RESUMEN
OBJECTIVE: With new rules regarding social distancing and non-essential travel bans, we sought to determine if faculty scoring of general surgery applicants would differ between the in-person interview (IPI) and virtual interview (VI) platforms. DESIGN: A single institution, retrospective review comparing faculty evaluation scores of applicant interviewees in the 2019 and 2020 MATCH® application cycles (IPIs) and the 2021 and 2022 application cycle (VIs) was conducted. Faculty scored applicants using a 5-point Likert scale in 7 areas of assessment and assigned each student to 1 of 4 tiers (tier 1 highest). A composite score for the 7 assessments (maximum score 35) was calculated. Mean and composite scores and tiers were compared between VI and IPI cycles and adjusted for within-interviewer correlations. The variance of the 2 groups were also compared. SETTING: Harbor-UCLA Medical Center, an academic, tertiary care hospital. PARTICIPANTS: General Surgery applicants for the 2019 to 2022 MATCH® application cycles. RESULTS: Four hundred forty-one faculty IPI ratings of General Surgery applicants were compared to 531VI ratings. No difference in mean composite scores, individual assessments, or tier ranking. Less variance was identified in the VI group for academic credentials (0.6 vs 0.6, pâ¯=â¯0.01), strength of letters (0.7 vs 0.4, pâ¯=â¯0.005), communication skills (0.4 vs 0.6, pâ¯=â¯0.01), personal qualities (0.2 vs 0.5, pâ¯=â¯0.02), overall sense of fit for program (0.6 vs 0.9, pâ¯=â¯0.01), and tier ranking (0.3 vs 0.4, pâ¯=â¯0.004). CONCLUSIONS: Faculty ratings of General Surgery applicants in the VI format appear to be similar to IPI. However, faculty ratings of VI applicants demonstrated less variability in scores in most assessments. This finding is potentially concerning, as it may suggest an inability of VI to detect subtle differences between applicants as comparted to IPI.

Importance: Characteristics of outstanding graduating surgical residents are currently undefined. Identifying these qualities may be important in guiding resident selection and resident education. Objective: To determine characteristics that are most strongly associated with being rated as an outstanding graduating surgical resident. Design, Setting, and Participants: The multi-institutional study had 3 phases. First, an expert panel developed a list of characteristics embodied by top graduating surgical residents. Second, groups of faculty from 14 US general-surgery residency programs ranked 2017 through 2020 graduates into quartiles of overall performance. Third, faculty evaluated their graduates on each characteristic using a 5-point Likert scale. Data were analyzed using Spearman rank-order correlation to identify which individual characteristics were associated with overall graduate performance. A least absolute shrinkage and selection operator (LASSO) ordinal regression was performed to select a parsimonious model to predict the outcome of overall performance rating from individual characteristic scores. Main Outcome and Measures: Surgical educators' rankings of general surgery residency graduates' overall performance. Results: Fifty faculty from 14 US residency programs with a median of 13 (range, 5-30) years of surgical education experience evaluated 297 general surgery residency graduates. Surgical educators identified 21 characteristics that they believed outstanding graduating surgical residents possessed. Two hundred ninety-seven surgical residency graduates were evaluated. Higher scores in every characteristic correlated with better overall performance. Characteristics most strongly associated with higher overall performance scores were surgical judgment (r = 0.728; P < .001), leadership (r = 0.726; P < .001), postoperative clinical skills (r = 0.715; P < .001), and preoperative clinical skills (r = 0.707; P < .001). The remainder of the characteristics were moderately associated with overall performance. The LASSO regression model identified 3 characteristics from which overall resident performance could be accurately predicted without measuring other qualities: surgical judgment (odds ratio [OR] per 1 level of 5-level Likert scale OR, 1.27; 95% CI, 1.03-1.51), leadership (OR, 1.27; 95% CI, 1.06-1.48), and medical knowledge (OR, 1.16; 95% CI, 1.01-1.33). Conclusions and Relevance: All individual characteristics identified by surgical educators as being qualities of outstanding graduating surgical residents were positively associated with overall graduate performance. Surgical judgment and leadership skills had the strongest individual associations. Assessment of only 3 qualities (surgical judgment, leadership, and medical knowledge) were required to predict overall resident performance ratings. These findings highlight the importance of developing specific surgical judgment and leadership skills curricula and assessments during surgical residency.

