Cost-Effectiveness of Ivabradine in the Treatment of Chronic Heart Failure. | LitMetric

Cost-Effectiveness of Ivabradine in the Treatment of Chronic Heart Failure.

AI Article Synopsis

Article Abstract

Background: In the Systolic Heart failure treatment with the I inhibitor Trial (SHIFT) randomised placebo-controlled trial, ivabradine was shown to reduce hospital admissions for worsening heart failure (HF) and deaths due to HF in patients with symptomatic systolic HF and an elevated resting heart rate (HR). This analysis evaluates the cost effectiveness of adding ivabradine to optimal standard HF treatment in patients with a HR≥77 bpm.

Methods: A Markov model was developed to assess the impact of ivabradine on mean survival and quality of life over a patient's lifetime (10 years). The hospitalisation and death rates were calculated using patient-level data from SHIFT. The reduction in quality of life due to HF hospitalisations was estimated directly from EQ-5D data collected in SHIFT. Australian costs were applied to the resource use from SHIFT.

Results: The modelled mean increase in survival with ivabradine was 0.115 years. The mean increase in quality-adjusted survival was 0.108 years. The average cost of ivabradine was A$2,957 and the cost savings associated with a reduction in HF hospitalisations was A$1,344. The cost per quality adjusted life year gained (QALYG) was A$14,905. The conservative approach to the modelled evaluation, as well as results of the sensitivity analysis, demonstrates that ivabradine is likely to be cost-effective in this indication.

Conclusions: The conservative approach to the modelled evaluation, as well as results of the sensitivity analysis, demonstrates that ivabradine is a cost-effective treatment in the Australian setting for HF patients with a HR≥77 bpm on optimal standard therapy with a cost per QALYG similar or lower than that for other publicly funded treatments.
