Surgery Morbidity and Mortality (MM) presentations include a thorough literature review. This requires a significant amount of time expenditure frequently incompatible with the current surgical resident work hours. Additionally, literature reviews can be redundant for commonly encountered adverse events. The goal of this study was to explore (a) how surgery residents perform literature reviews, and (b) how repetitive presented adverse events are.A survey was sent out during the academic year 2019-2020. The Morbidity and Mortality repository for that academic year was indexed, and the proportion of adverse events having occurred more than once calculated. The amount of time spent on literature reviews, proportion of repetitive adverse events as well as degree of thoroughness of reviews was evaluated on a 1 to 5 Likert scale.Tulane University General Surgery program, New Orleans, LA, USA.All clinically active residents.All residents, filled out the survey. Seventeen out of 29 (58.6%) residents reported dedicating approximately one hour performing literature reviews. Median studying time was 1 hour (interquartile range: 1-1.5 hours). Seventeen out of 29 (58.6%) residents employed 2 resources. The most common combination of resources was PubMed and Google (11/29, 37.9%). Most residents (21/29, 72.4%) believed that their thoroughness was at most average (≤3/5 on a Likert scale) and 27/29 (93.1%) believed that their literature review could have been more thorough. More than half of the adverse events presented were found to be redundant during that academic year.Time spent reviewing the literature does not allow for a thorough review, and a significant portion of adverse events presented are redundant. A central repository for literature reviews of adverse events would improve the quality of reviews and avoid duplicating efforts.

BACKGROUND Despite the liver being one of the most frequently injured abdominal organs in trauma patients, clinical management strategies differ between trauma surgeons. Few studies have critically evaluated current practice patterns in the operative management of liver trauma. Historical studies recommended against the use of drains but there has not been a modern investigation of this issue. The objective of this study was to analyze outcomes associated with intra-operative drain use for liver trauma. METHODS A retrospective chart review of all adult trauma patients presenting to a Level I trauma center from 2012 to 2018 was performed. Patients who underwent operative management of liver trauma were divided into groups based on whether an intra-abdominal drain was utilized and differences in outcomes between the groups were analyzed. The primary endpoint evaluated was post-operative intra-abdominal abscesses. Univariate and multivariate analyses were performed. RESULTS 184 patients with operative management of liver trauma were included in the study. Closed suction drains were utilized in 26.1% of post-operative patients. Rate of intra-abdominal abscesses was significantly higher in the drain group (35.4% versus 8.8%, P < 0.001). Drains were more commonly used in patients receiving more units of PRBCs (median, 9 units [IQR 4-20] versus median 5.5 units, [IQR 2-14], P = 0.03). Drain use was found to be an independent risk factor for post-operative intra-abdominal abscess on multivariate analysis (OR 4.9, 95% CI 1.7-14, P = 0.003). CONCLUSIONS The results of this study support previous conclusions that drain placement for operative liver trauma is associated with increased risks of infectious complications. Drains were used in patients with more severe liver injury, intra-operative bile leaks, penetrating trauma, and increased blood transfusion requirements. Future studies should focus on the development of specific guidelines for the use of drains in liver trauma.

Trauma scores are used to give clinicians appropriate quantitative context in making decisions. Studies show that anatomical trauma scores predicted intensive care unit admission better, while physiological trauma scores predicted mortality better. We hypothesize that trauma scores have a hierarchy of efficacies at predicting mortality and operative decision making.We performed a retrospective analysis of our trauma patient database at a level 1 trauma center from 2016 to 2020 and calculated the following trauma scores: Glasgow Coma Scale, Revised Trauma Score, Trauma Injury Severity Score, Injury Severity Score, Shock Index, and New Trauma Injury Severity Score (NISS). Receiver operating characteristic curves were used to evaluate the sensitivity and specificity of trauma scores for predicting mortality.A total of 738 patients were included (mean ± SD age, 35.7 ± 15.6 years). Area under the curve (AUC) results from the DeLong test showed that NISS predicted mortality the best compared with other trauma scores. New Trauma Injury Severity Score was superior in predicting mortality for penetrating trauma (AUC, 0.86 ± 0.02; p0.001) compared with blunt trauma (AUC, 0.73 ± 0.04; p0.001). Trauma Injury Severity Score was the best predictor of mortality for patients with gunshot wounds (AUC, 0.83; 95% confidence interval [CI], 0.73-0.92; p0.001), motor vehicle accidents (AUC, 0.80; 95% CI, 0.61-1.00; p = 0.01), and falls (AUC, 0.73; 95% CI, 0.61-0.85; p = 0.007).New Trauma Injury Severity Score was the best scoring index for predicting mortality in trauma patients, especially for penetrating trauma. Clinicians should consider incorporating other trauma scores, especially NISS and Trauma Injury Severity Score, in determining injury severity and the likelihood of mortality. These scores can help physicians determine the best course of action in patient management.Prognostic and Epidemiologic; level IV.

PURPOSE Surgical site infections (SSI) are a significant source of peri-operative morbidity and a financial burden on the healthcare system. Effective pre-operative skin preparation has been shown to reduce SSI incidence, however studies demonstrated that most healthcare providers do not adhere to proper techniques. Skin prep technique is not taught to U.S. surgical residents in a standardized format. The objective of this study was to perform a survey of U.S. surgical training programs to determine the practice patterns of surgical resident education on the proper techniques of pre-operative antiseptic surgical prep. METHODS An 18-question anonymous survey was created using the Qualtrics platform. The survey was distributed to members of the Association of Program Directors in Surgery listserv over a 2-month period. Responses were compiled and data analysis was performed. RESULTS The survey response rate was 30% (n = 85/280). 81% of respondents reported that surgery residents are responsible for performing pre-operative skin prep at their institutions. The same proportion (81%) reported that they feel surgical skin prep techniques are an important component of surgical resident education. However, only 42% reported that their residents are provided formal education regarding proper skin prep techniques and only 6% reported that their residents are required to take a written or practical proficiency exam. 42% of respondents felt that formal skin prep education for residents is likely to affect the rate of surgical site infections. CONCLUSIONS Surgical residents commonly perform pre-operative skin preparation. However, few residents receive formal education or evaluation of these skills. Given the importance of pre-operative skin preparation in reducing SSIs and the potential for patient harm if performed incorrectly, the results from this study raise the question of whether formal surgical resident education regarding pre-op skin prep should be more widely adopted and standardized.

