Cost effectiveness of stent implantation versus PTCA: the BENESTENT experience

The aim of this paper is to assess the costs and effects of stent implantation versus percutaneous transluminal coronary angioplasty (PTCA). Data have been taken from both the BENESTENT-I and BENESTENT-II pilot study. Effects are expressed in terms of event-free survival and costs include those of the initial hospitalization and those during follow-up. The costs per additional event-free survivor after 7 months are estimated at Dfl 88,315, Dfl 28,127 and Dfl 6747 using respectively the results from the BENSTENT-I study, the BENESTENT-II pilot study and phase IV of the BENESTENT-II pilot study. Significant decreases in complications and ischaemic events have made stent implantation not only the most favourable in terms of event-free survival but also in terms of cost effectiveness.
