Cost of transcatheter aortic valve implantation and factors associated with higher hospital stay cost in patients of the FRANCE (FRench Aortic National CoreValve and Edwards) registry.

BACKGROUND

Currently, several anatomical approaches and intervention sites can be used to perform transcatheter aortic valve implantations (TAVIs), often with no clinical indications for choosing one or another. While these choices can have an impact on resource consumption, no costing study is available in the European context to provide information on resource use and assist decision-making.

AIMS: To provide comparative data on the cost of the TAVI procedure, depending on anatomical approach and intervention site used, from a hospital perspective, and to analyze factors associated with cost of hospital stay.

METHODS

Multicentre national registry data were collected in 16 centres between January and October 2009. For 287 patients, a descriptive costing study and a multivariable analysis of hospital stay cost were performed.

RESULTS

The mean cost of the TAVI procedure was €22,876 and the mean initial hospital stay cost was €35,164. The procedure cost, excluding valve cost, did not differ between anatomical approaches and was highest in the hybrid room and lowest in the catheterization laboratory. Factors associated with higher hospital stay cost were transapical approach, Society of Thoracic Surgeons score>10%, warfarin use at inclusion, complications during procedure and pacemaker implantation following valve implantation.

CONCLUSIONS

If clinical considerations do not interfere, hospital staff may find it economically favorable to opt for the catheterization laboratory and against the hybrid room. The mean hospital stay cost is higher than the tariff paid in 2011, a difference that has grown since the change in tariff in 2012, representing an economic disincentive for the uptake of TAVI in France.
