The Rapid Expansion of LLMs in Clinical Medicine
Clinical evaluations of large language models (LLMs) have rapidly expanded since 2022, yet their evidence base remains opaque due to the overwhelming volume of studies and challenges for manual curation. This LLM-assisted review identified over 4,600 peer-reviewed studies in clinical medicine between January 2022 and September 2025, averaging 3.2 papers per day. The vast majority of these studies focus on simulated scenarios or exam-style tasks, highlighting a critical gap in real-world clinical evidence. ChatGPT and related OpenAI models dominate the landscape, accounting for 65.7% of evaluated models.
Methodology: LLM-Assisted Systematic Review Process
Our review leveraged a frontier LLM (GPT-5) to screen and categorize an immense volume of medical literature, overcoming the scalability issues of manual reviews. This AI-powered approach allowed for the identification and tiering of studies based on their evidence quality, from gold-standard prospective trials (Tier S) to knowledge retrieval tasks (Tier III). Human validation confirmed high agreement, demonstrating the potential of LLMs to accelerate systematic review processes in critical domains like healthcare.
Performance Insights: LLMs vs. Human Experts
Across 1,046 head-to-head comparisons, LLMs outperformed humans in 33% of comparisons, with performance strongly influenced by task realism and the human expert's training level. LLMs demonstrated superior performance in knowledge-based tasks on synthetic data (Tier III) compared to real-world clinical scenarios (Tier I). This indicates that while LLMs excel in knowledge synthesis, their application in complex, real-world clinical decision-making still requires substantial development and validation.
Strategic Recommendations for Enterprise AI Adoption
Despite the rapid growth of LLMs in medicine, rigorous, patient-centered evidence remains scarce. We strongly recommend prioritizing larger prospective trials before widespread clinical adoption. Enterprises should focus on developing open-source models and open-access datasets to enhance reproducibility and foster community scrutiny. Furthermore, careful consideration of the human comparator's expertise and the realism of the task is crucial for valid performance evaluations. A tiered research roadmap, moving from basic knowledge assessment to real-world RCTs, is essential for responsible and effective AI integration.

Statistical Analysis & Reporting
| Tier | Description | Key Characteristics for Enterprise Evaluation |
|---|---|---|
| Tier S (Gold Standard) | Real-world, prospective, randomized, controlled evaluations in live clinical environments. |
|
| Tier I (Real Data) | Retrospective or prospective analyses on real, never-before-seen clinical data. |
|
| Tier II (Simulated Scenarios) | Simulated clinical situations, open-ended free-response questions, subjective patient ratings. |
|
| Tier III (Knowledge-Based) | Board exams, multiple-choice exams, case-studies with clear-cut answers (e.g., diagnosis). |

Case Study: Early RCT in Smoking Cessation
The earliest identified Tier S study, published in July 2024, was a randomized controlled trial comparing a custom-designed LLM (QuitBot) against a national cancer institute text-line for smoking cessation. This trial found that QuitBot yielded significantly higher smoking cessation rates (odds ratio 2.58, P=0.005) than the control. This marks not only the first RCT involving LLMs but also the first to demonstrate an LLM outperforming an existing, well-established control method. This case highlights the transformative potential of LLMs in direct patient care when rigorously validated.
