BACKGROUND/UNASSIGNED:Intimate partner violence (IPV) is a serious public health issue with a substantial burden on society. Screening and intervention practices vary widely and there are no standard guidelines. Our objective was to review research on current practices for IPV prevention in emergency departments and trauma centers in the USA and provide evidenced-based recommendations. METHODS/UNASSIGNED:An evidence-based systematic review of the literature was conducted to address screening and intervention for IPV in adult trauma and emergency department patients. The Grading of Recommendations, Assessment, Development and Evaluations methodology was used to determine the quality of evidence. Studies were included if they addressed our prespecified population, intervention, control, and outcomes questions. Case reports, editorials, and abstracts were excluded from review. RESULTS/UNASSIGNED:Seven studies met inclusion criteria. All seven were centered around screening for IPV; none addressed interventions when abuse was identified. Screening instruments varied across studies. Although it is unclear if one tool is more accurate than others, significantly more victims were identified when screening protocols were implemented compared with non-standardized approaches to identifying IPV victims. CONCLUSION/UNASSIGNED:Overall, there were very limited data addressing the topic of IPV screening and intervention in emergency medical settings, and the quality of the evidence was low. With likely low risk and a significant potential benefit, we conditionally recommend implementation of a screening protocol to identify victims of IPV in adults treated in the emergency department and trauma centers. Although the purpose of screening would ultimately be to provide resources for victims, no studies that assessed distinct interventions met our inclusion criteria. Therefore, we cannot make specific recommendations related to IPV interventions. PROSPERO REGISTRATION NUMBER/UNASSIGNED:CRD42020219517.

INTRODUCTION: Coronavirus disease 2019 (COVID19) is known to cause coagulopathy as multiple systemic coagulation and inflammatory responses are activated during infectious complications. In COVID19 patients, hypercoagulopathy usually presents with an elevated D-dimer level.
METHOD(S): All patients >= 18 years old who were admitted to NYU Langone Hospital-Long Island with a primary diagnosis of COVID-19 or with a flagged admission of COVID19 during April 1, 2020 to June 30, 2020 were included. IRB approval was acquired prior to data collection and upon permission, the clinical pharmacy IT department ran a report to identify patients. Most patients had a positive reverse-transcription polymerase chain reaction (RT-PCR) test during their admission, while a small number of patients were diagnosed before admission. Admissions included ICU patients or general ward patients. Series of D dimers were recorded.
RESULT(S): There were 350 patients enrolled in the study, 331 had no VTE, 19 had VTE. Peak D dimer was 4876 (range 1509 to 15,872) in VTE group vs. 680 in non VTE group (range: 257 to 2723). 47.4% of VTE group had peak D dimer greater than 5000 vs. 16% of non VTE group. Surprisingly, there was no difference in mortality between the two groups: 26.3% for VTE group; 19.9% in non VTE group, (p=0.556). However, VTE group had higher ICU admission rate 42.1% vs. 20.2% of non VTE group, p=0.039. Length of intubation was also significantly higher in VTE group (27 days) comparing to non VTE group (6 days), p=0.007.
CONCLUSION(S): Covid 19 patients with VTE have much higher D dimer than non VTE Covid 19 patients. Although there is no difference in mortality in the two groups in our study, VTE group is associated with higher ICU admission as well as longer length of intubation days

INTRODUCTION/BACKGROUND:Coronavirus disease 2019 (COVID-19) has been shown to affect outcomes among surgical patients. We hypothesized that COVID-19 would be linked to higher mortality and longer length of stay of trauma patients regardless of the injury severity score (ISS). METHODS:We performed a retrospective analysis of trauma registries from two level 1 trauma centers (suburban and urban) from March 1, 2019, to June 30, 2019, and March 1, 2020, to June 30, 2020, comparing baseline characteristics and cumulative adverse events. Data collected included ISS, demographics, and comorbidities. The primary outcome was time from hospitalization to in-hospital death. Outcomes during the height of the first New York COVID-19 wave were also compared with the same time frame in the prior year. Kaplan-Meier method with log-rank test and Cox proportional hazard models were used to compare outcomes. RESULTS:There were 1180 trauma patients admitted during the study period from March 2020 to June 2020. Of these, 596 were never tested for COVID-19 and were excluded from the analysis. A total of 148 COVID+ patients and 436 COVID- patients composed the 2020 cohort for analysis. Compared with the 2019 cohort, the 2020 cohort was older with more associated comorbidities, more adverse events, but lower ISS. Higher rates of historical hypertension, diabetes, neurologic events, and coagulopathy were found among COVID+ patients compared with COVID- patients. D-dimer and ferritin were unreliable indicators of COVID-19 severity; however, C-reactive protein levels were higher in COVID+ relative to COVID- patients. Patients who were COVID+ had a lower median ISS compared with COVID- patients, and COVID+ patients had higher rates of mortality and longer length of stay. CONCLUSIONS:COVID+ trauma patients admitted to our two level 1 trauma centers had increased morbidity and mortality compared with admitted COVID- trauma patients despite age and lower ISS. C-reactive protein may play a role in monitoring COVID-19 activity in trauma patients. A better understanding of the physiological impact of COVID-19 on injured patients warrants further investigation.

