Healthcare: Symptom Checker & Triage System
Design a clinically reliable, real-time symptom checker and triage system that combines conversational AI, medical imaging analysis, and patient context modeling to make high-stakes care recommendations under uncertainty, with accuracy and safety guarantees comparable to trained clinicians. The system must reason over incomplete, ambiguous, and sometimes misleading patient inputs; analyze user-submitted images (e.g., skin lesions, wounds, swelling) with calibrated confidence; detect red-flag conditions and escalation risks; adapt triage decisions based on patient history, comorbidities, and medication use without full records; operate within strict medical safety constraints; provide transparent explanations and confidence scores for every recommendation; support multilingual and low-health-literacy users; and be robust against hallucinations, bias, and over- or under-triage, while demonstrably reducing unnecessary ER visits without increasing adverse outcomes.
