Glycemic Control and Cardiovascular Risk Factor Management in Adults With Type 2 Diabetes With and Without Chronic Kidney Disease Before Sodium-Glucose Cotransporter Protein 2 Inhibitors: Insights From the Diabetes Mellitus Status in Canada Survey

Abstract

ObjectivesOptimal control of cardiovascular risk factors in adults with type 2 diabetes (T2D) and chronic kidney disease (CKD) is challenging. Limited data are available from the primary care setting on achievement of guideline-recommended targets in this population before the use of sodium-glucose cotransporter protein 2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists. MethodsThe Diabetes Mellitus Status in Canada survey included 5,172 patients with T2D seen by primary care physicians (PCPs) in November 2012. We compared treatment targets and therapeutic interventions in patients with and without CKD. ResultsCompared with those without CKD (n=3,804), patients with CKD (n=1,368) were older, more likely to be female, had a longer duration of diabetes and had more vascular complications. Patients with CKD more frequently had a less stringent glycated hemoglobin (A1C) target of ≤8.0% set by PCPs (10.3% vs 20%, p<0.001), and fewer patients with CKD met the A1C target of ≤7.0% (50.9% vs 47.1%, p=0.016) than those without CKD. Both groups had a similar likelihood of achieving the blood pressure (BP) target of ≤130/80 mmHg (36.8% vs 34.8%, p=0.20), whereas patients with CKD more frequently achieved a low-density lipoprotein cholesterol target of ≤2.0 mmol/L (54.8% vs 61.3%, p<0.001). Overall, only 12.5% in both groups achieved all 3 targets (12.3% vs 13.3%, p=0.33). ConclusionsOnly 1 of 8 patients with T2D achieved optimal glycemic, BP and cholesterol targets, regardless of the presence or absence of CKD. Although more medical interventions were used in patients with CKD, a lower proportion achieved guideline-recommended targets for A1C. These findings provide a benchmark for future comparison.
