Abstract: Objective: To evaluate the performance of a real-time continuous glucose monitor (CGM) in individuals with diabetes on peritoneal dialysis (PD). Research Design and methods: Thirty type 2 diabetes participants on continuous ambulatory peritoneal dialysis (CAPD) wore a Guardian Sensor™ 3 on the upper arm paired with Guardian Connect™ for 14 days. We compared CGM readings against Yellow Springs Instrument (YSI) venous glucose during an 8-hour in-clinic session with glucose challenge. Results: The mean absolute relative difference (MARD) was 10.4% (95% confidence interval: 9.6, 11.7) from 941 CGM-YSI matched pairs; 81.3% of readings were within 15/15% of YSI values in the full glycemic range. Consensus error grid analysis showed 99.9% of sensor values in zones A and B. There were no correlations between pH, uremia, hydration status and MARD. Conclusion: We showed satisfactory performance of a real-time CGM sensor in PD patients with diabetes, supporting future use to facilitate treatment decisions.
