Materials necessary for the "Patient-Level Prediction Tutorial".

Description & Objectives

This workshop is for researchers who want to design prediction studies for precision medicine and disease interception using the OHDSI tools and programmers who want to implement and execute prediction studies using the OHDSI methods library.

The participants will define their own prediction problem and will work on this as a group. The course starts with an introduction to Patient-Level Prediction, after which the OHDSI Framework is explained in detail. Driven by an actual use case the usage of the tools are demonstrated.

Course prerequisites: knowledge of OMOP CDM and Vocabularies and either 1) epidemiologic knowledge understanding of how to define cohorts or 2) R programming skills.

Participants are encouraged to watch these tutorials from past years in preparation for the tutorial:

A common area of confusion in the field is the difference between explanatory models – as would be used for causal inference in population-level effect estimation - and predictive models – as we are teaching you here to use for patient-level prediction. The paper by Shmueli and Koppius provides a nice summary of some of the conceptual distinctions in problem formulation, objective setting, model fitting, and results evaluation.

For those who prefer a video to a paper, here’s a nice presentation by Dr. Shmueli that covers most of the points in her paper.

Predictive models in observational data are becoming increasingly popular, but as a field, we are not consistently applying best practices in their execution or reporting. This recent review by Goldstein et al evaluates the predictive models observed in the literature, highlighting common pitfalls that we hope to teach you to avoid, and offering suggestions that may resonate with you as you look to design and implement your own models or review literature from predictive models built by others.
