Insights

Improper inhaler technique is common in Vietnamese children with asthma, leading to poor asthma control. Caregiver involvement in medication adherence and monitoring is crucial for improving technique and control.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Medicine
  • Public Health

Background:

  • Limited data exists on inhaler technique and asthma control in Vietnam.
  • Improper inhaler technique is a known factor negatively impacting asthma management.
  • This study addresses the prevalence and impact of incorrect inhaler use in pediatric asthma patients in Vietnam.

Purpose of the Study:

  • To determine the prevalence of improper inhaler technique in children with asthma in Vietnam.
  • To assess the association between improper inhaler technique and uncontrolled asthma.
  • To examine the role of caregivers in pediatric asthma management concerning inhaler technique.

Main Methods:

  • An analytical cross-sectional study design was employed.
  • Data were collected from 186 children with asthma and their caregivers.
  • Logistic regression analysis was used to identify associations between variables.

Main Results:

  • 45.2% of children exhibited improper inhaler technique.
  • Improper inhaler technique was significantly associated with uncontrolled asthma (AOR = 2.33).
  • Caregiver factors, including medication adherence and MDI monitoring, were linked to improper technique.

Conclusions:

  • Improper inhaler technique is prevalent and linked to poor asthma control in Vietnamese children.
  • Caregiver engagement in medication adherence and monitoring is vital.
  • Interventions targeting caregiver practices may improve pediatric asthma outcomes.

Inhaled Medications01:23

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 Management01:20

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.
