The expansion of ICT across Africa is influenced by many factors including political imperatives, donor priorities, private sector and NGO needs, and economic interests and as a result takes place in a haphazard and largely uncontrolled fashion. The health sector is no exception. The challenge, as in many developing countries, is to provide a robust and reliable health information system while effecting a transition between paper-based systems and computerized systems. The transition involves not only the introduction of new ICT, and the accompanying social and educational transformations of people and processes that accompany the introduction of ICT, but also the development of scalable health information systems that can facilitate a smooth transition as ICT expansion and development takes place. This chapter draws on 10 years of experience of the Health Information Systems Programme (HISP), an action research orientated network of public health practitioners and academics who initiated a pilot project in health information systems development in the post-apartheid transformation of South Africa, and which has subsequently had a profound effect on the development of health information systems in Africa and Asia. Through an exploration of health information systems development in numerous countries in Africa, we highlight insights into approaches and methodologies that contribute to successful and sustainable health information systems in resource constrained settings.

AbstractRapid development of community health information networks raises the issue of semantic interoperability between distributed and heterogeneous systems. Indeed, operational health information systems originate from heterogeneous teams of independent developers and have to cooperate in order to exchange data and services. A good cooperation is based on a good understanding of the messages exchanged between the systems. The main issue of semantic interoperability is to ensure that the exchange is not only possible but also meaningful. The main objective of this paper is to analyze semantic interoperability from a software engineering point of view. It describes the principles for the design of a semantic mediator (SM) in the framework of a distributed object manager (DOM). The mediator is itself a component that should allow the exchange of messages independently of languages and platforms. The functional architecture of such a SM is detailed. These principles have been partly applied in the context of the HEllOS object-oriented software engineering environment. The resulting service components are presented with their current state of achievement.

The problems encountered in achieving data security within computer-supported information systems increased with the development of modern computer systems. The threats are manifold and have to be met by an appropriate set of hardware precautions, organizational procedures and software measures which are the topic of this paper. Design principles and software construction rules are treated first, since the security power of a system is considerably determined by its proper design. A number of software techniques presented may support security mechanisms ranging from user identification and authentication to access control, auditing and threat monitoring. Encryption is a powerful tool for protecting data during physical storage and transmission as well.Since an increasing number of health information systems with information-integrating functions are database-supported, the main issues and terms of database systems and their specific security aspects are summarized in the appendix.
