RESUMO
Background: Bronchiolitis is a leading cause of pediatric hospitalizations. A high-flow nasal cannula (HFNC) does not significantly improve clinical outcomes and is associated with increased costs and intensive care unit (ICU) utilization. Despite this, hospitals continue to overuse HFNC in children with bronchiolitis. We aimed to reduce HFNC initiation in children hospitalized with bronchiolitis by 20 percentage points within 6 months. Methods: This study included patients aged 1 month to 2 years diagnosed with bronchiolitis, excluding patients with prematurity less than 32 weeks or preexisting cardiopulmonary, genetic, congenital, or neuromuscular abnormalities. Measures included HFNC utilization, length of stay, length of oxygen supplementation (LOOS), ICU transfers, and emergency department (ED) revisits and readmissions. For our primary intervention, we implemented a HFNC initiation protocol incorporating a respiratory scoring system, a multidisciplinary care-team huddle, and an emphasis on supportive care. Staff education, electronic health record integration, and audit and feedback were used to support implementation. Statistical process control charts were used to track metrics. Results: We analyzed 325 hospitalizations (126 baseline and 199 postintervention). The proportion of children hospitalized with bronchiolitis who received HFNC decreased from a mean of 82% to 60% within 1 month of implementation. Length of stay decreased from a median of 54 to 42 hours, and length of oxygen supplementation decreased from 50 to 38 hours. There were no significant changes in ICU transfers, 7-day ED revisits, or readmissions. Conclusions: Implementing a HFNC initiation protocol can safely reduce the overutilization of HFNC in children hospitalized with bronchiolitis.
RESUMO
BACKGROUND: Antiretroviral (ARV) management in pediatrics is a challenging process in which multiple barriers to optimal therapy can lead to poor clinical outcomes. In a pediatric HIV clinic, we implemented a systematic ARV stewardship program to evaluate ARV regimens and make recommendations for optimization when indicated. METHODS: A comprehensive assessment tool was used to screen for issues related to genotypic resistance, virologic/immunologic response, drug-drug interactions, side effects and potential for regimen simplification. The ARV stewardship team (AST) made recommendations to the HIV clinic provider, and followed patients prospectively to assess clinical outcomes at 6 and 12 months. RESULTS: The most common interventions made by the AST included regimen optimization in patients on suboptimal regimens based on resistance mutations (35.4%), switching to safer ARVs (33.3%) and averting significant drug-drug interactions (10.4%). In patients anticipated to have a change in viral load (VL) as a result of the AST recommendations, we identified a significant benefit in virologic outcomes at 6 and 12 months when recommendations were implemented within 6 months of ARV review. Patients who had recommendations implemented within 6 months had a 7-fold higher probability of achieving a 0.7 log10 reduction in VL by 6 months, and this benefit remained significant after controlling for adherence [adjusted odds ratio: 6.8 (95% confidence interval: 1.03-44.9; P <0.05)]. CONCLUSIONS: A systematic ARV stewardship program implemented at a pediatric HIV clinic significantly improved clinical outcomes. ARV stewardship programs can be considered a core strategy for continuous quality improvement in the management of HIV-infected children and adolescents.
