Journal of Neurosurgery, Ahead of Print. OBJECTIVE Fragmentation of care has been recognized as a major contributor to 30-day readmissions after surgical procedures. The authors investigated the association of evaluation in the hospital where the original procedure was performed with the rate of 30-day readmissions for patients presenting to the emergency department (ED) after craniotomy for primary brain tumor resection. METHODS A cohort study was conducted, involving patients who were evaluated in the ED within 30 days after discharge following a craniotomy for primary brain tumor resection between 2009 and 2013, and who were registered in the Statewide Planning and Research Cooperative System (SPARCS) database of New York State. A propensity score–adjusted model was used to control for confounding, whereas a mixed-effects model accounted for clustering at the hospital level. RESULTS Of the 610 patients presenting to the ED, 422 (69.2%) were evaluated in a hospital different from the one where the original procedure was performed (28.9% were readmitted), and 188 (30.8%) were evaluated at the original hospital (20.3% were readmitted). In a multivariable analysis, the authors demonstrated that being evaluated in the ED of the original hospital was associated with a decreased rate of 30-day readmission (OR 0.64, 95% CI 0.41–0.98). Similar associations were found in a mixed-effects logistic regression model (OR 0.63, 95% CI 0.40–0.96) and a propensity score–adjusted model (OR 0.64, 95% CI 0.41–0.98). This corresponds to one less readmission per 12 patients evaluated in the hospital where the original procedure was performed. CONCLUSIONS Using a comprehensive
