Uso de cámaras de inhalación en pediatría: eficacia de una intervención formativa en profesionales sanitarios

Objective. To assess the effectiveness of an educational intervention on the use of inhalation chambers among healthcare professionals working in pediatric settings. Methodology. A quasi-experimental pre-post study was conducted with physicians and nurses from pediatric emergency and inpatient units. Knowledge and skills were assessed using a checklist based on the SEPAR-ALAT consensus, applied to three practical scenarios according to pediatric age groups (<4 years, 4–8 years, and >8 years). The main outcome was the level of knowledge and technical skills. Sociodemographic and training-related variables were also collected. The McNemar test was used for pre-post comparison. Results. A total of 64 professionals participated. After the intervention, a significant improvement was observed in both knowledge and skills, with a notable reduction in the most frequent errors: failure to shake the inhaler between doses and failure to wait between inhalations. Discussion. Deficiencies were identified in the use of inhalation chambers according to pediatric age. The educational intervention was effective, although complementary strategies are needed to consolidate and maintain the competencies acquired.
