Effect of insulin pen devices on the management of diabetes mellitus

摘要

The number of people with diabetes mellitus worldwide is expected to more than double from 171 million in 2000 to 366 million in 2030, based on demographic changes alone. Consequently, the estimated cost of diabetes care in the United States is expected to increase from $132 billion in 2002 to $156 billion (in 2002 dollars) by 2010 and $192 billion by 2020. Given the increasing prevalence of obesity and its significance as a risk factor for diabetes, the expected number of cases of diabetes and actual cost in future years could be even higher.