Principles of damage control laparotomy (DCL) focus on early surgical control of hemorrhage and contamination in addition to damage control resuscitation (DCR) to combat the significant mortality associated with the "death triad" of hypothermia, acidosis, and coagulopathy. We hypothesized that DCL patients managed with DCR would have lower mortality from the death triad than historical studies.A 5-y retrospective chart review of all consecutive adult trauma patients presenting to a Level I trauma center who underwent DCL was conducted. Parameters associated with the death triad were evaluated on admission and 24 h after the presentation. Kaplan Meier survival plots were used to compare the components of the death triad. Univariate and multivariate analyses were performed.A total of 149 adult patients were identified. The overall incidence of death triad was 20.8% (n = 31/149). 24-h mortality for all patients was 5.4% (n = 8/149). Kaplan Meier plots showed that 24-h mortality was significantly increased if 3/3 components of the death triad were present (P 0.05). At 24-h after admission, mortality occurred in 16.6% (n = 5/30) of patients with the death triad.This study confirms that the 24-h mortality of trauma patients increased with the addition of all three death triad components. The death triad predicted death in 16.6% of patients treated with DCL and DCR at 24 h. Results suggest that the death triad might not be as applicable in the modern era of DCL in combination with DCR. Other factors contributing to in-hospital mortality need to be further elucidated.

Background Pediatric pelvic fractures are a significant source of morbidity for children in the United States. In the era of specialized care, the relationship between trauma center designation and outcomes remains unknown. We hypothesized that there would be no difference in patient outcomes when treated at adult trauma centers (ATCs), pediatric trauma centers (PTCs), or dual trauma centers (DTCs). Materials and methods We used the National Trauma Data Bank to identify pediatric (≤14 y) patients suffering pelvic fractures in 2013-2015. DTCs were defined as centers with level I or II trauma designation for both pediatric and adult care. Primary outcomes included mortality, complications, and computed tomography (CT) utilization. Results There were 4260 patients who met study criteria. Of these, 1290 (22%) were treated at ATCs, 1332 (30%) at PTCs, and 2120 (48%) at DTCs. Pediatric patients treated at ATCs were more likely to suffer a complication or receive a CT scan. On multivariate analysis, patients treated at PTCs and DTCs were significantly less likely to have a recorded complication or receive head, thoracic, or whole-body CT scans compared with ATCs. DTCs, but not PTCs, used fewer abdominal CT scans. Mortality rates were not predicted by center designation. Conclusions For pediatric pelvic fractures, centers with pediatric trauma designation (PTCs and DTCs) appear to have better outcomes despite significantly less use of CT scans. Further studies are needed to determine optimal management of pediatric pelvic fractures while minimizing exposure to ionizing radiation. Level of evidence Level III Retrospective.

The coronavirus disease 2019 (COVID-19) pandemic is a slow-moving global disaster with unique challenges for maintaining trauma center operations. University Medical Center New Orleans is the only level 1 trauma center in New Orleans, LA, which became an early hotspot for COVID-19. Intensive care unit surge capacity, addressing components including space, staff, stuff, and structure, is important in maintaining trauma center operability during a high resource-strain event like a pandemic. We report management of the trauma center’s surge capacity to maintain trauma center operations while assisting in the care of critically ill COVID-19 patients. Lessons learned and recommendations are provided to assist trauma centers in planning for the influx of COVID-19 patients at their centers.

The association of procedure volume and improved outcomes has been established with infrequently performed elective operations. However, effect of trauma center volume on outcomes in emergency surgery has not been defined. We hypothesized that high volume centers (HVC) would provide better outcomes for operative major vascular injuries (MVI) than low volume centers (LVC).The NTDB was queried from 2010 to 2014. Patients with MVI were identified and HVC were compared to LVC. HVC were defined as480 patients per year with ISS≥15.There were 37,125 patients with MVI, with 16,461 (44.3%) managed operatively. Of these, 15,965 (97%) underwent surgery at HVC and 496 (3%) at LVC. There was no difference in shunt utilization, however, HVC were more likely to utilize endovascular repair (31.0% vs. 21.9%, p 0.001). Rates of death, amputation, and compartment syndrome were similar. HVC were more likely to develop pneumonia or sepsis. On logistic regression, HVC was not associated with survival (OR: 0.90, 95%CI: 0.60-1.34, p = 0.60). Variables associated with mortality for HVC and LVC included thoracic arterial injury (OR: 1.57, 95%CI: 1.27-1.94, p 0.001), penetrating mechanism (OR:1.84, 95%CI: 1.57-2.15, p 0.001), and open repair (OR: 1.95, 95%CI: 1.69-2.26, p 0.001). Lower ISS (OR: 0.29, 95%CI: 0.24-0.34, p 0.001) and higher presenting blood pressure (OR: 0.99, 95%CI: 0.99-1.00, p 0.001) were associated with survival.Although LVC may have less proficiency with endovascular techniques, trauma center volume does not influence survival in emergency surgery for MVI.

Background Penetrating neck trauma continues to present a diagnostic dilemma. Practice guidelines advocate the use of computed tomography angiography (CTA) for suspected vascular or aero-digestive injuries in all neck zones. There is also an evolving evidence of 'No Zone' approach where the decision to obtain a CTA is guided by physical exam findings and clinical presentation. The aim of this systematic review is to examine existing literature on the diagnostic accuracy of CTA as an integral component of the "no zone" approach in stable patients witt penetrating neck trauma. Methods We performed a systematic review using an electronic search of three databases (PubMed, Medline, Cochrane Review) from 2000-2017. Results A total of 5 prospective and 8 retrospective studies were included. The sensitivity of CTA ranged from 83-100%; specificity, 61-100%; positive predictive value, 30-100% and negative predictive value, 90-100%. Three studies reported high sensitivity and specificity for the detection of vascular injuries, but low specificity for aero-digestive tract injuries. When stratified by clinical presentation, CTA had a sensitivity of 89.5-100% and specificity of 61-100% in stable patients presenting with soft signs. In a combined group of stable patients with either hard signs or soft signs, the sensitivity of CTA was 94.4-100% and specificity 96.7-100%. Among patients presenting with hard signs, the sensitivity of CTA was 78.6-90% and specificity is 100%. Conclusions This is the first systematic review to examine the role of computed tomography angiography in penetrating neck trauma. In combination with physical exam, CTA demonstrated a reliable high sensitivity and specificity for detecting injuries in penetrating neck trauma in stable patients with soft signs of injury and select patients with hard signs of injury. These results support the management of penetrating neck trauma using "no zone" approach based on physical examination and the use of CTA in stable patients.

