Insights
Asthma medication adherence in children is crucial. In Dutch primary care, inhaled corticosteroid adherence was low, suggesting it
Area of Science:
- Pediatric Pulmonology
- Real-world Evidence in Asthma Management
- Medication Adherence Research
Background:
- Effective asthma management in children hinges on consistent treatment adherence.
- Understanding real-world medication use and adherence patterns is key to improving pediatric asthma care.
Purpose of the Study:
- To investigate prescription trends for asthma medications in children.
- To assess adherence rates to asthma drugs in pediatric populations.
- To identify factors associated with medication adherence in children with asthma.
Main Methods:
- A population-based cohort study utilized Dutch primary care database records (IPCI) from 2000-2012.
- Included 176,516 children aged 5-18 years, analyzing asthma medication prescriptions.
- Adherence was measured using Medication Possession Ratio (MPR) and Controller to Total drug ratio (CTT).
Main Results:
- The asthma cohort (n=14,303) primarily received short-acting beta-agonists (SABA) and inhaled corticosteroids (ICS).
- Median MPR for ICS was 56%, indicating relatively low adherence.
- Children with high ICS adherence (MPR > 87%) were younger, had more specialist visits, and experienced more exacerbations.
Conclusions:
- Dutch primary care predominantly prescribed SABA and ICS for pediatric asthma.
- Adherence to inhaled corticosteroids (ICS) among children with asthma was found to be low.
- Good adherence correlated with indicators of more severe asthma, suggesting adherence is linked to treatment necessity and medical follow-up intensity.
Unlabelled:
Adherence to treatment remains important for successful asthma management. Knowledge about asthma medication use and adherence in real-life offers opportunities to improve asthma treatment in children.
Objective:
To describe prescription patterns, adherence and factors of adherence to drugs in children with asthma.
Methods:
Population-based cohort study in a Dutch primary care database (IPCI), containing medical records of 176,516 children, aged 5-18 years, between 2000 and 2012. From asthma medication prescriptions, age, gender, seasonal and calendar year rates were calculated. Adherence was calculated using medication possession ratio (MPR) and ratio of controller to total asthma drug (CTT). Characteristics of children with high-vs.-low adherence were compared.
Results:
The total asthma cohort (n = 14,303; 35,181 person-years (PY) of follow-up) was mainly treated with short-acting β2-agonists (SABA; 40 users/100 PY) and inhaled corticosteroids (ICS; 32/100 PY). Median MPR for ICS was 56%. Children with good adherence (Q4 = MPR > 87%) were younger at start of ICS, more often visited specialists and had more exacerbations during follow-up compared to children with low adherence (Q1 = MPR < 37%).
Conclusion:
In Dutch primary care children with asthma were mainly prescribed SABA, and ICS. Adherence to ICS was relatively low. Characteristics of children with good adherence were compatible with more severe asthma, suggesting that adherence is driven by treatment need or intensity of medical follow-up.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
