Background: This study aimed to assess whether a structured home blood pressure monitoring (HBPM) education program can improve blood pressure control in patients.
Methods: A cluster randomised controlled trial in which half of 240 patients in the intervention group received an education program focused on using HBPM machines at home, while the other half had the usual care. The primary endpoints were mean systolic blood pressure and diastolic blood pressure.
Results: Systolic blood pressure dropped 1.88 mmHg (p=0.372) and diastolic blood pressure significantly dropped 3.84 mmHg (p=0.004) in intervention group at 3 months. At 6 months, systolic blood pressure and diastolic blood pressure were still on a decreasing trend, but there was no significant difference in blood pressure changes between the two groups.
Discussion: The structured HBPM education program has the potential to improve patient blood pressure control at short term, but such effect appears tailing off at medium terms. Additional components may be needed to maximise and sustain the benefit of HBPM.
