Article Synopsis
  • The study aims to explore how different factors affect the autonomy of general surgery residents during robotic surgeries, specifically focusing on aspects like resident seniority, surgeon experience, and case volume.
  • Data was collected from robotic surgeries conducted between July 2019 and June 2021 involving general surgery residents, analyzing individual console time (ICT) for different procedures and comparing results across varying resident levels.
  • Findings revealed that senior residents had significantly more ICT than juniors, and the experience level of the surgeon influenced resident autonomy, while the number of robotic surgeries performed by the surgeon did not correlate with ICT.

Article Synopsis
  • The study aimed to evaluate how operative coaching (OC) impacts surgery residents' skills and perceived autonomy during their chief year, as well as collect feedback from participants about their experiences in the program.
  • Over 441 evaluations from multiple surgical cases indicated significant improvements in residents' general skills, step-specific guidance needs, and perceived entrustment by attendings throughout the year.
  • Both residents and attendings valued the OC elements like real-time feedback and direct observation, which enhanced learning and teaching, though there was a discrepancy between chiefs' self-assessment and attendings' perceptions of their autonomy.

Background: Rater-based assessment and objective assessment play an important role in evaluating residents' clinical competencies. We hypothesize that a cumulative sum (CUSUM) chart of operative time is a complement to the assessment of chief general surgery residents' competencies with ACGME Milestones, aiding residency programs' determination of graduating residents' practice readiness.

Study Design: We extracted ACGME Milestone evaluations of performance of operations and procedures (POP) and 3 objective metrics (operative time, case type, and case complexity) from 3 procedures (cholecystectomy, colectomy, and inguinal hernia) performed by 3 cohorts of residents (N = 15) during their PGY4-5.

Objective: Robotic-assisted surgery is an increasing part of general surgery training, but resident autonomy on the robotic platform can be hard to quantify. Robotic console time (RCT), the percentage of time the resident controls the console, may be an appropriate measure of resident operative autonomy. This study aims to characterize the correlation between objective resident RCT and subjectively scored operative autonomy.

Purpose: Resident involvement would likely lead to prolonged operative time of a surgical case performed at academic medical centers. However, little is known about factors beneath this phenomenon. The purpose of this study was to investigate whether factors from case (procedure type, surgical case complexity, and surgical approach), teacher (attending surgeon experience and gender), and learner (resident postgraduate training year and gender) would influence operative time of surgical cases involved teaching a resident (SCT).

Operative coaching offers a unique opportunity to strengthen surgery residents' skill sets and practice readiness. However, institutional organizational capacity may influence the ability to successfully implement and sustain a coaching program. This review concentrates on the implementation requirements as they relate to institutional organizational capacity to help evaluate and determine if adopting such a coaching model is feasible.

Article Synopsis
  • The study aimed to identify factors that predict whether surgical residents will be entrusted with greater autonomy in the operating room, intending to improve teaching methods by attending surgeons.
  • The researchers analyzed 273 performance evaluations from 91 surgical cases and found that step-specific guidance was the strongest predictor of a resident's future entrustment.
  • The results suggest that by focusing on specific steps in procedures, attending surgeons can better evaluate and enhance residents' readiness for independent practice, leading to improved surgical teaching strategies.

Objectives: To investigate the effects of a stress management workshop on medical students' knowledge of stress and potential coping strategies.

Methods: A panel discussion with small group breakouts on stress in clinical medicine, learning challenges, competition with colleagues, handling stressful events, and recognizing burnout symptoms was conducted with medical students entering clerkships. A longitudinal survey design was utilized to measure pre-, post-, and long-term (3-month) changes in knowledge (impact of stress on personal health, learning, and patient care), confidence, perceived skills, and attitude (towards utilizing adaptive coping strategies) among participating students ( = 135).

Introduction: The goal of this study was to explore the resident construct for their perceived successful method of actions that lead to OR autonomy during residency and the strategies they employed.

Methods: We conducted focus group interviews with residents from the General Surgery (GS) and Obstetrics & Gynecology (OBGYN) departments at a single academic institution across all clinical postgraduate years (PGY) using convenience sampling. Audio recordings of each interview were transcribed, analyzed and emergent themes were identified using a framework method.

Objective: This study aimed to identify the empirical processes and evidence that expert surgical teachers use to determine whether to take over certain steps or entrust the resident with autonomy to proceed during an operation.

Background: Assessing real-time entrustability is inherent in attending surgeons' determinations of residents' intraoperative autonomy in the operating room. To promote residents' autonomy, it is necessary to understand how attending surgeons evaluate residents' performance and support opportunities for independent practice based on the assessment of their entrustability.

Background: Traditionally, surgical training has used an apprenticeship model but has more recently moved to a service-based model, with groups of residents working with groups of attending surgeons. We developed an apprenticeship rotation to enhance one-on-one interaction between chief residents and selected faculty. We hypothesized that the apprenticeship rotation would be effective for teaching nontechnical skills (NTS) and core competencies.
