Overview of the Most Important Open Source Software: Analysis of the Benefits of OpenMRS, OpenEMR, and VistA

In this chapter, the authors review software that enables the proper management of EHR. The different types of software share the feature of being open source and offer the best opportunity in health care to developing countries—an overall integrated approach. The authors analyze the main free software programs (technical features, programming languages, places for introduction, etc.). Then they focus on the description and the comparison of the three most important open source software programs EHR (OpenMRS, OpenVistA, and OpenEMR) that are installed on two operating systems (Linux Ubuntu and Windows). Finally, the authors show the results of the various parameters measured in these systems after using different Web browsers. The results show us how the three main EHR applications work depending on which operating system is installed and which web browser is used.
