Addressing disparities is crucial for enhancing population health, ensuring health security, and fostering resilient health systems. Disparities in acute care surgery (trauma, emergency general surgery, and surgical critical care) have been well documented and the magnitude of inequities demand an intentional, organized, and effective response. As part of its commitment to achieve high-quality, equitable care in all aspects of acute care surgery, the American Association for the Surgery of Trauma convened an expert panel at its eigty-second annual meeting in September 2023 to discuss how to take action to work towards health equity in acute care surgery practice. The panel discussion framed contemporary disparities in the context of historic and political injustices, then identified targets for interventions and potential action items in health system structure, health policy, the surgical workforce, institutional operations and quality efforts. We offer a four-pronged approach to address health inequities: identify, reduce, eliminate, and heal disparities, with the goal of building a healthcare system that achieves equity and justice for all.

OBJECTIVE:This study aimed to determine whether lower extremity fracture fixation technique and timing (≤24 vs. >24 hours) impact neurologic outcomes in TBI patients. METHODS:A prospective observational study was conducted across 30 trauma centers. Inclusion criteria were age 18 years and older, head Abbreviated Injury Scale (AIS) score of >2, and a diaphyseal femur or tibia fracture requiring external fixation (Ex-Fix), intramedullary nailing (IMN), or open reduction and internal fixation (ORIF). The analysis was conducted using analysis of variamce, Kruskal-Wallis, and multivariable regression models. Neurologic outcomes were measured by discharge Ranchos Los Amigos Revised Scale (RLAS-R). RESULTS:Of the 520 patients enrolled, 358 underwent Ex-Fix, IMN, or ORIF as definitive management. Head AIS was similar among cohorts. The Ex-Fix group experienced more severe lower extremity injuries (AIS score, 4-5) compared with the IMN group (16% vs. 3%, p = 0.01) but not the ORIF group (16% vs. 6%, p = 0.1). Time to operative intervention varied between the cohorts with the longest time to intervention for the IMN group (median hours: Ex-Fix, 15 [8-24] vs. ORIF, 26 [12-85] vs. IMN, 31 [12-70]; p < 0.001). The discharge RLAS-R score distribution was similar across the groups. After adjusting for confounders, neither method nor timing of lower extremity fixation influenced the discharge RLAS-R. Instead, increasing age and head AIS score were associated with a lower discharge RLAS-R score (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.002-1.03 and OR, 2.37; 95% CI, 1.75-3.22), and a higher Glasgow Coma Scale motor score on admission (OR, 0.84; 95% CI, 0.73-0.97) was associated with higher RLAS-R score at discharge. CONCLUSION:Neurologic outcomes in TBI are impacted by severity of the head injury and not the fracture fixation technique or timing. Therefore, the strategy of definitive fixation of lower extremity fractures should be dictated by patient physiology and the anatomy of the injured extremity and not by the concern for worsening neurologic outcomes in TBI patients. LEVEL OF EVIDENCE:Prognostic and Epidemiological; Level III.

BACKGROUND:Alcohol and drug use (substance use) is a risk factor for crash involvement. OBJECTIVES:To assess the association between substance use and crash injury severity among older adults and how the relationship differs by rurality/urbanicity. METHODS:We pooled 2017-2021 cross-sectional data from the United States National Emergency Medical Service (EMS) Information System. We measured injury severity (low acuity, emergent, critical, and fatal) predicted by substance use, defined as self-reported or officer-reported alcohol and/or drug use. We controlled for age, sex, race/ethnicity, road user type, anatomical injured region, roadway crash, rurality/urbanicity, time of the day, and EMS response time. We performed a partial proportional ordinal logistic regression and reported the odds of worse injury outcomes (emergent, critical, and fatal injuries) compared to low acuity injuries, and the predicted probabilities by rurality/urbanicity. RESULTS:Our sample consisted of 252,790 older adults (65 years and older) road users. Approximately 67%, 25%, 6%, and 1% sustained low acuity, emergent, critical, and fatal injuries, respectively. Substance use was reported in approximately 3% of the population, and this proportion did not significantly differ by rurality/urbanicity. After controlling for patient, crash, and injury characteristics, substance use was associated with 36% increased odds of worse injury severity. Compared to urban areas, the predicted probabilities of emergent, critical, and fatal injuries were higher in rural and suburban areas. CONCLUSION:Substance use is associated with worse older adult crash injury severity and the injury severity is higher in rural and suburban areas compared to urban areas.

Health equity is defined as the sixth domain of healthcare quality. Understanding health disparities in acute care surgery (defined as trauma surgery, emergency general surgery and surgical critical care) is key to identifying targets that will improve outcomes and ensure delivery of high-quality care within healthcare organizations. Implementing a health equity framework within institutions such that local acute care surgeons can ensure equity is a component of quality is imperative. Recognizing this need, the AAST (American Association for the Surgery of Trauma) Diversity, Equity and Inclusion Committee convened an expert panel entitled 'Quality Care is Equitable Care' at the 81st annual meeting in September 2022 (Chicago, Illinois). Recommendations for introducing health equity metrics within health systems include: (1) capturing patient outcome data including patient experience data by race, ethnicity, language, sexual orientation, and gender identity; (2) ensuring cultural competency (eg, availability of language services; identifying sources of bias or inequities); (3) prioritizing health literacy; and (4) measuring disease-specific disparities such that targeted interventions are developed and implemented. A stepwise approach is outlined to include health equity as an organizational quality indicator.

Exsanguination remains the leading cause of preventable death among victims of trauma. For adult and pediatric trauma patients in the prehospital phase of care, methods to control hemorrhage and hemostatic resuscitation are described in this joint consensus opinion by the American College of Surgeons Committee on Trauma, the American College of Emergency Physicians, and the National Association of EMS Physicians.