Importance: The suspension of elective operations in March 2020 to prepare for the COVID-19 surge posed significant challenges to resident education. To mitigate the potential negative effects of COVID-19 on surgical education, it is important to quantify how the pandemic influenced resident operative volume. Objective: To examine the association of the pandemic with general surgical residents' operative experience by postgraduate year (PGY) and case type and to evaluate if certain institutional characteristics were associated with a greater decline in surgical volume. Design, Setting, and Participants: This retrospective review included residents' operative logs from 3 consecutive academic years (2017-2018, 2018-2019, and 2019-2020) from 16 general surgery programs. Data collected included total major cases, case type, and PGY. Faculty completed a survey about program demographics and COVID-19 response. Data on race were not collected. Operative volumes from March to June 2020 were compared with the same period during 2018 and 2019. Data were analyzed using Kruskal-Wallis test adjusted for within-program correlations. Main Outcome and Measures: Total major cases performed by each resident during the first 4 months of the pandemic. Results: A total of 1368 case logs were analyzed. There was a 33.5% reduction in total major cases performed in March to June 2020 compared with 2018 and 2019 (45.0 [95% CI, 36.1-53.9] vs 67.7 [95% CI, 62.0-72.2]; P < .001), which significantly affected every PGY. All case types were significantly reduced in 2020 except liver, pancreas, small intestine, and trauma cases. There was a 10.2% reduction in operative volume during the 2019-2020 academic year compared with the 2 previous years (192.3 [95% CI, 178.5-206.1] vs 213.8 [95% CI, 203.6-223.9]; P < .001). Level 1 trauma centers (49.5 vs 68.5; 27.7%) had a significantly lower reduction in case volume than non-level 1 trauma centers (33.9 vs 63.0; 46%) (P = .03). Conclusions and Relevance: In this study of operative logs of general surgery residents in 16 US programs from 2017 to 2020, the first 4 months of the COVID-19 pandemic was associated with a significant reduction in operative experience, which affected every PGY and most case types. Level 1 trauma centers were less affected than non-level 1 centers. If this trend continues, the effect on surgical training may be even more detrimental.

BACKGROUND: While readmission rates of trauma patients are well described, little has been reported on rates of re-presentation to the emergency department (ED) after discharge. This study aimed to determine rates and contributing factors of re-presentation of trauma patients to the ED. METHODS: One-year retrospective analysis of discharged adult trauma patients at a county-funded safety-net level one trauma center. RESULTS: Of 1416 trauma patients, 195 (13.8%) re-presented to the ED within 30 days. Of those that re-presented, 47 (24.1%) were re-admitted (3.3% overall). The most common reasons for re-presentation were pain control and wound complications. Patients with Medicare (AOR 2.6, 95% CI 1.3 to 5.2) or other government insurance (AOR 2.5, 95% CI 1.6 to 4.1) were more likely to re-present than patients with private insurance. CONCLUSION: A considerable number of trauma patients re-presented to the ED after discharge for reasons that did not require hospitalization. Discharge planning for certain vulnerable groups should emphasize wound care, pain control and scheduled follow-up to decrease the reliance on the ED.

Early surgical intervention decreases mortality in necrotizing soft tissue infections (NSTIs). Yet, a subset of patients will not have NSTIs (non-NSTIs) at the time of exploration. We hypothesized that NSTI and non-NSTI patients had similar causative organisms and that intraoperative wound cultures could help guide management. Culture results and outcomes were compared for all patients undergoing surgery for suspected NSTIs over a seven-year-period. Of 295 patients, 240 (81.4%) had NSTIs. Of the 55 non-NSTI patients (18.6%), 50 had cellulitis and 5 had abscesses. NSTI and non-NSTI patients had similar rates of bacteremia (20.4% vs 17.6%, P = 0.66), septic shock (15.9% vs 12.7%, P = 0.68), and mortality (10.4% vs 7.2%, P = 0.62). Wound cultures were collected more often in NSTI patients (229/240, 95.4%) than in non-NSTI patients (42/55, 76.4%, P < 0.01). Non-NSTI patients had positive deep wound cultures more than half of the time (23/42, 54.8%). The microbiologic profile was similar between groups, with Methicillin Resistant Staphylococcus aureus and Group A Streptococcus occurring with the same frequency. We advocate for deep wound cultures in all patients being evaluated operatively for NSTIs even if the exploration is considered negative because these patients have similar clinical characteristics and virulent microbiology, and culture results can help guide antimicrobial therapy.

