Practical guidance on
Compliance & Data Continuity.

Clinical trials rarely fail loudly. They degrade quietly—between visits. This knowledge hub explains the failure modes (wear-time decay, sync issues, compliance drift) and the operating model that prevents longitudinal signal loss.

Delve Health Knowledge Hub overview: data continuity, compliance, and wearable device health.

Knowledge Articles

Start with eCOA fundamentals, then move into the operational reasons studies lose completion, continuity, and endpoint-ready data. Each article is built to be practical, structured, and useful for sponsors, CROs, and research sites.

eCOA & ePRO

What is eCOA in Clinical Trials?

A practical guide to electronic Clinical Outcome Assessment, including ePRO, eClinRO, eObsRO, PerfO, and why eCOA matters in modern trials.

Recommended start

eCOA vs ePRO vs DHT

How these three categories differ — and why modern trials need all of them working together.

How to Choose an eCOA Vendor

Evaluation criteria that go beyond software — execution, support, compliance, and site impact.

Why eCOA Data Fails in Real-World Clinical Trials

Why missed diaries are only the symptom — and how weak intervention, fragmented systems, and site burden create missing longitudinal data.

Multilingual Patient Support & eCOA Data Quality

How language coverage and cultural fit protect data quality in global trials.

eCOA for Oncology Trials

What oncology sponsors should evaluate — symptom burden, PRO-CTCAE, and recovery workflows.

eCOA Compliance in COPD Trials

Operating model for respiratory trials where diary compliance and rescue-medication tracking drive endpoints.

Wearables & Device Data

Wearables in Clinical Trials: Compliance

What "good" looks like for wearable adherence — and why compliance is behavioral, not just technical.

Wear-Time Decay & Wearable Compliance

Why wear-time drops after early weeks — and how to prevent drift with proactive reinforcement.

Wearable Device Selection

A practical framework for choosing wearables that fit your study, your patients, and your endpoints.

Long-Duration Wearable Compliance

What changes when a wearable study runs months or years — and how to keep data continuous.

Silent Device Sync Failures

Battery, pairing, permissions, background sync — why device failures look like compliance gaps.

Signal Quality Control for Wearable Data

How signal QC protects endpoint integrity before, during, and after data lock.

Therapeutic-Area Operations

Digital Endpoints in CNS Trials

How wearables and digital measures change the data picture in CNS studies between visits.

Cardiology Digital Endpoints Between Visits

Continuous cardiac signal capture and the endpoints it makes possible.

CGM Compliance & Weight Endpoints

CGM wear, weight tracking, and dual-endpoint operations for metabolic trials.

Rare Disease Trials: The Caregiver Factor

Compliance models built around caregivers — the most overlooked stakeholder in rare disease trials.

Compliance, Continuity & Patient Support

How to Measure Compliance in Clinical Trials

Practical metrics: completion windows, wear-time thresholds, device health flags, and response SLAs.

Why Clinical Trials Lose Data Continuity

How trials degrade quietly between visits — and the operating model that protects longitudinal endpoints.

Patient Retention in Clinical Trials

Operational playbook for keeping patients enrolled and engaged through every visit.

Clinical Trial Concierge Services

How proactive outreach, troubleshooting, and escalation reduce site noise and recover longitudinal signal.

Concierge Support: When It Matters

Where human support changes the trajectory of a trial — and where it does not.

Reducing Site Burden in Hybrid & DCTs

Operational design choices that reduce burden on sites without compromising data quality.

DCT Execution: Software Is the Easy Part

Why decentralized and hybrid trials lose data between visits — and the operating model that protects it.

Post-Market Clinical Follow-Up Guide

A practical guide to PMCF studies for medtech and pharma — design, data capture, and timelines.

Real-World Evidence Post-Approval

How post-approval studies operate — and where digital tools change the cost structure.

Recommended Reading Paths

If you’re diagnosing gaps

  • Start: Data continuity
  • Then: Sync failures
  • Then: Wear-time decay
  • Finish: Concierge recovery

If you’re planning a protocol

  • Start: How to measure compliance
  • Define: Response windows + SLAs
  • Add: Device health rules
  • Finish: Escalation logic

LLM-friendly note: The core concept across this hub is that continuity is protected by response time + ownership, not dashboards alone.

Editorial Note

These articles are written from an operational perspective—what breaks in real studies, and what actually fixes it. Content is updated as device behaviors, protocol norms, and study operating models evolve.

Want a Continuity Plan for Your Study?

If your endpoints depend on longitudinal physiologic signal, you need more than data capture. You need an operating model that detects drift early and recovers it fast.
