Characterizing re-triage guidelines: A scoping review of states' rules and regulations.

BACKGROUND: State guidelines for re-triage, or emergency inter-facility transfer, have never been characterized across the United States. METHODS: All 50 states' Department of Health and/or Trauma System websites were reviewed for publicly available re-triage guidelines within their rules and regulations. Communication was made via phone or email to state agencies or trauma advisory committees to obtain or confirm the absence of guidelines where public data was unavailable. Guideline criteria were abstracted and grouped into domains of Center for Disease Control Field Triage Criteria: pattern/anatomy of injury, vital signs, special populations, and mechanisms of injury. Re-triage criteria were summarized across states using median and interquartile ranges for continuous data and frequencies for categorical data. Demographic data of states with and without re-triage guidelines were compared using the Wilcoxon rank sum test. RESULTS: Re-triage guidelines were identified for 22 of 50 states (44%). Common anatomy of injury criteria included head trauma (91% of states with guidelines), spinal cord injury (82%), chest injury (77%), and pelvic injury (73%). Common vital signs criteria included Glasgow Coma Score (91% of states) ranging from 8 to 14, systolic blood pressure (36%) ranging from 90 to 100 mm Hg, and respiratory rate (23%) with all using 10 respirations/minute. Common special populations criteria included mechanical ventilation (73% of states), age (68%) ranging from <2 or >60 years, cardiac disease (59%), and pregnancy (55%). No significant demographic differences were found between states with versus without re-triage guidelines. CONCLUSION: A minority of US states have re-triage guidelines. Characterizing existing criteria can inform future guideline development.

Is state trauma funding associated with mortality among injured hospitalized patients?

BACKGROUND: We sought to quantify the association between state trauma funding and (1) in-hospital mortality and (2) transfers of injured patients. METHODS: We conducted an observational cross-sectional study of states with publicly available trauma funding data. We analyzed in-hospital mortality using linked data from the Nationwide Inpatient Sample (NIS), American Hospital Association (AHA) Annual Survey, and these State Department of Public Health trauma funding data. RESULTS: A total of 594,797 injured adult patients were admitted to acute care hospitals in 17 states. Patients in states with >$1.00 per capita state trauma funding had 0.82 (95 â€‹% CI: 0.78-0.85, p â€‹< â€‹0.001) decreased adjusted odds of in-hospital mortality compared to patients in states with less than $1.00 per capita state trauma funding. CONCLUSIONS: Increased state trauma funding is associated with decreased adjusted in-hospital mortality.

Does Trauma Center Volume Account for the Association Between Trauma Center Verification Level and In-Hospital Mortality among Children Injured by Firearms in California?

BACKGROUND: Heterogeneity in trauma center designation and injury volume offer possible explanations for inconsistencies in pediatric trauma center designation's association with lower mortality among children. We hypothesized that rigorous trauma center verification, regardless of volume, would be associated with lower firearm injury-associated mortality in children. STUDY DESIGN: This retrospective cohort study leveraged the California Office of Statewide Health Planning and Development patient discharge data. Data from children aged 0 to 14 years in California from 2005 to 2018 directly transported with firearm injuries were analyzed. American College of Surgeons (ACS) trauma center verification level was the primary predictor of in-hospital mortality. Centers' annual firearm injury volume data were analyzed as a mediator of the association between center verification level and in-hospital mortality. Two mixed-effects multivariable logistic regressions modeled in-hospital mortality and the estimated association with center verification while adjusting for patient demographic and clinical characteristics. One model included the center's firearm injury volume and one did not. RESULTS: The cohort included 2,409 children with a mortality rate of 8.6% (n = 206). Adjusted odds of mortality were lower for children at adult level I (adjusted odds ratio [aOR] 0.38, 95% CI 0.19 to 0.80), pediatric (aOR 0.17, 95% CI 0.05 to 0.61), and dual (aOR 0.48, 95% CI 0.25 to 0.93) trauma centers compared to nontrauma/level III/IV centers. Firearm injury volume did not mediate the association between ACS trauma center verification and mortality (aOR/10 patient increase in volume 1.01, 95% CI 0.99 to 1.03). CONCLUSIONS: Trauma center verification level, regardless of firearm injury volume, was associated with lower firearm injury-associated mortality, suggesting that the ACS verification process is contributing to achieving optimal outcomes.

