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 .
Mail education is as effective as in-class education in hypertensive Korean patients.
Many Korean American persons have hypertension , but competing life priorities often prevent them from attending health-promotion educational activities . Using principles of community-based participatory research , the authors conducted a prospect i ve clinical trial to determine the effectiveness of a mailed vs an in-class culturally tailored education intervention . A total of 380 hypertensive Korean American persons from the Baltimore/Washington area were assigned to a more intense in-class education group or a less intensive mail education group . Evaluation of postintervention blood pressure ( BP ) outcomes revealed that significant reductions in systolic BP ( 13.3 mm Hg and 16.1 mm Hg , respectively ) and diastolic BP ( 9.5 mm Hg and 10.9 mm Hg ) and increases in BP control rates ( 42.3 % and 54.3 % ) were achieved in both groups . No significant differences in BP outcomes between groups , however , were found . In conclusion , education by mail was an effective strategy for improving BP control and may be a viable approach for other immigrant groups if the education material s address their cultural needs
