While it has been well known in the ML community that deep learning models suffer from instability, the consequences for healthcare deployments are under characterised.

Machine learning for dynamically predicting the onset of renal replacement therapy in chronic kidney disease patients using claims data

no code implementations3 Sep 2022 Daniel Lopez-Martinez, Christina Chen, Ming-Jun Chen

In this work, we present a machine learning model that dynamically identifies CKD patients at risk of requiring RRT up to one year in advance using only claims data.
