Barbosa et al. Complications of CABG and hospital expenses Int J Cardiovasc Sci. 2019;32(1)28-34 Original Article The mean expenditure of hospitalization was R$ 22,647.24, with a median of R$ 14,772.98 and standard deviation of R$ 28,105.66. In patients with any complication, corresponding to 97 individuals (40.4%), the mean expenditure was R$ 35,400.28, with standard deviation of R$ 40,509.47, and in those without complications, corresponding to 143 individuals (59.6%), the average expenditure was R$ 13,996.57, with standard deviation of R$ 5,800.61 (p < 0.001). However, the complications and their associated costs may vary according to each category. The 17 patients who evolved to bleeding, had a mean hospital expenditure of R$ 37,196.45 (SD = R$ 25,855.71), whereas the 223 patients without bleeding showed an expenditure of R$ 21,538.10 (SD = R$ 28,014.13) (p < 0.021). The 27 patients with arrhythmia had an average expenditure of R$ 31,760.52 (SD = R$ 22.416,23), whereas the 213 patients without arrhythmia showed an average expenditure of R$ 21,492.03 (SD = R$ 28,583.01) (p < 0.074). The 37 patients who developed cardiovascular complications showed an expenditure of R$ 45,899.94
