HADDAD, Nagib et al. Hospital costs of coronary artery bypass grafting on elective coronary patients. Arq. Bras. Cardiol. [online]. 2007, vol.88, n.4, pp. 418-423. ISSN 1678-4170. http://dx.doi.org/10.1590/S0066-782X2007000400009.
OBJECTIVE: To assess hospital costs associated with coronary artery bypass grafting performed on elective coronary patients, and the relation of costs with the number of grafts. METHODS: Descriptive prospective study carried out at Instituto Dante Pazzanese de Cardiologia in April, May and June of 2005. Coronary patients of different ages and both genders were included. Emergency patients, patients with other associated heart conditions and reoperation cases were excluded. Appropriate forms for the operating room, early postoperative period and for the final period in the ward were developed for the initial hospitalization phase preoperatively. RESULTS: The procedure was performed on 103 patients, at an average cost of R$6,990.00 (US$2,784.98), at a minimum of R$5,438.69 (US$2,166.81), and maximum of R$11,778.96 (US$4,692.81); standard deviation was R$1,035.47 (US$412.54) and the confidence interval was 95%, ranging from R$6,790.33 - R$7,190.27 (US$2,705.31 - US$2,864.67). The total average cost for three to five bypass grafts was higher (R$7,148.05) than for one and two bypass grafts (R$6,659.29) and the difference was significant (p < 0.05). CONCLUSION: The highest average costs were in the operating room (R$4,627.97), and in the early postoperative period (R$1,221.39), followed by costs incurred in the ward after the early postoperative period (R$840.04) and by the initial preoperative period in the ward (R$300.90).
