77.7–78.9% PC for recent LLMs vs. 70.1% for R4 (P < 0.008)

Recent vision-enabled multimodal large language models (LLMs) significantly outperformed fourth-year residents (R4) on the pediatric in-training examination questions, demonstrating superior accuracy across the board.

>0.98 Intraclass Correlation Coefficient (ICC)

The study observed excellent repeatability of outputs from most LLMs, with an intraclass correlation coefficient exceeding 0.98, indicating consistent performance across multiple trials.

Enterprise Process Flow

12 ITEs (2016-2023) identified
Excluded for prompt optimization/lost answer sheets (10 ITEs remaining)
48 duplicated items removed (498 unique questions)
Korean/English terminology; 22% included medical images
Original examination sheets used without modification

The study meticulously prepared a dataset of 498 unique pediatric in-training examination questions, ensuring the integrity and representativeness of the original examination format.

Performance Disparity: Text vs. Image Questions

Category Recent LLMs (PC) R4 (PC) Key Finding
Overall Questions 77.7-78.9% 70.1% Recent LLMs significantly outperformed R4.
Text-Only Questions 80.1-81.0% 69.6% Recent LLMs showed superior PC compared to R4.
Image-Included Questions <73.9% Comparable to R4 None of the LLMs surpassed R4 performance; both prior and recent models exhibited inferior PC on image-included items than text-only questions.

While recent LLMs excelled on text-only questions, their performance on image-included questions remained comparable to or even inferior to senior residents, highlighting a crucial area for improvement in visual reasoning.

Educational Utility and Future Potential of LLMs

Scenario: The high accuracy of LLMs on ITEs suggests significant educational utility. As adjunctive study tools, LLMs can provide trainees with rapid feedback, exposure to diverse clinical scenarios, and opportunities to practice critical appraisal of AI-generated answers.

Challenge: However, these results are not proof of readiness for autonomous pediatric Clinical Decision Support Systems (CDSS). Further validation on real-world cases and external validation are required.

Outcome: LLMs offer a strong potential to complement traditional pediatric education, fostering improved learning outcomes and critical thinking skills in trainees, but their role remains assistive for now.

73.9% Recent LLMs PC on image-included questions (vs. 80.4% on text-only)

Despite advancements, recent multimodal LLMs achieved significantly lower proportion correct on image-included questions (73.9%) compared to text-only questions (80.4%), highlighting a persistent limitation in visual reasoning for pediatric contexts.
