- BACKGROUND: Blood-based balanced resuscitation is a standard of care in massively bleeding trauma patients. No data exists as to when this therapy no longer significantly affects mortality. We sought to determine if there is a threshold beyond which further massive transfusion will not affect in-hospital mortality.METHODS: The Trauma Quality Improvement database was queried for all adult patients registered between 2013 and 2017 who received at least one unit of blood (PRBC) within 4 hours of arrival. In-hospital mortality was evaluated based on the total transfusion volume (TTV) at 4 and 24 hours in the overall cohort (OC) and in a balanced transfusion cohort (BC), composed of patients who received transfusion at a ratio of 1:1-2:1 PRBC-to-plasma. A bootstrapping method in combination with multivariable Poisson regression (MVR) was used to find a cutoff after which additional transfusion no longer affected in-hospital mortality. MVR was used to control for age, sex, race, highest abbreviated injury score in each body region, comorbidities, advanced directives limiting care, and the primary surgery performed for hemorrhage control.RESULTS: The OC consisted of 99,042 patients of which 28,891 and 30,768 received a balanced transfusion during the first 4 and 24 hours, respectively. The mortality rate plateaued after a TTV of 40.5 units (95% CI, 40-41) in the OC at 4 hours and after a TTV of 52.8 units (95% CI, 52-53) at 24 hours following admission. In the BC, mortality plateaued at a TTV of 39 units (95% CI, 39-39) and 53 units (95% CI, 53-53) at 4- and 24-hours following admission, respectively.CONCLUSION: Transfusion thresholds exist beyond which ongoing transfusion is not associated with any clinically significant change in mortality. These TTVs can be used as markers for resuscitation timeouts in order to assess the plan of care moving forward.LEVEL OF EVIDENCE: Level V, prognostic and epidemiological.

- INTRODUCTION: Early tracheostomy (ET) is associated with a lower incidence of pneumonia (PNA) and mechanical ventilation duration (MVD) in hospitalized patients with trauma. The purpose of this study is to determine if ET also benefits older adults compared to the younger cohort.METHODS: Adult hospitalized trauma patients who received a tracheostomy as registered in The American College of Surgeons Trauma Quality Improvement Program from 2013 to 2019 were analyzed. Patients with tracheostomy prior to admission were excluded. Patients were stratified into 2 cohorts consisting of those aged ≥65 and those aged <65. These cohorts were analyzed separately to compare the outcomes of ET (<5 d; ET) versus late tracheostomy (LT) (≥5 d; LT). The primary outcome was MVD. Secondary outcomes were in-hospital mortality, hospital length of stay (HLOS), and PNA. Univariate and multivariate analyses were performed with significance defined as P value < 0.05.RESULTS: In patients aged <65, ET was performed within a median of 2.3 d (interquartile range, 0.47-3.8) after intubation and a median of 9.9 d (interquartile range, 7.5-13) in the LT group. The ET group's Injury Severity Score was significantly lower with fewer comorbidities. There were no differences in injury severity or comorbidities when comparing the groups. ET was associated with lower MVD (d), PNA, and HLOS on univariate and multivariate analyses in both age cohorts, although the degree of benefit was higher in the less than 65 y cohort [ET versus LT MVD: 5.08 (4.78-5.37), P < 0.001; PNA: 1.45 (1.36-1.54), P < 0.001; HLOS: 5.48 (4.93-6.04), P < 0.001]. Mortality did not differ based on time to tracheostomy.CONCLUSIONS: ET is associated with lower MVD, PNA, and HLOS in hospitalized patients with trauma regardless of age. Age should not factor into timing for tracheostomy placement.

- BACKGROUND: Race is associated with differences in quality of care process measures and incidence of venous thromboembolism (VTE) in trauma patients. We aimed to investigate if racial disparities exist in the administration of VTE prophylaxis in trauma patients.METHODS: We queried the Trauma Quality Improvement Project database from 2017 to 2019. Patients ages ≥16 years old with ISS ≥15 were included. Patients with no signs of life on arrival, any AIS ≥6, hospital length of stay <1 day, anticoagulant use before admission, or without recorded race were excluded. Patients were grouped by race: white, black, Asian, American Indian, and Native Hawaiian or Pacific Islander. The association between VTE prophylaxis administration and race was determined using a Poisson regression model with robust standard errors to adjust for confounders.RESULTS: A total of 285,341 patients were included. Black patients had the highest rates of VTE prophylaxis exposure (73.8%), shortest time to administration (1.6 days), and highest use of low molecular weight heparin (56%). Black patients also had the highest incidence of deep vein thrombosis (2.8%) and pulmonary embolism (1.4%). Black patients were 4% more likely to receive VTE prophylaxis than white patients [adj. IRR (95% CI): 1.04 (1.03-1.05), P < .001]. American Indians were 8% less likely to receive VTE prophylaxis [adj. IRR (95% CI): .92 (.88-.97), P < .001] than white patients. No differences between white and Asian or Native Hawaiian or Pacific Islander patients existed.DISCUSSION: While black patients had the highest incidence of DVT and PE, they had higher administration rates and earlier initiation of VTE prophylaxis. Further work can elucidate modifiable causes of these differences.

