| Περίληψη: | Large language models (LLMs) represent a type of generative artificial intelligence (GenAI) that generate and interpret text, with some LLMs able to process multimodal content (e.g., images, audio, video), and can be deployed as part of agents to perform users' tasks. LLMs can perform natural language processing functions such as summarization, translation, and extraction giving them the potential to enhance and scale pharmacoepidemiological and real-world research by performing tasks such as literature review, data extraction, and medical writing. Despite the growing integration of GenAI tools into research workflows, their technical foundations and methodological implications remain unfamiliar to many pharmacoepidemiologists, who are often responsible for the reliability and accuracy of research that relies on these tools. This paper aims to inform pharmacoepidemiologists about the capabilities and limitations of LLMs to support responsible integration into the field of pharmacoepidemiology, providing an intuitive overview of how LLMs work, focusing on training and text generation, and reviews current and emerging applications in drug effectiveness and safety research and epidemiology. The article addresses challenges associated with LLM use in real-world evidence generation, including concerns regarding reproducibility, bias, hallucinations, plagiarism, data privacy, and the need for validation.

Large language models (LLMs) are one example of this technology and are designed to generate and interpret text, with some LLMs able to process multimodal content, including images, audio, and video. In drug safety and effectiveness research, these models can help with tasks such as reviewing previously published studies, extracting information from large collections of medical records, and drafting reports about new research. LLMs are created by training them on very large amounts of text, although many contemporary models are also trained on images, audio, and other modalities. During training, the model reads text and repeatedly tries to predict the next word. By learning from its mistakes over time, the model gradually improves. Although LLMs show considerable promise, they must be used with caution in drug safety and effectiveness research. These systems can make mistakes and may reflect biases that exist in the data they were trained on. For this reason, careful testing and ongoing human oversight are essential. |
