The EuroSCORE model significantly predicted direct operative costs in patients undergoing open heart surgery, with costs increasing by 3.5% (95% CI 2.3-4.7; P<0.0001) for each 1-point rise in score.

Does the EuroSCORE model predict direct costs in patients undergoing open heart surgery?
The EuroSCORE model, originally developed to predict 30-day postoperative mortality, can also effectively predict direct operative costs and resource consumption in patients undergoing cardiac surgery.
Effect estimate: 3.5% increase per score point (95% CI 2.3-4.7)
p-value: p=<0.0001
OBJECTIVE: The aim of this study is to determine if a preoperative risk stratification model can identify different surgical costs. METHODS: Four hundred and eighty-eight patients undergoing open heart surgery between March 2000 and March 2001 were classified with the EuroSCORE model. Direct variable costs were prospectively collected, surgical team costs excluded. The multivariate analysis was used to find variables independently associated with costs. RESULTS: Of the 488 patients enrolled 342 (70%) were males, mean age 65+/-10 years, 57 (12%) had myocardial infarction, 20 (4%) had ejection fraction 6863+/-861 Euro; 3-4 ==> 8292+/-3714 Euro; 5-6 ==> 8908+/-3480 Euro; 7-8 ==> 10,462+/-6123 Euro; 9-10 ==> 13,711+/-12,634 Euro; >10 ==> 21,353+/-18,507 Euro. Excluding EuroSCORE from the preoperative logistic model, age, preoperative creatinine, critical condition, ejection fraction, re-operation and sex were independently correlated with costs. CONCLUSIONS: From our data the EuroSCORE model developed to predict (30-day postoperative) hospital mortality could be used to predict direct operative costs and identify patients with different levels of resource consumption.
Pintor et al. (Tue,) conducted a observational in Open heart surgery (n=488). EuroSCORE model was evaluated on Direct variable costs (3.5% increase per score point, 95% CI 2.3-4.7, p=<0.0001). The EuroSCORE model significantly predicted direct operative costs in patients undergoing open heart surgery, with costs increasing by 3.5% (95% CI 2.3-4.7; P<0.0001) for each 1-point rise in score.
