Prevalence and incidence of mental health issues amongst adults with diabetes at risk of foot complications in the European Union: a systematic review protocol

Objective: The objective of this systematic review is to evaluate and synthesize the evidence to establish the prevalence and incidence of mental health issues in people at risk of diabetic foot ulceration living within the European Union. Introduction: Due to the large health and financial burden of diabetic foot ulceration, prevention is a key focus for clinicians and researchers. Current foot ulcer prevention strategies are directed at the assessment and management of physical pathologies and risk factors for diabetic foot ulceration. Psychological burden and risk factors are often overlooked. This review will determine the prevalence and incidence of mental health issues among adults with diabetes mellitus who are at risk of foot ulceration. The review will focus on European Union countries. Inclusion criteria: Studies considered for inclusion will report on adults with a formal diagnosis of either type 1 or type 2 diabetes mellitus, who are at risk of foot ulceration and mental health issues. Studies will have been completed in the European Union. Methods: A search of MEDLINE, CINAHL, AMED, Embase, Cochrane CENTRAL, and PsycINFO will be conducted for studies published in or translatable into English. Unpublished and gray literature will be searched. Studies will be selected against the review inclusion/exclusion criteria, and selected studies will be critically appraised, with data extraction and synthesis completed using the relevant JBI systematic review tools.
