Prospective validation of a hospital triage predictive model to decrease undertriage: an EAST multicenter study.

Background: Tiered trauma team activation (TTA) allows systems to optimally allocate resources to an injured patient. Target undertriage and overtriage rates of <5% and <35% are difficult for centers to achieve, and performance variability exists. The objective of this study was to optimize and externally validate a previously developed hospital trauma triage prediction model to predict the need for emergent intervention in 6 hours (NEI-6), an indicator of need for a full TTA. Methods: The model was previously developed and internally validated using data from 31 US trauma centers. Data were collected prospectively at five sites using a mobile application which hosted the NEI-6 model. A weighted multiple logistic regression model was used to retrain and optimize the model using the original data set and a portion of data from one of the prospective sites. The remaining data from the five sites were designated for external validation. The area under the receiver operating characteristic curve (AUROC) and the area under the precision-recall curve (AUPRC) were used to assess the validation cohort. Subanalyses were performed for age, race, and mechanism of injury. Results: 14 421 patients were included in the training data set and 2476 patients in the external validation data set across five sites. On validation, the model had an overall undertriage rate of 9.1% and overtriage rate of 53.7%, with an AUROC of 0.80 and an AUPRC of 0.63. Blunt injury had an undertriage rate of 8.8%, whereas penetrating injury had 31.2%. For those aged ≥65, the undertriage rate was 8.4%, and for Black or African American patients the undertriage rate was 7.7%. Conclusion: The optimized and externally validated NEI-6 model approaches the recommended undertriage and overtriage rates while significantly reducing variability of TTA across centers for blunt trauma patients. The model performs well for populations that traditionally have high rates of undertriage. Level of evidence: 2.

Isolated injury, Charlson Comorbidity Index, and transfer from another facility are associated with delay in antibiotic administration: a retrospective study of 963 patients with open fractures.

Purpose: To identify factors associated with delays in administration and pharmacy and nursing preparation of antibiotics for patients with open fractures. Design: Retrospective review. Setting: Level I trauma center. Patients: Nine hundred sixty-three adults with open fractures administered antibiotics. Main Outcome Measurements: Delay in antibiotic administration greater than 66 minutes from arrival and significant pharmacy-related and nursing-related delay. Results: Isolated injury, Charlson Comorbidity Index, and transfer from another facility were associated with delay in antibiotic administration greater than 66 minutes. Injury Severity Score, transfer, and trauma team activation were associated with pharmacy-related or nursing-related delay. Conclusion: Interventions to reduce antibiotic administration time for open fractures should focus on early identification of open fractures and standardization of antibiotic protocols to ensure timely administration even in complex or resource-scarce care situations. Level of Evidence: Prognostic level III.

Does Scheduled Low-Dose Short-Term NSAID (Ketorolac) Modulate Cytokine Levels After Orthopaedic Polytrauma? A Secondary Analysis of a Randomized Clinical Trial.

OBJECTIVES: To determine whether scheduled low-dose, short-term ketorolac modulates cytokine concentrations in orthopaedic polytrauma patients. DESIGN: Secondary analysis of a double-blinded, randomized controlled trial. SETTING: Single Level I trauma center from August 2018 to October 2022. PATIENT SELECTION CRITERIA: Orthopaedic polytrauma patients between 18 and 75 years with a New Injury Severity Score greater than 9 were enrolled. Participants were randomized to receive 15 mg of intravenous ketorolac every 6 hours for up to 5 inpatient days or 2 mL of intravenous saline similarly. OUTCOME MEASURES AND COMPARISONS: Daily concentrations of prostaglandin E2 and interleukin (IL)-1a, IL-1b, IL-6, and IL-10. Clinical outcomes included hospital and intensive care unit length of stay, pulmonary complications, and acute kidney injury. RESULTS: Seventy orthopaedic polytrauma patients were enrolled, with 35 participants randomized to the ketorolac group and 35 to the placebo group. The overall IL-10 trend over time was significantly different in the ketorolac group ( P = 0.043). IL-6 was 65.8% higher at enrollment compared to day 3 ( P < 0.001) when aggregated over both groups. There was no significant treatment effect for prostaglandin E2, IL-1a, or IL-1b ( P > 0.05). There were no significant differences in clinical outcomes between groups ( P > 0.05). CONCLUSIONS: Scheduled low-dose, short-term, intravenous ketorolac was associated with significantly different mean trends in IL-10 concentration in orthopaedic polytrauma patients with no significant differences in prostaglandin E2, IL-1a, IL-1b, or IL-6 levels between groups. The treatment did not have an impact on clinical outcomes of hospital or intensive care unit length of stay, pulmonary complications, or acute kidney injury. LEVEL OF EVIDENCE: Therapeutic Level II.

