Insulin injection practices among youngsters with diabetes in Tikur Anbesa Specialized Hospital, Ethiopia

The main aim of this study was to explore how participants were practicing insulin injections and assess its association with the insulin related-outcomes.

A hospital-based cross-sectional study was conducted among 176 youngsters with diabetes in Tikur Anbesa Specialized Hospital, Ethiopia. The inclusion criterion was the use of insulin treatment for a minimum of one year. Data about insulin injection practices was derived from participants' report. Descriptive statistics was presented using frequency distributions and percentages for categorical variables while measure of central tendencies and dispersion for continuous variables. Chi-square test was employed to test for the association between compared variables.

Participants were asked on how frequent they practice the appropriate insulin injecting practices. Based on that, eliminating air bubbles from a syringe, lifting skin fold during an injection, inserting a needle deep enough in the subcutaneous tissue, inspecting injection sites and self-monitoring of blood glucose were frequently done practices in more than 80% of the participants. Besides, over half of the participants reported that they frequently practice; insulin vial inspection, physical exercise, inject 1-3 cm apart from previous site, and insert a needle at 45⁰. Regarding insulin storage, more than half of them store opened insulin in the refrigerator, though it is advisable to store it at room temperature. Appropriate injection site rotation was reported by nearly one-third of the participants. Questions such as; gentle re-suspension of cloudy insulin, adjust insulin dose when necessary and change insulin syringe at every injection were reported by very few of the participants. Coming to glycemic control of our study subjects, 83% of them had HgbA1C of above 7.5% (non-optimal) and 31% reported at least one episode of hypoglycemia. Non-optimal glycemic control was explained by poor injection site hygiene (p < 0.038) and infrequent inspection of injection sites (p < 0.049).

Compared to previous studies, this study came with higher proportion of participants who frequently practice the appropriate insulin injection practices. However, it is still important to educate patients on some crucial injecting practices.
