health informatics health informatics health informatics is the field of science and engineering that aims at developing methods and technologies for the acquisition, processing, and study of patient data, which can come from different sources and modalities, such as electronic health records, diagnostic test results, medical scans. the health domain provides an extremely wide variety of problems that can be tackled using computational techniques. medical informatics introduces information processing concepts and machinery to the domain of medicine. health informatics is a spectrum of multidisciplinary fields that includes study of the design, development and application of computational innovations to improve health care. the disciplines involved combines medicine fields with computing fields, in particular computer engineering, software engineering, information engineering, bioinformatics, bio-inspired computing, theoretical computer science, information systems, data science, information technology, autonomic computing, and behavior informatics. in academic institutions, medical informatics research focus on applications of artificial intelligence in healthcare and designing medical devices based on embedded systems. in some countries term informatics is also used in the context of applying library science to data management in hospitals. 'clinical informaticians' are qualified health and social care professionals and 'clinical informatics' is a subspecialty within several medical specialties. subject areas within health informatics an example of an application of informatics in medicine is bioimage informatics. jan van bemmel has described medical informatics as the theoretical and practical aspects of information processing and communication based on knowledge and experience derived from processes in medicine and health care.an example of how the 2d fourier transform can be used to remove unwanted information from an x-ray scan. the faculty of clinical informatics has identified six high level domains of core competency for clinical informaticians: health and wellbeing in practice information technologies and systems working with data and analytical methods enabling human and organizational change decision making leading informatics teams and projects. tools to support practitioners clinical informaticians use their knowledge of patient care combined with their understanding of informatics concepts, methods, and health informatics tools to: assess information and knowledge needs of health care professionals, patients and their families. characterize, evaluate, and refine clinical processes, develop, implement, and refine clinical decision support systems, and lead or participate in the procurement, customization, development, implementation, management, evaluation, and continuous improvement of clinical information systems. clinicians collaborate with other health care and information technology professionals to develop health informatics tools which promote patient care that is safe, efficient, effective, timely, patient-centered, and equitable. many clinical informaticists are also computer scientists. the frustration experiences by many practitioners is described in "why doctors hate their computers" telehealth and telemedicine
