Developing integrated health information systems in low income countries: an enterprise architecture approach

Abstract

In the last half-century the world has witnessed dramatic gains in health status. These are occurring in developing countries now but started in Europe and other wealthier countries around the global in the late 19th century and early 20thcentury. These improvements were partly attributed to increasing in education and income of the population which resulted in more hygienic living conditions and nutrition later in the 20th, expansion of health and public health services by governments and biomedical innovations. Sub-Saharan Africa still carries most of the global burden of disease with low life expectancy at birth with majority of deaths occurring to children under the age of 5 years. Infectious diseases are the major contributors to the disease burden in sub-Saharan Africa that affect the poorest in addition to noncommunicable diseases. The health system is a major determinant in reversing this burden in sub-Saharan Africa. Health systems in sub-Saharan Africa are weak and need to cope with simultaneous communicable and noncommunicable epidemics. Health information systems play a significant role in steering health system strengthening and documenting progress as it provides reliable information on health determinants, health system performance and population health status. Despite its importance, health information systems in many developing countries are weak, fragmented and often focused exclusively on disease-specific programme areas. Integration of health information systems will provide the basis for public health professionals to look at the health system from different viewpoints. Enterprise architecture (EA) is a management tool that provides means for aligning information systems with organisation’s mission, goals and objectives. EA is used to develop a comprehensive description of all of the key elements and relationships of an organization and its alignment with an organization’s mission, goals, and strategic objectives with information systems. EA can be used as a method for designing health information systems in terms of a well defined set of building blocks, and showing how the building blocks fit together and how they communicate with each other. This research aims to study the potential of EA as a strategic methodology that can be used to systematically gather and document health information system requirements to design a unified comprehensive health information system that integrates data from diverse sources at all levels of the health system for localised evidence-based decision making and health systems strengthening. This research used qualitative method to collect primary and secondary data. Primary research data was collected through in-depth interviews with key stakeholders and observation and discussions in workshops and meetings. Secondary research include desk research by searching for published and unpublished research outputs, white papers, reports, user manuals and training materials. Gathering and documenting requirements and processes that facilitate systematic design and…
