How Patient Registries Drive Real-World Evidence—and Why It Matters

Last updated on

A patient takes a medication. They don’t react like they did in the trial data. The dosage needs adjusting. A comorbidity complicates things. This is real-world care—and it often looks very different from clinical trial conditions.
That’s where real-world evidence (RWE) comes in. It’s the growing body of data collected outside controlled studies, offering insights into how treatments, protocols, and diseases behave in the actual day-to-day of medicine.
And at the heart of this shift? Patient registries.

From Research to Reality

Clinical trials are rigorous, but narrow. They often exclude patients with multiple conditions, social barriers, or varied demographics. This means the "average patient" in real life isn’t always reflected in trial results.
Patient registries fill that gap. By tracking patient experiences over time—in hospitals, outpatient clinics, and even remote settings—registries collect data on what’s really happening:

  • Treatment effectiveness across diverse populations
  • Long-term safety signals
  • Disease progression in uncontrolled environments
  • It’s evidence that reflects the complexity of care.

Why Real-World Evidence Matters

RWE is gaining traction not just with researchers, but with policymakers and payers. Regulatory bodies like the FDA and EMA are increasingly using RWE to support:

  • Drug approvals
  • Label expansions
  • Reimbursement decisions

In fact, a recent analysis showed that over 40% of new FDA approvals in the past three years included real-world data.
For hospitals and care systems, this means registries aren’t just for internal tracking—they’re strategic assets that support research, funding, and clinical innovation.

Who Benefits from Registry-Driven RWE?

  • Clinicians get insights on how their peers treat complex cases.
  • Researchers gain access to larger, more varied datasets.
  • Public health agencies track population-level trends in near real time.
  • Patients benefit from treatments guided by people like them—not just ideal study subjects.

It’s a more inclusive, more accurate picture of care.

Looking Ahead

Real-world evidence isn’t just a trend—it’s becoming foundational to how healthcare evaluates effectiveness, designs policy, and allocates resources. Patient registries are a direct path into this future.
The question for healthcare organizations isn’t whether to collect data. It’s whether the data they collect can actually answer the right questions.
With thoughtfully built registries, the answer can be yes.

Next Step

Evaluate your existing registry or plan your next one with real-world use in mind. Consider:
What kinds of decisions do you want your data to support?
Are your fields, formats, and systems set up to capture that story?
Is your registry ready to do more than report—it’s ready to reveal?
Because healthcare isn’t lived in controlled trials. It’s lived in the real world—and your data should reflect that.

ICD-10, ICD-11, SNOMED CT, and Code Mapping: Everything You Need to Know

ICD-10, ICD-11, and SNOMED CT are essential coding systems in healthcare, each serving different purposes—from billing and public health tracking to detailed clinical documentation. To bridge these systems, diagnostic code mapping translates clinical terms between terminologies like SNOMED and ICD. This ensures accurate data exchange, faster reimbursement, and better decision support. Understanding and implementing proper mapping strategies is key to building interoperable, efficient healthcare systems.

How to Simplify ICD and SNOMED Interoperability Across Systems

ICD and SNOMED serve different roles in healthcare—one for billing and reporting, the other for clinical documentation and decision support. Bridging these systems is essential for accurate data exchange, consistent coding, and reliable analytics. This blog outlines five key strategies for simplifying interoperability: defining use-case-driven mapping, implementing real-time bidirectional translation, validating mappings with real clinical data, accounting for diagnostic context and hierarchy, and maintaining versioned, regularly updated maps. A thoughtful, tech-enabled mapping approach ensures diagnostic data is understood the same way across systems—supporting better care, compliance, and collaboration.
