A Large Language Model Approach to Identifying Preoperative Frailty Among Older Adults From Clinical Notes

We report the development and validation of a classifier that detects older adults at risk for preoperative frailty from preoperative anesthesia clinical notes. Large language models can be used to accurately identify a difficult-to-quantify and multifactorial characteristic such as frailty in patients by using readily available unstructured information from clinical notes.
