Abstract T P14: In-Hospital Cost Analysis of the Addition of Hyperacute MRI for Selection of Patients for Endovascular Stroke Therapy
2015
Background: Patient selection is important for acute endovascular stroke therapy. We previously reported that a hyperacute MRI protocol for patient selection was associated with decreased utilization of endovascular stroke therapy and improved outcomes. A cost analysis comparing the pre and post-MRI protocol periods was performed to determine if the previous findings translated into cost savings. Methods: We retrospectively identified patients considered for endovascular stroke therapy from January 2008 to August 2012 who were ≤8 hours from stroke symptoms onset. Prior to April 30, 2010 selection was based on results of the CT/CTA alone (pre-hyperacute), whereas afterwards selection was based on results of MRI (hyperacute MRI). Demographic, outcomes and financial information was collected. Log-transformed average daily direct costs were regressed on time period. The regression model included demographic and clinical covariates as potential confounders. Multiple imputation was used to account for missing d...
