Abstract

Delirium is common in the intensive care unit (ICU) and associated with longer ICU and hospital stays as well as worse patient outcomes including long-term cognitive impairment. Early prediction of impending delirium can lead to efficient allocation of ICU resources and improved patient outcomes via preventive care. Based on rich clinical data from over 43,000 ICU admissions in Alberta, we developed deep learning-based models capable of predicting delirium in the next two 12-hour windows, with new predictions generated every 12 hours. Our best model based on gated recurrent units resulted in areas under the receiver operating characteristic curve around 0.9.

Learning Objectives

By the end of this session, attendees will:

• Understand delirium as a major clinical problem in the intensive care unit;
• Learn how recurrent deep learning can be utilized to predict impending delirium in the intensive care unit;
• Appreciate the challenges surrounding feature engineering and hyperparameter tuning when granular electronic health record data are used.