BACKGROUND: Although most surgery residents pursue fellowships, data regarding those decisions are limited. This study describes associations with interest in fellowship and specific subspecialties. METHODS: Anonymous surveys were distributed to 607 surgery residents at 19 US programs. Subspecialties were stratified by levels of burnout and quality of life using data from recent studies. RESULTS: 407 (67%) residents responded. 372 (91.4%) planned to pursue fellowship. Fellowship interest was lower among residents who attended independent or small programs, were married, or had children. Residents who received AOA honors or were married were less likely to choose high burnout subspecialties (trauma/vascular). Residents with children were less likely to choose low quality of life subspecialties (trauma/transplant/cardiothoracic). CONCLUSIONS: Surgery residents' interest in fellowship and specific subspecialties are associated with program type and size, AOA status, marital status, and having children. Variability in burnout and quality of life between subspecialties may affect residents' decisions.

BACKGROUND: Necrotizing soft tissue infections (NSTI) are aggressive infections associated with significant morbidity and mortality. Despite multiple predictive models for the identification of NSTI, a subset of patients will not have an NSTI at the time of surgical exploration. We hypothesized there is a subset of patients without NSTI who are clinically indistinguishable from those with NSTI. We aimed to characterize the differences between NSTI and non-NSTI patients and describe a negative exploration rate for this disease process. METHODS: We conducted a retrospective review of adult patients undergoing surgical exploration for suspected NSTI at our county-funded, academic-affiliated medical center between 2008 and 2015. Patients were identified as having NSTI or not (non-NSTI) based on surgical findings at the initial operation. Pathology reports were reviewed to confirm diagnosis. The NSTI and non-NSTI patients were compared using χ2 test, Fisher's exact test, and Wilcoxon rank-sum test as appropriate. A p value <0.05 was considered significant. RESULTS: Of 295 patients undergoing operation for suspected NSTI, 232 (79%) were diagnosed with NSTI at the initial operation and 63 (21%) were not. Of these 63 patients, 5 (7.9%) had an abscess and 58 (92%) had cellulitis resulting in a total of 237 patients (80%) with a surgical disease process. Patients with NSTI had higher white cell counts (18.5 vs. 14.9 k/mm3, p=0.02) and glucose levels (244 vs. 114 mg/dL, p<0.0001), but lower sodium values (130 vs. 134 mmol/L, p≤0.0001) and less violaceous skin changes (9.2% vs. 23.8%, p=0.004). Eight patients (14%) initially diagnosed with cellulitis had an NSTI diagnosed on return to the operating room for failure to improve. CONCLUSIONS: Clinical differences between NSTI and non-NSTI patients are subtle. We found a 20% negative exploration rate for suspected NSTI. Close postoperative attention to this cohort is warranted as a small subset may progress. LEVEL OF EVIDENCE: Retrospective cohort study, level III.
RESUMEN
BACKGROUND: Robotic surgery is increasingly adopted into surgical practice, but it remains unclear what level of robotic training general surgery residents receive. The purpose of our study was to assess the variation in robotic surgery training amongst general surgery residency programs in the United States. METHODS: A web-based survey was sent to 277 general surgery residency programs to determine characteristics of resident experience and training in robotic surgery. RESULTS: A total of 114 (41%) programs responded. 92% (nâ¯=â¯105) have residents participating in robotic surgeries; 68%(nâ¯=â¯71) of which have a robotics curriculum, 44%(nâ¯=â¯46) track residents' robotic experience, and 55%(nâ¯=â¯58) offer formal recognition of training completion. Responses from university-affiliated (nâ¯=â¯83) and independent (nâ¯=â¯31) programs were not significantly different. CONCLUSIONS: Many general surgery residencies offer robotic surgery experience, but vary widely in requisite components, formal credentialing, and case tracking. There is a need to adopt a standardized training curriculum and document resident competency.

