ABSTRACT: Systems’ usability is one of the critical
attribute of any system’s quality. Medical prac-titioners usually encounter
usability difficulties while using a health information system like other
systems. There are different usability factors, which are expected to influence
systems’ usability. Errors preventions, patient safety and privacy are vital
usability factors and should not be ignored while developing a health
information system. This study is based on a comprehensive analysis of
published academic and industrial literature to provide the current status of
health information systems’ usability. It also identifies different usability
factors such as privacy, errors, design and efficiency. Usability factors are then
assessed. Those factors are further examined through a questionnaire to study
the priorities of them from medical practitioners’ point of view in Saudi
Arabia. The statistical analysis shows that the privacy and errors are very
critical than the other usability factors. The study results further revealed
that availability and response time are the main challenges faced by the
medical practitioners when using the HIS. However, flexibility and
customizability were claimed to ease the use of the HIS. In addition, a number
of statistical correlations were established. Overall, the study findings
seemed helpful to designers and implementers to consider these factors for
successful implementation of HIS.
