Continuous Subcutaneous Insulin Infusion Versus Multiple Daily Injections: Modeling predicted benefits in relationship to baseline A1c

With either continuous subcutaneous insulin infusion (CSII) or multiple daily insulin injection (MDII) therapy, the optimal meal insulin is a rapid-acting analog (lispro or aspart). To date, the efficacy of CSII versus MDII therapy has been evaluated in a limited number of randomized controlled trials in which rapid-acting analogs were used for both regimens. In this context, we recently conducted a pooled analysis (1) using raw trial data from three such studies undertaken in adults with type 1 diabetes (2–4). This analysis suggested that CSII is associated with better glycemic control, particularly in those patients with poor initial control. Indeed, the relative benefit of CSII over …
