Objectives: Raltegravir, a novel integrase inhibitor, has shown great efficacy in reducing HIV viral load among treatment-experienced patients. A cohort state-transition model was used to assess the long-term effect of raltegravir treatment on costs and quality-adjusted life expectancy from a Swiss perspective. Methods: Patients were stratified into health states according to opportunistic infection status, HIV RNA level, and CD4 count, with each group assigned a treatment cost and utility (quality of life) score. Model inputs came from published studies, clinical trials, and database analyses. Results were used to calculate incremental cost-effectiveness ratio (ICER) of raltegravir use, expressed in Swiss francs (CHF) as incremental cost/qualityadjusted life-year (QALY) gained. Future costs and QALYs were discounted at 3% per year. Results: Five years of raltegravir treatment increased discounted qualityadjusted life expectancy by 3.73 years over placebo, with additional discounted cost of CHF 170,347, resulting in an ICER of CHF 45,687/QALY. ICERs ranged from CHF 42,751 to 53,478/QALY for treatment duration of 3 and 10 years, respectively. Results were most sensitive to changes in raltegravir treatment duration, source of estimated quality of life weights, and raltegravir price. Conclusions: Adding raltegravir to optimized background therapy was a cost-effective strategy for treatmentexperienced patients in Switzerland.