Geographic Disparities in Re-triage Destinations Among Seriously Injured Californians.

Objective: To quantify geographic disparities in sub-optimal re-triage of seriously injured patients in California. Summary of Background Data: Re-triage is the emergent transfer of seriously injured patients from the emergency departments of non-trauma and low-level trauma centers to, ideally, high-level trauma centers. Some patients are re-triaged to a second non-trauma or low-level trauma center (sub-optimal) instead of a high-level trauma center (optimal). Methods: This was a retrospective observational cohort study of seriously injured patients, defined by an Injury Severity Score > 15, re-triaged in California (2009-2018). Re-triages within one day of presentation to the sending center were considered. The sub-optimal re-triage rate was quantified at the state, regional trauma coordinating committees (RTCC), local emergency medical service agencies, and sending center level. A generalized linear mixed-effects regression quantified the association of sub-optimality with the RTCC of the sending center. Geospatial analyses demonstrated geographic variations in sub-optimal re-triage rates and calculated alternative re-triage destinations. Results: There were 8,882 re-triages of seriously injured patients and 2,680 (30.2 %) were sub-optimal. Sub-optimally re-triaged patients had 1.5 higher odds of transfer to a third short-term acute care hospital and 1.25 increased odds of re-admission within 60 days from discharge. The sub-optimal re-triage rates increased from 29.3 % in 2009 to 38.6 % in 2018. 56.0 % of non-trauma and low-level trauma centers had at least one sub-optimal re-triage. The Southwest RTCC accounted for the largest proportion (39.8 %) of all sub-optimal re-triages in California. Conclusion: High population density geographic areas experienced higher sub-optimal re-triage rates.

Re-triage moderates association between state trauma funding and lower mortality of trauma patients.

BACKGROUND: Severely injured patients who are re-triaged (emergently transferred from an emergency department to a high-level trauma center) experience lower in-hospital mortality. Patients in states with trauma funding also experience lower in-hospital mortality. This study examines the interaction of re-triage, state trauma funding, and in-hospital mortality. STUDY DESIGN: Severely injured patients (Injury Severity Score (ISS) >15) were identified from 2016 to 2017 Healthcare Cost and Utilization Project State Emergency Department Databases and State Inpatient Databases in five states (FL, MA, MD, NY, WI). Data were merged with the American Hospital Association Annual Survey and state trauma funding data. Patients were linked across hospital encounters to determine if they were appropriately field triaged, field under-triaged, optimally re-triaged, or sub-optimally re-triaged. A hierarchical logistic regression modeling in-hospital mortality was used to quantify the effect of re-triage on the association between state trauma funding and in-hospital mortality, while adjusting for patient and hospital characteristics. RESULTS: A total of 241,756 severely injured patients were identified. Median age was 52 years (IQR: 28, 73) and median ISS was 17 (IQR: 16, 25). Two states (MA, NY) allocated no funding, while three states (WI, FL, MD) allocated $0.09-$1.80 per capita. Patients in states with trauma funding were more broadly distributed across trauma center levels, with a higher proportion of patients brought to Level III, IV, or non-trauma centers, compared to patients in states without trauma funding (54.0% vs. 41.1%, p < 0.001). Patients in states with trauma funding were more often re-triaged, compared to patients in states without trauma funding (3.7% vs. 1.8%, p < 0.001). Patients who were optimally re-triaged in states with trauma funding experienced 0.67 lower adjusted odds of in-hospital mortality (95% CI: 0.50-0.89), compared to patients in states without trauma funding. We found that re-triage significantly moderated the association between state trauma funding and lower in-hospital mortality (p = 0.018). CONCLUSION: Severely injured patients in states with trauma funding are more often re-triaged and experience lower odds of mortality. Re-triage of severely injured patients may potentiate the mortality benefit of increased state trauma funding.

