OBJECTIVES/GOALS: Chronic kidney disease (CKD) affects nearly 40% of adults with diabetes. Our objective is to assess trends in risk factor control and use of 2022 ADA and KDIGO guideline-recommended medications. METHODS/STUDY POPULATION: Using data from 1988 to 2020 from the National Health and Nutrition Examination Survey, we will examine trends in sociodemographic risk factors and glycemic, blood pressure, and lipid control among adults with CKD and diabetes. Glycemic control will be defined as a hemoglobin A1c (HbA1c)<7%, blood pressure control will be examined at cutoffs of 130/80 and 120/80 mmHg, and lipid control will be defined as a fasting triglyceride level ≥150 mg/dL, a low-density lipoprotein (LDL) <100 mg/dL without atherosclerotic cardiovascular disease (ASCVD), or LDL<70 mg/dL if they have ASCVD. We will assess changes in the use of commonly used antidiabetic, antihypertensive, and lipid-lowering medications. RESULTS/ANTICIPATED RESULTS: We hypothesize that from 1988-2020, blood pressure control has improved while glycemic and lipid control has not improved among adults with diabetes and CKD. We expect decreases in sulfonylurea use and increases in DPP-4 inhibitor, metformin, ACE inhibitor, angiotensin receptor blocker, statin, and insulin use over time among those with diabetes and CKD. In addition, there is likely a significant gap between those who are eligible to use newer medications like SGLT2 inhibitors or GLP-1 receptor agonists and who are currently using them within this subpopulation. DISCUSSION/SIGNIFICANCE: This study will examine adherence to guideline-recommended management and identify gaps in care for adults with CKD and diabetes, which may inform how best to optimize medication use for cardiorenal protection in this high-risk patient population.
