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

Self-Blood Pressure Monitoring in an Urban, Ethnically Diverse Population: A Randomized Clinical Trial Utilizing the Electronic Health Record
Background —Hypertension is a leading risk factor for cardiovascular disease . Although control rates have improved over time , racial/ethnic disparities in hypertension control persist . Self-blood pressure monitoring , by itself , has been shown to be an effective tool in predominantly white population s , but less studied in minority , urban communities . These types of minimally intensive approaches are important to test in all population s , especially those experiencing related health disparities , for broad implementation with limited re sources . Methods and Results —The New York City Health Department in partnership with community clinic networks implemented a r and omized clinical trial ( n=900 , 450 per arm ) to investigate the effectiveness of self-blood pressure monitoring in medically underserved and largely black and Hispanic participants . Intervention participants received a home blood pressure monitor and training on use , whereas control participants received usual care . After 9 months , systolic blood pressure decreased ( intervention , 14.7 mm Hg ; control , 14.1 mm Hg ; P=0.70 ) . Similar results were observed when incorporating longitudinal data and calculating a mean slope over time . Control was achieved in 38.9 % of intervention and 39.1 % of control participants at the end of follow-up ; the time-to-event experience of achieving blood pressure control in the intervention versus control groups were not different from each other ( logrank P value = 0.91 ) . Conclusions —Self-blood pressure monitoring was not shown to improve control over usual care in this largely minority , urban population . The patient population in this study , which included a high proportion of Hispanics and uninsured persons , is understudied . Results indicate these groups may have additional meaningful barriers to achieving blood pressure control beyond access to the monitor itself .
