Impact of monthly A1C values obtained at home on glycemic control in patients with type 2 diabetes: A randomized clinical trial

Abstract

The purpose of this randomized controlled clinical trial was to determine whether an A1C value obtained at home by participants followed by a phone discussion of the result with a clinician would lead to 1) a more rapid and significant decrease in A1C, 2) more effective advancement of diabetes treatment, and 3) improvement in diabetes self-care behaviors. The study included 307 participants with type 2 diabetes, most of whom were of Latino origin. All study participants experienced a statistically significant reduction in mean A1C (control subjects 20.3%, P 5 0.04; intervention subjects 20.5%, P 5 0.0002), but there was a statistically significant difference in the number of people who achieved a reduction of $0.5% by 6 months, favoring the intervention (33.6 vs. 46.7%, P 5 0.05).
