Achievement of Insulin Injection Training By Skin Model in Diabetes Patients

Purpose:

 Many diabetic patients often had problems about insulin injection as they were not correct technics, had not sterile technic and did not get full drug dose. This was a common problem in clinical practice. While teaching in clinics still lack the proper materials and more expensive. So the skin model was appropriate media for instruction it, which is made of rubber. The rubber material is readily available and cheaper in Thailand. Objectives was to compare the achievement between experiment group taught by using the model and comparative group taught without model.

Methods: Samples were diabetic patients with first prescribed an injection. They were both male and female, all age group, literacy and participated in the study. It was randomized, double blinded and comparative design. The patients were selected to be experiment group and comparative group by simple randomization and blinded methods. Data were collected before and after teaching at OPD medicine and family medicine. The evaluation were achievement scores that patients had self-assessment and observational scores were assessed the accuracy by a nurse. Reliability scores of questionnaires were 0.7 and 0.8 respectively.The p-value of statistical significant difference was 0.05.

Results:

 The majority of them were female and the average age of 51.53 years, chose injected by themselves (85.71%). The average achievement scores in the experimental group was more than the comparative group statistically significant, especially knowledge, understand, skills of injection and injecting confidence. Its result was similar in the observational scores. In each technic of injection analysis, the experimental group can inject for full dose better than comparative group statistically significant and found similarly in technics of grab a pen right consistency and technic of prevention of reverse drug flow. But both groups did not differ in other technics such as cleaning the skin before and after injection, corrected location, making a homogeneous drug, the corrected dose, injection down on the subcutaneous layer and save needle as a sterile technics to be reused.

Conclusion: Skin model for teaching of insulin injection helped the patients had better skills, understand and knowledge  as well as increased confidence to injecting. It is appropriate to apply this skin model as a media for teaching self-injection of diabetic patients.
