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 .

Impact of Patient–General Practitioner Short-Messages-Based Interaction on the Control of Hypertension in a Follow-up Service for Low-to-Medium Risk Hypertensive Patients: A Randomized Controlled Trial
The evaluation in real-life setting s of services for the follow-up and control of hypertensive patients is a complex intervention , which still needs analysis of the roles , tasks , and re sources involved in the basic items : patient , healthcare professional , and the interaction between the two . To evaluate the impact of patient-general practitioner ( GP ) short-messages-based interaction , isolated from other items , on the degree of hypertension control in the follow-up of medium-to-low-risk patients in primary care , a r and omized controlled trial has been performed : 38 GPs enrolled 285 hypertensive patients who recorded the results of self-blood-pressure ( BP ) monitoring , heart rate , and body weight , and completed an optional question naire in an identical manner over a six-month period . The telemedicine group ( TmG ) sent the data to a telemedicine-based system that enabled patient-GP interaction ; the control group ( CG ) recorded the data on paper and could only deliver it to their GP personally in the routine visits . In the TmG , the results were better , but not significantly so , for : 1 ) degree of hypertension control , in terms of the percentage of uncontrolled hypertensives at the final visit ( TmG versus CG : 31.7 % versus 35.6 % ; p = 0.47 ) ; 2 ) reduction in hypertension during follow-up , comparing measurements ( performed by a professional ) at the initial and final visits of systolic BP ( 15.5 versus 11.9 ; p = 0.13 ) and diastolic BP ( 9.6 versus 4.4 ; p = 0.40 ) ; and 3 ) adherence to the protocol within compliance levels of interest in a real-life follow-up service : Gt50 % ( 84.8 % versus 73.3 % ) and Gt25 % ( 92.4.8 % versus 75.4 % ) ( p = 0.053 ) . Other factors such as average values of self-measured systolic BP , diastolic BP and heart rate , acceptability of the protocol , and median number of consultations and hospital admissions were similar in both groups . Outcomes show that , taken alone , the patient-GP short-messages-based interaction has very little impact on the degree of hypertension control in patients with this profile . In complex interventions , to discriminate the impact of each of its components in isolation will enable us to design an efficient follow-up service , little dem and ing in terms of healthcare professional dedication , and optimized in other basic aspects
