Surgical critical care: Is work-life expectancy increasing? An analysis of American Board of Surgery recertification rates across subspecialties

The practice of surgical critical care (SCC) has traditionally necessitated additional in-house, extended night and weekend clinical commitments, which can be viewed as less desirable for many surgeons. Therefore, the authors have observed that some SCC surgeons elect to transition their practice to focus solely on general surgery (GS) rather than continuing practicing both SCC and GS. We hypothesized that surgeons with a practice focused on SCC are more likely to make the transition to a GS practice than those who have certification in other subspecialties that are certified through the American Board of Surgery.

A Look at Demographics and Transition to Virtual Assessments: An Analysis of Bias in the American Board of Surgery General Surgery Certifying Exams

OBJECTIVE

The goals of this study were (1) to assess if examiner ratings in the American Board of Surgery (ABS) General Surgery Cetifying Exam (CE) are biased based on the gender, race, and ethnicity of the candidate or the examiners, and (2) if the format of delivering of the exams, in-person or virtual, affects how examiners rate candidates.

DESIGN

We included every candidate-examiner combination for first time takers of the general surgery oral exam. Total scores and pass/fail outcomes based on the 4 scores given by examiners to candidates were analyzed using multilevel models, with candidates as random effects. Explanatory variables included the gender, race, and ethnicity of candidates and examiners, and the format of the exam (in-person or virtual). Candidates' first attempt scores on the ABS General Surgery Qualifying Exam (QE) were also included in the models to control for the baseline knowledge of the candidate. Three sets of models were evaluated for each demographic variable (gender, race, ethnicity) due to missingness in data. p-values and coefficients of determination R2 were used to quantify the statistical and practical significance of the model coefficients (an existent relationship between the explored variables on CE scores was considered statistically and practically significant if the p-value was lower than 0.01 and R2 higher than 1%).

PARTICIPANTS

All first-time takers of the American Board of Surgery General Surgery Certifying Exam from 2016 to 2022 that had demographic data, and the examiners that participated in those exams.

RESULTS

The number of candidates/examiners for the 3 sets of models was 8665/514 (gender), 5906/465 (race), and 4678/295 (ethnicity). The demographic variables, format of the exam, or their interactions were not found to significantly relate to examiner-candidate ratings or pass/fail outcomes. The only variable that was significantly related to CE scores was candidates' QE scores, which was added to the models as a measure of candidates' initial knowledge; this held for all models for total scores (F[1,8659] = 1069.89, p-value < 0.01, R2 = 5% [gender models], F(1,5696.3) = 589.13, p-value < 0.01, R2 = 5% [race models], F(1,4459.5) = 278.33, p-value < 0.01, R2 = 5% [ethnicity models]), and pass/fail outcomes (CI = 1.61-1.73, p-value < 0.01, R2 = 3% [gender models], CI = 1.67-1.85, p-value < 0.01, R2 = 3% [race models], CI = 2.17-2.90, p-value < 0.01, R2 = 3% [ethnicity models]).

CONCLUSIONS

This study shows that there is not a relationship between candidate and examiner gender, race, or ethnicity, and exam outcomes based on statistical models looking at examiner-candidate ratings and pass/fail outcomes. In addition, the delivery of the certifying exam in a virtual format appears to have no statistical impact on outcomes compared to in-person delivery. This suggests that the ABS is performing well in both demographic bias and virtual space.

How Does the Sequence of the American Board of Surgery Examinations Impact Pass/Fail Outcomes?

OBJECTIVE

Historically, the American Board of Surgery required surgeons to pass the qualifying examination (QE) before taking the certifying examination (CE). However, in the 2020-2021 academic year, with mitigating circumstances related to COVID-19, the ABS removed this sequencing requirement to facilitate the certification process for those candidates who were negatively impacted by a QE delivery failure. This decoupling of the traditional order of exam delivery has provided a natural comparator to the traditional route and an analysis of the impact of examination sequencing on candidate performance.

METHODS

All candidates who applied for the canceled July 2020 QE were allowed to take the CE before passing the QE. The sample was then reduced to include only first-time candidates to ensure comparable groups for performance outcomes. Logistic regression was used to analyze the relationship between the order of taking the QE and the CE, controlling for other examination performance, international medical graduate status, and gender.

RESULTS

Only first-time candidates who took both examinations were compared (n=947). Examination sequence was not a significant predictor of QE pass/fail outcomes, OR=0.54; 95% CI, 0.19-1.61, P =0.26. However, examination sequence was a significant predictor of CE pass/fail outcomes, OR=2.54; 95% CI, 1.46-4.68, P =0.002.

CONCLUSIONS

This important study suggests that preparation for the QE increases the probability of passing the CE and provides evidence that knowledge may be foundational for clinical judgment. The ABS will consider these findings for examination sequencing moving forward.

Implementation of entrustable professional activities in multiple surgical residencies: A quality improvement approach

BACKGROUND

The COVID-19 pandemic decreased the operative case volume for surgical residents. Our institution implemented Entrustable Professional Activities (EPAs) in all core surgical training programs to document the competency of graduating residents. Continuation of this project aimed to improve implementation.

METHODS

This project occurred at a large academic center with eight surgical specialties during the 2020-21 (Year 1) and 2021-22 (Year 2) academic years. Each specialty chose five EPAs, and residents were asked to obtain three micro-assessments per EPA. After the initial pilot year, program directors were surveyed regarding perceptions of EPA utility and barriers to implementation.

RESULTS

Seventy senior residents completed 732/906 (80.8%) micro-assessments. Of these, 99.6% were deemed practice ready. Total micro-assessment completion rates in four specialties, four specific EPAs (including one EPA identified "at risk" due to the COVID-19 pandemic), and overall were significantly higher in Year 2 than Year 1 (p ​< ​0.05) CONCLUSIONS: Implementing EPAs in all core surgical specialties at an institution is achievable, though expectedly initially imperfect. An ongoing quality collaborative initiative focused on barriers to implementation can improve completion rates.

How Did We Get Here and Where Are We Going? Career Trajectories of United States General Surgery Residency Program Directors

OBJECTIVE

To develop the future of United States (US) surgical education leadership, surgical trainees and early career faculty who aspire to become program directors (PDs) must understand the potential career pathways and requisite skills and experience to become a general surgery residency PD. The objective of this study was to understand the demographics, career experiences, and professional satisfaction of US PDs in general surgery.

DESIGN

An anonymous, cross-sectional survey utilizing a novel instrument.

SETTING

An electronic survey distributed to US general surgery PDs between June and November 2022 PARTICIPANTS: PDs of US general surgery residency programs. A list of the Accrediting Council for Graduate Medical Education (ACGME)-accredited general surgery PDs was created from the ACGME list from the 2022 to 23 academic year.

RESULTS

The survey achieved a response rate of 46.2% (159/344). Only 32.1% of PDs identified as female and 67.3% identified as male with 1 respondent preferring not to identify their gender. PDs were White or Caucasian (68.6%), Asian (13.8%), and Black (3.7%); 4.4% were Hispanic or Latino. Only 83.7% of PDs completed fellowship training. PDs have been in the role for an average of 5.5 ± 4.9 years. The PDs were compensated for an average of 54.7% (±14.9% SD, 0%-100% range) of their time towards clinical duties. They were compensated on average for 35.7% (±12.6%, 0%-100%) of effort for residency-related administrative duties. Only 5% of PDs had obtained or were enrolled in an education-related degree. Only 55.4% of PDs had received formal surgical education training in teaching and assessment. 54.1% of PDs were interested in obtaining a more senior leadership position in the future. Most PDs (38.4%) expect to serve as PD for 5 to 8 years in total. Overall, the majority of PDs were very satisfied (29.6%) or satisfied (51.6%) professionally; similarly 28.9% were very satisfied and 48.4% satisfied personally.

