Nutrition support teams (NST) are hospital transverse nutrition care structures, recently established and developed in France. In continental Europe, their prevalence is 5–10 % . Nutritional assessment and care are their main actions. Education, clinical research and assessment of the practices are secondary aims of NST. Physicians, dieticians, nurses and pharmacists are the main participants. The weekly durations of work dedicated to NST are low, explaining the small number of followed patients and the limited types of actions. NST are generally integrated in another hospital division or service, and provide examinations for in or out hospitalized patients. Interventions concern internal medicine, neurology, oncology, intensive care units, with patients suffering from digestive, neurological or cancer diseases. NST financing generally comes from hospitals. NST generates benefits for patients in terms of morbidity, mortality and length of stay and consequently save money. Nutritional competence of NST participants and duration of action could be predictive of good results. As propositions, international definition of NST should be clarified, the number of NST could increase, with more numerous and educated staffs, and more time dedicated. A better quotation of nutritional interventions and a development of assessment of NST could be recommended.
