This study aimed to evaluate the effect of home telemonitoring on the control of high blood pressure in the Fangzhuang Community Health Center in Fengtai District, Beijing. A total of 110 hypertensive patients with uncontrolled high blood pressure were equally allocated to an intervention group and a control group randomly. The participants in the intervention group received home telemonitoring for blood pressure delivered by a team comprising a GP, a hypertension specialist, a general nurse and an information manager. The participants in the control group received the usual care. The levels of systolic and diabolic blood pressure of the participants were assessed on days 0 (baseline), 30, 90 and 180. On average, the intervention group had a greater reduction in blood pressure compared with the control by 6.6–8.0mmHg in systolic blood pressure and 0–3.0mmHg in diastolic blood pressure. Similarly, higher proportions of patients with normal blood pressure were achieved in the intervention group (63.6–71.2%) compared with the control (38.5–41.8%). The reduction in systolic blood pressure for the participants in the intervention group was positively correlated with the utilisation of the app (P<0.05). Home telemonitoring is effective in the control of high blood pressure.
