Plain English Summary

Background and study aims
This project examines if the use of mobile phone communication between people with diabetes and their healthcare givers improves existing diabetes self-management programmes in Congo, Cambodia and the Philippines. Mobile phones will be given to people to enable them to call for support. They will receive messages and calls about behaviour change and results and reminders to appointments and taking of medication.

Who can participate?
People older than 18 years who are known to have (pre-)diabetes and who receive existing Diabetes Self-Management Education (DSME) in the participating study centres can participate. Diabetes education, also known as diabetes self-management training (DSMT) or diabetes self-management education (DSME), is defined as a collaborative process through which people with or at risk for diabetes gain the knowledge and skills needed to modify behavior and successfully self-manage the disease and its related conditions

What does the study involve?
The intervention involves the sending of Short Messages Services (SMS) to people with diabetes to support them in the self-management of their disease, on top of their routine care in the self-management programme. Sending a SMS intervention (the intervention group) will be compared with routine care only (the control group). All participants in the intervention group will receive SMS, but the content and frequency of the messages will be adjusted to the profile of the patient and of his diabetes, for instance the use of insulin or not.

What are the possible benefits and risks of participating?
The potential benefits for participating people in the intervention group are an increased capacity for self-managing their diabetes, increased quality of care and improved diabetes control. Participants in both groups will continue to receive their normal care and support in the pre-existing programme. The pre-existing programme will be analysed and where needed optimised, which will benefit all participants in the study. Other benefits for all participants are receiving a mobile phone for free and half-yearly determination of glycosated haemoglobin for free. The risks are similar to those of the usual care - such as the finger prick for blood tests - and risks related to the use of mobile phones, for instance the cost of making phone calls, the loss of the phone and the sharing of the phone with others.

Where is the study run from?
The study will take place in 3 countries, the Democratic Republic (DR) of Congo, Cambodia and the Philippines. There will be 480 participants in each country. In DR Congo, the participants will come from six health centres that are part of the diabetes care network (CS Esengo, CS Mokengeli, CS 2ème Rue, CS Lisanga, CS St Alphonse, CS Kinkenda). In Cambodia, they will come from four provinces (Takeo, BanteayMeanchey, KompongSpeu and Kompong Thom) and Phonm Penh. In the Philippines, participants will be identified by community health workers in Quezon City, Metro Manila, in the City of Batac, IlocosNorte and in Pagudpud, IlocosNorte.

When is study starting and how long is it expected to run for?
The recruitment of participants will be done in June and July 2012. The study will run until September 2014.

Who is funding the study?
This project is supported by a BRIDGES Grant from the International Diabetes Federation. BRIDGES, an International Diabetes Federation project, is supported by an educational grant from Lilly Diabetes.

Scientific title

Mobile Phone Diabetes Self-Management Support: a multi-country analysis of its implementation in existing Diabetes Self-Management Education Programmes in the Democratic Republic of Congo, Cambodia and the Philippines


Study hypothesis

The use of mobile phone communication, on top of an existing Diabetes Self-Management Education (DSME) strategy, can improve health outcomes, access to care and self-management for people with diabetes in those programmes, in Democratic Republic of Congo, Cambodia and the Philippines.

Please note that as of 19/10/2012, the target number of participants for this trial was updated from '1200 in the three countries in total: 400 in each country, of which 200 in the intervention and 200 in the control group' to '1320 in total: 480 in each country of which 240 in intervention and 240 in control group'
