Background. The Dutch guideline Eating Disorders defines admission criteria for children with anorexia nervosa (AN) in need for medical stabilization and advices close monitoring to detect refeeding syndrome (RFS) in an early stage. Methods. Admission criteria, recommendations at admission, and during first week of hospitalization were evaluated in accordance to the guideline. RFS was defined as decreased electrolyte concentrations and/or clinical features. Results. 22 patients were included with a total of 50 admissions. We observed that 62% of the admitted patients met one of the admission criteria, 190/300 (63%) recommended admission examinations were performed. During admission adherence decreased, in particular daily weighing and physical examination (12% and 6%, respectively). The guideline was not fully followed in any of the patients. None of the hospitalized patients met the RFS criteria. Conclusion. Guideline adherence was moderate and can be improved by a few adaptations, which may limit unnecessary laboratory testing.
