Effects of Expert Arbitration on Clinical Outcomes When Disputes Over Diagnosis Arise Between Physicians and Their Artificial Intelligence Counterparts: a Randomized, Multicenter Trial in Pediatric Outpatients
July 4, 2019 updated by: Huiying Liang, Guangzhou Women and Children's Medical Center
We have recently developed an artificial intelligence (AI) framework to diagnose common pediatric diseases.
This randomized controlled clinical trial aims to investigate the effects of expert arbitration on clinical outcomes in the situation where the AI-based diagnosis differs from the diagnosis made by pediatricians.
Study Overview

Unknown
Detailed Description
Based on the historical clinical data of more than 1 million pediatric outpatients in the Guangzhou Women and Children's Medical Center, an AI diagnostic framework has recently been developed for common pediatric diseases [Liang H et al. evaluation and accurate diagnosis of pediatric disease using artificial intelligence.
Nat Med.
2019;25(3):433-8].
This AI framework utilizes predefined schema to extract informative clinical data from free text and reaches clinical diagnoses by hypothetico-deductive reasoning.
In internal validation, the AI system showed accuracy rates ranging from 0.85 for gastrointestinal disease to 0.98 for neuropsychiatric disorders, suggesting that it might be a promising assisting diagnostic tool in clinical practice.
However, there is a lack of evidence-based strategy on how to handle the scenarios where the AI-based diagnosis and the diagnosis made by pediatricians are discordant.
It is legitimate to assume that diseases with discordant diagnoses present more similar clinical features; in this case it is necessary to introduce an extra arbitrator for differential and decisive diagnosis.
Therefore, we conduct this randomized controlled trial to: 1) compare the accuracy of the two diagnostic modes in a real-world clinical setting where the AI-based diagnosis and the diagnosis made by pediatricians are discordant by introducing an expert arbitrator; and 2) look further into the change of clinical outcomes (hospital revisit and hospitalization in the next 3 months after initial visit; average total outpatient cost) due to introduction of the expert arbitrator.
Please note that although the aforementioned AI framework was designed for diagnosis of a wide range of diseases, this clinical trial is limited to outpatients encountered in three specialty clinics, i.e. respirology, gastroenterology, and genito-urology.
The reason for this selection is that the discordant diagnoses are assumed to be more common for these two specialties according to the internal validation result.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Experimental Arm
Each participant receives two diagnoses: one from the AI diagnostic system and the other from pediatricians, and the two diagnoses are discordant.
Participants in the experimental arm will be referred to an expert arbitrator for differential and decisive diagnosis and will receive treatment prescribed by the expert arbitrator.