CONCLUSIONS

This study represents the most up-to-date characterization of the personal, academic, and career-related features of current surgical residency PDs across the US. PDs enjoy a high degree of professional and personal satisfaction and most aspire to increasing leadership within their organizations. Compared to prior data, PDs have become more diverse in terms of both gender and race over time. Opportunities exist for increased mentorship of aspiring and current PDs as well as increased training in teaching and assessment.

Forum Theatre to Address Peer-to-Peer Mistreatment in General Surgery Residency

OBJECTIVE

Mistreatment is widespread in graduate medical education, and much attention has been generated on this topic and its relationship to burnout in general surgery residency. In particular, peer-to-peer mistreatment poses a developmental dilemma - as junior residents find themselves mistreated and some turn around and perpetuate that mistreatment. There is a paucity of effective interventions. Forum Theatre (FT) is a novel educational tool to engage participants in solving difficult situations. We present the use of FT as a tool to explore solutions to address peer-to-peer mistreatment in a surgery residency. FT starts with the performance of a culture-specific conflict scenario and then invites the audience to participate in renditions of the situation ending in a collective solution.

DESIGN

Stakeholder support was obtained from the general surgery program leadership. Time was protected during two 1-hour scheduled wellness didactic sessions. First, focus groups with each PG year identified the residents' experience of mistreatment. Themes regarding peer-to peer mistreatment were identified and presented to a group of 3 volunteer actor residents who chose to focus on the unintended consequences of public, corrective feedback with the understanding this would be presented to the residency at large. Following this, they developed a scenario for enactment which was implemented during the second didactic session. The enacted scenario posed a problem with public feedback ending unsatisfactorily. The audience was then invited to engage the actors and participate in replays of the situation until a collective solution was identified. Retrospective pre-post survey and a 6-month post survey were administered.

SETTING

General surgery residency at University of Texas Health San Antonio.

PARTICIPANTS

General surgery residents. 32 of 66 (48.5%) residents participated.

RESULTS

Participants noted an improved understanding of mistreatment, felt more confident in recognizing mistreatment, reported improved confidence in their ability to intervene when witnessing mistreatment and to recognize when they themselves were involved in mistreatment (p < 0.001 for all). In fact, of the residents who reported participating in mistreatment, 100% reported directing it towards peers. After the FT, 89% of residents said they "definitely" or "most likely" recommended participating in a FT to address mistreatment. 85.7% reported that the intervention was moderately to extremely effective for teaching topics in professionalism. These trends remained steady in the survey 6 months after the intervention as well.

CONCLUSIONS

We found FT was feasible to implement in a busy general surgery residency and well received with sustained, self- reported behavior change. FT is a novel tool to engage residents to self-evaluate and participate in methods to address mistreatment. FT interventions can be tailored to the local culture to address conflicts specific to that setting.

Gender Discrepancies in Middle Author Publications in US Academic General Surgery

INTRODUCTION

To explore gender discrepancies in publications at general surgery departments, we performed a cross-sectional comparing the number of women and men at each academic rank and their number of first author (FA), middle author (MA), last author (LA), and total publications.

METHODS

Thirty academic general surgery departments were randomly selected. For each faculty, we tabulated: first, middle, last names, gender, academic rank, educational leadership, year of medical school graduation, and additional graduate degrees. Bibliography, H-index, and citations were downloaded from the Scopus database.

RESULTS

One thousand three hundred twenty-six faculty sampled, 881 (66.4%) men and 445 (33.5%) women. Men outnumbered women at all ranks, with increasing disparity at higher ranks. Men outnumbered women in all subspecialties-largest difference in transplant surgery (84.4% versus 15.6%, P < 0.001). Men at all ranks had more MA publications: assistant professor (rate ratio 1.20; 95% confidence interval, 1.01-1.43, P = 0.024), associate professor (1.65; 1.31-2.06, P < 0.001), and professor (1.50; 1.20-1.91, P = 0.008). Men associate professors had more LA publications (1.74; 1.34-2.37, P < 0.001). No differences found in FA publications at any rank, nor LA publications at assistant professor and professor ranks. At subspecialty level, men in surgical oncology (1.95; 1.55-2.45, P < 0.001) and transplant surgery (1.70; 1.09-2.66, P = 0.02) had more MA publications.

CONCLUSIONS

While FA and LA publications did not differ significantly across genders, the largest difference lies in MA publications, beginning at junior ranks and persisting with seniority. Discrepancies in MA publications may reflect gender discrepancies in collaborative opportunities, hence total publications should be used cautiously when determining academic productivity.

The Program Director Perspective: Perceptions of PGY5 Residents' Operative Self-Efficacy and Entrustment

INTRODUCTION

A 2020 survey of post-graduate year 5 (PGY5) general surgery residents linked to the American Board of Surgery In-Training Examination (ABSITE) revealed significant deficits in self-efficacy (SE), or personal judgment of one's ability to complete a task, for 10 commonly performed operations. Identifying whether this deficit is similarly perceived by program directors (PDs) has not been well established. We hypothesized that PDs would perceive higher levels of operative SE compared to PGY5s.

METHODS

A survey was distributed through the Association of Program Directors in Surgery listserv; PDs were queried about their PGY5 residents' ability to perform the same 10 operations independently and their accuracy of patient assessments and operative plans for components of several core entrustable professional activities (EPAs). Results of this survey were compared to PGY5 residents' perception of their SE and entrustment based on the 2020 post-ABSITE survey. Chi-squared tests were used for statistical analysis.

RESULTS

108 responses were received, representing ∼32% (108/342) of general surgery programs. Perceptions from PDs of PGY5 residents' operative SE were highly concordant with resident perceptions; no significant differences were observed for 9 of 10 procedures. Both PGY5 residents and PDs perceived adequate levels of entrustment; no significant differences were observed for 6 of 8 EPA components.

CONCLUSIONS

These findings show concordance between PDs and PGY5 residents in their perceptions of operative SE and entrustment. Though both groups perceive adequate levels of entrustment, PDs corroborate the previously described operative SE deficit, illustrating the importance of improved preparation for independent practice.

Society of Black Academic Surgeons (SBAS) diversity, equity, and inclusion series: Microaggressions - Lessons Learned from Black Academic Surgeons

Background:

Microaggressions can target individuals based on a variety of differences and these can include sexual orientation, nationality, gender, or personal traits and are often disruptors in the healthcare setting.

Methods:

To address this issue, The Society of Black Academic Surgeons (SBAS) convened a series of presentations and a panel discussion by leaders from SBAS regarding the issue of microaggressions in the surgical workplace. This program was part of a monthly diversity, equity, and inclusion series produced by the Advances in Surgery Channel in alliance with the American College of Surgeons. Dr. Yewande Alimi addresses microaggressions in surgical training, Dr. Fabian Johnston talks about microaggressions in the black male physician, Dr. Lola Fayanju speaks to microaggressions and the black female surgeon, Dr. Carla Pugh discusses microaggressions in the surgical workplace, and Dr. Paris Butler presents on allyship, policies, and real solutions.

