Tutorial: development of an online risk calculator platform

Xinge Ji, Michael W. Kattan

Abstract

Risk calculators are online tools developed for use by physicians in clinical settings to predict the risk of a clinical event, and as an aid in personalizing medical decision-making. Cleveland Clinic prediction models are listed at http://rcalc.ccf.org. We illustrate how we used R to create a risk calculator, and demonstrate the ease of using R, RStudio, and a Shiny package.
