Qualitative analysis of patient responses to the ABCD FreeStyle Libre audit questionnaire

Abstract

The Abbott FreeStyle Libre flash glucose monitoring system is a novel sensor-based, factory-calibrated device that allows individuals with diabetes to monitor their interstitial glucose levels, capture up to 8 hours of interstitial glucose data, and predict future changes in interstitial glucose by scanning a temporary implantable glucose sensor with a reader device or compatible mobile phone. The study aim was to determine whether use of a flash glucose monitoring system had an impact on quality of life and to explore why this was the case. Raw data were collected as part of a brief semi-structured interview supported by the ABCD FreeStyle Libre Follow-Up Visit Data Collection form. Data were collected pragmatically at outpatient clinic follow-up visits, and the first 40 patients to complete six months of continuous use were included in the study. Feedback on use of the device was overwhelmingly (although not unanimously) positive. A number of basic themes were identified independently by the investigators, which were then grouped into four organising themes: Contrast with capillary blood glucose monitoring; Impact on hypoglycaemia experience; Glycaemic control and complications; and Improved wellbeing and quality of life. These themes are analysed and illustrated in the article. Copyright © 2019 John Wiley & Sons.
