add_outcomes: Add outcome columns to a dataset

Description

add_death(), add_serious(), and add_fup() create outcome columns in a vigibase dataset (typically demo), using data from the out and followup tables. These functions handle both in-memory and out-of-memory (Arrow) tables.

Usage

add_death(.data, out_data, col_name = "death")
add_serious(.data, out_data, col_name = "serious")
add_fup(.data, fup_data, col_name = "fup")

Value

A dataset with the new outcome column.

Arguments

.data

The dataset to update (usually demo).

out_data

A data.frame containing the outcome data (usually out).

col_name

A character string. Name of the new column. Defaults to "death", "serious", or "fup" respectively.

fup_data

A data.frame containing the follow-up data (usually followup).

Details

• add_death() adds a column indicating whether the case resulted in death (i.e., Seriousness == "1" in the out table). Cases with no outcome data are coded NA. Cases with outcome data but no death are coded 0. Cases with death are coded 1.

• add_serious() adds a column indicating whether the case was serious (i.e., Serious == "Y" in the out table). Cases with no outcome data are coded NA. Cases with outcome data but not serious are coded 0. Serious cases are coded 1.

• add_fup() adds a column indicating whether the case has a follow-up (i.e., UMCReportId appears in the followup table). Cases with a follow-up are coded 1. Others are coded 0.
