Prospective Validation of an EHR-based Pancreatic Cancer Risk Model

Prospective Validation of an EHR-based Pancreatic Cancer Risk Model

Description
Description

To prospectively validate, implement in real-time, and assess performance of an EHR- based PDAC risk-prediction model. To test the hypothesis that our model will reliably predict PDAC in a real-time clinical setting, we will conduct a multi-center prospective cohort study, deploying the PDAC risk model within the TriNetX federated network database, and will take the following steps:

i) generate a risk prediction score for each individual under the care of 44 health care organizations (HCOs) in the USA ii) follow all individuals for up to 3 years to assess the primary end-point of PDAC development.

The following metrics will be used to test the discriminative performance and calibration of the EHR-based PDAC risk model in predicting incident PDAC, at the end of the 3-year period:

AUROC, sensitivity, specificity, PPV/NPV for assessing discrimination

Calibration: for assessing the accuracy of estimates, based on the estimated to observed number of events
