  • ObsRO: completed by a caregiver.
  • ClinRO: completed by site staff during the visit.
  • PerfO: performance tests such as a chair rise test, built as site forms.

Something not covered here? Ask us directly.

What is eCOA?

Electronic clinical outcome assessment: collecting patient-reported, observer-reported, clinician-reported and performance outcomes electronically instead of on paper.

What is the difference between ePRO and eCOA?

ePRO covers only what patients report themselves. eCOA also includes caregiver observations, clinician ratings and performance tests.

Can caregivers report?

Yes. Assessments can be set to be completed by a caregiver or proxy.

Which devices are supported?

Phones, home tablets and clinic devices in the browser, plus paper forms entered by site staff where your protocol needs them.

Are validated instruments available?

PROMIS short forms are in the library with licence tracking, and you can build or import other instruments.

Does it need an app?

No. Everything runs in the browser.