Defining obstacles to emergency transfer of trauma patients: An evaluation of retriage processes from nontrauma and lower-level Illinois trauma centers.

BACKGROUND: Retriage is the emergency transfer of severely injured patients from nontrauma and lower-level trauma centers to higher-level trauma centers. We identified the barriers to retriage at sending centers in a single health system. METHODS: We conducted a failure modes effects and criticality analysis at 4 nontrauma centers and 5 lower-level trauma centers in a single health system. Clinicians from each center described the steps in the trauma assessment and retriage process to create a process map. We used standardized scoring to characterize each failure based on frequency, impact on retriage, and prevention safeguards. We ranked each failure using the scores to calculate a risk priority number. RESULTS: We identified 26 steps and 93 failures. The highest-risk failure was refusal by higher-level trauma centers (receiving hospitals) to accept a patient. The most critical failures in the retriage process based on total risk, frequency, and safeguard scores were (1) refusal from a receiving higher-level trauma center to accept a patient (risk priority number = 191), (2) delay in a sending center's consultant examination of a patient in the emergency department (risk priority number = 177), and (3) delay in receiving hospital's consultant calling back (risk priority number = 177). CONCLUSION: We identified (1) addressing obstacles to determining clinical indications for retriage and (2) identifying receiving level I trauma centers who would accept the patient as opportunities to increase timely retriage. Establishing clear clinical indications for retriage that sending and receiving hospitals agree on represents an opportunity for intervention that could improve the retriage of injured patients.

The Association of Limited English Proficiency With Morbidity and Mortality After Trauma.

INTRODUCTION: Disparities following traumatic injury by race/ethnicity and insurance status are well-documented. However, the relationship between limited English proficiency (LEP) and outcomes after trauma is poorly understood. This study describes the association between LEP and morbidity and mortality after traumatic injury. METHODS: A retrospective cohort study was conducted of adult trauma patients admitted to a level 1 trauma center from 2012 to 2018. Morbidity (length of stay [LOS], intensive care unit admission, intensive care unit LOS, discharge destination) and in-hospital mortality for LEP and English proficient (EP) patients were compared using univariate and multivariable logistic and generalized linear models controlling for patient demographics (age, sex, race/ethnicity, insurance) and clinical characteristics (mechanism, activation level, Glasgow Coma Scale, Injury Severity Score, traumatic brain injury). RESULTS: Of the 13,104 patients, 16% were LEP patients. LEP languages included Chinese (44%) and Spanish (38%), and 18% categorized as "Other," including 33 languages. In multivariable models, LEP was statistically significantly associated with increased hospital LOS (P = 0.003) and increased discharge to home with home health services (P = 0.042) or to skilled nursing facility/rehabilitation (P = 0.006). Mortality rate was 7% for LEP versus 4% for EP patients (P < 0.0001). In multivariable analysis, speaking an LEP language other than Chinese or Spanish was statistically significantly associated with increased mortality compared to EP (P = 0.006). CONCLUSIONS: Following traumatic injury, LEP patients experience increased hospital LOS and are more frequently discharged to home with home health services or to skilled nursing facilities/rehabilitation. LEP patients speaking languages other than Chinese or Spanish experience increased mortality compared to EP patients.

Association of Race/Ethnicity With Substance Use Testing After Trauma: A Cross-Sectional Study.

