Health informatics is a discipline at the intersection of information science, computer science, and health care. It deals with the resources, devices, and methods required to optimize the acquisition, storage, retrieval, and use of information in health and biomedicine. It include computers,clinical guidelines, formal medical terminologies, and information and communication systems. It is applied to the areas of nursing, clinical care, dentistry, pharmacy, public health, occupational therapy, and (bio)medical research. Computers play major role in this.
ROLE OF COMPUTERS IN MEDICAL FIELD Maintaining Record System Billing and Financial System Analysis Material Management Radiology Clinical Management Tracking Patients
ADVANTAGES Computers are mostly used in every organization. Computer plays different roles in different fields now a day’s no field is evolving without the role of computers. Computers become a reliable product in every hospital due to its effective and efficient performance. From open heart surgery to X-Ray’s everything is made possible so easily only through computers. Apart from administration purposes computers are used in performing surgeries. Laparascopic surgeries is said to be the most common surgery which can be done only through the help of computers. The medical experts insert the medical tools and other small equipments attached with cameras into the patient’s body.
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 also 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, pulse rate, brain readings and other specifications are monitored and recorded continuously through computers and finally the medical expert analyze the computer record and provide treatment for the affected person. Always up to date
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. Creating a network to transfer medical records or keep track of billing is an additional initial cost. Unlike paper records, which simply require a few more copies, electronic record keeping requires constant upkeep of computers, computer software and other electronic elements, which can cost even more.
DISADVANTAGES Security If your doctor or hospital is switching to computers or electronic record keeping, youre probably worried about the security of your medical records. Paper records are kept in a doctors office or a warehouse, but once computers are added to a hospital, electronic record keeping typically follows. Once electronic record keeping is begun, medical information is usually added to a closed computer network, but as long as an Internet connection comes into the network, the system is vulnerable to outside sources, opening the debate to questions about patient privacy and medical record security.
DISADVANTAGES Lack of Standardization From a hospital point of view, one of the biggest disadvantages of adding computers and electronic records to a hospital is the lack of standardization through the medical field. Different hospitals use different shorthand abbreviations or symbols on medical records than others. Even the codes called out during emergencies dont always mean the same thing in every hospital. If a medical record is transferred from another hospital or the system becomes open so hospitals can share information, the lack of standardization in hospital notes and records could cause problems when it comes to a medical professionals understanding of the medical record.
Creating discipline at the intersection of information science, computer science, and health care. It deals with the resources, devices, and methods required to optimize the acquisition, storage, retrieval, and use of information in health and biomedicine. Helpful and Precise working system. Due to rapid expansion of medicine a number of uses including medical educations at all levels , point of service medical inf.(especially diagnostic, treatment and medications) and nowadays robotic surgery. The main object of such smart instruments is to reduce or eliminate the tissue trauma traditionally associated with open surgery without requiring more than a few minutes training on the part of surgeons. This approach seeks to improve that lions share of surgeries, particularly cardio-thoracic, that minimally invasive techniques have so failed to supplant.
