Chart Review

Measure agreement between chart reviewers.

Whether your chart annotations come from humans, machine-learning, or coded data like ICD-10, chart-review can compare them to reveal interesting statistics like:

Accuracy

• F1-score (agreement)
• Sensitivity and Specificity
• Positive (PPV) or Negative Predictive Value (NPV)
• False Negative Rate (FNR)

Confusion Matrix

• TP = True Positive (type I error)
• TN = True Negative (type II error)
• FP = False Positive
• FN = False Negative