INTRODUCTION: Race/ethnicity has been strongly associated with substance use testing but little is known about this association in injured patients. We sought to identify trends and associations between race/ethnicity and urine toxicology (UTox) or Blood Alcohol Concentration (BAC) testing in a diverse population after trauma. MATERIALS AND METHODS: We conducted a retrospective cross-sectional study of adult trauma patients admitted to a single Level-1 trauma center from 2012 to 2019. The prevalence of substance use testing was evaluated over time and analyzed using a multivariable logistic regression, with a subgroup analysis to evaluate the interaction of English language proficiency with race/ethnicity in the association of substance use testing. RESULTS: A total of 15,556 patients (40% White, 13% Black, 24% Latinx, 20% Asian, and 3% Native or Unknown) were included. BAC testing was done in 63.2% of all patients and UTox testing was done in 39.2%. The prevalence of substance use testing increased over time across all racial/ethnic groups. After adjustment, Latinx patients had higher odds of receiving a BAC test and Black patients had higher odds of receiving a UTox test (P < 0.001 and P < 0.001, respectively) compared to White patients. Asian patients had decreased odds of undergoing a UTox or BAC test compared to White patients (P < 0.001 and P < 0.001, respectively). Patients with English proficiency had higher odds of undergoing substance use testing compared to those with limited English proficiency (P < 0.001). CONCLUSIONS: Despite an increase in substance use testing over time, inequitable testing remained among racial/ethnic minorities. More work is needed to combat racial/ethnic disparities in substance use testing.

Limited English Proficiency Associated With Suboptimal Pain Assessment in Hospitalized Trauma Patients.

INTRODUCTION: Traumatic injury causes significant acute and chronic pain, and accurate pain assessment is foundational to optimal pain control. Prior literature has revealed disparities in the treatment of pain by race and ethnicity, but the effect of patient language on pain assessment remains unknown. We aimed to investigate the relationship between Limited English Proficiency (LEP) in pain assessment frequency and pain score magnitude for hospitalized trauma patients. METHODS: We conducted a cross-sectional, retrospective study including all hospitalized adult trauma patients from 2012 to 2018 at a single urban Level-1 trauma center. Patient language, 0-10 Numeric Rating Scale (NRS) pain scores, and demographic and clinical covariates were extracted from the electronic medical record. We used multivariable negative binomial regressions to compare NRS pain assessment frequency and multivariable linear regression to compare NRS pain score magnitude between LEP and English Proficient patients. RESULTS: Between 2012 and 2018, 9754 English proficient and 1878 LEP patients were hospitalized for traumatic injury. In multivariable models adjusted for demographic and injury characteristics, LEP patients had 2.4 fewer pain assessments per day compared to English proficient patients (7.21 versus 9.61, P = 0.001). Excluding days spent in the ICU, LEP patients had 2.6 fewer assessments per day (9.28 versus 11.88, P = 0.001). Median pain scores were lower in the LEP group (2.2 versus 3.61, P < 0.001), with a difference of 1.19 points in adjusted multivariable models. CONCLUSIONS: Compared to English Proficient patients, LEP patients had fewer pain assessments and lower NRS scores. Differences in pain assessment by patient language may be associated with disparities in pain management and morbidity.

Emergency general surgery utilization and disparities during COVID-19: an interrupted time-series analysis.

