Development of the education intervention
In the first place, the main problems regarding IT were identified. We developed a key driver diagram to analyze these problems and planned an education intervention which would approach each of them (Figure 1). In order to reduce interobserver bias, only two of the main investigators were responsible for performing the education intervention and participants’ evaluation. Both investigators received specific IT training by Pediatric Pneumologists.
A standardized educational checklist was created to evaluate IT, which was designed following Spanish guidelines recommendations (Spanish Pediatric Pneumology Association) and standardized checklists used in previous studies15.
The study was developed in three phases: baseline evaluation and education intervention (phase 1), and revaluation 1 month (phase 2) and 6 months after the education intervention (phase 3).
Phase 1 (P1): baseline evaluation and education intervention.
