Assessment of Insulin Injection Technique Among Diabetic Patients in Makkah Region in Saudi Arabia

Introduction: Diabetes mellitus (DM) is defined as a chronic metabolic disorder characterized by persistent high blood glucose. Proper insulin injection is indispensable to achieve adequate control of DM and prevent complications. Therefore, this study aims to assess the knowledge of DM patients about their insulin injection techniques. Materials and Methods: A questionnaire-based and cross-sectional study was carried out from January to March 2020 at three locations in Makkah, Saudi Arabia. The inclusion criteria of research subjects included patients diagnosed with type-1 or type-2 DM and using insulin pen injection. The questionnaire included demographic data including age, gender, nationality, educational level, and chronic disease as well as specific questions about insulin injection technique. Results: Four hundred and thirty-seven DM patients participated in the study. The most prevalent age group was between 20 and 60 years old (69.1%). The vast majority of patients were females (64.1%), Saudi nationals (92.9%), and residents of Makkah city (70%). There were roughly equal numbers of patients with type-1 and type-2 DM (47% and 53%, respectively). With regard to complications of DM, 19.5% of patients had previous acidosis, and 16.5% of patients were admitted to hospital for various complications. Injection-related complications were reported by almost half of the patients (49.9). The knowledge of insulin injection practices was examined among DM patients according to different variables. Only the frequency of administration exhibited a significant difference in the practices toward proper insulin injection technique (p = 0.049); patients who administered insulin injection three times daily had the best practices toward insulin injection when compared to other patients. Conclusions: Our study showed that the practices toward insulin use among the surveyed DM patients in Makkah region were not satisfactory. Poor insulin injection technique is an important modifiable risk factor for uncontrolled blood glucose levels. More awareness campaigns and better counseling initiatives are crucial to guarantee steady insulin levels among DM patients.