Results:

Specifically, through the lens of the Black surgeon experience, SBAS leaders candidly articulate and elaborate on microaggressions’ pervasiveness and the deleterious impact on the profession. Authentic opinions are rendered and constructive techniques to mitigate this challenge are provided. The concept of majority allyship is also introduced, and recommendations on how this can be operationalized is also examined.

Conclusions:

There are a lot of experiences that contribute to our understanding of microaggressions. We look forward to finding new ways to partner with our allies and continuing the conversation.

The fundamentals of laparoscopic surgery in general surgery residency: fundamental for junior residents' self-efficacy

BACKGROUND

Implementation of the Fundamentals of Laparoscopic Surgery (FLS) by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) has served a need for educational structure for laparoscopic skill within General Surgery training since 2004. This study looks at how FLS affects resident self-efficacy (SE) with laparoscopic procedures.

METHODS

We conducted a national survey, linked to the 2020 American Board of Surgery In-Training Examination (ABSITE), in which 9275 residents from 325 US General Surgery Training Programs participated. The online survey included multimodal questions that analyzed whether participants felt they could perform the most commonly-logged laparoscopic operations among residents [Laparoscopic Appendectomy (LA), Laparoscopic Cholecystectomy (LC), Laparoscopic Right Hemicolectomy (LRH), Diagnostic Laparoscopy (DL)] without faculty assistance. This used a 5-point scaled assessment, ranging from "not able to" to "definitely able to." Multivariate analyses determined if completion of FLS made a difference for resident self-efficacy, stratified by post-graduate year (PGY).

RESULTS

At the time of the survey, 2300 reported completion of FLS. The percentage of FLS completion increased from PGY1 to PGY5 (4.2% n = 59 vs 85.8% n = 893). PGY1 residents who completed FLS, from 48 diverse institutions, demonstrated the most significant increases in SE (p < 0.05) with significantly higher perceived self-efficacy in LA (p = 0.001) and LRH (p = 0.012). PGY2 and PGY3 residents indicated increased SE in DL (p = 0.037, p = 0.015, respectively), based on FLS completion. These FLS effects were less evident in the more senior classes.

CONCLUSIONS

Completion of FLS arguably has the greatest benefits for more junior residents, as it establishes a foundation of laparoscopic knowledge and skill, upon which further residency training can build. Successful completion of the curriculum and assessment offered by the Fundamentals of Laparoscopic Surgery leads to greater sense of ability in early trainees.

Identifying Potential Attrition during the Residency Applicant Screening Process Using a Situational Judgment Test

OBJECTIVE

As USMLE Step 1 moves to pass/fail, residency programs are seeking alternate interview selection processes. Attrition in general surgery is reported as high as 26%. Thus, it is important to ensure that programs are selecting and matching applicants with shared values. Situational judgment tests (SJTs) measure educational and cultural values by posing ambiguous situations and individuals rate the effectiveness of possible reactions. SJTs have previously been shown to identify job applicants with shared values while promoting diversity. Scoring categories are high, moderate, or low values congruence. We sought to explore predictive validity of the SJT relative to program attrition.

DESIGN

Residents who matched into our program between 2018 and 2021 completed the SJT. We tracked attrition.

SETTING

UT Health San Antonio, Texas PARTICIPANTS: Fifty-six categorical general surgery residents RESULTS: Per SJT ratings, the numbers of residents who had high, moderate, and low values congruence were 27, 16, and 13, respectively. Attrition numbers for residents who scored high and moderate congruence were similar, indicating that these ratings were indistinguishable. As such, we combined those 2 categories to create a 2 × 2 matrix and used signal detection theory as a framework for analysis. Overall attrition was 16.1% (9/56). Of the 43 residents who scored high or moderate congruence, 90.7% remained in the program. There was a 9.3% chance of attrition for these residents. Of the 13 residents who scored low congruence, 38.5% attrited. While scoring as low congruence on the SJT does not definitively indicate attrition, it does indicate that attrition is 4.14 times more likely for these residents (chi-square, p = 0.0121).

CONCLUSIONS

One of the most important aspects of residency applicant selection and interviewing is mitigating risk by identifying applicants who carry a high risk of attrition. The SJT significantly identifies at-risk applicants.

Diversity, Equity, and Inclusion: A Current Analysis of General Surgery Residency Programs

BACKGROUND

Local, regional, and national diversity, equity, and inclusion (DEI) initiatives have been established to combat barriers to entry and promote retention in surgery residency programs. Our study evaluates changes in diversity in general surgery residency programs. We hypothesize that diversity trends have remained stable nationally and regionally.

MATERIALS AND METHODS

General surgery residents in all postgraduate years were queried regarding their self-reported sex, race, and ethnicity following the 2020 ABSITE. Residents were then grouped into geographic regions. Data were analyzed utilizing descriptive statistics, Kruskal-Wallis test, and chi-square analyses.

RESULTS

A total of 9276 residents responded. Nationally, increases in female residents were noted from 38.0 to 46.0% (P < .001) and in Hispanic or Latinx residents from 7.3 to 8.3% (P = .031). Across geographic regions, a significant increase in female residents was noted in the Northwest (51.9 to 58.3%, P = .039), Midwest (36.9 to 43.3%, P = .006), and Southwest (35.8 to 47.5%, P = .027). A significant increase in black residents was only noted in the Northwest (0 to 15.8%, P = .031). The proportion of white residents decreased nationally by 8.9% and in the Mid-Atlantic, Southeast, and Southwest between 5.5 and 15.9% (P < .05).

DISCUSSION

In an increasingly diverse society, expanding the numbers of underrepresented surgeons in training, and ultimately in practice, is a necessity. This study shows that there are region-specific increases in diversity, despite minimal change on a national level. This finding may suggest the need for region-specific DEI strategies and initiatives. Future studies will seek to evaluate individual programs with DEI plans and determine if there is a correlation to changing demographics.

American Board of Surgery Entrustable Professional Activities (EPAs): Assessing Graduating Residents' Perception of Preoperative Entrustment

OBJECTIVE

To determine if graduating surgical residents are achieving entrustment of surgical entrustable professional activities (EPAs). We hypothesize that postgraduate year 5 (PGY5) residents are achieving evaluation and management entrustment in the selected EPAs.

DESIGN

In January 2020, surgical residents completed a survey following the American Board of Surgery In-Training Examination (ABSITE) to measure their levels of entrustment in 4 of the 5 ABS-selected EPAs. A Resident Entrustability Index (REI) score was developed to ascertain PGY5 residents' levels of entrustment (range 1-5). Residents indicated how often their assessments and operative plans were modified in the prior 6 months for each EPA (1=Always, 2=Frequently, 3=Occasionally, 4=Rarely, 5=Never). An independent clinical decision-making score (ICDM) was developed with subsequent evaluation of its relationships to intrinsic, resident-related and extrinsic, program-dependent factors.

SETTING

A national post-ABSITE survey.

PARTICIPANTS

All general surgery residents participating in ABSITE were invited to participate. Of the 1367 PGY5 residents that completed the survey, 1049 residents (76.7%) responded to the surgical EPA items.

