Model Development & Scientific ValidationDevelopment of a Continuous Measure of Patient Acuity Across All Diseases, Conditions
The Rothman Index (RI) is at the forefront of predictive analytics in healthcare. The RI is the only general measure of patient condition, and is integral to an array of effective predictive analytics in healthcare. It leverages the investment hospitals have made in electronic health records (EHRs), utilizing existing, real-time data to quantify and visualize patient acuity and risk.
The RI is based on a heuristic model that uses a range of physiological measures, including labs, vitals, and most importantly nursing assessments. The model transforms each input into a common representation of univariate risk, allowing heterogeneous data to be summed, solving the data fusion problem. The result is a continuous measure of patient condition, integrated into the EHR, computed on a real-time basis across all conditions, diseases and care settings.
The RI correlates well with many measures of risk, including:
