Evaluation of the SPECTRUM training programme for real‐time continuous glucose monitoring: A real‐world multicentre prospective study in 120 adults with type 1 diabetes.

Aims: Comprehensive knowledge, specific skills and data‐analysis competences are prerequisites for the successful use of continuous glucose monitoring (CGM) systems. SPECTRUM is a structured training programme for real‐time CGM (rtCGM) consisting of a web‐based introduction and six group sessions of 90 min each. The 'CGM‐TRAIN study' evaluated the efficacy and acceptance of SPECTRUM and rtCGM systems among adults with insulin therapy. Methods: Participants (n = 120) were recruited from 10 German diabetes centres in which they were treated under usual care conditions. Outcome measures were rtCGM knowledge, practical skills, satisfaction with the training programme, satisfaction and acceptance of rtCGM system and glycaemic control. Data were collected at study entry, after training completion and at 6‐month follow‐up. Results: All participants were diagnosed with type 1 diabetes (56% women, mean age 42.4 ± 13.4 years, diabetes duration 21.6 ± 11.6 years), 110 participants completed the course. After training completion, rtCGM‐specific knowledge had improved by 43% (scale: 0–40 points) from 21.2 ± 7.6 to 30.4 ± 4.5 points; p < 0.001. The knowledge‐level persisted until follow‐up (29.4 ± 4.5). Participants were able to master nearly all the practical requirements of the technology. In addition, rtCGM was highly accepted, and participants were motivated to use their systems continuously. HbA1c improved slightly from 61 ± 14 mmol/mol (7.7 ± 1.3%) before training to 60 ± 14 mmol/mol (7.6 ± 1.3%) at follow‐up (p = 0.04). The training programme itself was favourably rated by participants. Conclusions: Under usual out‐patient daily care conditions, the training programme SPECTRUM improved knowledge and skills about rtCGM in adults with type 1 diabetes. This was associated with a reduced HbA1c, high satisfaction and acceptance of rtCGM (Clinical Trials Registry no.: DRKS00014380). [ABSTRACT FROM AUTHOR]
