Usefulness of a bidirectional e-learning material for explaining surgical anesthesia to cancer patients

Abstract

BackgroundWe developed an e-learning system, which is based on an interactive animation video that assists anesthesiologists in preanesthetic interviews. Materials and MethodsFirst, the feasibility of the system was investigated in 18 anesthesiologists and 95 volunteers from the general public. Content/quantity, operability, and satisfaction were assessed with a five-point scale. Secondly, a randomized controlled trial was conducted on 211 cancer patients who were scheduled to undergo general anesthesia. They were divided into an e-learning group (n=106) and a control group (n=105). The patients in the e-learning group watched the interactive animation before a preanesthetic interview by an anesthesiologist. ResultsIn 10 of the 11 items for content/quantity, operability, and satisfaction, the average score for both anesthesiologists and volunteers was ≥3.0 in feasibility study. Then, the level of patient comprehension of preoperative rounds and postoperative complications in the e-learning group was significantly higher than that in the control group (mean: 4.4±0.5 versus 4.1±0.7, P=0.003, and 4.3±0.5 versus 4.2±0.5, P=0.02); however, no significant difference in anxiety was seen between the two groups. Patient satisfaction in the e-learning group was significantly higher (mean: 4.3±0.5 versus 4.0±0.6, P=0.002). ConclusionThe e-learning system is an effective supplementary tool for preanesthetic interviews in cancer patients.
