What insights can be obtained from Temporal Physiological Data-sets collected during Intensive Care for Head-Injury patients (2001) [1 citations — 1 self]

Abstract:
At the 1999 AIME Conference [1] we reported a decision tree study on a subset of data, including time series physiological data, admissions characteristics, and outcome after traumatic head injury. That study analysed total duration for which patients had, for example, raised Intracranial Pressure, but it did not consider temporal relationships between various physiological and clinical events. In this study, we have addressed that issue in a number of ways. Firstly, by asking clinicians to make predictions of expected outcome based on complete physiological and clinical data. Secondly, repeating the exercise with a reduced (more compact) representation for the physiological data. Thirdly, patterns were generated, including "adjacent " physiological parameters and clinicians were asked if they are likely/very unlikely to cause a particular major physiological event or outcome. Finally, we implemented a module to test patterns of the form: IF X happens then Y will happen between T1-T2 against patient time-series data. Results of all these studies have so far not been conclusive; more analyses particularly with the temporal patterns are currently in progress.
