Optimal usage of continuous glucose monitoring (CGM) requires adequate preparation and training. Patients using a CGM system without special training often do not achieve their intended improvement of metabolic control. Some stop using the system due to disappointing results. For this reason a structured training programme called ‘SPECTRUM’ was developed in Germany to ensure a high-quality standard for the initiation of CGM systems. This programme is suitable for patients of all age groups and is applicable to all CGM systems and all forms of insulin therapy. Structured curricula (adults, parents of young children, adolescents) were developed enabling diabetes centres with less experience to offer comprehensive CGM training. Key requirements of SPECTRUM were (1) independent from manufactures and (2) product-neutrality enabling certification for reimbursement after formal evaluation within the framework of a large clinical trial. SPECTRUM was published in January 2016 in German and translations into other languages are planned.
