In medical rehabilitation for alcohol addiction, nutritional therapy social services: benefits are anchored as an evidence-based therapy module (ETM) in an indication-specific rehabilitation therapy standard (RTS). Nutritional therapy standards, recommendations for the interprofessional integration of nutritional therapy and targeted training options for nutritional therapy specialists are missing. The aims of the research project are to develop a framework concept for nutritional therapy, taking into account networking in the interprofessional therapy concept for alcohol dependence, and to design supplementary practical recommendations and working materials for nutritional specialists. To this end, a systematic literature review of (interprofessional) approaches to nutritional therapy for alcohol dependence will be carried out. In the next step, a comprise qualitative (individual and focus group interviews with interprofessional treatment teams or rehabilitation patients (groups)) and a supplementary quantitative data collection (online short questionnaire) will be carried out. On this basis, recommendations will be derived in a Delphi process with the support of an interprofessional advisory board of experts. The nutritional therapy framework concept with recommendations for the synergetic implementation of nutritional therapy in the treatment concept as well as the resulting practical recommendations and working materials are published and contribute to quality assurance in medical rehabilitation.
