Sensitivity analysis
To validate the results a one-way sensitivity analysis was performed.
The value of variables changed by 20% and the tornado diagram was
plotted. As shown in Figures 1, ICER in clinical outcomes including
patients pain score, incidence of bleeding, incidence of blood
transfusion and re-operation had the highest sensitivity to the
inpatient effectiveness and DCT effectiveness and the lowest level of
sensitivity to the cost of DCT.
