Abstract

Background and Objectives The 30-day readmission rate has emerged as a metric of quality care and is associated with increased healthcare expenditure. We aim to identify the rate and causes of 30-day readmission after mechanical thrombectomy and provide the risk factors of readmission to highlight high risk patients that may require closer care.

Methods This is a retrospective study from a prospectively maintained database of 703 patients presenting for mechanical thrombectomy between 2017 and 2023. All patients who presented with a stroke and underwent a mechanical thrombectomy were included in the study. Patients who were deceased on discharge were excluded from the study.

Results Our study comprised of 703 patients, mostly females (n=402, 57.2%), with a mean age of 70.2 years ± 15.4. The most common cause of readmission was cerebrovascular events [stroke (n= 21, 36.2%), intracranial hemorrhage (n=9, 15.5%), and TIA (n=1, 1.7%)].Other causes of readmission included cardiovascular events [cardiac arrest (n=4, 6.9%) and bradycardia (n=1, 1.7%)], and infection [ wound infection post- craniectomy (n=3, 5.2%), and pneumonia (n=1, 1.7%)], On multivariate analysis, independent predictors of 30-day readmission were history of smoking (OR: 2.2, 95% CI: 1.1–4.2) p=0.01), distal embolization (OR: 3.2, 95% CI: 1.1–8.7, p=0.03), decompressive hemicraniectomy (OR: 9.3, 95% CI: 3.2–27.6, p<0.01), and intracranial stent placement (OR: 4.6, 95% CI: 2.4–8.7) p<0.01).

Conclusion In our study, the rate of 30-day readmission was 8.3% and the most common cause of readmission was recurrent strokes. We identified a history of smoking, distal embolization, decompressive hemicraniectomy, and intracranial stenting as independent predictors of 30-day readmission in stroke patients undergoing mechanical thrombectomy.