OBJECTIVE: Identifying gaps in medical knowledge, patient management, and procedural competence is difficult early in surgical residency. We designed and implemented an end-of-year examination for our postgraduate year 1 residents, entitled Surgical Trainee Assessment of Readiness (STAR). Our objective in this study was to determine whether STAR scores correlated with other available indicators of resident performance, such as the American Board of Surgery in-training exam (ABSITE) and Milestone scores, and if they provided evidence of additional discriminatory value. STUDY DESIGN: Overall and component scores of the STAR exam were compared to the ABSITE and Milestone assessment scores for the 17 categorical residents that took the exam in 2016 and 2017. SETTING: Harbor-UCLA Medical Center, a university-affiliated academic medical center. PARTICIPANTS: Seventeen categorical general surgery residents. RESULTS: The STAR Total Test Score (ßâ¯=â¯2.77, pâ¯=â¯0.006) was an independent predictor of the ABSITE taken the same year, and components of the STAR were independent predictors of ABSITE taken the following year. The STAR Total Test Score was lowest in the 3 residents who had at least 1 low Milestone score assessed in the same year; and 2 of these 3 residents had at least 1 low Milestone score assigned the next year after STAR. Lastly, the Patient Care 1 and 2 Milestones assessed in the same year as STAR were uniformly scored as appropriate for level of training, yet the corresponding STAR component for those milestones demonstrated 3 residents as having deficiencies. CONCLUSIONS: We have created a multifaceted standardized STAR exam, which correlates with performance on the ABSITE and early milestone scores. It also appears to discriminate resident performance where milestone assessments do not. Further evaluation of the STAR exam with longer term follow-up is needed to confirm these initial findings.

BACKGROUND: The objectives of this study were to examine the incidence and severity of early acute respiratory distress syndrome (ARDS) according to the Berlin Definition and to identify risk factors associated with the development of early post-traumatic ARDS. METHODS: A 2.5-year retrospective database of adult trauma patients who required mechanical ventilation for greater than 48 hours at a level 1 trauma center was analyzed for variables predictive of early (<48 hours after injury), mild, moderate, and severe ARDS and in-hospital mortality. RESULTS: Of 305 patients, 59 (19.3%) developed early ARDS: mild, 27 (45.8%); moderate, 26 (44.1%); and severe, 6 (10.1%). Performance of an emergent thoracotomy, blunt mechanism, and fresh frozen plasma administration were independently associated with the development of early ARDS. ARDS was not predictive of mortality. CONCLUSIONS: Trauma patients with blunt mechanism, who receive fresh frozen plasma, or undergo thoracotomy, are at risk of developing early ARDS.

Preoperative diagnosis of ischemic bowel in patients with small bowel obstruction (SBO) is a clinical challenge. The aim of this study was to identify preoperative variables associated with ischemic bowel found at operative exploration. We performed a 5-year retrospective review of patients admitted to a university affiliated, county funded hospital who underwent exploratory laparoscopy or laparotomy for SBO. Patients were excluded if they had a known preoperative malignancy or hernia on physical examination. Multivariate logistic regression was used to determine factors independently associated with bowel ischemia or ischemic perforation. One hundred and sixteen patients underwent exploratory surgery for SBO. Mean age was 52 ± 14 years and most were male [64 (55.2%)]. Adhesions [92 (79.3%)] were the most common etiology of obstruction. Leukocytosis (P = 0.304) and acidosis (P = 0.151) were not significantly associated with ischemia or ischemic perforation. In addition, history of prior SBO (P = 0.618), tachycardia (P = 0.111), fever (P = 0.859), and time from admission to operation (P = 0.383) were not predictive of ischemic bowel. However, hyponatremia (≤134 mmol/L) and CT scan findings of wall thickening or a suspected closed loop were independently associated with bowel ischemia. Awareness of these predictors should heighten the concern for ischemic bowel in patients presenting with SBO.

