Clinical Accuracy of Continuous Glucose Monitoring Immediately After Kidney Transplant in Patients With Type 2 Diabetes

Endocr PractPublished Diagnostic accuracy study

Authors' conclusion

CGM provided accurate blood glucose measurements compared with POCT and serum glucose values in patients with type 2 DM after kidney transplant. When used in this patient population, CGM devices have the potential to improve clinical outcomes through earlier detection and intervention for glycemic excursions.

Study context

Population
Kidney transplant recipients aged ≥18 years with T2D, immediate postoperative period; 82% male, mean age 58 ± 9.69 years, mean BMI 30 ± 6.41 kg/m², baseline mean HbA1c 6.7 ± 1.07%
Participants
327 vs 72
Comparison
Blinded continuous glucose monitoring (CGM) vs point-of-care testing (POCT) and serum glucose
  • CGM vs POCTn = 327
  • CGM vs serum glucosen = 72
Outcome
Accuracy of CGM vs POCT and serum glucose: bias, absolute relative difference and Clarke Error Grid Analysis
Follow-up
