Using Time Series Analysis to Predict Cardiac Arrest in a PICU.

Objectives: To build and test cardiac arrest prediction models in a PICU, using time series analysis as input, and to measure changes in prediction accuracy attributable to different classes of time series data.

Design: Retrospective cohort study.

Setting: Thirty-one bed academic PICU that provides care for medical and general surgical (not congenital heart surgery) patients.