Necrotizing soft tissue infections (NSTIs) are a major source of morbidity and mortality, yet predictors of mortality for these critically ill patients remain poorly characterized. The aim of this study was to identify risk factors for mortality in patients with NSTI. We performed a retrospective review of all patients presenting with an NSTI to our county-funded, academic medical center between 2008 and 2013. Admission characteristics, comorbidities, laboratory values, time to operation, and perioperative cultures were assessed to identify predictors of mortality. During the 5-year study period, 138 patients were admitted with a NSTI; 20 (14.5%) of the patients died. Univariate predictors of mortality included bandemia, elevated creatinine, low bicarbonate, elevated lactate, a lower admission temperature, and shorter duration of presenting symptoms. Using Classification And Regression Tree analysis and subsequent logistic regression, bands greater than 25 per cent (odds ratio [OR], 8.0; 95% confidence interval [CI], 2.7 to 24.1; P = 0.0002), duration of symptoms less than 3.5 days (OR, 4.0; 95% CI, 1.2 to 13.9; P = 0.03), and temperature 37°C or less (OR, 3.6; 95% CI, 1.1 to 11.8; P = 0.03) were found to be independent predictors of mortality. Awareness of these predictors should prompt aggressive management of this at-risk population.

Laparoscopy and work-hour restrictions are altering surgical training. We hypothesized interns were no longer gaining experience in open appendectomy, historically an intern index case. We retrospectively reviewed Accreditation Council for Graduate Medical Education (ACGME) case logs of postgraduate Year (PGY) 1 general surgery trainees from our academic teaching program for the last 9 years. Number of appendectomies performed (Current Procedural Terminology codes 44950, 44960, and 44970) were recorded and analyzed. The national ACGME database was similarly evaluated for resident experience during junior (PGY-1 to 4) years. Data were available for 47 residents completing internship at our institution between 2003 and 2011. Mean number of appendectomies performed per intern steadily decreased throughout the study period from 22 in 2003 to 5 in 2011 (P=0.0367). Mean percentage of cases done open decreased from 79.5 to 2.4 per cent (P=0.0001). National data found residents graduating in the year 2000 performed an average of 26.6 open appendectomies during junior years, whereas those graduating in 2011 had done only 13.7. Surgical trainees are performing fewer open appendectomies than just several years ago. Open appendectomy traditionally served as an introduction to open surgery. Because outcome differences are small between open and laparoscopic appendectomy, we propose teaching institutions consider performing open appendectomies in select patients to preserve an important educational experience.

Clinical predictors of perioperative mortality in geriatric patients undergoing emergent general surgery have not been well described. The purpose of this study was to determine the incidence of postoperative morbidity and mortality in geriatric patients and factors associated with mortality. A retrospective review of patients 65 years of age or older undergoing emergent general surgery at a public teaching hospital was performed over a 7-year period. Data collected included demographics, comorbidities, laboratory studies, perioperative morbidities, and mortality. Descriptive statistics and predictors of morbidity and mortality are described. The mean age was 74 years. Indications for surgery included small bowel obstruction (24%), diverticulitis (20%), perforated viscous (16%), and large bowel obstruction (9%). The overall complication rate was 41 per cent with six cardiac complications (14%) and seven perioperative (16%) deaths. Mean admission serum creatinine was significantly higher in patients who died (3.6 vs 1.5 mg/dL, P = 0.004). Mortality for patients with an admission serum creatinine greater than 2.0 mg/dL was 42 per cent (5 of 12) compared with 3 per cent (2 of 32) for those 2.0 mg/dL or less (OR, 10.7; CI, 1.7 to 67; P = 0.01). Morbidity and mortality in geriatric patients undergoing emergency surgery remains high with the most significant predictor of mortality being the presence of renal insufficiency on admission.

Elderly trauma patients have worse outcomes than their younger counterparts. Early risk stratification remains difficult, particularly because traditional vital signs are less reliable. We hypothesized that arrival lactate and base deficit (BD) could be used to predict mortality in elderly trauma patients with a normal admission blood pressure. We retrospectively evaluated the prospectively collected trauma registry at our urban Level I trauma center between 2003 and 2009. Patients sustaining blunt trauma, age 55 years or older, with a systolic blood pressure 90 mmHg or higher, and who had arterial lactate and/or BD measured within 4 hours of arrival comprised the study group. Primary outcomes were in-hospital and 24-hour mortality. There were 364 patients with a lactate and 324 with a BD drawn. Patients with a lactate 2.5 mmol or greater were 3.7 times more likely to die than those with a lactate less than 2.5 mmol (95% CI, 1.6 to 8.2; P = 0.0018). The OR for mortality was 5.2 (95% CI, 2.5 to 11.2; P < 0.0001) in patients with a BD -4 or less. Elevated lactate and BD were even stronger predictors of early mortality (within first 24 hours). After increasing the hypotension threshold to a systolic blood pressure 110 mmHg or greater, lactate and BD remained highly predictive of in-hospital and 24-hour mortality.

