Basic Structure of the Adult Version of SPECTRUM.

Module 0	Introduction Module 0 offers the participant a solid knowledge of the basic principles of CGM so that they can make an informed decision whether or not to use a CGM system. An explanation is given of how a CGM system works, the advantages and disadvantages are discussed, an overview of available CGM systems is given, and the process for reimbursement of costs is explained. Module 0 can be used in a variety of settings (large or small groups or individual consultations).
Module 1	Basic principles of CGM The participants are told in detail about how CGM systems work. The characteristics of tissue glucose measurements are discussed comprehensively. Basic knowledge with respect to the precision of the CGM system, the alarm settings, and the calibration also is presented.
Module 2	CGM start Participants start working with their CGM system; they insert the first sensor and receive hints on how to make it safely through the first days of CGM use. Together with the trainer, sensible alarm settings are programmed and the calibration procedure is discussed.
Module 3	CGM display and alarms At the beginning of this module the participants exchange their first experiences with using the system in daily life. They should also reflect upon their own experiences with the system. The participants learn to analyze and correctly interpret the data displayed by the CGM system so that they can make informed decisions on the appropriate therapy.
Module 4	CGM analysis 1 The main aim of module 4 is to learn the methodology needed to evaluate the stored data. An overview analysis of the glucose trace over several days is carried out. An in-depth analysis of the individual days will then be performed. Finally, conclusions and therapy targets, which should be achieved by the next module, will be defined by the participants themselves.
Module 5	CGM analysis 2 The prime objective of module 5 is to practice the learnt methodology for the evaluation of CGM data. Again all of the data of each participant are evaluated (but not rated). By practicing together, the participants can gain confidence on how to deal with the “flood” of data and possible uncertainties can be reduced.
Module 6	CGM advanced training Problems that have occurred when changing the sensor (eg, where they should be applied, adhesion problems, skin reactions) are discussed retrospectively. The participants gather more information, for example CGM in conjunction with physical exercise, swimming, use in the sauna, on holiday or in hospital.
