Existing models for predicting mortality based on traditional Cox proportional hazard approach (CPH) often have low prediction accuracy.
This paper aims to develop a clinical risk model with good accuracy for predicting 1-year mortality in cardiac arrhythmias patients using random survival forest (RSF), a robust approach for survival analysis.
10,488 cardiac arrhythmias patients available in the public MIMIC II clinical database were investigated, with 3,452 deaths occurring within 1-year followups.
Forty risk factors including demographics and clinical and laboratory information and antiarrhythmic agents were analyzed as potential predictors of all-cause mortality.
RSF was adopted to build a comprehensive survival model and a simplified risk model composed of 14 top risk factors.
The built comprehensive model achieved a prediction accuracy of 0.81 measured by c-statistic with 10-fold cross validation.
The simplified risk model also achieved a good accuracy of 0.799.
Both results outperformed traditional CPH (which achieved a c-statistic of 0.733 for the comprehensive model and 0.718 for the simplified model).
Moreover, various factors are observed to have nonlinear impact on cardiac arrhythmias prognosis.
As a result, RSF based model which took nonlinearity into account significantly outperformed traditional Cox proportional hazard model and has great potential to be a more effective approach for survival analysis.
