Abstract

Abstract : INTRODUCTION: Cerebrospinal fluid shunting is the mainstay for intracranial hydrocephalus but has a high rate of surgical revision secondary to infections and blockage. Traditionally, the hospital stay is one day post-operative for a non-complicated shunt revision. However, in the appropriate population we believe the same day discharge after a shunt revision is safe. METHODS: We perform a retrospective chart review of all shunt revisions performed at Penn State Milton S. Hershey Medical Center between 2014 and 2021. Patient characteristics were evaluated for the ideal demographics for same day discharge. We compared rates of emergency department visits, hospitalization, and revision at 30 and 90 days between same day discharge and control patients following shunt revision. Non-parametric, Logistic regression and Chi-squared testing was done for statistically significant with and without Propensity Score Matching. RESULTS: A total of 996 patient were examined with 56 (5.6%) patients being discharged on the same day as the surgery. On univariate analysis, patient with same day discharge were older (OR 1.019; 1.007-1.032), more like for distal shunt failure (OR 4.914; 2.792-8.649), more likely for elective surgery (OR 5.472; 2.346-12.763), and less likely to have visited the emergency department in the prior 30 d (OR 0.216; 0.112-0.413). On multivariate analysis, recent ED visit, elective surgery, and distal shunt failure remained significant. In unmatched data, same-day discharge patients had significantly less 30-day revisions (p=.035) but a comparable rate of 90-day revisions as well as 30-day and 90-day emergency room visits and hospitalization. Propensity-score matching compared 29 revisions in each group; all covariates were non-significant (p > 0.05) and all 30-day and 90-day outcomes were not significantly different. CONCLUSION: These findings validate the safety profile for same day discharge in post-operative shunt patients as well as describe the preferred characteristics of our patient cohort. Elective, distal shunt failure patients are preferred for early discharge post-operatively.
