ObjectiveTo observe the application effects of puzzle mind mapping education method in patients using insulin injection device for the first time.

MethodsA total of 110 patients treated with insulin therapy for the first time from June 2019 to June 2020, and still needed self-injection after discharge were selected.The control group was hospitalized from June to December 2019, and the insulin injection skills were taught by the routine methods of our department.The observation group was hospitalized from January to June in 2020, and the insulin injection skills were taught by puzzle mind mapping.The standardization of insulin injection skills before 1 day of discharge, and injection-related complications after 3 months of treatment were compared between two groups.

ResultsBefore discharge, the results of the self-injection examination in two groups using insulin pen showed that the score in observation group was higher than that in control group(P < 0.05).The results of 20 specific items of insulin pen self-injection technology analysis showed that the differences of the accuracy rates of 14 items were statistically significant between two groups(P < 0.05 to P < 0.01), and which included correct positioning method, checking the injection site, right checking technique, disinfection range, insulin blending, blending method, pinch of skin, timing of the loose skin fold, residence time, enough the release timing, injection site rotation, use of insulin in store, unopened insulin storage and disposal of needles.After 3 months of discharge, the incidence rates of redness, swelling or induration at injection site, fat hyperplasia and pain in observation group were lower than those in control group(P < 0.05 to P < 0.01).

ConclusionsThe application of puzzle mind mapping education method in patients using insulin injection device for the first time can significantly standardize their injection skills, and reduce the complications caused by injection, which can be popularized and applied in other patient education.
