Mapping the Metrics of Radiology Technology Diffusion: A Case for Swaziland

In recent years Swaziland's medical field has been graced by computerised data collecting systems and the installation of computer work stations in most health care facilities. This was in response to the invention of new and improved imaging technologies in high income countries. Establishing the impact of this development requires investigation of predictor variables such as perceived ease of use, perceived usefulness and the technology diffusion pattern as it varies from one country to another. In this complex landscape, the objective of this study was to establish how these predictor variables modelled technology diffusion in Swaziland. Data collection involved both passive and active data sources using questionnaires, interviews and observations in a complemental manner. An 83% response rate was obtained from the study. The results revealed that technology diffusion in Swaziland was currently at its peak modelled mainly by the perceived ease of use and the perceived usefulness of the new technologies. The peak of the diffusion of technology was in the second decade of the 21st century with the most advanced technologies being in the private sector. A more extensive study to cover imaging centres excluded from this study is recommended. An investigation into technology diffusion extending to interventional radiology practices, role extension for radiographers and funding models may support improved technology diffusion mechanisms.
