Abstract

Objective: To examine adherence in clinical practice to the American College of Cardiology/American Heart Association (ACC/AHA) guideline recommendations of observing a 5-day waiting period after clopidogrel administration before undergoing coronary artery bypass graft (CABG) surgery and to examine the costs of waiting. Methods: This retrospective study used a nationwide inpatient database (Solucient ACTracker) to identify patients who were admitted for acute coronary syndrome (ACS), and who had same-stay CABG. Cost of additional days of stay was estimated using regression analysis. Results: The recommended 5-day waiting was adhered to in 16.9% (n=3,809) of patients. The percentage of patients with ACS undergoing CABG surgery on day 0 was 14.6%. Adherence to the waiting was higher for teaching and rural hospitals; and in female and elderly patients and urgent admissions. Conclusions: The recommended 5-day waiting for CABG surgery after clopidogrel treatment is poorly adhered to in clinical practice. This study was unable to determine specific reasons for the low adherence; however, there may be a compromise between the clinically urgent need for revascularisation and increased risk of bleeding, as well as economic costs associated with waiting. The cost of an additional hospital day in this group of patients was approximately £1,400 per day or £7,000 for 5 days. Thus, a full 5-day wait would have a significant economic impact on hospital costs.
