In subgroup analysis , high strength evidence supported a lower BP with HBPT that lasted for 6 or 12 months and was accompanied with counselling support from study personnel .
HBPT can improve BP control in the hypertensive patients .

Effect of self-monitoring and medication self-titration on systolic blood pressure in hypertensive patients at high risk of cardiovascular disease: the TASMIN-SR randomized clinical trial.
IMPORTANCE Self-monitoring of blood pressure with self-titration of antihypertensives ( self-management ) results in lower blood pressure in patients with hypertension , but there are no data about patients in high-risk groups . OBJECTIVE To determine the effect of self-monitoring with self-titration of antihypertensive medication compared with usual care on systolic blood pressure among patients with cardiovascular disease , diabetes , or chronic kidney disease . DESIGN , SETTING , AND PATIENTS A primary care , unblinded , r and omized clinical trial involving 552 patients who were aged at least 35 years with a history of stroke , coronary heart disease , diabetes , or chronic kidney disease and with baseline blood pressure of at least 130/80 mm Hg being treated at 59 UK primary care practice s was conducted between March 2011 and January 2013 . INTERVENTIONS Self-monitoring of blood pressure combined with an individualized self-titration algorithm . During the study period , the office visit blood pressure measurement target was 130/80 mm Hg and the home measurement target was 120/75 mm Hg . Control patients received usual care consisting of seeing their health care clinician for routine blood pressure measurement and adjustment of medication if necessary . MAIN OUTCOMES AND MEASURES The primary outcome was the difference in systolic blood pressure between intervention and control groups at the 12-month office visit . RESULTS Primary outcome data were available from 450 patients ( 81 % ) . The mean baseline blood pressure was 143.1/80.5 mm Hg in the intervention group and 143.6/79.5 mm Hg in the control group . After 12 months , the mean blood pressure had decreased to 128.2/73.8 mm Hg in the intervention group and to 137.8/76.3 mm Hg in the control group , a difference of 9.2 mm Hg ( 95 % CI , 5.7 - 12.7 ) in systolic and 3.4 mm Hg ( 95 % CI , 1.8 - 5.0 ) in diastolic blood pressure following correction for baseline blood pressure . Multiple imputation for missing values gave similar results : the mean baseline was 143.5/80.2 mm Hg in the intervention group vs 144.2/79.9 mm Hg in the control group , and at 12 months , the mean was 128.6/73.6 mm Hg in the intervention group vs 138.2/76.4 mm Hg in the control group , with a difference of 8.8 mm Hg ( 95 % CI , 4.9 - 12.7 ) for systolic and 3.1 mm Hg ( 95 % CI , 0.7 - 5.5 ) for diastolic blood pressure between groups . These results were comparable in all subgroups , without excessive adverse events . CONCLUSIONS AND RELEVANCE Among patients with hypertension at high risk of cardiovascular disease , self-monitoring with self-titration of antihypertensive medication compared with usual care result ed in lower systolic blood pressure at 12 months .
