Medical informatics involves the application of information technology to healthcare for solving problems, making informed decisions, and delivering the best quality care services. Advances in health informatics deal with resources, devices, and methods needed for optimizing the acquisition, storage, and use of patient medical records. Health information strategies offer patients, healthcare professionals, and insurance companies electronic access to patient data for patients themselves. Nursing informatics acquires, studies, and manages health data with the help of technological systems that enable physicians to provide better care. Health informatics strategies allow the exchange of information between different organizations and systems through interoperability.
