The Economic Cost of Elective Carotid Endarterectomy

Cost awareness and accountability for the use of health care resources have become major issues for clinicians. In order to identify the economic costs associated with carotid endarterectomy (CEA), a retrospective review of 50 elective CEA between May 1993 and April 1994 was undertaken. Despite our belief [based on the Australian National Diagnostic Related Groupings (ANDRG)], that our resource utilization had been refined to produce a median length of stay significantly below the New South Wales (NSW) State average, this study has identified several areas of non-productive expenditure. The mean cost of CEA per patient was $7053. This figure includes non-productive expenditure of $793 per patient in the pre-operative period and $395 per patient in the postoperative period. If these costs, which did not contribute to patient care, were removed the mean cost of CEA would be $5865. The major causes of non-productive resource utilization included prolonged pre-operative stay, duplicated or omitted investigations, as well as the use of the Intensive Care Unit for patient monitoring in the postoperative period.
