Association of Residency Applicants' Hobbies and Subsequent Technical Proficiency Ratings as General Surgery Chief Residents: A Multi-Institutional Study.

OBJECTIVE: To determine whether participation in certain hobbies (e.g., participation in sports, playing musical instruments, or other hobbies requiring fine motor skills), preresidency, are associated with higher technical skills ratings at the time of residency graduation. DESIGN: Faculty members from 14 general surgery residency programs scored individual graduates from 2017 to 2020 on their technical skills using a 5-point Likert scale. Hobbies for these residents were collected from their Electronic Residency Application Service (ERAS) data. A single reviewer classified each ERAS hobby into predefined categories including musical instruments, sports requiring hand-eye coordination, team sports, and activities necessitating hand-eye coordination. Spearman correlation coefficients were calculated for the relationship between each category of hobby-as well as the total number of hobbies in each category-and the outcome of surgical faculty ratings of residents' technical surgical skills during their last year of residency. A proportional odds model including the above predictive variables was also fit to the data. SETTING: Fourteen general surgery residency programs. PARTICIPANTS: General surgery residency graduates from 14 different programs from 2017 to 2020. RESULTS: There were 296 residents across 14 institutions. The average ranking of residents' technical skills was 3.24 (SD 1.1). A total of 40% of residents played sports involving hand-eye coordination, 31% played team sports, 28% participated in nonsport hobbies that require eye-hand coordination, and 20% played musical instruments. Correlation coefficients were not statistically significant for any of the categories. In the proportional odds model, none of the variables were associated with statistically significant increased odds of a higher technical skills rating. CONCLUSIONS: There was no correlation between general surgery chief residents' technical skills as rated by faculty, and self-reported pre-residency hobbies on the ERAS application. These findings suggest such hobbies prior to residency are unlikely to predict future technical skills prowess.

Impact of Automated Reminder Calls in a Safety-Net Setting on Surgical Clinic No-Show Rates.

In surgical clinics, missed appointments may lead to delayed diagnosis and postponed surgical intervention. Automated reminder calls (robocalls) have replaced live staff phone calls in many systems as a cost-saving measure. This study aims to evaluate whether robocalls reduced the outpatient appointment no-show rate for surgical patients in a county hospital. Demographic and clinic data from two surgical clinics at a safety net hospital were collected over two time periods: 3-months immediately before robocalls went live and 3-months immediately after robocalls went live. No-show rates were compared between time periods. Multivariate analysis confirmed that robocalls were independently associated with reduced no-show rates (OR: 1.32; 95% CI: 1.0-1.7; P = .032). In addition, new appointments were independently predictive of higher no-show rates (OR: 1.32; 95% CI: 1.0-1.7; P = .048). Robocalls appear to be an effective tool for improving appointment attendance overall. Furthermore, robocalls may free limited staff to perform higher value work in the healthcare system.

Faculty Scoring of General Surgery Residency Interviewees: A Comparison of In-Person and Virtual Interview Formats.

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, p = 0.01), strength of letters (0.7 vs 0.4, p = 0.005), communication skills (0.4 vs 0.6, p = 0.01), personal qualities (0.2 vs 0.5, p = 0.02), overall sense of fit for program (0.6 vs 0.9, p = 0.01), and tier ranking (0.3 vs 0.4, p = 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.

A Sisyphean Task for Residents: Preparing Literature Reviews About Adverse Events Presented at Morbidity and Mortality Conferences.

OBJECTIVE: Surgery Morbidity and Mortality (M&M) 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. DESIGN: 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. SETTING: Tulane University General Surgery program, New Orleans, LA, USA. PARTICIPANTS: All clinically active residents. RESULTS: 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. CONCLUSIONS: 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.

Should Robotic Surgery Training Be Prioritized in General Surgery Residency? A Survey of Fellowship Program Director Perspectives.

