RESUMO
INTRODUCTION: The Traumatic Brain Injury - Patient Reported Outcome (TBI-PRO) model was previously derived to predict long-term patient satisfaction as assessed by the Quality of Life After Brain Injury (QOLIBRI) score. The aim of this study is to externally and prospectively validate the TBI-PRO model to predict long-term patient-reported outcomes and to derive a new model using a larger dataset of older adults with TBI. METHODS: Patients admitted to a Level I trauma center with TBI were prospectively followed for 1 y after injury. Outcomes predicted by the TBI-PRO model based on admission findings were compared to actual QOLIBRI scores reported by patients at 3,6, and 12 mo. When deriving a new model, Collaborative European NeuroTrauma Effectiveness Research in TBI and the Transforming Research and Clinical Knowledge in Traumatic Brain Injury databases were used to identify older adults (≥50 y) with TBI from 2014 to 2018. Bayesian additive regression trees were used to identify predictive admission covariates. The coefficient of determination was used to identify the fitness of the model. RESULTS: For prospective validation, a total of 140 patients were assessed at 3 mo, with follow-up from 69 patients at 6 mo and 13 patients at 12 mo postinjury. The area under receiver operating curve of the TBI-PRO model for predicting favorable outcomes at 3, 6, and 12 mo were 0.65, 0.57, and 0.62, respectively. When attempting to derive a novel predictive model, a total of 1521 patients (80%) was used in the derivation dataset while 384 (20%) were used in the validation dataset. A past medical history of heart conditions, initial hospital length of stay, admission systolic blood pressure, age, number of reactive pupils on admission, and the need for craniectomy were most predictive of long-term QOLIBRI-Overall Scale. The coefficient of determination for the validation model including only the most predictive variables were 0.28, 0.19, and 0.27 at 3, 6, and 12 mo, respectively. CONCLUSIONS: In the present study, the prospective validation of a previously derived TBI-PRO model failed to accurately predict a long-term patient reported outcome measures in TBI. Additionally, the derivation of a novel model in older adults using a larger database showed poor accuracy in predicting long-term health-related quality of life. This study demonstrates limitations to current targeted approaches in TBI care. This study provides a framework for future studies and more targeted datasets looking to assess long-term quality of life based upon early hospital variables and can serve as a starting point for future predictive analysis.
RESUMO
BACKGROUND: Cure Violence interruption programs are evidence-based interventions aimed at reducing the transmission of gun violence and its related injuries. Assessing the implementation of these programs can include the metric of "reach." This study evaluated one such program - 414LIFE - in Milwaukee, Wisconsin. The evaluation reconceptualized "reach" as a metric for reaching the individuals and neighborhoods at greatest risk for gun violence. METHODS: 414LIFE's reach was analyzed descriptively and geospatially through its program evaluation dataset from May 2019 through September 2020 using a cross-sectional design. Program referral criteria includes patients who sustained a gunshot wound, are less than 36 years old, and a resident of, or injured in, the city of Milwaukee. A choropleth map visualized location of participants' residence, which justified a global Moran's I, and then a local Moran's I calculation to identify statistically significant clustering of referrals. RESULTS: In the first 1.5 years of the program's partnership with the local level I trauma center and affiliated academic medical institution, 398 patients were referred. Three hundred referrals (75.4%) met program criteria; 53.8% were Black men. Statistically significant clusters were identified and mapped. Half of the top 10 neighborhoods with referrals were the city's identified priority neighborhoods. CONCLUSIONS: 414LIFE successfully reaches its intended population and geographic locations. Geospatial reach should be considered routinely in program evaluations of Cure Violence programs to track growth and reach over time.

