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