Unified eCOA
That Patients Finish.

Delve Health combines modern eCOA with real-time QC, wearable data, and human support to keep diaries complete, reduce deviations, and eliminate site troubleshooting burden.

92–98% diary completion · 2–3× retention uplift.

eCOA Built for Real-World Research

Clinical outcomes fail when patients miss diaries, devices break, or sites can’t support troubleshooting. Delve Health solves this by blending modern eCOA, wearable-driven insights, and human engagement into one unified ecosystem.

Data becomes more reliable. Patients stay supported. Sites stay unburdened. Sponsors get cleaner evidence with fewer deviations and faster readouts.

  • Multilingual, global-ready eCOA + ePRO
  • Real-time QC and deviation prevention
  • BYOD or fully provisioned devices with SIM
  • Wearables + ePRO harmonized to create digital endpoints
  • Concierge support in 120+ languages

The Three Pillars of Modern eCOA

High-performing eCOA isn’t just digital forms. It’s the intersection of patient experience,
protocol rigor, and continuous support  designed to work in the real world.

Patient-Centric, Multilingual, Accessible

Mobile-first assessments with adaptive UX, multimedia prompts, and multilingual support.

Digital Measures

Validated, fit-for-purpose measures from wearables and sensors, ready for regulators.

Concierge-as-a-Service™

Human teams who own the work of keeping participants active, informed, and on schedule.

A Flexible, Powerful Form Builder

Build protocol-aligned instruments in minutes — no custom development needed. StudyPal’s authoring tools let research teams design, test, validate, and deploy assessments faster than traditional eCOA vendors.

  • PRO, ClinRO, ObsRO, PerfRO support
  • Full branching, scoring, conditional logic
  • Audio, video, and image capture inside forms
  • Sequential forms and multi-part workflows
  • Visit windows auto-adjusted to patient behavior
  • Real-time edit checks and version control

All forms stay aligned with regulatory expectations — including FDA, EMA, and ICH E6(R3) guidance.

Subjective + Objective Data in One Place

Wearables provide objective data; ePRO captures subjective experience. Delve Health merges the two — enabling richer endpoints, early signal detection, and context around patient behavior.

  • FDA-aligned digital endpoints
  • Activity, HR, HRV, SpO₂, sleep, respiratory data
  • Correlated with symptom diaries, ClinRO, and visit forms
  • Real-time biomarker trends and alerts

This is the future of evidence generation: signals + symptoms → complete insight.

Where Other eCOA Vendors Stop, Humans Take Over

Software alone cannot fix missed diaries, low tech literacy, battery issues, or sync failures. Delve’s Concierge-as-a-Service™ becomes the operational engine behind your study.

  • Follow-up on missed entries in real time
  • Multilingual patient coaching & troubleshooting
  • Direct support for sites during busy visit days
  • Reduced deviations, higher compliance
  • Proactive intervention when wearable or app issues occur

It’s not just eCOA — it’s eCOA with a human safety net.