BACKGROUND: Traumatic hemothorax (HTX) is often managed with tube thoracostomy (TT); however, TT carries a high complication rate. In 2017, a guideline was implemented at our Level I trauma center to observe traumatic HTX ≤300mL in hemodynamically stable patients. We hypothesized that this guideline would decrease TT placement without increasing observation failure rates. METHODS: This was a single-center retrospective review of all adult patients admitted with a HTX on computed tomography (CT) before (2015-2016) and after (2018-2019) the guideline implementation. Exclusion criteria were TT placement prior to CT scan, absence of CT scan, death within 5 days of admission, and a concurrent pneumothorax (PTX) >20mm. HTX volume was calculated using CT scan images and Mergo's formula: V=d 2xL (V: volume; d: depth; L: length). The primary outcome was observation failure, defined as the need for TT, video-assisted thoracoscopic surgery, thoracotomy after repeat imaging or worsening of symptoms and pulmonary morbidity. RESULTS: A total of 357 patients met inclusion criteria, of whom 210 were admitted after guideline implementation. There were no significant differences in baseline demographics, comorbidities, or injury characteristics across both cohorts. The post-implementation cohort had a significant increase in observation rate (75% vs 59%) and a decrease in TT placement (42% vs 57%). Moreover, the post-implementation group had a statistically significant shorter hospital (6 vs 8 days) and ICU (2 vs 3 days) LOS. No significant differences in observation failure, pulmonary complications, 30-day readmission, or 30-day mortality were observed across both cohorts. CONCLUSION: The implementation of the 300mL guideline led to a decrease in TT placement without increasing observation failure or complication rates. LEVEL OF EVIDENCE: Level III, Therapeutic/Care Management.
RESUMO
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.
RESUMO
BACKGROUND: Blunt traumatic abdominal wall hernias (TAWHs) are rare but require a variety of operative techniques to repair including bone anchor fixation (BAF) when tissue tears off bony structures. This study aimed to provide a descriptive analysis of BAF technique for blunt TAWH repair. Bone anchor fixation and no BAF repairs were compared, hypothesizing increased hernia recurrence with BAF repair. METHODS: A secondary analysis of the WTA blunt TAWH multicenter study was performed including all patients who underwent repair of their TAWH. Patients with BAF were compared to those with no BAF with bivariate analyses. RESULTS: 176 patients underwent repair of their TAWH with 41 (23.3%) undergoing BAF. 26 (63.4%) patients had tissue fixed to bone, with 7 of those reinforced with mesh. The remaining 15 (36.6%) patients had bridging mesh anchored to bone. The BAF group had a similar age, sex, body mass index, and injury severity score compared to the no BAF group. The time to repair (1 vs 1 days, P = .158), rate of hernia recurrence (9.8% vs 12.7%, P = .786), and surgical site infection (SSI) (12.5% vs 15.6%, P = .823) were all similar between cohorts. CONCLUSIONS: This largest series to date found nearly one-quarter of TAWH repairs required BAF. Bone anchor fixation repairs had a similar rate of hernia recurrence and SSI compared to no BAF repairs, suggesting this is a reasonable option for repair of TAWH. However, future prospective studies are needed to compare specific BAF techniques and evaluate long-term outcomes including patient-centered outcomes such as pain and quality of life.

BACKGROUND: Retained hemothorax (rHTX) requiring intervention occurs in up to 20% of patients who undergo chest tube (TT) placement for a hemothorax (HTX). Thoracic irrigation at the time of TT placement decreases the need for secondary intervention in this patient group but those findings are limited because of the single center design. A multi-center study was conducted to evaluate the effectiveness of thoracic irrigation. METHODS: A multi-center, prospective, observational study was conducted between June 2018 and July 2023. Eleven sites contributed patients. Patients were included if they had a TT placed for a HTX and were excluded if: age < 18 years, TT for pneumothorax, thoracotomy or VATS performed within 6 hours of TT, TT >24 hours after injury, TT removed <24 hours, or death within 48 hours. Thoracic irrigation was performed at the discretion of the attending. Each hemithorax was considered separately if bilateral HTX. The primary outcome was secondary intervention for HTX-related complications (rHTX, effusion, or empyema). Secondary intervention was defined as: TT placement, instillation of thrombolytics, VATS, or thoracotomy. Irrigated and non-irrigated hemithoraces were compared using a propensity weighted analysis with age, sex, mechanism of injury, Abbreviated Injury Scale (AIS) chest and TT size as predictors. RESULTS: 493 patients with 462 treated hemothoraces were included, 123 (25%) had thoracic irrigation at TT placement. There were no significant demographic differences between the cohorts. Fifty-seven secondary interventions were performed, 10 (8%) and 47 (13%) in the irrigated and non-irrigated groups, respectively (p = 0.015). Propensity weighted analysis demonstrated a reduction in secondary interventions in the irrigated cohort (Odds Ratio 0.56 (0.34-0.85); p = 0.005). CONCLUSION: This Western Trauma Association multi-center study demonstrates a benefit of thoracic irrigation at the time of TT placement for a HTX. Thoracic irrigation reduces the odds of a secondary intervention for rHTX-related complications by 44%. LEVEL OF EVIDENCE: Therapeutic Study, Level II.
