In the evolving landscape of healthcare innovation, Real-World Evidence (RWE) is transforming how medical devices and pharmaceuticals are evaluated, adopted, and reimbursed. While randomized controlled trials (RCTs) remain essential for regulatory approval, RWE offers complementary insights into how products perform in actual clinical settings-providing a more holistic view of safety, efficacy, and value.
What is Real-World Evidence?
Real-World Evidence refers to clinical evidence derived from the analysis of Real-World Data (RWD)-data gathered outside traditional clinical trials. Sources include:
- Electronic health records (EHRs)
- Patient registries
- Insurance claims and billing data
- Digital health tools and wearables
- Patient-reported outcomes and observational studies
RWE helps answer critical questions that RCTs alone cannot: How does a medical product perform across diverse patient groups, in varied care environments, and over time?
Why RWE Matters in Device and Drug Development
Challenges of Traditional Trials:
- Limited Generalizability: Trial populations may not reflect real-world demographics, comorbidities, or behaviors.
- Controlled Environments: RCTs often exclude real-world variables like clinician variation or patient adherence.
- High Cost & Duration: Especially for post-market surveillance or rare conditions.
RWE complements RCTs by offering insight into effectiveness (not just efficacy), long-term use, safety in broader populations, and practical adoption challenges.
RWE Applications in Medical Device & Drug Trials
| Application Area | Medical Devices | Drugs |
| Regulatory Approval | Supports CE marking under EU MDR with performance data | Complements RCTs for EMA regulatory decisions |
| Post-Market Surveillance | Required under EU MDR for continued safety monitoring | Supports pharmacovigilance and risk-benefit updates |
| Health Technology Assessment (HTA) | Demonstrates real-world value and usability | Informs reimbursement decisions via cost-effectiveness |
| Clinical Practice Improvement | Tracks usability, adherence, and user training needs | Assesses treatment outcomes and optimizes dosing |
| Study Design Optimization | Informs device iteration and user interface design | Enhances trial inclusion criteria and endpoints |
The Dutch and European Context
The Netherlands plays a leading role in advancing the use of RWE:
- Dutch National Data Warehouse (LDR, DHD) facilitates structured RWD sharing across institutions.
- ZIN (Zorginstituut Nederland) considers RWE in HTA and reimbursement decisions.
- European Health Data Space (EHDS) supports secure, interoperable data use for innovation and regulation across the EU.
For both medical devices and drugs, regulatory frameworks (EU MDR 2017/745 and EU CTR 536/2014) are increasingly encouraging or requiring RWE integration-especially in post-market settings.

✅ Value Communication
Translating real-world findings into value dossiers and stakeholder engagement materials that resonate with clinicians, payers, and patients.
Conclusion
RWE is no longer a “nice-to-have” – it is a strategic necessity in today’s evidence ecosystem. For medical devices and drug innovations to achieve real-world success, data must go beyond the lab and into lived patient experience.
At Lex Clinical, we ensure your innovations are supported by rigorous, relevant, and regulatory-aligned Real-World Evidence that drives both approval and adoption.
