Key result
The graph convolutional network model effectively predicted 6-month readmission risk in patients with heart failure, achieving the highest area under the curve of 0.831 compared to other machine learning models.
Why the study?
Heart failure patients frequently face rehospitalization, but the effectiveness of existing readmission prediction models tailored specifically to the Chinese population remains limited.

Does a graph convolutional network model accurately predict 6-month readmission risk in Chinese patients with heart failure?
A graph convolutional network model effectively predicts the 6-month risk of readmission in Chinese patients with heart failure, outperforming traditional machine learning algorithms.
Background: Patients with heart failure frequently face the possibility of rehospitalization following an initial hospital stay, placing a significant burden on both patients and health care systems. Accurate predictive tools are crucial for guiding clinical decision-making and optimizing patient care. However, the effectiveness of existing models tailored specifically to the Chinese population is still limited. Objective: This study aimed to formulate a predictive model for assessing the likelihood of readmission among patients diagnosed with heart failure. Methods: In this study, we analyzed data from 1948 patients with heart failure in a hospital in Sichuan Province between 2016 and 2019. By applying 3 variable selection strategies, 29 relevant variables were identified. Subsequently, we constructed 6 predictive models using different algorithms: logistic regression, support vector machine, gradient boosting machine, Extreme Gradient Boosting, multilayer perception, and graph convolutional networks. Results: The graph convolutional network model showed the highest prediction accuracy with an area under the receiver operating characteristic curve of 0.831, accuracy of 75%, sensitivity of 52.12%, and specificity of 90.25%. Conclusions: The model crafted in this study proves its effectiveness in forecasting the likelihood of readmission among patients with heart failure, thus serving as a crucial reference for clinical decision-making.

Jiang et al. (2024) conducted an observational in Heart failure (n=1,948). Graph convolutional network (GCN) model vs. Traditional machine learning models (LR, SVM, GBM, XGBoost, MLP) was evaluated on 6-month hospital readmission prediction (AUC) (AUC 0.831, 95% CI 0.813-0.849, p=<0.001). The graph convolutional network model effectively predicted 6-month readmission risk in patients with heart failure, achieving the highest area under the curve of 0.831 compared to other machine learning models.
