The objective assessment of technical skills of junior residents is essential in implementing competency-based training and providing specific feedback regarding areas for improvement. An innovative assessment that can be easily implemented by training programs nationwide has been developed by expert surgeon educators under the aegis of the American College of Surgeons (ACS) Division of Education. This assessment, ACS Objective Assessment of Skills in Surgery (ACS OASIS) uses eight stations to address technical skills important for junior residents within the domains of laparoscopic appendectomy, excision of lipoma, central line placement, laparoscopic cholecystectomy, trocar placement, exploratory laparotomy, repair of enterotomy, and tube thoracostomy. The purpose of this study was to implement ACS OASIS at a number of sites to study its psychometric rigor.The ACS OASIS was pre-piloted at two programs to establish feasibility and to gather information regarding implementation. Each skills station was 12 minutes long, and the faculty completed a checklist with 5 to 15 items, and a global assessment scale. The study was then repeated at three pilot sites and included 29 junior residents who were assessed by a total of 44 faculty. Psychometric data for the stations and checklists were collected and analyzed.The pre-pilot sites were Geisinger and University of Tennessee Knoxville.Data were gathered from pilot sites that included Wellspan Health, Duke University, and University of California Los Angeles.The mean checklist score for all learners was 76% (IQR of 66%-85%). The average global rating was 3.36 on a 5-point scale with a standard deviation of 0.56. The overall cut score derived using the borderline group method was at 68% with 34% of performances requiring remediation. Using this criterion, the average number of stations that were completed by each learner without need for remediation was five.The station discrimination index ranged from 0.27 to 0.65 (all above the threshold of 0.25), demonstrating solid psychometric characteristics at the station level. The internal-consistency reliability was 0.76 with SEM of 5.8%. The inter-rater reliability (intraclass correlation) was high at 0.73 with general agreement of 79% between the two raters. The station discrimination was at 0.45 (range of 0.27 to 0.65) indicating a high level of differentiation between high and low performers. Using the generalizability theory, the G-coefficient reliability was at 0.72 with the reliability projection flattening after 8 stations. Overall, 75% to 82% the faculty and learners rated ACS OASIS as realistic and beneficial.ACS OASIS is a psychometrically sound technical skills assessment tool that can provide useful information for feedback to junior residents and support efforts to remediate gaps in performance.

We sought to characterize if prehospital transfer origin from the scene of injury (SCENE) or from a referral emergency department (REF) alters the survival benefit attributable to prehospital plasma resuscitation in patients at risk of hemorrhagic shock.We performed a secondary analysis of data from a recently completed prehospital plasma clinical trial. All of the enrolled patients from either the SCENE or REF groups were included. The demographics, injury characteristics, shock severity and resuscitation needs were compared. The primary outcome was a 30-day mortality. Kaplan-Meier analysis and Cox-hazard regression were used to characterize the independent survival benefits of prehospital plasma for transport origin groups.Of the 501 enrolled patients, the REF group patients (n = 111) accounted for 22% with the remaining (n = 390) originating from the scene. The SCENE group patients had higher injury severity and were more likely intubated prehospital. The REF group patients had longer prehospital times and received greater prehospital crystalloid and blood products. Kaplan-Meier analysis revealed a significant 30-day survival benefit associated with prehospital plasma in the SCENE group (P.01) with no difference found in the REF group patients (P = .36). The Cox-regression verified after controlling for relevant confounders that prehospital plasma was independently associated with a 30-day survival in the SCENE group patients (hazard ratio 0.59; 95% confidence interval 0.39-0.89; P = .01) with no significant relationship found in the REF group patients (hazard ratio 1.03, 95% confidence interval 0.4-3.0).Important differences across the SCENE and REF cohorts exist that are essential to understand when planning prehospital studies. Prehospital plasma is associated with a survival benefit primarily in SCENE group patients. The results are exploratory but suggest transfer origin may be an important determinant of prehospital plasma benefit.

