Insights
Emergency visits and prolonged hospital stays are key predictors of death in chronic kidney disease (CKD) patients. AI-driven models can help assess prognosis, guiding timely interventions for better patient outcomes.
Area of Science:
- Nephrology
- Artificial Intelligence in Healthcare
- Public Health
Background:
- Chronic kidney disease (CKD) prevalence is increasing globally, contributing significantly to mortality.
- Traditional statistical methods are being augmented by AI for predicting mortality factors in CKD.
- Further AI research is crucial for understanding CKD patient death determinants.
Purpose of the Study:
- To identify key factors associated with mortality in CKD patients using machine learning.
- To develop a deep learning-based predictive model for assessing death risk in CKD.
Main Methods:
- Utilized data from the Korea Disease Control and Prevention Agency (2016-2021).
- Applied Least Absolute Shrinkage and Selection Operator (LASSO) regression to identify significant mortality predictors.
- Developed a deep learning model incorporating LASSO-selected variables.
Main Results:
- Identified eight factors influencing death, including length of hospital stay, emergency admission, age, severity-adjusted score, and regional differences.
- The deep learning model achieved high accuracy (96.84%) with a low loss value (0.1207).
Conclusions:
- Emergency visits and prolonged hospital stays are significant predictors of mortality in CKD.
- Regular nephrology monitoring and timely renal replacement therapy are crucial for risk mitigation.
- An AI-based predictive model using general characteristics can aid rapid prognosis assessment.
Objectives:
The prevalence of chronic kidney disease (CKD) continues to rise, making it one of the leading causes of death worldwide. Recent advances in medical and health research have progressed beyond traditional statistical methodologies, increasingly leveraging artificial intelligence to identify and predict factors influencing mortality. Further AI-based research is therefore essential to deepen understanding of the determinants of death among CKD patients.
Methods:
This study used data from the Korea Disease Control and Prevention Agency's in-depth survey of patients discharged between 2016 and 2021. Least absolute shrinkage and selection operator (LASSO) regression, a machine learning technique, was applied to identify significant factors associated with death in CKD patients. These selected variables were then incorporated into a deep learning-based predictive model.
Results:
Eight factors influencing death were identified, including length of hospital stay (coefficient = 0.023), emergency admission (0.016), age (0.013), severity-adjusted score (0.008), and regional differences (0.003). The developed deep learning model achieved a loss value of 0.1207 and an accuracy of 96.84%.
Conclusions:
This study identified emergency visits and prolonged hospital stays as key predictors of death in CKD patients. To mitigate these risks, regular monitoring by nephrology specialists and timely initiation of renal replacement therapy are essential. Age also emerged as a critical determinant, emphasizing the importance of age-stratified clinical guidelines amid global aging trends. The high-performing, simplified predictive model based on general characteristics offers a valuable tool for rapid prognosis assessment in primary and secondary healthcare settings.
