To benefit from inhalation therapy requires continuous and reliable inhalation with the correct technique. We investigated the effectiveness of a method in which a two-dimensional code (LogoQ®) with blue cells on a white background and the word “how to use” in yellow with a red border in the center were attached to the inhaler and instructions for use were provided to direct patients to the video site of the Environmental Restoration and Conservation Agency for repeated review of the technique. Of the 123 patients, 46 (mean age 58.1 years) completed the post-distribution evaluation after obtaining consent, the video viewing ratio was 52.0％, and the access ratio from the inhaler itself was approximately four times higher than that from the instructions. Those who accessed the video tended to have a lower DAI-10, an index of treatment comprehension, and a shorter duration of treatment. Although there was no effect of video viewing on the effectiveness of inhalation in a short period of time, free opinions were obtained that it contributed to the improvement and reconfirmation of the technique. The smartphone ownership ratio was 61.5％ in the video viewing group, and other patients accessed the videos from smartphones owned by their family members or others. Attaching the LogoQ® directly to the body of the inhaler led to the presentation of easy-to-understand instructions for accessing inhalation instructional videos. LogoQ® is expected to be used effectively as a tool for patients and their families to learn how to inhale.
