1033-P: Trends in U.S. Insulin Use for People with Diabetes: 2009-2017

Objective: Examine trends of insulin regimens, delivery devices and glucose monitoring among people with type 1 diabetes (T1D) or type 2 diabetes (T2D) in the U.S. from 2009-2017. Methods: The IBM® MarketScan® Commercial and Medicare databases were used to identify trends for insulin use over 9 years among people with T1D or T2D who filled a prescription for insulin in a calendar year. Total annual sample size ranged from 373,975 to 660,512. The analyses examined insulin regimen, method of delivery, and use of glucose monitoring systems separately for people with T1D or T2D. Generalized estimating equations were used to test whether trends were statistically significant. Results: For people with either T1D or T2D, use of short/rapid insulin only and use of analog insulins increased while premix insulin use decreased (all P