Fragmenting projectiles: a case report and literature review of the G2 Radically Invasive Projectile.

Innovations in projectile design present unique challenges for trauma surgeons when treating gunshot victims. The G2 Radically Invasive Projectile (G2 Research, Winder, Georgia, USA) (G2RIP) is a frangible, rapidly expanding bullet resulting in a distinct pattern of injury consisting of diffuse hemorrhage with multicavity trauma as well as unique radiographic features of the projectile. To efficiently manage patients injured by the G2RIP, trauma surgeons must be aware of these distinct characteristics, and of previous patterns in effective management such as liberal damage control and extensive use of CT. Understanding previous presentation and management of patients injured by the G2RIP can aid in improving patient care in the trauma center.

Optimal strategies for assessing and managing pain, agitation, and delirium in the critically ill surgical patient: What you need to know.

ABSTRACT: Pain, agitation, and delirium (PAD) are primary drivers of outcome in the ICU, and expertise in managing these entities successfully is crucial to the intensivist's toolbox. In addition, there are unique aspects of surgical patients that impact assessment and management of PAD. In this review, we address the continuous spectrum of assessment, and management of critically ill surgical patients, with a focus on limiting PAD, particularly incorporating mobility as an anchor to ICU liberation. Finally, we touch on the impact of PAD in specific populations, including opioid use disorder, traumatic brain injury, pregnancy, obesity, alcohol withdrawal, and geriatric patients. The goal of the review is to provide rapid access to information regarding PAD and tools to assess and manage these important elements of critical care of surgical patients.

Liver Transplantation for Severe Hepatic Trauma: a multicenter analysis from the UNOS dataset.

BACKGROUND: Orthotopic liver transplantation (OLT) is rarely indicated after hepatic trauma but it can be the only therapeutic option in some patients. There are scarce data analyzing the surgical outcomes of OLT after trauma. METHODS: We used the UNOS dataset to identify patients who underwent OLT for trauma from 1987 to 2022, and compared them to a cohort of patients transplanted for other indications. Cox proportional hazard and multivariable logistic regression analyses were performed to assess predictors of graft and patient survival. RESULTS: 72 patients underwent OLT for trauma during the study period. Patients with trauma were more frequently on mechanical ventilation at the time of transplantation (26.4% vs. 7.6%, p < 0.001) and had a greater incidence of pre-transplant portal vein thrombosis (PVT) (12.5% vs. 4%, p = 0.002). Our 4:1 matched analysis showed that trauma patients had significantly shorter wait times, higher incidence of pre-transplant PVT and prolonged length of stay (LOS). Trauma was associated with decreased overall graft survival (HR = 1.42, 95% CI = 1.01-1.98), and increased LOS (p = 0.048). There were no significant differences in long term patient survival. CONCLUSION: Unique physiological and vascular challenges after severe hepatic trauma might be associated with decreased graft survival in patients requiring liver transplantation.

Common postbariatric surgery emergencies for the acute care surgeon: What you need to know.

ABSTRACT: The field of bariatric and metabolic surgery has changed rapidly over the past two decades, with an exponential increase in case volumes being performed because of its proven efficacy for morbid obesity and obesity-related comorbidities. Although this increased volume of procedures has been accompanied by significant decrease in postoperative complication rates, there are numerous potential complications after bariatric surgery that may require urgent or emergent surgical evaluation or interventions. Many of these risks extend well beyond the early postoperative period and can present months to years after the index procedure. Acute care surgeons are increasingly covering most or all of the emergency general surgery services at many centers and must be familiar with the numerous bariatric surgical procedures being performed and their individual complication profile to provide optimal care for these frequently challenging patients. This article provides a focused and concise review of the common bariatric procedures being performed, their early and late complication profiles, and a practical guide to the optimal diagnostic evaluations, surgical interventions, and perioperative management options. The author group includes both acute care surgeons and bariatric surgeons with significant experience in the emergency management of the complicated postbariatric surgical patient.

