In medical field computer literacy is important to what extent, & where computers are used in field of medical. IMPORTANCE OF COMPUTER IN MEDICAL FIELD Computers are the excellent means for storage of patient related data. Big hospitals employ computer systems to maintain patient records. It is often necessary to maintain detailed records of the medical history of patients. Computers can keep track of prescriptions and billing information. Doctors often require the information about a patient’s family history physical ailments already diagnosed diseases prescribed medicines Computers enable an efficient storage of huge amounts of medical data. Computer storage can serve as the best means of housing medical information. Medical journals, research and diagnosis papers, important medical documents and reference books can best be stored in an electronic format. In the field of medicine, computers allow for faster communication between a patient and a doctor. The importance of computers cannot be stressed enough as computer technology has revolutionized the field of medicine. USES AND PURPOSE Diagnosis CT Scan X-Ray Generator Ultrasound Telemedicine Surgery Hospital Information System Data Analytics in medicine Computer Assisted Decision making (CMD) LIMITATIONS IN DEVELOPING COUNTRIES Limited access of technology in developing countries Lack of funding Lack of resources ADVANTAGES High tech surgery tools and instruments embedded with cameras are used in surgical process. The operations done by the medical experts are completely recorded by the computers for future references and to avoid complications. Computers make their role perfect in all types of clinical image processing like CT scan X-rays and more accurately. The Heart Rate, the Pulse Rate, Brain readings and others specifications are monitored and recorded continuously. DISADVANTAGES Cost One of the biggest drawbacks of adding computers to hospitals is the cost. Computers cost money, and a large hospital needs many computers to keep the system running smoothly. Security If doctor or hospital is switching to computers or electronic record keeping, it’s a dangerous thing i.e. security of medical records. Lack of Standardization From a hospital point of view, one of the biggest disadvantage of adding computers in medical field in lack of standardization through the medical field. FUTURE DEVELOPMENT AND USES Tele-surgery: Telesurgery is an emerging surgical system that utilizes wireless networking and robotic technology to connect surgeons and patients who are distantly located from one another. Full Robotics operation Silicon computer chips maybe used to repair nerve damage or muscle fiber. Feeling of pain can be reduced using virtual reality helmets.