RESUMO
Genetic manipulation of animal models is a fundamental research tool in biology and medicine but is challenging in large animals. In rodents, models can be readily developed by knocking out genes in embryonic stem cells or by knocking down genes through in vivo delivery of nucleic acids. Swine are a preferred animal model for studying the cardiovascular and immune systems, but there are limited strategies for genetic manipulation. Lipid nanoparticles (LNPs) efficiently deliver small interfering RNA (siRNA) to knock down circulating proteins, but swine are sensitive to LNP-induced complement activation-related pseudoallergy (CARPA). We hypothesized that appropriately administering optimized siRNA-LNPs could knock down circulating levels of plasminogen, a blood protein synthesized in the liver. siRNA-LNPs against plasminogen (siPLG) reduced plasma plasminogen protein and hepatic plasminogen mRNA levels to below 5% of baseline values. Functional assays showed that reducing plasminogen levels modulated systemic blood coagulation. Clinical signs of CARPA were not observed, and occasional mild and transient hepatotoxicity was present in siPLG-treated animals at 5 h post-infusion, which returned to baseline by 7 days. These findings advance siRNA-LNPs in swine models, enabling genetic engineering of blood and hepatic proteins, which can likely expand to proteins in other tissues in the future.
RESUMO
BACKGROUND: Delays in initiating venous thromboembolism (VTE) prophylaxis in patients suffering from traumatic brain injury (TBI) persist despite guidelines recommending early initiation. We hypothesized that the expansion of a Trauma Program Performance Improvement (PI) team will improve compliance of early (24-48 hours) initiation of VTE prophylaxis and will decrease VTE events in TBI patients. METHODS: We performed a single-center retrospective review of all TBI patients admitted to a Level I trauma center before (2015-2016,) and after (2019-2020,) the expansion of the Trauma Performance Improvement and Patient Safety (PIPS) team and the creation of trauma process and outcome dashboards. Exclusion criteria included discharge or death within 48 hours of admission, expanding intracranial hemorrhage on CT scan, and a neurosurgical intervention (craniotomy, pressure monitor, or drains) prior to chemoprophylaxis initiation. RESULTS: A total of 1,112 patients met the inclusion criteria, of which 54% (n = 604) were admitted after Trauma PIPS expansion. Following the addition of a dedicated PIPS nurse in the trauma program and creation of process dashboards, the time from stable CT to VTE prophylaxis initiation decreased (52 hours to 35 hours; p < 0.001) and more patients received chemoprophylaxis at 24 hours to 48 hours (59% from 36%, p < 0.001) after stable head CT. There was no significant difference in time from first head CT to stable CT (9 vs. 9 hours; p = 0.15). The Contemporary group had a lower rate of VTE events (1% vs. 4%; p < 0.001) with no increase in bleeding events (2% vs. 2%; p = 0.97). On multivariable analysis, being in the Early cohort was an independent predictor of VTE events (adjusted odds ratio, 3.74; 95% confidence interval, 1.45-6.16). CONCLUSION: A collaborative multidisciplinary Trauma PIPS team improves guideline compliance. Initiation of VTE chemoprophylaxis within 24 hours to 48 hours of stable head CT is safe and effective. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

