Up to now, nutritional counselling has been based primarily on the direct exchange of information between the customer and the service provider, based on expert knowledge. The use of sensor-supported IT could soon considerably improve the quality of this interaction. This is the aim of the DiDiER project (“Digitised services in the field of nutritional counselling for groups of people with increased health risks in the event of malnutrition”), which is funded by the German Federal Ministry of Education and Research (BMBF).
By making patient- and service-relevant information available digitally, the quality of advice provided by service providers in the field of nutritional counselling is to be considerably improved. The information is to be collected using mobile devices such as smartphones, tablets or sensors. By accessing this digital information, consultants can better prepare themselves for the individual patient as data is available earlier and without subjective distortion of perception. Patients, as well as consultants, benefit from access to external knowledge bases. The project partners are implementing this concept in two concrete cases of application in nutritional counselling: food intolerances/allergies and frailty in geriatric patients.
However, the use of these new technologies must also take into account the customer’s concern about data misuse. This is particularly true when comprehensive exercise and nutritional profiles are drawn up – even if this is done for the purpose of preventive health care, such as in the example of nutrition counselling for high-risk patients. In order to maintain this informational self-determination, the data therefore remain with the patient, who can allow his advisor to carry out evaluations of the data by means of so-called “Smart Services”. Instead of delivering the data to a central processing server in the “cloud”, processing it there and then returning the knowledge gained by algorithms to the customer, this process is to be reversed. The data remains with the customer, the personalized algorithms – the Smart Services – come to him and process the data without being able to pass it on, in his personal IT environment, especially developed for security, his “home cloud”. In this way, the customer retains full control over his or her data.
The project is coordinated by OFFIS (Oldenburg) together with DFKI (Saarbrücken), the University of Kaiserslautern, the Institute for Social Research and Social Economy (ISO, Saarbrücken), the University Hospital for Geriatrics at the University of Oldenburg, EUROKEY (Saarbrücken) and the German Allergy and Asthma Association (DAAB, Mönchengladbach).
