eCOA and ePRO Solutions for Clinical Trials

Collect patient-reported outcomes and clinical outcome assessments through flexible, mobile-friendly workflows. TrialKit brings eCOA and ePRO together with electronic data capture, configurable eDiaries, participant reminders, and AI-assisted study configuration through Floyd, all within one unified eClinical platform.

Make Clinical Outcome Data Collection Easier for Participants and Study Teams

Collecting clinical outcome data requires an approach that fits both the study protocol and the people participating in it. Assessments must be completed at the appropriate times, data must remain accessible to authorized study personnel, and participants need a straightforward way to report their experiences.

TrialKit supports electronic clinical outcome assessments (eCOA), including electronic patient-reported outcomes (ePRO), through configurable forms, native mobile applications, and web-based access. Participants can complete assigned assessments remotely or during site visits, while research teams manage schedules, monitor completion, and review collected data.

As part of TrialKit’s unified eClinical platform, eCOA and ePRO data can be managed alongside other clinical study information, reducing the need for separate systems and disconnected data collection workflows.

  2. Participant

    Receive Timely Notifications

    Automated notifications help participants know when assessments are available and when completion windows are approaching. Study teams can configure reminder schedules according to protocol requirements.

  3. Site & Study Team

    Monitor Participation and Follow Up

    Sites and study teams can use diary schedules and compliance reports to review assessment completion, identify missed entries, and determine when follow-up may be needed.

Configure eCOA and ePRO Workflows With Floyd

Floyd, TrialKit’s embedded AI model, helps clinical research teams translate protocol requirements into configured study components, including electronic assessments and eDiary schedules.

By assisting with study setup, testing, and analysis, Floyd can reduce repetitive configuration work while giving researchers greater flexibility to evaluate their data collection workflows.

Build Assessments From Protocol Requirements

Use Floyd to interpret protocols and assist with generating forms, visit schedules, edit checks, and conditional logic. Study teams can review and refine the resulting configurations to meet their specific requirements.

Test Data Collection Workflows

Generate synthetic participant data to evaluate configured forms, test assessment scenarios, and identify potential issues before live data collection begins.

Explore Collected Study Data

Use Floyd to ask questions about study data and reports, examine results, and investigate patterns that may warrant further review.

Floyd supports the work of study builders, data managers, and clinical teams while keeping human review, validation, and decision-making central to the process.

Clinical Outcome Data in One Unified eClinical Platform

Clinical outcome assessments are often one component of a broader clinical research program. Managing them alongside other study data can simplify technology oversight and help teams work within a more consistent environment. TrialKit brings eCOA and ePRO together with complementary capabilities across the study lifecycle.

    FAQs About eCOA and ePRO

    What is eCOA in clinical trials?

    Electronic clinical outcome assessment (eCOA) refers to the electronic collection of clinical outcome assessment data. eCOA can include patient-reported outcomes (ePRO), clinician-reported outcomes (ClinRO), observer-reported outcomes (ObsRO), and performance outcomes (PerfO), depending on the assessment instrument and study requirements. For a more detailed explanation, read our guide to what eCOA is in clinical trials.

    What is the difference between eCOA and ePRO?

    eCOA is the broader category of electronically collected clinical outcome assessments, while ePRO specifically refers to outcomes reported directly by patients without interpretation by clinicians or other individuals. For example, a participant completing an electronic symptom diary is providing ePRO data, which is one type of eCOA.

    Does TrialKit support bring-your-own-device (BYOD) studies?

    Yes. TrialKit supports BYOD workflows that allow participants to complete assigned assessments using their own compatible devices. Study-provided devices can also be used when appropriate. Device selection and validation should account for the assessment instrument, study population, and protocol requirements.

    Can TrialKit send automated ePRO reminders?

    Yes. TrialKit supports configurable notifications for scheduled ePRO and eDiary assessments. Study teams can define reminder timing and completion windows to align with the protocol and participant schedules.

    Can ePRO assessments be triggered by participant responses?

    TrialKit supports event-triggered assessment schedules and conditional workflows. Depending on the study configuration, defined events or responses can initiate additional assessments or follow-up data collection activities.

    How can study teams monitor ePRO completion?

    TrialKit provides diary scheduling and compliance reports that show expected, completed, and missed assessments. Authorized study personnel can review participation at the participant, site, or study level.

    Can TrialKit support eCOA in decentralized clinical trials?

    Yes. TrialKit supports remote participant assessments through mobile and web-based data collection, along with related capabilities for eConsent, virtual visits, and wearable data collection. These features can support decentralized and hybrid clinical trial workflows.

    How does Floyd support eCOA and ePRO study configuration?

    Floyd can assist with generating forms, visit schedules, and eDiary configurations from protocol requirements. It can also support synthetic data generation for testing and analysis of collected study data, complementing TrialKit’s existing configuration and validation tools.

    What should sponsors consider when implementing eCOA?

    Important considerations include selecting appropriate assessment instruments, device compatibility, participant accessibility, scheduling and reminder requirements, instrument validation, data integrity, and regulatory expectations. TrialKit provides configurable technology to support eCOA implementation, while sponsors and study teams remain responsible for establishing appropriate study procedures and assessment requirements.
