Background Hemorrhage remains a major cause of death around the world. Eighty percent of trauma patients in India do not receive medical care within the first hour. The etiology of these poor outcomes is multifactorial. We describe findings from the first Stop the Bleed (StB) course recently offered to a group of medical providers in southern India. Methods A cross-sectional survey of 101 participants who attended StB trainings in India was performed. Pre-training and post-training questionnaires were collected from each participant. In total, 88 healthcare providers’ responses were analyzed. Three bleeding control skills were presented: wound compression, wound packing, and tourniquet application. Results Among participants, only 23.9% had received prior bleeding control training. Participants who reported feeling ‘extremely confident’ responding to an emergency medical situation rose from 68.2% prior to StB training to 94.3% post-training. Regarding hemorrhage control abilities, 37.5% felt extremely confident before the training, compared with 95.5% after the training. For wound packing and tourniquet application, 44.3% and 53.4%, respectively, felt extremely confident pre-training, followed by 97.7% for both skills post-training. Importantly, 90.9% of StB trainees felt comfortable teaching newly acquired hemorrhage control skills. A significant majority of participants said that confidence in their wound packing and tourniquet skills would improve with more realistic mannequins. Conclusion To our knowledge, this is the first StB training in India. Disparities in access to care, long transport times, and insufficient numbers of prehospital personnel contribute to its significant trauma burden. Dissemination of these critical life-saving skills into this region and the resulting civilian interventions will increase the number of trauma patients who survive long enough to reach a trauma center. Additionally, considerations should be given to translating the course into local languages to increase program reach. Level of Evidence Level IV.

BACKGROUND: Road traffic crashes (RTCs) are a global health burden, particularly in India, where response times for first responders can be prolonged. Prior to enactment of a Good Samaritan Law (GSL) in 2016, involved bystanders could face criminal and financial liability for assisting at an RTC site. This study evaluates the impact of GSL on bystander RTC attitudes, awareness, and experiences in India, comparing outcomes pre- and post-GSL implementation across metropolitan cities (MCs) and nonmetropolitan cities (NMCs). We hypothesized that GSL would lead to increased bystander willingness to assist the RTC victim. METHODS: This retrospective, cross-sectional, observational study analyzed data from two national surveys conducted in 2013 (pre-GSL, n = 1,027) and 2018 (post-GSL, n = 3,667) across 7 and 11 Indian cities, respectively. Difference-in-difference analysis, propensity score matching, and regression models were used to assess changes in willingness to assist RTC victims, awareness of GSL, legal and financial fears, and awareness of GSL. RESULTS: Post-GSL implementation saw an increase in willingness to assist RTC victims (Δ = +65.4%, p < 0.001) and substantial decreases in fear regarding legal (Δ = −81%, p < 0.001) and financial consequences (Δ = −75.8%, p < 0.001) of rendering assistance. GSL awareness was higher in NMCs (n = 2,215, 31.2%) compared with MCs (n = 838, 9.25%) among general citizens (p < 0.001). Males showed higher willingness to assist RTC victims (p < 0.01), whereas individuals with postgraduate education demonstrated increased awareness of GSL (p < 0.01). CONCLUSION: The implementation of GSL in India has transformed bystander intervention in RTCs, increasing the reported likelihood of assistance and substantially reducing legal and financial concerns. This shift demonstrates GSL's potential to improve outcomes for RTC victims. However, disparities in awareness between MCs and NMCs, as well as sex- and education-based differences, highlight the need for targeted educational campaigns. Future initiatives should focus on improving application of the law and strengthening the entire trauma chain of survival. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Introduction: The utility of pancreaticoduodenectomy (PD) for high-grade traumatic injuries remains unclear and data surrounding its use are limited. We hypothesized that PD does not result in improved outcomes when compared with non-PD surgical management of grade IV–V pancreaticoduodenal injuries. Methods: This is a retrospective, multicenter analysis from 35 level 1 trauma centers from January 2010 to December 2020. Included patients were ≥15 years of age with the American Association for the Surgery of Trauma grade IV–V duodenal and/or pancreatic injuries. The study compared operative repair strategy: PD versus non-PD. Results: The sample (n=95) was young (26 years), male (82%), with predominantly penetrating injuries (76%). There was no difference in demographics, hemodynamics, or blood product requirement on presentation between PD (n=32) vs non-PD (n=63). Anatomically, PD patients had more grade V duodenal, grade V pancreatic, ampullary, and pancreatic ductal injuries compared with non-PD patients (all p<0.05). 43% of all grade V duodenal injuries and 40% of all grade V pancreatic injuries were still managed with non-PD. One-third of non-PD duodenal injuries were managed with primary repair alone. PD patients had more gastrointestinal (GI)-related complications, longer intensive care unit length of stay (LOS), and longer hospital LOS compared with non-PD (all p<0.05). There was no difference in mortality or readmission. Multivariable logistic regression analysis determined PD to be associated with a 3.8-fold greater odds of GI complication (p=0.010) compared with non-PD. In a subanalysis of patients without ampullary injuries (n=60), PD patients had more anastomotic leaks compared with the non-PD group (3 (30%) vs 2 (4%), p=0.028). Conclusion: While PD patients did not have worse hemodynamics or blood product requirements on admission, they sustained more complex anatomic injuries and had more GI complications and longer LOS than non-PD patients. We suggest that the role of PD should be limited to cases of massive destruction of the pancreatic head and ampullary complex, given the likely procedure-related morbidity and adverse outcomes when compared with non-PD management. Level of evidence: IV, Multicenter retrospective comparative study.

Introduction: Screening, brief intervention, and referral to treatment (SBIRT) has demonstrated up to 50% reduction in alcohol-related traumatic injury and is mandated by the American College of Surgeons for trauma center accreditation. While SBIRT effectiveness has been previously investigated, optimal implementation in the trauma setting has not. We sought to improve SBIRT compliance through integration of screening into a performance improvement checklist (PIC) deployed during morning report. We hypothesized that PIC would establish a self-sustaining model for improved alcohol screening/intervention. Methods: This was a retrospective study comparing trauma patients pre-PIC (January–May 2022) to post-PIC (January–May 2023) after PIC implementation in January 2023. The primary outcome was SBIRT performance. The PIC prompted alcohol intervention specialist consultation if blood alcohol content >80 mg/dL, <21 years old, or Alcohol Use Disorders Identification Test ≥8. Significance was determined if p<0.05. Results: There were 705 pre-PIC and 840 post-PIC patients. Pre-PIC unscreened patients were more often uninsured (13% vs. 25%, p0.05). Overall, screening improved pre-PIC to post-PIC (52% vs. 88%, p<0.01) and the percentage of patients who screened positively also increased after PIC (8% vs. 23%, p<0.01). Brief intervention was unchanged (83% vs. 81%, p=1). Conclusion: The PIC is a novel tool that demonstrated improved alcohol screening and referral. It improved compliance with SBIRT and reduced implicit bias in the population screened. Utilization of a PIC is easily translatable to other centers and could become a national standard to advance performance improvement. Level of evidence: IV.
