ePRO for patient-reported outcome studies: PRO and eCOA in one platform with EDC, 21 CFR Part 11–aligned controls, and one audit trail.

Capture’s ePRO module is built into the same platform as EDC and eConsent, so study teams configure PRO instruments alongside their CRFs and consent forms. The configuration process uses the browser-based study builder: you create questionnaires by selecting from supported question types (text, number, scale, slider, single choice, multiple choice, dropdown, date, time, textarea), configure skip logic and branching rules, and set up scheduling (daily, weekly, at specific visit windows, or triggered by events). Participants are enrolled in ePRO through a QR code provided at the site or through the consent process. They access questionnaires on their personal mobile devices through a mobile-optimized web interface—there is no app to download. When a scheduled questionnaire becomes available, participants complete it on their device. Responses are captured with timestamps and linked to the participant’s study record in the same database as clinician-entered data. Study teams can monitor completion rates and identify participants who have missed assessments. Because ePRO data and CRF data share the same dataset and audit trail, there is no reconciliation step before analysis. At database lock, the export includes both clinician-assessed and patient-reported data in one structured file.
PRO endpoints come with specific methodological and regulatory considerations that your ePRO system must accommodate. The FDA’s PRO Guidance (2009) and the EMA’s reflection paper on patient-reported outcomes establish expectations for how PRO data should be collected, validated, and analyzed in clinical trials. Key requirements include: use of instruments with documented psychometric properties, consistent administration conditions, timestamped data entry to avoid recall bias, and a clear audit trail from data collection through analysis. Capture supports these requirements through its integrated ePRO approach. Timestamps are captured automatically when participants complete questionnaires, providing the contemporaneous data entry that regulators expect. Questionnaire versioning ensures that any changes to instruments are documented with audit trail records. Skip logic maintains consistent administration by showing only questions relevant to each participant’s responses. And the unified dataset eliminates the provenance questions that arise when PRO data and clinical data come from different systems. For studies using validated instruments (e.g., EQ-5D, EORTC QLQ-C30, PHQ-9, GAD-7), study teams configure the exact item text, response options, and scoring as specified by the instrument developer. For custom instruments developed for a specific study, the flexible question type library supports the full range of response formats commonly used in PRO research.
Many clinical trials use separate vendors for ePRO and EDC. This dual-vendor approach creates several operational challenges: two contracts to negotiate, two systems to validate, two training programs for site staff, two datasets to reconcile before analysis, and two audit trails that must be reviewed during monitoring and inspections. For small studies and lean teams, this overhead can be disproportionate to the study’s scope. Capture eliminates the separate ePRO vendor by integrating patient-reported outcome collection within the same platform as EDC and eConsent. Study teams configure questionnaires alongside CRFs and consent forms in one study builder. Sites learn one system. Validation covers one platform. And at database lock, one export contains all data—clinician-assessed and patient-reported—in one structured dataset with one audit trail. The compliance advantages of this integration are significant. A single validation scope means less documentation and testing effort. A single audit trail means monitors and inspectors review one system rather than two. And a single dataset means no reconciliation discrepancies that need to be explained during regulatory review. For studies where PRO data is a primary endpoint, this simplification strengthens the data integrity narrative that sponsors present to regulators.
Overview
Patient-reported outcome (PRO) studies place the participant at the center of data collection. Whether measuring symptom severity, functional status, treatment satisfaction, or health-related quality of life, PRO studies depend on participants accurately and consistently reporting their experiences through structured questionnaires, diaries, and assessment instruments. The quality and completeness of this participant-reported data directly determines the study’s ability to demonstrate treatment effects and support regulatory or clinical decisions. ePRO (electronic patient-reported outcomes) replaces paper-based PRO collection with digital questionnaires that participants complete on their own devices. This shift offers significant advantages: timestamped entries eliminate the problem of retrospective diary completion ("parking lot syndrome"), skip logic ensures participants only see relevant questions, and real-time data capture provides immediate visibility into completion rates and data quality. Regulatory agencies including the FDA have issued guidance supporting ePRO as equivalent or superior to paper-based PRO collection when implemented with appropriate controls. Your ePRO system must support diverse question types (scales, sliders, multiple choice, free text, date/time), scheduling logic (daily, weekly, event-triggered), skip logic and branching, and full auditability—all within the same platform as your EDC and consent. Using a separate ePRO vendor creates data silos, reconciliation burden, and audit trail gaps that complicate monitoring and regulatory review. Capture provides ePRO as an integrated module within the same platform as EDC and eConsent. Questionnaires are configured through the browser using 10+ supported question types, with skip logic and branching. Participants enroll via QR code and complete assessments on their own mobile devices. Responses flow directly into the same dataset as clinician-entered CRF data, with the same 21 CFR Part 11–aligned controls and audit trail. This integration eliminates the need for a separate ePRO vendor and ensures that all study data—clinician-assessed and patient-reported—is captured, managed, and exported from one system.
PRO data is only valuable when it is collected consistently, attributed correctly, and managed with the same data integrity controls as the rest of the study. Standalone ePRO systems often operate as separate silos—participants complete questionnaires in one system while clinicians enter CRF data in another, and the two datasets must be reconciled before analysis. This reconciliation introduces opportunities for errors, delays, and audit trail gaps that can be problematic during regulatory review. The integration challenge is particularly acute for studies where PRO data is a primary endpoint. If the ePRO data and the CRF data are in separate systems with separate audit trails, regulatory reviewers must evaluate two independent data governance frameworks rather than one. Any discrepancy between the systems—a participant who appears in one but not the other, timestamps that do not align, data that was modified in one system but not reflected in the other—creates questions about data integrity that the sponsor must resolve. Capture solves this by integrating ePRO within the same platform as EDC and eConsent. When a participant completes a questionnaire on their device, the response is captured with the same audit trail, access controls, and data governance as a clinician-entered CRF field. There is one dataset, one audit trail, and one system to validate. This integration simplifies monitoring, analysis, and regulatory review while reducing the operational burden on study teams. Capture’s ePRO supports 10+ question types including visual analog scales, Likert scales, numeric rating scales, single and multiple choice, dropdown, date/time, and free text. Skip logic and branching ensure participants see only the questions relevant to their responses. Questionnaires can be scheduled daily, weekly, at custom intervals, or triggered by events.
