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 .
Effectiveness of home-centered care through telemedicine applications for overweight and obese patients: a randomized controlled trial
OBJECTIVE : To determine if home-centered monitoring through telemedicine has an impact on clinical characteristics , metabolic profile and quality of life in overweight and obese patients . DESIGN : R and omized controlled trial , 6-month duration . SETTING : Tertiary care academic hospital . SUBJECTS : A total of 122 patients were eligible to participate as they met the inclusion criteria of increased body mass index ( BMI > 25 kg/m2 ) , age>18 and < 70 y and ability to operate electronic microdevices . INTERVENTIONS : All patients in the control group ( n=77 ) received st and ard hospital care .  Patients in the intervention group ( n=45 ) , additionally , measured three times a week , for 6 months , their blood pressure and body weight and transmitted them to an automated call center . These values were not shared with the patients ’ physician or dietician . MAIN OUTCOME MEASURES : Clinical ( body weight , BMI , blood pressure ) , laboratory ( fasting plasma glucose , triglycerides , HDL-cholesterol , total cholesterol ) and quality of life parameters ( SF-36 ® , Visual Analog Scale of European Quality -5 Dimensions , Obesity Assessment Survey ) . Data were analyzed in an intention-to-treat-way ( last observation carried forward ) . RESULTS : Drop-out rate was similar in the control and intervention groups : 12 vs 11 percent , respectively , P = NS . There were no significant differences at baseline between intervention and control groups in all main outcome parameters . There were significant decreases for patients in the intervention group in body weight ( from 101.6±22.4 to 89.2±14.7 kg , P=0.002 , P=0.05 vs controls at 6 months ) , total cholesterol ( from 247.6±42.0 to 220.7±42.6 mg/dl , P=0.002 , P=0.05 vs controls at 6 months ) and triglycerides ( from 148.4±35.0 to 122.3±31.4 mg/dl , P=0.001 , P=0.01 vs controls at 6 months ) . Intervention group patients made a total of 1997 phone contacts . The number of phone contacts was correlated positively with Social Functioning ( SF ) , Vitality ( VT ) and Mental Health ( MH ) scores of SF-36 ® at baseline ( r=0.48 , r=0.41 , r=0.41 , respectively , P=0.05 ) but not with weight loss . CONCLUSIONS : Home-centered , intense treatment through the use of telemedicine can be effective in improving short-term obesity outcomes
