AI tool to detect fatigue and depression in cardiology patients

Efficacy of a Novel Web-based Fatigue and Cognitive Assessment Platform in Detecting Fatigue and Depression

Indiana University · NCT07218263

This project tests whether the Okaya AI platform can detect fatigue and depression from a short conversational check-in for adults seen in cardiology clinics, compared with PHQ-9 and FAS questionnaires.

What this trial studies

This observational study compares a browser-based AI platform called Okaya to standard questionnaires for fatigue and depression in cardiology patients. During a single baseline visit, the platform records a short conversational check-in and uses computer vision and natural language processing to extract facial and vocal features such as eye contact, facial affect, pitch, volume, and speech patterns. Those features are processed through regression models to produce a composite AI score, which will be compared to PHQ-9 and Fatigue Assessment Scale scores. No interventions are provided and participants complete only the AI check-in and the standard questionnaires.

Who should consider this trial

Good fit: Adults aged 18 or older who speak English, can consent, and are receiving cardiology care are the intended participants.

Not a fit: People who are nonverbal, have significant cognitive disability, active substance use, active suicidal or homicidal ideation, or who do not speak English are unlikely to benefit from this platform or be eligible to participate.

Why it matters

Potential benefit: If successful, the platform could offer a quick, noninvasive way to flag fatigue and depression during cardiology visits so clinicians can follow up appropriately.

How similar studies have performed: Prior research using facial and vocal biomarkers to detect depression has shown promising but mixed results, so this approach is partly supported but not yet established in routine care.
