Components of An information system

Components of An information system
HIM professionals are conventionally the business managers and custodians of data and information in healthcare.
An information system consists of four interrelated components—data, information technology, process, and users.
HIM professionals' traditional job roles make them the experts in managing data and processes in an information system. With the digitizing of information systems in healthcare organizations, the roles of HIM professionals have expanded into information technology (IT) and user support, which usually are the functions of IT supporting services. HIM professionals' training and experience in the intersection of clinical and management sciences as well as their knowledge about data quality equip them with the capability to maintain the integrity and accessibility of health information, although they may not necessarily have the particular skills to support technical operations of a health information system. For example, HIM educational programs usually do not provide courses in computer science theories such as algorithms or formal methods.
The delineating line between traditional HIM and HIT professionals has been blurred by the convergence of their functions and reporting structures in the electronic healthcare environment. Three areas of expertise have become the point of the convergence: 1) maintaining confidentiality and security of patient information, 2) using and maintaining data and information, and 3) terminology asset management.
Due to the convergence of the functions between HIM and HIT, professionals from both groups can work together to take a wide range of roles in the electronic healthcare environment.  These roles include joint educator or trainer, project manager, work flow analyst for clinical systems, privacy and security officer, EHR program manager, and data management and analytics professional. The authors claim that HIM professionals are no longer found exclusively in the record room as more HIM professionals step up to take information resource management roles in an electronic healthcare environment.