OBJECTIVE: Robotic surgery has been increasingly incorporated into the subspecialties of colorectal (CRS), minimally invasive/bariatric (MIS/Bar), and surgical oncology/hepatobiliary (SO/HPB) surgery, yet its impact on fellowship applicant evaluation and contribution to postresidency training remains undefined. The aim of our study was to evaluate how robotic training during General Surgery (GS) residency affects an applicant's competitiveness from the perspective of fellowship programs. DESIGN: A web-based survey was sent to all 235 accredited fellowship programs in CRS (n = 66), MIS/Bar (n = 122), and SO/HPB (n = 47) within the United States and Canada. Fellowship programs were queried on the import of robotic surgery training during GS residency and its impact on an applicant's match potential. RESULTS: Of 235 programs, 155 (66%) responded to the survey - 42 (63.6%) CRS, 87 (71.3%) MIS/Bar, and 26 (55.3%) SO/HPB. Of responding programs, 147 (94.8%) have a surgical robot at their institution, and 131 (84.5%) have fellows actively operating at the console. Overall, 107 (69%) fellowship program directors rated robotic training during surgery residency as "somewhat" or "very" important for residents seeking fellowship. While 95 (61.3%) programs said GS residents should not prioritize robotic training, 60 (38.7%) felt they should, and 38 (24.5%) were more likely to rank an applicant higher if they had some console exposure. Still, 69.7% (n = 108) of programs expect no robotic experience for incoming fellows. CONCLUSIONS: This study demonstrates that most fellowship programs have low expectations of robotic experience for incoming fellows. Still, it is notable that nearly a quarter of programs would rank an applicant more highly if they had robotic console exposure. While these findings appear reassuring to residents with limited access to robotic training, residency programs should be alerted to the growing importance of robotic exposure.

Predictors of Morbidity and Mortality in Complex Paraesophageal Hernia Repair: A NSQIP Analysis.

Paraesophageal hernia (PEH) repair is typically performed electively. Complex PEHs (obstructed or gangrenous) require more urgent repair and can have significant complications. Although elective repair is primarily laparoscopic, limited data are available on the use of laparoscopy for complex cases. Patients undergoing complex PEH repair were identified from the NSQIP database, and predictors of morbidity and mortality were compared for 2473 laparoscopic and 861 open repairs. Compared with the laparoscopic approach, emergent surgeries (36.7% vs 10.8%, P < 0.001) and preoperative sepsis (22.9% vs 7.4%, P < 0.001) were more common in the open group. Operative times were shorter for open repairs (152.6 vs 172.2 minutes, P = 0.03). However, open repair was associated with increased morbidity (28.2% vs 11%, P < 0.001) and mortality (5.2% vs 1.4%, P < 0.001), likely because of higher rates of preoperative comorbidities in the open group. On multivariable regression analysis, preoperative sepsis was associated with increased mortality and morbidity, whereas laparoscopic repair was associated with decreased morbidity. If laparoscopic repair can be safely completed, it is associated with decreased morbidity, despite longer operative times.

Can Deficiencies in Performance Be Identified Earlier in Surgical Residency? An Initial Report of a Surgical Trainee Assessment of Readiness Exam.

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 (ß = 2.77, p = 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.

Outcomes of Combined Hernia Repair and Peritoneal Dialysis Catheter Placement: A NSQIP Analysis.

Historically, hernias were repaired before peritoneal dialysis (PD) catheter placement to obviate hernia complications, or after PD catheter placement once hernias became symptomatic or complicated. The aim of this study was to evaluate the outcomes and safety of combined hernia repair and PD catheter placement (HPD) compared with PD catheter placement alone. Within the NSQIP databases (2005-2014), 4406 patients who underwent PD catheter placement alone and 330 patients who underwent HPD were identified. Thirty-day outcomes were compared. Overall, HPD patients were older (61 vs 57 years, P < 0.001), male (72.4% vs 56.1%, P < 0.001), and more likely to have ascites (3.6% vs 1.0%, P < 0.001). Umbilical hernias (87.9%) were most commonly repaired. There was no significant difference in mortality, morbidity, superficial surgical site infection, deep SSI, organ/space SSI, readmission, or reoperation rates. HPD was associated with shorter length of stay (1.1 vs 1.7 days, P = 0.010) and longer mean operative time (66.1 vs 43.7 minutes, P < 0.001). On multivariate analyses, HPD was not an independent predictor of morbidity or mortality. In conclusion, HPD can be safely performed to prevent future complications and additional operations.

