check_ds_dsdecod_dsstdtc: 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)

Value

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

Arguments

DS

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