Perception towards Insulin Therapy and Factors Related to Insulin Refusal among Insulin Naive Type 2 Diabetes Mellitus Patients in Primary Care Clinics PKD Lipis
Keywords:Insulin Refusal, Insulin Naive, Type 2 Diabetes Mellitus
Introduction: Insulin is one of the suggested treatments to prevent and reduce long-term diabetes complications. However, due to many factors such as socio-demographic factors, many Type 2 diabetes mellitus patients refuse this treatment. This study aimed to determine perception towards insulin among naive Type 2 diabetes mellitus patients, to calculate the prevalence of rejecting insulin therapy, and to find out factors related to the refusal.
Materials and methods: This cross-sectional study involved 188 insulin naive Type 2 diabetes mellitus patients attending five primary health clinics in Lipis district, Pahang from October to November 2017. A five-point Likert Scale was used to determine perception towards insulin therapy and the Chi-square test was used to assess the proportion of acceptance of the therapy. Simple and multiple logistic regressions were utilised to study the associated factor(s).
Results: Mean score of 60.5 ± 8.2 pointed towards a negative appraisal of insulin therapy. Embarrassment to inject in public (69.1%) and concern of frequent hypoglycaemia (52.7%) were the most common perception. Nearly half of the respondents (46.3%) refused insulin therapy upon suggestion. After adjusting the variables using multiple logistic regressions, only gender (Adjusted OR=0.20, 95% CI=0.10-0.40, p<0.001), educational level (Adjusted OR=0.17, 95% CI=0.06-0.50, p=0.001), age (Adjusted OR=1.04, 95% CI=1.01-1.08, p=0.012) and glycated haemoglobin level (Adjusted OR=1.33, 95% CI=1.07-1.67, p=0.013) remained significant.
Conclusion: In conclusion, insulin refusal among insulin naive patients was common in Lipis with an overall negative perception towards therapy. By tailoring strategies according to the patient’s factors such as gender, educational level, age, and glycated haemoglobin level, the insulin refusal rate might decrease in the future.
