Insulin injection training will lead to improved glucose control and greater satisfaction with treatment. The purpose of this study was to determine the impact of insulin injection re-education on injection errors and blood glucose control in the patients with type 2 diabetes.

This semi-experimental study was performed on 108 patients with type 2 diabetes referred to Yazd Diabetes Center using simple random sampling. The data collection tool was a researcher-made questionnaire that was completed for the patients before and three months after the intervention. The educational content was sent to the participants in the form of a five-minute video and via mobile phone. Data were analyzed using Pair t-test in SPSS 16.

The mean age of the participants was 61.44 ±8.94 years. The appropriate injection before and after the intervention in terms of the frequency of reused needle (20.4% vs 39.7% , p=0.013), keep pressing (47.2% vs 70.5%, p=0.001), size of the injection area (52.8% vs 75.3%, p=0.001), injection rotation (28.7% vs 37.2%, p=0.02 ) and insulin injection time (65.7%% vs 75.6%, p=0.04), showed a significant increase.

Insulin injection re-education can lead to reducing patients' errors related to the injection. Therefore, teaching patients at regular intervals can improve their performance in the field of insulin injection and improve the quality of treatment.
