Study on the effect of education for insulin injection in diabetic patients with new simulation tools

Insulin is an essential therapy for treating diabetes, but many patients lack standard insulin injection skills.

We developed a standard training procedure based on a new simulation tool. Then we conducted a study to investigate the effect of this standard training on the ability of diabetic patients to inject themselves with insulin.

After follow-up, a total of 120 patients with diabetes mellitus were included. These patients needed insulin therapy depending on their condition and had not previously learned insulin injection. We randomly divided them into the intervention group (60 cases) and the control group (60 cases). The control group was trained on insulin injection before being discharged according to the traditional method, and the intervention group was trained based on an improved simulation tool. All participants were trained as individuals or groups. Finally, we evaluated the learning effects of both groups.

The time spent at the training stage in the intervention group was shorter than the control group. We found that after applying simulation devices to mimic operations, the learning time for patients was reduced.The first subcutaneous injection success rate was 73.33% in the intervention group, which was significantly higher than that in the control group by 46.67%. The score of the first subcutaneous injection and pre-discharge score in the test group was significantly higher than that of the control group. One month later, the score for injection skills in the 2 groups was higher than that before discharge, and the score in the trial group was still higher than that in the control group. The incidence of subcutaneous fat hyperplasia in the trial group was lower than that in the control group (3.3% vs 15%, P < .05). Moreover, the incidence of hypoglycemia (16.7% vs. 26.7%) was higher in the control group, but the difference was not statistically significant (P = .184).

After applying simulation tools plus operating video and guideline as the standard procedure to train diabetic patients on insulin injection, all patients had a good grasp of using the insulin injection technique. This education method is safe, efficient, and worth promoting worldly.
