Figure 1. Sensitivity Analysis (Cost per Biphasic Anaphylaxis Episode Observed).

Figure 1.

A, Deterministic sensitivity analysis of risk for biphasic anaphylaxis (after complete resolution) is shown. If the risk for biphasic anaphylaxis exceeds 17% (dotted vertical line), then extended observation for 6 hours would cost less than $10 000 per case of biphasic anaphylaxis identified. B, Sensitivity analysis of direct hourly costs is shown. If the direct hourly cost of observation is less than $46 (dotted vertical line), 6-hour observation could be cost-effective (willingness-to-pay = $10 000 per observed biphasic anaphylaxis episode).