Background Burnout affects surgical residents’ well-being. Objective We sought to identify factors associated with burnout among surgery residents. Methods An electronic/anonymous survey was sent to surgical residents at 18 programs, consisting of demographic/programmatic questions and validated scales for burnout, depression, perceived stress, self-efficacy, and social support. Residents were grouped into quartiles based off burnout, and predictors were assessed using univariate and multivariate analyses. Results 42% of residents surveyed completed it. Burnout was associated with depression, higher perceived stress/debt, fewer weekends off, less programmatic social events, and residents were less likely to reconsider surgery if given the chance. Low burnout was associated with lower depression/stress, higher social support/self-efficacy, more weekends off per month, program mentorship, lower debt, and residents being more likely to choose surgery again if given the chance. On multivariate analysis, higher depression/perceived stress were associated with burnout, and lower burnout scores were associated with lower stress/higher self-efficacy. Conclusions Burnout in surgery residents is associated with higher levels of depression and perceived stress. The addition of programmatic social events, limiting weekend work, and formal mentoring programs may decrease burnout.

Background Alcohol-related motor vehicle collisions (AR-MVCs) account for ~30% of all US traffic fatalities. Ride-sharing services (RSS) have existed since 2010, but few studies to date have investigated their impact on AR-MVCs. We hypothesized that the availability of RSS would be correlated with a decrease in AR-MVCs at an urban Level I trauma center. Methods A retrospective chart review was conducted of all AR-MVC trauma activations at a Level I trauma center from 2012 to 2018. Additional data were gathered from regional governmental traffic and law enforcement databases, including crash incidence, fatalities, and demographics. Data were compared pre- and post-RSS and analyzed using an unpaired t test with p less than 0.05 considered significant. Results There were 1,474 patients in AR-MVCs during the study period. There was a significant decrease in the annual average proportion of MVCs that were AR-MVCs pre- vs. post-RSS (39% vs. 29%, p = 0.02) as well as a decrease in the average annual incidence of fatal AR-MVCs (11.6 vs. 5, p = 0.02). Subset analysis showed a decrease in AR-MVC incidence in 18- to 29-year-olds (12.7% vs. 7.5%; p = 0.03), which was also demonstrated by data from a local law enforcement database. Availability of RSS was also correlated with a decreased proportion of nighttime AR-MVCs (14.7% vs. 7.6%, p = 0.03) and decreased number of driving while intoxicated (1198.0 ± 78.5 vs. 612.8 ± 137.6, p = Conclusion We found that the incidence of both total AR-MVCs and fatal AR-MVCs presenting to our trauma center decreased after the introduction of RSS. Ride-sharing services may play a role in preventing AR-MVCs. Further research is needed to correlate AR-MVC incidence with granular proprietary RSS usage data and to account for any confounding factors. Future studies may identify ways to better utilize RSS availability as a targeted intervention for certain demographic groups to prevent AR-MVCs.

To describe the first year of the Educational Quality Improvement Program (EQIP) DESIGN: The Educational Quality Improvement Program (EQIP) was formed by the Association of Program Directors in Surgery (APDS) in 2018 as a continuous educational quality improvement program. Over 18 months, thirteen discrete goals for the establishment of EQIP were refined and executed through a collaborative effort involving leaders in surgical education. Alpha and beta pilots were conducted to refine the data queries and collection processes. A highly-secure, doubly-deidentified database was created for the ingestion of resident and program data.36 surgical training programs with 1264 trainees and 1500 faculty members were included in the dataset. 51,516 ERAS applications to programs were also included. Uni- and multi-variable analysis was then conducted.EQIP was successfully deployed within the timeline described in 2020. Data from the ACGME, ABS, and ERAS were merged with manually entered data by programs and successfully ingested into the EQIP database. Interactive dashboards have been constructed for use by programs to compare to the national cohort. Risk-adjusted multivariable analysis suggests that increased time in a technical skills lab was associated with increased success on the ABS's Qualifying Examination, alone. Increased time in a technical skills lab and the presence of a formal teaching curriculum were associated with increased success on both the ABS's Qualifying and Certifying Examination. Program type may be of some consequence in predicting success on the Qualifying Examination.The APDS has proved the concept that a highly secure database for the purpose of continuous risk-adjusted quality improvement in surgical education can be successfully deployed. EQIP will continue to improve and hopes to include an increasing number of programs as the barriers to participation are overcome.

With increased social isolation due to COVID-19, social media has been increasingly adopted for communication, education, and entertainment. We sought to understand the frequency and characteristics of social media usage among general surgery trainees.General surgery trainees in 15 American training programs were invited to participate in an anonymous electronic survey. The survey included questions about demographics, frequency of social media usage, and perceptions of risks and benefits of social media. Univariate analysis was performed to identify differences between high users of social media (4-7 h per week on at least one platform) and low users (0-3 h or less on all platforms).One hundred fifty-seven of 591 (26.6%) trainees completed the survey. Most respondents were PGY3 or lower (75%) and high users of social media (74.5%). Among high users, the most popular platforms were Instagram (85.7%), YouTube (85.1%), and Facebook (83.6%). YouTube and Twitter were popular for surgical education (77.3% and 68.2%, respectively). The most reported benefits of social media were improving patient education and professional networking (85.0%), where high users agreed more strongly about these benefits (P = 0.002). The most reported risks were seeing other residents (42%) or attendings (17%) with unprofessional behavior. High users disagreed more strongly about risks, including observing attendings with unprofessional behavior (P = 0.028).Most respondents were high users of social media, particularly Instagram, YouTube, and Facebook. High users incorporated social media into their surgical education while perceiving more benefits and fewer risks of social media.

