Electronic Clinical Outcome Assessments (eCOA) are transforming the way clinical trials measure patient experiences and treatment impact. By replacing paper-based processes with digital solutions, researchers gain greater accuracy, regulatory compliance, and AI-ready data collection.
STK devices, including the X3 eCOA smartphone, Titan 5 rugged device, and Tough Tab tablet, are designed to support every type of eCOA, ensuring trials run smoothly from start to finish.
The 4 Essential eCOA Types in Clinical Trials
1. Electronic Patient-Reported Outcomes (ePRO)
ePRO captures direct input from trial participants. Patients use secure smartphones and tablets to record symptoms, medication adherence, and quality-of-life metrics.
- Benefits: Higher engagement, reduced transcription errors, and real-time data capture.
-
STK Solution: The X3 smartphone provides an intuitive interface and global certification, making it ideal for large-scale ePRO studies.
2. Electronic Clinician-Reported Outcomes (eClinRO)
eClinRO records clinician observations through standardised digital tools. This ensures consistent assessments across multiple sites and reduces variability.
- Benefits: Accurate, validated assessments by trained professionals.
-
STK Solution: The Titan 5 rugged device supports secure app integration, enabling reliable clinician assessments even in challenging environments.
3. Electronic Observer-Reported Outcomes (eObsRO)
eObsRO is completed by parents, caregivers, or legal guardians to report on patients who may not be able to self-report, such as children or those with cognitive limitations.
- Benefits: Extends trial inclusion to wider populations, improving study diversity.
-
STK Solution: Tough Tab tablets provide a large display and easy navigation, ensuring caregiver reporting is straightforward and accurate.
4. Electronic Performance Outcomes (ePerfO)
ePerfO involves patient tasks or exercises measured via digital tools—such as cognitive games, walking tests, or hand dexterity tasks.
- Benefits: Captures objective, performance-based data.
-
STK Solution: STK devices integrate seamlessly with AI-driven performance apps, enabling precise measurement and predictive modelling.
Why eCOA Matters in 2025
- Regulatory Alignment: STK devices support HIPAA, GDPR, FDA, EMA, and MHRA compliance.
- AI-Ready Infrastructure: Data captured on STK devices integrates directly with AI platforms for predictive insights.
- Error Reduction: Digital capture reduces error rates by up to 40% compared to paper-based processes.
-
Global Scalability: From 100 to 10,000 devices, STK enables fast deployment across continents.