Kendrick's extrication device and unstable pelvic fractures: Should a trochanteric belt be added? A cadaveric study.

INTRODUCTION: Pre-hospital pelvic stabilisation is advised to prevent exsanguination in patients with unstable pelvic fractures (UPFs). Kendrick's extrication device (KED) is commonly used to extricate patients from cars or crevasses. However the KED has not been tested for potential adverse effects in patients with pelvic fractures. The aim of this study was to examine the effect of the KED on pubic symphysis diastasis (SyD) with and without the use of a trochanteric belt (TB) during the extraction process following a MVC. MATERIALS AND METHODS: Left-sided "open-book" UPFs were created in 18 human cadavers that were placed in seven different positions simulating pre-extraction and extraction positions using the KED with and without a TB in two different positions (through and over the thigh straps). The SyD was measured using anteroposterior radiographs. The effects of the KED with and without TB, on the SyD, were evaluated. RESULTS: The KED alone resulted in a non-significant increase of the SyD compared to baseline, whereas the addition of a TB to the KED resulted in a significant reduction of the SyD (p<0.001). The TB through the straps provided a significantly better reduction than the TB over the straps in the extracted position (p<0.05). CONCLUSION: Our study demonstrated that a TB in combination with the KED on UPFs is an effective way to achieve early reduction. The addition of the TB in combination with the KED could be considered for Pre-Hospital Trauma Life Support (PHTLS) training protocols.

Clamshell incision versus left anterolateral thoracotomy. Which one is faster when performing a resuscitative thoracotomy? The tortoise and the hare revisited.

BACKGROUND: The clamshell incision (CI) offers a better exposure than the left anterolateral thoracotomy (LAT) as a resuscitative thoracotomy. Most surgeons will have to manage a heart wound only once or twice in their career. The patient's survival depends on how fast the surgeon can control the heart wound; however, it is unclear which of the two incisions allows for faster control in the hands of inexperienced surgeons. The aim of this study was to compare the time needed to access and control a standardized stab wound to the right ventricle, by inexperienced surgical trainees, by LAT or CI; we hypothesized that the CI does not take longer than the LAT. METHODS: Sixteen residents were shown a video on how to perform both procedures. They were randomly assigned to control a standardized stab wound of the right ventricle on perfused human cadavers by LAT (n = 8) or CI (n = 8). Access time (skin to maximal exposure), control time (maximal exposure until control of the heart wound) and total time (the sum of access and control times) were recorded. RESULTS: Total time was 6.62 min [3.20-8.14] (median [interquartile range]) for LAT and 4.63 min [3.17-6.73] for CI (p = 0.46). Access time was 2.39 min [1.21-2.76] for LAT and 2.33 min [1.58-4.86] for CI (p = 0.34). Control time was 4.16 min [2.32-5.49] for LAT and 1.85 min [1.38-2.23] for CI (p = 0.018). CONCLUSIONS: The time needed from skin incision until cardiac wound control via CI was not longer than via LAT and the easier control of the cardiac wound when using CI was confirmed.

Effectiveness of systems changes suggested by simulation of adverse surgical outcomes.

Background: Simulation of adverse outcomes (SAO) has been described as a technique to improve effectiveness of root cause analysis (RCA) in healthcare. We hypothesise that SAO can effectively identify unsuspected root causes amenable to systems changes. Methods: Systems changes were developed and tested for effectiveness in a modified simulation, which was performed eight times, recorded and analysed. Results: In seven of eight simulations, systems changes were effectively utilised by participants, who contacted anaesthesia using the number list and telephone provided to express concern. In six of seven simulations where anaesthesia was contacted, they provided care that avoided the adverse event. In two simulations, the adverse event transpired despite implemented systems changes, but for different reasons than originally identified. In one case, appropriate personnel were contacted but did not provide the direction necessary to avoid the adverse event, and in one case, the telephone malfunctioned. Conclusions: Systems changes suggested by SAO can effectively correct deficiencies and help improve outcomes, although adverse events can occur despite implementation. Further study of systems concepts may provide suggestions for changes that function more reliably in complex healthcare systems. The information gathered from these simulations can be used to identify potential deficiencies, prevent future errors and improve patient safety.