Trauma patients receiving massive transfusion protocol (MTP) are at risk of citrate-induced hypocalcemia and hyperkalemia. Here we evaluate potassium (K), ionized calcium (iCa), and K/iCa ratio as predictors of mortality.This retrospective study includes all adult trauma patients who received MTP within 1 h at our level I trauma center between 2014 and 2019. Receiver operating characteristic curve analysis assessed predictive accuracy of K/iCa ratio at admission on 120-day mortality.Of 614 patients, 146 received MTP within 1 h and 38 expired. Patients who expired had higher K/iCa ratio than survivors (median [IQR] = 5.7 [3.8-7.2] vs 3.7 [3.1-4.9], p 0.001). Area under the curve of K/iCa was 0.72 (95%CI = 0.62-0.82, p 0.001) with sensitivity = 63.2% and specificity = 77.6%. At the optimum K/iCa cutoff (5.07), patients with high ratios had 4 times higher mortality risk (HR = 3.97, 95%CI = 1.89-8.32, p 0.001).Elevated K/iCa ratio was an independent predictor of mortality in trauma patients managed with MTP.

Bystanders play a significant role in the immediate management of life-threatening hemorrhage. The Stop the Bleed (STB) program was designed to train lay rescuers (LRs) to identify and control life-threatening bleeding. The aim of this study was to evaluate the efficacy of STB training for rescuers from different backgrounds. We hypothesized that STB training would be appropriate to increase skills and knowledge of bleeding control techniques for all providers, regardless of level of medical training.Course participants anonymously self-reported confidence in six major areas. A five-point Likert scale was used to quantitate participant's self-reported performance. Results were stratified into medical rescuers (MR) and LRs. Students' ability to perform STB skills were objectively assessed using an internally validated 15-point objective assessment tool. Data were pooled and analyzed using Student's t-test and chi-Squared test with P 0.05 considered significant. Results are presented as average with standard deviation (SD) unless otherwise stated.A total of 1974 participants were included in the study. Precourse confidence was lowest for both groups in management of active severe bleeding and ability to pack a bleeding wound. Postcourse confidence improved significantly for both groups in all 6 core areas measured (P 0.001). The most significant increases were reported in the two previous areas of lowest precourse confidence-management of active severe bleeding-LRs 2.0 (SD 1.2) versus 4.2 (SD 0.9) and MRs 2.6 (SD 1.4) versus 4.6 (SD 0.6), P 0.001-and ability to pack a bleeding wound-LR 2.1 (SD 1.3) versus 4.4 (SD 0.8) and MR 2.7 (SD 1.3) versus 4.7 (SD 0.05), P 0.001. Objective assessment of LR skills at the end of the course demonstrated combined 99.3% proficiency on postcourse objective assessments.This study provides quantitative evidence that Stop the Bleed training is effective, with both LRs and MRs demonstrating improved confidence and skill proficiency after a 1-h course. Future program development should focus on building a pool of instructors, continued training of LRs, and determining how often skills should be recertified.

Failure to rescue (FTR), defined as death after a major complication in surgical patients, is being used to measure outcomes for quality improvement. Major complications frequently occur in patients undergoing damage control laparotomy (DCL). No previous FTR studies have looked specifically into DCL patients. The aim of this study was to examine risk factors of FTR and identify potential areas for targeted quality improvement in DCL patients. A 10-year retrospective review of all consecutive adult trauma patients who underwent DCL at a Level I trauma center was performed. Demographic and clinical variables were examined for association with FTR. Multi-variate regression analysis was performed to identify risk factors of FTR in DCL patients. A total of 199 DCL patients were analyzed. Overall DCL mortality observed was 11.1 per cent (n = 22/199) and overall FTR for the cohort was n = 16/199. FTR represented 72 per cent (n = 16/22) of the total mortality. The significantly increased risk of FTR was associated with older age ( P = 0.027), lower initial Glasgow Coma Scale score ( P = 0.037), more units of packed red blood cells ( P = 0.028), and respiratory complications ( P = 0.035). Renal and infectious complications did not significantly increase the risk of FTR in this population. FTR is an important benchmark of quality for trauma patients. This study elucidates potential initial characteristics and complications related to FTR in DCL patients. Efforts in achieving zero death from FTR can potentially improve overall mortality in this subset of patients. Future quality interventions to help minimize FTR should target these specific areas.

Ventilator-associated pneumonia (VAP) affects up to 30 per cent of ICU patients and has been associated with increased morbidity and mortality. We identified factors associated with prolonged latency of VAP and evaluated its effects on survival and additional outcomes. We also determined the sensitivity of various clinical definitions of VAP, including the Centers for Disease Control and Prevention (CDC) 2013 criteria. We hypothesized that the CDC 2013 criteria would have poor sensitivity. We collected data on 102 subjects who developed VAP between 2012 and 2017. We conducted a Kaplan-Meier survival analysis with Cox proportional hazards regression and generalized linear models/ANOVA to look at predictor variables along with multivariate models for each outcome. White patients, nonsurgical patients, patients with renal failure, altered mental status, increased FiO2, and increased positive end-expiratory pressure had worse survival. Trauma patients, patients with positive sputum cultures, and patients with suspected pneumonia had better survival. Sensitivity of the CDC 2013 criteria was only 44.1 per cent. Our results emphasize the importance of having a high index of suspicion for VAP in ventilator-dependent patients. The 2013 CDC criteria failed to detect 55.9 per cent of confirmed VAP cases. These results are concerning because undetected VAP can have devastating consequences for patients.

BACKGROUND Previous epidemiological studies on pediatric firearm mortality have focused on overall mortality rather than on-scene mortality. Despite advances in trauma care, the number of potentially preventable deaths remains high. This study used the National Emergency Medical Services Information Systems database to characterize patterns of on-scene mortality in order to identify patients who may benefit from changes to prehospital care practices. METHODS National Emergency Medical Services Information Systems database was searched for all pediatric firearm incidents from 2010 to 2015. Data on demographics, anatomic location of injury, intent and location of incident, and on-scene mortality were analyzed using Student's t test for continuous variables and χ test for categorical variables. A linear regression model was used to calculate independent predictors of mortality. RESULTS Sixteen thousand eight hundred eight patients were identified, with a mortality rate of 6.1%. Most mortalities suffered cardiac arrest on-scene; 72.6% of these were prior to Emergency Medical Services (EMS) arrival, which carried a significantly higher mortality rate than arrest after EMS arrival. No difference was seen in anatomic location of injury in those who arrested before and after EMS arrival. Compressible injuries were most common with the lowest mortality. Noncompressible injuries together accounted for 25.8% of injuries and 23.5% of mortalities. CONCLUSION To our knowledge, this is the largest study of on-scene mortality in pediatric firearm injury. Cardiac arrest prior to EMS arrival was a considerable source of on-scene mortality; significantly more of these patients died than those who arrested after EMS arrival. The mortality of compressible injuries was very low, implying that use of compression and tourniquets have been effective in stopping life-threatening extremity bleeding. Noncompressible injury mortality could be decreased with education of bystanders and more aggressive on-scene intervention. Through the evaluation of on-scene mortality specifically, this study offers insight into potential areas of focus to improve prehospital care of pediatric gunshot victims.

