We investigated the association between the Revised Cardiac Risk Index (RCRI) and postoperative outcomes in patients undergoing non-cardiac surgery.
The predictive value of the RCRI for the risk of perioperative complications, length of hospital stay and hospital cost were evaluated from a prospective cohort of 119 patients aged a parts per thousand yen65 years undergoing elective major digestive, breast or vascular surgery.
Comparing three groups RCRI 0, 1 and a parts per thousand yen2, the morbidity rates were 0, 30 and 68 %; the median length of hospitalization was 5, 14 and 28 days; and the median cost was 665,000, 1,480,000 and 2,160,000 yen, respectively. The mortality rate was 0 % in all groups. The RCRI 0 group included only non-high-risk (breast and peripheral vascular) surgeries. In addition, comparing the two groups by excluding non-high-risk surgeries (RCRI 1 and a parts per thousand yen2), the median morbidity rates were 31 and 67 %, the median length of hospitalization was 15 and 28 days, and the median cost was 1,550,000 and 2,130,000 yen, respectively. The RCRI score was the only independent predictor of the perioperative complications.
In the case of non-cardiac surgery, the RCRI can identify patients at higher risk of perioperative complications, a prolonged hospital stay and higher hospital cost.
