This paper presents a pipeline for extracting and annotating clinical findings from patient records (case reports) over time using large-scale language models (LLMs) for time-series analysis of healthcare data. We construct a text time-series corpus of 2,139 sepsis (Sepsis-3) patient records from the PubMed Open Access (PMOA) subset and validate the system through comparison with the I2B2/MIMIC-IV dataset. Using the O1-preview and Llama 3.3 70B Instruct models, we demonstrate a high event match rate (~0.75) and strong concordance (~0.93). However, we highlight the limitations of LLMs in temporal reconstruction, suggesting potential improvements through multimodal integration.
