Accuracy of Continuous Glucose Monitoring in Hemodialysis Patients With Diabetes
Performance · Accuracy of CGM vs blood glucoseResult — go to the resultMean difference (Bland-Altman) ∼+15 mg/dLAuthors' conclusion
In hemodialysis patients with diabetes, although MARD values were higher than traditional optimal analytic performance thresholds, error grids showed nearly all CGM values were in clinically acceptable zones. Further studies are needed to determine whether CGM improves outcomes in hemodialysis patients.
