Continued Validation of Ultrasound Guidance Targeting Tasks: Relationship with Procedure Performance.

RATIONALE AND OBJECTIVES: To determine if deliberative practice with novel ultrasound guidance targeting tasks improves simulated procedural skill. MATERIALS AND METHODS: In a nonrandomized interventional trial first year medical students practiced the previous described dowel and straw targeting tasks 1 hour a week for 4 weeks (training group) or had no training (controls). Afterward, they each performed a simulated amniocentesis (AMN) and chorionic villus sampling (CVS) procedure. Procedures were scored using a global rating scale (GRS) and compared between groups with Mann-Whitney U tests. Two-way random effects intraclass correlation coefficients for the inter- and intra-rater variability were calculated for each item in both GRS's. RESULTS: The training group (n = 22) had higher scores on several aspects and overall performance of AMN compared to controls (n = 15). There were no differences between groups for CVS. The inter-rater and intra-rater reliability of the GRS's for both AMN and CVS ranged from 0.16 to 0.89 with most values demonstrating good to excellent agreement. CONCLUSION: This study demonstrates validity evidence in the content and internal structure domains for the AMN and CVS simulators and their accompanying GRS's. Repetitive practice of the targeting tasks improved student performance in simulated AMN, but modifications are needed for it to be relevant to other procedures such as CVS.

Home Surgical Skill Training Resources for Obstetrics and Gynecology Trainees During a Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has created a unique educational circumstance in which medical students, residents, and fellows find themselves with a gap in their surgical training. We reviewed the literature, and nine categories of resources were identified that may benefit trainees in preventing skill decay: laparoscopic box trainers, virtual reality trainers, homemade simulation models, video games, online surgical simulations, webinars, surgical videos, smartphone applications, and hobbies including mental imagery. We report data regarding effectiveness, limitations, skills incorporated, cost, accessibility, and feasibility. Although the cost and accessibility of these resources vary, they all may be considered in the design of remote surgical training curricula during this unprecedented time of the COVID-19 pandemic.