OBJECTIVE: We aimed to compare general surgery emergency (GSE) volume, demographics and disease severity before and during COVID-19. BACKGROUND: Presentations to the emergency department (ED) for GSEs fell during the early COVID-19 pandemic. Barriers to accessing care may be heightened, especially for vulnerable populations, and patients delaying care raises public health concerns. METHODS: We included adult patients with ED presentations for potential GSEs at a single quaternary-care hospital from January 2018 to August 2020. To compare GSE volumes in total and by subgroup, an interrupted time-series analysis was performed using the March shelter-in-place order as the start of the COVID-19 period. Bivariate analysis was used to compare demographics and disease severity. RESULTS: 3255 patients (28/week) presented with potential GSEs before COVID-19, while 546 (23/week) presented during COVID-19. When shelter-in-place started, presentations fell by 8.7/week (31%) from the previous week (p<0.001), driven by decreases in peritonitis (ß=-2.76, p=0.017) and gallbladder disease (ß=-2.91, p=0.016). During COVID-19, patients were younger (54 vs 57, p=0.001), more often privately insured (44% vs 38%, p=0.044), and fewer required interpreters (12% vs 15%, p<0.001). Fewer patients presented with sepsis during the pandemic (15% vs 20%, p=0.009) and the average severity of illness decreased (p<0.001). Length of stay was shorter during the COVID-19 period (3.91 vs 5.50 days, p<0.001). CONCLUSIONS: GSE volumes and severity fell during the pandemic. Patients presenting during the pandemic were less likely to be elderly, publicly insured and have limited English proficiency, potentially exacerbating underlying health disparities and highlighting the need to improve care access for these patients. LEVEL OF EVIDENCE: III.

Inequity in discharge pain management for trauma patients with limited English proficiency.

INTRODUCTION: Pain management is critical for optimal recovery after trauma. Previous work at our institution revealed differences in pain assessment by patient language, which may impact management. This study aimed to understand differences in discharge opioid prescribing for trauma patients with limited English proficiency (LEP). METHODS: We conducted a cross-sectional study of adult trauma patients discharged to the community from a diverse, urban level 1 trauma center in 2018. Opioid prescriptions were obtained from discharge pharmacy records and converted to standard oral morphine equivalents (OMEs). Multivariable logistic and quantile regression was used to examine the relationship between LEP, opioid prescriptions, and OMEs at discharge, controlling for demographic and clinical characteristics. RESULTS: Of 1,419 patients included in this study, 83% were English proficient (EP) and 17% were LEP. At discharge, 56% of EP patients received an opioid prescription, compared with 41% of LEP patients. In multivariable models, EP patients were 1.63 times more likely to receive any opioid prescription (95% CI, 1.17-2.25; p = 0.003). Mean OME was 147 for EP and 94 for LEP patients. In multivariable models, the difference between EP and LEP patients was 40 OMEs (95% CI, 21.10-84.22; p = 0.004). In adjusted quantile regression models, differences in total OMEs increased with the amount of OMEs prescribed. There was no difference in OMEs at the 20th and 40th percentile of total OMEs, but LEP patients received 26 fewer OMEs on average at the 60th percentile (95% CI, -3.23 to 54.90; p = 0.081) and 45 fewer OMEs at the 80th percentile (95% CI, 5.48-84.48; p = 0.026). CONCLUSION: Limited English proficiency patients with traumatic injuries were less likely to receive any opioid prescription and were prescribed lower quantities of opiates, which could contribute to suboptimal pain management and recovery. Addressing these disparities is an important focus for future quality improvement efforts. LEVEL OF EVIDENCE: Care Management, level IV.

Surviving traumatic injury, only to die of acute drug poisoning: Should trauma centers be a path for intervention?

BACKGROUND: Although death from drug overdose is a leading cause of injury-related death in the United States, its incidence after traumatic incident is unknown. Moreover, little is known about related risk factors. We sought to determine the incidence and characteristics of and risk factors for trauma patients suffering death by acute drug poisoning ("overdose") after hospitalization for a traumatic incident. METHODS: We conducted a retrospective chart review of all admitted trauma patients ≥18 y of age at the only level-1 trauma center in our region from 2012 to 2019, matched with unintentional overdose decedents from the California death registry. We assessed associations between demographic and clinical characteristics with risk of overdose death, using cumulative incidence functions and Fine-Gray subdistribution hazard models. RESULTS: Of 9,860 patients residing in San Francisco, CA, USA, at the time of their trauma activation or admission during the study period, 1,418 died (4.3 per 100 person-years), 107 from unintentional overdose (0.3 per 100 person-years). Overdose decedents were 84% male, 50% white, with a mean age of 48 years at the time of presentation; 20% of deaths occurred within 3 months of hospitalization, and 40% were attributed to a prescription opioid. In multivariate analysis, younger age, male sex, white race, and having undergone a urine drug screening were all associated with subsequent death from overdose. CONCLUSION: During a mean 3.4-year follow-up, the mortality rate from overdose among adult patients with traumatic incidents was 0.3/100 person-years. Trauma hospitalization may serve as an opportunity to screen and initiate prevention, harm reduction, and treatment interventions.

