PURPOSE: The EuroSCORE has been an integral part of our pre-surgical workup among open heart surgery patients. This study sought to assess the relationship between categorized cost and EuroSCORE among patients undergoing cariac surgery.
METHODS: We retrospectively reviewed 1,560 consecutive adult cardiac surgery cases for clinical and financial data. Cases were categorized as valve surgery (A; n=432), CABG following cardiac catheterization and or catheter intevention during the same admission (B; n=693), and elective CABG (n=435). Person correlation coeficiants were calculated for each of the operative categories. The severity of EuroSCORE was stratified into mild, 0-2; moderate, 3-5, and severe, 6+.
RESULTS: The severity of EuroSCORE correlated well with direct (r=0.36), pharmacy (0.24) and blood bank costs (0.22); p<0.001. Stratified by operative category, the EuroSCORE also correlated well; group A (r2=0.37, 0.24, 0.33), group B (r2 =0.41, 0.28, 0.28) and group C (r2 =0.35, 0.26, 0.10) for mild, moderate, and severe EuroSCORE category, respectively. Increased EuroSCORE resulted in higher direct cost in all groups of patients. The largest increase in direct cost (233%) was documented for group B patients when EuroSCORE changed from mild to moderate.
CONCLUSION: We have documented that in our institution the additive EuroSCORE algorithm could be used to predict cost.
CLINICAL IMPLICATIONS: The EuroSCORE algorithm can be used to predict operative costs and identify patients with different levels of resource consumption.
