Strategic Recommendations for Optimal Data Access
Multi-Source Approach:
- Depth + Breadth Strategy: Combine one curated registry (for depth) with MAUDE or CMS claims (for breadth)
- Complementary Sources: Use free databases while DUA applications are processed
- Validation Opportunities: Cross-reference findings across multiple data sources
- Hypothesis Refinement: Public sources help refine research questions before expensive data acquisition
Cost-Effective Strategies:
- Start with Free Sources: MAUDE and ClinicalTrials.gov provide immediate insights
- Manufacturer Collaboration: Align research with industry priorities for free data access
- Academic Partnerships: Join existing studies rather than purchasing independent access
- Phased Approach: Use pilot studies to justify larger data investments
Quality Considerations:
- Data Completeness: Understand missing data patterns and follow-up rates
- Selection Bias: Account for registry participation patterns
- Temporal Trends: Consider changes in practice patterns over study periods
- International Generalizability: Supplement U.S. data with international sources