Background Rib fracture (RF) pain management provides analgesia while reducing opioids. We postulated: (1) Prescriber factors affect opiate duration, and (2) lidocaine infusion curtails dependency. Materials and Methods Retrospective study of RF patients undergoing multimodal analgesia at ACS-verified Level 1 Trauma Center April 2018-February 2020. Exclusions: ageResults 153 patients included – 113 (74%) stopped opiates by 30 days post-discharge (NORx30), 40 (26%) continued beyond 30 days (Rx+). No significant differences in age, gender, ISS, number of RF, bilaterality, flail chest, and discharge disposition. Significant differences included hospital LOS (7.62 NORx30 vs. 10.22 Rx+, p = .02), number of prescribers (1.73 NORx30 vs. 2.98 Rx+, p < .01), average MME/day during initial 30 days post-discharge (36.7 ± 17 NORx30 vs. 45.4 ± 30.2 Rx+, p = .03), and number of pills (49 ± 38 NORx30 vs. 120 ± 85 Rx+, p < .01). Patients who received lidocaine infusion (LIDO+) had lower MME/day prescribed (32.24 ± 19.9, p = .03), were younger (61.2 vs. 65.6, p < .01), had more RFs (7.1 vs. 6.05, p = .03), and shorter LOS (7.71 vs 10.2, p = .01). Discussion Prescriber attention to MME/day and number of pills dispensed affects opioid dependency. We recommend 35–40 MME/day with 50 pill/month limit prescribed by a single provider monitoring patient and CSMD. Early LI offers post-discharge opioid cessation advantage.

Emotional intelligence (EI) is associated with job success in multiple fields, in part, because EI may mitigate stress and burnout. Research suggests these relationships may include teaching. Our purpose is to further explore the relationships between EI, burnout, and teaching for faculty surgeons.With IRB approval, surgical faculty were offered the opportunity to complete personal demographics, the Maslach Burnout Inventory, the SETQ-SMART assessment of teaching ability, and the SEF:MED self-assessment of emotional intelligence. Surgical residents rated faculty teaching ability using the SETQ-SMART SETTING: A medium-sized academic medical center in the Southeast approved to graduate 6 residents per year.ACGME surgical faculty and general surgical residents PGY1 to PGY5 including preliminary residents, were given the opportunity to participate.Faculty self-assessed teaching scores were significantly different from resident scores for nine (60%) faculty; three (33%) overrated their and 6 (67%) under rated their overall teaching ability, relative to resident ratings. The 3 SEF:MED scales correlated low-moderate to strongly with the SETQ-OTS: IS (r = 0.41, p = 0.13), EM (r = 0.67, p0.01), and EA (r = 0.43, p = 0.11). Overall, 8(53%) faculty scored moderate to high on at least 1 of the 3 MBI subscales. Overall self-rated faculty teaching scores correlated negatively with higher EE and DP and positively with PA (r = -0.08, -0.21, and 0.52, p = 0.047; respectively). EI negatively correlated with MBI-EE and DP and positively with PA (r = -0.31, -0.18, 0.45, respectively), though due to the small sample none reach statistical significance with alpha set to 0.05.In this pilot study, EI is positively correlated to surgical faculty members' teaching ability. Burnout was less strongly correlated with resident-assessed faculty teaching scores, but with similar trends. Finally, EI was correlated with MBI EE, DP, and PA as expected given the literature in other fields. Expanded study is warranted.

The authors sought to identify causal factors that explain the selective benefit of prehospital administration of thawed plasma (TP) in traumatic brain injury (TBI) patients using mediation analysis of a multiomic database.The Prehospital Air Medical Plasma (PAMPer) Trial showed that patients with TBI and a pronounced systemic response to injury [defined as endotype 2 (E2)], have a survival benefit from prehospital administration of TP. An interrogation of high dimensional proteomics, lipidomics and metabolomics previously demonstrated unique patterns in circulating biomarkers in patients receiving prehospital TP, suggesting that a deeper analysis could reveal causal features specific to TBI patients.A novel proteomic database (SomaLogic Inc., aptamer-based assay, 7K platform) was generated using admission blood samples from a subset of patients (n=149) from the PAMPer Trial. This proteomic dataset was combined with previously reported metabolomic and lipidomic datasets from these same patients. A 2-step analysis was performed to identify factors that promote survival in E2-TBI patients who had received early TP. First, features were selected using both linear and multivariate-latent-factor regression analyses. Then, the selected features were entered into the causal mediation analysis.Causal mediation analysis of observable features identified 16 proteins and 41 lipids with a high proportion of mediated effect (50%) to explain the survival benefit of early TP in E2-TBI patients. The multivariate latent-factor regression analyses also uncovered 5 latent clusters of features with a proportion effect30%, many in common with the observable features. Among the observable and latent features were protease inhibitors known to inhibit activated protein C and block fibrinolysis (SERPINA5 and CPB2), a clotting factor (factor XI), as well as proteins involved in lipid transport and metabolism (APOE3 and sPLA(2)-XIIA).These findings suggest that severely injured patients with TBI process exogenous plasma differently than those without TBI. The beneficial effects of early TP in E2-TBI patients may be the result of improved blood clotting and the effect of brain protective factors independent of coagulation.