BACKGROUND The number of urban bicyclists has grown exponentially across the United States. Bike lanes were created to promote a safe environment for both motorist and cyclists, but few studies have specifically addressed the outcomes of these interventions. The aim of this study was to analyze the effect of bike lanes on bicycle usage and safety in a major urban city. METHODS A retrospective chart review of consecutive adult trauma patients presenting at an urban Level I trauma center due to motor vehicle versus bicycle collisions from January 1, 2007, to January 28, 2017, was performed. Cohorts were stratified into prebicycle and postbicycle lane implementation for analysis. RESULTS Bicycle use during the study period increased almost three fold (1,672 vs. 6,060, p < 0.0001). There was also a spike in the percent of yearly bicyclists as trauma patients during the 10-year period (0.7% vs. 1.5%, p < 0.05). A total of 184 patients brought to the trauma center were identified. Significant differences between the prebike lane and postbike lane groups were identified for average Injury Severity Score (12.7 ± 1.7 vs. 8.0 ± 0.6 p = 0.0134), Glasgow Coma Scale score on arrival (12.6 ± 0.7 vs. 13.9 ± 0.2, p = 0.0171), proportion of head and face injuries (59.4% to 38.8%, p = 0.047), and patients requiring surgical intervention (100% to 55.9%, p < 0.0001). CONCLUSION As bicycle lanes become increasing popular in US cities, it is important to review the success of this intervention on improving safety. Preliminary results from this study suggest that the implementation of urban bike lanes improved bicyclist safety. Further studies should focus on specific injury prevention programs, which could help to target areas such as helmet use and riding a bicycle while impaired to help improve overall safety.

BACKGROUND Numerous advancements in hemorrhage control and volume replacement that comprise damage control resuscitation (DCR) have been implemented in the last decade to reduce deaths from bleeding. We sought to determine the impact of DCR interventions on mortality over 12 years in a massive transfusion protocol (MTP) population. We hypothesized that mortality would be decreased in later years, which would have used more DCR interventions. STUDY DESIGN This was a retrospective review of all MTP patients treated at a large regional Level I trauma center from 2008 to 2019. Interventions by year of implementation examined included MTP 1:1 ratio (2009), liquid plasma (2010), tranexamic acid (2012), prehospital tourniquets (2013), REBOA/TEG (2017), satellite blood station (2018), and whole blood transfusion (2019). Relative risk and odds of mortality for DCR interventions were examined. RESULTS There were 824 MTP patients included. The cohort was primarily male (80.6%) injured by penetrating mechanism (68.1%) with median (interquartile range) age 31 years (23-44) and New Injury Severity Score 25 (16-34). Overall mortality was unchanged [(38.3%-56.6%); P = 0.26]. Tourniquets (P = 0.02) and whole blood (WB) (P = 0.03) were associated with lower unadjusted mortality; only tourniquets remained significant after adjustment (OR: 0.39; 95% CI: 0.17-0.89; P = 0.03). CONCLUSIONS Despite lower mortality with use of tourniquets and WB, mortality rates due to hemorrhage have not improved at our high MTP volume institution, suggesting implementation of new in-hospital strategies is insufficient to reduce mortality. Future efforts should be directed toward moving hemorrhage control and effective resuscitation interventions to the injury scene.

Surgical stabilization for rib fractures (SSRF) in trauma patients remains controversial, with guidelines currently suggesting the procedure for only select patient groups. How surgical stabilization for rib fractures affect hospital readmission in patients with traumatic rib fractures is unknown. We hypothesized that surgical stabilization for rib fractures would not decrease the risk of readmission.The National Readmission Database was examined for adults with any rib fractures from 2010 to 2017. Readmission up to 90 days was examined. Patients receiving surgical stabilization for rib fractures were compared with those receiving nonoperative treatment.In total, 864,485 patients met criteria, with 13,701 (1.6%) receiving SSRF. For patients receiving SSRF, 338 (1.5%) were readmitted. Readmitted patients had higher Charlson Comorbidity Index and were more likely to have flail chest. On multivariate propensity score-matched analysis, SSRF (Hazard Ratio [HR]: 0.55, 95% confidence interval [CI] 0.33-0.92, P = .022) was associated with reduced readmission. Addition of surgical stabilization for rib fractures to video-assisted thoracoscopic surgery (VATS) (Odds Ratio [OR]: 0.95, 95% CI 0.52-1.73, P = .86) or thoracotomy (OR: 1.97, 95% CI 0.83-4.70, P = .13) was not associated with increased readmission. On further propensity matched analysis, VATS + SSRF when compared with SSRF alone (HR: 0.75, 95% CI 0.18-3.20, P = .696), and VATS + SSRF when compared with VATS alone (HR: 0.49, 95% CI 0.11-2.22, P = .355) was also not associated with increased readmission. SSRF on primary admission was associated with increased in-hospital survival (HR: 0.27, 95% CI 0.22-0.32, P.001). For patients with retained hemothorax who underwent VATS, addition of SSRF did not improve survival (HR = 0.92, 95% CI 0.58-1.46, P = .72). However, for patients requiring thoracotomy for retained hemothorax, concomitant SSRF was associated with improved survival (HR = 0.14, 95% CI 0.06-0.32, P.001).Surgical stabilization for rib fractures is associated with reduced readmission risk while also being associated with improved survival. Patients who had a thoracotomy for retained hemothorax appear to especially benefit from concomitant surgical stabilization for rib fractures.

