Comparing Effectiveness of Online Text-based and Video-based Material in Anesthesia with Jet Ventilation and Microlaryngeal Surgery: A Multicenter Randomized Trial

Objective: Effective clinical training is essential for healthcare personnel with clinical skill requirements. This study aimed to identify an effective learning medium for anesthesia residents by comparing text-based and video-based online training. Materials and Methods: This online, randomized, multicenter study was conducted between October 2020 and March 2021. Three Thai institutions were involved: the Faculty of Medicine Siriraj Hospital, Mahidol University; the Faculty of Medicine, Ramathibodi Hospital, Mahidol University; and the Faculty of Medicine, Songklanagarind Hospital, Prince of Songkla University. In all, 126 anesthesia residents were randomized into a “text group” and a “video group.” Four residents were excluded due to contamination of their learning material. The 122 eligible students undertook 3 knowledge and skill assessments (“Pretest, ” “24-hour posttest, ” and “3-month posttest”). The primary outcome was the gain score after training. This was measured in 2 ways: the difference between the 24-hour posttest and Pretest scores and the difference between the 3-month posttest and Pretest scores. Results: The mean gain scores for Pretest and 24-hour posttest were higher in the text group with no significant difference (P = 0.347). The mean differences between the 3-month posttest and Pretest scores were higher in the text group without a significant difference (P = 0.488). The mean satisfaction score was higher in the video group. Conclusion: Video-based e-learning training provided better satisfaction without significantly improving gain scores compared to text-based e-learning training. Online video-based was beneficial over text-based for ease of understanding in clinical learning points.
