Initial experience and evaluation of reusable insulin pen devices among patients with diabetes in emerging countries

Many individuals with type 2 diabetes in emerging countries are transitioning from vial-and-syringe insulin delivery to that of insulin pens (disposable or reusable). As with all insulin delivery methods, patient preferences and comfort are of utmost importance to optimize adherence to treatment. Patient-preferred characteristics for reusable insulin pens and barriers to appropriate injection, particularly in these regions, have not been widely reported in the clinical literature, highlighting a key information gap for clinicians considering these methods as part of a comprehensive diabetes management approach.
