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.
