Can machine learning models accurately predict social isolation in maintenance hemodialysis patients?
A Random Forest machine learning model can accurately predict the risk of social isolation in maintenance hemodialysis patients, identifying heart failure and psychosocial factors as key predictors.
ML prediction of social isolation risk feasible in MHD; leaves open prospective validation before clinical adoption.
Background This study aims to develop and validate a machine learning-based risk prediction model for social isolation in maintenance hemodialysis (MHD) patients, and at the same time determine the key risk factors. Method 362 patients with MHD were recruited from a tertiary hospital in Shanghai and randomly divided into the training group and the detection group. We implemented and compared seven machine learning algorithms: Random Forest (RF), Decision Tree (DT), K-Nearest Neighbor (KNN), Logistic Regression (LR), Resilient Network (EN), Extreme Gradient Boosting (XGB), and Support Vector Machine (SVM). Result In our MHD cohort, the incidence of social isolation was 45.856%. The comparative analysis shows that RF is the best prediction model (AUC = 0.95). Feature importance analysis identified significant predictors: Place of residence (1.277), Heart failure (HF) (0.559), Anxiety (0.306), Monthly household income (0.269), Age (0.255) Sleep condition (0.138). Conclusion The prediction model based on RF has a good effect in identifying the social isolation risk of MHD patients. These findings enable clinicians to stratify high-risk populations and implement timely and targeted intervention measures, effectively reducing the risk of adverse consequences. Future multicenter studies should validate these results in larger cohorts.

Li et al. (2026) conducted a cross-sectional in Maintenance hemodialysis (n=362). Random Forest model vs. Other machine learning models was evaluated on AUC for predicting social isolation. The Random Forest machine learning model effectively predicted the risk of social isolation in maintenance hemodialysis patients with an AUC of 0.95.
