Clinical Medicine Insights: Endocrinology and Diabetes

The prevalence of diabetes mellitus (DM) in the elderly population currently represents almost one-half of the overall diabetic population. Treatment of DM often requires a multidrug regimen that includes insulin therapy; however, due to concomitant comorbidities such as dementia, vision loss, neuropathies, poor mobility, and poor manual dexterity, elderly patients may be at increase risk for hypoglycemia and other dosing errors that are associated with insulin administration. Insulin pen devices have been shown to provide more reliable, accurate, and simplified dosing, and therefore may be a safer, easier, and more acceptable method of insulin delivery in the elderly population. This review will describe the various insulin pen devices available today, as well as discuss the potential advantages of these devices in the elderly population.
