Effectiveness of the Surgery Core Clerkship Flipped Classroom: a prospective cohort trial.

BACKGROUND The flipped classroom has been proposed as an alternative curricular approach to traditional didactic lectures but has not been previously applied to a surgery clerkship. METHODS A 1-year prospective cohort of students (n = 89) enrolled in the surgery clerkship was taught using a flipped classroom approach. A historical cohort of students (n = 92) taught with a traditional lecture curriculum was used for comparison. Pretest and post-test performance, end-of-clerkship surveys, and National Board of Medical Examiners (NBME) scores were analyzed to assess effectiveness. RESULTS Mean pretest and post-test scores increased across all modules (P < .001). There was no difference between mean NBME examination score in the prospective and historical cohorts (74.75 vs 75.74, P = .28). Mean ratings of career interest in surgery increased after curriculum completion (4.75 to 6.50, P < .001), with 90% reporting that the flipped classroom contributed to this increase. CONCLUSIONS Implementation of a flipped classroom in the surgery clerkship is feasible and results in high learner satisfaction, effective knowledge acquisition, and increased career interest in surgery with noninferior NBME performance.

Validity evidence for Surgical Improvement of Clinical Knowledge Ops: a novel gaming platform to assess surgical decision making

BACKGROUND Current surgical education curricula focus mainly on the acquisition of technical skill rather than clinical and operative judgment. SICKO (Surgical Improvement of Clinical Knowledge Ops) is a novel gaming platform developed to address this critical need. A pilot study was performed to collect validity evidence for SICKO as an assessment for surgical decision making. METHODS Forty-nine subjects stratified into 4 levels of expertise were recruited to play SICKO. Later, players were surveyed regarding the realism of the gaming platform as well as the clinical competencies required of them while playing SICKO. RESULTS Each group of increasing expertise outperformed the less experienced groups. Mean total game scores for the novice, junior resident, senior resident, and expert groups were 5,461, 8,519, 11,404, and 13,913, respectively (P = .001). Survey results revealed high scores for realism and content. CONCLUSIONS SICKO holds the potential to be not only an engaging and immersive educational tool, but also a valid assessment in the armamentarium of surgical educators.

The Assessment of Emotional Intelligence Among Candidates Interviewing for General Surgery Residency

BACKGROUND There is an increasing demand for physicians to possess strong personal and social qualities embodied in the concept of emotional intelligence (EI). However, the residency selection process emphasizes mainly academic accomplishments. In this system, the faculty interview is the primary means of evaluating the nontangible, nonacademic attributes of a candidate. OBJECTIVE To determine whether the impressions derived from faculty interviews correlate with an applicants actual EI as measured by a validated objective instrument. STUDY DESIGN Participating applicants interviewing for a surgical residency position at Stanford completed an EI inventory Trait Emotional Intelligence Questionnaire (TEIQue). Faculty estimated the EI of the applicants they interviewed using a corresponding 360° evaluation form. Multivariate linear regression was performed to identify demographic and academic factors predictive of EI. Applicant TEIQue scores and faculty 360° impressions were correlated using Pearson coefficients. RESULTS Mean EI of the cohort was higher than that of the average population (5.43 vs 4.89, p<0.001). Age was the only demographic variable that significantly informed EI (B = 0.07, p = 0.005). Among the academic factors considered, United States Medical Licensing Examination Step 1 score was a slight negative predictor of EI (B =-0.007, p = 0.04). Applicant global EI scores did not correlate with faculty impressions of overall EI (r = 0.27, p = 0.06). Of the 4 domains that comprise global EI, sociability and emotionality demonstrated a moderate correlation between applicant and faculty scores (r = 0.31, p = 0.03 and r = 0.27, p = 0.05, respectively). None of the fifteen individual facets of EI demonstrated any correlation between applicant and faculty ratings (r =-0.12 to 0.26, p = 0.06-0.91). No association was found between applicant TEIQue and traditional faculty interview evaluations (r = 0.18, p = 0.19). CONCLUSIONS Applicant EI correlated poorly with academic parameters and was not accurately assessed by faculty interviews. Methods that better capture this dimension should be incorporated into the residency selection process.

