Summary

Multiple daily insulin injections using a pen-injector showed similar glycemic control but reduced anxiety compared to conventional syringe methods. Patients reported improved self-concept and less external locus of control with the pen-injector.

Area of Science:

  • Endocrinology
  • Psychology

Background:

  • Diabetes management often involves complex insulin regimens.
  • Patient psychosocial well-being is crucial for treatment adherence and quality of life.
  • Insulin pen-injectors offer an alternative delivery method to traditional syringes.

Purpose of the Study:

  • To compare the efficacy and psychosocial effects of multiple daily insulin injections via pen-injector versus conventional syringe methods.
  • To assess glycemic control (HbA1) and psychological outcomes, including anxiety and self-concept, in adult diabetic patients.

Main Methods:

  • A randomized crossover study involving 16 adult diabetic patients over two 6-month periods.
  • Patients were treated with either a pen-injector regimen (three preprandial, one bedtime injection) or a twice-daily regimen (short- and intermediate-acting insulin).

  • Psychosocial effects were measured using state anxiety, self-concept, and locus of control scales.

    • Main Results:

    • No significant difference in HbA1 levels was observed between the pen-injector and conventional syringe regimens (8.2% vs 7.6%).
    • The pen-injector regimen was associated with significantly lower state anxiety (p < 0.05) and a trend towards better self-concept and less external locus of control.
    • Subgroup analysis revealed that patients with lower trait anxiety experienced less state anxiety with the pen-injector, while those with higher trait anxiety showed improved self-concept.

    Conclusions:

    • Insulin pen-injectors provide comparable glycemic control to conventional syringe methods in adult diabetic patients.
    • Pen-injector use is associated with significant reductions in state anxiety and positive psychosocial effects, including improved self-concept.
    • The pen-injector regimen is a viable and potentially beneficial alternative for managing diabetes, particularly for patients experiencing anxiety.
