An accurate medical diagnosis depends on the doctor getting a complete picture of the patient's health story, but clinic visits are short. Before some cardiology appointments, patients may be able to speak with an artificial intelligence (AI) "interviewer" - through a secure web page, usually at home - about their symptoms, medications, allergies, medical history, and what they want their doctor to understand. The AI interviewer creates a written summary for the cardiologist. It does not make diagnoses, give treatment advice, or replace the doctor: the cardiologist still takes and verifies the medical history in the usual way, and nothing written by the AI goes into the medical record without the doctor's review. In this study, 60 adults attending a first or new cardiology consultation at London Health Sciences Centre University Hospital or the London Cardiac Institute will be invited to use the AI interviewer before their appointment. Patients who prefer not to take part receive usual care. We will measure how many participants complete the interview and have a summary ready before their visit, how long the interview and the visit take, whether patients find the interviewer easy to use and feel able to explain their concerns, whether cardiologists find the summaries useful and accurate, and whether any important errors or omissions occur. Every summary is checked by the treating cardiologist, and independent physicians review all concerning cases plus a random sample. Results will show whether this workflow is feasible and safe enough to justify a larger study.

Participants coming into LHSC for first cardiology consultation.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Participants will complete an AI Interview prior to cardiology consultation used for history taking, symptom reporting and medication records prior to meeting with the physician.
Usability
Successful completion is defined as completion of the AI interview with a readable, clinically reviewable summary generated and accessible to the treating clinician before the clinician begins the consultation. A summary is usable if not blank, corrupted, or rendered unusable by technical failure; it need not be clinically perfect. Completion may occur at home or through rescue; availability is defined independently of whether the clinician opened the summary (the attestation captures actual use). The primary analysis includes all consented participants whose eligible in-person appointment proceeds and who have an opportunity to receive the study intervention. Failure to receive, initiate, or complete the interview - including technical failure or participant refusal after consent - is counted as unsuccessful completion.
Time frame: Baseline
1) Patient engagement with the chatbot
Measured by the Conversation-Turns Per Session, a validated metric defined as the total number of alternating input-output pairs during the interaction and used as a proxy for depth and fluidity of patient-chatbot interaction \[11\]. For context, CPS values typically range from 1-3 in digital assistants (such as Siri), around 9 in human dialogue, and ≥23 in advanced social chatbots such as Microsoft's Xiaolce \[25\].
Time frame: Baseline
Objective durations
Interview duration (platform); physician-encounter duration (room-entry to room-exit, where recorded); scheduled slot length as context; summarized overall and by setting.
