Elsevier Inc.

Background: The COVID-19 pandemic resulted in a statewide stay-at-home (SAH) order in California beginning March 19, 2020, forcing large-scale behavioral changes and taking an emotional and economic toll. The effects of SAH orders on the trauma population remain unknown. We hypothesized an increase in rates of penetrating trauma, gunshot wounds, suicide attempts, and domestic violence in the Southern California trauma population after the SAH order., Methods: A multicenter retrospective analysis of all trauma patients presenting to 11 American College of Surgeons levels I and II trauma centers spanning seven counties in California was performed. Demographic data, injury characteristics, clinical data, and outcomes were collected. Patients were divided into three groups based on injury date: before SAH from January 1, 2020, to March 18, 2020 (PRE), after SAH from March 19, 2020, to June 30, 2020 (POST), and a historical control from March 19, 2019, to June 30, 2019 (CONTROL). POST was compared with both PRE and CONTROL in two separate analyses., Results: Across all periods, 20,448 trauma patients were identified (CONTROL, 7,707; PRE, 6,022; POST, 6,719). POST had a significantly increased rate of penetrating trauma (13.0% vs. 10.3%, p < 0.001 and 13.0% vs. 9.9%, p < 0.001) and gunshot wounds (4.5% vs. 2.4%, p = 0.002 and 4.5% vs. 3.7%, p = 0.025) compared with PRE and CONTROL, respectively. POST had a suicide attempt rate of 1.9% and a domestic violence rate of 0.7%, which were similar to PRE (p = 0.478, p = 0.514) and CONTROL (p = 0.160, p = 0.618)., Conclusion: This multicenter Southern California study demonstrated an increased rate of penetrating trauma and gunshot wounds after the COVID-19 SAH orders but no difference in attempted suicide or domestic violence rates. These findings may provide useful information regarding resource utilization and a target for societal intervention during the current or future pandemic(s)., Level of Evidence: Epidemiological, level IV., (Copyright © 2020 Wolters Kluwer Health, Inc.

Background: Traumatic craniocervical dissociation (CCD) is the forcible dislocation of the skull from the vertebral column. Because most CCD patients die on scene, prognostication for those who arrive alive to hospital is challenging. The study objective was to determine if greater dissociation, based on radiologic measurements of CCD, is predictive of in-hospital mortality among patients surviving to the emergency department., Methods: All trauma patients arriving to our Level 1 trauma center (January 2008 to April 2019) with CCD were retrospectively identified and included. Transfers and patients without computed tomography head/cervical spine were excluded. Study patients were dichotomized into groups based on in-hospital mortality. Radiologic measurements of degree of CCD were performed based on the index computed tomography scan by an attending radiologist with Emergency Radiology fellowship training. Measurements were compared between patients who died in-hospital versus those who survived., Results: After exclusions, 36 patients remained: 12 (33%) died and 24 (67%) survived. Median age was 55 years (30-67 years) versus 44 (20-61 years) (p = 0.199). Patients who died had higher Injury Severity Score (39 [31-71] vs. 27 [14-34], p = 0.019) and Abbreviated Injury Scale head/neck score (5 [5-5] vs. 4 [3-4], p = 0.001) than survivors. The only radiologic measurement that differed between groups was greater soft tissue edema at mid C1 among patients who died (12.37 [7.60-14.95] vs. 7.86 [5.25-11.61], p = 0.013). Receiver operating characteristic curve analysis of soft tissue edema at mid C1 and mortality revealed 10.86 mm or greater of soft tissue width predicted mortality with sensitivity and specificity of 0.75. All other radiologic parameters, including the basion-dens interval, were comparable between groups (p > 0.05)., Conclusion: Among patients who arrive alive to hospital after traumatic CCD, greater radiologic dissociation is not associated with increased mortality. However, increased soft tissue edema at the level of mid C1, particularly 10.86 mm or greater, is associated with in-hospital death. These findings improve our understanding of this highly lethal injury and impart the ability to better prognosticate for patients arriving alive to hospital with CCD., Level of Evidence: Prognostic and Epidemiological, Level III.