Timing of venous thromboembolism prophylaxis initiation after injury: Findings from the consensus conference to implement optimal VTE prophylaxis in trauma.

ABSTRACT: Optimizing prophylaxis against venous thromboembolic events (VTEs) is a critical issue in the care of injured patients. Although these patients are at significant risk of developing VTE, they also present competing concerns related to exacerbation of bleeding from existing injuries. Especially after high-risk trauma, including injuries to the abdominal solid organs, brain, and spine, trauma providers must delineate the time period in which VTE prophylaxis successfully reduces VTE rates without encouraging bleeding. Although existing data are primarily retrospective in nature and further study is required, literature supports early VTE chemoprophylaxis initiation even for severely injured patients. Early initiation is most frequently defined as <48 hours from admission but varies from <24 hours to 72 hours and occasionally refers to time from initial trauma. Prior to chemical VTE prophylaxis initiation in patients at risk for bleeding, an observation period is necessary during which injuries must show themselves to be hemostatic, either clinically or radiographically. In the future, prospective examination of optimal timing of VTE prophylaxis is necessary. Further study of specific subsets of trauma patients will allow for development of effective VTE mitigation strategies based upon collective risks of VTE and hemorrhage progression.

Prehospital shock index predicts outcomes after prolonged transport: A multicenter rural study.

BACKGROUND: Shock index (SI) predicts outcomes after trauma. Prior single-center work demonstrated that emergency medical services (EMSs) initial SI was the most accurate predictor of hospital outcomes in a rural environment. This study aimed to evaluate the predictive ability of SI in multiple rural trauma systems with prolonged transport times to a definitive care facility. METHODS: This retrospective review was performed at four American College of Surgeons-verified level 1 trauma centers with large rural catchment basins. Adult trauma patients who were transferred and arrived >60 minutes from scene during 2018 were included. Patients who sustained blunt chest or abdominal trauma were analyzed. Subjects with missing data or severe head trauma (Abbreviated Injury Scale score, >2) were excluded. Poisson and binomial logistic regression were used to study the effect of SI and delta shock index (∆SI) on outcomes. RESULTS: After applying the criteria, 789 patients were considered for analysis (502 scene patients and 287 transfers). The mean Injury Severity Score was 8 (interquartile range, 6) for scene and 8.9 (interquartile range, 5) for transfers. Initial EMSs SI was a significant predictor of the need for blood transfusion and intensive care unit care in both scene and transferred patients. An increase in ∆SI was predictive of the need for operative intervention ( p < 0.05). There were increased odds for mortality for every 0.1 change in EMSs SI; those changes were not deemed significant among both scene and transfer patients ( p < 0.1). CONCLUSION: Providers must maintain a high level of clinical suspicion for patients who had an initially elevated SI. Emergency medical services SI is a significant predictor for use of blood and intensive care unit care, as well as mortality for scene patients. This highlights the importance of SI and ∆SI in rural trauma care. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

A multicenter evaluation on the impact of non-therapeutic transfer in rural trauma.

INTRODUCTION: Trauma transfers are a common occurrence in rural areas, where critical access and lower-level trauma centers routinely transfer to tertiary care centers for specialized care. Transfers are non-therapeutic (NTT) when no specialist intervention occurs, leading to transfer that were futile (FT) or secondary overtriage (SOT). This study aimed to evaluate the prevalence of NTT among four trauma centers providing care to rural Appalachia. METHODS: This retrospective review was performed at four, ACS verified, Level 1 trauma centers. All adult trauma patients, transferred during 2018 were included for analysis. Transfers were considered futile if in <48 h the patient died or was discharged to hospice, without operative intervention. SOT transfers were discharged in <48 h, without major intervention, with an ISS< 15. Cost analysis was performed to describe the impact of NTT on EMS use. RESULTS: 4,189 patients were analyzed during the study period. 105 (2.5%) met criteria for futility. Futile patients had a median ISS of 25 (IQR 9-26), and 48% had an AIS head ≥4. These were significantly greater (p<0.001) than non-futile transfers, median ISS 5 (IQR 2-9), 3% severe head injury. SOT occurred in 1371 (33%), median ISS of 5, and lower AIS scores by region. Isolated facial injuries resulted in 165 transfers. 13% of FT+SOT were admitted to the ICU. Only 22% of FT+SOT came from a trauma center. 68% were transported by ALS and 13% transported by air transport. FT+SOT traveled on average 70 miles from their home to receive care. CONCLUSIONS: Non-therapeutic transfers account for more than 1/3 of transfers in this rural environment. There was a significant use of advanced life support and aeromedical transport. The utility of these transfers should be questioned. With the recent increases in telehealth there is an opportunity for trauma systems to improve regional care and decrease transfers for futile cases.

