A clustering approach for detecting implausible observation values in electronic health records data

A clustering approach for detecting implausible observation values in electronic health records data

Abstract Background Identifying implausible clinical observations (e.g., laboratory test and vital sign values) in Electronic Health Record (EHR) data using rule-based procedures is challenging. Anomaly/outlier detection methods can be applied as an alternative algorithmic approach to flagging such...
