Home blood pressure monitoring for hypertension best combined with intensive support

Peer-Reviewed Publication


People who monitor their own blood pressure at home are most likely to see a benefit if they combine it with individually tailored intensive support, according to a new systematic literature review and meta-analysis published this week in PLOS Medicine by Richard McManus of the University of Oxford, UK, and colleagues.

Home blood pressure monitoring is currently recommended for people with high blood pressure so health professionals can make necessary adjustments to treatment. Previous research has shown that self-monitoring reduces clinic blood pressure by a small but statistically significant amount, but how best to implement it and for which patients it might be most useful remain unclear.

In this new study, researchers searched the existing medical literature for randomized trials that included self-monitoring of blood pressure in people with high blood pressure. They then used individual patient data from 25 studies, with up to 10,487 patients in total, to evaluate the effect of self-monitoring on blood pressure levels.

Overall, self-monitoring was associated with a clinic measurement of systolic blood pressure that was reduced by 3.2 mmHg (95% confidence interval [CI] -4.9 to -1.6) compared to usual care at 12 months. The effect, however, was strongly influenced by the intensity of professional support. This ranged from no significant effect on blood pressure with self-monitoring alone (1.0 mmHg reduction; 95% CI -3.3 to 1.2) to a significant blood pressure reduction (6.1 mmHg reduction; 95% CI -9.0 to -3.2) when self-monitoring was combined with additional support such as with education, lifestyle counseling, or medication adjustment managed by the patient themselves.

Self-monitoring was associated with greater blood pressure reductions in people on fewer antihypertensive medications and with higher systolic blood pressure before self-monitoring (up to 170 mmHg).

Lead author Richard McManus said: "Home self-monitoring has little effect on blood pressure control unless it's combined with individually tailored support delivered by either a nurse, physician or pharmacist. This can lead to important decreases in blood pressure and improved control with potential to reduce the risk of developing associated life-threatening conditions."

FDRH is part funded as Director of the National Institute for Health Research (NIHR) School for Primary Care Research (SPCR), Theme Leader of the NIHR Oxford Biomedical Research Centre (BRC), and Director of the NIHR Collaboration for Leadership in Applied Health Research and Care (CLAHRC) Oxford. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

Competing Interests:

I have read the journal's policy and the authors of this manuscript have the following competing interests: RJM has received research funding in terms of blood pressure monitors from Omron and Lloyds Healthcare; has received expenses and an honorarium from the Japanese Society of Hypertension and American Society of Nephrology. WJV is now employed by Microlife but was not at the time that the data contributed were collected. FDRH has in the past received limited free or subsidised BP measuring devices from Microlife and Omron to support hypertension research where there was no input from the companies to the design, funding, delivery, analysis, or interpretation of that research. SO is a consultant of Biotechmed Ltd. (provider of blood pressure telemonitoring services). SK has received research funding in terms of blood pressure monitors from Omron. HBB has received grant funding to Duke University from Sanofi, Johnson and Johnson, Takeda, WestMeadVaco, and Improved patient Outcome; has received an honorarium from Walgreens, Genentech, Sanofi; and has received funds for consulting for Sanofi. JPS received an MRC Strategic Skills Postdoctoral Fellowship (2013-2016) and now receives funding from the NIHR Oxford Collaborations for Leadership in Applied Health Research and Care. AB owns stocks in Insight Telehealth Systems LLC. MG received a research grant from the Heart and Stroke Foundation of Ontario prior to this work to conduct a study on self-monitoring of blood pressure, data from which are included in this meta-analysis. JG has held unrestricted investigator initiated grants from Pfizer and Boehringer-Ingelheim (BI) for unrelated research; is a member of the Lung Foundation Australia's (LFA) COPD-X guidelines committee. Pfizer, BI, or LFA did not have any role in my decision to participate in the work submitted by Tucker et al. IK has received travel grants and honoraria for speaking or participation at meetings from Sanofi-Genzyme and Shire concerning Fabry disease; has participated in clinical studies concerning diabetic nephropathy and hyperlipidemia sponsored by Bayer, Boehringer-Ingelheim, Merck Sharp and Dome and Pfizer.
