Patient-Provider Communication
Surprising Statistics: Adherence to Asthma Therapies
- An estimated 50% of medications prescribed for asthma are taken by patients1
- 82% of patients with asthma fail to refill prescriptions for inhaled corticosteroids2
- 11% of patients in clinical trials used less than 80% of their medications3
- Poor adherence is linked with outcomes such as mortality, asthma symptoms, direct and indirect costs and quality of life4
- Asthma treatment adherence tends to be poor with rates of < 50% in children and 30-70% in adults depending on patient specific factors such as4
- Age
- Sex
- Ethnicity
- Country
- Data suggests higher level of adherence is associated with reduced risk of severe asthma exacerbation4
- Trustworthy, strong patient provider relationship is needed for improvement of adherence rates through which providers must recognize and incorporate patient preferences5