The DISTANCE study: Determining the impact of social distancing on trauma epidemiology during the COVID-19 epidemic-An interrupted time-series analysis.

BACKGROUND: The large-scale social distancing efforts to reduce SARS-CoV-2 transmission have dramatically changed human behaviors associated with traumatic injuries. Trauma centers have reported decreases in trauma volume, paralleled by changes in injury mechanisms. We aimed to quantify changes in trauma epidemiology at an urban Level I trauma center in a county that instituted one of the earliest shelter-in-place orders to inform trauma care during future pandemic responses. METHODS: A single-center interrupted time-series analysis was performed to identify associations of shelter-in-place with trauma volume, injury mechanisms, and patient demographics in San Francisco, California. To control for short-term trends in trauma epidemiology, weekly level data were analyzed 6 months before shelter-in-place. To control for long-term trends, monthly level data were analyzed 5 years before shelter-in-place. RESULTS: Trauma volume decreased by 50% in the week following shelter-in-place (p < 0.01), followed by a linear increase each successive week (p < 0.01). Despite this, trauma volume for each month (March-June 2020) remained lower compared with corresponding months for all previous 5 years (2015-2019). Pediatric trauma volume showed similar trends with initial decreases (p = 0.02) followed by steady increases (p = 0.05). Reductions in trauma volumes were due entirely to changes in nonviolent injury mechanisms, while violence-related injury mechanisms remained unchanged (p < 0.01). CONCLUSION: Although the shelter-in-place order was associated with an overall decline in trauma volume, violence-related injuries persisted. Delineating and addressing underlying factors driving persistent violence-related injuries during shelter-in-place orders should be a focus of public health efforts in preparation for future pandemic responses. LEVEL OF EVIDENCE: Epidemiological study, level III.

Describing the density of high-level trauma centers in the 15 largest US cities.

BACKGROUND: There has been a proliferation of urban high-level trauma centers. The aim of this study was to describe the density of high-level adult trauma centers in the 15 largest cities in the USA and determine whether density was correlated with urban social determinants of health and violence rates. METHODS: The largest 15 US cities by population were identified. The American College of Surgeons' (ACS) and states' department of health websites were cross-referenced for designated high-level (levels 1 and 2) trauma centers in each city. Trauma centers and associated 20 min drive radius were mapped. High-level trauma centers per square mile and per population were calculated. The distance between high-level trauma centers was calculated. Publicly reported social determinants of health and violence data were tested for correlation with trauma center density. RESULTS: Among the 15 largest cities, 14 cities had multiple high-level adult trauma centers. There was a median of one high-level trauma center per every 150 square kilometers with a range of one center per every 39 square kilometers in Philadelphia to one center per596 square kilometers in San Antonio. There was a median of one high-level trauma center per 285 034 people with a range of one center per 175 058 people in Columbus to one center per 870 044 people in San Francisco. The median minimum distance between high-level trauma centers in the 14 cities with multiple centers was 8 kilometers and ranged from 1 kilometer in Houston to 43 kilometers in San Antonio. Social determinants of health, specifically poverty rate and unemployment rate, were highly correlated with violence rates. However, there was no correlation between trauma center density and social determinants of health or violence rates. DISCUSSION: High-level trauma centers density is not correlated with social determinants of health or violence rates. LEVEL OF EVIDENCE: VI. STUDY TYPE: Economic/decision.

Pelvic fracture pattern predicts the need for hemorrhage control intervention-Results of an AAST multi-institutional study.

