Algorithm Type:
Case, Control
Institution:
Implementation Details:
Randomly selected 50 cases and 50 controls for abstraction. One control subsequently became invalid in a later version of the algorithm, so they are excluded from the results below. Marshfield used a modified algorithm comprising of a combination of both diagnoses and NLP which is outlined in the attached document entitled eMERGE II Venous Thromboembolism Phenotype Marshfield.docx (see below).
Phenotype:
Cases (50) | Actual Class (Expectation) | |
Predicted Class (Observation) |
True Positive: 49.00 |
False Positive: 1.00 |
Case Positive Predictive Value:
98%

Control (49) | Actual Class (Expectation) | |
Predicted Class (Observation) |
True Positive: 49.00 |
False Positive: 0.00 |
Control Positive Predictive Value:
100%
