Description:Context
The health and economic burden of hypertension, a major risk factor for cardiovascular disease, is substantial. This systematic review evaluated the economic evidence of self-measured blood pressure (SMBP) monitoring interventions to control hypertension.
Evidence acquisition
The literature search from database inception to March 2015 identified 22 studies for inclusion with three types of interventions: SMBP used alone, SMBP with additional support, and SMBP within team-based care (TBC). Two formulae were used to convert reductions in systolic BP (SBP) to quality-adjusted life years (QALYs) to produce cost per QALY saved. All analyses were conducted in 2015, with estimates adjusted to 2014 U.S dollars.
Evidence synthesis
Median costs of intervention were $60 and $174 per person for SMBP alone and SMBP with additional support, respectively, and $732 per person per year for SMBP within TBC. SMBP alone and SMBP with additional support reduced healthcare cost per person per year from outpatient visits and medication (medians $148 and $3, respectively; median follow-up, 12–13 months). SMBP within TBC exhibited an increase in healthcare cost (median, $447 per person per year; median follow-up, 18 months). SMBP alone varied from cost saving to a maximum cost of $144,000 per QALY saved, with two studies reporting an increase in SBP. The two translated median costs per QALY saved were $2,800 and $4,000 for SMBP with additional support and $7,500 and $10,800 for SMBP within TBC.
Conclusions
SMBP monitoring interventions with additional support or within TBC are cost effective. Cost effectiveness of SMBP used alone could not be determined.
