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 .
A multimodal blood pressure control intervention in 3 healthcare systems.
OBJECTIVE To determine if a multimodal intervention composed of patient education , home blood pressure ( BP ) monitoring , BP measurement reporting to an interactive voice response ( IVR ) phone system , and clinical pharmacist follow-up improves BP control compared with usual care . STUDY DESIGN Prospect i ve study with patient enrollment , medication consultation and adjustment , remote BP monitoring , and follow-up at 6 months . METHODS This r and omized controlled trial was conducted at 3 healthcare systems in Denver , Colorado , including a large health maintenance organization , a Veterans Affairs medical center , and a county hospital . At each site , patients with uncontrolled BP were r and omized to the multimodal intervention vs usual care for 6 months , with the primary end point of BP reduction . RESULTS Of 338 patients r and omized , 283 ( 84 % ) completed the study , including 138 intervention patients and 145 usual care patients .  Baseline BP was higher in the intervention group vs the usual care group ( 150.5/89.4 vs 143.8/85.3 mm Hg ) . At 6 months , BPs were similar in the intervention group vs the usual care group ( 137.4 vs 136.7 mm Hg , P = .85 for systolic ; 82.9 vs 81.1 mm Hg , P = .14 for diastolic ) . However , BP reductions were greater in the intervention group vs the usual care group ( −13.1 vs −7.1 mm Hg , P = .006 for systolic ; −6.5 vs −4.2 mm Hg , P = .07 for diastolic ) . Adherence to medications was similar between the 2 groups , but intervention patients had a greater increase in medication regimen intensity . CONCLUSIONS A multimodal intervention of patient education , home BP monitoring , BP measurement reporting to an IVR system , and clinical pharmacist follow-up achieved greater reductions in BP compared with usual care