BACKGROUND: Early identification of patients with pelvic fractures at risk of severe bleeding requiring intervention is critical. We performed a multi-institutional study to test our hypothesis that pelvic fracture patterns predict the need for a pelvic hemorrhage control intervention. METHODS: This prospective, observational, multicenter study enrolled patients with pelvic fracture due to blunt trauma. Inclusion criteria included shock on admission (systolic blood pressure <90 mm Hg or heart rate >120 beats/min and base deficit >5, and the ability to review pelvic imaging). Demographic data, open pelvic fracture, blood transfusion, pelvic hemorrhage control intervention (angioembolization, external fixator, pelvic packing, and/or REBOA [resuscitative balloon occlusion of the aorta]), and mortality were recorded. Pelvic fracture pattern was classified according to Young-Burgess in a blinded fashion. Predictors of pelvic hemorrhage control intervention and mortality were analyzed by univariate and multivariate regression analyses. RESULTS: A total of 163 patients presenting in shock were enrolled from 11 Level I trauma centers. The most common pelvic fracture pattern was lateral compression I, followed by lateral compression I, and vertical shear. Of the 12 patients with an anterior-posterior compression III fracture, 10 (83%) required a pelvic hemorrhage control intervention. Factors associated with the need for pelvic fracture hemorrhage control intervention on univariate analysis included vertical shear pelvic fracture pattern, increasing age, and transfusion of blood products. Anterior-posterior compression III fracture patterns and open pelvic fracture predicted the need for pelvic hemorrhage control intervention on multivariate analysis. Overall in-hospital mortality for patients admitted in shock with pelvic fracture was 30% and did not differ based on pelvic fracture pattern on multivariate analysis. CONCLUSION: Blunt trauma patients admitted in shock with anterior-posterior compression III fracture patterns or patients with open pelvic fracture are at greatest risk of bleeding requiring pelvic hemorrhage control intervention. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.

The Triage of Injured Patients: Mechanism of Injury, Regardless of Injury Severity, Determines Hospital Destination.

The target rate for trauma undertriage is <5 per cent, but rates are as high as 30 to 40 per cent in many trauma systems. We hypothesized that high undertriage rates were due to the tendency to undertriage injured elderly patients and a growing elderly population. We conducted a retrospective analysis of all hospital visits in California using the Office of Statewide Health Planning and Development Database over a 5-year period. All hospital admissions and emergency department visits associated with injury were longitudinally linked. The primary outcome was triage pattern. Triage patterns were stratified across three dimensions: age, mechanism of injury, and access to care. A total of 60,182 severely injured patients were included in the analysis. Fall-related injuries were frequently undertriaged compared with injuries from motor vehicle collisions (MVCs) and penetrating trauma (52% vs 12% and 10%, respectively). This pattern was true for all age groups. Conversely, MVCs and penetrating traumas were associated with high rates of overtriage (>70% for both). In conclusion, in contrast to our hypothesis, we found that triage is largely determined by mechanism of injury regardless of injury severity. High rates of undertriage are largely due to the undertriage of fall-related injuries, which occurs in both younger and older adults. Patients injured after MVCs and penetrating trauma victims are brought to trauma centers regardless of injury severity, resulting in high rates of overtriage. These findings suggest an opportunity to improve trauma system performance.

Current management of hemorrhage from severe pelvic fractures: Results of an American Association for the Surgery of Trauma multi-institutional trial.

