Budget impact analysis of insulin therapies and associated delivery systems.

Purpose: A budget impact analysis of insulin therapies and associated delivery systems is presented.

Methods: Based on inputted procurement totals, per-item costs (based on 2011 average wholesale price), insulin distribution system (floor stock or individual patient supply), waste, and treatment protocols for a specified time frame, the budget impact model approximated the number of patients treated with subcutaneous insulin, costs, utilization, waste, and injection mechanism (pen safety needle or syringe) costs. To calculate net changes, results of one-year 3-mL vial use were subtracted from one-year 10-mL vial or 3-mL pen use.
