ICU Mortality Prediction Using Long Short-Term Memory Networks
This work addresses early prediction of clinical outcomes for ICU patients, but it is incremental as it applies an existing method (LSTM) to a specific healthcare dataset.
The authors tackled ICU mortality prediction by applying LSTM networks to 6-hour time-frames of multivariate EHR data, achieving efficient results for predicting in-hospital mortality and length of stay.
Extensive bedside monitoring in Intensive Care Units (ICUs) has resulted in complex temporal data regarding patient physiology, which presents an upscale context for clinical data analysis. In the other hand, identifying the time-series patterns within these data may provide a high aptitude to predict clinical events. Hence, we investigate, during this work, the implementation of an automatic data-driven system, which analyzes large amounts of multivariate temporal data derived from Electronic Health Records (EHRs), and extracts high-level information so as to predict in-hospital mortality and Length of Stay (LOS) early. Practically, we investigate the applicability of LSTM network by reducing the time-frame to 6-hour so as to enhance clinical tasks. The experimental results highlight the efficiency of LSTM model with rigorous multivariate time-series measurements for building real-world prediction engines.
