Fig 2. Variation in the net monetary benefit of the intraoperative prevention strategy according to model inputs. The
net monetary benefit of prevention was derived using a monetary value of $50,000 for 1 quality-adjusted life year. The
positive values for net monetary benefit of prevention indicate that the intraoperative prevention strategy is cost effective
relative to current practice. All horizontal bars represent variation in the net benefit when model inputs were varied
using values displayed to the left and right of the bars. Input values used in the base case analysis are displayed in parentheses
at the end of the labels to the left of the plotting area. For example, the top horizontal bar displays changes in
the net benefit of prevention from $13 to $116 when the intraoperative incidence was varied from 0.32% to 2.79%. The
intraoperative incidence used in the base case analysis was 1.1%. I-O, Intraoperative; PrU, pressure ulcer.
