Early VTE prophylaxis in severe traumatic brain injury: A propensity score weighted EAST multicenter study.

BACKGROUND: Patients with traumatic brain injury (TBI) are at high risk of venous thromboembolism events (VTE). We hypothesized that early chemical VTE prophylaxis initiation (≤24 hours of a stable head CT) in severe TBI would reduce VTE without increasing risk of intracranial hemorrhage expansion (ICHE). METHODS: A retrospective review of adult patients 18 years or older with isolated severe TBI (Abbreviated Injury Scale score, ≥ 3) who were admitted to 24 Level I and Level II trauma centers from January 1, 2014 to December 31 2020 was conducted. Patients were divided into those who did not receive any VTE prophylaxis (NO VTEP), who received VTE prophylaxis ≤24 hours after stable head CT (VTEP ≤24) and who received VTE prophylaxis >24 hours after stable head CT (VTEP>24). Primary outcomes were VTE and ICHE. Covariate balancing propensity score weighting was utilized to balance demographic and clinical characteristics across three groups. Weighted univariate logistic regression models were estimated for VTE and ICHE with patient group as predictor of interest. RESULTS: Of 3,936 patients, 1,784 met inclusion criteria. Incidences of VTE was significantly higher in the VTEP>24 group, with higher incidences of DVT in the group. Higher incidences of ICHE were observed in the VTEP≤24 and VTEP>24 groups. After propensity score weighting, there was a higher risk of VTE in patients in VTEP >24 compared with those in VTEP≤24 (odds ratio, 1.51; 95% confidence interval, 0.69-3.30; p = 0.307), however was not significant. Although, the No VTEP group had decreased odds of having ICHE compared with VTEP≤24 (odds ratio, 0.75; 95% confidence interval, 0.55-1.02, p = 0.070), the result was not statistically significant. CONCLUSION: In this large multi-center analysis, there were no significant differences in VTE based on timing of initiation of VTE prophylaxis. Patients who never received VTE prophylaxis had decreased odds of ICHE. Further evaluation of VTE prophylaxis in larger randomized studies will be necessary for definitive conclusions.

Social Determinants of Health in Trauma.

Social determinants (SD) refer to a variety of environmental factors that can influence certain clinical outcomes. SD that affect clinical outcomes in trauma patients are largely understudied. We hypothesized that patients with an "at risk" (AR) classification for any SD will have a greater frequency of negative outcomes when compared to their "not at risk" (NAR) counterparts. A retrospective review was performed (1/2021-2/2022) of all trauma patients that met the inclusion criteria. 2225 patients were included. SD included (based on collection rates) for analysis were: tobacco use, stress, and intimate partner violence. Tobacco usage was the only SD that was significantly associated with a higher 30-day mortality. This study demonstrated a paucity of data in the medical record regarding SD. In an effort to provide more inclusive care and address health disparities in our patient population, there is a need for more complete data collection upon admission/duration of hospital stay.

Use of Cold-Stored Whole Blood is Associated With Improved Mortality in Hemostatic Resuscitation of Major Bleeding: A Multicenter Study.

OBJECTIVE: The aim of this study was to identify a mortality benefit with the use of whole blood (WB) as part of the resuscitation of bleeding trauma patients. BACKGROUND: Blood component therapy (BCT) is the current standard for resuscitating trauma patients, with WB emerging as the blood product of choice. We hypothesized that the use of WB versus BCT alone would result in decreased mortality. METHODS: We performed a 14-center, prospective observational study of trauma patients who received WB versus BCT during their resuscitation. We applied a generalized linear mixed-effects model with a random effect and controlled for age, sex, mechanism of injury (MOI), and injury severity score. All patients who received blood as part of their initial resuscitation were included. Primary outcome was mortality and secondary outcomes included acute kidney injury, deep vein thrombosis/pulmonary embolism, pulmonary complications, and bleeding complications. RESULTS: A total of 1623 [WB: 1180 (74%), BCT: 443(27%)] patients who sustained penetrating (53%) or blunt (47%) injury were included. Patients who received WB had a higher shock index (0.98 vs 0.83), more comorbidities, and more blunt MOI (all P <0.05). After controlling for center, age, sex, MOI, and injury severity score, we found no differences in the rates of acute kidney injury, deep vein thrombosis/pulmonary embolism or pulmonary complications. WB patients were 9% less likely to experience bleeding complications and were 48% less likely to die than BCT patients ( P <0.0001). CONCLUSIONS: Compared with BCT, the use of WB was associated with a 48% reduction in mortality in trauma patients. Our study supports the use of WB use in the resuscitation of trauma patients.

