Managing hypertension in urban underserved subjects using telemedicine--a clinical trial.
BACKGROUND We evaluated an Internet- and telephone-based telemedicine system for reducing blood pressure ( BP ) in underserved subjects with hypertension . METHODS A total of 241 patients with systolic BP ≥140 mm Hg were r and omized to usual care ( C ; n = 121 ) or telemedicine  ( T ; n = 120 ) . The T group reported BP , heart rate , weight , steps/day , and tobacco use twice weekly . The primary outcome was BP control at 6 months . RESULTS Average age was 59.6 years , average body mass index was 33.7 kg/m(2 ) , 79 % were female , 81 % were African American , 15 % were white , 53 % were at or below the federal poverty level , 18 % were smokers , and 32 % had diabetes . Six-month follow-up was achieved in 206 subjects ( C : 107 , T : 99 ) . Goal BP was achieved in 52.3 % in C and 54.5 % in T ( P = .43 ) . Systolic BP change ( C : -13.9 mm Hg , T : -18.2 ; P = .118 ) was similar in both groups . Subjects in the T group reported BP 7.7 ± 6.9 d/mo . Results were not affected by age , sex , ethnicity , education , or income . In nondiabetic T subjects , goal BP was achieved in 58.2 % compared with 45.2 % of diabetic T subjects ( P = .024 ) . Nondiabetic T subjects demonstrated a greater reduction in systolic BP ( T : -19 ± 20 mm Hg , C : -12 ± 19 mm Hg ; P = .037 ) . No difference in BP response between C and T was noted in patients with diabetes . CONCLUSION In hypertensive subjects , engagement in a system of care with or without telemedicine result ed in significant BP reduction . Telemedicine for nondiabetic patients result ed in a greater reduction in systolic BP compared with usual care . Telemedicine may be a useful tool for managing hypertension particularly among nondiabetic subjects
