3. 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.
4. ROLE OF COMPUTERS IN MEDICAL FIELD
Maintaining Record System
Billing and Financial System
Analysis
Material Management
Radiology
Clinical Management
Tracking Patients
8. 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.
9. 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
10. 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.
11. DISADVANTAGES
Security
If your doctor or hospital is switching to computers or electronic
record keeping, you're probably worried about the security of your
medical records. Paper records are kept in a doctor's 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.
12. 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 don't 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 professional's understanding of the medical record.

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 lion's share of
surgeries, particularly cardio-thoracic, that minimally invasive
techniques have so failed to supplant.
