An R Shiny Application (SDOH) for Predictive Modeling Using Regional Social Determinants of Health Survey Responses

Abstract

Social determinants of health (SDoH) surveys are data sets that provide useful health-related information about individuals and communities. This study aims to develop a user-friendly web application that allows clinicians to get a predictive insight into the social needs of their patients before their in-patient visits using SDoH survey data to provide an improved and personalized service. The study used a longitudinal survey that consisted of 108,563 patient responses to 12 questions. Questions were designed to have a binary outcome as the response and the patient's most recent responses for each of these questions were modeled independently by incorporating explanatory variables. Multiple classification and regression techniques were used, including logistic regression, Bayesian generalized linear model, extreme gradient boosting, gradient boosting, neural networks, and random forests. Based on the area under the curve values, gradient boosting models provided the highest precision values. Finally, the models were incorporated into an R Shiny application, enabling users to predict and compare the impact of SDoH on patients’ lives. The tool is freely hosted online by the University of Kansas Medical Center's Department of Biostatistics and Data Science. The supporting materials for the application are publicly accessible on GitHub.

MortalityMinder: Visualization and AI Interpretations of Social Determinants of Premature Mortality in the United States

“…For example, African Americans are dying from COVID-19 at a higher rate across the country [4]. With rare exceptions [5], few interactive tools are available for stakeholders such as healthcare researchers, providers, payers, and policy makers to gain data-driven insights into which social determinants are associated with the trends of increasing mortality for states and counties of interest. While prior studies have used machine learning to predict and examine social determinants of health [6], this work identifies and visualize potential health disparities by combining a risk group analysis approach with interactive infographics.…”
