Heart Failure

Keywords

Artificial intelligence; Speech-to-text; Patient-reported data; Digital health; Patient self-care

Outcome Measures

Primary Outcomes (1)

• Accuracy of AI Voice Assistant Compared With Expert Extraction

  Agreement between AI-generated summaries and expert-reviewed responses (study staff extraction of participants' responses from audio recordings). The responses will be scored on a numerical scale, ranging from 0-17 points with higher points representing greater accuracy of the AI-generated summaries compared to expert-reviewed responses.

  ~3 months

Secondary Outcomes (4)

• Usability of AI Voice Assistant

  ~3 months

• Agreement between AI Voice Assistant Compared With Patient Self-Reported Written Responses

  ~3 months

• Kansas City Cardiomyopathy Questionnaire Scores

  ~3 months

• Qualitative Feedback

Study Arms (1)

AI Voice Assistant

EXPERIMENTAL

Participants in the AI Voice Assistant arm will complete two activities: (1) an interaction with the AI Voice Assistant tool and (2) Paper survey that includes the same questions asked by AI voice assistant. Half of the participants will use the AI Voice Assistant first, while the other half will begin with the paper survey.

Other: Artificial intelligence speech-to-text tool