INTRODUCTION: Retained hemothorax (HTX) is a common complication following thoracic trauma. Small studies demonstrate the benefit of thoracic cavity irrigation at the time of tube thoracostomy (TT) for the prevention of retained HTX. We sought to assess the effectiveness of chest irrigation in preventing retained HTX leading to a secondary surgical intervention. METHODS: We performed a single-center retrospective study from 2017 to 2021 at a Level I trauma center, comparing bedside thoracic cavity irrigation via TT versus no irrigation. Using the trauma registry, patients with traumatic HTX were identified. Exclusion criteria were TT placement at an outside hospital, no TT within 24 hours of admission, thoracotomy or video-assisted thoracoscopic surgery (VATS) prior to or within 6 hours after TT placement, VATS as part of rib fixation or diaphragmatic repair, and death within 96 hours of admission. Bivariate and multivariable analyses were conducted. RESULTS: A total of 370 patients met the inclusion criteria, of whom 225 (61%) were irrigated. Patients who were irrigated were more likely to suffer a penetrating injury (41% vs. 30%, p = 0.03) and less likely to have a flail chest (10% vs. 21%, p = 0.01). On bivariate analysis, irrigation was associated with lower rates of VATS (6% vs. 19%, p < 0.001) and retained HTX (10% vs. 21%, p < 0.001). The irrigated cohort had a shorter TT duration (4 vs. 6 days, p < 0.001) and hospital length of stay (7 vs. 9 days, p = 0.04). On multivariable analysis, thoracic cavity irrigation had lower odds of VATS (adjusted odds ratio, 0.37; 95% confidence interval [CI], 0.30-0.54), retained HTX (adjusted odds ratio, 0.42; 95% CI, 0.25-0.74), and a shorter TT duration ( ß = -1.58; 95% CI, -2.52 to -0.75). CONCLUSION: Our 5-year experience with thoracic irrigation confirms findings from smaller studies that irrigation prevents retained HTX and decreases the need for surgical intervention. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

BACKGROUND: Traumatic rib fracture is associated with a high morbidity rate and identifying patients at risk of developing pulmonary complications (PC) can guide management and potentially decrease unnecessary intensive care admissions. Therefore, we sought to assess and compare the utility of a physiologic parameter, vital capacity (VC), with the admission radiologic findings (RibScore) in predicting PC in patients with rib fractures. METHODS: This is a single-center retrospective review (2015-2018) of all adult (≥18 years) patients admitted to a Level I trauma center with traumatic rib fracture. Exclusion criteria included no CT scan and absence of VC within 48 h of admission. The cohort was stratified into two groups based on presence or absence of PC (pneumonia, unplanned intubation, unplanned transfer to the intensive care unit for a respiratory concern, or the need for a tracheostomy). Multivariable logistic regression models were constructed to identify predictors of PC. RESULTS: A total of 654 patients met the inclusion criteria of whom 70 % were males. The median age was 51 years and fall (48 %) was the most common type of injury. A total of 36 patients (5.5 %) developed a pulmonary complication. These patients were more likely to be older, had a higher ISS, and were more likely to require a tube thoracostomy placement. On multivariable logistic regression, first VC ≤30 % (AOR: 4.29), day 1 VC ≤30 % (AOR: 3.61), day 2 VC ≤30 % (AOR: 5.54), Δ(Day2-Day1 VC) (AOR: 0.96), and RibScore ≥2 (AOR: 3.19) were significantly associated with PC. On discrimination analysis, day 2 VC had the highest area under the receiver operating characteristic curve (AuROC), 0.81, and was superior to first VC and day 1 VC in predicting PC. There was no statistically significant difference in predicting PC between day 2 VC and RibScore. On multivariable analysis, first VC ≤30 %, day 1 VC ≤30 %, day 2 VC ≤30 %, and admission RibScore ≥2 were associated with prolonged hospital and ICU LOS. CONCLUSION: VC and RibScore emerged as independent predictors of PC. However, VC was not found to be superior to RibScore in predicting PC. Further prospective research is warranted to validate the findings of this study.

