Evaluation of a Fourth-Generation Subcutaneous Real-Time Continuous Glucose Monitor (CGM) in Individuals With Diabetes on Peritoneal Dialysis
Authors' conclusion
We showed satisfactory performance of a real-time CGM sensor in PD patients with diabetes, supporting future use to facilitate treatment decisions.
Study context
- Population
- Participants with T2D on continuous ambulatory peritoneal dialysis (PD)
- Participants
- 30 participants
- Comparison
- CGM vs Yellow Springs Instrument (YSI) venous glucose
- Guardian Sensor 3n = 30
- Outcome
- Accuracy of CGM vs YSI venous glucose
- Follow-up
- 8-h in-clinic session with glucose challenge
Methodological details14-day sensor wear, 8-h in-clinic session with glucose challenge
- 14-day sensor wear
- 8-h in-clinic session with glucose challenge
Performance
As reported in the abstract
Mean absolute relative difference (MARD) (95% CI 9.6, 11.7), 941 CGM-YSI matched pairs
10.4%
Readings within %15/15 of YSI values, full glycemic range
81.3%
Consensus error grid: sensor values in zones A and B
99.9%
Further findings
- No correlations between pH, uremia, hydration status and MARD
