NCT07432893

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Clinical Quality of Consultation (Clinical Management and Clinical Reasoning Score)

    This outcome assesses the quality of clinical care by comparing AI-assisted, nurse-led consultations with standard physician-led consultations. For patients with hypertension or diabetes mellitus, clinical quality is measured using a clinical management rubric with a raw score range of -2 to 7, assessing data review, complication screening, medication adherence, counseling, and treatment planning, with penalties for inappropriate counseling or treatment. For patients presenting with fever, breathlessness, or musculoskeletal pain, clinical quality is measured using a clinical reasoning rubric with a raw score range of -5 to 10, assessing differential diagnoses, final diagnosis, and next steps, with negative scores for harmful recommendations. Consultations are audio recorded, de-identified, and scored by blinded physicians. Higher scores indicate better alignment with evidence-based, context-appropriate care.

    Day 1 (same study visit, immediately after completion of both consultations)

Secondary Outcomes (2)

  • Patient Experience Score on Exit Survey (Likert Scale Composite Score)

    Day 1 (immediately after completion of the nurse + LLM consultation during the study visit)

  • Nurse-Reported Acceptability and Feasibility Themes from Semi-Structured Interviews

    Through study completion (after nurses complete a minimum of 10 AI-assisted consultations; up to 9 months)

Study Arms (2)

Nurse+Large language model clinical consultation

EXPERIMENTAL

Participants in this arm receive a nurse-led primary care consultation supported by a large language model (LLM)-based clinical decision support tool. During the consultation, a trained nurse conducts routine history taking and clinical assessment and engages in a multi-turn interaction with the LLM via a digital interface to support differential diagnosis, clinical reasoning, and evidence-based treatment and follow-up planning. The nurse may ask additional questions of the patient based on LLM prompts. The final clinical recommendations are generated collaboratively by the nurse using the LLM outputs and documented as a treatment plan. This arm evaluates whether AI-assisted nurse-led care can deliver clinical quality comparable to standard physician-led care in primary health settings.

Other: AI-enabled clinical decision support tool (software) used by nurses

Physician led clinical consultation (standard of care)

ACTIVE COMPARATOR

The doctor consultation represents standard-of-care clinical management that is already known and accepted to be effective for diagnosing and treating the study conditions. It is an active clinical intervention, not a placebo, sham, or no-intervention arm, and it serves as the comparator against the experimental nurse + LLM intervention.

Other: Physician consultation

Interventions

A nurse-led primary care consultation supported by a large language model-based clinical decision support tool. The nurse uses the AI tool during the patient encounter to support clinical reasoning, differential diagnosis, and evidence-based treatment and follow-up planning.

Nurse+Large language model clinical consultation

Participants receive a routine physician-led primary care consultation conducted according to existing clinical practice. The physician independently performs history taking, clinical assessment, diagnosis, and treatment planning without use of the AI tool.

Physician led clinical consultation (standard of care)

Intervention Model
CROSSOVER
Model Details: This study uses a randomized, within-participant crossover interventional design. Each enrolled patient participates in two sequential clinical consultations during a single visit: (1) an AI-assisted, nurse-led consultation (intervention) and (2) a standard physician-led consultation (control). The order of consultations is randomized to minimize order effects. Both consultations address the same clinical condition or symptom and result in independent treatment plans. Because each participant serves as their own control, this design reduces between-subject variability and improves statistical efficiency. Clinical interactions are audio recorded and de-identified, and resulting treatment plans are independently scored by blinded physicians using standardized rubrics to assess clinical reasoning and management quality. In addition, patient experience is assessed via a post-consultation exit survey, and nurse experiences are explored through qualitative interviews.

Data Sharing

IPD Sharing
Will not share

This study involves audio-recorded clinical consultations, detailed transcripts, and qualitative interviews collected in small, identifiable clinic populations. Even after de-identification, there is a meaningful risk of re-identification, particularly from narrative data and voice-derived content. In addition, participant consent forms and ethics approvals are designed for aggregate reporting only, not public IPD sharing.