RESULTS

Residents achieved an average REI of 4, indicating rare modification of assessments and operative plans for the 4 EPAs assessed. Complete entrustment was reported for inguinal hernias and penetrating abdominal trauma (Median REI = 5, IQR 4, 5) indicating assessments and operative plans were never modified. Lack of entrustment (REI ≤3) was reported by a minority of residents (ranging from 8.6% for operative plan of right lower quadrant pathology to 12.8% for operative plan of blunt abdominal trauma). Significant resident-related and program-dependent factors associated with achievement of expected ICDM was socializing with a co-resident (p = 0.001), while training in one's hometown (p < 0.001) and policies that mandate attendings be scrubbed in (p = 0.022) were associated with decreased achievement of expected ICDM. Overall, 89.2% and 90.3% of PGY5 residents are attaining appropriate levels of entrustment and ICDM abilities, respectively, within 6 months of graduating.

CONCLUSIONS

Of the EPAs evaluated, PGY5 residents are achieving appropriate levels of entrustment in evaluation and management. Although this is the case for a vast majority of PGY5 residents, there is still work to be done to ensure that all PGY5 residents are attaining entrustment prior to graduation. Our study also provides content validity for the surgical EPAs in assessing levels of entrustment in PGY5 residents.

Defining the Deficit in US Surgical Training: The Trainee's Perspective

BACKGROUND

Self-efficacy is the personal judgment of how well one can successfully complete a task. The goal of this study was to assess self-efficacy of PGY5 residents for common general surgery operations. We hypothesized there are deficits in self-efficacy of PGY5 residents, and self-efficacy of a given operation correlates with experience performing the operation without attending assistance (independently) and teaching the operation from start to finish.

METHODS

A survey was linked to the 2020 American Board of Surgery In-Training Examination. From the ACGME case log's 15 most commonly performed surgeon-chief operations and AHRQ's 15 most common operations, 10 operations were selected. Residents evaluated their ability to perform these operations independently using a 5-point self-efficacy scale. Residents were asked whether they had experience performing these operations independently or teaching the operation from start to finish. Descriptive statistics and Pearson correlation were used to examine the relationship between self-efficacy and operative experience.

RESULTS

In all, 1,145 of 1,367 PGY5 residents (84%) responded. Highest self-efficacy was in performing wide-local excision (90.24%) and lowest was in performing open thyroidectomy (19.58%). Eighty-eight (7.7%) reported self-efficacy in all procedures. Statistically significant positive correlations were identified between experience and self-efficacy for cases performed without assistance (r = 0.98, p < 0.01) and cases taught (r = 0.91, p < 0.01).

CONCLUSIONS

With 5 months left in training, 92.3% of residents report deficits in preparation for practice, as defined by self-efficacy to complete common procedures independently. Resident self-efficacy increased in direct relation to performed cases and cases taught.

Surgical Inpatient's Attitudes Toward Resident Participation: All About Expectations

OBJECTIVE

Determine whether an educational video can improve surgical inpatients' attitudes toward resident participation in their care.

METHODS

Patients admitted to the Trauma/Emergency General Surgery Service at University Hospital (San Antonio, Texas) were randomly divided into control and intervention groups. Patients in the intervention group viewed a short educational video about the role and responsibilities of medical students, residents, and attending surgeons. All patients then completed a previously published survey.

RESULTS

A total of 140 patients responded to the survey (control = 81 and intervention = 59 patients). Overall, 86.4% of patients were welcoming of resident participation. Patients who were expecting residents to be involved in their care had attitudes that are more favorable on almost all survey questions regardless of their study condition. However, patients in the intervention group who expected resident involvement in their care had more favorable attitudes about senior residents (postgraduate year 3-5) assisting in routine or complicated surgery than those in the control group who were expecting resident involvement (both p ≤ 0.001). This same group of patients also had more favorable attitudes about surgical outcomes and overall surgical health when residents are involved (p = 0.004, p = 0.001, respectively). Most patients (79%) said they had no residents previously involved in their care, or they were unsure if residents were previously involved.

CONCLUSIONS

Patient expectation of resident involvement is one of the most important factors influencing perceptions of inpatients about resident participation in surgery. Our goal should be early and frequent discussion with patients about resident involvement in order to foster an atmosphere of trust, including full transparency regarding resident involvement in surgical procedures. An educational video may help introduce the roles of trainees and attending surgeons but should not be used in lieu of direct discussion with patients.

Surgery Program Director Turnover Correlates With Residency Graduate Failure on American Board of Surgery Examinations in Civilian Residency Programs

PURPOSE

The Review Committee for Surgery requires a minimum program director (PD) tenure of 6 years. The impact of PD turnover on the performance of program graduates is unknown. We hypothesize that (1) the majority of PDs step down before 6-year tenure and (2) higher PD turnover is associated with higher failure rate on American Board of Surgery (ABS) examinations.

METHODS

Start and stop dates of all surgery PDs between January 1, 2000 and December 31, 2017 were obtained for civilian surgery programs. A Kaplan-Meier curve of PD "survival" was constructed. Programs were divided into High Turnover (HT; ≥4 PD changes, n = 33) and Low Turnover (LT; ≤3 PD changes, n = 191) groups. Five-year (2013-2017) ABS pass rates were also obtained. Pass rates and compliance with current standards were compared between groups.

RESULTS

Kaplan-Meier analysis revealed that 40% of PDs do not comply with ACGME policy and serve <6 years. HT programs had lower mean pass rates on ABS certifying exam than LT programs (76% vs 83%, p < 0.01), but not qualifying exam (88% vs 88%). HT programs are less likely to meet the current 65% pass rate standard (82% vs 93%, p < 0.05).

CONCLUSIONS

(1) An estimated 40% of general surgery PDs had tenures of <6 years. (2) Greater PD turnover is associated with lower ABS pass rates among general surgery graduates.

Survival After a Transcranial Bihemispheric Stabbing with a Knife: Case Report and Literature Review

Low-velocity penetrating brain injuries (PBIs), also referred to as nonmissile brain injuries, typically result from stabbings, industrial or home accidents, or suicide attempts. A great deal of literature has focused on the injury patterns and management strategies of high-velocity PBIs. However, there are substantially fewer large, contemporary studies focused solely on low-velocity PBIs. Here, we present an interesting and uncommon case of a patient who suffered a bihemispheric stab wound involving the basal ganglia. A 22-year-old man presented to the hospital with a stab wound to the left calvarium. His initial Glasgow Coma Scale (GCS) score was 13, but he rapidly declined to a six and was intubated. He was emergently taken to the operating room for craniectomy, knife removal, and external ventricular drain placement. On the first postoperative day, the patient was following commands with all extremities. He was discharged to a rehabilitation facility 13 days postinjury. One year after the injury, the patient was free of major neurologic sequelae. This report illustrates a rare case of a good functional outcome after a transcranial stabbing with multiple imaging and exam findings usually associated with poor outcomes.

