Telemonitoring based service redesign for the management of uncontrolled hypertension: multicentre randomised controlled trial
Objective To determine if an intervention consisting of telemonitoring and supervision by usual primary care clinicians of home self measured blood pressure and optional patient decision support leads to clinical ly important reductions in daytime systolic and diastolic ambulatory blood pressure in patients with uncontrolled blood pressure . Design Multicentre r and omised controlled trial . Setting 20 primary care practice s in south east Scotl and . Participants 401 people aged 29 - 95 years with uncontrolled blood pressure ( mean daytime ambulatory measurement ≥135/85 mm Hg but ≤210/135 mm Hg ) . Intervention Self measurement and transmission of blood pressure readings to a secure website for review by the attending nurse or doctor and participant , with optional automated patient decision support by text or email for six months . Main outcome measures Blinded assessment of mean daytime systolic ambulatory blood pressure six months after r and omisation . Results 200 participants were r and omised to the intervention and 201 to usual care ; primary outcome data were available for 90 % of participants ( 182 and 177 , respectively ) . The mean difference in daytime systolic ambulatory blood pressure adjusted for baseline and minimisation factors between intervention and usual care was 4.3 mm Hg ( 95 % confidence interval 2.0 to 6.5 ; P=0.0002 ) and for daytime diastolic ambulatory blood pressure was 2.3 mm Hg ( 0.9 to 3.6 ; P=0.001 ) , with higher values in the usual care group . The intervention was associated with a mean increase of one general practitioner ( 95 % confidence interval 0.5 to 1.6 ; P=0.0002 ) and 0.6 ( 0.1 to 1.0 ; P=0.01 ) practice nurse consultations during the course of the study . Conclusions Supported self monitoring by telemonitoring is an effective method for achieving clinical ly important reductions in blood pressure in patients with uncontrolled hypertension in primary care setting s. However , it was associated with increase in use of National Health Service re sources . Further research is required to determine if the reduction in blood pressure is maintained in the longer term and if the intervention is cost effective .