INTRODUCTION/BACKGROUND:Stop the Bleed (STB) is a national training program aiming to decrease the mortality associated with life-threatening bleeding due to injury. The purpose of this study was to evaluate the efficacy and confidence level of security personnel placing a tourniquet (TQ) compared to civilians. METHODS:Pre and post questionnaires were shared with security personnel (Group 1) and civilians (Group 2). Both groups were assessed to determine comfort level with TQ placement. Time and success rate for placement was recorded pre- and post-STB training. A generalized linear mixed model or generalized estimating equations was used to compare pre and post measurements. RESULTS:There were 234 subjects enrolled. There was a statistically significant improvement between the pre- and post-training responses in both groups with respect to comfort level in placing a TQ. Participants also demonstrated increased familiarity with the anatomy and bleeding control after STB training. A higher successful TQ placement was obtained in both groups after STB training (Pre-training: Group 1 [17.4%], Group 2 [12.8%]; Post-training: Group 1 [94.8%], Group 2 [92.3%]). Both groups demonstrated improved time to TA placement with a longer mean time improvement achieved in Group 1. Although the time to TQ placement pre-and post-training was statistically significant, we found that the post-training times between Groups 1 and 2 were similar (P = .983). CONCLUSIONS:Participants improved their confidence level with the use of hemorrhage control techniques and dramatically increased the rate and time to successful placement of a TQ. While civilians had the greatest increase in comfort level, the security personnel group saw the most significant reduction in the time to successful TQ placement. These findings highlight the critical role of STB in educating and empowering both civilians and security personnel in bleeding control techniques.

BACKGROUND:We hypothesized that the outcomes of trauma patients with a body mass index (BMI) equal to or greater than 30 compared to patients with BMI less than 30 would not differ at a level 1 trauma center that is also a Metabolic and Bariatric Surgery Center of Excellence in the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP). STUDY DESIGN/METHODS:Patients equal to and greater than 18 years old treated between 1/1/2018 and 12/31/2020 were included. Demographics, BMI, comorbidities, and outcomes (hospital-LOS, ICU-LOS, blood products used, and mortality) were compared between 2 groups: obese (BMI ≥30) vs non-obese (BMI <30). RESULTS:< .0001). When adjusted for age, sex, DM, dementia, ISS, and ICU admission, there was no statistically significant difference in hospital-LOS (4.30 [95% CI: 4.10, 4.52] vs 4.48 [95% CI: 4.18, 4.79]) or mortality. No statistical differences were seen between the 2 groups in blood product use. CONCLUSIONS:Obesity did not correlate with poorer outcomes at an ACS-verified level 1 Trauma Center and Bariatric Surgery Center of Excellence. Further studies are needed to determine whether outcomes vary at hospitals without both designations.

BACKGROUND:Data access through smartphone applications (apps) has reframed procedure and policy in healthcare, but its impact in trauma remains unclear. Citizen is a free app that provides real-time alerts curated from 911 dispatch data. Our primary objective was to determine whether app alerts occurred earlier than recorded times for trauma team activation and emergency department arrival. METHODS:Trauma registry entries were extracted from a level one urban trauma center from January 1, 2018 to June 30, 2019 and compared with app metadata from the center catchment area. We matched entries to metadata according to description, date, time, and location then compared metadata timestamps to trauma team activation and emergency department arrival times. We computed percentage of time the app reported traumatic events earlier than trauma team activation or emergency department arrival along with exact binomial 95% confidence interval; median differences between times were presented along with interquartile ranges. RESULTS:Of 3,684 trauma registry entries, 209 (5.7%) matched app metadata. App alerts were earlier for 96.1% and 96.2% of trauma team activation and emergency department arrival times, respectively, with events reported median 36 (24-53, IQR) minutes earlier than trauma team activation and 32 (25-42, IQR) minutes earlier than emergency department arrival. Registry entries for younger males, motor vehicle-related injuries and penetrating traumas were more likely to match alerts (P < .0001). CONCLUSION/CONCLUSIONS:Apps like Citizen may provide earlier notification of traumatic events and therefore earlier mobilization of trauma service resources. Earlier notification may translate into improved patient outcomes. Additional studies into the benefit of apps for trauma care are warranted.

