The Effectiveness of Home Blood Pressure on 24-Hour Blood Pressure Control: A Randomized Controlled Trial

BACKGROUND Home blood pressure monitoring (HBPM) is cited as an effective approach for improving blood pressure control. The objective of this study was to determine the effectiveness of HBPM combined with a health education session in reducing blood pressure and improving medication adherence among adults with hypertension. METHODS Two hundred thirteen participants were enrolled in a 3-month study and randomized to receive HBPM or usual care. Participants were also randomized to receive an educational session delivered using a pamphlet or a computer-based program. Topics of the educational session included preventing hypertension, managing weight, staying active, and cutting down on salt and fat. RESULTS At the 3-month follow-up, there was a reduction in ambulatory blood pressure among the HBPM group. However, the differences found within the HBPM group were no greater than those found among the control group. We did not detect a statistically significant difference in adherence to medication when comparing the HBPM to the usual care group. CONCLUSIONS HBPM and educational session did not lower blood pressure or improve medication adherence in our sample. A greater effect may have been seen if coupled with an enhanced educational intervention and if blood pressure measures were shared with the provided. The findings of this study provide useful insights for future HBPM studies.
