Validation of Use of Flipped Classroom for Surgery Core Clerkships.

BACKGROUND: The flipped classroom (FC) is an integrated learning paradigm that equips students with self-directed study materials before scheduled meeting times allowing for the deeper application of acquired knowledge with an instructor. There is limited data on the application of FC to clinical undergraduate medical education and particularly as it applies to a surgical clerkship. METHODS: This study is a four-year retrospective study that includes two cohorts of students who matriculated through two training paradigms, traditional classroom (TC) and FC. Information regarding the FC cohort was collected from June 2018 to July 2020 (N=166). A two-year matched historical cohort of students enrolled in the clerkship and taught with the TC paradigm from June 2016 to July 2018 was used for comparison (N=157). The primary aim of this study is to assess the National Board of Medical Examiners (NBME) surgery shelf performance when the FC model is utilized compared to the TC model. This study will validate a prior similar study that had a smaller cohort with different secondary endpoints. Therefore, the secondary aim of this study assesses how teaching style can affect other performance metrics of a rotation (such as clinical performance, quizzes, Objective Structured Clinical Examinations (OSCE), and practicums) and how time was utilized by faculty, staff, and students. RESULTS: There was no difference in overall NBME surgery shelf performance when comparing the FC to the traditional classroom teaching (68.94 vs 70.34, P= 0.1667). Likewise, there was no difference in quiz performance. The FC did allow instructors to spend more time in other clinical components of the curriculum leading to a significant difference in student practicum (84.2 vs 88.26, P = 0.0186) and OSCE grades (87.54 vs 90.58, P <0.0001). CONCLUSION: The surgery NBME shelf performance is not compromised by FC and therefore can be used as an alternative to traditional classroom setting for teaching medical knowledge to surgery clerkship students. In addition, the FC can improve time management for instructors allowing for improved teaching and development in other components of the surgery curriculum.

Adenoma Detection Rate in Colonoscopy: Does the Participation of a Resident Matter?

Presently, endoscopic procedures are a requirement for training competency for completion of a general surgery residency. There are no studies to date that have assessed whether having a resident perform a colonoscopy impacts quality indicators such as adenoma detection rate (ADR). To retrospectively review ADR in adult patients, who undergo screening colonoscopy at a single institution with (ColFacR) and without (ColFac) the participation of a general surgery resident. A total of 792 patients were identified in the database screening colonoscopies between the ages of 45 and 80 from July 2013 to June 2015. Of those, 501 were reviewed after exclusion criteria. When comparing the ColFac group (n = 316) to the ColFacR group (n = 185), there were no differences between age, gender, body mass index, American Society of Anesthesiologists score, or quality of bowel preparation. The mean number of total polyps, hyperplastic polyps, and adenomatous polyps retrieved were similar between the two groups. There was no difference in the ADR for the ColFac cases and ColFacR cases (25.95% vs 27.03%, respectively, P = 0.834). ADR is similar in elective colonoscopies that were performed with or without a general surgery resident. The participation of a general surgery resident in routine colonoscopies should not impact reported quality indicators.

Laparoscopic colectomy for Crohn's colitis. A large prospective comparative study.

INTRODUCTION: The purpose of this study was to compare short-term outcomes of laparoscopic (LC) vs open colectomy (OC) in patients with Crohn's colitis. MATERIALS AND METHODS: We collected data on all patients undergoing colectomy for primary or recurrent Crohn's disease confined to the colon from July 2002 to August 2008. Patient and disease-specific characteristics and perioperative and short-term postoperative outcomes were prospectively collected and analyzed. RESULTS: A total of 125 patients underwent colectomy during the study period, 55 (44%) LC. There were six conversions (10.9%). Median operative time was shorter in the LC group (212 min, interquartile range (IQR) 180-315 LC vs 286 min, IQR 231-387 OC, p = 0.032). Estimated blood loss was less for the LC group (100 ml, IQR 90-250 LC vs 250 ml, IQR 100-400 OC, p = 0.002). Earlier return of bowel function was noted in the LC group (3 days vs 4 days, OC). Length of post-op stay was shorter in the LC group (6 days, IQR 5-8 vs 8 days, IQR 6-10 OC, p = 0.001). There was one death in the OC group. Postoperative complications occurred in eight (14.5%) LC patients vs 16 (22.9%) OC. Disease recurrence rate was 16%, 10.9% LC and 20% OC, respectively. CONCLUSIONS: Laparoscopic colectomy is a safe and effective technique in the hands of experienced surgeons. Benefits of laparoscopic colectomy in Crohn's disease include reduced operative blood loss, quicker return of bowel function, and shorter hospital length of stay.

Cardiovascular health disparities: a systematic review of health care interventions.

Racial and ethnic disparities in cardiovascular health care are well documented. Promising approaches to disparity reduction are increasingly described in literature published since 1995, but reports are fragmented by risk, condition, population, and setting. The authors conducted a systematic review of clinically oriented studies in communities of color that addressed hypertension, hyperlipidemia, physical inactivity, tobacco, and two major cardiovascular conditions, coronary artery disease and heart failure. Virtually no literature specifically addressed disparity reduction. The greatest focus has been African American populations, with relatively little work in Hispanic, Asian, and Native American populations. The authors found 62 interventions, 27 addressing hypertension, 9 lipids, 18 tobacco use, 8 physical inactivity, and 7 heart failure. Only 1 study specifically addressed postmyocardial infarction care. Data supporting the value of registries, multidisciplinary teams, and community outreach were found across several conditions. Interventions addressing care transitions, using telephonic outreach, and promoting medication access and adherence merit further exploration.
