Medical informatics: developments in West Germany and South Africa.

Comparisons are made between medical information systems in West Germany and South Africa. In both countries the costs and importance of medical information systems dictate that a methodological approach is essential in order to obtain a solution for a particular environment. The special implications for South Africa are (i) to work from user requirements to computer system, rather than the reverse; (ii) to institute training programmes for the professionals required to organize and staff such systems; and (iii) to prepare the groundwork for medical information systems by scrutinizing the existing types, amounts, flows and uses of medical information.
