create_costmods: Create cost models

In InnovationValueInitiative/IVI-NSCLC: The IVI-NSCLC model

Description

Create a cost model for four cost categories: (i) treatment costs (i.e., drug acquisition and administration costs), (ii) inpatient medical costs, (iii) outpatient medical costs, and (iv) costs due to adverse events.

Usage

create_costmods(n = 100, struct, patients, ae_probs,
  params_costs_tx = iviNSCLC::params_costs_tx,
  params_costs_op = iviNSCLC::params_costs_op,
  params_costs_inpt = iviNSCLC::params_costs_inpt,
  params_costs_ae = iviNSCLC::params_costs_ae)

Arguments

n	The number of random observations of the parameters to draw.
struct	A model_structure object.
patients	A data table returned from create_patients.
ae_probs	An "ae_probs" object as returned by ae_probs.
params_costs_tx	Parameter estimates for treatment costs (i.e., acquisition and administration costs) in the same format as params_costs_tx.
params_costs_op	Parameter estimates for outpatient medical costs in the same format as params_costs_op.
params_costs_inpt	Parameter estimates for inpatient medical costs in the same format as params_costs_inpt.
params_costs_ae	Parameter estimates for adverse event costs in the same format as params_costs_ae.

Value

A list of objects of class "StateVals" from the hesim package.

Examples

# Treatment sequences
txseq1 <- txseq(first = "erlotinib",
                second = c("osimertinib", "PBDC"),
                second_plus = c("PBDC + bevacizumab", "PBDC + bevacizumab"))
txseq2 <- txseq(first = "gefitinib",
                second = c("osimertinib", "PBDC"),
                second_plus = c("PBDC + bevacizumab", "PBDC + bevacizumab"))
txseqs <- txseq_list(seq1 = txseq1, seq2 = txseq2)

# Patient population
pats <- create_patients(n = 2)

# Model structure
struct <- model_structure(txseqs, dist = "weibull")

## Cost models
n_samples <- 2
ae_probs <- ae_probs(n = n_samples, struct = struct)
costmods <- create_costmods(n = 2, struct = struct, patients = pats,
                            ae_probs = ae_probs)
