Question: Identify computer components and technologies used to support the development of healthcare and management of health data and information.? Describe emerging technologies that support the creation and maintenance of electronic health record (EHR) systems.? Describe the development life cycle of information systems.? Answer: 1. Identify computer components and technologies used to support the development of healthcare and management of health data and information. Components of healthcare information technology will include the following, Electronic Health Records or EHR, is a collection of systematically collection of electronic healthcare information about the patients and populations of a locality. Records are stored and processed in electronic format and are shared across other systems and networks of hospitals and healthcare centers. HER covers a wide range of data including medical history of patients, demographics, information about allergies and medication. Results of laboratory tests, radiology images, immunization status, weight, height and other health information of patients, billing information for medical services etc. (Gartee, 2011) Clinical point of technology for healthcare like CPOE or Computerized Physician Order Entry is useful for reducing errors in medications. Thus reduces life threats to a patient. It includes technologies and support for electronic prescribing, bar code based systems for drug dispersion etc. any technology of system that can help in reducing medical errors, prescribing errors, medication errors, can be considered as CPOE technology.(Ground, 2008) 2. Describe emerging technologies that support the creation and maintenance of electronic health record (EHR) systems. An emerging technology that can support creation and maintenance of HER systems, is mobile based EHR technologies. iPad and android apps can help to use handheld mobile devices to use for EHR systems. (Hu, 2013) 3. Describe the development life cycle of information systems. System Development Life Cycle or SDLC has several steps through which the process of system development goes through. The phases are described below, (Shelly Rosenblatt, 2011) Planning and feasibility study of information system. It will help to understand whether the goals of the system development are achievable or not within the constraints of the system development process. System analysis and requirement specification will help to understand the issues with the current system and the expected functionalities of the proposed system. In analyses the requirements of the stakeholders. System design is the process of understanding the functions and features of the system, plan for system development, describe the system through modeling techniques, diagrams, pseudo codes etc. System development is the process of developing the actual system modules and unit testing the modules. It will need coding. Testing is the process of integration and system testing. In integration testing, modules are integrated one by one and tested. In system testing, the whole integrated system of modules is tested. It helps in understanding the interoperability of modules, bugs in the system etc. System implementation is the process of actual deployment, installation and acceptance of the system in the intended environment. Then there will be system maintenance phase throughout the life of the system. References: Gartee, R. (2011). orElectronic Health Records. Prentice Hall. Ground, A. R. (2008).
