Immersive Video Modeling Versus Traditional Video Modeling for Teaching Central Venous Catheter Insertion to Medical Residents.

Background  Central Venous Catheter (CVC) placement is a common critical care procedure. Simulated practice has been shown to reduce its iatrogenic complications. Video modeling (VM) is an instructional adjunct that improves the quality and success of CVC insertion. Immersive VM can improve recall and skill translation, but its role in teaching medical procedures is not established. Research question/hypothesis We hypothesized that, relative to traditional VM, immersive VM would decrease cognitive load and enhance ultrasound-guided CVC insertion skill acquisition. Methods Thirty-two resident physicians from four specialties were randomized into traditional (control) or immersive VM (intervention) groups for three CVC training sessions. Cognitive load was quantified via NASA Task Load Index (TLX). Mean (± standard deviations) values were compared using two-tailed t-tests. Skill acquisition was quantified by procedural time and the average 5-point [EM1] [TB2] entrustment score of three expert raters. Results Overall entrustment scores improved from the first (3.44±0.98) to the third (4.06±1.23; p<0.002) session but were not significantly different between the control and intervention groups. There were no significant differences between NASA TLX scores or procedural time. Conclusion We found no significant difference in entrustment, cognitive load, or procedural time. Immersive VM was not found to be superior to traditional VM for teaching CVC insertion.

Communication, learning and assessment: Exploring the dimensions of the digital learning environment.

Advances in technology make it possible to supplement in-person teaching activities with digital learning, use electronic records in patient care, and communicate through social media. This relatively new "digital learning environment" has changed how medical trainees learn, participate in patient care, are assessed, and provide feedback. Communication has changed with the use of digital health records, the evolution of interdisciplinary and interprofessional communication, and the emergence of social media. Learning has evolved with the proliferation of online tools such as apps, blogs, podcasts, and wikis, and the formation of virtual communities. Assessment of learners has progressed due to the increasing amounts of data being collected and analyzed. Digital technologies have also enhanced learning in resource-poor environments by making resources and expertise more accessible. While digital technology offers benefits to learners, the teachers, and health care systems, there are concerns regarding the ownership, privacy, safety, and management of patient and learner data. We highlight selected themes in the domains of digital communication, digital learning resources, and digital assessment and close by providing practical recommendations for the integration of digital technology into education, with the aim of maximizing its benefits while reducing risks.
