Health informatics is the study and implementation of computer structures and algorithms to improve communication, understanding, and management of medical information. It can be viewed as branch of engineering and applied science.
An electronic health record (EHR) is the systematized collection of patient and population electronically stored health information in a digital format. These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHRs may include a range of data, including demographics, medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal statistics like age and weight, and billing information.
A personal health record (PHR) is a health record where health data and other information related to the care of a patient is maintained by the patient. This stands in contrast to the more widely used electronic medical record, which is operated by institutions and contains data entered by clinicians to support insurance claims. The intention of a PHR is to provide a complete and accurate summary of an individual's medical history which is accessible online. The health data on a PHR might include patient-reported outcome data, lab results, and data from devices such as wireless electronic weighing scales or from a smartphone.
Cambridge University Hospitals NHS Foundation Trust is a British public sector healthcare provider located in Cambridge, England. It was established on 4 November 1992 as Addenbrooke's National Health Service Trust, and authorised as an NHS foundation trust under its current name on 1 July 2004.
Health information exchange (HIE) is the mobilization of health care information electronically across organizations within a region, community or hospital system. Participants in data exchange are called in the aggregate Health Information Networks (HIN). In practice, the term HIE may also refer to the health information organization (HIO) that facilitates the exchange.
The Certification Commission for Health Information Technology (CCHIT) was an independent, 501(c)(3) nonprofit organization with the public mission of accelerating adoption of robust, interoperable health information technology in the United States. The Commission certified electronic health record technology (EHR) from 2006 until 2014. It was approved by the Office of the National Coordinator for Health Information Technology (ONC) of the U.S. Department of Health and Human Services (HHS) as an Authorized Testing and Certification Body (ONC-ATCB). The CCHIT Certified program is an independently developed certification that includes a rigorous inspection of an EHR's integrated functionality, interoperability and security using criteria developed by CCHIT's broadly representative, expert work groups. These products may also be certified in the ONC-ATCB certification program.
Health information management (HIM) is information management applied to health and health care. It is the practice of analyzing and protecting digital and traditional medical information vital to providing quality patient care. With the widespread computerization of health records, traditional (paper-based) records are being replaced with electronic health records (EHRs). The tools of health informatics and health information technology are continually improving to bring greater efficiency to information management in the health care sector.
Patient portals are healthcare-related online applications that allow patients to interact and communicate with their healthcare providers, such as physicians and hospitals. Typically, portal services are available on the Internet at all hours of the day and night. Some patient portal applications exist as stand-alone web sites and sell their services to healthcare providers. Other portal applications are integrated into the existing web site of a healthcare provider. Still others are modules added onto an existing electronic medical record (EMR) system. What all of these services share is the ability of patients to interact with their medical information via the Internet. Currently, the lines between an EMR, a personal health record, and a patient portal are blurring. For example, Intuit Health and Microsoft HealthVault describe themselves as personal health records (PHRs), but they can interface with EMRs and communicate through the Continuity of Care Record standard, displaying patient data on the Internet so it can be viewed through a patient portal.
The emerging field of Health administration informatics is concerned with the evaluation, acquisition, implementation and day-to-day operation of information technology systems in support of all administration and clinical functions within the health care industry. The closely related field of biomedical informatics is primarily focused on the use of information systems for acquisition and application of patients' medical data, whereas nursing informatics deals with the delivery, administration and evaluation of patient care and disease prevention. What remains unclear, however, is how this emerging discipline should relate to the myriad of previously existing sub specializations within the broad umbrella of health informatics - including clinical informatics, bioinformatics and healthcare management informatics - particularly in light of the proposed "fundamental theorem" of biomedical informatics posed by Friedman in early 2009.
Health information technology (HIT) is health technology, particularly information technology, applied to health and health care. It supports health information management across computerized systems and the secure exchange of health information between consumers, providers, payers, and quality monitors. Based on a 2008 report on a small series of studies conducted at four sites that provide ambulatory care – three U.S. medical centers and one in the Netherlands, the use of electronic health records (EHRs) was viewed as the most promising tool for improving the overall quality, safety and efficiency of the health delivery system.
The Veterans Health Information Systems and Technology Architecture (VISTA) is the system of record for the clinical, administrative and financial operations of the Veterans Health Administration VISTA consists of over 180 clinical, financial, and administrative applications integrated within a single shared lifelong database (figure 1).
The World Health Imaging, Telemedicine and Informatics Alliance (WHITIA) is a non-profit global health technology and social venture established in 2006 by affiliates of Northwestern University near Chicago, Illinois. WHITIA was formerly known as the World Health Imaging Alliance (WHIA) until it formally expanded its scope in June 2009.
The Fast Healthcare Interoperability Resources standard is a set of rules and specifications for exchanging electronic health care data. It is designed to be flexible and adaptable, so that it can be used in a wide range of settings and with different health care information systems. The goal of FHIR is to enable the seamless and secure exchange of health care information, so that patients can receive the best possible care. The standard describes data formats and elements and an application programming interface (API) for exchanging electronic health records (EHR). The standard was created by the Health Level Seven International (HL7) health-care standards organization.
Digital health is a discipline that includes digital care programs, technologies with health, healthcare, living, and society to enhance the efficiency of healthcare delivery and to make medicine more personalized and precise. It uses information and communication technologies to facilitate understanding of health problems and challenges faced by people receiving medical treatment and social prescribing in more personalised and precise ways. The definitions of digital health and its remits overlap in many ways with those of health and medical informatics.
The adoption of electronic medical records refers to the recent shift from paper-based medical records to electronic health records (EHRs) in hospitals. The move to electronic medical records is becoming increasingly prevalent in health care delivery systems in the United States, with more than 80% of hospitals adopting some form of EHR system by November 2017.
InterSystems HealthShare is a comprehensive healthcare informatics platform designed to serve hospitals, Integrated Delivery Networks (IDNs), and regional and national Health Information Exchanges (HIEs).
Enterprise imaging has been defined as "a set of strategies, initiatives, and workflows implemented across a healthcare enterprise to consistently and optimally capture, index, manage, store, distribute, view, exchange, and analyze all clinical imaging and multimedia content to enhance the electronic health record". The concepts of enterprise imaging are elucidated in a series of papers by members of the HIMSS-SIIM Enterprise Imaging Workgroup.
The Global Digital Exemplar (GDE) programme is an NHS England initiative to achieve digital transformation in selected exemplar organisations and to create a knowledge sharing ecosystem to spread learning from these exemplars. The programme is to enable "digitally advanced" NHS trusts to share knowledge with other NHS trusts, specifically knowledge gained during the implementation of IT systems, and especially experience from introducing electronic health record (EHR) systems. The GDE project is expected to last two to three and a half years; with the most digitally advanced trusts on the shorter time scale.
Federal and state governments, insurance companies and other large medical institutions are heavily promoting the adoption of electronic health records. The US Congress included a formula of both incentives and penalties for EMR/EHR adoption versus continued use of paper records as part of the Health Information Technology for Economic and Clinical Health (HITECH) Act, enacted as part of the, American Recovery and Reinvestment Act of 2009.
Autonomous pharmacy is an approach to medication management that seeks to create a more automated and data-driven process for medication inventory and dispensing. The main concept behind autonomous pharmacy is to use technology in place of manual medication processes in order to help healthcare providers reduce medication errors, decrease costs and save staff time. Autonomous pharmacy may use a combination of hardware, software and technology-enabled services to allow pharmacists to more effectively manage medication dispersal.
