Diabetes self‐management education and its association with hospital admissions and premature mortality: A scoping review and meta‐analysis
Authors' conclusion
DSME may offer a survival benefit for adults with type 2 diabetes, but current evidence does not support an association with reduced hospitalisation.
Study context
- Population
- Adults with T2D; searches of CINAHL, MEDLINE and EMBASE (10 January 2024, checked September 2025), no restrictions on design, quality, location or sex42 studies
- Comparison
- Diabetes self-management education (DSME) vs no DSME
- Outcome
- Mortality and hospital admissions
Methodological detailsPRISMA extension for scoping reviews, meta-regression, 294 records from databases and 66 from manual searches

Pooled result
As reported in the abstract
- Mortality risk, pooled analysis restricted to studies with mortality as a primary outcome (≈45% reduction)
- RR 0.55, 95% CI 0.47-0.63, p < 0.0001
- Admission risk among DSME groups: non-significant reduction
- 9%
- Mortality reported as primary outcome significantly moderated the treatment effect (meta-regression; τ2 = 0; I2 = 0%; R2 = 100%)
- p = 0.0002
Further pooled results
Hospital admission risk
- Non-significant reduction in admission risk among DSME groups
- 9%
- Evidence on hospitalisation inconsistent, heterogeneous outcome definitions
Meta-regression of mortality effect: mortality reported as primary outcome as moderator
- Mortality as primary outcome significantly moderated treatment effect
- P = 0.0002
- Between-study heterogeneity
- τ2 = 0; I2 = 0%; R2 = 100%
