In twig: For Streamlining Decision and Economic Evaluation Models using Grammar of Modeling

Calculate Incremental Cost-Effectiveness Ratios (ICERs)

Description

This function calculates the Incremental Cost-Effectiveness Ratios (ICERs) for a set of strategies based on their costs and effects.

Usage

calculate_icers(payoffs_summary, col_names = c("cost", "utility"))

Arguments

payoffs_summary	A matrix or data frame containing the summary statistics of the payoffs. It must have columns for cost and utility.
col_names	A character vector specifying the names of the columns for cost and utility. Default is c("cost", "utility").

Value

A data frame with the following columns:

• decision: The name of the strategy.

• cost: The cost of the strategy.

• utility: The effect (utility) of the strategy.

• inc_cost: The incremental cost compared to the next less effective strategy.

• inc_utility: The incremental effect compared to the next less effective strategy.

• ICER: The Incremental Cost-Effectiveness Ratio.

• status: The dominance status of the strategy (ND = non-dominated, D = dominated, ED = extendedly dominated).

Examples

payoffs_summary <- matrix(c(100, 200, 0.5, 0.7), ncol = 2, 
                          dimnames = list(c("Strategy A", "Strategy B"), 
                                          c("cost", "utility")))
calculate_icers(payoffs_summary)
