Psychosocial barriers to healthcare use among individuals with diabetes mellitus: A systematic review

PURPOSE: To conduct a systematic review regarding psychosocial barriers to healthcare use in individuals with diabetes mellitus, using a well-established model of health-service use as a theoretical framework. METHODS: We used database-specific controlled vocabularies and additional free text terms, and conducted searches via MEDLINE, EMBASE, PsycINFO, CINAHL, Web of Science, OVID Journals. Included studies were rated according to the UK National Institute for Health and Care Excellence (NICE) criteria. A narrative data synthesis was conducted, using the Andersen model and developing categories from the included studies. PRINCIPAL RESULTS: In total, 2923 studies were identified, and 15 finally included. We identified barriers according to the main categories “population characteristics”, “norms and values”, and “healthcare services” on a contextual and individual level, as well as “health status”. Frequently reported barriers were “socioeconomic status”, and “physician characteristics”. Ethnic minorities were frequently analysed and may have specific barriers, e.g. “cultural beliefs” and “language". MAJOR CONCLUSIONS: We identified a broad range of barriers to healthcare use in individuals with diabetes mellitus. However, the number of studies is low. Further research is needed to analyse barriers in more detail considering special subgroups
