Abstract
HYPOTHESIS: Surgeon-directed institutional peer review, associated with positive physician feedback, can decrease the morbidity and mortality rates associated with carotid endarterectomy. DESIGN: Case series. SETTING: Tertiary care university teaching hospital. PATIENTS/ INTERVENTIONS: All patients undergoing carotid endarterectomy at our institution during a 5-year period ending August 1998. RESULTS: Stroke rate decreased from 3.8% (1993-1994) to 0% (1997-1998). The mortality rate decreased from 2.8% (1993-1994) to 0% (1997-1998). Length of stay decreased from 4.7 days (1993-1994) to 2.6 days (1997-1998). The total cost decreased from $13,344 (1993-1994) to $9548 (1997-1998). CONCLUSIONS: An objective, confidential peer review process that provides ongoing feedback of performance to surgeons and documents that performance in relationship with that of peers seems to be effective in reducing the morbidity and mortality rate associated with carotid endarterectomy. In addition, the review process lowered the hospital cost of performing carotid endarterectomy.
