The Use of Risk Prediction to Identify Patients at Risk for Chronic Kidney Disease: Patient and Provider Interventions for Patients at High Risk for Chronic Kidney Disease

This prospective, cluster-randomized trial is structured as a pragmatic study, embedding the outreach intervention within routine clinical workflows. The intervention reflects real-world provider-patient communication methods. The primary research aim is to evaluate, under typical practice conditions, whether structured notification strategies improve follow-up screening.

We will evaluate whether targeted provider and patient-directed communication increases completion of CKD disease lab testing (eGFR and uACR) among individuals identified as being at risk for having CKD based on the model developed in in Phase 1. We will identify up to 1,000 patients with high risk of having CKD. All patients' primary care providers (PCPs) will receive a message notifying them of patients' elevated risk status and the recommendation for CKD testing per standard practice. Additionally, we will randomly allocate providers whose patients will receive letters ( \~n=500 patients) and providers whose patients will receive a phone call ( \~n=250 patients).
