Towards a standardized nutrition and dietetics terminology for clinical practice: An Austrian multicenter clinical documentation analysis based on the International Classification of Functioning, Disability and Health (ICF)-Dietetics. 
High quality, continuity and safe interdisciplinary healthcare is essential.  Nutrition and dietetics plays an important part within the interdisciplinary team in many health conditions.  In order to work more effectively as an interdisciplinary team, a common terminology is needed.  This study investigates which categories of the ICF-Dietetics are used in clinical dietetic care records in Austria and which are most relevant to shared language in different medical areas.  A national multicenter retrospective study was conducted to collect clinical dietetic care documentation reports.  The analysis included the "best fit" framework synthesis, and a mapping exercise using the ICF Linking Rules.  Medical diagnosis and intervention concepts were excluded from the mapping, since they are not supposed to be classified by the ICF.  From 100 dietetic records, 307 concepts from 1807 quotations were extracted.  Of these, 241 assessment, dietetics diagnosis, goal setting and evaluation concepts were linked to 153 ICF-Dietetics categories.  The majority (91.3%) could be mapped to a precise ICF-Dietetics category.  The highest number of ICF-Dietetics categories was found in the medical area of diabetes and metabolism and belonged to the ICF component Body Function, while very few categories were used from the component Participation and Environmental Factors.  The integration of the ICF-Dietetics in nutrition and dietetic care process is possible.  Moreover, it could be considered as a conceptual framework for interdisciplinary nutrition and dietetics care.  However, a successful implementation of the ICF-Dietetics in clinical practice requires a paradigm shift from medical diagnosis-focused health care to a holistic perspective of functioning with more attention on Participation and Environmental Factors.
