📚 Background
The integration of Large Language Models (LLMs) into medical diagnostics has been a topic of growing interest. While these models show promise, their performance can vary significantly based on the prompting techniques employed. Traditional methods often lack the structured approach that is essential for effective clinical reasoning, leading to inconsistencies in diagnostic accuracy.
🗒️ Study
This study aimed to evaluate whether a structured clinical reasoning prompt could enhance the diagnostic capabilities of LLMs. Researchers utilized a dataset of 322 quiz questions from Radiology’s Diagnosis Please cases spanning from 1998 to 2023. They compared three prompting approaches: a conventional baseline, a structured two-step approach, and a summary-only method.
📈 Results
The findings revealed that the two-step approach significantly outperformed both the baseline and summary-only methods in terms of diagnostic accuracy. The primary diagnostic accuracy for the two-step approach was 60.6%, compared to 56.5% for the baseline and 56.3% for the summary-only approach. Notably, the accuracy for the top three diagnoses reached 70.5%, 66.5%, and 65.5% respectively, indicating a robust improvement in diagnostic performance.
🌍 Impact and Implications
The implications of this study are significant for the field of medical diagnostics. By adopting a structured clinical reasoning approach, healthcare professionals can leverage LLMs more effectively, potentially leading to improved patient outcomes. This method not only enhances diagnostic accuracy but also aligns with established clinical reasoning processes, suggesting its applicability in real-world clinical settings.
🔮 Conclusion
This study highlights the potential of a structured clinical reasoning prompt to enhance the diagnostic capabilities of LLMs. As healthcare continues to evolve with technology, integrating such methodologies could lead to more accurate and reliable diagnoses. The future of medical diagnostics looks promising with the continued exploration of structured approaches in conjunction with advanced AI technologies.

Structured clinical reasoning prompt enhances LLM’s diagnostic capabilities in diagnosis please quiz cases.
Abstract
PURPOSE: Large Language Models (LLMs) show promise in medical diagnosis, but their performance varies with prompting. Recent studies suggest that modifying prompts may enhance diagnostic capabilities. This study aimed to test whether a prompting approach that aligns with general clinical reasoning methodology-specifically, using a standardized template to first organize clinical information into predefined categories (patient information, history, symptoms, examinations, etc.) before making diagnoses, instead of one-step processing-can enhance the LLM’s medical diagnostic capabilities.
MATERIALS AND METHODS: Three hundred twenty two quiz questions from Radiology’s Diagnosis Please cases (1998-2023) were used. We employed Claude 3.5 Sonnet, a state-of-the-art LLM, to compare three approaches: (1) Baseline: conventional zero-shot chain-of-thought prompt, (2) two-step approach: structured two-step approach: first, the LLM systematically organizes clinical information into two distinct categories (patient history and imaging findings), then separately analyzes this organized information to provide diagnoses, and (3) Summary-only approach: using only the LLM-generated summary for diagnoses.
RESULTS: The two-step approach significantly outperformed the both baseline and summary-only approaches in diagnostic accuracy, as determined by McNemar’s test. Primary diagnostic accuracy was 60.6% for the two-step approach, compared to 56.5% for baseline (p = 0.042) and 56.3% for summary-only (p = 0.035). For the top three diagnoses, accuracy was 70.5, 66.5, and 65.5% respectively (p = 0.005 for baseline, p = 0.008 for summary-only). No significant differences were observed between the baseline and summary-only approaches.
CONCLUSION: Our results indicate that a structured clinical reasoning approach enhances LLM’s diagnostic accuracy. This method shows potential as a valuable tool for deriving diagnoses from free-text clinical information. The approach aligns well with established clinical reasoning processes, suggesting its potential applicability in real-world clinical settings.
