Adherence to Inhaled Corticosteroid Therapy and Its Clinical Impact on Asthma Control in Adults Living with Asthma in Northwestern Ethiopian Hospitals.

Background: Inhaled corticosteroids (ICS) are the backbone of and primary choice for long-term asthma control therapy; however, the level of adherence to this regimen has not yet been investigated, particularly in the study area of Northwest Ethiopia. Therefore, this study aimed to examine the level of adherence to ICS treatment and its impact on adults living with asthma in Northwestern Ethiopian hospitals. Materials and Methods: A multicenter institution-based survey was conducted in asthma patients treated with ICS-based regimens in public hospitals in Northwest Ethiopia. Adherence to ICS was measured with the Medication Adherence Report Scale for Asthma. Descriptive statistics were used to present respondents' characteristics, and logistic regression was used to test associations between predictors and outcome variables. A level of Results: Of a total of 422 approached subjects, 96.7% completed the survey. The mean (±SD) age of the participants was 49.82 (±16.1) years. The majority of participants (86.1%) had a low level of adherence to ICS treatment. A significant proportion (42%) of the respondents reported that they utilized ICS only before performing exercises that made them breathless. Around two-fifths of the participants used ICS either when they needed it or when they felt breathless. Furthermore, one-third of the study subjects reported that they either avoided or forgot to take ICS. Participants who had access to free healthcare services had better adherence to ICS ( Conclusion: This study found that adult patients with asthma had low levels of adherence to ICS therapy. Future prospective research in a larger population, focusing on identifying the obstacles to ICS adherence in patients living with asthma and creating successful intervention options, is recommended.