Femoral Head Dislocation into the Rectum Following Blunt Trauma

Traumatic hip dislocations require prompt diagnosis and treatment to prevent avascular necrosis of the femoral head. This injury is further complicated when there is an ipsilateral femur fracture. Here, we present what is likely the first reported case of a patient with traumatic hip dislocation and ipsilateral femur fracture with transrectal displacement of the femoral head. The patient presented to a level one trauma center in 2006 as a transfer from another facility after being thrown from a pickup truck. Upon initial evaluation, a foreign body was palpated in the rectum. Computed tomography (CT) imaging showed that the right femoral head was lodged within the pelvis. In the operating room, an exploratory laparotomy was performed, and anoscopy confirmed the placement of the femoral head within the rectal lumen. The femoral head was extracted from the rectum transanally. The operation was abbreviated, as the patient became hemodynamically unstable, and he was taken to the intensive care unit. He returned to the operating room the following day for a repeat washout and proximal diversion. Despite numerous orthopedic procedures and operative washouts, he ultimately underwent a right hip disarticulation. Physicians should be aware that intracorporeal femoral head displacement is possible in select patients who have experienced a high-energy trauma mechanism. This is a complicated, highly morbid injury that poses various management challenges to orthopedic and acute care surgeons.

Mass shootings: Are children safer in the streets than in the home?

PURPOSE

Though the total fatality and injury count in mass shootings is known, the burden on the pediatric population remains undefined. We sought to define the impact of domestic vs. public mass shootings in the pediatric population.

METHODS

Open-source databases, Everytown for Gun Violence, and Mother Jones were cross-referenced and used to review domestic and public mass shootings from 2009 to 2016. Mass shootings were defined as four or more fatalities and any injuries. Domestic mass shootings were defined as ones that occurred in the home where the assailant was either a family member or a past or present intimate partner of a family member. Public mass shootings occurred in a public space where the shooter was unknown to the victim. The number of incidents in each group, fatalities and injuries, and effect on children <18 years were analyzed along with perpetrator characteristics. Categorical data were analyzed using Fisher's Exact test.

RESULTS

There were 71 Domestic and 31 Public mass shootings accounting for 331 vs. 281 fatalities and 28 vs. 217 injuries (p < 0.0001). Children <18 years accounted for 44% of Domestic and 10% of Public fatalities (p < 0.0001) and 46% vs. 2% of all injuries (p < 0.0001). The assailant was prohibited from owning or possessing a firearm in 32% of Domestic and 39% of Public mass shootings accounting for 54 vs. 25 fatalities.

CONCLUSION

The pediatric fatality rate in mass shootings is alarming, especially among Domestic shooting events. This is a public health issue and requires vigilance to protect at-risk youth.

Evolution of a Novel Business Leadership Course for General Surgery Chief Residents

Background

General surgery chief residents are typically well equipped for board examinations but poorly trained to deal with the business challenges of surgical practice. We began a business leadership course to better prepare them for their careers.

Methods

Chief residents were given one-hour lectures with topics that included: Differences between private/academic practice, personal finances, contracts, practice management, legal issues and health law, and time management.

Results

Initial evaluations revealed that the topics covered and the presentations were well received. Subsequently, the course was moved to earlier in the academic year to prepare them for contract negotiations and then to Sunday nights to decrease interruptions and allow spouse participation.

Conclusions

The course evolved into a program that the chief residents feel is an important addition to their education. Moving the meetings to a weekend evening improved attendance, decreased interruptions, and allowed participation by spouses and significant others.

Video-Based Patient Education Improves Patient Attitudes Toward Resident Participation in Outpatient Surgical Care

OBJECTIVE

Decipher if patient attitudes toward resident participation in surgical care can be improved with patient education using a video-based modality.

DESIGN

A survey using a 5-pt Likert scale was created, piloted, and distributed in general and colorectal surgery outpatient clinics that had residents involved with patient care at 2 facilities, both with control and intervention groups. The intervention group viewed a short video (∼4 min) explaining the role, education, and responsibilities of medical students, residents, and attending surgeons prior to answering the survey.

SETTING

General and colorectal surgery outpatient clinics at the University of Texas Health San Antonio, Texas.

PARTICIPANTS

A total of 383 responses were collected, all clinic patients were eligible.

RESULTS

The majority of patients (82%) welcomed resident participation in their health care. Eighteen percent of patients did not expect residents to be involved in their care. Patients had favorable views of residents participating during their surgical procedures with 77% responding "agree" or "strongly agree" to a senior resident assisting with a complicated procedure. Patients who viewed the video versus control were less concerned with how much of the procedure the resident would perform (76% vs 86%, p = 0.010). Patients who viewed the video felt less inconvenienced (p = 0.004).

CONCLUSIONS

The majority of patients are welcoming to resident participation in their surgical care but only 54% were expecting resident involvement at their clinic visit. Early explanation with an educational video of resident roles, education, and responsibilities may help bridge the gap and improve patient experience.

Failure on the American Board of Surgery Examinations of General Surgery Residency Graduates Correlates Positively with States’ Malpractice Risk

It has been suggested that in environments where there is greater fear of litigation, resident autonomy and education is compromised. Our aim was to examine failure rates on American Board of Surgery (ABS) examinations in comparison with medical malpractice payments in 47 US states/ territories that have general surgery residency programs. We hypothesized higher ABS examination failure rates for general surgery residents who graduate from residencies in states with higher malpractice risk. We conducted a retrospective review of five-year (2010–2014) pass rates of first-time examinees of the ABS examinations. States’ malpractice data were adjusted based on population. ABS examinations failure rates for programs in states with above and below median malpractice payments per capita were 31 and 24 per cent ( P < 0.01) respectively. This difference was seen in university and independent programs regardless of size. Pearson correlation confirmed a significant positive correlation between board failure rates and malpractice payments per capita for Qualifying Examination ( P < 0.02), Certifying Examination ( P < 0.02), and Qualifying and Certifying combined index ( P < 0.01). Malpractice risk correlates positively with graduates’ failure rates on ABS examinations regardless of program size or type. We encourage further examination of training environments and their relationship to surgical residency graduate performance.

Association of General Surgery Resident Remediation and Program Director Attitudes With Resident Attrition

Importance

Previous studies of resident attrition have variably included preliminary residents and likely overestimated categorical resident attrition. Whether program director attitudes affect attrition has been unclear.

Objectives

To determine whether program director attitudes are associated with resident attrition and to measure the categorical resident attrition rate.

Design, Setting, and Participants

This multicenter study surveyed 21 US program directors in general surgery about their opinions regarding resident education and attrition. Data on total resident complement, demographic information, and annual attrition were collected from the program directors for the study period of July 1, 2010, to June 30, 2015. The general surgery programs were chosen on the basis of their geographic location, previous collaboration with some coauthors, prior work in surgical education and research, or a program director willing to participate. Only categorical surgical residents were included in the study; thus, program directors were specifically instructed to exclude any preliminary residents in their responses.

Main Outcomes and Measures

Five-year attrition rates (2010-2011 to 2014-2015 academic years) as well as first-time pass rates on the General Surgery Qualifying Examination and General Surgery Certifying Examination of the American Board of Surgery (ABS) were collected. High- and low-attrition programs were compared.

