Introduction: The additive EuroSCORE model correlates to in-hospital operative mortality in cardiac surgery [1]. The aim of this study was to determine if the EuroSCORE can predict duration of ventilation support, cardiac care unit stay and direct costs.

Method: We evaluated all patients who underwent open heart surgery at our institution between July 1, 2005 and November 24, 2005. EuroSCORE was collected prospectively for all cases. Direct variable costs (disposable materials and drugs) were calculated for each patient. The duration of postoperative ventilation support as well as the cardiac care unit length of stay (CCU-LOS) was registered. Values are given as mean ± standard deviation. Univariate linear regression analysis was used to test the correlation between the EuroSCORE and either costs, duration of ventilation support or CCU-LOS.

Results: Of the 133 patients enrolled 63.2% were males, mean age 55.9 ± 12.5 yr. According to EuroSCORE, 55 patients (41.4%) were at low, 41 (30.8%) at medium, and 37 (27.8%) at high risk. The relationship EuroSCORE vs. direct costs, duration of ventilator support and CCU-LOS respectively are shown in the table:

Costs were correlated with preoperative assessed risk with a correlation coefficient of 0.424 (P < 0.001). CCU-LOS and the duration of postoperative ventilator support were correlated with EuroSCORE with a correlation coefficient of 0.266 (P < 0.01) and 0.217 (P < 0.05), respectively.

Conclusions: In our patients, there is a strong correlation between the EuroSCORE and both direct costs and CCU-LOS. There is also a correlation between the score and the duration of ventilation support. Preoperative prediction of CCU-LOS and costs may be used in clinical practice for better resource utilization.
