Scalable Clinical Data Infrastructure and Comparative ML Evaluation for Hospitalisation Risk Prediction in Elderly Patients with Multiple Long-Term Conditions using CPRD
AI InsightThis paper builds scalable patient timeline infrastructure on CPRD Aurum to predict 12-month hospitalisation risk for elderly multimorbid patients. The key change is systematic benchmarking of TG-CNN against LASSO logistic regression and random forests, rather than assuming deep learning superiority. This suggests EHR prediction research is returning to rigorous baseline validation, where simpler interpretable models may remain competitive.Key TakeawayShift from assumed deep learning superiority to systematic benchmarking against interpretable ML baselines.Why It MattersProvides a fair comparison framework on large real-world EHR data, directly addressing whether deep learning truly outperforms traditional models in clinical prediction.Who's Affected- AI ResearchersProvides reusable EHR data pipeline and multi-model benchmarks to re-evaluate actual deep learning gains.
- Healthcare IndustryHelps medical institutions understand model selection, prioritizing interpretability over complex architectures.
- DevelopersThree-tier framework for 260 conditions offers reference for disease coding and feature engineering.
What's NextWatch whether the benchmark shows simple models outperform TG-CNN and whether the CPRD pipeline is widely adopted by subsequent research.Importance 75/100
