Relationships Between Cognitive Impairment and Self-Management in Older Adults With Type 2 Diabetes An Integrative Review

Abstract

Cognitive impairment is common in older adults with diabetes and is likely to negatively affect their daily diabetes self-management behaviors (DSMB). The primary aim of this integrative review was to summarize and synthesize the current state of knowledge about relationships between cognitive impairment and DSMB in older adults with type 2 diabetes. The review was guided by Whittemore and Knafl's 2005 framework, and study quality was evaluated using the Crowe Critical Appraisal Tool. Of 27 studies reviewed, 24 were quantitative, and three were qualitative. Heterogeneity was noted in study design, participant characteristics, and measures of cognitive function and DSMB. Overall, global cognitive impairment and executive function impairment related particularly to poor medication management and glucose self-monitoring. The findings supported the need for routine cognitive assessment of older adults with diabetes, but more longitudinal and interventional studies are needed to better define cognitive impairment-DSMB relationships.
