Community- and mHealth-Based Integrated Management of Diabetes in Primary Healthcare in Rwanda: The D²Rwanda Study

Background: In Rwanda, diabetes mellitus (DM) prevalence has been estimated between 3.0 - 3.5%. Several factors, including an increase in screening and diagnosis programmes, the urbanization of the population, and changes in lifestyle are likely to contribute to a sharp increase in the prevalence of DM in the next decade, posing a daunting challenge for the fragile health care systems in low- and middle-income countries (LMICs). At the same time, the level of knowledge and perceptions of DM among patients is inadequate. Patients with low health literacy levels are often unable to recognise the signs and symptoms of DM, and may access their health provider late, hence presenting with more complications.

Although the majority of the Rwandan population seek care at the health centres, the Rwandan primary health care is facing a shortage of human resources. A community health worker programme was introduced in Rwanda in 2007 covering mainly infectious diseases, maternal and child health, and family planning.

In response to the need for better management of non-communicable diseases (NCDs) at the community level, the Ministry of Health of Rwanda and its partners adopted a new strategy and initiated a Home-Based Care Practitioner (HBCP) programme. Approximately 100 cells, belonging to the catchment area of nine selected hospitals, participate in the first phase of the HBCP programme (a "cell" is a small administrative area under the larger areas called "districts"). Every cell has two HBCPs, who completed high school and received six months of technical vocational education and training organised by the Ministry of Health in collaboration with its partners.

There is growing evidence for the efficacy of interventions using mobile devices (mHealth) in LMICs, particularly in improving treatment adherence, appointment compliance, data gathering, and developing support networks for health workers. In Rwanda, there is an urgent call to using mHealth interventions for the prevention and management of NCDs. The present research project responds to this by developing an mHealth intervention integrated in the current primary health care system, in support of both the DM patients and their healthcare providers.

Randomisation: The unit of randomisation will be the cluster, defined by the cell. In each cell two HBCPs work. Under each district hospital, the cells participating in the HBCP programme will be randomised to receive intervention 1 or 2. The patients from each group will receive the same intervention. An equal number of cells, out of those not participating in the HBCP programme, will be randomly selected and assigned to the control group.
