Evaluation of flash glucose monitoring after long-term use: A pediatric survey

Published:September 26, 2018DOI:https://doi.org/10.1016/j.pcd.2018.08.004

      Highlights

      • Long-term FreeStyle Libre® sensor use was studied in a 347 strong pediatric cohort.
      • Patients/parents mainly chose flash glucose monitoring for reasons of comfort.
      • Roughly two in three patients faced difficulties with the device.
      • About two in three were satisfied overall.
      • One third of patients improved their glycemic control.

      Abstract

      Aims

      To understand the opinions of children with type 1 diabetes about their everyday use of flash glucose monitoring. (FGM).

      Methods

      Children with type 1 diabetes using the FreeStyle Libre® FGM system and/or their parents were surveyed in several French medical centers between December 2016 and June 2017, regardless of their treatment regimen and metabolic control.

      Results

      Of the 347 patients recruited, 79.5% had been using the sensor for more than three months (average usage time: 285 days). The main reported motivations for initiating this type of monitoring were to avoid finger prick pain (for 85.9% of patients) and to allow parents to check nocturnal glucose levels (60.8%). Two-thirds of respondents experienced difficulties, mainly the sensor falling off (47.6%), measurement discrepancies (25.1%) and cutaneous reactions (22.2%); 89.5% changed their habits: 70.6% took more scans, 37.2% corrected their hyperglycemia more promptly, and 37.5% used trends to adjust their insulin dosage. About one-third of the study group (35.1%) experienced lower HbA1c levels, and two thirds (67.1%) were satisfied with the device.

      Conclusions

      Our results show that FGM is a widely accepted option for self-monitoring diabetes, but that specific training is required to improve its use for insulin dosage adjustment and metabolic results.