IntroductionPreventable deaths following trauma are high and unchanged over the last two decades. The objective of this study was to describe the location of death in patients with penetrating trauma, stratified by anatomic location of injury, in order to better tailor our approach to reducing preventable deaths from trauma.MethodsThis retrospective analysis of a prospectively maintained trauma registry included consecutive adult trauma activations with penetrating trauma at a level 1 trauma center between 07/2012 and 03/2018. Injuries were categorized as extremity, junctional, and torso. Head and neck injuries were excluded. Patients injured in >1 defined location were categorized as “multiple.” Location of death was defined as on-scene, emergency department (ED), or hospital. Two-sided χ2tests were used to compare groups. Multivariate analysis was performed using logistic regression.ResultsA total of 1024 patients were included with an overall case fatality rate (CFR) of 7.8%. The CFR following extremity injury (3.0%) was significantly lower than all other injury sites ( P = .02).There were no significant differences in CFR for junctional (10.4%), torso (8.3%), or multiple injuries (9.6%). Forty percent of fatalities following junctional injury occurred on-scene and an additional 20% occurred in the ED.DiscussionTo our knowledge, this is the first study to describe location of death stratified by anatomic location of injury. There was no difference in the CFRs of junctional and torso injuries, and a large proportion of deaths occurred prior to reaching the hospital or in the trauma bay. These findings support reevaluating the classical algorithms and care pathways for patients with proximal penetrating trauma.

Background How the surgical stabilization of rib fractures after trauma affects the development of acute respiratory distress syndrome and impacts survival has yet to be determined in a large database. We hypothesized that surgical stabilization of rib fractures would not decrease the incidence of acute respiratory distress syndrome. Methods The National Trauma Data Bank was queried for all traumatic rib fractures in 2016. Patients were divided into groups with single rib fractures, multiple rib fractures, and flail chest. Nonoperative therapy was compared with stabilization of rib fractures of 1 to 2 ribs or 3+ ribs. Results There were 114,972 total patients with rib fractures meeting inclusion criteria, with 5,106 (4.4%) having flail chest, 24,726 (21.5%) having single rib fractures, and 85,140 (74.1%) having multiple rib fractures. Those with flail chest (15.9%) were most likely to get rib plating in comparison to multiple rib fractures (0.9%) and single rib fractures (0.2%); P < .001. On logistic regression, surgical stabilization of rib fractures 1 to 2 ribs (odds ratio: 0.17, 95% confidence interval: 0.10–0.28) or 3+ ribs (odds ratio: 0.17, 95% confidence interval: 0.11–0.28), with nonoperative therapy as the reference was associated with survival. Variables associated with mortality included increasing age, male sex, increasing injury severity score, decreased Glasgow coma scale, requirement of transfusions, and hypotension on admission. Surgical stabilization of rib fractures 3+ ribs (odds ratio: 2.30, 95% confidence interval: 1.58–3.37) was associated with acute respiratory distress syndrome but not 1 to 2 ribs (odd ratio: 1.55, 95% confidence interval: 0.97–2.48). On logistic regression of only patients with flail chest, stabilization of rib fractures was associated with decreased mortality but not increased risk of acute respiratory distress syndrome. Conclusion The increased risk of acute respiratory distress syndrome should be considered in the preoperative assessment for stabilization of rib fractures.

INTRODUCTION Recent studies have suggested the female hypercoaguable state may have a protective effect in trauma. However, whether this hypercoagulable profile confers a survival benefit in massively transfused trauma patients has yet to be determined. We hypothesized that females would have better outcomes than males after traumatic injury that required massive transfusion protocol (MTP). PATIENTS AND METHODS All trauma patients who underwent MTP at an urban, level 1, academic trauma center were reviewed from November 2007 to October 2018. Female MTP patients were compared to their male counterparts. RESULTS There were a total of 643 trauma patients undergoing MTP. Of these, 90 (13.8%) were female and 563 (86.2%) were male. Presenting blood pressure, heart rate, shock index, and injury severity score (ISS) were not significantly different. Overall mortality and incidence of venous thromboembolism were similar. Complication profile and hospital stay were similar. On logistic regression, female sex was not associated with survival (HR: 1.04, 95% CI: 0.56-1.92, P = 0.91). Variables associated with mortality included age (HR: 1.02, 95% CI: 1.05-1.09, P = 0.03) and ISS (HR: 1.07, 95% CI: 1.05-1.09, P

Patient safety and quality improvement (QI) processes are vitally important to healthcare systems. Training and experience in QI processes are mandated by the Accreditation Council for Graduate Medical Education (ACGME) for general surgery residents. The execution and efficacy of these training programs in residencies have thus far been inconsistent. The purpose of this study was to assess the effectiveness of our surgical residency's QI educational program.We instituted a formalized QI educational program for all residents in our academic general surgery residency program from 2018 to 2019. The curriculum included didactics, online educational resources, peer-group collaboration, and faculty mentorship. Residents performed a self-assessment survey of their knowledge, skill, and comfort levels with QI processes before and after the program using a 10-point Likert scale. The number of QI projects conducted, presented, and subsequently prepared for publication was enumerated. The ACGME resident survey program results regarding resident involvement in QI processes before and after program implementation were compared.After 1 year of the program, residents demonstrated significant increases in average self-assessed knowledge of QI processes (6.4 vs. 4.0, p0.05), knowledge of local QI resources (5.4 vs. 3.3, p0.05), and confidence in their ability to develop and implement a QI project (6.3 vs. 3.9, p0.05). The average number of QI projects each resident participated in the year preceding the program vs. during the program increased from 0.4 to 1.8 (p0.05). Ten of 26 residents (38%) reported no direct involvement in a QI project the preceding year before the QI program implementation, while 26/26 (100%) of residents reported direct involvement in at least 1 QI project during the implementation year. Residency program ACGME survey results regarding resident participation in QI increased from 86% (just below the national average of 87%) before the development of the QI program to 97% after program implementation.Implementation of a formalized, structured quality improvement education program for surgery residents significantly increased residents' participation in QI projects, as well as increasing their confidence in their knowledge and skillset to perform QI processes. The residency program's ACGME resident survey results regarding resident involvement in QI also improved during program implementation.

