OBJECTIVES: Post-operative readmission is associated with increased morbidity and mortality. We evaluated risk factors for readmission and post-discharge mortality following carotid endarterectomy (CEA) in the ACS-NSQIP.
METHODS: All patients undergoing CEA without concurrent cardiac procedure in the 2011 NSQIP were identified. Independent predictors of 30-day readmission and post-discharge mortality were determined using multivariable logistic regression.
RESULTS: We identified 8,836 patients (38% symptomatic) undergoing CEA with readmission occurring in 667 (7.5%; symptomatic: 10%; asymptomatic: 7%; p<.01). Post-operative stroke rate was 1.2% (n=107) with 36% taking place post-discharge. Thirty-day mortality rate was 0.9% (n=80) with 45% happening post-discharge. Overall complication rate was 9.4%. Twenty-seven percent of complications occurred post-discharge with 70% of these undergoing readmission. Strongest independent predictors of readmission included OR take-back (OR: 9.2; 95% CI: 7.1-12.0), preoperative nursing home residence (OR: 2.7; 95% CI: 1.6-4.5), symptom status (OR: 1.4; 95% CI: 1.1-1.8), underweight (OR: 1.8; 95% CI: 1.1-2.9), CKD (OR: 1.3; 95% CI: 1.1-1.5) and anemia (OR: 1.5; 95% CI: 1.1-2.2).
CONCLUSIONS: Half of post-operative deaths and a quarter of complications occur post-discharge with post-discharge complications often leading to readmission. Patient selection and close follow up may play a role in mitigating adverse events following CEA.
