Nutritional interventions and related efforts addressing undernutrition during rehabilitation after acquired brain...

Patients with an acquired brain injury (ABI) are at an increased risk of undernutrition due to the disease-related inflammation and other numerous symptoms that impact their nutrition. Unfortunately, recommendations related to nutritional interventions and related efforts vary. The objective of this scoping review is to map the body of literature on nutritional interventions and related efforts provided by health professionals, such as screening or assessments, addressing undernutrition in adults with a moderate to severe ABI during the subacute rehabilitation pathway.

The review follows the Joanna Briggs Institute methodology for scoping reviews. The librarian-assisted search strategy will be conducted in the bibliographical databases: MEDLINE (PubMed), Embase, CINAHL, Web of Science and OpenGrey. Indexed and grey literature in English, German or Scandinavian languages from January 2010 will be considered for inclusion. Two independent reviewers will conduct the iterative process of screening the identified literature, paper selection and data extraction. Disagreements will be resolved by discussion until a consensus is reached. A template will be used to guide the data extraction. This scoping review will include research articles, methodological papers and clinical guidelines reporting on nutritional interventions or related efforts to prevent or address undernutrition in adult patients (≥18 years) with moderate to severe ABI within the first year after admission to rehabilitation hospital. We will map all kinds of nutritional efforts provided by professionals in different settings within high-income countries, including interventions targeting relatives.

This review will involve the collection and analysis of secondary sources that have been published and/or are publicly available. Therefore, ethics approval is not required. The results will be published in an international peer-reviewed journal, presented at scientific conferences and disseminated through digital science communication platforms.
