The goal of this clinical trial is to learn whether AI-enabled, nurse-led treatment planning can improve the quality of clinical reasoning and management compared with standard physician-led care in adult primary care patients (≥18 years) presenting with hypertension, diabetes mellitus, fever, breathlessness, or musculoskeletal pain in rural and semi-urban India.
The main questions it aims to answer are:
* Does a nurse + large language model (LLM) consultation achieve non-inferior clinical quality scores compared with a standard doctor consultation?
* Is AI-assisted nurse-led care acceptable and satisfactory to patients in primary healthcare settings? Researchers will compare nurse + LLM-led consultations with physician-led standard-of-care consultations within the same participant to see if the AI-enabled nurse model delivers comparable or improved clinical reasoning and treatment planning.
Participants will:
* Receive two sequential consultations for the same visit (one with a nurse using an AI tool and one with a physician, order randomized).
* Have both consultations audio recorded for blinded clinical quality assessment.
* Complete a brief exit survey on communication, trust, and satisfaction after the AI-assisted nurse consultation.
