Abstract
I will discuss my recent paper, “Early prediction of circulatory failure in the intensive care unit using machine learning” (Nature Medicine, 2020). Using a large, high-resolution dataset from a Swiss ICU we built a classifier of near-term (8-hour) circulatory failure in ICU patients with invasive blood pressure monitoring. The model, using gradient-boosted trees, achieved strong predictive performance (AUC >0.9; precision ~30% at 90% recall), with generally consistent performance across patient cohorts. A key component of this work was a careful data processing and feature extraction pipeline, which I will be happy to discuss in detail.
