Bronchiolitis: A Real-Life Report of Increasing Compliance to Treatment Guidelines

Le résumé fourni par la source

BACKGROUND: Bronchiolitis accounts for a substantial number of pediatric hospitalizations and its epidemiology closely parallels that of respiratory syncytial virus (RSV), its principal etiological agent. International guidelines recommend supportive therapy based primarily on oxygen supplementation and hydration. METHODS: This study aimed to assess, across three pediatric wards, the impact of internal monitoring and targeted educational interventions on adherence to bronchiolitis management guidelines. Focus was placed on evaluating the effectiveness of tailored strategies in enhancing the appropriateness of treatment practices. Each center independently developed an audit and feedback strategy aligned with local practices and available resources. In Center 1, monthly staff meetings included guideline refreshers throughout the epidemic season. Center 2 appointed two attending physicians to monitor treatment prescriptions and report deviations. Center 3 established an internal protocol through staff consensus, followed by monthly review sessions. In this retrospective analysis, all consecutive patients admitted with bronchiolitis during the winter seasons of 2022-2023 and 2023-2024 (Period 2) were compared with those admitted in 2021-2022 (Period 1). RESULTS: A total of 623 infants under 24 months of age were included, 451 (72%) of whom tested positive for RSV. Their median length of hospital stay was 6 days; 26 infants (4%) required intensive care, and no deaths were recorded. A comparative analysis of the treatment modalities used-high-flow nasal cannula (HFNC) oxygen therapy, inhaled medications, corticosteroids, and antibiotics-revealed a reduced use of non-recommended therapies (e.g., nebulized β2-agonists, steroids, and antibiotics) in Period 2, alongside heterogeneous patterns in HFNC use. Center-specific strategies, tailored to team dynamics and resource availability, effectively promoted greater adherence to evidence-based guidelines. CONCLUSIONS: Our findings suggest that structured internal interventions can lead to more appropriate bronchiolitis management and the improved standardization of care.
