Health transition in Africa: practical policy proposals for primary care.

Sub-Saharan Africa is undergoing health transition as increased globalization and accompanying urbanization are causing a double burden of communicable and noncommunicable diseases. Rates of communicable diseases such as HIV/AIDS, tuberculosis and malaria in Africa are the highest in the world. The impact of noncommunicable diseases is also increasing. For example, age-standardized mortality from cardiovascular disease may be up to three times higher in some African than in some European countries. As the entry point into the health service for most people, primary care plays a key role in delivering communicable disease prevention and care interventions. This role could be extended to focus on noncommunicable diseases as well, within the context of efforts to strengthen health systems by improving primary-care delivery. We put forward practical policy proposals to improve the primary-care response to the problems posed by health transition: (i) improving data on communicable and noncommunicable diseases; (ii) implementing a structured approach to the improved delivery of primary care; (iii) putting the spotlight on quality of clinical care; (iv) aligning the response to health transition with health system strengthening; and (v) capitalizing on a favourable global policy environment. Although these proposals are aimed at primary care in sub-Saharan Africa, they may well be relevant to other regions also facing the challenges of health transition. Implementing these proposals requires action by national and international alliances in mobilizing the necessary investments for improved health of people in developing countries in Africa undergoing health transition.

Research needs for an improved primary care response to chronic non-communicable diseases in Africa.

With non-communicable diseases (NCDs) projected to become leading causes of morbidity and mortality in developing countries, research is needed to improve the primary care response, especially in sub-Saharan Africa. This region has a particularly high double burden of communicable diseases and NCDs and the least resources for an effective response. There is a lack of good quality epidemiological data from diverse settings on chronic NCD burden in sub-Saharan Africa, and the approach to primary care of people with chronic NCDs is currently often unstructured. The main primary care research needs are therefore firstly, epidemiological research to document the burden of chronic NCDs, and secondly, health system research to deliver the structured, programmatic, public health approach that has been proposed for the primary care of people with chronic NCDs. Documentation of the burden and trends of chronic NCDs and associated risk factors in different settings and different population groups is needed to enable health system planning for an improved primary care response. Key research issues in implementing the programmatic framework for an improved primary care response are how to (i) integrate screening and prevention within health delivery; (ii) validate the use of standard diagnostic protocols for NCD case-finding among patients presenting to the local health facilities; (iii) improve the procurement and provision of standardised treatment and (iv) develop and implement a data collection system for standardised monitoring and evaluation of patient outcomes. Important research considerations include the following: selection of research sites and the particular NCDs targeted; research methodology; local research capacity; research collaborations; ethical issues; translating research findings into policy and practice and funding. Meeting the research needs for an improved health system response is crucial to deliver effective, affordable and equitable care for the millions of people with chronic NCDs in developing countries in Africa.
