Mp17-02 repair Rate and Associated Cost of Reusable Flexible Ureteroscopes: A Systematic Review and Meta-Analysis

Abstract

INTRODUCTION AND OBJECTIVE: Many institutions rely on historical data to guide preoperative type and screen (T/S) requirements. Our objective was to evaluate the cost-effectiveness of obtaining preoperative T/S for common urological procedures and determine patient and hospital factors associated with receiving blood transfusions.METHODS: Retrospective database analysis of the 2006-2015 National (Nationwide) Inpatient Sample (NIS) was performed to identify patients undergoing a variety of urological procedures where T/S is generally obtained. A total of 4,113,144 cases were identified. Transfusion rates were then determined from NIS data, and multivariate regression analyses was used to identify factors associated with transfusions. A cost-effectiveness analysis was performed to determine the incremental cost-effectiveness ratio (ICER) of obtaining preoperative T/S to prevent an emergency-release transfusion (ERT), with a willingness-to-pay threshold of $1,500.RESULTS: On multivariate modeling, all Elixhauser comorbidities with the exception of obesity were significant associated with transfusion Some examples included chronic blood loss anemia (OR,