BACKGROUND: Non-aortic arterial injuries are common and are associated with high morbidity and mortality. Historically, open surgical repair (OSR) was the conventional method of repair. With recent advancements in minimally invasive techniques, endovascular repair (ER) has gained popularity. We sought to compare outcomes in patients undergoing endovascular and open repairs of traumatic non-aortic penetrating arterial injuries. METHODS: A systematic review and meta-analysis was conducted using MEDLINE (OVID), Web of Science, Cochrane Library, and Scopus Database from January 1st, 1990, to March 20th, 2023. Titles and abstracts were screened, followed by full text review. Articles assessing clinically important outcomes between OSR and ER in penetrating arterial injuries were included. Exclusion criteria included blunt injuries, aortic injuries, pediatric populations, review articles, and non-English articles. Odds ratios (OR) and Cohen's d ratios were used to quantify differences in morbidity and mortality. RESULTS: A total of 3770 articles were identified, of which 8 met inclusion criteria and were included in the review. The articles comprised a total of 8369 patients of whom 90 % were male with a median age of 28 years. 85 % of patients were treated with OSR while 15 % underwent ER. With regards to injury characteristics, those who underwent ER were less likely to present with concurrent venous injuries (OR: 0.41; 95 %CI: 0.18, 0.94; p = 0.03). Regarding hospital outcomes, patients who underwent ER had a lower likelihood of in-hospital or 30-day mortality (OR: 0.72; 95 %CI: 0.55, 0.95; p = 0.02) and compartment syndrome (OR: 0.29, 95 %CI: 0.12, 0.71; p = 0.007). The overall risk of bias was moderate. CONCLUSION: Endovascular repair of non-aortic penetrating arterial injuries is increasingly common, however open repair remains the most common approach. Compared to ER, OSR was associated with higher odds of compartment syndrome and mortality. Further prospective research is warranted to determine the patient populations and injury patterns that most significantly benefit from an endovascular approach.

BACKGROUND: Traumatic brain injury patients who require neurosurgical intervention are at the highest risk of worsening intracranial hemorrhage. This subgroup of patients has frequently been excluded from prior research regarding the timing of venous thromboembolism chemoprophylaxis. This study aims to assess the efficacy and safety of early venous thromboembolism chemoprophylaxis in patients with traumatic brain injuries requiring neurosurgical interventions. METHODS: This is a single-center retrospective review (2016-2020) of traumatic brain injury patients requiring neurosurgical intervention admitted to a level I trauma center. Interventions included intracranial pressure monitoring, subdural drain, external ventricular drain, craniotomy, and craniectomy. Exclusion criteria included neurosurgical intervention after chemoprophylaxis initiation, death within 5 days of admission, and absence of chemoprophylaxis. The total population was stratified into Early (≤72 hours of intervention) versus Late (>72 hours after intervention) chemoprophylaxis initiation. RESULTS: A total of 351 patients met the inclusion criteria, of whom 204 (58%) had early chemoprophylaxis initiation. Overall, there were no significant differences in baseline and admission characteristics between cohorts. The Early chemoprophylaxis cohort had a statistically significant lower venous thromboembolism rate (5% vs 13%, P < .001) with no increased risk of worsening intracranial hemorrhage (10% vs 13%, P = .44) or neurosurgical reintervention (8% vs 10%, P = .7). On subgroup analysis, a total of 169 patients required either a craniotomy or a craniectomy before chemoprophylaxis. The Early chemoprophylaxis cohort had statistically significant lower venous thromboembolism rates (2% vs 11%, P < .001) with no increase in intracranial hemorrhage (8% vs 11%, P = .6) or repeat neurosurgical intervention (8% vs 10%, P = .77). CONCLUSION: Venous thromboembolism prophylaxis initiation within 72 hours of neurosurgical intervention is safe and effective. Further prospective research is warranted to validate the results of this study.

