Insights on the standardization of instruments within your organization
Experiences with implementation of 'Reason Not Performed' (QSREASND) in QS domains as outlined in Section 4.1.2.2 of the "Handling of Missing Data in Submitting Clinical Trial Datasets and Documentation for Clinical Outcome Assessments Using Item Response Theory" and Section 3.1.1.2 of the "Handling of Missing PRO Data Submitting Patient-Reported Outcome Data in Cancer Clinical Trials."
- How are you capturing QSREASND data? Is this incorporated in the Case Report Form (CRF) or within the electronic Clinical Outcome Assessment (eCOA) platform?
- Have our vendors been able and willing to add 'Reason Not Performed' (QSREASND) if it wasn't already included in the QS?
- Any considerations and learnings you can share from your experience with this implementation ?
