Health information systems are systems that enable healthcare workers to store, organize, and retrieve data as it relates to a specific patient. Advantages of a HIS would be increased efficiency and accuracy, ability to access and store data, and increased security of patient information. The main deterrent of a HIS is the initial cost of implementing it and the cost of upkeep and updates to maintain its usability, interoperability, scalability, and compatibility. Usability can be defined as how easy a program is to navigate, and how efficiently it completes a task. Advantages of usability are: higher customer satisfaction rates, increased productivity, and decreased medical record errors. If a system has poor usability an increase in medical record errors can occur, as well as, decreased productivity and customer satisfaction rates. Customer satisfaction includes staff and patients. Patients accessing their records from home, need an easy to use system. Usability depends on a number of variables, including but not limited to: appropriate font color and sizes, functions groupings, workflow, and tools that do not function correctly. Any of these could create issues that hinder productivity and accurate documentation. Interoperability is the ability of various systems and organizations to work together to exchange information (Mastrian & McGonigle, 2016). For example, being able to have different departments using the same application in different ways, but being able to
