Large Language Models and Medical AI Systems for Healthcare Diagnosis: A Systematic Review

Vollständiger Abstract

Worum geht es in dieser Arbeit?

The rapid growth of artificial intelligence systems (AI systems) has increased interest in the use of patient care and clinical decision-making processes. There is some uncertainty regarding their reliability and safety in clinical practice. A more detailed systematic review of literature examining LLMs applied to healthcare diagnosis was conducted. A PRISMA-based systematic review has been carried out of relevant literature published in the major databases for the years 2022–2025. Key findings include a growing trend to develop multimodal models based on diverse input modalities, combining LLM models with other models as part of clinical workflows. The Usage of complementary methodologies such as retrieval-augmented generation, knowledge graphs, and federated learning is highly expanding, particularly in enhancing the efficiency and accuracy of clinical decision-making processes. Significant challenges such as hallucinations, bias, prompt sensitivity, limited explainability, and inadequate clinical validation continue to pose major obstacles. Although promising, LLM-based systems are not yet reliable enough for autonomous medical diagnosis. Overall, this review contains multiple recommendations for future research in many areas (e.g., LLMs) to ensure a high level of safety, transparency, and clinical applicability for LLMs and other AI/ML-related technologies and devices.
