The Domain Of Service Oriented Architecture

There was no standard way of keeping patient data on healthcare applications. There was no communication between software companies on how interfaces in healthcare applications were to be built hence software applications were not compatible with each other. It is important that healthcare organizations follow the same standards when setting up their healthcare information system, thus creating interoperability so that the sharing and exchange of information within and across healthcare providers is facilitated. As a result, a volunteer group introduced the Health Level Seven Standard (HL7) for healthcare organizations to follow the same standards when developing their healthcare information system so that data can be shared seamlessly. In a nutshell, HL7 was introduced for the following

A legacy system is an important topic to address because of its magnitude within a health care organization. A legacy system can be a health care organization information system, nurse scheduling system, purchasing and inventory control system, admission-discharge-transfer systems, and facility planning system ( ). Any EHR system considered by a health care organization has to take into consideration the compatibility with the legacy systems already used within the facility. One of the most popular EHR platforms is the cloud-hosting services because installation is minimal and the cost is based on the number of embedded applications needed. In the article, " " by talks about how middleware has the opportunity to connect and gather data from different EHR systems once

purposes of this paper, only PaaS and SaaS will be discussed. According to the Chief

Writer received a call from Marvin concerning her SPOA application. Care manager used that opportunity to formally introduce myself, and also asked when he applied. Marvin had no knowledge of it but he shared his counselor's number with me to call her for details about the application.

The Web architecture should describe and justify operating system choices (i.e., Linux, Apache, MYSQL, PHP, Windows, IIS, SQL, etc.).

In today’s modernized society, health care organizations rely heavily on information systems. Information technology has improved tremendously over the years, becoming a major advantage to the health care industry. With proper planning, development, and management, information technology can bring about countless efficiency in structural maneuvers. With the constant changes in technology, a health care organization must stay up-to-date on technology and the lasted trends that offer the best patient care possible. Information systems designed for health care industries must help the organization meet the

The American Medical Informatics Association (AMIA) (2017) defines informatics as a futuristic method and driving force in innovation concerning the science, study, and practice of generating, storing, discovering, manipulating and distributing data. Interoperability is the capability of multiple systems or components to exchange and utilize data (Nelson, 2016). Furthermore, the two concepts of informatics and interoperability lies at the foundation of the maintenance, expansion, and success of the current health care system. At present the single facility hospital no longer exist. Now, the main hospital is the trunk of a tree that have multiple branches and roots consisting of administration, vendors, special

However, with every decision there is some bad news, for instance “the time it takes... how hard it is to change the processes, get buy-in, roll out the system without too much scope creep, train the people, make customizations, fix problems that crop up after implementation. (Glasner, 2007)” The negative news is a big challenge since there is no real establish market for SOA, the costs and time to get trained will be very stressful because not all persons will understand the process very fast. More nurses and doctors will need to take time to understand the new IT system and figure out the method that will be agile for physicians and privacy of patient

First, any system must take into account the cultural and organizational characteristics of the institution at hand. One size does not fit all in the case of most healthcare applications. The ability to modify the application based on the sociotechnical abilities, and to mold it with based on the organizational, human, and social aspects (clinical workflow) can better assure acceptance and adoption of the system. Ideally, with each iteration the software specialists interact with the users to improve the application in each specific

Healthcare organizations are struggling to keep up with the interface development demand, and the problem is growing. The medical web experts offer custom health interface development services for connecting with EHR/EMR, as well patient portals and HIE systems. Over the years, many interfaces use variety of technologies and standards, as an example; HL7, CCDA and API technologies that do not meet standard.

One of the largest U.S. hospital management companies is Hospital Corporation of America (HCA). The Hospital Corporation of America was founded in 1968. It’s the nation’s first hospital companies and now the nation 's leading provider of healthcare services with about 165 hospitals, 115 freestanding surgery centers, and employs around 204,000 people (“Hospital”, n.d). Besides offering traditional services, HCA has been a leader in the ever growing for-profit medical-services and hospital-management industry which cause them to achieve a strong international presence. HCA is ahead on its considerable debt payments, incurred when the company went private, but still faces challenges. It is difficult for non-HCA physicians and physician office staff using non-HCA devices (e.g. personal computers, etc.) to remotely access their patients’ data on the existing HCA clinical applications. Because of this difficulty users (non-HCA physicians) are likely to send their business to an HCA competitor if that competitor provides easier access to patient information than HCA (Encyclopedia, 1982). HCA mission is to puts patients first and find ways to constantly improve the care we provide. By introducing a virtual desktop infrastructure (VDI), HCA will be able to meet their mission of constantly improving care we give to our patients and empower our employees (by centralizing user access) (“Hospital”, n.d). Most importantly HCA will be able to stand above our competitors

Health information systems (HIS) are complex and it is helpful to understand advantages and disadvantages to some key components of a HIS. This section will describe the advantages and disadvantages of usability, interoperability, scalability and compatibility.

PH’s patchwork IT infrastructure is in critical condition, so it has major IT infrastructure problems. CEO of PH Max Berndt is trying to find the right solution. He has an option to go with a single set of systems and applications (Monolithic System) that will provide consistency across PH’s facilities but may not give doctors enough flexibility or he can choose service-oriented architecture (SOA), a modular design that will allow PH to standardize incrementally and selectively but poses certain risks as a newer technology.