PURPOSE: Conclusive data on safety of remdesivir in renal impaired as well as the incidence of liver injury are lacking. The primary objective of this study is to assess the incidence of acute kidney injury (AKI) and to trend the liver function tests (LFTs) during remdesivir treatment and change in eGFR from baseline to end of remdesivir treatment as well as 48 hours after completion of therapy.
METHOD(S): This is a retrospective chart review study including adult Covid19 patients receiving remdesivir with a baseline eGFR< 30 ml/min per 1.73 m^2 from December 2020 to May 2021. The primary outcome of the study is the incidence of AKI and hepatic injury. The secondary outcome is to assess the efficacy of remdesivir defined by oxygen requirement during therapy.
RESULT(S): Seventy-one patients were included in the study. Average eGFR improved by 30.3% at the immediate end of remdesivir treatment and by 30.6% at 48 hours after the end of the treatment (both P< 0.0001). Comparing to baseline, creatinine at the end of remdesivir treatment decreased by 20.9% (P< 0.0001), creatinine of 48 hour after remdesivir treatment decreased by 20.5% (P< 0.0001). Creatinine clearance increased by 26.6% (P< 0.0001) at end of treatment and increased by 26.2% (P< 0.0001) by 48 hours after end of treatment. AST average increased by 2.5% at the end of remdesivir treatment (P=0.727). At 48 hours after remdesivir completion, average AST dropped by 15.8% (P=0.021). ALT average increased by 25% (P=0.004) at the end of remdesivir treatment and increased by 12.0% (P=0.137) at 48 hours after remdesivir completion. Both direct and total bilirubin at end of remdesivir treatment as well as 48 hours later remained stable and did not have significant changes from baseline (P >0.05). Overall, 38% (27 out of 71 patients) experienced oxygenation improvement shown by down-titration of oxygen therapy. Fifty-seven percent of patients received other nephrotoxic medications. The mortality rate is 33.8%. Fifteen of the 71 patients were admitted into ICU. Sixty-five percent (46/71) patients were discharged alive from hospital.
CONCLUSION(S): This study showed that remdesivir use in renally impaired Covid 19 patients with eGFR< 30 ml/min is safe and effective. However, large and prospective studies are needed to validate our findings

PURPOSE/OBJECTIVE:Safety of remdesivir in patients with renal impairment is unknown. Incidence of liver injury secondary to remdesivir is also unknown. The objective of this study is to assess the incidence of acute kidney injury (AKI) and to trend the liver enzymes during remdesivir treatment and change in eGFR from baseline to end of treatment as well as 48 h post completion of remdesivir therapy. METHODS:This is a retrospective chart review study including adult patients admitted with COVID-19 receiving remdesivir with a baseline eGFR < 30 ml/min per 1.73 m^2 from December 2020 to May 2021. The primary outcome was to assess the incidence of AKI and hepatic injury. The secondary outcome was to assess the efficacy of remdesivir defined by change in oxygen requirement. RESULTS:Seventy-one patients were included in the study. Patients experienced an improvement in eGFR from baseline (T0) to end of remdesivir treatment (T1), as well as 48 h after the end of the treatment (T2) ( + 30.3% and + 30.6% respectively, P < .0001). Creatinine reduced from baseline (T0) to T1 and T2 (-20.9% and -20.5% respectively, P < .0001). Creatinine clearance improved from baseline to T1 and T2 ( + 26.6% and + 26.2% respectively, p < .0001). Elevation of aminotransferase (AST) was observed at T1 ( + 2.5%, P  =  .727), however, AST reduction was seen at T2 (-15.8%, P  =  .021). Elevation in alanine transaminase (ALT) was observed at T1 and T2 ( + 25% and + 12%, P  =  .004 and P  =  .137 respectively). Both direct and total bilirubin remained stable and were not significantly changed from baseline. CONCLUSION/CONCLUSIONS:Our study showed that remdesivir use in renally-impaired patients with eGFR < 30 ml/min is safe. Remdesivir may be considered as a therapeutic option in this population with COVID-19 infection.

Introduction: Stop the Bleed (STB) is a national training program aiming to decrease the mortality associated with life-threatening bleeding due to injury. The purpose of this study was to evaluate the efficacy and confidence level of security personnel placing a tourniquet (TQ) compared to civilians.
Method(s): Pre and post questionnaires were shared with security personnel (Group 1), and civilians (Group 2). Both groups were assessed to determine comfort level with TQ placement. Time and success rate for placement was recorded pre- and post-STB training. A generalized linear mixed model or generalized estimating equations were used.
Result(s): 234 subjects were enrolled. There was a statistically significant improvement between the pre- and post-training responses in both groups with respect to comfort level in TQ placing. Participants also demonstrated increased familiarity with the anatomy and bleeding control after being trained. A higher successful tourniquet placement was obtained in both groups after training (Pre-training: Group-1[17.4%], Group-2[12.8%], Post-training: Group-1[94.8%], Group-2[92.3%]). Both groups demonstrated improved time to placement with a longer mean time improvement achieved in Group 1. Although the time to TQ placement pre-and post-training was statistically significant, we found that the post-training times between groups 1 and 2 were similar (p=0.983).
Conclusion(s): Participants improved their confidence level and dramatically increased the rate and time to successful TQ placement. While civilians had the greatest increase in comfort level, the security personnel group saw the most significant reduction in the time to successful placement. These findings highlight the critical role of STB in bleeding control techniques.
