Brazil built its public health education system through the work of the renowned Oswaldo Cruz Foundation, which established courses across the whole country. The courses eventually became the core curriculum for small schools and now Brazil boasts 40 schools of public health. Foundation President Paulo Buss argues that there are ways that resource-poor countries can improve their public health education.
Q. Do public health schools currently address public health needs worldwide?
A. Not really. There does not seem to be a sufficient number of public health schools and many of the less-developed countries do not even have one. In addition, countries do not have a uniform approach to public health education in terms of general orientation, content, standards and length of course. These range from short six-month courses in public health to specialized post-graduate programmes and a Master's of Public Health (MPH), Master's of Science (MSc) and Doctor of philosophy (PhD) degrees. Sometimes course content reflects the requirements of developed countries and not the local reality.
Q. How can resource-poor countries increase public health education to address their needs?
A. Public health workers are an elite representing less than 1% of the health labour force. Resource-poor countries can provide specialized training through distance education or in-service training, which can be accessible to a larger number of health workers.
Q. Are there specific areas in the curricula that need improvement?
A. In general terms, I believe that both epidemiology and management must be improved, emphasizing methodological, strategic and intersectoral approaches. In addition, special attention should be given to social determinants of health, health promotion and health economics.
Q. Are there any public health education success stories that spring to mind?
A. In referring to success stories, I would prefer to concentrate on the development of public health education in my own country, Brazil. The Sergio Arouca National School of Public Health (Escola Nacional de Saude Publica Sergio Arouca; ENSP) of the Oswaldo Cruz Foundation (FIOCRUZ), set up a short six-month public health course in each of Brazil's 27 states and employed teachers from the local university, professionals from the local health services and specialists from ENSP-FIOCRUZ. After five years or so, most of these courses were developed into small schools of public health. Later, the schools were expanded and upgraded to offer Master's and even PhD degrees. As a result the country now has a ratio of 0.97 public health officers per 1000 inhabitants. With more than 40 schools of public health, Brazil probably now has one of the greatest concentrations of training programmes in the world - one course for each 5 million inhabitants. Recently a Network of Schools of Health Governance was created with the objective of teaching governance to managers in health services and systems, and to assist them with the required technological tools.
Q. How can e-learning be successfully incorporated into public health education?
A. Increasingly, health services can count on a good computer network that permits long-distance education through e-learning, which can take place at the workplace. Ongoing education and refresher courses for trained public health professionals can also be implemented through e-learning.
Q. How can research in public health education be increased?
A. It is necessary to promote teacher training and research into instructional methodology and evaluation. It is also important to engage students to research different aspects of public health. A special effort must also be made to promote evidence-based public health research. I can especially recommend that an evaluation should be undertaken to ascertain whether current training is adequate to cope with the demands of public health practice.
Q. What is your vision for the future of public health education?
A. It must evolve to cover all levels of health workers, with an emphasis on the improvement of managerial skills. It must also include in-service training at undergraduate level and specialist post-graduate graduate programmes, Master's and PhD degrees. Brazil is examining the possibility of setting up an undergraduate public health course. This kind of training can lead to a wider distribution of public health skills to other professions. Much of what is taught in other health-based courses (medicine, for instance, is a pre-requisite to study public health in several countries) is not necessarily of great use for someone intending to pursue a career in this field. In low-income countries, one can argue there is no point of investing in training doctors when they do not need such advanced medical skills to be public health practitioners. It certainly would make more sense to prepare public health workers at technical or professional level in undergraduate courses.
