Background: Preschool children with clinically-diagnosed asthma have a higher rate of emergency department visits and consume more resources for management than older children. However, no clinical trials have yet been performed measuring the impact of a combined diagnostic, therapeutic and educational pathway regimen for evaluation of wheezing control in children aged less than 6 years. The purpose of the present study was to assess the impact of a pediatric program developed in Italy, the Diagnostic Therapeutic Educational Pathway (DTEP), for asthma management in children less than 6 years old attending an asthma referral center. Methods: This is a retrospective population-based cohort study performed in children with asthma aged 0–5 years, attending at "Io e l'Asma center", Brescia, Italy between September 2007 and December 2014. The incidence rates (IRs) of hospitalization, emergency room visits, use of outpatient services and drug usage for dyspnea, wheezing, or respiratory symptoms were evaluated for time periods prior to and after DTEP intervention. Results: A total of 741 patients, aged 0–5 years completed the DTEP, including 391 and 350 children aged 0–2 and 3–5 years, respectively. The percentage of children aged 0–2 and 3–5 years showing improved control of wheezing symptoms during the 1st to 3rd visit interval as a result of the DTEP intervention increased from 39.5 to 60.9% and from 25.5 to 75.5%, respectively. During these periods, the IRs showed a significant decrease for all outcomes, from-8.6% to − 80.4%. Although specific IRs for drug prescriptions declined, particularly for LABA plus corticosteroids, antibiotics, and systemic corticosteroids, they increased for SABA, inhaled corticosteroid and leukotriene receptor antagonist usage. Conclusions: The results suggest that a real-world assessment of the integrated DTEP program for preschool children provides evidence for improved wheezing control and reduction of adverse therapeutic related outcomes.

Abstract: Background: In spite of some evidence for positive effects of patient's education to asthma self‐management by randomized clinical trials, there are few studies on the impact of patient’ s educational programs in the real world. We aimed to assess the impact of a diagnostic therapeutic educational pathway (DTEP) on asthma control of children and adolescents by comparing frequency of outcomes indicative of asthma control before and after attending the pathway. Methods: This is a retrospective cohort study including all patients aged 6‐11 and 12‐17 years who attended the DTEP in 2007‐2014. The DTEP includes 3 specialist's evaluations at 8‐ to 12‐week intervals and two follow‐up visits. Patients and their parents receive an educational course concerning prevention measures, early recognition of symptoms, and appropriate use of drugs and devices. The rates of hospitalizations, outpatient services, emergency room visits, and drug prescriptions were considered as outcomes and computed as number of events divided by person‐time. Results: A total of 806 patients were enrolled. A statistically significant decrease in rates from before to after DTEP was observed for almost all outcomes, in both age groups, with relative risks ranging from 0.12 to 0.60. The rates of drug prescription showed a statistically significant decrease, from before to after DTEP, for each type of medicine for asthma, in both age groups, from percent difference of −66% to −24.3%. Conclusions: The positive impact of this program on the outcomes indicative of asthma control in both children and adolescents suggests that it may be valuable for asthma management.
