Health care informatics combines the fields of information technology and health to develop the systems required to administer the expansion of information, advance clinical work flow, and improve the security of the health care system. It involves the integration of information science, computer technology, and medicine to collect, organize, and secure information systems and health–related data. The extraordinary explosion of medical knowledge, technologies, and ground-breaking drugs may vastly improve health care delivery to consumers, and keeping the information related to these advancements organized and accessible is key.
Health care informatics utilizes computer hardware, specialized software, and communication devices to form complex computer networks to collect, analyze, and transmit medical processes. The tools for creating health information systems are not limited just to information technology. These systems should also allow for the assimilation of clinical directives, understanding of formal medical jargon, storage of data, and transmission of clear communication. Medical informatics can be applied in all types of health environments, including primary care, general practice, hospital care, and rehabilitation. It is also inclusive of many of the specialties within the health care field.
Information systems may used to create greater operating efficiencies in three basic functions of health care: clinical, administrative, and financial. For example, health care informatics is pivotal in the movement to cut costs and enhance patient care by implementing a standardized system for electronic medical records. It is also a key to expanding the development health information systems for billing, clinical research, client scheduling, and the exchange of medical information.
Physicians can avail themselves of the growing knowledge base and make better decisions bolstered by computer software called clinical decision support systems (CDSS). Other computer systems, called electronic prescribing systems, eliminate the need for hand-written prescriptions and minimize errors. Informatics also allow for data mining to determine the effectiveness of drugs. This may reduce the cost of treatments, lessen mistakes, and help further advancements in the quality of care.
One of the major objectives of health care informatics is to formulate a standard approach for health care internationally. The idea is for researchers, providers, and patients to benefit from the informatics tools, techniques, concepts, and protocols that transform health care delivery, and to promote best practices in the health care field. As a result of evolving and complex legal issues related to information technology and health-related fields, health care informatics is also important in health law as it relates to ethical, operational, and privacy concerns.
