Health economic evaluation method
In a cost-effectiveness analysis, the result is traditionally presented in terms of the incremental cost-effectiveness ratio (ICER). For the strategies being compared or evaluated, the ICER estimates the difference in costs (measured in monetary units) divided by the difference in effects, thus expressing the cost of achieving one more unit of the effect. In this analysis, time until success of treatment was measured as time from first to last test. Since there was no significant difference in duration of phototherapyWe performed sensitivity analysis by bootstrapping to acknowledge sampling uncertainty in both costs and effects. This procedure accounts for the variance in the study data by drawing repeated random samples with replacement of costs and effects from the intervention and control groups, with a sample size corresponding to the original sample. We drew 1000 sample pairs and estimated the average costs and effects for each. We also performed a deterministic sensitivity analysis, varying one variable while keeping the other constant, which allowed for uncertainty in cost estimations while facilitating generalizability to settings other than Sweden.