BACKGROUND: There is no consensus as to the optimal treatment paradigm for patients presenting with hemorrhage from severe pelvic fracture. This study was established to determine the methods of hemorrhage control currently being used in clinical practice. METHODS: This prospective, observational multi-center study enrolled patients with pelvic fracture from blunt trauma. Demographic data, admission vital signs, presence of shock on admission (systolic blood pressure < 90 mm Hg or heart rate > 120 beats per minute or base deficit < -5), method of hemorrhage control, transfusion requirements, and outcome were collected. RESULTS: A total of 1,339 patients with pelvic fracture were enrolled from 11 Level I trauma centers. Fifty-seven percent of the patients were male, with a mean ± SD age of 47.1 ± 21.6 years, and Injury Severity Score (ISS) of 19.2 ± 12.7. In-hospital mortality was 9.0 %. Angioembolization and external fixator placement were the most common method of hemorrhage control used. A total of 128 patients (9.6%) underwent diagnostic angiography with contrast extravasation noted in 63 patients. Therapeutic angioembolization was performed on 79 patients (5.9%). There were 178 patients (13.3%) with pelvic fracture admitted in shock with a mean ± SD ISS of 28.2 ± 14.1. In the shock group, 44 patients (24.7%) underwent angiography to diagnose a pelvic source of bleeding with contrast extravasation found in 27 patients. Thirty patients (16.9%) were treated with therapeutic angioembolization. Resuscitative endovascular balloon occlusion of the aorta was performed on five patients in shock and used by only one of the participating centers. Mortality was 32.0% for patients with pelvic fracture admitted in shock. CONCLUSION: Patients with pelvic fracture admitted in shock have high mortality. Several methods were used for hemorrhage control with significant variation across institutions. The use of resuscitative endovascular balloon occlusion of the aorta may prove to be an important adjunct in the treatment of patients with severe pelvic fracture in shock; however, it is in the early stages of evaluation and not currently used widely across trauma centers. LEVEL OF EVIDENCE: Prognostic study, level II; therapeutic study, level III.

Reconsidering the Resources Needed for Multiple Casualty Events: Lessons Learned From the Crash of Asiana Airlines Flight 214.

IMPORTANCE: To date, a substantial portion of multiple casualty incident literature has focused exclusively on prehospital and emergency department resources needed for optimal disaster response. Thus, inpatient resources required to care for individuals injured in multiple casualty events are not well described. OBJECTIVE: To highlight the resources beyond initial emergency department triage needed for multiple casualty events, using one of the largest commercial aviation disasters in modern US history as a case study. DESIGN, SETTING, AND PARTICIPANTS: Prospective case series of injured individuals treated at an urban level I trauma center following the crash of Asiana Airlines flight 214 on July 6, 2013. This analysis was conducted between June 1, 2014, and December 1, 2015. EXPOSURE: Commercial jetliner crash. MAIN OUTCOMES AND MEASURES: Medical records, imaging data, nursing overtime, blood bank records, and trauma registry data were analyzed. Disaster logs, patient injuries, and blood product data were prospectively collected during the incident. RESULTS: Among 307 people aboard the flight, 192 were injured; 63 of the injured patients were initially evaluated at San Francisco General Hospital and Trauma Center (the highest number at any of the receiving medical facilities; age range, 4-74 years [23 were aged <17 years and 3 were aged >60 years]; median injury severity score of 19 admitted patients, 9 [range, 9-45]), including the highest number of critically injured patients (10 of 12). Despite the high impact of the crash, only 3 persons (<1%) died, including 1 in-hospital death. Among the 63 patients, 32 (50.8%) underwent a computed tomographic imaging study, with imaging of the abdomen and pelvis being the most common. Sixteen of the 32 patients undergoing computed tomography (50.0%) had a positive finding on at least 1 scan. Nineteen patients had major injuries and required admission, with 5 taken directly from the emergency department to the operating room. The most frequent injury was spinal fracture (13 patients). In the first 48 hours, 15 operations were performed and 117 total units of blood products were transfused. A total of 370 nursing overtime hours were required to treat the injured patients on the day of the event. CONCLUSIONS AND RELEVANCE: Proper disaster preparedness requires attention to hospital-level needs beyond initial emergency department triage. The Asiana Airlines flight 214 crash highlights the need to plan for high use of advanced imaging, blood products, operating room availability, nursing resources, and management of inpatient hospital beds.
