Health Informatics - Emergence of Health Information Technology
Each century is observing and inheriting new technology in health care information as and when it gets invaded and put into use. Health informatics has become popular by creating a connection between three different elements. Patient, health professional and information store are bound together to be revisited in future whenever the need arises. The word is a combination of two different concepts- health and information technology. Creating a link between two has become significant and vital in current era. The health information of the individual is stored using IT devices so that it can be retrieved at a later date when required. One of the important factors is analysis, evaluation and customization of health information system that strengthens the medical expert-patient relationship. This follows from the fact to make use of guidelines and ethics needed in medical field. A foolproof system of privacy and confidence needs to be developed and implemented. Thus, it is the mere exchange of health information in a systematic manner through the process of a set of medical standards such as HL7. HL7 is a health care IT standard which every vendor has to follow globally for interoperability. The main objective is to achieve the most apt and suitable health care deliverance and execution system. For the purpose, the health professionals need to be trained in the usage and applicability of most advanced IT features and functions. This may require gaining much of practical knowledge, experience and funding. At the same time, proper and prudent medical and clinical decision support system is a major requirement. M-health and e-health are equivalently needed to achieve the goals of this discipline. Health informatics is gaining status with increasing use of information technology and communication in health care. This promotes and allows a long-lasting and ever-growing bond between the patient and specialist. Confidence- building and privacy should be maintained as much as possible.