Bicycle injuries continue to cause significant morbidity in the United States. How insurance status affects outcomes in children with bicycle injuries has not been defined. We hypothesized that payer status would not impact injury patterns or outcomes in pediatric bicycle-related accidents.The National Trauma Data Bank was used to identify pediatric (≤18 y) patients involved in bicycle-related crashes admitted in year 2016. Patients with private insurance were compared with all others (uninsured, Medicaid, and Medicare).There were 5619 patients that met study criteria. Of these, 2500 (44%) had private insurance. Privately insured were older (12 y versus 11, P 0.001), more likely to be white (77% versus 56%, P 0.001), and more likely to wear a helmet (26% versus 9%, P 0.001). On multivariate analysis, factors associated with traumatic brain injury included age (odds ratio [OR], 1.07; 95% confidence interval [CI], 1.06-1.08; P 0.001) and helmet use (OR, 0.64; 95% CI, 0.55-0.74; P 0.001). Patients without private insurance were significantly less likely to wear a helmet (OR, 0.52; 95% CI, 0.44-0.63; P 0.001). Uninsured patients had significantly higher odds of a fatal injury (OR, 4.43; 95% CI, 1.52-12.92; P = 0.006).Uninsured children that present to a trauma center after a bicycle accident are more likely to die. Although helmet use reduced the odds of traumatic brain injury, minorities and children without private insurance were less likely to be helmeted. Public health interventions should increase helmet access to children without private insurance, especially uninsured children.

BACKGROUND The Trauma Quality Improvement Project (TQIP) uses an injury prediction model for performance benchmarking. We hypothesize that at a Level I high-volume penetrating trauma center, performance outcomes will be biased due to inclusion of patients with nonsurvivable injuries. METHODS Retrospective chart review was conducted for all patients included in the institutional TQIP analysis from 2013 to 2014 with length of stay (LOS) less than 1 day to determine survivability of the injuries. Observed (O)/expected (E) mortality ratios were calculated before and after exclusion of these patients. Completeness of data reported to TQIP was examined. RESULTS Eight hundred twenty-six patients were reported to TQIP including 119 deaths. Nonsurvivable injuries accounted 90.9% of the deaths in patients with an LOS of 1 day or less. The O/E mortality ratio for all patients was 1.061, and the O/E ratio after excluding all patients with LOS less than 1 day found to have nonsurvivable injuries was 0.895. Data for key variables were missing in 63.3% of patients who died in the emergency department, 50% of those taken to the operating room and 0% of those admitted to the intensive care unit. Charts for patients who died with LOS less than 1 day were significantly more likely than those who lived to be missing crucial. CONCLUSION This study shows TQIP inclusion of patients with nonsurvivable injuries biases outcomes at an urban trauma center. Missing data results in imputation of values, increasing inaccuracy. Further investigation is needed to determine if these findings exist at other institutions, and whether the current TQIP model needs revision to accurately identify and exclude patients with nonsurvivable injuries. Level of Evidence Prognostic and epidemiological, level III.

The benefits of the Affordable Care Act (ACA) for trauma patients have been well established. However, the ACA's impact on penetrating trauma patients (PTPs), a population that is historically young and uninsured, has not been defined. We hypothesized that PTPs in the post-ACA era would have better outcomes.The National Trauma Data Bank (NTDB) was queried for all PTPs from 2009 (pre-ACA) and 2011-2014 (post-ACA). Subset analysis was performed in patients aged 19-25 y, as this group was eligible for the ACA's dependent care provision (DCP).There were 9,714,471 patients in the study, with 2,053,501 (21.1%) pre-ACA and 7,660,970 (78.9%) post-ACA. When compared to pre-ACA, patients in the post-ACA cohort were more likely to have commercial/private insurance, less likely to have Medicaid, and more likely to be uninsured. On logistic regression, the pre-ACA era was associated with mortality (HR: 1.02, 95% CI: 1.01-1.04, P = 0.004). Being uninsured was associated with mortality (HR: 1.89, 95% CI: 1.87-1.92, P 0.001). On subset analysis of the DCP age group, post-ACA patients were more likely to be uninsured (24.1% versus 17.6%; P 0.001). In addition, for the DCP age group, pre-ACA era was not associated with mortality (HR: 1.03, 95% CI: 0.99-1.06, P = 0.20).Although the ACA provided a survival benefit to PTPs overall, it did not increase insurance coverage for this population. In addition, the DCP of the ACA did not improve insurance access for PTP in the eligible age group. Further efforts are needed to extend insurance access to this population.

Background The indications and outcomes associated with temporary intravascular shunting (TIVS) for vascular trauma in the civilian sector are poorly understood. The objective of this study was to perform a contemporary multicenter review of TIVS use and outcomes. Methods Patients sustaining vascular trauma, requiring TIVS insertion (January 2005 to December 2013), were retrospectively identified at seven Level I trauma centers. Clinical demographics, operative details, and outcomes were abstracted. Results A total of 213 injuries (2.7%; 94.8% arterial) requiring TIVS were identified in 7,385 patients with vascular injuries. Median age was 27.0 years (range, 4-89 years), 91.0% were male, Glasgow Coma Scale (GCS) score was 15.0 (interquartile range, 4.0), Injury Severity Score (ISS) was 16.0 (interquartile range, 15.0), 26.0% had an ISS of 25 or greater, and 71.1% had penetrating injuries. The most common mechanism was gunshot wound (62.7%), followed by auto versus pedestrian (11.4%) and motor vehicle collision (6.5%). Shunts were placed for damage control in 63.4%, staged repair for combined orthopedic and vascular injuries in 36.1%, and for insufficient surgeon skill set in 0.5%. The most common vessel shunted was the superficial femoral artery (23.9%), followed by popliteal artery (18.8%) and brachial artery (13.2%). An argyle shunt (81.2%) was the most common conduit, followed by Pruitt-Inahara (9.4%). Dwell time was less than 6 hours in 61.4%, 24 hours in 86.5%, 48 hours in 95.9%, with only 4.1% remaining in place for more than 48 hours. Of the patients, 81.6% survived to definitive repair, and 79.6% survived overall. Complications included shunt thrombosis (5.6%) and dislodgment (1.4%). There was no association between dwell time and shunt thrombosis. The use of a noncommercial shunt (chest tube/feeding tube) did not impact shunt thrombosis but was an independent risk factor for subsequent graft failure. The limb salvage rate was 96.3%. No deaths could be attributed to a shunt complication. Conclusion In the largest civilian TIVS experience insertion to date, both damage control and staged orthopedic vascular injuries were common indications for shunting. With an acceptable complication burden and no associated mortality attributed to this technique, shunting should be considered a viable treatment option.