Variability in hospital costs for short stay emergent laparoscopic appendectomy.

Background: Acute care surgery (ACS) diagnoses including appendicitis comprise 20% of inpatient admissions in the U.S. and 25% of hospital costs. To inform cost reduction efforts, we sought to measure variability in hospital costs for short stay emergent laparoscopic appendectomy. Methods: VIZIENT Clinical Data Base was queried for adult and pediatric patients who underwent emergent laparoscopic appendectomy for appendicitis with length of stay ≤3 days. We extracted calendar FY 2019 direct costs (DC) by age group and diagnosis code for sites reporting at least 5 cases. Costs in the database are derived from actual charges multiplied by a site- and cost center-specific cost-to-charge ratio. Labor portions are scaled by the area wage index. Sites were ranked by vigintile of DC per case to provide confidentiality and blinding. Results: In a total of 128 hospitals, median number of cases per site was 35.5 (Interquartile range (IQR) 20-65) with a total of 6585 cases analyzed. Highest cost centers by descending order were OR, Medical/Surgical Supplies, Routine Floor Care, Pharmacy, Emergency Room, Anesthesia, Laboratory, and CT scans, with all others each less than 2% of total costs. The relation between OR costs and total costs was strong but not complete. Mean DC per case was $4609. DC did not correlate with age, diagnosis code, or case volume per site. Conclusions: Wide variation in cost of laparoscopic appendectomy among medical centers suggests potential for significant cost reduction. Strategic opportunities in cost reduction appear to lie inside and outside the OR. Key message: Wide variation in cost of laparoscopic appendectomy and individual cost centers suggest a multi-pronged cost-reduction strategy should be used.

History of Equity, Diversity, and Inclusion in Trauma Surgery: for Our Patients, for Our Profession, and for Ourselves.

Purpose of Review: Disparities exist in outcome after injury, particularly related to race, ethnicity, socioeconomics, geography, and age. The mechanisms for this outcome disparity continue to be investigated. As trauma care providers, we are challenged to be mindful of and mitigate the impact of these disparities so that all patients realize the same opportunities for recovery. As surgeons, we also have varied professional experiences and opportunities for achievement and advancement depending upon our gender, ethnicity, race, religion, and sexual orientation. Even within a profession associated with relative affluence, socioeconomic status conveys different professional opportunities for surgeons. Recent Findings: Fortunately, the profession of trauma surgery has undergone significant progress in raising awareness of patient and professional inequity among trauma patients and surgeons and has implemented systematic changes to diminish these inequities. Herein we will discuss the history of equity and inclusion in trauma surgery as it has affected our patients, our profession, and our individual selves. Summary: Our goal is to provide a historical context, a status report, and a list of key initiatives or objectives on which all of us must focus. In doing so, the best possible clinical outcomes can be achieved for patients and the best professional and personal "outcomes" can be achieved for practicing and future trauma surgeons.

An analysis of police transport in an Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Police transport (PT) of penetrating trauma patients in urban locations has become routine in certain metropolitan areas; however, whether it results in improved outcomes over prehospital Advanced life support (ALS) transport has not been determined in a multicenter study. We hypothesized that PT would not result in improved outcomes. METHODS: This was a multicenter, prospective, observational study of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. Police transport and ALS patients were allocated via nearest neighbor, propensity matching. Transport mode also examined by Cox regression. RESULTS: Of 1,618 total patients, 294 (18.2%) had PT and 1,324 (81.8%) were by ALS. After matching, 588 (294/cohort) remained. The patients were primarily Black (n = 497, 84.5%), males (n = 525, 89.3%, injured by gunshot wound (n = 494, 84.0%) with 34.5% (n = 203) having Injury Severity Score of 16 or higher. Overall mortality by propensity matching was not different between cohorts (15.6% ALS vs. 15.0% PT, p = 0.82). In severely injured patients (Injury Severity Score ≥16), mortality did not differ between PT and ALS transport (38.8% vs. 36.0%, respectively; p = 0.68). Cox regression analysis controlled for relevant factors revealed no association with a mortality benefit in patients transported by ALS. CONCLUSION: Police transport of penetrating trauma patients in urban locations results in similar outcomes compared with ALS. Immediate transport to definitive trauma care should be emphasized in this patient population. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