A Statewide Analysis of Pediatric Liver Injuries Treated at Adult Versus Pediatric Trauma Centers.

INTRODUCTION: Hemodynamically normal pediatric trauma patients with solid organ injury receive nonoperative management. Prior research supports that pediatric patients have higher rates of nonoperative management at pediatric trauma centers (PTCs). We sought to evaluate differences in outcomes of pediatric trauma patients with liver injuries. We hypothesized that the type of trauma center (PTC versus adult trauma center [ATC]) would not be associated with any difference in mortality. METHODS: The Pennsylvania Trauma Outcome Study database was retrospectively queried from 2003 to 2018 for all patients (<15 y) with liver injuries by International Classification of Disease 9 and 10 codes. Patients were categorized based on admission to the PTC or ATC. The primary endpoint was mortality with secondary endpoints being operative intervention and length of stay. Multivariate logistic regressions assessed the adjusted impact on mortality and surgical intervention. RESULTS: Of the 1600 patients with liver trauma, 607 met inclusion criteria. A total of 78.4% were treated at PTCs. Patients underwent hepatobiliary surgery more frequently at ATCs (11.5% [n = 15] versus 2.74% [n = 13], P < 0.001). Adjusted analysis showed lower odds of surgical intervention for hepatobiliary injuries at PTCs (adjusted odds ratio: 0.17, P = 0.001). There was a decrease in mortality at PTCs versus ATCs (adjusted odds ratio: 0.38, P = 0.032). CONCLUSIONS: Our statewide analysis showed that pediatric trauma patients with liver injuries treated at ATCs were associated with having higher odds of mortality and higher incidence of operative management for hepatobiliary injuries than those treated at PTCs. In addition, between centers, patients had similar functional status at discharge.

An Evaluation of Pediatric Secondary Overtriage in the Pennsylvania Trauma System.

BACKGROUND: We sought to determine the secondary overtriage rate of pediatric trauma patients admitted to pediatric trauma centers. We hypothesized that pediatric secondary overtriage (POT) would constitute a large percentage of admissions to PTC. MATERIALS AND METHODS: The Pennsylvania Trauma Outcome Study database was retrospectively queried from 2003 to 2017 for pediatric (age ≤ 18 y) trauma patients transferred to accredited pediatric trauma centers in Pennsylvania (n = 6). Patients were stratified based on discharge within (early) and beyond (late) 24 h following admission. POT was defined as patients transferred to a PTC with an early discharge. Multilevel mixed-effects logistic regression model controlling for demographic and injury severity covariates were utilized to determine the adjusted impact of injury patterns on early discharge. RESULTS: A total of 37,653 patients met inclusion criteria. For transfers, POT compromised 18,752 (49.8%) patients. Compared to POT, non-POT were more severely injured (ISS: 10 versus 6;P < 0.001) and spent less time in the ED (Min: 181 versus 207;P < 0.001). In adjusted analysis, concussion, closed skull vault fractures, supracondylar humerus fractures, and consults to neurosurgery were associated with increased odds of POT. Overall, femur fracture, child abuse evaluation, and consults to plastic surgery, orthopedics, and ophthalmology were all associated with a decreased risk of being POT. CONCLUSIONS: POT comprises 49.8% of PTC transfer admissions in Pennsylvania's trauma system. Improving community resources for management of pediatric concussion and mild TBI could result in decreased rates of POT to PTCs. Developing better inter-facility transfer guidelines and increased education of adult TC and nontrauma center hospitals is needed to decrease POT. LEVEL OF EVIDENCE: Epidemiologic study, level III.
