Participant Flow Monitoring is a critical feature within the DecenTrialz platform that enables Sponsors and CROs to track the movement of potential participants through the pre-screening phase of a clinical trial. This phase includes initial interest, screening question completion, eligibility assessment, and referral readiness, but excludes post-referral or in-clinic activities, which remain under the research site’s purview.
This module is designed to provide transparent, real-time oversight into early participant engagement while ensuring compliance with informed consent, privacy, and ethical standards.
What Is Tracked in Participant Flow Monitoring
The following milestones are tracked for each trial participant during the pre-screen phase:
1. Match Initiation
- Participant has been matched based on condition, location, or demographics
- Timestamp of match initiation recorded
2. Pre-Screener Started
- Participant begins the structured health and demographic questionnaire
- Time taken to complete pre-screener logged for analytics
3. Pre-Screener Completion
- Participant finishes all required questions
- Automatic inclusion/exclusion filtering applied
- Eligibility result (Pass / Ineligible / Needs Review) displayed
4. Referral Readiness
- If eligible, participant is shown next steps (e.g., referral form or study overview)
- Option to opt out is always available
- Consent to be contacted by research site is recorded and stored
5. Consent Audit Trail
- All affirmative responses (e.g., “I agree to be contacted”) are securely timestamped
- No participant is referred without this explicit consent
How Sponsors & CROs Can Use This Feature
This view helps operational teams:
- Analyze participant drop-off points in the pre-screening journey
- Identify if questions are too complex, sensitive, or time-consuming
- Detect potential bias in eligibility results (e.g., certain groups always ineligible)
- Validate if matching logic aligns with actual study requirements
- Monitor geographic or demographic skew in participation
Each data point is anonymized and aggregated unless individual-level review is required by IRB-approved protocol or sponsor request.
Data Visualization & Filtering Options
Participant Flow Monitoring includes:
- Funnel Charts showing step-by-step conversion rates
- Heat Maps for time-to-complete metrics by location
- Completion Time Analytics segmented by age group, gender, or condition (de-identified)
- Drop-Off Reason Tags where users exited before completion
Filters include:
- Study
- Time Period
- Site
- Age Range
- Eligibility Status
- Response Flags (e.g., skipped questions)
All data can be exported for internal review or regulatory documentation.
Regulatory & Ethical Safeguards
- No identifiable information is shown unless de-identified summaries are insufficient and specific IRB provisions exist.
- Every participant interaction is logged with audit-trail compliance (21 CFR Part 11).
- Participants may exit at any point without obligation, and the system ensures this right is always presented clearly.
- Consent for contact or referral is never assumed, it must be explicitly granted and is securely recorded.
Key Note: Early-stage transparency is one of the strongest predictors of trial success. Participant Flow Monitoring enables Sponsors and CROs to identify engagement challenges, improve protocol design, and foster ethical, data-driven outreach. Use these insights to make participant-first improvements that uphold your obligations under ICH-GCP, HIPAA, and IRB standards.
