The clinical and financial impact of port-access coronary revascularization

Insights
Port-access coronary bypass grafting (CABG) offers clinical benefits for select patients with coronary artery disease, including reduced ICU time and pain. However, this minimally invasive approach currently incurs higher institutional costs.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Surgery
Background:
- Coronary artery disease necessitates surgical intervention for many patients.
- Traditional coronary artery bypass grafting (CABG) involves median sternotomy.
- Advancements in surgical techniques aim to improve patient outcomes and recovery.
Purpose of the Study:
- To evaluate the clinical and financial outcomes of port-access coronary bypass grafting (CABG).
- To compare port-access CABG with standard median sternotomy CABG in terms of patient recovery and costs.
Main Methods:
- A cohort of 100 patients underwent port-access CABG.
- Clinical and financial data were compared to 531 patients who had standard median sternotomy CABG.
- Key outcome measures included ICU stay, complications, pain, and hospital costs.
Main Results:
- Port-access CABG showed no instances of aortic dissection, deep vein thrombosis, conversion to sternotomy, or death.
- Patients undergoing port-access CABG experienced shorter ICU stays, less atrial fibrillation, reduced transfusion needs, and lower pain scores.
- Despite similar lengths of stay, port-access CABG resulted in an average cost increase of $2703 per case.
Conclusions:
- Port-access CABG is a safe and effective technique for selected patients with coronary artery disease, offering significant clinical advantages.
- The current implementation of port-access CABG leads to increased institutional costs.
- Further evaluation is needed to optimize the cost-effectiveness of this minimally invasive approach.
Objective:
Port-access coronary bypass grafting (CABG)was performed in an attempt to impact the clinical course of patients with coronary artery disease.
Methods:
One hundred patients (56 men and 44 women) with a median age of 61 years underwent port-access coronary revascularization. The clinical and financial profiles of these patients were compared with fiscal year 1997 patients (n = 531) who underwent standard median sternotomy coronary bypass.
Results:
Preoperative clinical demographics were similar in both groups of patients. Among the port-access population there were no incidences of aortic dissection, deep vein thrombosis, conversion to median sternotomy, or death. Total time in the Intensive Care Unit (ICU), incidence of atrial fibrillation, transfusion requirements, and (subjective) pain rating at 28 days postoperatively were less in the port-access group. The average hospital cost per case was $2703.00 (US dollars) more in the port-access patients, despite a similar length of stay versus conventional sternotomy patients.
Conclusions:
Coronary bypass surgery can be performed safely with port-access technology with significant clinical benefits in selected patients. Currently these benefits are attained at a significant cost to the institution.
