The availability of health information in South Africa.

The South African Medical Research Council (MRC) has provided access to on-line health and biomedical information since 1976, when the MRC became an international partner of NLM. This was done to support research and health care when the Institute of Biomedical Communication was established. The institute has since reorganized and is now the Information Systems Division in the Research Systems Support Group MRC. he MRC and medical libraries in South Africa are able to access various automated services via telecommunication. The major systems available are MEDLARS, DIALOG, DATASTAR and BRS, with ECRI being the latest addition; most used are MEDLARS and DIALOG. New technologies (e.g., CD-ROM) have given more people access. This technology is not available to many people working in Primary Health Care (PHC), as they do not have access to computer networks. Beyond on-line is statistical and printed information, called "Gray Literature," not accessible through on-line systems as it is not published in conventional sources used to build databases. With a shift to Essential National Health Research and the focus on PHC and preventative medicine, demand for health information and "gray literature" is growing. The MRC collects and produces this material and has its own database called SAMED, which is to be made available to others as our contribution to health. It is hoped to make this available for inclusion in the proposed African Index Medicus presently investigated by the World Health Organization. Africa as a continent, and South Africa as a country, are experiencing major changes in health care and medical practice, and inevitably, provision of health information services. With South Africa's re-entry into the global village and its acceptance by the rest of Africa, it can be a key player in information provision to the rest of the continent. The MRC, as a major provider of Health information, can play a vital role in the information flow throughout Africa by continuously improving and expanding its services. A large proportion of South Africans live in rural areas where health care is provided by clinics not linked to information networks. This does not mean these clinics are excluded from the use of information. The major challenge is to find the ways and means of getting the relevant information to these clinics. Information is needed to help with patient care and continuing education. With this in mind, the MRC is evaluating different formats in which information can be supplied. Due to the lack of computer literacy, facilities, and financial constraints, it is better to supply printed information. With the spread of technology through the country and continent, it can be assumed that information flow and transfer will be more rapid. Repackaging of information means that it is possible to get the relevant information to the right people at the right time. The first such package developed is for hospital managers. With the help from experts in the field of PHC, it is hoped to develop packages aimed specifically at the CHWs and other workers in the field. All packages developed by the MRC are backed by a document provision service, using the most cost-effective route to obtain documents. A printed product must comply with certain criteria; these are: 1) purpose for which the information is needed; 2) kind of information needed and the format in which it is needed; 3) when the information is needed; 4) is the information to be supplied on an ongoing basis i.e., updated with latest information; 5) cost involved; and 6) how to get the information to the relevant user.
