Abstract 58. Single-Stage versus Two-Stage Arteriovenous Loop Microsurgical Reconstruction: An Evidence Based Review of the Literature and Analysis of Institutional Experience

RESULTS: The decision tree shows the associated QALYs, costs and probabilities used to calculate the ICUR of $3,699/QALY with gain of 2.7 QALYs at an additional cost of $9,987 proving that LVOS is cost-effective. One-way sensitivity analysis showed that LVOS became cost-ineffective when its clinical effectiveness had a QALY of less than 30.187. Probabilistic sensitivity analysis using Monte-Carlo simulation showed that even with varying multiple variables at once, results tended to favor our conclusion.