Objectives Hypothermia occurs in 30-50% of severely injured trauma patients and is associated with multiple metabolic derangements and worsened outcomes. However, hypothermia continues to be under-diagnosed which leads to inadequate triage and treatment in trauma patients. Our study set out to determine if hypothermia is an independent predictor of mortality in trauma patients. Methods We retrospectively reviewed data of all trauma activation patients over a 5-year period. Data were collected on patient demographics, initial core temperature, Glasgow Coma Scale (GCS) on presentation, and injury severity score (ISS). Patients were then stratified into groups based on presenting temperature, ISS, and GCS. Outcomes compared were mortality, blood products received, and intensive care unit (ICU) length of stay. Correlations and logistic regression were used to test the hypotheses. Results Survival and temperature data were reviewed on 15,567 patients. Initial temperature was not significantly associated with ICU length of stay or blood products transfused ( P = .21 and P = .08, respectively). However, odds ratio of mortality in hypothermic patients (Conclusions Hypothermia is an independent risk factor for mortality in trauma patients. It remains crucial to obtain accurate presenting temperatures in trauma patients in order to triage and treat hypothermia. Based on our data, obtaining core temperatures and rapidly treating hypothermia continues to be a vital part of the secondary survey of trauma patients.

Background Multimodal analgesia in rib fractures (RFs) is designed to maximize pain control while minimizing narcotics. Prior research with intravenous lidocaine (IVL) efficacy produced conflicting results. We hypothesized IVL infusion reduces opioid utilization and pain scores. Methods A retrospective review of RF patients at an ACS-verified Level I trauma center from April 2018 to 2/2020 was conducted. Patients (pts) stratified as receiving IVL vs no IVL. Initial lidocaine dose: 1 mg/kg/hr with a maximum of 3 mg/kg/hr. Duration of infusion: 48 h. Pain quantified by the Stanford Pain Score system (PS). Bivariate and multivariate analyses of variables were performed on SPSS, version 21 (IBM Corp). Results 414 pts met inclusion criteria: 254 males and 160 females. The average age for the non-IVL = 67.4 ± 15.2 years vs IVL = 58.3 ± 17.1 years ( P < .001). There were no statistically significant differences between groups for ISS, PS for initial 48 h, and ICU length of stay (LOS). There was a difference in morphine equivalents per hour: non-IVL = 1.25 vs IVL = 1.72 ( P = .004) and LOS non-IVL = 10.2+/−7.6 vs IVL = 7.82+/−4.94. By analyzing IVL pts in a crossover comparison before and after IVL, there was reduction in opiates: 3.01 vs 1.72 ( P < .001) and PS: 7.0 vs 4.9 ( P < .001). Stanford Pain Score system reduction in the IVL = 48.3 ± 23.9%, but less effective in narcotic dependency (27 ± 22.9%, P = .035); IVL pts had hospital cost reduction: $82,927 vs $118,202 ( P < .01). Discussion In a crossover analysis, IVL is effective for reduction of PS and opiate use and reduces hospital LOS and costs. Patient age may confound interpretation of results. Our data support IVL use in multimodal pain regimens. Future prospective study is warranted.

Summary Trauma is a leading cause of death and morbidity worldwide. Here, we present the analysis of a longitudinal multi-omic dataset comprising clinical, cytokine, endotheliopathy biomarker, lipidome, metabolome, and proteome data from severely injured humans. A “systemic storm” pattern with release of 1,061 markers, together with a pattern suggestive of the “massive consumption” of 892 constitutive circulating markers, is identified in the acute phase post-trauma. Data integration reveals two human injury response endotypes, which align with clinical trajectory. Prehospital thawed plasma rescues only endotype 2 patients with traumatic brain injury (30-day mortality: 30.3 versus 75.0%; p = 0.0015). Ubiquitin carboxy-terminal hydrolase L1 (UCHL1) was identified as the most predictive circulating biomarker to identify endotype 2-traumatic brain injury (TBI) patients. These response patterns refine the paradigm for human injury, while the datasets provide a resource for the study of critical illness, trauma, and human stress responses., Graphical abstract, Highlights An integrated longitudinal multi-omic analysis of the human response to trauma Systemic storm and massive consumption patterns are related to early mortality Unique resolution and non-resolution signatures across multiple “omics” platforms Only endotype 2-TBI patients with high UCHL1 levels benefit from early plasma, Wu et al. report a longitudinal multi-omic analysis of the circulation in trauma patients. Cross-platform data integration reveals a massive systemic release of cellular contents (“systemic storm”) and simultaneous consumption of blood constituents. Also defined are patient endotypes that differ in outcomes and responses to early plasma administration.
