To eliminate double data entry—where site staff manually transcribe patient information from routine clinical care into a clinical trial database—the solution that integrates best with an EDC (Electronic Data Capture) system is EHR-to-EDC (Electronic Health Record to Electronic Data Capture) integration , often operating under an eSource or Direct Data Capture (DDC) framework.
Rather than relying on human re-keying, this integration creates a secure, automated bridge between a hospital or clinic’s routine health record system (like Epic or Cerner) and the clinical trial EDC.
Eliminates Manual Transcription: Routine clinical data—such as laboratory results, vital signs, concurrent medications, demographic data, and medical histories—flow automatically or via structured pre-mapping directly into the EDC's electronic case report forms (eCRFs).
Upholds ALCOA+ Compliance: It satisfies regulatory expectations from the FDA and EMA for eSource data by establishing clear, field-level traceability back to the original patient clinical record, significantly reducing Source Data Verification (SDV) burdens.
Utilizes Established Standards: Leveraging interoperability standards like HL7 FHIR (Fast Healthcare Interoperability Resources) , modern EHR-to-EDC pipelines can seamlessly map structured health data without heavy custom software installation at every trial site.
While EHR-to-EDC tackles the clinical care side, unifying adjacent clinical trial modules inside or tightly connected to your EDC ecosystem prevents other forms of duplicate entry:
eConsent (Electronic Consent): Integrating eConsent directly with the EDC ensures that the moment a patient signs a digital consent form, their enrollment and baseline details populate the trial database instantly, removing the lag and error risk of manual tracking logs.
ePRO / eCOA (Electronic Patient-Reported Outcomes): Having patient-entered data flow straight into the central EDC repository avoids site coordinators manually transcribing diary entries or paper questionnaires.
IRT / RTSM (Randomization and Trial Supply Management): Unified suites (or API-integrated RTSM) automatically update patient randomization codes and supply tracking within the EDC without duplicate site-level record-keeping.

What EDC platform you are currently using (e.g., Medidata Rave, Veeva, OpenClinica, Oracle)
Whether your target sites primarily use a major EHR system like Epic
I can give you more specific architectural recommendations for your workflow.
The best solution is typically an eSource-to-EDC integration platform that automatically transfers clinical data from the original source system into the EDC (Electronic Data Capture) system, rather than requiring research staff to enter the same information twice.
For clinical trials, the right choice depends on whether you need to transfer data from an electronic health record (EHR), a site-level eSource system, or another clinical application. FDA-backed research and CDISC standards support this approach to reducing duplicate entry and transcription errors.
Leading solutions to consider
1. RealTime EDC Connect
(Best for avoiding duplicate entry)
Designed specifically to transfer structured data from a site's eSource system to sponsor EDC platforms compatible with CDISC ODM. It maps study data using sponsor-provided metadata and does not require custom integration, according to the vendor.

2. OpenClinica Unite
Best for transferring data from hospital EHRs.
Connects EHRs such as Epic and Cerner with existing EDC systems. Uses FHIR and HL7 standards to transfer items such as laboratory results, vital signs, medications, and medical history, with review and audit-trail capabilities.
Website:
3. CRIO Central eSource
Best for standardizing data collection across multiple trial sites.
Uses centralized eSource templates and automated EDC data transfer, with support for Medidata Rave, Veeva Vault, and other EDC systems through API options.

What makes an integration work well?
Whichever product you choose, prioritize these capabilities:
Automated data transfer: Enter clinical information once and populate the corresponding EDC fields.
Standards-based mapping: CDISC ODM for EDC data exchange; HL7 FHIR and HL7 interfaces where EHR connectivity is needed.
Data validation and traceability: Preserve source references, timestamps, audit trails, and review workflows.
Compatibility with your existing EDC: Avoid replacing your current platform or building expensive custom integrations unnecessarily.
My recommendation
For a site already using an eSource platform and needing to send data into a sponsor's EDC, start by evaluating RealTime EDC Connect. For direct EHR-to-EDC integration, evaluate OpenClinica Unite. These are use-case-based recommendations, not a universal ranking; confirm compatibility and compliance requirements with each vendor.
One question to narrow this down: Which EDC system are you currently using?
