SOCIETY FOR MEDICAL DECISION MAKING ANNUAL MEETING 2020

Risk Prediction Profile for Microvascular Complications in Patients with Diabetes

Each year, 10,000 cases of blindness, 50,000 treatments for renal failure, and 73,000 lower-limb amputations occur in the US due to diabetes. To improve early and accurate diagnosis of the microvascular complications of diabetes, we used data from the 9-year Action to Control Cardiovascular Risk in Diabetes (ACCORD) clinical trial to develop a personalized risk profile for diabetic retinopathy, nephropathy, and neuropathy using multiple stacked-ensemble models.


The ACCORD study detailed 13 unique outcomes of microvascular complications for 10,251 patients, each with over 75 clinical and patient-reported variables. I tested over 600 combinations of pre-processing, unsupervised, and supervised model-building techniques. I used nested cross-validation (CV) to build and select models to increase validity and robustness. Performance metrics included the area under the receiver operating characteristics curve (AUC) and F1-score. I selected the 'best' model by minimizing the maximum regret among all performance metrics. 

​

Understanding the predictive power of data attributes and their influence on model performance informs a smarter framework for evidence-based model selection that is both robust to changes in patient population and accurate in a clinical setting.
