Abstract
Objective The current study evaluated all-cause 30-day readmissions after carotid endarterectomy. Methods Patients undergoing carotid endarterectomy were selected from the Cerner Health Facts® database using ICD-9-CM procedure codes from their index admission. Readmission within 30 days of discharge was determined. Chi-square analysis determined characteristics of the index admission (demographics, diagnoses, postoperative medications, and laboratory results) associated with readmission. Multivariate logistic regression models were used to identify characteristics independently associated with readmission. Results In total, 5257 patients undergoing elective carotid endarterectomy were identified. Readmission within 30 days was 3.1%. After multivariable adjustment, readmission was associated with end-stage renal disease (OR: 3.21, 95% CI: 1.01–10.2), hemorrhage or hematoma (OR: 2.34, 95% CI: 1.15–4.77), procedural complications (OR: 3.07, 95% CI: 1.24–7.57), use of bronchodilators (OR: 1.48, 95% CI: 1.03–2.11), increased Charlson index scores (OR: 1.22, 95% CI: 1.08–1.38), and electrolyte abnormalities (hyponatremia < 135 mEq/L (OR: 1.69, 95% CI: 1.07–2.67) and hypokalemia less than 3.7 mEq/L (OR: 2.26, 95% CI: 1.03–4.98)). Conclusions Factors associated with readmission following carotid endarterectomy included younger age, increased comorbidity burden, end-stage renal disease, electrolyte disorders, the use of bronchodilators, and complications including bleeding (hemorrhage or hematoma). Of note, in this real-world study, only 40% of the patients received protamine, despite evidence-based literature demonstrating the reduced risk of bleeding complications. As healthcare moves towards quality of care-driven reimbursement, physician modifiable targets such as protamine utilization to reduce bleeding are greatly needed to reduce readmission, and failure to reduce preventable physician-driven complications after carotid interventions may be associated with decreased reimbursement.