A core outcome set for damage control laparotomy via modified Delphi method.

OBJECTIVES: Damage control laparotomy (DCL) remains an important tool in the trauma surgeon's armamentarium. Inconsistency in reporting standards have hindered careful scrutiny of DCL outcomes. We sought to develop a core outcome set (COS) for DCL clinical studies to facilitate future pooling of data via meta-analysis and Bayesian statistics while minimizing reporting bias. METHODS: A modified Delphi study was performed using DCL content experts identified through Eastern Association for the Surgery of Trauma (EAST) 'landmark' DCL papers and EAST ad hoc COS task force consensus. RESULTS: Of 28 content experts identified, 20 (71%) participated in round 1, 20/20 (100%) in round 2, and 19/20 (95%) in round 3. Round 1 identified 36 potential COS. Round 2 achieved consensus on 10 core outcomes: mortality, 30-day mortality, fascial closure, days to fascial closure, abdominal complications, major complications requiring reoperation or unplanned re-exploration following closure, gastrointestinal anastomotic leak, secondary intra-abdominal sepsis (including anastomotic leak), enterocutaneous fistula, and 12-month functional outcome. Despite feedback provided between rounds, round 3 achieved no further consensus. CONCLUSIONS: Through an electronic survey-based consensus method, content experts agreed on a core outcome set for damage control laparotomy, which is recommended for future trials in DCL clinical research. Further work is necessary to delineate specific tools and methods for measuring specific outcomes. LEVEL OF EVIDENCE: V, criteria.

Occupational vs. non-occupational equestrians: Differences in demographics and injury patterns.

INTRODUCTION: Nineteen million people participate in horseback riding activities in the US, and the horse industry employs more than 460,000 full-time workers. Emergency department data suggest young female amateurs and male professionals are most at risk of death from horse-related injuries. However, there has been no investigation into factors that may increase severe injury and mortality risk in these populations. This study investigates demographics and injury pattern differences between occupational and non-occupational horse-related injuries in the US. METHODS: The 2017 American College of Surgeons National Trauma Databank (ACS NTDB) was analyzed for horse-related injury using ICD 10 codes. Demographics, injury data, protective device use, and hospital procedures were analyzed. Occupational versus non-occupational injuries based on incident location (farm, sports, recreational, residential) were compared using ANOVA or Pearson's Chi-squared test. RESULTS: Of 3911 incidents, the most common injury mechanism was falling from the horse, but occupational and non-occupational farm injuries showed higher incidence of being struck by a horse. One-third required surgery. Upper extremity injuries were most common. Occupational injuries more often affected upper extremities of working age, minority males with commercial insurance. Non-occupational injuries most often affected heads of women at the extremes of age. Helmet use was higher in occupational, non-occupational sports, and non-occupational recreation injuries, and severe head injury incidence was decreased in these groups. Complications and discharge dispositions were not different across groups. CONCLUSIONS: In the largest trauma center study to date, we have shown equine-related trauma to be common and affect a predictable demographic that may permit injury prevention initiatives. Helmets may reduce severe head injury, but the efficacy of protective clothing remains to be validated.

Pre-Referral Microbiology in Long Bone Infection: What Can It Tell Us?

