Cost-benefits of incorporating levosimendan into cardiac surgery practice: German base case.

OBJECTIVE: To evaluate the cost-benefit of using levosimendan compared with dobutamine, in the perioperative treatment of patients undergoing cardiac surgery who require inotropic support. METHODS: A two-part Markov model was designed to simulate health-state transitions of patients undergoing cardiac surgery, and estimate the short- and long-term health benefits of treatment. Hospital length of stay (LOS), mortality, medication, and adverse events were key clinical- and cost-inputs. Cost-benefits were evaluated in terms of costs and bed stays within the German healthcare system. Drug prices were calculated from the German Drug Directory (€/2014) and published literature, with a 3% annual discount rate applied. The base case analysis was for a 1-year time horizon. RESULTS: The use of levosimendan vs dobutamine was associated with cost savings of €4787 per patient from the German hospital perspective due to reduced adverse events and shorter hospital LOS, leading to increased bed capacity and hospital revenue. LIMITATIONS: A pharmacoeconomic calculation for the specific situation of the German healthcare system that is based on international clinical trial carries a substantial risk of disregarding potentially relevant but unknown confounding factors (i.e., ICU-staffing, co-medications, standard-ICU care vs fast-tracking, etc.) that may either attenuate or increase the outcome pharmacoeconomic effects of a drug; however, since these conditions would also apply for patients treated with comparators, their net effects may not necessarily influence the conclusions. CONCLUSIONS: The use of levosimendan in patients undergoing cardiac surgery who require inotropic support appears to be cost-saving. The results of the analysis provide a strong rationale to run local clinical studies with pharmacoeconomic end-points which would allow a much more precise computation of the benefits of levosimendan.

Economic evaluation of levosimendan versus dobutamine for the treatment of acute heart failure in Italy.

INTRODUCTION: Inodilators are the first-choice class of drugs for the treatment of acute heart failure (AHF). Levosimendan is a relatively recent inodilatory agent, presenting superior outcomes in comparison with traditional inotropes. METHODS: An economic evaluation of levosimendan for the treatment of AHF in Italy was performed. In a retrospective study conducted on patients with AHF admitted to a teaching hospital in Rome, two groups were derived from an observational registry: 147 patients treated with levosimendan and 145 treated with dobutamine. Follow-up was at 1 year after treatment. In the reference study looked at in this paper, treatment with levosimendan reduced mean length of stay (LOS) by 1.5 days (P<0.05). Reduction in the rehospitalization rate was 6.7% (P<0.05). Mortality rate at 1 month was reduced by 4.8% (P<0.05). RESULTS: Based on the reference study, a cost analysis from the hospital perspective was carried out. The incremental cost of treatment with levosimendan (€697) was equivalent to the incremental savings (€694), the latter being obtained from the reduction in LOS (€508) and rehospitalization rate (€186). CONCLUSION: Despite the limitations of this study, and even neglecting all nonmonetary health gains as additional outcomes, levosimendan appears to be a competitive alternative compared with dobutamine for the treatment of AHF in the Italian hospital setting.
