Description

Discounted total QALYs up to a defined time horizon. This is a simpler, alternative function. See S3 Method also available (total_QALYs).

Usage

1
2
calc_QALY(utility = NA, intervals = NA, age = NA, start_delay = 0,
  discount_rate = 0.035, utility_method = "add")

Arguments

utility

Vector of values between 0 and 1 (1 - utility loss)

intervals

Time intervals for each utility, usually whole year i.e. 1. This is useful for fractions of years at the start and end of the period. However, since we may not know this then may not be necessary.

age

Year of age

start_delay

What time delay to origin, to shift discounting

discount_rate

Default: 3.5% per year

utility_method

How to combine utilities. Default: add, or prod

Details

Uses the following formula, for year i:

∑ interval(i) * utility(i) * QoL(age(i)) * discount(i)

for i = 1, ..., time_horizon.
