It fosters advancement of health discovery and knowledge this includes the development of how strategies to cater for diseases; identifying new means for delivery of services methods, decisions models and practices; promoting health knowledge advancement: making strides in quality improvement; managing trials in clinical and research quality; and provision of practitioner education. The ARIS System The major effort in most of the health organization has been the creation of Enterprise Architecture for all medical systems.
The army, Air force, navy, Marine Corps and other defense Departments will maneuver under the new system (EA) which should let their systems interoperate seamlessly. One little-known controversial process is an effort to revamp the way the military community is structured. The only goal is to integrate their medical services and facilities to reduce redundancy and serve the patients better. The use of Enterprise Architecture should always increase the efficiency and effectiveness of the medical logistics supply chains that will provide goods and services to that will support the troops.
Defense Medical logistics brought in the IDS sheer Inc, of Berwyn, pa. , to develop their new Enterprise Architecture using the company’s platform called ARIS which is a business process management tool. ARIS is supported by an integrated repository, so the data can be exchanged and processed access many solutions. All user groups like Information Technology and management departments work in an integrated environment using the ARIS. According to Ed Tom, IDS sheer’s consulting services Manager, before they had implemented the ARIS system, there were a whole slew of applications and systems were not really integrated together.
The systems were separated into many smaller modules. Field hospitals in theatre were one of the modules while medical treatment facilities in the United States and abroad were another module. There was no single collection available that showed Defense Medial Logistics leaders that the applications and systems existed. The visibility problem was totally removed by the new enterprise architecture (Mukherji, 2002). The new enterprise architecture is designed and intended to continue the interoperability effort which is called the Defense Medical Logistics Standard Support Program.
According to William Warden of Defense Medical Logistics Directorate of Medical Materiel, despite the success of the support program in developing integrated applications each organization in the defense medical logistics enterprise retained considerable latitude to deploy IT solutions. The approach formed replication and ineffective end to end process management but with the new Enterprise architecture the problem started diminishing. Before creating the new enterprise Architecture little operational process modeling was used to manage the logistics community business process.
One of the important features of the new enterprise architecture was to establish service oriented design requirements. This was confirmed by Greg Deller, the principal consultant at Enterprise Integration Inc. According to Deller service oriented architecture allows the integration of many different systems instead of forcing them all to be one system. Many systems in medical logistics perform many different functions. For example, on board a ship a single system might be able to mange food supply, medical and repair part logistics.
This kind of combination makes it impossible to stop using the old systems in favor of the new ones (Spewak, 1992). SOA System Improving Performance of E. A. health care systems using service oriented Architecture (SOA) Advancement in technology and its adoption into the health care systems had made most of the health care organizations to collect an accumulation of systems that are not interoperable and that not only need to work together within the institution but also are accessible from outside. Users have the burden to integration because they are forced to access many different systems to complete a single task.
The use of service oriented Architecture (SOA) can however improve the delivery of crucial information and make data sharing across a community of care practical in cost risk of implementation of security (Mukherji, 2002). Use of SOA in Health Information Technology A single system in a health care organization can support various departmental and care delivery needs through sharing and re-using system resources. An organization that depends upon more enterprise systems is more typical and supports departmental needs with additional systems.
It has facilities that utilize their own instances of systems and interoperates using a very complex network of data interfaces. An organization with large system portfolio will more readily perceive the benefits of SOA. A SOA environment therefore enables systems assets to be accessed across the network of an organization, providing more opportunities for system sharing capabilities that are presently inaccessible. A good example is that SOA can help to meet and fulfill the requirements without the need of purchasing more systems and it can also provide opportunities to standardize processing and data management.
This means the existing system capabilities will increase in value as they are shared and packaged as services (Nas, 1996). SOA defines a service as an independent module that is self controlled and has well defined and well understood capabilities. The module or unit of work may be process, a function that supports a process, of a step in any business process. SOA services support business processes directly as they are exposed and coordinated as a system solution.
The best opportunities for using SOA to increase re-use and standardization are provided by those roles that are applied across systems, departments and the overall organization structure. If system function becomes unnecessary and redundant across systems then the corresponding business processes and procedures are likely to be related and may indicate the need for process sharing as services. In the health care systems, the functions with substantial redundancy are. Patient Register Admit discharge and transfer patient Capture and document charges Document problem and diagnosis Create clinical
