Programmatic Theme: Informatics Implementation
Abstract: Predictive models have been proposed for optimizing advanced care planning but are often not evaluated for their clinical utility. We describe a pre-deployment assessment of a mortality prediction model for its potential for improving advanced care planning (ACP) by comparing it to an existing clinical heuristic. The model significantly outperforms a clinical heuristic in detecting patients in high-need for ACP and provides an average of 2 months lead time over the heuristic for advanced care planning.
Learning Objective: Audience will learn methods for estimating incremental utility of a machine learning model over existing clinical heuristics.
