Making Sense of CKD

§ Designed to help PCPs manage adult CKD patients

§ Emphasizes key considerations for evaluating and managing CKD patients:

§ Identifying patients at highest risk for progression to kidney failure

§ Slowing progression among these high-risk patients

§ Highlights useful resources:

§ Patient education materials

§ Clinical tools

§ Professional reference materials
