Clinical Notes Reveal Physician Fatigue

no code implementations5 Dec 2023 Chao-Chun Hsu, Ziad Obermeyer, Chenhao Tan

Finally, the model indicates that notes written about Black and Hispanic patients have 12% and 21% higher predicted fatigue than Whites -- larger than overnight vs. daytime differences.

The Algorithmic Automation Problem: Prediction, Triage, and Human Effort

1 code implementation28 Mar 2019 Maithra Raghu, Katy Blumer, Greg Corrado, Jon Kleinberg, Ziad Obermeyer, Sendhil Mullainathan

In a wide array of areas, algorithms are matching and surpassing the performance of human experts, leading to consideration of the roles of human judgment and algorithmic prediction in these domains.

A Probabilistic Model of Cardiac Physiology and Electrocardiograms

no code implementations1 Dec 2018 Andrew C. Miller, Ziad Obermeyer, David M. Blei, John P. Cunningham, Sendhil Mullainathan

An electrocardiogram (EKG) is a common, non-invasive test that measures the electrical activity of a patient's heart.

Measuring the Stability of EHR- and EKG-based Predictive Models

no code implementations1 Dec 2018 Andrew C. Miller, Ziad Obermeyer, Sendhil Mullainathan

In a predictive task, we show that EKG-based models can be more stable than EHR-based models across different patient populations.

Direct Uncertainty Prediction for Medical Second Opinions

no code implementations4 Jul 2018 Maithra Raghu, Katy Blumer, Rory Sayres, Ziad Obermeyer, Robert Kleinberg, Sendhil Mullainathan, Jon Kleinberg

Our central methodological finding is that Direct Uncertainty Prediction (DUP), training a model to predict an uncertainty score directly from the raw patient features, works better than Uncertainty Via Classification, the two-step process of training a classifier and postprocessing the output distribution to give an uncertainty score.
