recalculate_age_tx_start: Adjust age to treatment episode

In JayAchar/hisreportr: hisreportr: Automating MSF OCA EMR reporting

Description

In the OCA EMR, age is recorded once when people are registered in the database. Over time, people may initiate treatment for different diseases at different time points. Since age at treatment initiation is often required, the recorded value must be adjusted to represent the age when treatment starts.

Usage

recalculate_age_tx_start(x, start_var, categorise = TRUE)

Arguments

x	data frame including age at registration, treatment initiation date and patient registration date
start_var	define variable representing treatment initiation date
categorise	logical argument to flag whether to add a categorised age variable to simplify reporting

Details

This function is designed to generate an additional variable, age_recalculated, by adding time from registration to treatment initiation to the recorded age.

Value

data frame with additional variable age_recalculated alongside recorded age
