WebFeb 21, 2024 · A deterministic one-way sensitivity analysis of ICERs is shown in Figure 4. Both 5-year and lifetime ICERs were significantly influenced by RFA cost; 5-year ICERs were more sensitive to procedure costs than lifetime ICERs. The 5-year ICERs were about equally sensitive to variations in discount and utility weights. WebObjectives: Monte Carlo microsimulations have gained increasing popularity in decision-analytic modeling because they can incorporate discrete events. Although deterministic sensitivity analyses are essential for interpretation of results, it remains difficult to combine these alongside Monte Carlo simulations in standard modeling packages without …

WebJul 27, 2024 · Probabilistic sensitivity analysis (PSA) demonstrates the parameter uncertainty in a decision problem. The technique involves sampling parameters from their respective distributions (rather than simply using mean/median parameter values). Guidance in the literature, and from health technology assessment bodies, on the number of … WebNov 30, 2012 · Deterministic sensitivity analysis should also be used to test the impact of potential bias resulting from the selection or exclusion of data sources for key model parameters. Consideration can be given to including structural assumptions and the inclusion or exclusion of data sources in probabilistic sensitivity analysis. In this case …
