Abstract

Background and Objectives Numerous studies of various populations and diseases have shown that unplanned 30-day readmission rates are positively correlated with increased morbidity and all-cause mortality. In this study we aim to provide the rate and predictors of 30-day readmission in patients undergoing treatment for unruptured intracranial aneurysms.

Methods This is a retrospective study of 525 patients presenting for aneurysm treatment between 2017 and 2022. All patients that were admitted and underwent a successful treatment of their unruptured intracerebral aneurysms were included in the study. The primary outcome was the rate and predictors of 30-day readmission.

Results The rate of 30-day readmission was 6.3% and the mean duration to readmission was 7.8 days ± 6.9. On univariate analysis, factors associated with 30-day readmission were antiplatelet use on admission (OR:0.4, p=.009), hemorrhagic rupture (OR:15.8, p=0.007), surgical treatment of aneurysms (OR=2.2, p=0.035), disposition to rehab (OR:9.5, p<.001), and increasing length of stay (OR:1.1, p=.0008). On multivariate analysis, antiplatelet use on admission was inversely correlated with readmission (OR:0.4, p=0.045) while hemorrhagic rupture (OR: 9.5, p=0.04) and discharge to rehab (OR: 4.5, p=0.029) were independent predictors of 30-day readmission.

Conclusion In our study, risk factors for 30-day readmission were aneurysm rupture during the hospital stay and disposition to rehab while the use of antiplatelet on admission was inversely correlated with 30-day readmission. Though aneurysm rupture is a non-modifiable risk factor, more studies are encouraged to focus on the correlation of antiplatelet use and rehab disposition with 30-day readmission rates.