Results

The 21 programs represented different geographic locations and 12 university-based, 3 university-affiliated, and 6 independent program types. Programs had a median (interquartile range [IQR]) number of 30 (20-48) categorical residents, and few of those residents were women (median [IQR], 12 [5-17]). Overall, 85 of 966 residents (8.8%) left training during the study period: 15 (17.6%) left after postgraduate year 1, 34 (40.0%) after postgraduate year 2, and 36 (42.4%) after postgraduate year 3 or later. Forty-four residents (51.8%) left general surgery for another surgical discipline, 21 (24.7%) transferred to a different surgery program, and 18 (21.2%) exited graduate medical education altogether. Each program had an annual attrition rate ranging from 0.73% to 6.0% (median [IQR], 2.5% [1.5%-3.4%]). Low-attrition programs were more likely than high-attrition programs to use resident remediation (21.0% vs 6.8%; P < .001). Median (IQR) Qualifying Examination pass rates (93% [90%-98%] vs 92% [86%-100%]; P = .92) and Certifying Examination pass rates (83% [68%-84%] vs 81% [71%-86%]; P = .47) were similar. Program directors at high-attrition programs were more likely than their counterparts at low-attrition programs to agree with this statement: "I feel that it is my responsibility as a program director to redirect residents who should not be surgeons."

Conclusions and Relevance

The overall 5-year attrition rate of 8.8% was significantly lower than previously reported. Program directors at low-attrition programs were more likely to use resident remediation. Variations in attrition may be explained by program director attitudes, although larger studies are needed to further define program factors affecting attrition.

Immediate Auditory Feedback is Superior to Other Types of Feedback for Basic Surgical Skills Acquisition

OBJECTIVE

We examined the effect of timing and type of feedback on medical students' knot-tying performance using visual versus auditory and immediate versus delayed feedback. We hypothesized that participants who received immediate auditory feedback would outperform those who received delayed and visual feedback.

METHODS

Sixty-nine first- and second-year medical students were taught to tie 2-handed knots. All participants completed 3 pretest knot-tying trials without feedback. Participants were instructed to tie a knot sufficiently tight to stop the "blood" flow while minimizing the amount of force applied to the vessel. Task completion time was not a criterion. Participants were stratified and randomly assigned to 5 experimental groups based on type (auditory versus visual) and timing (immediate versus delayed) of feedback. The control group did not receive feedback. All groups trained to proficiency. Participants completed 3 posttest trials without feedback.

RESULTS

There were fewer trials with leak (p < 0.01) and less force applied (p < 0.01) on the posttest compared to the pretest, regardless of study group. The immediate auditory feedback group required fewer trials to achieve proficiency than each of the other groups (p < 0.01) and had fewer leaks than the control, delayed auditory, and delayed visual groups (p < 0.02).

CONCLUSIONS

In a surgical force feedback simulation model, immediate auditory feedback resulted in fewer training trials to reach proficiency and fewer leaks compared to visual and delayed forms of feedback.

Tools for Assessment of Communication Skills of Hospital Action Teams: A Systematic Review

BACKGROUND

Hospital action teams comprise interdisciplinary health care providers working simultaneously to treat critically ill patients. Assessments designed to evaluate communication effectiveness or "nontechnical" performance of these teams are essential to minimize medical errors and improve team productivity. Although multiple communication tools are available, the characteristics and psychometric validity of these instruments have yet to be systematically compared.

OBJECTIVE

To identify assessments used to evaluate the communication or "nontechnical" performance of hospital action teams and summarize evidence to develop and validate these instruments.

METHOD

A literature search was conducted using MEDLINE/PubMed database to identify original articles related to assessment of communication skills in teams working in acute care medicine not exclusive to emergency room, operating room, prehospital air and ground transport, or code blue/rapid response resuscitations.

RESULTS

Ten communication assessment tools were identified. Six tools (60%) were designed to measure communication performance of the whole team, whereas 4 tools (40%) were created to assess individual team member's communication skills. Regardless of the type of analysis, the most commonly assessed behavior domains were Leadership, Teamwork, Communication, and Situation awareness. Only 1 of 16 articles describing a particular communication assessment tool reported all the validation criteria, other authors underreported efforts to validate their instruments.

CONCLUSION

A number of tools designed to measure the communication or "nontechnical" performance of hospital action teams are available. Unfortunately, limited reported validity evidence may hamper the utility of these tools in actual clinical practice until further validation studies are performed.

Mass Casualty Incident Management Preparedness: A Survey of the American College of Surgeons Committee on Trauma

Mass casualty incidents (MCIs) are events resulting in more injured patients than hospital systems can handle with standard protocols. Several studies have assessed hospital preparedness during MCIs. However, physicians and trauma surgeons need to be familiar with their hospital's MCI Plan. The purpose of this survey was to assess hospitals' and trauma surgeon's preparedness for MCIs. Online surveys were e-mailed to members of the American College of Surgeons committee on Trauma Ad Hoc Committee on Disaster and Mass Casualty Management before the March 2012 meeting. Eighty surveys were analyzed (of 258). About 76 per cent were American College of Surgeons Level I trauma centers, 18 per cent were Level II trauma centers. Fifty-seven per cent of Level I and 21 per cent of Level II trauma centers had experienced an MCI. A total of 98 per cent of respondents thought it was likely their hospital would see a future MCI. Severe weather storm was the most likely event (95%), followed by public transportation incident (86%), then explosion (85%). About 83 per cent of hospitals had mechanisms to request additional physician/surgeons, and 80 per cent reported plans for operative triage. The majority of trauma surgeons felt prepared for an MCI and believed an event was likely to occur in the future. The survey was limited by the highly select group of respondents and future surveys will be necessary.

Professionalism in the Twilight Zone: A Multicenter, Mixed-Methods Study of Shift Transition Dynamics in Surgical Residencies

PURPOSE

Duty hours rules sparked debates about professionalism. This study explores whether and why general surgery residents delay departures at the end of a day shift in ways consistent with shift work, traditional professionalism, or a new professionalism.

METHOD

Questionnaires were administered to categorical residents in 13 general surgery programs in 2014 and 2015. The response rate was 76% (N = 291). The 18 items focused on end-of-shift behaviors and the frequency and source of delayed departures. Follow-up interviews (N = 39) examined motives for delayed departures. The results include means, percentages, and representative quotations from the interviews.

RESULTS

A minority (33%) agreed that it is routine and acceptable to pass work to night teams, whereas a strong majority (81%) believed that residents exceed work hours in the name of professionalism. Delayed departures were ubiquitous: Only 2 of 291 residents were not delayed for any of 13 reasons during a typical week. The single most common source of delay involved a desire to avoid the appearance of dumping work on fellow residents. In the interviews, residents expressed a strong reluctance to pass work to an on-call resident or night team because of sparse night staffing, patient ownership, an aversion to dumping, and the fear of being seen as inefficient.

CONCLUSIONS

Resident behavior is shaped by organizational and cultural contexts that require attention and reform. The evidence points to the stunted development of a new professionalism, little role for shift-work mentalities, and uneven expression of traditional professionalism in resident behavior.

The Effect of Patient Education on the Perceptions of Resident Participation in Surgical Care

OBJECTIVE

To decipher if patient attitudes toward resident participation in their surgical care can be improved with patient education regarding resident roles, education, and responsibilities.

DESIGN

An anonymous questionnaire was created and distributed in outpatient surgery clinics that had residents involved with patient care. In total, 3 groups of patients were surveyed, a control group and 2 intervention groups. Each intervention group was given an informational pamphlet explaining the role, education, and responsibilities of residents. The first pamphlet used an analogy-based explanation. The second pamphlet used literature citations and statistics.

SETTING

Keesler Medical Center, Keesler AFB, MS. University of Texas Health Science Center at San Antonio, San Antonio, TX.

