Figure 2

Tornado diagram of one-way sensitivity analyses. This figure plots each variable’s incremental cost-effectiveness ratio (ICER), or cost to achieve one additional quality adjusted life year (QALY), across the range of each variable’s values examined in the model. Ranges for each variable are reported and the direction of their influence on the ICER. The center line at an ICER of $32,483 represents the average ICER of all variables. Negative ICERs indicate that the POC Lactate Program is dominant when compared with the Usual Care Strategy at that particular value.

Note: CE, cost-effectiveness; ICU, intensive care unit; POC, point-of-care; QALY, quality-adjusted life year