OBJECTIVE The Stop the Bleed (STB) program trains lay rescuers to identify and control life-threatening bleeding. Recently, medical students were allowed to become coinstructors. The aim of this study was to assess the efficacy of medical student course participation as both learners and instructors. No previous study to date has provided a critical objective assessment of medical student learners and educators of STB courses. STUDY DESIGN Participants anonymously self-reported pre- and postcourse confidence in 6 major skill areas using a 5-point Likert scale. At the end of the course, students’ ability to perform STB skills was assessed using an internally validated 15-point objective assessment tool. SETTING Two US medical schools (Tulane University School of Medicine and Louisiana State University in New Orleans) which represent private and state institutions, respectively. PARTICIPANTS A total of 423 medical students were enrolled in the course. A pilot group of medical students volunteered to be instructors and their ability to effectively teach the course was objectively assessed. RESULTS Overall precourse confidence was highest in holding pressure on a wound and lowest in identification of severe active bleeding. Postcourse participant confidence increased significantly in all 6 core areas, including confidence to teach hemorrhage control skills to others. Objective assessment of medical students by STB instructors found 72.4% of medical students achieving perfect scores on their skill proficiency assessments. An assessment of 48 medical student instructors found that all students were able to proficiently serve as instructors. CONCLUSIONS This study demonstrates that medical students can effectively master STB skills and can also serve as competent course instructors. Future program development should focus on continued training of medical students and their involvement as instructors to help increase the availability of STB courses.

Despite increasing popularity of prehospital tourniquet use in civilians, few studies have evaluated the efficacy and safety of tourniquet use. Furthermore, previous studies in civilian populations have focused on blunt trauma patients. The objective of this study was to determine if prehospital tourniquet use in patients with major penetrating trauma is associated with differences in outcomes compared to a matched control group.An 8-year retrospective analysis of adult patients with penetrating major extremity trauma amenable to tourniquet use (major vascular trauma, traumatic amputation and near-amputation) was performed at a Level I trauma center. Patients with prehospital tourniquet placement (TQ) were identified and compared to a matched group of patients without tourniquets (N-TQ). Univariate analysis was used to compare outcomes in the groups.A total of 204 patients were matched with 127 (62.3%) in the prehospital TQ group. No differences in patient demographics or injury severity existed between the two groups. Average time from tourniquet application to arrival in the emergency department (ED) was 22.5 ± 1.3 minutes. Patients in the TQ group had higher average systolic blood pressure on arrival in the ED (120 ± 2 vs. 112 ± 2, p = 0.003). The TQ group required less total PRBCs (2.0 ± 0.1 vs. 9.3 ± 0.6, p0.001) and FFP (1.4 ± 0.08 vs. 6.2 ± 0.4, p0.001). Tourniquets were not associated with nerve palsy (p = 0.330) or secondary infection (p = 0.43). Fasciotomy was significantly higher in the N-TQ group (12.6% vs. 31.4%, p0.0001) as was limb amputation (0.8% vs. 9.1%, p = 0.005).This study demonstrated that prehospital tourniquets could be safely used to control bleeding in major extremity penetrating trauma with no increased risk of major complications. Prehospital tourniquet use was also associated with increased systolic blood pressure on arrival to the ED, decreased blood product utilization and decreased incidence of limb related complications, which may lead to improved long-term outcomes and increased survival in trauma patients.Therapeutic, level IV.

Objective We hypothesize that students exposed to both academic and community surgery clerkship sites will have higher National Board of Medical Examiners Subject Exam in Surgery (NBME SES) scores and be more likely to pursue a career in a surgical specialty. Design The NBME surgery subject exam scores and National Resident Matching Program (NRMP) results were collected for all medical students rotating through the surgery clerkship over 4 years. Permutations of sites were analyzed against exam scores and match rates into surgical and nonsurgical specialties. Setting This study was performed at the Tulane University School of Medicine, in New Orleans, Louisiana, United States of America. Participants Data for a total of 910 students rotating through the surgery clerkship over a period of 4 years was collected and analyzed. Results There was no statistical difference in NBME subject exam scores (p = 0.44) or match rates into a surgical specialty (p = 0.13) as stratified by site placement. Average NBME surgery subject exam scores were higher for those pursuing a surgical specialty (p Conclusions The combination of sites experienced during the surgery clerkship did not affect NBME surgery subject exam scores nor lead to a tendency to match into a surgical specialty.

There exists a long established but not validated practice of placing temporary intravascular shunts (TIVS) in cases of combined vascular and orthopedic extremity trauma. Though logical to prioritize blood flow, large-scale data to support this practice is lacking. We hypothesize that the order of repair yields no difference in outcomes in combined vascular and orthopedic extremity trauma and offer a larger-scale analysis than is previously available.A retrospective chart review was conducted at six Level I trauma centers from 2004 to 2015 comparing patients who received a TIVS during their initial surgery versus those who did not. Nonshunted patients were further divided into initial definitive vascular repair versus initial orthopedic fixation groups. Metrics were used to control for sampling bias while revision rate, amputation, hospital length of stay (HLOS), and development of thrombosis and compartment syndrome were used to assess outcomes.Of 291 total patients, 72 had TIVS placement, 97 had initial definitive vascular repair, and 122 had initial orthopedic fixation. The shunted group had a higher Abbreviated Injury Scale (3.0 vs. 2.8 p = 0.04) and Mangled Extremity Severity Score (6.1 vs. 5.7 p = 0.006) and a significantly lower rate of compartment syndrome (15% vs. 34% p = 0.002). Among patients who developed compartment syndrome, those who were shunted were younger (23 vs. 35 yrs, p = 0.03) and were more likely sustain a penetrating injury (p = 0.007). Those receiving initial orthopedic fixation had a longer HLOS (HLOS15 days in 61% vs. 38%, p = 0.049) and a higher amputation rate (20% vs. 7%, p = 0.006) when compared with those undergoing initial definitive vascular repair.Lack of TIVS was associated with a significant increase in the development of compartment syndrome. Though it seems to have become common practice to proceed directly to vascular repair during the initial surgery, morbidity is improved with the placement of a TIVS.Therapeutic cohort, level III.
