COSTS ASSOCIATED WITH TRANSRADIAL ACCESS AND SAME-DAY DISCHARGE AFTER PERCUTANEOUS CORONARY INTERVENTION: A SYSTEMATIC REVIEW AND META-ANALYSIS

Abstract

AbstractIntroductionTransradial access for PCI (TRI) along with same day discharge (SDD) is associated with varying estimates of cost savings depending on the population studied, the clinical scenario and application to low-risk vs high-risk patients. A summary estimate of the true cost savings of TRI and SDD are unknown.MethodsWe searched the PubMed, EMBASE®, CINAHL® and Google Scholar® databases for published studies on hospitalization costs of TRI and SDD. Primary outcome of interest in all included studies was the cost saving with TRI (or SDD), inflation-corrected US$ 2018 values using the medical consumer price index. For meta-analytic synthesis, we used Hedges’ summary estimate (g) in a random-effects framework of the DerSimonian and Laird model, with inverse variance weights. Heterogeneity was quantified using the 12 statistic.ResultsThe cost savings of TRI from four US studies reported a consistent and significant cost saving associated with TRI after accounting for currency inflation, of US$ 992 (95% CI US$ 8501,134). The cost savings of SDD from six US studies, after inflation-correcting to the year 2018, were US$ 3,567.58 (95% CI US$ 2,303 –4,832).ConclusionsIn conclusion, this meta-analysis demonstrates that TRI and SDD are associated with mean cost reductions of by approximately US$1,000/patient and US$ 3,600/patient, respectively, albeit with wide heterogeneity in the cost estimates. When combined with the safety of TRI and SDD, this meta-analysis underscores the value of combining TRI and SDD pathways and calls for a wide-ranging practice change in the direction of TRI and SDD.
