Sensitivity Analysis
SENSITIVITY
Sensitivity analyses relating to methodological uncertainties (Changes in unit costs reflected iRARC surgery times being shorter than those observed in iROC, with the greatest changes to the ICER; a 10% reduction showed that iRARC was dominant and had a 61.9% chance of being cost-effective at £20 000 (US $28 860) per QALY gained. The estimated changes in robot life expectancy and throughput yielded smaller changes to the ICER. Lower ward costs that may better reflect marginal cost savings yielded only small changes to the ICER. The results appear generalizable to higher- and lower-cost hospitals, with the use of United Kingdom upper and lower quartile costs yielding a small change to the ICERs. These results are shown in
