In the past decade, expected in-hospital length of stay (LOS) after carotid endarterectomy (CEA) has decreased from 4 days to 1. Long LOS is associated with known complications and factors affecting severity of the patient's condition. Factors affecting an intermediate stay of 2 to 4 days need further clarification. The vascular registry at Jobst Vascular Center includes data on manifestation of disease; cardiovascular history; operation and discharge dates; surgeon; surgical details such as patching, shunting, and completion arteriography; and complications. Univariate chi-square and ANOVA and multivariate logistic regression were applied to analyze 638 CEAs performed in 1998, 1999, and 2000. Statistical significance was at a p value less than 0.05 (two-sided). Overall morbidity rate was 8.2% with three (0.5%) inhospital neurologic complications and one death for a 0.16% mortality rate. Fifty-eight percent of the patients were discharged in 1 day. Patients staying 1 day were 3 years younger. Female gender and prior cerebrovascular accident were factors extending LOS to 2 and 3 days. History of angina, heart failure, valve disease, and vein patch or no patch contributed to LOS of 3 or 4 days. Completion arteriography had an association with LOS of 2 days. The relative percentage of patients with complications increased with LOS. No significant relationship was found for symptoms, smoking, myocardial infarction, atrial fibrillation, cardiac revascularization, or surgeon. Insulin-treated diabetes mellitus, cardiac risk factors, cerebrovascular accident, and vein patch or no patch correlated with prolonged hospitalization. Factors were identified that may alter a clinical pathway designed for discharge 1 day after CEA. Focused management of patients with cardiac and cerebrovascular accident history or requiring vein patch and a better understanding of CEA in women may further increase the percentage of patients discharged 1 day after CEA.
