Telemonitoring and self-management in the control of hypertension (TASMINH2): a randomised controlled trial
BACKGROUND Control of blood pressure is a key component of cardiovascular disease prevention , but is difficult to achieve and until recently has been the sole preserve of health professionals . This study assessed whether self-management by people with poorly controlled hypertension result ed in better blood pressure control compared with usual care . METHODS This r and omised controlled trial was undertaken in 24 general practice s in the UK . Patients aged 35 - 85 years were eligible for enrolment if they had blood pressure more than 140/90 mm Hg despite antihypertensive treatment and were willing to self-manage their hypertension . Participants were r and omly assigned in a 1:1 ratio to self-management , consisting of self-monitoring of blood pressure and self-titration of antihypertensive drugs , combined with telemonitoring of home blood pressure measurements or to usual care . R and omisation was done by use of a central web-based system and was stratified by general practice with minimisation for sex , baseline systolic blood pressure , and presence or absence of diabetes or chronic kidney disease . Neither participants nor investigators were masked to group assignment . The primary endpoint was change in mean systolic blood pressure between baseline and each follow-up point ( 6 months and 12 months ) . All r and omised patients who attended follow-up visits at 6 months and 12 months and had complete data for the primary outcome were included in the analysis , without imputation for missing data . This study is registered as an International St and ard R and omised Controlled Trial , number IS RCT N17585681 . FINDINGS 527 participants were r and omly assigned to self-management ( n=263 ) or control ( n=264 ) , of whom 480 ( 91 % ; self-management , n=234 ; control , n=246 ) were included in the primary analysis . Mean systolic blood pressure decreased by 12.9 mm Hg ( 95 % CI 10.4 - 15.5 ) from baseline to 6 months in the self-management group and by 9.2 mm Hg ( 6.7 - 11.8 ) in the control group ( difference between groups 3.7 mm Hg , 0.8 - 6.6 ; p=0.013 ) . From baseline to 12 months , systolic blood pressure decreased by 17.6 mm Hg ( 14.9 - 20.3 ) in the self-management group and by 12.2 mm Hg ( 9.5 - 14.9 ) in the control group ( difference between groups 5.4 mm Hg , 2.4 - 8.5 ; p=0.0004 ) . Frequency of most side-effects did not differ between groups , apart from leg swelling ( self-management , 74 patients [ 32 % ] ; control , 55 patients [ 22 % ] ; p=0.022 ) . INTERPRETATION Self-management of hypertension in combination with telemonitoring of  blood pressure measurements represents an important new addition to control of hypertension in primary care .
