An observational study on usage of insulin and self-injection practises among patients with diabetes attending to Diabetic Centre and Medical outpatient clinics of a tertiary care hospital of Northern Sri Lanka
Abstract Background: Prevalence of diabetes increasing world-wide particularly in low income countries. Management of diabetes sometimes requires insulin injection due to various reasons. Proper usage of insulin and injection techniques are important for diabetes control among who requires insulin. This study was aimed to assess current insulin practices and associated complications.Methods and material: This was a cross sectional study conducted among diabetes patients attended all medical clinics and Diabetic Centre in Jaffna teaching Hospital which is the only tertiary hospital in the Northern Sri Lanka in May 2020.Insulin practices retrieved by using interviewer administered questionnaire. Data was analyses by using SPSS 26.Results: Out of 360 patients 64.2% were female and mean age was 58.19 (12-89).Majority (61.9%) of them belongs to low income category and most (73.3%) of them using insulin more than 1 year. Main reason for the insulin initiation was oral hypoglycaemic failure (81.7%) and majority of them (80.0%) were using twice daily premixed insulin regime followed by daily basal insulin (11.4%) and basal bolus insulin (5.6%) regime. Most of the participants (81.4%) reported they do cleaning of the injection site before injection and 89.7% usually rotate the injection site. Approximately half of them (50.8%) inject themselves and majority use syringes (91.4%). Common injection site complications reported were skin changes (25%), followed by 15.3% persistent swelling (15.3%) and thinning of skin(7.8%). Angle of injection (P-0.039) and insulin regime (P<0.001) showed statistically significant association with skin changes.High proportion of participants 68.6% (95%CI: 63.7%-73.2%) experienced hypoglycaemia, using syringes 2.21 times (95%CI-1.05-4.64) more risk of compare to pen users and missing meals 2.22 times more risk of hypoglycaemic events (95%CI: 1.18-4.17). Majority of them reported reusing the needles for injection (83.6%) and 35% were disposing needle into common garbage pin.Conclusion: This study revealed significant gaps in current insulin practices from expected norm and hypoglycaemic events alarmingly high among participants. Exploring Continuous Glucose Monitoring Devices or flash monitoring can be a mitigation strategy and urgent attention from health professionals needed to improve the safe insulin practices.
