Real-World Evidence & Phase 4 Trial Coordination

CAREFUL turns protocol visits, patient-reported outcome measures (PROMs), adverse event reports and follow-up assessments into a single tracked plan, with named owners, due dates and a complete audit trail — across every site, every clinician and every patient.

Your EDC records what was measured. CAREFUL coordinates what has to happen, by whom, and when. The two work alongside each other — your EDC continues to do what it does well, and CAREFUL does what EDCs were never designed for.

The problem

Phase 4 trials and real-world evidence studies fail for one main reason: patients are lost to follow-up. Once a patient leaves the controlled environment of a Phase 3 site, they return to normal care — across multiple GPs, hospitals, pharmacies and community services. PROMs go uncollected. Adverse events go unreported. Protocol windows are missed.

Electronic data capture (EDC) systems are designed for trial data entry, not for clinical coordination. Case report forms live in trial databases that day-to-day clinicians do not use. Site coordinators chase patients by phone and email. Sponsors discover compliance gaps months later, when the data is already incomplete.

The cost is enormous. A Phase 4 trial that misses its retention target may need to be repeated, at a cost of tens of millions of dollars and years of delay to regulatory submission and reimbursement.

How CAREFUL coordinates real-world follow-up

CAREFUL gives every enrolled patient a longitudinal coordination plan that follows them across every site and every clinician. Each protocol visit, each PROMs collection point and each follow-up assessment becomes a tracked action with a named owner, a due date and a complete audit trail.

When a patient is seen by their GP between protocol visits, that GP can see the trial plan, record interim observations and flag adverse events directly in CAREFUL — without learning a new EDC system. The site coordinator has real-time visibility of every patient's status and outstanding items, across every site.

Patients can record their own outcomes through the CAREFUL mobile app, on iOS and Android. PROMs become structured actions, completed at the right time, by the right person, against the right protocol — with reminders and a defensible audit trail.

CAREFUL works across organisational boundaries — between trial sites, primary care, community services and the patient themselves. These are exactly the boundaries that real-world evidence collection has to cross.

CAREFUL alongside your EDC

EDCs were the right answer to a real problem. Paper case report forms were illegible, unsearchable and impossible to audit. Digitisation transformed how trial data is captured, queried and locked.

But the EDC is fundamentally a record. It captures what was measured, what was reported, what was observed. It does not coordinate what has to happen next. It does not name who is responsible for the open thread of the protocol. It does not show every site, every clinician and every patient what the others are doing.

The EDC captures

• Validated case report form data
• Lab results and vital signs against protocol windows
• Adverse event narratives once they have been written up
• Audit trail of data entry, queries and locks

The EDC does not capture

• What's happening now, in real time, across every site
• What's happening next, with named owners and due dates
• Who is responsible for each open protocol action
• The conversation around a referral, a query or a missed visit
• Status visible to every clinician caring for the same enrolled patient

This is not a flaw of EDCs. It is a feature of what they were built for. They are records, designed for data capture, query resolution and regulatory submission. The questions of live coordination — now, next, responsibility — were left to the human layer of phone calls, spreadsheets and email chase-ups. That layer no longer scales.

CAREFUL works alongside any EDC. It does not replace the record; it adds the coordination the record was never designed to provide.

Proven at scale, in real-world care

In Melbourne, Dr Henry Konopnicki used CAREFUL to coordinate the care of 100 elderly patients across five separate healthcare organisations for 12 months. Results were presented at the BMJ/IHI International Forum in Brisbane:

• 91% of staff reported improved safety
• 91% reported improved workflows
• 97% of nurses reported better communication with doctors
• 30–60 minutes saved per GP per day

This is not a Phase 4 trial — but it is the same coordination problem. A defined cohort of patients, followed for many months, across every organisation involved in their care, with structured action tracking and a complete audit trail.

Audit, compliance and data integrity

Every action in CAREFUL is recorded with a timestamp, a named owner and a complete audit trail. The platform runs on Microsoft Azure in the appropriate data sovereignty zone, is GDPR-compliant, ICO-registered (ZA249706) and Cyber Essentials Plus certified. It aligns with NHS DSPT and DCB0129 clinical safety standards.

Role-based access controls keep trial data separate from routine clinical data, while still allowing clinicians to see what they need to coordinate care safely.

For sponsors, this means a defensible record of protocol adherence and PROMs collection. For investigators, it means fewer queries and faster database lock. Sponsors should still complete their own validation against 21 CFR Part 11 and EU Annex 11 requirements for use in regulated trials — CAREFUL provides the technical foundations for that validation.