PARTICIPANTS

A total of 454 responses were collected and analyzed-211 in the control group, 118 in the analogy pamphlet group, and 125 in the statistics pamphlet group.

RESULTS

Patients had favorable views of residents assisting with their surgical procedures, and the majority felt that outcomes were the same or better regardless of whether they read an informational pamphlet. Of all the patients surveyed, 80% agreed or strongly agreed that they expect to be asked permission for residents to be involved in their care. Further, 52% of patients in the control group agreed or strongly agreed to a fifth-year surgery resident operating on them independently for routine procedures compared to 62% and 65% of the patients who read the analogy pamphlet and statistics pamphlet, respectively (p = 0.05). When we combined the 2 intervention groups compared to the control group, this significant difference persisted (p = 0.02).

CONCLUSION

Most patients welcome resident participation in their surgical care, but they expect to be asked permission for resident involvement. Patient education using an information pamphlet describing resident roles, education, and responsibilities improved patient willingness to allow a chief resident to operate independently.

Predicting Success of Preliminary Surgical Residents: A Multi-Institutional Study

OBJECTIVE

A nondesignated preliminary surgery (NDPS) position encompasses 1 year of training provided by many general surgery residencies. Our aim was to assess factors predicting success and provide evidence for program directors to support career guidance to preliminary residents.

METHODS

Retrospective cohort study of 221 NDPS residents who entered 5 university-based institutions were identified from 2009 to 2013. Records for trainees were reviewed. We defined primary success as obtaining a categorical position in the specialty of choice and secondary success as obtaining a categorical position in any specialty immediately after finishing their NDPS training. Statistical evaluation was performed using chi-square analysis, independent t-test and logistic regression using α <0.05.

RESULTS

Of the 221 NDPS residents, 217 (98%) completed postgraduate year (PGY)-1 and 65 (29%) completed PGY-2. Totally, 90 (41%) obtained categorical general surgery positions, 89 (40%) obtained categorical positions in other specialties, and 42 (19%) failed to obtain a categorical position immediately after their NDPS years. Ultimately, 139 (63%) of residents achieved primary success and 40 (18%) additional residents obtained categorical positions in specialties other than their first choice, resulting in a total of 179 (81%) of residents obtaining categorical positions. Mean United States Medical Licensing Examination step 1 and step 2 scores for those who obtained secondary success were 227 and 234 vs. 214 and 219, respectively, for those who failed to secure a categorical position (p < 0.01). United States Medical Licensing Examination step 2 score was a significant predictor of primary (p < 0.03) and secondary success (p < 0.02). Of 65 PGY-2 NDPS residents, 32 (49%) achieved primary success, and 11 (17%) others achieved secondary success for a total of 43 (66%). For PGY-2 NDPS, American Board of Surgery In-Training Examination was the only significant predictor of primary and secondary success (p < 0.02 and p < 0.05).

CONCLUSIONS

NDPS training provides a viable and successful opportunity for at least 81% of young physicians to pursue their career goals even after an unsuccessful first match.

Small Bowel Perforations by Metallic Grill Brush Bristles: Clinical Presentations and Opportunity for Prevention

Increasing reports on the incidental ingestion of metallic bristles from barbeque grill cleaning brushes have been reported. We sought to describe the clinical presentation and grilling habits of patients presenting after ingesting metallic bristles in an attempt to identify risk factors. We performed a chart review of six patients with documented enteric injury from metallic bristles. Subjects were contacted and administered a survey focused on the events surrounding the bristle ingestion. We arranged for in-home visits to inspect the grill and grill brush whenever possible. Of the six subjects identified, three (50%) were male, five (83%) were white, and they ranged in age from 18 to 65 years (mean 42.5). All complained of abdominal pain. All bristles were identified by CT scan. Three patients underwent laparoscopic enterorrhaphy, and two underwent laparotomy. The remaining patients did not require intervention. None had replaced their grill brush in at least two years. Surgeon's awareness of this unusual injury is important to identify and manage this problem. Alternative methods to clean the grill should be sought and grill brushes should be replaced at least every two years.

Obesity Is Not Associated with Antimicrobial Treatment Failure for Intra-Abdominal Infection

BACKGROUND

Obesity and commonly associated comorbidities are known risk factors for the development of infections. However, the intensity and duration of antimicrobial treatment are rarely conditioned on body mass index (BMI). In particular, the influence of obesity on failure of antimicrobial treatment for intra-abdominal infection (IAI) remains unknown. We hypothesized that obesity is associated with recurrent infectious complications in patients treated for IAI.

METHODS

Five hundred eighteen patients randomized to treatment in the Surgical Infection Society Study to Optimize Peritoneal Infection Therapy (STOP-IT) trial were evaluated. Patients were stratified by obese (BMI ≥30) versus non-obese (BMI≥30) status. Descriptive comparisons were performed using Chi-square test, Fisher exact test, or Wilcoxon rank-sum tests as appropriate. Multivariable logistic regression using a priori selected variables was performed to assess the independent association between obesity and treatment failure in patients with IAI.

RESULTS

Overall, 198 (38.3%) of patients were obese (BMI ≥30) versus 319 (61.7%) who were non-obese. Mean antibiotic d and total hospital d were similar between both groups. Unadjusted outcomes of surgical site infection (9.1% vs. 6.9%, p = 0.36), recurrent intra-abdominal infection (16.2% vs. 13.8, p = 0.46), death (1.0% vs. 0.9%, p = 1.0), and a composite of all complications (25.3% vs. 19.8%, p = 0.14) were also similar between both groups. After controlling for appropriate demographics, comorbidities, severity of illness, treatment group, and duration of antimicrobial therapy, obesity was not independently associated with treatment failure (c-statistic: 0.64).

CONCLUSIONS

Obesity is not associated with antimicrobial treatment failure among patients with IAI. These results suggest that obesity may not independently influence the need for longer duration of antimicrobial therapy in treatment of IAI versus non-obese patients.

Predicting and enhancing American Board of Surgery In-Training Examination performance: does writing questions really help?

BACKGROUND

The generative learning model posits that individuals remember content they have generated better than materials created by others. The goals of this study were to evaluate question generation as a study method for the American Board of Surgery In-Training Examination (ABSITE) and determine whether practice test scores and other data predict ABSITE performance.

METHODS

Residents (n = 206) from 6 general surgery programs were randomly assigned to one of the two study conditions. One group wrote questions for practice examinations. All residents took 2 practice examinations.

RESULTS

There was not a significant effect of writing questions on ABSITE score. Practice test scores, United States Medical Licensing Examination Step 1 scores, and previous ABSITE scores were significantly correlated with ABSITE performance.

CONCLUSIONS

The generative learning model was not supported. Performance on practice tests and other data can be used for early identification of residents at risk of performing poorly on the ABSITE.

Trial of short-course antimicrobial therapy for intraabdominal infection

BACKGROUND

The successful treatment of intraabdominal infection requires a combination of anatomical source control and antibiotics. The appropriate duration of antimicrobial therapy remains unclear.

METHODS

We randomly assigned 518 patients with complicated intraabdominal infection and adequate source control to receive antibiotics until 2 days after the resolution of fever, leukocytosis, and ileus, with a maximum of 10 days of therapy (control group), or to receive a fixed course of antibiotics (experimental group) for 4±1 calendar days. The primary outcome was a composite of surgical-site infection, recurrent intraabdominal infection, or death within 30 days after the index source-control procedure, according to treatment group. Secondary outcomes included the duration of therapy and rates of subsequent infections.

