Summary
A new tool uses electronic health records to predict multiple sclerosis (MS) relapse risk. This machine learning algorithm accurately forecasts future relapses, aiding treatment decisions for MS patients.
Area of Science:
- Neurology
- Medical Informatics
- Machine Learning
Background:
- Multiple Sclerosis (MS) lacks a validated relapse risk prediction tool for guiding treatment.
- Electronic Health Records (EHR) offer readily accessible data for clinical decision-making.
Purpose of the Study:
- To develop and validate a clinical tool for predicting MS relapse risk using EHR data.
- To create a practical, point-of-care tool for MS management.
Main Methods:
- Developed a two-stage machine learning algorithm using EHR data from 2006-2016.
- Utilized L1-regularized logistic regression (LASSO) for relapse phenotyping and risk prediction.
- Validated the model on an independent cohort of 186 MS patients.
Main Results:
- The final model, including age, disease duration, and imputed relapse history, achieved an AUC of 0.707.
- Model performance was superior to baseline and comparable to using actual relapse history.
- Predicted relapse risk decreased with longer disease duration and older age.
Conclusions:
- A novel EHR-based machine learning algorithm accurately predicts 1-year MS relapse risk.
- The tool demonstrates applicability at the point of care for MS treatment guidance.
- This two-stage EHR prediction approach may extend to other neurological conditions.
