About nutritionDay

What is nutritionDay?

nutritionDay is a global initiative that aims to improve nutritional care in healthcare settings and raise awareness of disease-related malnutrition. Each year in November, nutritionDay is conducted as a 1-day, cross-sectional audit (nDay) and has become one of the largest international databases of hospitalized patients and nursing homes residents.


Data collection at nDay

On a single, specified day (nDay), hospital wards, ICUs, primary care units, and nursing homes around the world collect anonymized data and upload them to the nutritionDay database using a simple, standardized, and multilingual data collection system.Data collection is performed by means of standardized questionnaires. Unit staff provide information on unit structure and organization, patients’ medical history, diagnoses, treatments, and outcomes. Patients complete a short questionnaire covering nutritional habits, food intake, recent weight loss, mobility, self perceived health status.
