Domain-Specific Large Language Model Assistance for Emergency Neurological Diagnosis and Treatment: A Randomized Controlled Clinical Trial
This study will evaluate whether Xuanwu-NeuroAid 2.0, a large language model for emergency neurology, can improve 30-day diagnostic quality in adults with acute neurological symptoms.
Physicians will be randomly assigned to AI-assisted care or usual care.
In the AI-assisted group, the model will provide diagnostic and management suggestions, while physicians will make all final clinical decisions.
The usual-care group will receive standard emergency neurology care without large language model assistance.

详细说明
This multicenter, prospective, cluster randomized trial will evaluate whether Xuanwu-NeuroAid 2.0, a domain-specific large language model for emergency neurology, can improve diagnostic quality in adults presenting with acute neurological symptoms.
Physicians will be randomized to AI-assisted care or usual care.
In the AI-assisted group, the model will provide diagnostic and management suggestions based on available clinical information, while physicians will remain responsible for all final clinical decisions.
the model's recommendations could be disregarded when they were considered inappropriate.
The usual-care group will receive standard emergency neurology care without large language model assistance.

干预/治疗 |
|---|---|
|
实验性的：AI-assisted group
Physicians in this group will use Xuanwu-NeuroAid 2.0 during emergency evaluation and management.
|
Xuanwu-NeuroAid 2.0 is a large language model used to support emergency neurology evaluation and management.
It generates diagnostic and management suggestions based on available clinical information, including history, physical examination, laboratory results, and imaging data.
Physicians may interact with the model multiple times, but remain responsible for all final clinical decisions.
Its recommendations may be overridden when considered inappropriate.

|
无干预：Usual-care group
Physicians in this group will provide standard emergency neurology care without large language model assistance.

措施说明 |
大体时间 |
|---|---|---|
|
Diagnostic-care quality risk
大体时间：Day 30
|
A composite outcome defined as the occurrence of any of the following: a diagnostic discrepancy within 30 days; unplanned medical care within 30 days; harms related to the index emergency care within 30 days; or all-cause death within 30 days.
|
Day 30

措施说明 |
大体时间 |
|---|---|---|
|
Diagnostic discrepancy
大体时间：Day 30
|
Diagnostic discrepancy is defined as disagreement between the emergency department final diagnosis and the 30-day expert-adjudicated reference diagnosis.
|
Day 30
|
|
Quality of diagnostic testing and management recommendations
大体时间：Day 30
|
The quality of diagnostic testing and management recommendations made during the index emergency department encounter will be assessed by blinded expert adjudicators after completion of 30-day follow-up, using a 5-point Likert scale.
Higher scores indicate higher quality of diagnostic testing and management recommendations.
|
Day 30
|
|
Patient satisfaction with emergency care
大体时间：Immediately after the index emergency department encounter, within 48 hours
|
Patient satisfaction with emergency care will be assessed after the index emergency department encounter using a 5-point Likert scale, ranging from 1 to 5, with higher scores indicating greater satisfaction.
|
Immediately after the index emergency department encounter, within 48 hours
|
|
Time spent per patient encounter
大体时间：Time from start of physician evaluation to completion of final diagnosis and disposition decision, within 48 hours.
|
Time spent per patient encounter is defined as the duration from the start of physician evaluation to completion of the emergency department final diagnosis and disposition decision during the index emergency department encounter.
|
Time from start of physician evaluation to completion of final diagnosis and disposition decision, within 48 hours.
|
|
Clinician-reported workload
大体时间：Immediately after each index emergency department encounter, within 48 hours.
|
Clinician-reported workload will be assessed by the treating physician using a single-item 5-point Likert scale, ranging from 1 to 5. Higher scores indicate greater perceived workload.
|
Immediately after each index emergency department encounter, within 48 hours.
|
|
EQ-5D-5L at 30 days
大体时间：Day 30
|
Health-related quality of life will be assessed using the EuroQol five-dimension five-level questionnaire.
The EQ-5D-5L utility index score will be derived according to the applicable value set.
The maximum score is 1, indicating full health; higher scores indicate better health status.

大体时间：From completion of the index emergency department encounter to Day 30
|
Unplanned medical care is defined as any unscheduled emergency department visit, outpatient visit, or hospital admission within 30 days after the index emergency department encounter.
|
From completion of the index emergency department encounter to Day 30
|
|
Harms related to this emergency care within 30 days
大体时间：From completion of the index emergency department encounter to Day 30
|
Harms are defined as adverse clinical events within 30 days after the index emergency department encounter.
