[Development of a One-minute Educational Video for Eye-drop Instillation and Changes in Instillation Behavior after Watching the Video].

ABSTRACT

We created a one-minute video titled "a simple method of eye-drop instillation" (video) for online instillation guidance, to compare the instillation method before and after study participants watch the video and verify the usefulness of watching the video. Moreover, we prepared a document questionnaire to investigate instillation habits and clarify instillation behavior. Study participants were randomly recruited from among students and faculty members via a poster posted at Tokushima Bunri University. The instillation behavior of the study participants was videotaped before and after they watched the video created by the authors. The images were played in a super slow motion, to confirm success or failure in instillation, drop sites, and eye-opening method. Of the 109 participants in the study, the successful instillation rate before and after watching the video was 55.0% and 69.7%, respectively. The use rate of wet wipes for finger disinfection before instillation increased from 0.0% before watching the video to 74.3% after watching the video. After watching the video, the blinking rate after instillation decreased from 95.4 to 45.0%, the rate of pressing the nasolacrimal duct increased from 2.8 to 77.1%, and the rate of wiping the drug solution spilled around the eyes increased from 89.9 to 98.2%. According to the questionnaire, 72.5% of the participants instilled one drop, 22.0% instilled two drops, and 5.5% instilled three drops or more. Watching the video significantly increased the successful instillation rate and improved instillation behavior. Thus, the video created by the authors can be used for online instillation guidance.
