The necessity of teaching diabetic patients the correct way of insulin administration : a clinical trial to improve glycemic control

الملخص EN

Background : it is important to achieve good glycemic control to avoid long-term diabetic complications.

It has been largely debated about the role of correct way of insulin administration to get the desired glycemic control.

Objective : to evaluate the effect of teaching diabetic patients who are on insulin therapy the correct way of injecting insulin and its effect on glycemic control.

Methods : A non-randomized clinical trial with 820 diabetic patients on insulin therapy on whom A1 c estimation was performed before and after three months of teaching them the right injection technique.

Results : Sixty seven patients (8.17 %) had A1 c 6.5 % before they were enrolled in the study while the majority (753 patents, 91.82 %) had A1 c 6.5 % and the last group showed the best benefit of teaching them the correct way of injection when compared with first group (P = 0.0001).

Also patient with age 20-40years showed the best results (P = 0.0001), while the poorest results were observed in those aged 40 years and above.

Conclusion : teaching patients the right injection technique is important to achieve good glycemic control in those who already had poor one.
