Surveys (eCOA, ePRO, ClinRO, PerfO)

Collect high quality clinical outcomes (eCOA) from anyone, anywhere.

Electronic clinical outcome assessments (eCOA) are measures of how a participant feels or functions and can be collected through various mechanisms, including surveys, eDiaries, self- and caretaker-reported measurements, symptom trackers, ecological momentary assessments, and more.

eCOA provide a decentralized and more flexible method to collect participant data for digital clinical trials and research.

There are four major types of electronic outcomes:

  1. Participant-reported outcomes (PROs) – data reported directly by a participant without interpretation by a clinician or trained healthcare professional
  2. Clinician-reported outcomes (clinROs) – data reported by a clinician or trained healthcare professional, often involving an interpretation of the participant’s observable behaviors or measurements
  3. Performance outcomes (PerfOs) – measurement based on a standardized task
  4. Observer-reported outcomes (ObsROs) – data reported by an observer (e.g., parent or guardian)

eCOA confer a number of benefits on clinical trials and research compared to traditional methods of collecting clinical outcome assessments.

More accurate
and reliable

Data is collected directly from the source, requiring no source data verification. Electronic collection of clinical outcomes at flexible times also adds temporal context to the data and is less reliant on participant recall.

Part of daily

eCOA can be collected anywhere through a participant’s personal device. Participation does not require access to a healthcare provider, allowing for the expansion of the potential target population.

Improve participant experience

Individuals are not required to travel to a healthcare provider to be an active participant. eCOA can also be completed at the patient’s own pace and when it is most convenient for them.

Use Case: Providing Mental Health Precision Treatment (PROMPT) Study

The University of Michigan PROviding Mental health Precision Treatment (PROMPT) study uses the MyDataHelps™ digital clinical trial and research platform to understand patient characteristics that influence incidences of depression and anxiety and to evaluate the impact of new digital treatments on mental health. To this end, PROMPT collects eCOA through surveys (PHQ9, GAD7) at baseline, 6 weeks, 18 weeks and 12 months. In addition, participants complete a daily mood survey. eCOA collection for PROMPT with the MyDataHelps™ platform shows impressive compliance rates—daily mood score surveys are completed at 82.6% on average, 92% of participants have submitted their 6-week surveys, and 81% have provided their 18-week surveys.
