Calibration Metrics for Gap Analysis

Metric	Calculation
Total Mismatch (Total Error)	wrong/total = (incorrect + partial/2 + missing + spurious)/(correct + partial+ incorrect+ missing + spurious)
Undergeneration	missing/possible = missing/(correct + partial+ incorrect + missing)
Overgeneration	spurious/actual = spurious/(correct + partial + incorrect + spurious)
Substitution	(incorrect + partial/2)/(correct + partial + incorrect)
Codes and Definitions: CDE = Clinical Data Element Match (Correct): CDE on Documentation Artifact ≠ CDE from Reference model Partial Match (Partial): CDE on Documentation Artifact ~= CDE from Reference model (variation between definitions exists but are intended to capture same clinical concept) Conflicting (Incorrect): CDE on Documentation Artifact 4- CDE from Reference model Extra (Spurious): CDE is on Documentation Artifact but does is not represented in Reference model Missing: CDE is not represented on Documentation Artifact but does exist in Reference model
