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.

Asthma-I: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Inhaled Medications

Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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.
