Researchers at the University at Buffalo developed Semantic Clinical Artificial Intelligence (SCAI), an AI tool that scored 95.2% on Step 3 of the USMLE, outperforming other AIs like GPT4 Omni (90.5%) and most doctors. Using semantic reasoning with a knowledge base of 13 million medical facts, SCAI can engage in conversations to provide accurate answers. Designed to augment rather than replace physicians, it aims to enhance patient safety, improve care access, and democratize specialty care.
SCAI Outperforms Other AI Models in Medical Question Answering
SCAI leverages semantic reasoning to process complex medical information with precision. It constructs semantic networks using 13 million medical facts and triples, such as “Penicillin treats pneumococcal pneumonia,” enabling more effective reasoning in clinical contexts. This structured approach enhances accuracy and reliability compared to traditional generative AI tools that rely on pattern recognition.
The integration of knowledge graphs further improves SCAI’s capabilities by mapping relationships between medical concepts. These graphs facilitate a deeper understanding and application of evidence-based medicine, ensuring responses are grounded in current data and reducing errors. Retrieval-augmented generation ensures up-to-date information is used to refine answers, increasing trustworthiness.
SCAI’s semantic reasoning supports handling nuanced clinical questions by analyzing context and relationships within medical knowledge. This capability is particularly valuable in specialties requiring complex decision-making, as it helps bridge gaps between general and specialized care. By providing access to specialized medical information, SCAI empowers primary care providers and patients, democratizing specialty care and enhancing healthcare accessibility.
Lead researcher Peter Elkin emphasizes that AI tools like SCAI are designed to augment, not replace, physicians. This perspective addresses concerns about AI replacing human roles, highlighting its role as a supportive tool in advancing medical practice through technology.