- BACKGROUND: The Brain Trauma Foundation recommends intracranial pressure (ICP) monitoring in patients with severe traumatic brain injury (TBI). Race is associated with worse outcomes after TBI. The reasons for racial disparities in clinical decision-making around ICP monitor placement remain unclear.STUDY DESIGN: We queried the TQIP database from 2017 to 2019 and included patients 16 years or older, with blunt severe TBI, defined as a head abbreviated injury score 3 or greater. Exclusion criteria were missing race, those without signs of life on admission, length of stay 1 day or less, and AIS of 6 in any body region. The primary outcome was ICP monitor placement, which was calculated using a Poisson regression model with robust SEs while adjusting for confounders.RESULTS: A total of 260,814 patients were included: 218,939 White, 29,873 Black, 8,322 Asian, 2,884 American Indian, and 796 Native Hawaiian or Other Pacific Islander. Asian and American Indian patients had the highest rates of midline shift (16.5% and 16.9%). Native Hawaiian or Other Pacific Islanders had the highest rates of neurosurgical intervention (19.3%) and ICP monitor placement (6.5%). Asian patients were found to be 19% more likely to receive ICP monitoring (adjusted incident rate ratio 1.19; 95% CI 1.06 to 1.33; p = 0.003], and American Indian patients were 38% less likely (adjusted incident rate ratio 0.62; 95% CI 0.49 to 0.79; p < 0.001), compared with White patients, respectively. No differences were detected between White and Black patients.CONCLUSIONS: ICP monitoring use differs by race. Further work is needed to elucidate modifiable causes of this difference in the management of severe TBI.

- BACKGROUND: Existing study findings on firearms-related injury patterns are largely skewed towards males, who comprise the majority of this injury population. Given the paucity of existing data for females with these injuries, we aimed to elucidate the demographics, injury patterns, and outcomes of firearms-related injury in females compared with males in the USA.MATERIALS AND METHODS: A 7-year (2013-2019) retrospective review of the National Trauma Database was conducted to identify all adult patients who suffered firearms-related injuries. Patients who were males were matched (1:1, caliper 0.2) to patients who were females by demographics, comorbidities, injury patterns and severity, and payment method, to compare differences in mortality and several other post-injury outcomes.RESULTS: There were 196 696 patients admitted after firearms-related injury during the study period. Of these patients, 23 379 (11.9%) were females, 23 378 of whom were successfully matched to a male counterpart. After matching, females had a lower rate of in-hospital mortality (18.6% vs. 20.0%, p<0.001), deep vein thrombosis (1.2% vs. 1.5%, p=0.014), and had a lower incidence of drug or alcohol withdrawal syndrome (0.2% vs. 0.5%, p<0.001) compared with males.CONCLUSION: Female victims of firearms-related injuries experience lower rates of mortality and complications compared with males. Further studies are needed to elucidate the cause of these differences.LEVEL OF EVIDENCE: Level III.

- Objective: Nearly 7% of the adult US population has symptomatic Attention Deficit Hyperactivity Disorder (ADHD), which is associated with an increased risk for traumatic injury. There is limited data on the outcome of hospitalized trauma patients with ADHD. This study aimed to use a large nationwide database to investigate the relationship between a diagnosis of ADHD and clinical outcomes in hospitalized patients after major trauma.Methods: All patients 18 years or older in the National Trauma Database were retrospectively reviewed. Propensity score analysis was used to match patients with and without the diagnosis of ADHD at a 1:1 ratio based on age, sex, race, highest AIS in each region, comorbidities, and the presence of advanced directives limiting care. Outcomes of patients with ADHD admitted to the trauma service between the years 2015 and 2017 were compared to those without ADHD. The primary outcome of interest was in-hospital mortality, while the secondary outcomes included complications and hospital length of stay.Results: There were 9399 patients included in the study with a diagnosis of ADHD. These patients were overall more likely to be younger, male, and Caucasian, compared to their matched counterparts without ADHD. ADHD was associated with a significantly lower in-hospital mortality than patients without ADHD. There was no difference in the ICU admission rate, ICU LOS, ventilator use, or complication rates between patients with and without ADHD.Conclusion: A diagnosis of ADHD has a complex association with clinical outcomes after trauma. The current large national analysis found that patients with a diagnosis of ADHD had significantly lower overall in-hospital mortality.
