Abstract
BACKGROUND: The association of Magnet hospital status with improved surgical outcomes remains an issue of debate. OBJECTIVE: To investigate whether hospitalization in a Magnet hospital is associated with improved outcomes for patients undergoing neurosurgical operations. METHODS: A cohort study was executed using all patients undergoing neurosurgical operations in New York registered in the Statewide Planning and Research Cooperative System database from 2009 to 2013. We examined the association of Magnet status hospitalization after neurosurgical operations with inpatient case fatality and length of stay (LOS). We employed an instrumental variable analysis to simulate a randomized trial. RESULTS: Overall, 190 787 patients underwent neurosurgical operations. Of these, 68 046 (35.7%) were hospitalized in Magnet hospitals, and 122 741 (64.3%) in non-Magnet institutions. Instrumental variable analysis demonstrated that hospitalization in Magnet hospitals was associated with decreased case fatality (adjusted difference, -0.8%; -95% confidence interval, -0.7% to -0.6%), and LOS (adjusted difference, -1.9; 95% confidence interval, -2.2 to -1.5) in comparison to non-Magnet hospitals. These associations were also observed in propensity score adjusted mixed effects models. These associations persisted in prespecified subgroups of patients undergoing spine surgery, craniotomy for tumor resection, or neurovascular interventions. CONCLUSION: We identified an association of Magnet hospitals with lower case fatality, and shorter LOS in a comprehensive New York State patient cohort undergoing neurosurgical procedures.