The Effect of Positive and Negative Verbal Feedback on Surgical Skills Performance and Motivation

There is considerable effort and time invested in providing feedback to medical students and residents during their time in training. However, little effort has been made to measure the effects of positive and negative verbal feedback on skills performance and motivation to learn and practice. To probe these questions, first-year medical students (n = 25) were recruited to perform a peg transfer task on Fundamentals of Laparoscopic Surgery box trainers. Time to completion and number of errors were recorded. The students were then randomized to receive either positive or negative verbal feedback from an expert in the field of laparoscopic surgery. After this delivery of feedback, the students repeated the peg transfer task. Differences in performance pre- and post-feedback and also between the groups who received positive feedback (PF) vs negative feedback (NF) were analyzed. A survey was then completed by all the participants. Baseline task times were similar between groups (PF 209.3 seconds; NF 203 seconds, p = 0.58). The PF group averaged 1.83 first-time errors while the NF group 1 (p = 0.84). Post-feedback task times were significantly decreased for both groups (PF 159.75 seconds, p = 0.05; NF 132.08 seconds, p = 0.002). While the NF group demonstrated a greater improvement in mean time than the PF group, this was not statistically significant. Both groups also made fewer errors (PF 0.33 errors, p = 0.04; NF 0.38 errors, p = 0.23). When surveyed about their responses to standardized feedback scenarios, the students stated that both positive and negative verbal feedback could be potent stimulants for improved performance and motivation. Further research is required to better understand the effects of feedback on learner motivation and the interpersonal dynamic between mentors and their trainees.

Novel Use of Google Glass for Procedural Wireless Vital Sign Monitoring.

Purpose. This study investigates the feasibility and potential utility of head-mounted displays for real-time wireless vital sign monitoring during surgical procedures. Methods. In this randomized controlled pilot study, surgery residents (n = 14) performed simulated bedside procedures with traditional vital sign monitors and were randomized to addition of vital sign streaming to Google Glass. Time to recognition of preprogrammed vital sign deterioration and frequency of traditional monitor use was recorded. User feedback was collected by electronic survey. Results. The experimental group spent 90% less time looking away from the procedural field to view traditional monitors during bronchoscopy (P = .003), and recognized critical desaturation 8.8 seconds earlier; the experimental group spent 71% (P = .01) less time looking away from the procedural field during thoracostomy, and recognized hypotension 10.5 seconds earlier. Trends toward earlier recognition of deterioration did not reach statistical significance. The majority of participants agreed that Google Glass increases situational awareness (64%), is helpful in monitoring vitals (86%), is easy to use (93%), and has potential to improve patient safety (85%). Conclusion. In this early feasibility study, use of streaming to Google Glass significantly decreased time looking away from procedural fields and resulted in a nonsignificant trend toward earlier recognition of vital sign deterioration. Vital sign streaming with Google Glass or similar platforms is feasible and may enhance procedural situational awareness.

A Mixed-methods Analysis of a Novel Mistreatment Program for the Surgery Core Clerkship

Purpose To review mistreatment reports from before and after implementation of a mistreatment program, and student ratings of and qualitative responses to the program to evaluate the short-term impact on students. Method In January 2014, a video- and discussion-based mistreatment program was implemented for the surgery clerkship at the Stanford University School of Medicine. The program aims to help students establish expectations for the learning environment; create a shared and personal definition of mistreatment; and promote advocacy and empower ment to address mistreatment. Counts and types of mistreatment were compared from a year before (January–December 2013) and two years after (January 2014–December 2015) implementation. Students’ end-of-clerkship ratings and responses to open-ended questions were analyzed. Results From March 2014–December 2015, 141/164 (86%) students completed ratings, and all 47 (100%) students enrolled from January–August 2014 provided qualitative program evaluations. Most students rated the initial (108/141 [77%]) and final (120/141 [85%]) sessions as excellent or outstanding. In the qualitative analysis, students valued that the program helped establish expectations; allowed for sharing experiences; provided formal resources; and provided a supportive environment. Students felt the learning environment and culture were improved and reported increased interest in surgery. There were 14 mistreatment reports the year before the program, 9 in the program’s first year, and 4 in the second year. Conclusions The authors found a rotation-specific mistreatment program, focused on creating shared understanding about mistreatment, was well received among surgery clerkship students, and the number of mistreatment reports decreased each year following implementation.

