Introduction: A good injection technique is crucial to ensure that insulin is properly administered into the subcutaneous tissue and then released at the right time, to avoid some common complications such as lipodystrophies (LD). The objective of our study is to evaluate injection techniques in Moroccan diabetic patients.

Materials and methods: We conducted a prospective study including any diabetic insulin-treated patient for more than 6 months, followed up at the service between February 2015 and June 2017. Patients completed a questionnaire and were analyzed according to their injection techniques. Variables studied were the vectors used, injection techniques, the injection sites. The statistical analysis was performed by the SPSS software.

Results: During the period mentioned, 1000 insulin patients were included, with a sex ratio of 2F/1H. The average age was 42±20 years. The average age of diabetes was 9.6 years (from 6 months to 37 years). The average duration of insulin therapy was 5.7 years (6 months to 37 years). The types of diabetes were: type 2 diabetes in 60% of patients, type 1 diabetes in 38% of patients and 2% slow type 1 diabetes. The vector used was an insulin syringe in 92% of patients and insulin pens in 8% of patients. Only 12% used the antiseptic before the insulin injection. The injection fold was performed in 43% of patients and released in 15% of patients. Needle retention after injection was observed in 41% of cases. Rotation of injection sites was noted in 55% of patients. All patients reported reusing the needle and 97% used it more than four times.

Conclusion: Our study shows a number of gaps in knowledge of injection techniques, which points to the importance of regular verification of prior learning and regular reminder of key points of the injection technique at each consultation.
