Infromation Systems for Healthcare Management - Technology Role in Essay

Infromation Systems for Healthcare Management - Technology Role in Healthcare - Essay Example Technological advancements continue to climb, as the new generation i.e. youth shows curiosity in grabbing and exploring these new technologies for a new and bright future prospect. The current trend is leading information technology towards an essential skill that will make itself similar to writing, reading and the new skill called as ‘computing’ (CEO's guide to health care information systems.1997). The trend is affecting all sectors including the health care. As healthcare facilities are now equipped with integrated health care information systems including application software, network and data communications, access and data management, information processing, Wide Area Network, Local Area Network and Clinical decision support systems. Moreover, there are other network components including switches, bridges, hubs and routers. Before incorporating a network, system architecture is essential, as it will define the nature of data communication i.e. client / server arc hitecture or mainframe architecture. The second key consideration is the legacy system sustainability and integration. For instance, there are old systems that that cannot be removed instantly instead; data can be migrated gradually to the new systems, while the old system must also be operational. The third key consideration is the central data repository (CDR), as healthcare information systems interact with CDR to extract patient records, it will not be possible to replace the CDR completely (Clinical information systems for integrated healthcare networks). In order to integrate all the remote medical facilities, client/server architecture is the best option. The client/server architecture will incorporate a centralized interface engine connected to a central data repository. The implementation will be conducted on the nearest centralized medical facility. The computer network installation of client/server architecture will incorporate switches, bridges, hubs and routers. However , in order to make a centralized network operational, LAN architecture installation is required for each location. The installation includes CAT 5 cables, the quantity of a network switch depends on how many users needs access to the system. Moreover, Wide Area Network (WAN) device, which will connect each location. WAN is defined by network dictionary as â€Å"A Wide Area Network (WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect multiple smaller networks, such as local area networks (LANs) or metro area networks (MANs).† However, bandwidth requirements vary and depend on the core healthcare application. The legacy system integration in terms of organizing data is essential, as these systems do not share data with other sites. The solution for this issue is to collect the data in a portable device and store it in a central data repository (Clinical information systems for integrated healthcare networks). In order to integrate legacy systems on the new LAN architecture, an Ethernet card and system software installation is required. However, the installation process is not time consuming. The central data repository is a centralized location on the network. In order to connect each medical facility with the CDR, network connectivity is vital. If any of the workstation disconnect, the required data cannot be achieved. As previously, employees do not face such issues due to data availability on

If the expectations hypothesis of the yield curve holds, then the Essay

If the expectations hypothesis of the yield curve holds, then the government cannot - Essay Example In December, 2001 the yield on the Treasury notes which were issued for the period of ten years stood at 5.15 percent. The percentile was responsible for the negative change in the long term interest rates during certain periods, however the terrorist attacks conducted on 11th Sept, 2001 created a major impact on the interest rates, and reported a massive downfall in the long term interest rates, which had almost dissipated by the end of the year. The analysts have linked the fluctuating short term and long term interest rates with the reduction in the fund rate, 'by conventional wisdom, reducing the funds rate by the magnitude experienced last year should have had some impact on long term interest rates' (David, 2002). It is incorrect to associate such a pattern with the ineffectiveness of the monetary policies; rather it is the influence and effectiveness of the monetary policies because of which 'the long rates have failed to budge as short rates have plunged' (David, 2002). The ability and authority of the Central Bank towards providing liquidity, without creating any major impact on the inflation in terms of rise, is the parameter for evaluating the effectiveness of the monetary policy. ... In some of the related cases, the coincident features of the economy, which are based on 'the reversals in the stock market, poor corporate earnings, rising unemployment, elevated perceptions of risk' (David, 2002), such situations and conditions are expected to encourage the savers and lenders to move towards such assets which have greater concentration of liquidity, and are based on shorter duration for maturity. Such situations are expected to 'inevitably drove down short term security yields relative to those on longer term assets' (David, 2002), due to the reason that expectations with reference to the stability of the inflation figures are prominent. These forces are responsible for the generation of an environment in which short rates, including the federal funds rate, decline at massive scale, and have 'relatively little effect on rates at the longer end of the maturity spectrum' (David, 2002). It has been argued that the stability of the inflation figures was based on the lo wer funds rate. It is therefore commonly believed that, 'if recession and wobbly confidence have driven interest rates down especially short term rates, recovery and restored confidence will, sooner or later, drive them up' (David, 2002). Yield curve is a basic theory which correlates and interprets the interest rate developments over the past year and what it might offer in the future. The yield curve explains the relation and behavior of the 'returns to securities that differ in terms of the number of months or years in the future that the assets mature, or pay off' (David, 2002). The curve explains the relation between effects of maturity on interest rates. The Treasury securities operate at default risk, and are
