Bayesian-network-based method and system for detection of clinical-laboratory errors using synthetic errors
First Claim
Patent Images
1. A method for detecting errors in a clinical-laboratory-analysis-results data set, the method comprising:
- receiving a cleaned clinical-laboratory-analysis-results data set;
introducing synthetic errors into the cleaned clinical-laboratory-analysis-results data set to produce a training data set and a test data set;
inferring a Bayesian network or modified Bayesian network, based on the training data set, for detecting errors;
evaluating and optimizing the Bayesian network or modified Bayesian network, using the test data set to produce a final Bayesian network or modified Bayesian network; and
using the final Bayesian network or modified Bayesian network to detect errors in subsequently received clinical-laboratory-analysis-results data sets.

Abstract
Embodiments of the present invention include methods and systems for analyzing clinical-laboratory results and data in order to detect erroneous clinical-laboratory results. Embodiments of the present invention employ Bayesian networks and modified Bayesian networks that are constructed using cleaned clinical-laboratory results into which various types of synthetic errors have been introduced and that are optimized using different, cleaned clinical-laboratory results into which synthetic errors have been introduced.
