Effect of a Daily Text Reminder on Asthma Medication Use, Symptom Control, and Lung Function in Children

Effect of the Visual Reminder "AdhasText" on Adherence to Inhaled Corticosteroids, Symptom Control, and Pulmonary Function in Children With Asthma: A Randomized Clinical Trial

The goal of this clinical trial is to learn if a daily text reminder ("AdhasText") can help children with asthma use their inhalers regularly, control their symptoms, and improve their lung function. The main questions it aims to answer are:

Does the daily text reminder improve adherence to inhaled corticosteroids in children with asthma? Does the text reminder help children with asthma control their symptoms better? Does the text reminder improve lung function in children with asthma?

Researchers will compare children who receive the daily text reminder with usual care to children who receive usual care (without the reminder) to see if the text reminder improves adherence, symptom control, and lung function.

Participants will:

Receive a daily text reminder or usual care (no reminder) for 90 days Complete questionnaires about their asthma symptoms at 45 and 90 days Have spirometry tests to measure lung function at the start of the study and 90 days

Inclusion Criteria:

• Children aged 5 to 14 years with a clinical diagnosis of asthma
• Children who required initiation of treatment with a fixed and regular dose of inhaled corticosteroids
• Mothers or caregivers who had a mobile phone capable of sending and receiving text messages

Exclusion Criteria:

• Children with congenital heart disease
• Children who were unable to perform baseline spirometry
• Children who experienced at least one exacerbation during the pre-randomization period
