Effect of preoperative two‐dimensional animation information on perioperative anxiety and knowledge retention in patients undergoing bowel surgery: a randomized pilot study

TLDR

Preoperative multimedia information can reduce patient anxiety and improve hospital experience, yet the impact of two‑dimensional animation for colorectal surgery patients has not been studied. This study investigated whether preoperative 2D animation reduces anxiety and improves knowledge retention in patients undergoing bowel surgery. Thirty‑one patients were randomized to a 13‑minute cartoon animation or no‑video group; anxiety was assessed at preadmission, post‑video, pre‑surgery, 24 h post‑surgery, and discharge using the Spielberger inventory and visual analogue scale, and both groups completed a knowledge retention questionnaire (the video group also completed a feedback questionnaire). The video group experienced an immediate anxiety reduction after viewing the animation (P = 0.03) and a significantly lower anxiety at discharge compared with the non‑video group (P = 0.03), but there was no difference in knowledge retention; 88 % of video viewers found the animation beneficial, indicating that 2D animation can reduce anxiety and improve the hospital experience.

Abstract

The use of multimedia information provided preoperatively can potentially reduce anxiety in patients and improve the hospital experience. However, the use of two-dimensional (2D) animation (cartoon) to provide information to patients undergoing colorectal surgery has not been investigated. This study investigated the effect of preoperative 2D information on anxiety and knowledge retention in patients undergoing bowel surgery.Patients were randomized to one of two groups; the video group watched a 13-min cartoon animation whereas the nonvideo group did not. Anxiety levels were measured at the preadmission clinic, postvideo, on the day of admission for surgery, within 24-h after surgery and before discharge using the Spielberger state-trait anxiety inventory and visual analogue scale. Both groups completed a knowledge retention questionnaire and the video group completed a feedback questionnaire about the animation.Thirty-one patients (16 video, 15 nonvideo) participated in the study. There was no significant difference in baseline anxiety score between two groups. An immediate reduction (P = 0.03) in anxiety score was observed in the video group after watching the video compared with baseline. There was a significant reduction in anxiety score in the video group at discharge compared with the nonvideo group (P = 0.03). There was no significant difference in knowledge retention between two groups. Eighty-eight per cent of patients who watched the video found it beneficial.2D animation is an effective medium for delivering information to patients undergoing bowel surgery and can potentially reduce anxiety related to surgery and improve the hospital experience.
