Abstract

Chronic kidney disease (CKD) is a disease that gets worse over time and raises the risk of heart disease, lowers the quality of life, and puts a lot of strain on the healthcare system. Conventional diagnostic methods predominantly depend on static clinical biomarkers, including serum creatinine, estimated glomerular filtration rate, and albuminuria, which may not effectively detect subtle physiological decline in the initial stages. To fill this gap, this paper suggests a strong, easy-to-understand, and scalable multimodal deep learning framework that combines structured clinical laboratory features with simulated real-time physiological signals, such as changes in blood pressure and heart rate. A dual-branch neural architecture is constructed, comprising a multilayer perceptron that encodes tabular clinical features and a one-dimensional convolutional neural network that extracts temporal representations from vital-sign sequences. For CKD stage-wise classification, the learned embeddings are combined at the feature level. The proposed model achieves a test accuracy of 90% and a macro-F1 score of 0.86, outperforming clinical-only and vitals-only baselines, as shown by experimental evaluation. SHapley Additive exPlanations-based feature attribution and temporal attention visualizations make it possible to understand models better by showing clinically relevant biomarkers and hemodynamic patterns. Robustness testing with noisy vital signs and low-latency inference profiling shows that the framework is good for real-time renal risk monitoring and tele-nephrology uses.
