Grant Period:
July 1, 2023 – May 31, 2028
Goals/Purpose:
This project will rigorously evaluate clinical use, diagnostic and triage accuracy, and effect on patients' care-seeking decisions of a leading symptom checker in emergency and urgent primary care settings. It will also utilize three unique data sets including patients with transient ischemic attacks (TIAs) and strokes to evaluate the effects of patient characteristics on stroke diagnosis by symptom checkers and create new diagnostic and triage algorithms.
Specific Aims:
- Evaluate the diagnosis and triage accuracy, usability, safety and effect on patient decision making of the Ada symptom checker in emergency or urgent care.
- Study the diagnosis and triage accuracy of existing algorithms and create new algorithms with datasets from patients presenting with possible TIA or stroke, including evaluating the effect of patient demographic characteristics.
