Real-world evaluation of the effects of counseling and education in diabetes management

Abstract

Background. Patient education has long been recognized as a component of effective diabetes management, but the impact of counseling and education (C/E) interventions on health care costs is not fully understood. Objectives. To identify the incidence and type of diabetes C/E received by type 2 diabetes patients and to evaluate associated economic and clinical outcomes. Methods. This retrospective cohort study used the Premier- Optum Continuum of Care database (2005-2009) to compare adult patients with type 2 diabetes receiving C/E to those not receiving C/E (control). The index date was the first C/E date or, in the control cohort, a randomly assigned date on which some care was delivered. Patients had at least 6 months' pre-index and 12 months' post-index continuous health plan coverage. Health care costs and glycemic levels were evaluated over 12 and 6 months, respectively, with adjustment for differences in baseline characteristics using propensity score matching (PSM). Results. Of 26,790 patients identified, 9.3% received at least one C/E intervention (mean age 53 years, 47% men) and 90.7% received no C/E (mean age 57 years, 54% men). Standard diabetes education was the most common form of C/E (73%). After PSM, C/E patients had some improvements in glycemic levels (among those with laboratory values available), without increased risk for hypoglycemia, and incurred $2,335 per-patient less in diabetes-related health care costs, although their total health care costs increased. Conclusions. Despite the low uptake of C/E services, C/E interventions may be associated with economic and clinical benefits at 12 months. Further analyses are needed to evaluate the long-term cost-effectiveness of such initiatives.
