Economic evaluation of home blood pressure monitoring with or without telephonic behavioral self-management in patients with hypertension.

Journal Article (Journal Article)

BACKGROUND: The Take Control of Your Blood Pressure trial evaluated the effect of a multicomponent telephonic behavioral lifestyle intervention, patient self-monitoring, and both interventions combined compared with usual care on reducing systolic blood pressure during 24 months. The combined intervention led to a significant reduction in systolic blood pressure compared with usual care alone. We examined direct and patient time costs associated with each intervention. METHODS: We conducted a prospective economic evaluation alongside a randomized controlled trial of 636 patients with hypertension participating in the study interventions. Medical costs were estimated using electronic data representing medical services delivered within the health system. Intervention-related costs were derived using information collected during the trial, administrative records, and published unit costs. RESULTS: During 24 months, patients incurred a mean of $6,965 (s.d., $22,054) in inpatient costs and $8,676 (s.d., $9,368) in outpatient costs, with no significant differences among the intervention groups. With base-case assumptions, intervention costs were estimated at $90 (s.d., $2) for home blood pressure monitoring, $345 (s.d., $64) for the behavioral intervention ($31 per telephone encounter), and $416 (s.d., $93) for the combined intervention. Patient time costs were estimated at $585 (s.d., $487) for home monitoring, $55 (s.d., $16) for the behavioral intervention, and $741 (s.d., $529) for the combined intervention. CONCLUSIONS: Our analysis demonstrated that the interventions are cost-additive to the health-care system in the short term and that patients' time costs are nontrivial.
