Abstract
Aims
The purpose of this study was to evaluate adherence to insulin therapy in patients
with diabetes. The underlying factors affecting insulin injection omission among patients
with type 1 or 2 diabetes were also investigated.
Methods
This cross-sectional study has been conducted on 507 patients with diabetes. Adherence
to insulin therapy was measured by the 8-Item Moriskey Medication Adherence Scale
(MMS) and the autocompliance method. Furthermore, socio-demographic, disease and injection-related
barriers to insulin injection were assessed.
Results
Based on the Morisky Green test, 14.3% and 28.8% of patients with type 1 and 2 diabetes
respectively had low adherence to insulin therapy. However, almost all patients were
adherent according to the autocompliance method. Different factors showed a significant
association with insulin compliance in both groups.
Conclusions
The current study suggests acceptable adherence to insulin therapy among patients
with type 1, and poor adherence in patients with type 2, diabetes. Our findings regarding
barriers with significant effect on insulin adherence may be useful to identify patients
at risk for low compliance, and to guide the design of proper strategies to improve
adherence and the consequential clinical outcomes.
