At that time, the main purpose of computerization was labor-saving for the process of insurance claim and the scope was limited only within administrative section in medical institutions. The physician order entry system (POES) appeared in 80s by a centralized system of a host computer and based on the computerization of clinical laboratory and pharmacy. The POES contributed reducing patient's waiting time in clinical institutions and also making the process of Insurance claim efficient. The growth of networking, especially the Internet in 90s enhanced cooperation among clinical professionals or clinical institutions. Also, the electronic medical record (EMR) came into realistic and a hospital in the west of Japan implemented EMR and got rid of paper first in 1999. In 2001, Japanese government established e-Japan policy, and health care and social welfare is one of the main target fields. Then, the ministry of health labor and welfare (MHLW) published "IT ground design for healthcare system" in the end of 2001. It focused on EMR and the national standard software for electronic prcH2ess of insurance claim. It made target to implement by the end of 2006; over of institutions which has more than 400 beds should install EMR and over of institutions should install the national standard software for electronic process of insurance claim. According to the survey by the MHLW in 2002, only 1.3% out of total 8,023 hospitals have EMR and 15.3% have the POES. 3 It is also only 2.3% that the percentage of hospitals installed the national standard software for electronic process of insurance claim. However, such numbers are dramatically increasing recently. As overall, computers are very popular among Japanese people and international survey in 2003 showed that had laptop or desktop computers in 2002 and had a mobile phone in 2003 in Japan. The corresponding numbers for the US were 66% and 54%. The percentage of the Internet users were 45% for Japan and 55% for the US in 2002 (ITU Telecommunication Indicators). There has been a rapid expansion of computer use in medicine recently in the US for a number of uses including medical education at all levels, point of service medical information (especially diagnostic, treatment, and medications), medical research, EMRs, electronic billing, electronic prescribing, and the collection of data to determine quality of care and quality of medical education. Some possible reasons why computers are increasingly used in US medical care are availability of high speed connections, availability of personal digital assistants (PDAs), availability of wireless connections, decreasing cost of hardware and software, public and government demands for increased quality of care and documentation of that quality, too much information to process without electronic help. Wireless LANs are much more common today in hospitals than in doctors ' offices. Only about 8 percent of physician practices have gone wireless. By comparison, 61 percent of integrated delivery networks and 36 percent of stand-alone hospitals have some wireless capability in the US. In terms of security, wireless network should be protected, at least, by a combination of wireless-specific ways such as WPA/EAP according to IEEE802.1X with 4 IPSec/VPN technologies. In addition, a separation of traffic by creating VIANs, and installation of a firewall between wired and wireless networks tightened the security of the MIPA/EAP-equipped wireless networks. How can computers Improve quality of care and document that quality? They can avoid illegible hand- writing, can be programmed to find errors in dosage, medication name, medication interactions, and identifying allergic patients or the wrong patient, computerized records can be backed up and are less likely to be lost or unavailable, computerized records can more easily be transferred even over long distances, more easily collect data such as mortality or number of patients seen or types of diagnosis seen. How can computers improve medical education? They can decrease the amount of class time where there is information transfer without interaction, Increase the amount of class time available to answer questions and concentrate on confusing or difficult topics, teach medical students and residents how to efficiently get the most accurate, useful, and up to date information through computer programs. They can then use this technique for the rest of their career. Computers can decrease the amount of information needed to be memorized and reduce the chance of error due to faulty memory. Finally, they can decrease the amount of time needed to read journals and books while still maintain high quality knowledge. What are the disadvantages of computer use in medicine? They can be less useful for those physicians who cannot type quickly, take extra time and effort to get used to, create psychological discomfort with a new way of practicing medicine, be vulnerable to viruses and technical problems that risk loss of data unless backed up, be vulnerable to 5 breaches of patient confidentiality, sometimes increase the amount of time needed to get work done, create fear that computerized data can be used by the legal system against doctors and hospitals, create the fear of making the interaction between the patient and doctor seem less personal and have 6 CHAPTER TWO LITERATURE REVIEW The electronic devices supplied with processing units became an important component of our everyday life. Computers, smartphones and other apparatuses that give us mobile access to Internet are fundaments of modern business, education and sometimes even relationships. Health care as a vital part of contemporary society model is also affected by the same technical trends as the other branches of business. As personal healthcare is among most important aspects of everyone life many efforts are put into medical researches on new treatment techniques. Because of that, all computer methods that have proven to have technical and scientific potential are quickly developed and utilized in medicine. Now it is impossible to mention all possible applications of computers in contemporary medicine because nearly all aspects of applied informatics are used in practical medical solutions. The motivation of this article is presenting subjective list of up to date applications of computer methods in medicine that might be good introduction to this subject. In our opinion the role of computer methods in medicine is changing as quick as computer science itself and there is a need for this type of review. Moreover, we will describe our contribution to the state of the art methodology by introducing some of our projects and achievements in this subject. Our work is mainly concentrated on two- three- and four dimensional image data: image processing and recognition (classification tasks), semantic interpretation, as well as visualization and user interfaces. The data we are dealing with are mainly medical 7 images acquired from patients with suspicious of early stages of brain stroke. The proper diagnosis of medical data in first hours after appearing the stroke syndromes is crucial not only for patience live but also for further convalescence. Computer is playing very important role in medical fields. Nearly every area of the medical field uses computers. They are helping the doctors to diagnose diseases and for many other purposes. The four main/major uses of computer in medical field are described below: 1- Patient Monitoring Different electronic scanning devices (medical equipment) are used in hospitals. They are connected with computers. These devices are used to monitor the patient continuously. Thus computers are normally used in the following medical units of hospitals for monitoring patients. o ICU (Intensive Care Unit) o Operation Theater o Recovery Room o Medical Ward o ECG (Electrocardiograph) The medical equipment with sensors is attached to the patient. It detects changes in heart rate, pulse rate, blood pressure, breathing and brain activity. If any unbalancing situation occurs, computer activates the alarming device, which creates sound and alerts the medical staff. 8 2- Maintaining Patient History & Other Records The complete bio-data as well as medical history of a patient is recorded into the computer. The medical history is delivered to the related doctor for the checkup of the patient. In this way, much of the doctor's time is saved. In addition to patient history, other information about doctors, medicines, and medical equipment is also maintained through computers. This information can be retrieved very easily and quickly. 3- Diagnosis & Surgery Computer is also used in hospitals for diagnosing diseases. Different medical tests depend upon the computerized devices such as laboratory test of blood. One common use of computer in hospitals is to scan the body of patient. A special scanner is used for this purpose. For example, the CAT (Computerized Axial Tomography) scanner passes rays over the patient. It displays an image of bone and tissue structure of patient on a computer screen. This image is printed on the printer. It is also store in computer for later use. 4- Research. We would look at them one by one. 9 PATIENT MONITORING In medicine, monitoring is the observation of a disease, condition or one or several medical parameters over time. It can be performed by continuously measuring certain parameters by using a medical monitor (for example, by continuously measuring vital signs by a bedside monitor), and/or by repeatedly performing medical tests (such as blood glucose monitoring with a glucose meter in people with diabetes mellitus).
