For those surrogate outcomes , low-strength evidence failed to show difference .
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 .
It may be more efficacious when a proactive additional support is provided during the intervention process
To summarise evidence about the effectiveness of home blood pressure telemonitoring ( HBPT )  and identify the key components of intervention .
Home blood pressure management and improved blood pressure control: results from a randomized controlled trial.
BACKGROUND To determine which of 3 interventions was most effective in improving  blood pressure ( BP ) control , we performed a 4-arm r and omized trial with 18-month follow-up at the primary care clinics at a Veterans Affairs Medical Center . METHODS Eligible patients were r and omized to either usual care or 1 of 3 telephone-based intervention groups : ( 1 ) nurse-administered behavioral management , ( 2 ) nurse- and physician-administered medication management , or ( 3 ) a combination of both . Of the 1551 eligible patients , 593 individuals were r and omized ; 48 % were African American . The intervention telephone calls were triggered based on home BP values transmitted via telemonitoring devices . Behavioral management involved promotion of health behaviors . Medication management involved adjustment of medications by a study physician and nurse based on hypertension treatment guidelines . RESULTS The primary outcome was change in BP control measured at 6-month intervals over 18 months . Both the behavioral management and medication management alone showed significant improvements at 12 months-12.8 % ( 95 % confidence interval [ CI ] , 1.6%-24.1 % ) and 12.5 % ( 95 % CI , 1.3%-23.6 % ) , respectively-but not at 18 months . In subgroup analyses , among those with poor baseline BP control , systolic BP decreased in the combined intervention group by 14.8 mm Hg ( 95 % CI , -21.8 to -7.8 mm Hg ) at 12 months and 8.0 mm Hg ( 95 % CI , -15.5 to -0.5 mm Hg ) at 18 months , relative to usual care . CONCLUSIONS Overall intervention effects were moderate , but among individuals with poor BP control at baseline , the effects were larger . This study indicates the importance of identifying individuals most likely to benefit from potentially re source intensive programs . TRIAL REGISTRATION clinical trials.gov Identifier : NCT00237692
