Abstract
We conducted a randomized controlled trial using mobile health technology in an ethnically diverse sample of 137 patients with complicated diabetes Patients in the intervention group n 72 were trained to measure their blood glucose with a sensor which transmitted the readings to a mobile phone via a Bluetooth wireless link Clinicians were then able to examine and respond to the readings which were viewed with a web based application Patients in the control arm of the study n 65 did not transmit their readings and received care with their usual doctor in the outpatient and or primary care setting The mean follow up period was 9 months in each group The default rate was higher in the patients in the intervention arm due to technical problems In an intention to treat analysis there were no differences in HbA 1c between the intervention and control groups In a sub group analysis of the patients who completed the study the telemonitoring group had a lower HbA 1c than those in the control group 7 76 and 8 40 respectively P 0 06