Potential Nutritional Conflicts in Bariatric and Renal Transplant Patients

An increasing number of morbidly obese patients with end stage renal disease (ESRD) are sequentially undergoing bariatric surgery followed by renal transplantation. Discrepancies between the nutritional recommendations for obesity and chronic kidney disease (CKD) are often confusing for the obese patient in renal failure. However, when recommendations are structured according to stage and treatment of disease, a consistent plan can be clearly communicated to the patient. Therefore, to optimize patient and graft outcomes we present nutritional recommendations tailored to three patient populations: obese patients with ESRD, patients post Roux-en-Y gastric bypass (RYGBP) with ESRD, and patients post RYGBP and post renal transplantation.

Recurrent abdominal liposarcoma: analysis of 19 cases and prognostic factors.

AIM To evaluate the clinical outcome of re-operation for recurrent abdominal liposarcoma following multidisciplinary team cooperation. METHODS Nineteen consecutive patients who had recurrent abdominal liposarcoma underwent re-operation by the retroperitoneal sarcoma team at our institution from May 2009 to January 2012. Patient demographic and clinical data were reviewed retrospectively. Multidisciplinary team discussions were held prior to treatment, and re-operation was deemed the best treatment. The categories of the extent of resection were as follows: gross total resection (GTR), palliative resection and partial resection. Surgical techniques were divided into discrete lesion resection and combined contiguous multivisceral resection (CMR). Tumor size was determined as the largest diameter of the specimen. Patients were followed up at approximately 3-monthly intervals. For survival analysis, a univariate analysis was performed using the Kaplan-Meier method, and a multivariate analysis was performed using the Cox proportional hazards model. RESULTS Nineteen patients with recurrent abdominal liposarcoma (RAL) underwent 32 re-operations at our institute. A total of 51 operations were reviewed with a total follow-up time ranging from 4 to 120 (47.4 ± 34.2) mo. The GTR rate in the CMR group was higher than that in the non-CMR group (P = 0.034). CMR was positively correlated with intra-operative bleeding (correlation coefficient = 0.514, P = 0.010). Six cases with severe postoperative complications were recorded. Patients with tumor sizes greater than 20 cm carried a significant risk of profuse intra-operative bleeding (P = 0.009). The ratio of a highly malignant subtype (dedifferentiated or pleomorphic) in recurrent cases was higher compared to primary cases (P = 0.027). Both single-factor survival using the Kaplan-Meier model and multivariate analysis using the Cox proportional hazards model showed that overall survival was correlated with resection extent and pathological subtype (P < 0.001 and P = 0.02), however, relapse-free interval (RFI) was only correlated with resection extent (P = 0.002). CONCLUSION Close follow-up should be conducted in patients with RAL. Early re-operation for relapse is preferred and gross resection most likely prolongs the RFI.

PREDICT: Instituting an Educational Time Out in the Operating Room

Systematic time outs have been widely adopted in and outside the operating room (OR) to verify team preparedness, and review the details of planned procedures. These have been geared toward safety, which is paramount in every clinical encounter. In academic settings there is an added critical focus on education. As duty hour limits have reduced the time spent in the OR, and the complexity of surgical care has increased, maximizing the educational opportunities presented is imperative. A time out is an efficient platform for testing residents’ knowledge and facilitating faculty teaching. We developed the ‘‘Educational Time Out’’ (ETO), modeled after the World Health Organization’s (WHO) ‘‘surgical time out,’’ as a simple intervention before the start of a surgical case to review and assess trainees’ understanding of indications for surgery, the surgical plan, and technical considerations. This framework focuses learners’ attention and promotes the teaching experience at the outset of the case so that each moment forward has a high learning yield.

Assessment of Programs Aimed to Decrease or Prevent Mistreatment of Medical Trainees

Key Points Question What programmatic and curricular attempts have been reported to decrease the incidence of mistreatment of medical trainees? Findings After a systematic review of more than 3300 articles, only 10 peer-reviewed studies presented outcomes from an implemented program to prevent mistreatment. Overall, quality of included studies was low, and few studies reported any outcome data. Meaning There are very few published descriptions of programs attempting to decrease mistreatment of medical trainees, and there is a need for improved quantity and quality of such reports.
