Automated acuity scoring within a computer based medical record.

Abstract

This paper describes the initial development of a completely automated acuity scoring system that resides within the TMR bedside computing system at the Duke University Medical Center, Surgical Intensive Unit. The scoring system is based upon the APACHE II acuity scoring system and provides for the recalculation of acuity scoring at 12 hour intervals through the patient's ICU course. When comparing hand calculated versus computer generated acuity scores for 19 patients, discrepancies fell into three broad categories: 1) data available to the application differed from that available to the human scorer. 2) apparent transcription errors 3) data items lost or absent from the paper record. It remains to be determined if computer generated acuity scoring provides for a more accurate representation of the patient's acuity.
