Abstract
Asthma is a chronic, heterogeneous and inflammatory disease of the airways that requires specific care and adequate treatment to remain under control. The objective of this study was to carry out a feasibility study with patients diagnosed with asthma from a public pharmacy in the state of Rio Grande do Sul, randomized into four groups: intervention by telephone, intervention by video, intervention by text message (SMS) and control group. The primary outcome was change in asthma control as assessed by the Asthma Control Test (ACT) at time zero and after three months. As a result, there was a significant increase in the mean ACT score, going from 15.57 to 17.80 points (p=0.026) only in the video intervention group. Other groups did not show statistically significant changes. Finally, the use of technologies with audiovisual resources has been shown to be effective in improving the use of the inhaler device, resulting in better asthma control.
