 Within Latin America, there is a significant lack of data about the medical management and self-care for patients with non-communicable diseases NCDs, such as diabetes and hypertension. In an effort to improve availability of such data in the Latin American region, the World Health Organization WHO created and tailored a survey tool that has been used in various countries throughout Central and South America. Our own research team has extensive experience surveying clinic-based populations in Latin America regarding their chronic disease burden and the potential effectiveness of novel approaches to self-care support via mobile phones. The objective of the planned project is to gather baseline surveillance data for non-communicable diseases in urban and peri-urban Bolivian communities, using the WHO instrument as a foundation with modifications to reflect local public health priorities and the goal of developing mobile health services that improve self-management support.
