Westgard Online QC Trainer Tool

James O. Westgard and Paul Schilling

This is a training and education tool for quality control in healthcare laboratories. It is designed to test the user in their interpretation of control charts. Specifically, levey-jennings control charts with data pointed that will simulate a given mean, standard deviation, and certain out-of-control situations.

Users will be presented with graphic display of control points, with the different lines drawn on the chart. Then users will have the opportunity to select which violation, if there is one, has occured. The tool will correct the user, in case of incorrect interpretations.

Please let us know what you think of them.
