Comparison between traditional and goal directed perfusion in cardiopulmonary by-pass. Adaptation of a differential cost analysis

Massimiliano Povero, Lorenzo Pradelli



BACKGROUND: A previous patient-level discrete event simulation (DES) model was developed to perform an economic evaluation of GDP strategy with respect to TP in US. Aim of this supplement is provide results of the adaptations of the differential cost analysis to Belgium, Canada, France, Germany, Italy, and UK. METHODS: A Discrete Event Simulation model was developed to compare TP and GDP strategy in patients undergoing CPB. National perspective was adopted to calculate costs associated to each event while GDP strategy was exploited the introduction of Sorin Heartlink (HL) Card/GDP Card and Sorin Connect (electronic data management system). RESULTS: GDP reduces the total cost with respect to traditional perfusion; furthermore the cost of GDP strategy (Sorin GDPTM Monitor and Sorin ConnectTM) is completely offset by the saving in hospital stay. CONCLUSION: GDP seems to improve significantly the main outcomes related to CPB surgery, when compared to TP techniques. Additional costs due to perform GDP strategy have no impact on the total cost since completely offset by the savings in hospital cost.
