summarize_ce: Summarize costs and effectiveness

In hesim: Health Economic Simulation Modeling and Decision Analysis

Summarize costs and effectiveness

Description

Summarize costs and quality-adjusted life-years (QALYs) given output simulated from an economic model. The summary output is used to perform cost-effectiveness analysis with cea() and cea_pw().

Usage

summarize_ce(costs, qalys, by_grp = FALSE)

Arguments

costs	Simulated costs by category (objects of class costs).
qalys	Simulated QALYs (objects of class qalys).
by_grp	If TRUE, then costs and QALYs are computed by subgroup. If FALSE, then costs and QALYs are aggregated across all patients (and subgroups).

Details

If mean costs and/or QALYs have already been computed (i.e., an average within a population), then there must be one observation for each discount rate (dr), PSA sample (sample), treatment strategy (strategy_id), and health state (state_id). Alternatively, there can be a column denoting a patient (patient_id), in which case outcomes will first be averaged across patients. A grp_id column can also be used so that outcomes are computed for each subgroup (if by_grp = TRUE); otherwise it is assumed that there is only one subgroup.

Value

An object of class ce.
