Intelligent and Educational System for Gestational Diabetes Management

This study aims to evaluate the safety and usability of a telemedicine system which includes intelligent tools for blood glucose analysis and supporting routine clinical monitoring carried out by nurses and endocrinologists. Type of study: Prospective, controlled, randomized (2:1) Participants: pregnant women diagnosed with gestational diabetes according to the National Diabetes Data Group criteria between 14 and 34 weeks of gestation. Patients with suspected clinical diagnosis of type 1 or type 2 diabetes will be excluded. In addition to the signed acceptance to participate in the study, requirements are: * Availability of a desktop computer or laptop with an internet connection and USB port. * Sufficient knowledge of Catalan and/or Spanish * A mobile phone Objective: To technically evaluate the SineDie telemedicine system and also the users' degree of satisfaction. Methodology of the study: Once signed consent for participation the patient will be randomized either to continue regularly scheduled visits (33% chance) or to use the Telemedicine system (66% chance). The randomization will be done using a system of allocation based on random numbers. The SINEDiE system includes: * Educational Program * Automatical Evaluation of glucose data -immediately after each download (frequency not exceeding 72 hours) * Alerts in case of failure of receiving information at the scheduled time or in case of incompleteness. * Alerts for glucose values higher than desirable but which could be corrected by diet changes and / or exercise * Alerts for high glucose values which cannot be corrected with the previous mentioned changes. In this case an appointment for face-to-face visit would be made. All warnings are also reported as an email to the endocrinologist and nurse Variables: * Statistical analysis of data: blood glucose, standard deviation, number of preprandial values\> 90, the number of postprandial values of\> 140 messages and warnings * Analytical variables: HbA1c at the start and every 4 weeks * Complications of pregnancy and childbirth if any. * Neonatal Complications if any * Survey of satisfaction with telemedicine tool Expected duration of the study: 6 months Number of patients included 20 patients
