Completion of diabetes self-management education (DSME) programs is widely encouraged in type 2 diabetes, yet the extent to which full versus partial participation influences patient-reported outcomes remains unclear. A scoping review published in Diabetic Medicine evaluated the impact of DSME completion on self-care behaviors, quality of life (QOL), and diabetes-related outcomes.

The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension guidelines for scoping reviews and included studies identified from CINAHL, MEDLINE, and EMBASE databases. A total of 24 studies met the inclusion criteria, focusing on comparisons between full DSME completion (100%), partial completion (1%-99%), and no participation. Studies using intention-to-treat analyses or lacking control groups were excluded to isolate the effect of program completion.

The findings showed that full DSME completion was associated with improvements in self-management skills and QOL over a 3-6 month period. Gains were more pronounced in self-care behaviors and mental health-related QOL, while improvements in medication adherence and physical health outcomes were less consistent. No studies reported outcomes associated with partial DSME completion.

These findings indicate that full engagement in DSME is associated with short-term improvements in patient-reported outcomes, although evidence for sustained benefits and the role of partial participation remains limited.
