How I wired GPT-OSS with custom tools to make clinical data actually usable.
In my last experiment, I ran OpenAI’s new local model on my laptop and it extracted JSON from clinical notes surprisingly well. However, these raw extractions are not very actionable. We successfully got a lot of information out of a discharge summary, like the primary diagnosis, relevant lab results and follow-up appointments scheduled. But this information is not actionable yet: we need clinical reasoning, normalization, and interoperability.
This article details the development of three tools built to enhance the usability of clinical data extracted from AI models, focusing on transforming raw outputs into structured, EHR-ready information through processes like abnormal lab detection, follow-up gap checking, and diagnosis normalization with UMLS, ultimately demonstrating the effectiveness of local AI models in clinical reasoning.
