Abstract

Background
Addressing eating difficulties among older individuals with dementia living in nursing homes requires evidence-based interventions. However, to date, there is limited evidence of effective interventions designed to maintain and/or increase independent eating. In a field in which evidence is still lacking, a critical analysis of the state of research describing its main features can help identify methodological gaps that future studies should address. Hence, the aim of this study was to map the state of the research designed to maintain and/or promote independent eating in older individuals with dementia living in nursing homes.

Methods
A scoping review was performed by following the Preferred Reporting Items for Systematic Reviews and Meta-analyses. Reviews and conceptual analyses performed with different methodological approaches, published in indexed journals, and written in English were included. Keywords Were searched for in the MEDLINE, the Cumulative Index of Nursing and Allied Health, and in the Scopus databases to identify papers published up to 31 May 2018.

Results
17 reviews were included, assessing interventions’ effectiveness (n = 15) and providing conceptual frameworks for eating/mealtime difficulties (n = 2). Conceptual frameworks supporting interventions’ effectiveness have rarely been described in available studies. Moreover, interventions tested have been categorized according to non-homogeneous frameworks. Their effectiveness has been measured against (1) eating performance, (2) clinical outcomes, and (3) adverse event occurrence.

Conclusion
An increased use of conceptual frameworks in studies, as well as greater clarity in intervention categorization and outcomes, is necessary to enhance the reviews’ value in providing useful cumulative knowledge in this field. Interventions delivered should embody different components that integrate individual, social, cultural, and environmental factors, while when evaluating an intervention’s effectiveness, eating performance, clinical outcomes and adverse events should be considered. Together with more robust studies, involving clinicians could prove to be useful, as their knowledge of practice developed from direct experience can help develop innovative research questions.
