Model Utility in Healthcare Delivery

Model PerformanceAUC, Sensitivity, Specificity, PPV, etc.
Data requirementsShorter observation window, fewer features
Model coherence and translationTransparency, interpretability, clinical and etiologic utility, actionability
Model purpose and validationDiagnosis, prognosis, risk management, risk communication, treatment/intervention indication
Ease of updatingEase of implementation, platform utilities
Ease of use/accessUser access, requirements, and burden;
integration with workflow
  • AUC indicates area under the receiver operating characteristic curve; and PPV, positive predictive value.
