Tailored Case Management for Diabetes and Hypertension (TEACH-DM) in a community population: study design and baseline sample characteristics.
BACKGROUND: Despite recognition of the benefits associated with well-controlled diabetes and hypertension, control remains suboptimal. Effective interventions for these conditions have been studied within academic settings, but interventions targeting both conditions have rarely been tested in community settings. We describe the design and baseline results of a trial evaluating a behavioral intervention among community patients with poorly-controlled diabetes and comorbid hypertension. METHODS: Tailored Case Management for Diabetes and Hypertension (TEACH-DM) is a 24-month randomized, controlled trial evaluating a telephone-delivered behavioral intervention for diabetes and hypertension versus attention control. The study recruited from nine community practices. The nurse-administered intervention targets 3 areas: 1) cultivation of healthful behaviors for diabetes and hypertension control; 2) provision of fundamentals to support attainment of healthful behaviors; and 3) identification and correction of patient-specific barriers to adopting healthful behaviors. Hemoglobin A1c and blood pressure measured at 6, 12, and 24 months are co-primary outcomes. Secondary outcomes include self-efficacy, self-reported medication adherence, exercise, and cost-effectiveness. RESULTS: Of 377 randomized patients, 193 were allocated to the intervention and 184 to attention control. The cohort is balanced in terms of gender, race, education level, and income. The cohort's mean baseline hemoglobin A1c and blood pressure are above goal, and mean baseline body mass index falls in the obese range. Baseline self-reported non-adherence is high for diabetes and hypertension medications. Trial results are pending. CONCLUSIONS: If effective, the TEACH-DM intervention's telephone-based delivery strategy and nurse administration make it well-suited for rapid implementation and broad dissemination in community settings.
