Query Management in Complex Study
This case highlights how adaptive protocol designs, while scientifically and ethically beneficial, introduced frequent interim DBLs that complicated data management and triggered time-sensitive re-work, particularly for sites. Although eCRF modules remained stable, changes to RBM algorithms and evolving data interpretations led to extensive re-SDV of previously frozen data and uncertainty in reassessing imaging results. This caused reopened eCRFs and unclear expectations for site teams. The case was resolved using our three-step approach:
Define the challenge with precision.
Problem Statement: Interim DBLs created significant and unclear workloads for sites and CRAs, threatening data quality and timelines.
Root cause
- Data Management adjusted RBM algorithms based on Biostatistics’ dry-run analyses, without validating changes at the global Study Team level.
- Sites, Data Management, and Imaging Adjudication struggled to agree on sufficient detail for imaging re-alignment.
- Query turnaround times did not account for regional time zone differences.
Root Cause Learning
- All members of the global Study Team must understand downstream data flow implications before RBM algorithm adjustments.
- Imaging reinterpretation requirements must be defined in DBL support material ahead of site preparations.
- Query turnaround expectations must reflect time zone realities.
Scope
- Align DBL scope across the global team, the local Study Managers, CRAs, and sites.
- Provide clear support material for CRAs and sites.
Resolution scenario
- Conduct extraordinary alignment meetings:
- The global Study Team with local Study Managers to align DBL scope requirements.
- Local Study Managers with CRAs and sites to operationalize the DBL plan locally.
Develop tailored, compliant solutions.
- Ensure site contracts account for expectations and potential additional work related to interim DBLs and adjustments to RBM algorithms in adaptive protocols.
- Capture alignment meeting input to streamline DBL scope.
- Update DBL preparation materials to describe data handling in detail.
- Train local Study Managers to cascade scope and details to CRAs and sites.
Deploy training, oversight, and anchoring.
- Update processes and reflect essentials in training.
- Launch updated DBL communication and training.
- Provide hyper-care during the early DBL period.
- Anchoring and handover.
- Centrally monitor query turnaround and re-issued queries.
- Capture lessons learned for continuous improvement.
- Reinforce thorough DBL scope descriptions in future studies.
- Transition long-term ownership to process owner.
Impact
- Improved DBL transparency and expectation management across stakeholders.
- Reduced site and CRA workload through realistic turnaround times and detailed guidance.
- Secured timely, high-quality DBLs and strengthened trust in adaptive designs.
