Abstract

Purpose: New techniques in the management of extracranial carotid occlusive disease have focused attention on the outcome and economics of carotid endarterectomy (CEA). Changing practice patterns for CEA must be assessed to allow accurate comparisons. The purpose of this study was to evaluate the effect of practice modifications related to CEA on patient outcome and cost data. Methods: Data on patients undergoing CEAs at a single institution from fiscal year 1992 to 1998 were prospectively collected and entered into a computerized database. Records were reviewed for patient demographics and outcome with regard to stroke and death. Selected years that corresponded to transitions in perioperative management were audited for complete hospital financial information from. Results: We performed 960 CEAs during the study period, with a combined stroke and death rate of 1.1%. Inflation-adjusted hospital costs per patient in 1998 dollars for the years 1992, 1996, and 1998 were $5494, $4476, and $3350, respectively. In 1998, costs for patients who required arteriography were $1825 greater than those operated on during duplex scan examination alone in 1998. Statistically significant differences occurred in the year-to-year comparisons in the use of arteriography, intensive care unit monitoring, same day admissions, and length of stay. There were no statistically significant differences in the stroke and death rate between years. Conclusion: Practice changes related to CEA have resulted in significant savings without detriment in patient outcome. Comparisons between CEA and endovascular techniques will need to be evaluated within this context. Given these advances in perioperative management, it will be difficult to justify carotid stenting on the basis of current economic considerations.
