Information Systems have been around for a long time, whereas, the term Information Technology is relatively new. The U.S. Postal Service could be considered an information system with sub-systems including logistics, and transportation. With a system of main post offices and community locations, the Postal Service is able to move letters and packages around the world in only a few days. Since the introduction of computers into the business industry, Information Systems focus on making use of technology to disseminate information. Information Technology could be considered a sub-system of Information Systems since the technology supports and enables the system through software and hardware development. The five main components of an information system are people, hardware resources, software resources, data resources, and network resources. (2010). People include the end-users and also the programmers, analysts, and other technical specialists that support the system. Hardware resources include the servers, client workstations, monitors, keyboards, and all other peripherals that interconnect them. Human interface devices allow users to input data to the system, which is translated into usable information. Software resources include the system operations programs, such as Windows, or Unix, and application software that are specific to a particular task, such as, word processing or finance. Included with software resources are the procedures for the use of the program. Data resources can include graphs, sounds, and any form of written communication. Data can be organized in a database to hold processed and organized information, or as a knowledge

Evolution of Health Care Information Systems

...Evolution of Health Care Information Systems Since the early 1980s, the U.S. health care system has experienced a rapid growth in the sector of health care information technology. This growth can be viewed as an attempt to standardize our fragmented health care system. The health care information technology is no longer an option but a necessity to be compliant with the mandated federal regulations. President George W. Bush in 2004 asked health care providers to implement Electronic Health Records (EHR) by 2014. The Joint Commission for the Accreditation of Health Care Organizations (JCAHO) and Health Insurance Portability and Accountability Act (HIPAA) also joined this initiative by asking health care providers to be compliant with the new legislation. Many community-based physician practices previously reluctant to embrace technology are realizing the benefits of the health care information systems, such as computerized physician order entry (CPOE), electronic medical records (EMR), tele-medicine, complex disease management, and automated billing systems. The purpose of this paper is to compare and contrast a contemporary health care facility with a health care facility of 20 years ago. Additionally, the paper will identify at least two major events and technological advantages that influenced the current health care information system (HCIS) practices. Definition of Health Care Information Systems Prior to discussing the evolution of HCIS in the last two decades, it would...

Mobile Technology in Monitoring Patient Vital Signs

...Oluwadamilola O. Adeyemi Dr. Msthali CIS 500 November 16, 2012 In comparing and contrasting using mobile technology to the ageless standard of in patient visits and all the procedures handled within the office or hospital setting, vital signs have been measured frequently to access the condition of a patient. Since the days of Florence Nightingale who is the mother of nursing, the standard in health care has been that taking the patients vital signs has always been a hands on in person experience. This at many times has caused days of agony and drudgery as you would deal with the discomfort of having to sit for hours upon hours in an office field with coughing, sneezing, hacking, wheezing and nauseous individuals. Each visit leaves you feeling that at any time, you may leave this office visit in a worst condition than when you came in. The assessment and monitoring of patient vital signs has typically been looked upon as one of the most routine aspects of nursing care. Monitoring patient vital signs became so mundane that usually the responsibility of taking the vital signs, even though ordered by a physician would end up being handled by a lowly Patient Care Technician. While in the hospital, vital signs are monitored on a scheduled basis. This is only interrupted if there is a change in the patient’s condition, the worse the change, the greater the increase in scheduled vital sign monitoring. However, this can also be affected by nursing judgments which...
