Predicting hospital mortality for ICU patients: time series analysis

Research output: Contribution to journalArticle

Current mortality prediction models and scoring systems for Intensive Care Unit (ICU) patients are generally usable only after at least 24 or 48 hours of admission as some parameters are unclear at admission. However, some of the most relevant measurements are available shortly following admission. It is hypothesized that outcome prediction may be made using information available in the earliest phase of ICU admission. This study aims to investigate how early hospital mortality can be predicted for ICU patients. We conducted a thorough time-series analysis on the performance of different data mining methods during the first 48 hours of ICU admission. The results showed that the discrimination power of the machine learning classification methods after 6 hours of admission outperformed the main scoring systems used in intensive care medicine (Acute Physiology and Chronic Health Evaluation, Simplified Acute Physiology Score and Sequential Organ Failure Assessment) after 48 hours of admission.
