Experiences from a large-scale, interdisciplinary project with focus on nutrition of hospital patients, mainly concerning management and organisation, are reported. Three hospitals of varying size participated. The primary phase of the project demonstrated, that the main reasons for failure in the nutrition of individual patients were related to management. After a massive educational effort the goals for optimal nutrition were achieved to a markedly larger degree, and the main reasons for failures changed to the patient-related ones. Experiences from a number of experiments with the presentation of food were positive, and the food-culture in the departments was changed towards an increased use of snacks between meals. The expences in the kitchen increased markedly. We did not succeed in improving the medical doctors’ interest in the field of nutrition.