Motor vehicle collisions (MVCs) continue to be a leading cause of traumatic death, yet there is a paucity of data regarding racial/ethnic differences in injury severity, use of restraints, and outcomes. This study determines whether racial/ethnic disparities exist in adult MVC victims. A retrospective review of patients (age older than 18 years) involved in MVC in Los Angeles County from 2004 to 2009 was performed. Main outcome measures were hospital length of stay, mortality, and complication rate. Independent variables evaluated included race/ethnicity, use of restraints, age, gender, Injury Severity Score (ISS), and Glasgow Coma Scale. During the 5-year study period, 22,444 patients were involved in an MVC in Los Angeles County. Overall restraint use was 69 per cent, lowest in blacks (67%) and Hispanics (68%). Mortality and morbidity rates were both 3 per cent for all racial/ethnic groups. On multivariable analysis, higher ISS, older age, male gender, not wearing a seatbelt, and being Asian increased the risk of death. In conclusion, our study demonstrated racial/ethnic differences in MVC victims, particularly identifying that Hispanics and blacks were less likely to be restrained and thus could be the target of future injury prevention programs.

In the 80-hour work week era, optimal distribution of the residency workforce is critical. Little data exist as to whether current hours of hospital staffing parallel trends in trauma activity. The purpose of this study was to determine peak periods of trauma volume, severity, need for operative intervention, and mortality and determine if there are differences in mortality based on time period of arrival. We performed a retrospective analysis of the 17,167 patients admitted to our academic Level I trauma center between 2000 and 2007. Each admission was plotted against time of arrival and trends noted. A significant increase in activity occurred between 1700 and 0100 hours. Compared with other shifts, this shift had a disproportionately higher number of patients with penetrating injuries, need for operative intervention, Injury Severity Score (ISS) greater than 15, and death (P < 0.0001). After adjusting for ISS and penetrating trauma, arrival time was not predictive of mortality (OR 0.97, CI 0.87-1.08, P = 0.6). In conclusion, a peak in trauma activity occurs during an evening shift between 1700 and 0100 hours. In an era of optimizing resident training within the constraints of an 80-hour work week, strong consideration should be made for deploying personnel to match these findings.

BACKGROUND: As obesity continues to run rampant in our society, an understanding of its adverse effect after traumatic injury is starting to unfold. We hypothesize that obesity negatively impacts head-injured patients, and the current study intends to compare obese and lean patients with traumatic brain injury (TBI). METHODS: This is a retrospective study evaluating all blunt trauma patients with TBI admitted to the intensive care unit (ICU) in our urban, Level I trauma center from 1998 until 2003. Body mass index (BMI) was used to categorize patients as either lean (BMI <30 kg/m2) or obese (BMI > or =30 kg/m2). Admission demographics, type and severity of head injury, and associated injuries were recorded for each patient. Primary outcome was mortality, while secondary outcomes were cause of death, complications, and for survivors, days of mechanical ventilation, ICU length of stay, and hospital length of stay. Obese and lean patients were compared using univariate analysis and multivariate stepwise logistic regression. In addition, a subgroup analysis of patients with isolated head injury was performed. RESULTS: There were 690 patients with TBI admitted to the ICU during the study period, with 129 (19%) obese patients (BMI = 34 +/- 5 kg/m2) and 561 (81%) lean patients (BMI = 24 +/- 4 kg/m2). The two groups were similar with the exceptions that obese patients were older (46 +/- 20 years versus 39 +/- years, p < 0.01), had lower admission systolic blood pressure (125 +/- 38 mm Hg versus 134 +/- 30 mm Hg, p = 0.01), and more often sustained an associated chest injury (46% versus 35%, p = 0.03). Obese patients with TBI had a trend toward more complications (34% versus 28%, p = 0.17) and a higher mortality (36% versus 25%, p = 0.02). However, stepwise logistic regression failed to identify obesity as an independent risk factor for either morbidity or mortality. In addition, obese patients with isolated head injury had no increase in complications or death. CONCLUSIONS: Although obese patients suffer more complications and higher mortality than lean patients after TBI, this adverse effect seems to be due to age, lower admission blood pressure, and more associated chest injury, rather than a direct result of the obese state.
