Reason for refusal of insulin therapy among type 2 diabetes mellitus patients in primary care clinic in Bangalore

BACKGROUND: Early initiation of insulin therapy and thereby the better control of blood sugar levels has shown reduction in complications. Although insulin therapy has been demonstrated to be efficacious, its initiation is often delayed due to multiple factors including the refusal of insulin therapy by the patients. This study aims to explore the reasons for the refusal of insulin therapy in a resource-constrained primary care setting in an urban slum in India. MATERIALS AND METHODS: We included 148 patients who required insulin therapy but refused. A semi-structured questionnaire was administered by a primary care physician. Chi-square test was done to test the association between demographic factors and the reasons for refusal. P < 0.05 was considered as significant. RESULTS: The mean age of the patients was 49.53 (SD+/-9.8) years. Majority (40.5%) of the patients had diabetes for 6-10 years, and most of them were living with their families (89.9%) and 77% of them were dependent on their family for their financial and physical needs. Financial constraint was the most common reason for reason (74.3%) followed by afraid of pain (68.9%) and fear of dependency (57.4). Gender, occupation, and duration of diabetes and witnessing insulin administration were significantly associated with stigma related to insulin therapy. CONCLUSION: Financial constraint is one of the key factors as patients have to buy insulin out of pocket and are not covered by insurance. Government initiatives to reduce and monitor the cost of the insulin would be of great benefit to the patients in this setting.