Introduction: Prehospital vital signs are used to triage trauma patients to mobilize appropriate resources and personnel prior to patient arrival in the emergency department (ED). Due to inherent challenges in obtaining prehospital vital signs, concerns exist regarding their accuracy and ability to predict first ED vitals., Hypothesis/problem: The objective of this study was to determine the correlation between prehospital and initial ED vitals among patients meeting criteria for highest levels of trauma team activation (TTA). The hypothesis was that in a medical system with short transport times, prehospital and first ED vital signs would correlate well., Methods: Patients meeting criteria for highest levels of TTA at a Level I trauma center (2008-2018) were included. Those with absent or missing prehospital vital signs were excluded. Demographics, injury data, and prehospital and first ED vital signs were abstracted. Prehospital and initial ED vital signs were compared using Bland-Altman intraclass correlation coefficients (ICC) with good agreement as >0.60; fair as 0.40-0.60; and poor as <0.40)., Results: After exclusions, 15,320 patients were included. Mean age was 39 years (range 0-105) and 11,622 patients (76%) were male. Mechanism of injury was blunt in 79% (n = 12,041) and mortality was three percent (n = 513). Mean transport time was 21 minutes (range 0-1,439). Prehospital and first ED vital signs demonstrated good agreement for Glasgow Coma Scale (GCS) score (ICC 0.79; 95% CI, 0.77-0.79); fair agreement for heart rate (HR; ICC 0.59; 95% CI, 0.56-0.61) and systolic blood pressure (SBP; ICC 0.48; 95% CI, 0.46-0.49); and poor agreement for pulse pressure (PP; ICC 0.32; 95% CI, 0.30-0.33) and respiratory rate (RR; ICC 0.13; 95% CI, 0.11-0.15)., Conclusion: Despite challenges in prehospital assessments, field GCS, SBP, and HR correlate well with first ED vital signs. The data show that these prehospital measurements accurately predict initial ED vitals in an urban setting with short transport times. The generalizability of these data to settings with longer transport times is unknown.

The ACS Committee on Trauma specifies prehospital criteria that trigger trauma team activation (TTA). The study aims to define the relationship between TTA and time of day, mechanism of injury, and need for operative intervention. All trauma patients presenting to LAC+USC (January 2008-July 2018) after triggering TTA were screened. Patients were excluded if time of ED arrival was undocumented. Demographics, injury data, and outcomes were analyzed. After exclusions (<1%), 54,826 patients were enrolled. The median age was 35 [IQR 23-53]. The median Injury Severity Score was 4 [1-10]. The most common mechanisms of injury were falls (n = 14,166; 31%), auto versus pedestrian collisions (n = 11,921; 26%), and motor vehicle collisions (n = 11,024; 24%). Penetrating trauma comprised 16 per cent (n = 8,686). The busiest hour for TTAs was 19:00 to 20:00, although penetrating trauma was most common between 23:00 and 01:00. Emergent surgical intervention in absolute numbers was most frequent between 20:00 and 01:00. As a proportion of the number of TTAs per hour, emergent operative intervention was most frequent between 23:00 and 06:00. In conclusion, the volume of TTAs and the triggering mechanism of injury vary significantly by time of day. The need for operative intervention is highest overnight. This information can be used to help increase hospital preparedness and allocate resources accordingly.

Background: The distribution of trauma deaths was classically described as trimodal. With advances in both technology and trauma systems, this was reevaluated and found to be bimodal in the early 2000s. Over the last decade there have been continued improvements in trauma and intensive care unit (ICU) care, related to damage control techniques and evidence based ICU pathways. A better understanding of the distribution of trauma deaths may be used to improve trauma systems. This study aimed to evaluate the contemporary distribution of trauma deaths after the widespread implementation of modern trauma and critical care principles., Methods: This study included patients entered in the NTDB from 2008 to 2014. For dead patients, hospital length of stay was equated to time until death. Additional data was collected to include demographics, mechanism of injury, Injury Severity Score, and Abbreviated Injury Scale score. Histograms were plotted to demonstrate peaks in deaths. Survival analysis was performed with Kaplan-Meier curves and Gehan-Breslow generalized Wilcoxon tests., Results: 4,185,009 patients were analyzed. Thirty-four percent of all deaths occurred within the first 24 hours of admission. The factors most associated with death in the first 24 hours were severe abdominal trauma (73%), penetrating trauma (55%), and severe extremity trauma (58%). Among patients with penetrating trauma and an abdominal Abbreviated Injury Scale score of 4 or higher, 83% of deaths occurred within 24 hours. When plotted, the distribution of deaths was seen to fall rapidly after the first 24 hours and continued to be flat for 30 days in all subgroups analyzed., Conclusion: In this study, the distribution of trauma deaths no longer appears to be trimodal. This may reflect advances in trauma and ICU care, and the widespread adaption of damage control principles. Early deaths, however, remains a significant challenge, specifically from non-compressible abdominal hemorrhage and extremity trauma. Primary prevention and early hemorrhage control must continue to be a focus of research and trauma systems., Level of Evidence: Epidemiologic, level IV.
