INS and diabetes mellitus: This study demonstrates that resident physician management of type-2 diabetes in a hospital can be changed and improved by providing a convenient pocket insulin dosing guide. Specifically, the use of BBI for diabetes management increased by over two-fold, and glycemic control improved over the course of admission for BBI-managed patients compared to no improvement for patients managed with SSI. Additional work is needed to develop tools that will promote an even higher utilization of BBI for hospital diabetes management.
