Abstract:
This study was undertaken to compare economic outcomes of off-pump coronary artery bypass grafting (off-pump CABG: OPCAB) and conventional CABG (CCABG). We reviewed the medical records of 5 patients with ischemic coronary disease (IHD) who underwent OPCAB and 5 patients with IHD who underwent CCABG. A hospital income which was based on a current Japanese health insurance system was indicated. There were significant differences in total cost (OPCAB = 208,200 +/- 7,383 yen versus CCABG = 324,300 +/- 10,290 yen, 35.8% decreased), costs of medical materials and transfusions (OPCAB = 14,760 +/- 3,270 yen versus CCABG = 87,540 +/- 3,326, 81.3% decreased) and charges of surgery and anesthesia (OPCAB = 130,400 +/- 1,853 yen versus CCABG = 147,650 +/- 4,167 yen, 12% decreased) OPCAB markedly reduces the cost of hospitalization. But charges of surgery and anesthesia of OPCAB seems to be valued properly in a current Japanese health insurance system.
