Impella Versus VA-ECMO for Patients with Cardiogenic Shock: Preliminary Cost-Effectiveness Analysis in the Italian...

Cardiogenic shock (CS) is a life-threatening failure of the heart to supply adequate blood, requiring immediate treatment. Although nowadays Impella^® heart pumps and veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) are both widely employed in routine clinical practice for the management of patients with CS, extensive comparative information on their cost-effectiveness is lacking. The aim of the present study was to conduct a cost-effectiveness analysis comparing Impella to VA-ECMO in patients with CS from the National Healthcare Service (NHS) perspective in Italy. A secondary objective was to compare costs from both NHS and hospital perspectives.

A Markov model projected, on a lifetime horizon, life years (LYs), quality-adjusted life years (QALYs), and costs associated with Impella and VA-ECMO. Costs from the NHS perspective were estimated mainly through Italian reimbursement rates, while hospital costs were derived from a clinical center in Italy.

From an NHS perspective, Impella showed lower costs and better life expectancy and patients' quality of life (€50,303, 1.544 LYs, 0.905 QALYs) compared to VA-ECMO (€76,795, 1.391 LYs, 0.784 QALYs). DRG overall reimbursements for Impella (€49,998) do not completely cover the hospital costs and the cost for the technology (€57,770). Conversely, the hospital cost for the strategy VA-ECMO (€52,190) is lower than the NHS overall reimbursements (€76,790).

Our analysis suggests that Impella may be cost-saving over VA-ECMO, while also providing better health outcomes for patients with CS; however, discrepancies in costs and reimbursement rates were observed, likely due to variability in patient care and hospital resource utilization. Future real-world studies are needed to confirm these findings, but decision-makers can use this data as an initial reference for health technology assessments in Italy.
