check_qs_qsstat_qsreasnd {sdtmchecks}

Check to confirm that there is a reason for a questionnaire being marked as not done

Description

This code flags when QSSTAT Completion Status is marked as NOT DONE but QSREASND Reason Not Performed is not populated. Some but not all questionnaires in a study may collect Reason Not Performed information, so there may be instances of false positives in which no data correction is required. While QSREASND is a permissible variable, this scenario will be flagged in P21.

Usage

check_qs_qsstat_qsreasnd(QS)

Arguments

QS

Questionnaire SDTMv dataset with USUBJID, QSCAT, QSDTC, QSSTAT, QSREASND, VISIT (optional) variables

Value