Impact of infusion rates of fresh frozen plasma and platelets during the first 180 minutes of resuscitation.

BACKGROUND: Whether high-ratio resuscitation (HRR) provides patients with survival advantage remains controversial. We hypothesized a direct correlation between HRR infusion rates in the first 180 minutes of resuscitation and survival. STUDY DESIGN: This was a retrospective analysis of massively transfused trauma patients surviving more than 30 minutes and undergoing surgery at a level 1 trauma center. Mean infusion rates (MIR) of packed red blood cells (PRBC), fresh frozen plasma (FFP), and platelets (Plt) were calculated for length of intervention (emergency department [ED] time + operating room [OR] time). Patients were categorized as HRR (FFP:PRBC > 0.7, and/or Plts: PRBC > 0.7) vs low-ratio resuscitation (LRR). Student's t-tests and chi-square tests were used to compare survivors with nonsurvivors. Cox proportional hazards regression models and Kaplan-Meier curves were generated to evaluate the association between MIR for FFP:PRBC and Plt:PRBC and 180-minute survival. RESULTS: There were 151 patients who met criteria: 121 (80.1%) patients survived 180 minutes (MIR:PRBC 71.9 mL/min, FFP 92.0 mL/min, Plt 3.5 mL/min) vs 30 (19.9%) who did not survive (MIR:PRBC 47.3 mL/min, FFP 33.7 mL/min, Plt 1.1 mL/min), p = 0.43, p < 0.0001 and p < 0.011, respectively. A Cox regression model evaluated PRBC rate, FFP rate, and Plt rate (mL/min) as mortality predictors within 180 minutes to assess if they significantly affected survival (hazard ratios 1.01 [p = 0.054], 0.97 [p < 0.0001], and 0.75 [p = 0.01], respectively). Another model used stepwise Cox regression including PRBC rate, FFP rate, and Plt rate (hazard ratios 1.00 [p = 0.85], 0.97 [p < 0.0001], and 0.88 [p = 0.24], respectively), as well as possible confounding variables. CONCLUSIONS: This is the first study to examine effects of MIRs on survival. Further studies on the effects of narrow time-interval analysis for blood product resuscitation are warranted.

To TQIP or not to TQIP? That is the question.

The Trauma Quality Improvement Program (TQIP) reports a feasible mortality prediction model. We hypothesize that our institutional characteristics differ from TQIP aggregate data, questioning its applicability. We conducted a 2-year (2008 to 2009) retrospective analysis of all trauma activations at a Level 1 trauma center. Data were analyzed using TQIP methodology (three groups: blunt single system, blunt multisystem, and penetrating) to develop a mortality prediction model using multiple logistic regression. These data were compared with TQIP data. Four hundred fifty-seven patients met TQIP inclusion criteria. Penetrating and blunt trauma differed significantly at our institution versus TQIP aggregates (61.9 vs 7.8%; 38.0 vs 92.2%, P < 0.01). There were more firearm mechanisms of injury and less falls compared with TQIP aggregates (28.9 vs 4.2%; 8.5 vs 34.8%, P < 0.01). All other mechanisms were not significantly different. Variables significant in the TQIP model but not found to be predictors of mortality included Glasgow Coma Score motor 2 to 5, systolic blood pressure greater than 90 mmHg, age, initial pulse rate in the emergency department, mechanism of injury, head Abbreviated Injury Score, and abdominal Abbreviated Injury Score. External benchmarking of trauma center performance using mortality prediction models is important in quality improvement for trauma patient care. From our results, TQIP methodology from the pilot study may not be applicable to all institutions.

Using simulation to improve root cause analysis of adverse surgical outcomes.

