Abstract

Cost-effectiveness analyses of interventions in the treatment for asthma have been performed in many countries around the world, including omalizumab. Systematic review and meta – analysis of the current state of the literature on the cost-effectiveness of omalizumab in the treatment for asthma has been conducted according to PRISMA guidelines based on database sources Pubmed, Cochrane and Embase with appropriate selection and exclusion criteria and assess quality of studies according to CHEERS. The systematic review and meta-analysis were performed through the ICER/QALY index converted to US Dollars (USD) 2020 based on the consumer price index (CPI). With 212 studies found based on search keywords, after screening according to selection and exclusion criteria, 06 studies were included in the meta - analysis. According to the CHEERS checklist, the quality of the studies ranging from 17 to 22 points with 60% good quality studies. This systematic review noted a relatively large variation in ICER/QALY between studies, ranging from $11,769/QALY to $897,559/QALY. In patients with uncontrolled severe persistent allergic asthma, particularly with corticosteroids, add-on therapy with omalizumab may be considered cost-effective when compared with standard therapy. The results of meta - analysis showed that ICER/QALY of add-on therapy with omalizumab compared with standard therapy resulted in $59.052/QALY (95% confidence interval: $34,457 - $83,648/QALY; p < 0.01). The add-on therapy with omalizumab may be considered cost-effective when compared with standard therapy in severe asthma.
