Age >or=75 years is associated with greater resource utilization following coronary artery bypass grafting

Area of Science:

• Cardiovascular Surgery
• Geriatric Medicine
• Health Services Research

Background:

• Coronary artery bypass grafting (CABG) is a common procedure for advanced coronary artery disease.
• The impact of advanced age on outcomes and resource use following CABG requires careful evaluation.

Purpose of the Study:

• To compare postoperative complication rates and resource utilization between elderly (>=75 years) and younger (<75 years) patients undergoing isolated CABG.
• To identify if advanced age is an independent predictor of adverse outcomes and increased resource use.

Main Methods:

• Retrospective review of prospectively collected data from 2936 patients undergoing first-time isolated CABG.
• Patients were stratified into two groups: <75 years (younger) and >=75 years (older).
• Major postoperative complications and resource utilization metrics (ICU length of stay, postoperative length of stay, total hospital length of stay) were analyzed.

Main Results:

• Elderly patients were more likely to be female and require urgent procedures.
• Significantly higher rates of major postoperative complications were observed in the elderly group (43.7% vs. 23.0%).
• Older patients experienced longer intensive care unit and postoperative hospital stays.

Conclusions:

• Age >=75 years is an independent predictor of longer postoperative length of stay after CABG.
• Elderly patients undergoing CABG demonstrate significantly higher complication rates and greater resource utilization compared to younger patients.
• These findings highlight the need for tailored perioperative management strategies for elderly patients undergoing CABG.