BACKGROUND: Blunt traumatic abdominal wall hernias (TAWH) occur in <1 % of trauma patients. Optimal repair techniques, such as mesh reinforcement, have not been studied in detail. We hypothesize that mesh use will be associated with increased surgical site infections (SSI) and not improve hernia recurrence. MATERIALS AND METHODS: A secondary analysis of the Western Trauma Association blunt TAWH multicenter study was performed. Patients who underwent TAWH repair during initial hospitalization (1/2012-12/2018) were included. Mesh repair patients were compared to primary repair patients (non-mesh). A logistic regression was conducted to assess risk factors for SSI. RESULTS: 157 patients underwent TAWH repair during index hospitalization with 51 (32.5 %) having mesh repair: 24 (45.3 %) synthetic and 29 (54.7 %) biologic. Mesh patients were more commonly smokers (43.1 % vs. 22.9 %, p = 0.016) and had a larger defect size (10 vs. 6 cm, p = 0.003). Mesh patients had a higher rate of SSI (25.5 % vs. 9.5 %, p = 0.016) compared to non-mesh patients, but a similar rate of recurrence (13.7 % vs. 10.5%, p = 0.742), hospital length of stay (LOS), and mortality. Mesh use (OR 3.66) and higher ISS (OR 1.06) were significant risk factors for SSI in a multivariable model. CONCLUSION: Mesh was used more frequently in flank TAWH and those with a larger defect size. Mesh use was associated with a higher incidence and risk of SSI but did not reduce the risk of hernia recurrence. When repairing TAWH mesh should be employed judiciously, and prospective randomized studies are needed to identify clear indications for mesh use in TAWH.

BACKGROUND: Diaphragmatic hernia (DH) presenting acutely can be a potentially life-threatening condition. Its management continues to be debatable. METHODS: A bibliographic search using major databases was performed using the terms "emergency surgery" "diaphragmatic hernia," "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia." GRADE methodology was used to evaluate the evidence and give recommendations. RESULTS: CT scan of the chest and abdomen is the diagnostic gold standard to evaluate complicated DH. Appropriate preoperative assessment and prompt surgical intervention are important for a clinical success. Complicated DH repair is best performed via the use of biological and bioabsorbable meshes which have proven to reduce recurrence. The laparoscopic approach is the preferred technique in hemodynamically stable patients without significant comorbidities because it facilitates early diagnosis of small diaphragmatic injuries from traumatic wounds in the thoraco-abdominal area and reduces postoperative complications. Open surgery should be reserved for situations when skills and equipment for laparoscopy are not available, where exploratory laparotomy is needed, or if the patient is hemodynamically unstable. Damage Control Surgery is an option in the management of critical and unstable patients. CONCLUSIONS: Complicated diaphragmatic hernia is a rare life-threatening condition. CT scan of the chest and abdomen is the gold standard for diagnosing the diaphragmatic hernia. Laparoscopic repair is the best treatment option for stable patients with complicated diaphragmatic hernias. Open repair is considered necessary in majority of unstable patients in whom Damage Control Surgery can be life-saving.

BACKGROUND: Understanding the expectations of early career acute care surgeons will help clarify the practice and employment models that will attract and retain high-quality surgeons, thereby sustaining our workforce. This study aimed to outline the clinical and academic preferences and priorities of early career acute care surgeons and to better define full-time employment. METHODS: A survey on clinical responsibilities, employment preferences, work priorities, and compensation was distributed to early career acute care surgeons in the first 5 years of practice. A subset of agreeable respondents underwent virtual semistructured interviews. Both quantitative and thematic analysis were used to describe current responsibilities, expectations, and perspectives. RESULTS: Of 471 surgeons, 167 responded (35%), the majority of whom were assistant professors within the first 3 years of practice (80%). The median desired clinical volume was 24 clinical weeks and 48 call shifts per year, 4 weeks less than their median current clinical volume. Most respondents (61%) preferred a service-based model. The top priorities cited in choosing a job were geography, work schedule, and compensation. Qualitative interviews identified themes related to defining full-time employment, first job expectations and realities, and the often-misaligned system and surgeon. CONCLUSION: Understanding the perspectives of early career surgeons entering the workforce is important particularly in the field of acute care surgery where no standard workload or practice model exists. The wide variety of expectations, practice models, and schedule preferences may lead to a mismatch between surgeon desires and employment expectation. Consistent employment standards across our specialty would provide a framework for sustainability. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.
