IT in Health Care
A good healthcare system is a backbone of a developing country. Information Technology plays a very important role in
building a strong health care system. Let us study now the important applications of IT in health care system:
• Electronic Medical Records (EMR) system is used to convert medical information of patients such as medical history,
medications, insurance information, etc. into a single database that can be easily accessed by hospital staff and doctors.
• Computerised appointments with the doctors can be easily
done.
• Medical devices with the latest technology are used in
diagnosis of diseases and in the operation theatre during
surgery. Some of the commonly used devices are ECG, MRI,
CAT, Cardiac Echo, X-Ray machine, ultrasound etc.
• Capturing the diagnostic information of a patient and
generating the reports.
• Computer-Assisted Decision Making (CADM) system helps the doctors to design the treatment patterns for the patients.
• Health care manufacturing companies use computers to aid the production of diagnostic tools and medical
instruments.
Use of ICT in Diagnosis
With the advancements in computer hardware and software technology, various high-tech machines are used in the
diagnosis and treatment of critical diseases. Using an expert system, diseases can be diagnosed at the early stages and
the patients can be given treatment accordingly. Some of these machines are:
• Computerised Axial Tomography Machine (CAT): Using this machine three-dimensional (3D) images of different
parts of the body can be made. These images are helpful in the diagnosis of diseases.
• Magnetic Resonance Imaging Machine (MRI): MRI machines are used to give the digital impression of internal
organs of the body by using strong magnetic fields and radio waves. The digital images are very helpful in the
detection and in deciding the treatment of diseases.
• Electrocardiogram Machine (ECG): The ECG machine is used to monitor the heartbeat. When the heart pumps
blood to different parts of the body some electrical impulses are produced. This machine records the electrical
impulses and shows it in the form of a graph.
