# External Validation of an EHR-Based Model for Risk of Patient No-Show in Primary Care

## TL;DR

This study tests how well an EHR-based model predicts when patients will miss primary care appointments, including differences by race and ethnicity.

## Contribution

The paper provides an external validation of an EHR-based model for predicting patient no-shows, including performance by race and ethnicity.

## Key findings

- The model showed good overall performance in predicting nonattendance.
- Performance varied by race and ethnicity, highlighting potential disparities.
- The results suggest the model can be useful in real-world clinical settings.

## Abstract

This prognostic study evaluates the performance of an electronic health record (EHR)–based model for predicting nonattendance at primary care appointments overall and by race and ethnicity.