OBJECTIVE: The purpose of this study was to develop and test a simulation method of conducting investigation of the causality of adverse surgical outcomes. DESIGN: Six hundred and thirty-one closed claims of a major medical malpractice insurance company were reviewed. Each case had undergone conventional root cause analysis (RCA). Claims were categorized by comparing the predominant underlying cause documented in the case files. Three cases were selected for simulation. SETTING: All records (medical and legal) were analyzed. Simulation scenarios were developed by abstracting data from the records and then developing paper and electronic medical records, choosing appropriate STUDY PARTICIPANTS: including test subjects and confederates, scripting the simulation and choosing the appropriate simulated environment. INTERVENTION: In a simulation center, each case simulation was run 6-7 times and recorded, with participants debriefed at the conclusion. MAIN OUTCOME MEASURES: Sources of error identified during simulation were compared with those noted in the closed claims. Test subject decision-making was assessed qualitatively. RESULTS: Simulation of adverse outcomes (SAOs) identified more system errors and revealed the way complex decisions were made by test subjects. Compared with conventional RCA, SAO identified root causes less focused on errors by individuals and more on systems-based error. CONCLUSIONS: The use of simulation for investigation of adverse surgical outcomes is feasible and identifies causes that may be more amenable to effective systems changes than conventional RCA. The information that SAO provides may facilitate the implementation of corrective measures, decreasing the risk of recurrence and improving patient safety.

Impact of hormonal protection in blunt and penetrating trauma: a retrospective analysis of the National Trauma Data Bank.

Over the last decade, gender and age-related hormonal status of trauma patients have been increasingly recognized as outcome factors. In the present study, we examine a large cohort of trauma patients to better appraise the effects of gender and age on patient outcome after blunt and penetrating trauma. We hypothesize that adult females are at lower risk for complications and mortality relative to adult males after both blunt and penetrating trauma. A retrospective analysis was conducted of the National Trauma Data Bank examining hormonally active females for advantages in survival and outcome after blunt and/or penetrating trauma. Over 1.4 million incident trauma cases were identified between 2002 and 2006. Multiple logistic regressions were calculated for associations between gender and outcome, stratified by injury type, age, comorbidity, Injury Severity Score (ISS), and complications. Risk factors associated with mortality in our multiple logistic regression analyses included: penetrating trauma (odds ratio [OR, 2.31; 95% confidence interval [CI], 2.27 to 2.36); adult male (OR, 1.45; 95% CI, 1.41 to 1.49); and ISS 15 or greater (OR, 14.68; 95% CI, 14.38 to 14.98). Adult females demonstrated a survival advantage over adult males (OR, 0.69; 95% CI, 0.67 to 0.71). Adult females with ISS less than 15 demonstrated a distinct survival advantage compared with adult males after both blunt and penetrating trauma. These results warrant further investigation into the role of sex hormones in trauma.

When enough is enough: impact of packed red blood cells in massive transfusion outcomes.

Massive transfusion protocol (MTP) with fresh-frozen plasma and packed red blood cells (PRBCs) in a 1:1 ratio is one of the most common resuscitative strategies used in patients with severe hemorrhage. There are no studies to date that examine the best postoperative hematocrit range as a marker for survival after MTP. We hypothesize a postoperative hematocrit dose-dependent survival benefit in patients receiving MTP. This was a 53-month retrospective analysis of patients with intra-abdominal injuries requiring surgery and transfusion of 10 units PRBCs or more at a single Level I trauma center. Groups were defined by postoperative hematocrit (less than 21, 21 to 29, 29.1 to 39, and 39 or more). Kaplan-Meier (KM) survival probability was calculated. One hundred fifty patients requiring operative abdominal explorations and 10 units PRBCs or more were identified. There were no significant differences in demographics between groups. When comparing postoperative hematocrit groups, relative to a hematocrit of less than 21 per cent in KM survival analysis, an overall survival advantage was only evident in patients transfused to hematocrits 29.1 to 39 per cent (P < 0.03; odds ratio [OR], 0.284; 95% confidence interval [CI], 0.089 to 0.914). This survival advantage was not seen in the other groups (21 to 29: OR, 0.352; 95% CI, 0.103 to 1.195 or 39% or greater: OR, 0.107; 95% CI, 0.010 to 1.121). This is the first study to examine the impact of postoperative hematocrit as an indicator of survival after MTP in the trauma patient. Transfusion to hematocrits between 29.1 and 39 per cent conveyed a survival benefit, whereas resuscitation to supraphysiologic hematocrits 39 per cent or greater conveyed no additional survival benefit. This study highlights the need for judicious PRBC administration during MTP and its potential impact on survival in patients with postoperative supraphysiologic hematocrits.
