Usability issues of Health Informatics in developed countries’ eHealth systems: A Critical Review

Healthcare Information Technology system’s integration requires a combined information in order to provide efficient and best care service delivery. Developed countries in eHealth systems are experiencing challenges in reforming health sectors. The usability aspect of eHealth systems is one of the problematic areas in the deployment and adoption of eHealth services internationally. This reform involved using different tools and approaches of integrated systems design. There is no doubt the IT supports these changes. However, lack of usability tools and integrated system’s concept have reduced the capability and productivity of the health informatics. This critical review illustrates the users’ involvement as part of integrated systems engineering which is vital for the successful eHealth service. This review demonstrates challenges and discussion analysis the term of usability issues of eHealth in several developed countries that supports future features of design methodologies in health informatics.
