Contribution of free-text analysis to ARI detection.

*Performance of text-mining routines is usually reported using the term “Recall” instead of “Sensitivity” and “Precision” instead of “Positive Predictive Value”. Another common text-mining metric, the F-measure (2 * Precision * Recall/(Precision + Recall) is 29.9 for CDA #10.
Composition (black dot indicates that the component is included in the CDA) of ARI CDAs that combine parameters derived from structured and free-text EMR entries. Statistical performance was combined for both study sites. CDAs 3-12 seek increasing sensitivity; CDA 13-16 seek increasing PPV.