RESULTS

Surgical-site infection, recurrent intraabdominal infection, or death occurred in 56 of 257 patients in the experimental group (21.8%), as compared with 58 of 260 patients in the control group (22.3%) (absolute difference, -0.5 percentage point; 95% confidence interval [CI], -7.0 to 8.0; P=0.92). The median duration of antibiotic therapy was 4.0 days (interquartile range, 4.0 to 5.0) in the experimental group, as compared with 8.0 days (interquartile range, 5.0 to 10.0) in the control group (absolute difference, -4.0 days; 95% CI, -4.7 to -3.3; P<0.001). No significant between-group differences were found in the individual rates of the components of the primary outcome or in other secondary outcomes.

CONCLUSIONS

In patients with intraabdominal infections who had undergone an adequate source-control procedure, the outcomes after fixed-duration antibiotic therapy (approximately 4 days) were similar to those after a longer course of antibiotics (approximately 8 days) that extended until after the resolution of physiological abnormalities. (Funded by the National Institutes of Health; STOP-IT ClinicalTrials.gov number, NCT00657566.).

Endpoints of resuscitation

Despite the multiple causes of the shock state, all causes possess the common abnormality of oxygen supply not meeting tissue metabolic demands. Compensatory mechanisms may mask the severity of hypoxemia and hypoperfusion, since catecholamines and extracellular fluid shifts initially compensate for the physiologic derangements associated with patients in shock. Despite the achievement of normal physiologic parameters after resuscitation, significant metabolic acidosis may continue to be present in the tissues, as evidenced by increased lactate levels and metabolic acidosis. This review discusses the major endpoints of resuscitation in clinical use.

Performance on brief practice examination identifies residents at risk for poor ABSITE and ABS qualifying examination performance

OBJECTIVE

Performance on the American Board of Surgery (ABS) Qualifying Exam (QE) correlates well with chief resident American Board of Surgery In-Training Exam (ABSITE) scores. Yearly ABSITE performance is a useful gauge of resident fund of knowledge and can identify residents at risk of QE failure. We hypothesize that a brief practice exam administered 1-3 times each academic year can identify residents at risk of poor ABSITE performance and also identify early in the chief resident year those at risk for poor QE performance.

METHODS

In 2005 we began administering 2-3 times/year an approximately 50 question exam consisting of questions authored by residents and edited by faculty based on the ABSITE exam keywords. The exam was considered mandatory and educational time was allotted. Data were analyzed by determining an individual's score deviation from the mean within PGY class. The standard deviation was then compared to the corresponding years ABSITE percentile and in the final year, QE performance using the Spearman rank correlation test.

RESULTS

A total of 710 individual practice exams were offered and 462 (65.1%) were completed in 9 sessions. Two hundred sixty-three residents completed both a practice examination and ABSITE in the year preceding the administration of the ABSITE. Twenty-six chief residents completed a practice examination in the year immediately preceding the ABS QE. Correlations between practice exam scores and ABSITE score percentile were statistically significant (p= 0.01-0.05) for each year the test was administered. The correlation between the practice exam score for chief residents preceding the QE and first attempt QE score was also significant (r =0.416, p<0.05).

CONCLUSIONS

A resident's performance on a brief practice exam administered throughout the year is significantly correlated with both ABSITE performance and ABS QE performance. Such a test can be a useful adjunct for identifying residents at risk for poor ABSITE performance as well as identify prior to return of ABSITE scores those residents at risk for poor ABS QE performance.

Time and degree of glycemic derangement are associated with increased mortality in trauma patients in the setting of tight glycemic control

BACKGROUND

Tight glucose control (TGC) may reduce mortality in critically ill trauma patients. We hypothesize that euglycemia is beneficial, and a measure considering time and degree of hyperglycemia is most associated with mortality.

METHODS

We performed a review of intensive care unit trauma patients admitted for more than 3 days between January 2005 and December 2007 on a TGC protocol with a goal of 80 to 110 mg/dL. Hyperglycemic, hypoglycemic, and euglycemic time ranges, and area of interpolated curves above and below 80 to 110 mg/dL were assessed. Associations with mortality were based on logistic regression models adjusted for age, injury severity score, and admission Glasgow Coma Scale score.

RESULTS

A total of 546 patients were identified, and 68 (13%) died. Time spent as hyperglycemic (P = .29) and hyperglycemic area under the curve (P = .58) were not associated with mortality; hyperglycemic area/time (P = .01) was associated with mortality. Regarding hypoglycemia, area over the curve (P = .009) and time spent as hypoglycemic (P = .002) were associated with mortality.

CONCLUSIONS

TGC prevents prolonged, high degrees of hyperglycemia; avoiding hypoglycemia likely provides mortality benefit for trauma patients.

Recurrent skin and soft tissue infections due to methicillin-resistant Staphylococcus aureus requiring operative debridement

BACKGROUND

The aim of this study was to examine clinical factors associated with the recurrence of community-onset skin and soft tissue infections caused by methicillin-resistant Staphylococcus aureus.

METHODS

An observational case-comparison study based on a retrospective review of medical records was conducted in a public health system. All patients with community-onset skin and soft tissue infections caused by methicillin-resistant S aureus who underwent operative debridement from January 1999 to December 2003 were included. The outcome of interest was recurrence within 1 year.

RESULTS

Two hundred fifty-three patients met the criteria for inclusion. Fifty-three (21%) patients returned with recurrent episodes. These patients were compared with 200 patients (79%) who did not develop recurrence. On multivariate analysis, factors independently predictive of recurrence were medical history of abscess requiring surgical debridement within the previous year (adjusted odds ratio, 2.6; 95% confidence interval, 1.4-5.0; P = .002) and obesity (adjusted odds ratio, 3.4; 95% confidence interval, 1.4-8.8; P = .008).

CONCLUSIONS

Patients with obesity or histories of methicillin-resistant S aureus infection are at significantly increased risk for recurrent soft tissue infection.

Diaphragmatic Injuries: What Has Changed over a 20-Year Period?

Traumatic diaphragmatic injuries are uncommon events but are associated with a high mortality. We hypothesize that injury pattern has changed over time with increasing prevalence of blunt injuries. A retrospective chart review was performed of 124 patients who sustained traumatic diaphragmatic injuries over the 20-year period between January 1,1986 and December 31, 2005. Penetrating trauma accounted for 65 per cent (80/124) of all diaphragm injuries, and blunt trauma for 35 per cent (44/124). Mean Injury Severity Scores of 19 ± 9 and 34 ± 13 were observed for the penetrating and blunt trauma groups, respectively ( P = 0.001). Blunt traumatic diaphragm injuries increased from 13 per cent in the first 10-year period to 66 per cent in the second 10-year period ( P = 0.001). The overall mortality was 9 per cent (11/124) with 10 deaths resulting from blunt trauma and one resulting from penetrating trauma ( P < 0.001). The mortality rate increased from 3 to 17 per cent over the two decades ( P = 0.007). Our data suggests that over the last 20 years, the increase in mortality associated with traumatic diaphragmatic injury is primarily related to an increase in the proportion of patients with blunt trauma as a cause of their diaphragmatic injury and associated injuries.