Background: It remains unclear how accurately patients' previous microbiology correlates with that ascertained from deep sampling in long bone infection. This study assessed the quality of microbiology referral information and compared it to the gold standard of intra-operative deep tissue sampling. Methods: All patients referred to a single specialist centre within the UK between January 2019 and March 2020 who received surgery for long bone infection were eligible for inclusion. Data on microbiological testing that was performed prior to referral was collected prospectively at the time of clinic appointment and prior to surgery. Pre-referral microbiology was compared to microbiology from deep tissue samples taken during surgery. Results: 141 patients met the diagnostic criteria for long bone infection and were included for analysis. Of these, 72 patients had microbiological information available at referral from 88 samples, obtained from either sinus swab (n = 40), previous surgical sampling (n = 25), biopsy (n = 19) or blood cultures (n = 4). In 65.9% of samples, pre-referral microbiology was deemed to be a non-match when compared to intra-operative samples. Factors that increased risk of a non-match included presence of a sinus (odd's ratio (OR) 11.3 [95% CI 2.84−56.6], p = 0.001), increased duration of time from sampling (OR 2.29, [95% CI 1.23−5.90], p = 0.030) and results from prior surgical sampling (OR 23.0 [95% CI 2.80−525.6], p = 0.011). Furthermore, previous surgical debridement gave an increased risk of multi-, extensively or pan-resistant isolates cultured from intra-operative sampling (OR 3.6 [95% CI 1.5−8.7], p < 0.01). Conclusions: We have demonstrated that presence of a sinus, a long time from the sample being taken and results from prior surgical sampling are more likely to give inaccurate representation of current microbiology. Importantly, in cases with previous debridement surgery, there was an increased risk of multi drug resistant isolates which should be planned for in future treatments.

Demonstration of a U.S. nationwide reduction in transfusion in general surgery and a review of published transfusion reduction methodologies.

BACKGROUND: Red blood cell transfusions in surgical procedures can be lifesaving. However, recent studies show transfusions are associated with a dose-dependent increase in postoperative morbidity and mortality; hospitals and physicians have attempted to reduce them. We sought to determine the success of these efforts and review and summarize published reduction methods employed. STUDY DESIGN/METHODS: An analysis of transfusion data from ACS-NSQIP public use files of general surgical procedures for 2012 and 2018; a retrospective review of the literature surrounding general surgical transfusion reduction from 2008 to 2018. RESULTS: The rate of general surgical transfusion in the NSQIP dataset decreased from 5.5% in 2012 to 4.0% in 2018, a 27% relative reduction in transfusion. After extensive multivariable adjustment for patient risk and operative complexity, this effect remained (Odds ratio 0.65, 95% CI 0.63-0.67, p < .001). Furthermore, there was a positive correlation between specific procedure decreases in transfusion and decreases in 30-day morbidity (rho =0.41, p = .003) and mortality (rho = 0.37, p = .007). There were 866 published studies matching our search term "red blood cell transfusion reduction." Forty-four were relevant to general surgery. Seven dominant strategies for transfusion reduction by descending frequency of report included restrictive transfusion thresholds, management of preoperative anemia, perioperative interventions, educational programs, electronic clinical decision support, waste reduction, and audits of transfusion practices. CONCLUSION: Our study demonstrates a 27% decrease in general surgery transfusion between 2012 and 2018 with associated reductions in morbidity and mortality, suggesting published employed strategies have been successful and safely implemented.

High Resource Utilization in Emergent Versus Elective General Surgery.

BACKGROUND: In an era of pay for performance metrics, we sought to increase understanding of factors driving high resource utilization (HRU) in emergent (EGS) versus same-day elective (SDGS) general surgery patients. METHODS: General surgery procedures from the 2016 ACS-NSQIP public use file were grouped according to the first four digits of the primary procedure CPT code. Groups having at least 100 of both elective and emergent cases were included (22 groups; 83,872 cases). HRU patients were defined as those in-hospital >7D, returned to the OR, readmitted, and/or had morbidity likely requiring an intensive care unit (ICU)stay. Independent NSQIP predictors of HRU were identified through forward regression; P for entry < 0.05, for exit > 0.10. RESULTS: Of all patients, 33% were HRU. The three highest HRU procedures (total colectomy, enterolysis, and ileostomy) comprised a higher proportion of EGS than SDGS cases (10.3 versus 2.6%, P < 0.001). The duration of operation was 40 Min lower in EGS after adjustment. Thirty-nine of the remaining 40 HRU predictors were higher in EGS including preoperative SIRS/Sepsis (50 versus 2%), ASA classification IV-V (31 versus 5%), albumin <3.5 g/dL (40 versus 12%), transfers (26 versus 2%, P's < 0.001), septuagenarians (35 versus 25%) and disseminated cancer (6.3 versus 4.8%, P's < 0.001); while sex did not differ. After adjustment, EGS patients remained more likely to be HRU (odds ratio 2.5, 95% CI 2.4 - 2.6, P < 0.001). CONCLUSIONS: EGS patients utilize significantly more resources than SDGS patients above what can be adjusted for in the clinically robust ACS-NSQIP dataset. Distinctive payment and value-based performance models are necessary for EGS.

