HYPERTENSION
An interactive web-based self-management system using the patient's mobile phone was tested and compared with usual care for the management of hypertension in a primary care setting. After 8 weeks, there was a significant increase in the proportion of participants with a BP of less than 140/90 mmHg in the intervention group compared with the control group. Almost half of the participants in the intervention group had a BP of less than 140/90 mmHg after 8 weeks and 12 months – compared with one-third at baseline. However, after 12 months, the difference between the intervention and the control group had decreased somewhat and was not statistically significant any longer.
