The document summarizes a study conducted by the Renal Physicians Association (RPA) and Duke Center for Clinical Health Policy Research (DCCHPR) to test an Advanced Chronic Kidney Disease (CKD) Patient Management Toolkit in 10 nephrology practices across the US. The study aimed to evaluate the utility of the toolkit, assess care patterns and changes needed to improve care, and evaluate the impact on conforming to CKD guideline recommendations. The 10 sites were divided into two groups, with one group implementing the toolkit while the other served as a comparator. The study provided a unique opportunity to involve diverse practices and patients to understand challenges in CKD management and insights for the future.