The Influence of the Opioid Epidemic on Firearm Violence in Kentucky Counties.

BACKGROUND: The opioid crisis is a major public health emergency. Current data likely underestimate the full impact on mortality due to limitations in reporting and toxicology screening. We explored the relationship between opioid overdose and firearm-associated emergency department visits (ODED & FAED, respectively). METHODS: For the years 2010 to 2017, we analyzed county-level ODED and FAED visits in Kentucky using Office of Health Policy and US Census Bureau data. Firearm death certificate data were analyzed along with high-dose prescriptions from the Kentucky All Schedule Prescription Electronic Reporting records. Socioeconomic variables analyzed included health insurance coverage, race, median household earnings, unemployment rate, and high-school graduation rate. RESULTS: ODED and FAED visits were correlated (Rho = 0.29, P< 0.01) and both increased over the study period, remarkably so after 2013 (P < 0.001). FAED visits were higher in rural compared to metro counties (P < 0.001), while ODED visits were not. In multivariable analysis, FAED visits were associated with ODED visits (Std. B = 0.24, P= 0.001), high-dose prescriptions (0.21, P = 0.008), rural status (0.19, P = 0.012), percentage white race (-0.28, P = 0.012), and percentage high school graduates (-0.68, P < 0.001). Unemployment and earnings were bivariate correlates with FAED visits (Rho = 0.42, P < 0.001 and -0.32, P < 0.001, respectively) but were not significant in the multivariable model. CONCLUSIONS: In addition to recognized nonfatal consequences of the opioid crisis, firearm violence appears to be a corollary impact, particularly in rural counties. Firearm injury prevention efforts should consider the contribution of opioid use and abuse.

An Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Prehospital procedures (PHP) by emergency medical services (EMS) are performed regularly in penetrating trauma patients despite previous studies demonstrating no benefit. We sought to examine the influence of PHPs on outcomes in penetrating trauma patients in urban locations where transport to trauma center is not prolonged. We hypothesized that patients without PHPs would have better outcomes than those undergoing PHP. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored, multicenter, prospective, observational trial of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. The impact of PHPs and transport mechanism on in-hospital mortality were examined. RESULTS: Of 2,284 patients included, 1,386 (60.7%) underwent PHP. The patients were primarily Black (n = 1,527, 66.9%) males (n = 1,986, 87.5%) injured by gunshot wound (n = 1,510, 66.0%) with 34.1% (n = 726) having New Injury Severity Score of ≥16. A total of 1,427 patients (62.5%) were transported by Advanced Life Support EMS, 17.2% (n = 392) by private vehicle, 13.7% (n = 312) by police, and 6.7% (n = 153) by Basic Life Support EMS. Of the PHP patients, 69.1% received PHP on scene, 59.9% received PHP in route, and 29.0% received PHP both on scene and in route. Initial scene vitals differed between groups, but initial emergency department vitals did not. Receipt of ≥1 PHP increased mortality odds (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.01-1.83; p = 0.04). Logistic regression showed increased mortality with each PHP, whether on scene or during transport. Subset analysis of specific PHP revealed that intubation (OR, 10.76; 95% CI, 4.02-28.78; p < 0.001), C-spine immobilization (OR, 5.80; 95% CI, 1.85-18.26; p < 0.01), and pleural decompression (OR, 3.70; 95% CI, 1.33-10.28; p = 0.01) had the highest odds of mortality after adjusting for multiple variables. CONCLUSION: Prehospital procedures in penetrating trauma patients impart no survival advantage and may be harmful in urban settings, even when performed during transport. Therefore, PHP should be forgone in lieu of immediate transport to improve patient outcomes. LEVEL OF EVIDENCE: Prognostic, level III.
