Background
Diabetes is a chronic condition that can lead to devastating complications if not managed effectively. Individuals with elevated HbA1c are at higher risk of developing complications resulting in diabetes‐related hospital admissions, an additional pressure and expense for healthcare systems.
Aim
To systematically review evidence of the effectiveness of psychosocial interventions among individuals with elevated HbA1c, as indicated by hospital admissions.
Methods
Electronic databases (MEDLINE, PsychINFO, CINAHL, AMED, Embase and Scopus) were used to identify studies systematically. Studies were screened against eligibility criteria and included if they evaluated the effectiveness of a psychosocial intervention on diabetes‐related hospital admissions in individuals with elevated HbA1c. Risk of bias was assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies, and a narrative synthesis was conducted.
Results
Of 15 362 studies, five were included in the review. Psychosocial interventions were found to significantly reduce diabetes‐related hospital admissions in four of these studies and interventions involving psychotherapy in particular were found to reduce admissions. The methodological quality of studies ranged from weak to moderate, due to lack of blinding, weak study design and issues with withdrawals and drop‐outs.
Conclusions
Psychosocial interventions may reduce diabetes‐related hospital admissions in individuals with elevated HbA1c; however, due to variability in methodological rigour, the conclusion remains tentative. Further research targeting this group, particularly within the adult population, is recommended. (PROSPERO registration number: CRD42019133456).
