            It is an application of computers, communications and information technology and systems to all fields of medicine; medical care, medical education & medical research. In fact, it is a combination of medical sciences with several technologies and disciplines in the information and computer sciences and provides methodologies by which these can contribute to better use of medical knowledge and ultimately to better medical care. It is the national study of the way we think about patients, and the study of how medical knowledge is created, shaped, shared and applied. It needs understanding skills and tools that enable the sharing and use of information to deliver health care and its promotion. Although, the name ‘medical informatics only came into use around 1973, it is a study that is as old as medicine itself. It was born the day that a doctor first wrote down some impressions about a patients illness, and used these to learn how to treat their next patient. By the advances in computer technology, information has grown considerably as a medical discipline in recent years fuelled. Clinical Informatics tends to replace the previously commoner term ‘Medical Informatics’ reflecting a widespread concern to define an information agenda for health services which recognizes the role of citizens as agents in their own case as well as the major ‑ information ‑ handling roles of the non – medical health care professions. Health information and computer sciences, psychology, epidemiology and engineering intersect at one place for advancing and teaching knowledge about the better health care to the community.

                 Clinical Informatics helps deliver the patient care, nursing and dentistry, electronic medical records and improves the quality of health care at reduced cost. We can create, give shape, show, promote and apply the health knowledge through clinical informatics. The scope of clinical informatics it thus enormous. It finds application in the design decision support systems for clinical practitioners, in the development of computer tools for research, and in the study of the very essence of medicine ‑ its corpus of knowledge. Yet the modem discipline of Clinical Informatics is still relatively young.

Computer-based patient record:

The patient record used in a clinical setting generally contains the notes of clinicians and other care providers which are often supplemented with data from other sources for example biochemical & pathological reports, X-rays, ultrasound, lung function, endoscopy etc. With the exception of electrocardiograms, some images, or drawings, the majority of information in the paper-based record involves the alphanumeric data. People have tried to develop the Computer-based Patient Records (CPR) for more than 25 years, firstly in a hospital setting and focused on those that were relatively easy to structure: diagnosis & laboratory test results based, and medication data. History of patient and the physical examination proved to be far more difficult to collect in a structured format. There has been observed reluctance in the clinicians as well the variation in them in phrasing the data. They feel probably this mode of entering the data a time-consuming and unfriendly to the patients.

 Factors towards recent increase of Clinical Informatics:





Patients particulars

History (Personal, Present, Past, Drug, Family etc)

Physical examination (General, Systemic, Local etc)

Patients' Lab supported information  (Investigations on body fluids, X‑ray, ECG, USG, Scan)


Rules for the documentation of patient data in computers:



Goals: Help people maintain good health through prevention and treatment structure and use of medical data.

 Purpose: Organize / integrate data and develop relation among problems. Missing of details can be avoided.
