check_ds_dsdecod_dsstdtc: Check DS with death record but no death date

In sdtmchecks: Data Quality Checks for Study Data Tabulation Model (SDTM) Datasets

Check DS with death record but no death date

Description

This check looks for patients in DS who have a record indicating death but no corresponding record with death date in DS. For example, "Survival Follow Up" records often have no death dates, so for a data cut to be applied properly, you have to impute that missing death date from another record where its not missing (e.g. Study Discon form)

Usage

check_ds_dsdecod_dsstdtc(DS)

Arguments

DS	Disposition SDTMv dataset with variables USUBJID, DSDECOD, DSSCAT and DSSTDTC

Value

Boolean value for whether the check passed or failed, with 'msg' attribute if the test failed

Examples

DS <- data.frame(STUDYID = rep(1, 5),
                 USUBJID = c(1, 1, 1, 2, 3),
                 DSDECOD = c("DEATH", "DEATH", rep("", 3)),
                 DSSCAT = LETTERS[1:5],
                 DSSTDTC = c("", "2016-01-01", "", "", "2016-01-02"),
                 stringsAsFactors = FALSE)
