Insights
International Asthma Guidelines significantly improved care for low-income children with asthma in São Paulo. The study showed reduced emergency visits and improved quality of life through education and proper medical treatment.
Area of Science:
- Pediatric Pulmonology
- Public Health
Background:
- Asthma management in low-income populations often relies on inadequate primary care, primarily using bronchodilators.
- International Asthma Guidelines offer a framework for effective asthma management.
Purpose of the Study:
- To evaluate the effectiveness of International Asthma Guidelines in low-income children with moderate to severe asthma in São Paulo, Brazil.
- To assess the impact of an educational program combined with guideline-based medical treatment.
Main Methods:
- A pre- and post-education study design with 50 asthmatic children over a 1-year follow-up.
- Patients served as their own controls, with parent interviews before and after the intervention.
Main Results:
- Implementation of International Asthma Guidelines, including inhaled steroids and an educational program, led to a significant decrease in asthma severity and impairment scores (p<.0001).
- Emergency room visits and hospital admissions were eliminated post-intervention.
- Children experienced improved quality of life and reduced asthma symptoms.
Conclusions:
- Combining medical care based on International Asthma Guidelines with patient education is effective in managing childhood asthma in underserved populations.
- This approach shifts asthma management from crisis-oriented to preventive chronic care, reducing healthcare costs and improving patient outcomes.
Abstract:
The present study was designed to evaluate the effectiveness of International Asthma Guidelines in low-income asthmatic children in the city of São Paulo, Brazil. Fifty children with moderate or severe asthma were evaluated. Patients were evaluated before and after a 1 yr follow-up period using a pre- and post-education design with patients acting as their own controls. Parents were interviewed before and 1 yr after the programme. Most of the children were receiving inadequate medical care from their primary physicians, based mainly on bronchodilators. After the educational programme combined with a medical treatment based mainly on inhaled steroids, there was a decrease in emergency room visits and no need for hospital admissions. There was also a significant decrease in asthma severity and impairment scores (p<.0001). The combination of good medical care and an educational programme can reduce the symptoms of asthma and significantly increase the quality of life, as well as decreasing the costs of asthma treatment. We conclude that by applying the International Asthma Guidelines substantial success was achieved, resulting in moving the patients from crises-orientated management into a chronic care and preventive management mode.
