Plain English Summary
Background & study aims
Diabetes is a lifelong condition where the amount of sugar in the blood is too high. The aim of this pilot study is to collect performance data on the masked FreeStyle Libre Flash Glucose Monitoring System with adults with type 1 or 2 diabetes on haemodialysis. FreeStyle Libre Flash Glucose Monitoring System is a device designed for people with diabetes to monitor their blood sugar.
Who can participate?
Patients aged 18 and over with type 1 or 2 diabetes on haemodialysis
What does the study involve?
Participants will wear a masked Sensor for up to 14 days. Participants will be requested to obtain four fingerprick BG readings per day whilst wearing the Sensor (using the built-in test strip port in the Reader). Participants will be asked to scan the Sensor with the Reader at the same time as each fingerprick BG test, and at regular intervals.
Participants will return to the clinic for Visit 2 where the Sensor will be removed and data uploaded.
What are the possible benefits & risks of participating?
There is no direct benefit to the participant by taking part in this study. The only risks associated with the study are capillary blood sample collection, these are small but could include pain, bruising, local infection and fainting. Data collected may be used to support future pivotal trial designs in this population.

FreeStyle Libre flash glucose monitoring system use in insulin-treated patients undergoing dialysis: a pilot study
Determining whether the performance of the FreeStyle Libre system is different when used by people with diabetes undergoing haemodialysis vs data previously collected on the non-dialysis diabetes population.

Patient information sheet
No participant information sheet available
Diabetes mellitus (type 1 or type 2)
Participants will wear a Masked FreeStyle Libre Glucose Monitoring Sensor for 14 days and perform four fingerprick readings per day for each day of sensor wear using the built-in test strip port. There is no follow-up period unless the participant experiences an adverse device effect.
Primary outcome measure
1. The accuracy of the system will be measured for the duration the subject is wearing the device (up to 14 days). Each blood glucose result recorded on the reader will be paired with the nearest Sensor glucose result.
2. The safety of the device in the diabetic population sub-group will be measured using the number and percentage of participants experiencing adverse events during the study from the point of consent until the end of the study.
