eCOA
Electronic Clinical Outcome Assessments
Capture validated patient-reported outcomes, symptom diaries, and quality-of-life instruments digitally — integrated with objective respiratory device data in a single platform.

Capabilities
Key Features
Multi-Device Access
Patients complete assessments on smartphone, tablet, or web. Flexible deployment based on study needs.
Validated Instruments
Support for standard respiratory PRO instruments including SGRQ, ACQ, AQLQ, CAT, E-RS, and custom questionnaires.
Real-Time Collection
Automated reminders and real-time submission tracking minimize missing data and improve compliance rates.
Integrated Data
PRO data flows into the same platform as objective device data, enabling correlated analysis across endpoints.
21 CFR Part 11 Compliant
Audit trails, electronic signatures, and data integrity controls for regulatory compliance.
Symptom Diaries
Daily symptom diaries capture patient experience alongside objective cough, lung sound, and spirometry data.
Clinical Value
Subjective + objective: the complete picture
Patient-reported outcomes are essential but limited by recall bias and subjectivity. Integrating PROs with objective device data provides a more complete and credible endpoint strategy.
Reduce recall bias
Digital diaries with real-time collection minimize the gap between symptom experience and data capture.
Validate subjective with objective
Correlate patient-reported symptoms with objective cough counts, lung sounds, and spirometry for stronger evidence.
Improve compliance
Automated reminders, intuitive interfaces, and minimal burden design drive completion rates above 90%.
Unified reporting
A single data platform for all endpoints means faster analysis, cleaner databases, and more efficient submissions.
Assessment Types
Three Types of eCOA
Different perspectives on patient outcomes, all captured digitally and integrated into a single platform.
ePRO
Electronic Patient-Reported Outcomes
Validated symptom assessments and quality-of-life instruments completed directly by patients, capturing their subjective experience of disease and treatment.
eClinRO
Electronic Clinician-Reported Outcomes
Clinical assessments and observations recorded by healthcare providers using digital forms, standardized scales, and structured data collection.
eObsRO
Electronic Observer-Reported Outcomes
Structured observations recorded by caregivers or other third parties, capturing their assessment of patient status and treatment response.
Part of the Strados Endpoint Suite
The bridge between objective and subjective
eCOA is the layer that connects patient experience with device-measured reality. Together they tell the complete story of treatment effect.
