A systematic review of large language model (LLM) evaluations in clinical medicine
Large Language Models (LLMs) are poised to transform clinical medicine by enhancing diagnostics, decision support, and medical education. This systematic review analyzes 761 studies evaluating LLMs, revealing a dominant focus on general-domain LLMs (93.55%) like ChatGPT and GPT-4, with accuracy as the primary evaluation parameter (21.78%). While demonstrating significant potential, the research highlights critical gaps, including the underrepresentation of specialized medical LLMs (6.45%), variability in evaluation frameworks, and ethical concerns. Standardized, context-specific evaluations are crucial for safe and effective integration.

LLMs in Surgical Specialties: A Deep Dive
Scenario: Surgery emerged as the most frequently evaluated specialty (28.2% of all studies), with ophthalmology (25.0%), orthopedics (20.0%), and urology/otolaryngology (14.1% each) leading subspecialties. This indicates a strong focus on LLM utility in surgical contexts, potentially for pre-operative planning, diagnostic support, and post-operative care.
Challenge: However, general surgery (5.5%) and other critical subspecialties like neurosurgery and vascular surgery were significantly underrepresented, highlighting a gap in research coverage for broad surgical applications.
Outcome: Future research must strategically align LLM evaluations with the specific needs of these underserved surgical domains to unlock their full potential and ensure comprehensive integration across all surgical practices.
1.9%
Cardiology Underrepresentation
Despite its global burden, cardiology received only 1.9% of LLM evaluations, indicating a critical gap in research focus for this high-impact specialty.

Your AI Implementation Roadmap
A structured approach to integrate AI solutions into your enterprise, ensuring maximum efficiency and impact.
Phase 1: Needs Assessment & Pilot (1-3 Months)
Identify high-impact clinical areas for LLM integration. Conduct pilot studies with a small group of users to gather initial feedback on accuracy, safety, and workflow integration. Define clear success metrics.
Phase 2: Customized Model Development & Validation (3-6 Months)
Fine-tune LLMs with domain-specific medical data. Develop robust validation frameworks, involving expert human review, to ensure reliability and ethical compliance. Address biases and data security concerns.
Phase 3: Scaled Deployment & Training (6-12 Months)
Integrate validated LLMs into existing clinical systems. Provide comprehensive training for healthcare professionals on LLM usage, interpretation of outputs, and ethical guidelines. Establish continuous monitoring for performance and safety.
Phase 4: Continuous Improvement & Regulatory Alignment (Ongoing)
Implement feedback loops for iterative model refinement. Stay updated with evolving regulatory standards and best practices for AI in healthcare. Expand LLM applications to new specialties based on validated outcomes.
