Mapping research evidence on implementation of the WHO 'best buys' and other interventions for the prevention and control of non-communicable diseases in sub-Saharan Africa: a scoping review protocol.

Background: The rising burden of non-communicable diseases (NCDs) is a global health concern. To reduce the burden of morbidity, mortality and disability due to NCDs, the World Health Organization (WHO) developed 'best buys' and other interventions for the prevention and control of NCDs by member countries. However, their extent of implementation especially in sub-Saharan African countries (SSA) is not known.
