Insights
The average cost for coronary artery bypass grafting was US$2,784.98. Higher costs were associated with more grafts, with three to five grafts costing more than one or two.
Area of Science:
- Cardiovascular Surgery
- Health Economics
Background:
- Coronary artery bypass grafting (CABG) is a common surgical procedure for coronary artery disease.
- Understanding the cost drivers of CABG is crucial for healthcare management and resource allocation.
Purpose of the Study:
- To evaluate the hospital costs of elective coronary artery bypass grafting.
- To determine the relationship between the number of grafts and the overall cost of the procedure.
Main Methods:
- A prospective descriptive study was conducted with 103 elective coronary artery bypass grafting patients.
- Data on costs were collected during the preoperative, intraoperative (operating room), and postoperative periods.
- Patients with emergency conditions, other heart conditions, or reoperations were excluded.
Main Results:
- The average cost per CABG procedure was R$6,990.00 (US$2,784.98).
- Procedures involving three to five grafts incurred significantly higher average costs (R$7,148.05) compared to those with one to two grafts (R$6,659.29) (p < 0.05).
Conclusions:
- The operating room represented the highest cost component (R$4,627.97).
- Early postoperative care also contributed significantly to the overall cost (R$1,221.39).
- Costs increased with a higher number of bypass grafts performed.
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).
