Randomized clinical trials follow strict protocols to evaluate medical treatments, but they don’t always reflect the range of experiences seen in routine care. Patients often have multiple conditions, providers may take different approaches, and outcomes can vary across settings.
Real world evidence (RWE) refers to insights generated from data collected during everyday clinical practice. This includes information from electronic health records, insurance claims, registries, and patient-reported outcomes (PROs). RWE is used in a variety of healthcare settings to support decision-making, product evaluation, and research beyond the boundaries of traditional trials.
Defining Real World Evidence
Real world evidence (RWE) refers to clinical insights drawn from data collected during routine care, outside of controlled trial environments. It reflects how treatments, devices, and care strategies are used across different settings and patient populations.
RWE may be used to evaluate clinical practices, inform regulatory submissions, support product development, or guide operational planning. Its flexibility and relevance across healthcare and life sciences make it a valuable complement to traditional research methods.
Key Sources of RWE
RWE is built from data captured during the course of routine care. Common sources include electronic health records (EHRs), insurance claims, clinical registries, and pharmacy systems. These sources often contain information on diagnoses, procedures, medications, and outcomes.
Additional inputs may come from PROs, wearable devices, and administrative data. Together, these datasets provide a broader view of how care is delivered and experienced across different populations and settings.
The Role of Patient-Reported Outcomes (PROs) in the RWE Landscape
PROs offer a direct view into how patients experience their care. These self-reported measures capture information on symptoms, function, and quality of life that may not be visible through clinical data alone.
In the context of RWE, PROs add valuable depth to traditional data sources. When collected consistently and at scale, they help round out the clinical picture and bring the patient’s perspective into analysis, evaluation, and decision-making.
The Role of RWE in Modern Healthcare
RWE is becoming increasingly relevant across healthcare as organizations look for ways to improve care delivery, assess performance, and make informed decisions. Because it reflects what happens in actual practice, RWE can help identify patterns, variations, and opportunities that may not surface in controlled research settings.
Health systems, life sciences companies, and regulatory bodies use RWE in different ways, but the goal is often the same: to better understand how care is delivered and experienced in real-world environments.
RWE in Medical Device Research and Validation
Medical device development benefits from insights into how products perform outside of controlled trials. RWE helps evaluate device use, performance, and outcomes in real-world clinical settings and may be used to support regulatory decision-making for medical devices, as outlined in recent FDA guidance.
By analyzing data from sources such as EHRs and PROs, researchers can observe how devices are used across patient populations and care environments. These insights can inform design improvements, post-market monitoring, and evidence generation for regulatory or commercial purposes.
Regulatory Landscape and Industry Momentum
Regulatory agencies have shown growing interest in RWE as a complement to traditional clinical trial data. In some cases, RWE may be used to support product approvals, label expansions, or post-market surveillance, depending on the type and quality of the data.
At the same time, life sciences companies and healthcare organizations are building infrastructure to generate and use RWE more systematically. This momentum reflects a broader shift toward real-world insights as part of product development, compliance, and value demonstration strategies.
Challenges in RWE Generation and Adoption
While RWE offers flexibility and breadth, generating it at scale comes with practical challenges. Data quality, standardization, and interoperability can vary widely across systems, making consistent analysis more difficult.
Integrating RWE efforts into existing workflows also requires coordination across clinical, technical, and administrative teams. Without the right infrastructure in place, it can be difficult to organize, manage, and apply the data effectively.
How PatientIQ Enables Real World Evidence at Scale
PatientIQ simplifies the process of collecting and analyzing real-world data by providing a platform designed for healthcare workflows. Its cloud-based solution integrates with EHRs, automates data capture, and streamlines how information is organized and accessed.
With built-in analytics, biostatistical tools, and configurable survey workflows, PatientIQ enables healthcare organizations to generate RWE more efficiently. The platform also supports the collection of PROs, offering additional context and visibility into real-world care experiences.
Use Case: Medical Device Validation with PatientIQ
Medical device companies use PatientIQ to capture device-specific outcomes within established standard-of-care pathways. Data collection is embedded into routine clinical workflows, using validated instruments and existing care touchpoints.
Device-related insights are incorporated into standard outcome collection while care delivery remains unchanged. Clinical data and PROs are gathered at intervals already aligned with practice patterns, keeping data generation consistent with everyday care.
This approach allows manufacturers to observe device performance across procedures, patient populations, and care settings while maintaining alignment with real-world clinical practice and regulatory expectations.
The Future of Real World Evidence
Interest in RWE continues to grow across healthcare and life sciences. As data infrastructure improves and workflows become more connected, organizations are finding new ways to use real-world insights across clinical, operational, and regulatory domains.
Technology platforms that streamline data collection and analysis will likely play a larger role in how RWE is produced and applied. With increased attention on outcomes, transparency, and accountability, RWE is positioned to remain a relevant part of how care is evaluated and improved.
