Definition Of Information System
Information is an organized set of seemingly related data. A system is a method, or process, of grouping things together. You may or may not have wondered how these two terms have combined and what helps them work in near harmony. This video grouping will help you discover the components and processes that make up the early 21st century's information system. Our formal definition of information systemsis the combining of users, technology and processes to complete a given goal. Users

Think about your daily routine. It doesn't matter if you are a student, working adult, someone's parent, retired or some combination of all of these, systems of technology impact you. For example, these videos are made with a broad variety of technological and human resources. You might access your school or employment record system or take a trip to the gas station to fill up or buy a gallon of milk. We all use these systems day in and day out, making us users of information systems. AKA Stakeholders

Another term for people who have an interest in information systems is a stakeholder. These can include anyone who makes use of the system - who's also known as an end-user - and the creative team, customers and anyone else who may be affected by the system. Let's take a moment to break down a very complex system into a really simple visual to show how an information system affects a hospital and its stakeholders. Let's say you're shooting hoops with your buds. You go up to jam, and you come down on the opponent's foot. Your ankle rolls and gives a great 'pop' you really didn't want to hear. Your friends load you up and take you to the emergency room. You go through the process of registration and triage. Your personal information is sent to a system that holds data and your basic medical information, such as vital signs, height, weight and the symptoms you're presenting. These may be entered into the computer system and held or documented on paper, passed along with your billing information and entered into the system later. You are then assigned to a bed and a nurse and ER doctor. Both of these individuals would have clocked in to a system that held payroll information. Their login and logout times are maintained until the pay period ends, at which time the payroll department combines their data with their personal information and processes the paycheck. Your nurse may take your vital signs and discuss the symptoms with you, marking them down in an electronic chart. She'll report the information to a doctor, who will then come to complete the interview and make an early diagnosis. The doctor might order lab work, X-rays, MRIs or CT scans. Again, these orders would be entered into the hospital's information system. Once the ordered tests are completed, the results of the lab tests and digital copies of X-rays, MRIs and CTs are tied to your record held in the computer system. Your doctor will then make his final diagnosis and either admit or discharge you. If you are admitted, your status would change from emergency room to admit and the bed assignment would be changed. Your on-call doctor would start a treatment plan, and once you're healed, you would then be discharged. When you're discharged, instructions are created, the visit is communicated to your personal physician, all services and materials used for the visit are transmitted to patient billing who will then create an invoice to send to your insurance company using electronic data interchange. The hospital then waits for the insurance company to return payment via direct pay. This combination of users, technologies and processes to complete a given goal is the information system, and it is vitally important to all the different stakeholders that will be a part of that system.
