Do patients with diabetes use the insulin pen properly?

Aim: This study was conducted to evaluate the insulin pen application knowledge and skills of patients with diabetes.Methods: In our descriptive study, 200 patients with diabetes were asked to present the insulin pen injection technique on a mannequin and the steps of the pen injection implementation were noted on the data collection form as correct/incorrect by researchers.Results: More than 3 out of 4 (79.5%) of the participants were using the insulin pen or the cartridge after the expiry date, 70.5% were not rotating the injection site, and 63.0% were massaging the skin after injection. Injection sites complications were sig- nificantly more in those who were using the insulin pen or the cartridge after the expiry date, those who don’t know the proper length of the needle and the possible body injection sites, those who don’t rotate the injection sites, those who massage after injection, and those who don’t use a new needle at each injection (p<0.05).Conclusion: This study put into light some failures in the knowledge and skills of patients with diabetes regarding insulin pen use. Nurses should provide patients with diabetes an effective and repetitive training concerning insulin pen use.Keywords: Diabetes, insulin injection, insulin pen, patient knowledge
