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.
The Department of Health and Social Care (DHSC) is a department of His Majesty's Government responsible for government policy on health and adult social care matters in England, along with a few elements of the same matters which are not otherwise devolved to the Scottish Government, Welsh Government or Northern Ireland Executive. It oversees the English National Health Service (NHS). The department is led by the secretary of state for health and social care with three ministers of state and three parliamentary under-secretaries of state.
A hospital information system (HIS) is an element of health informatics that focuses mainly on the administrational needs of hospitals. In many implementations, a HIS is a comprehensive, integrated information system designed to manage all the aspects of a hospital's operation, such as medical, administrative, financial, and legal issues and the corresponding processing of services. Hospital information system is also known as hospital management software (HMS) or hospital management system.
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.
NHS Digital is the trading name of the Health and Social Care Information Centre, which is the national provider of information, data and IT systems for commissioners, analysts and clinicians in health and social care in England, particularly those involved with the National Health Service of England. The organisation is an executive non-departmental public body of the Department of Health and Social Care.
Computerized physician order entry (CPOE), sometimes referred to as computerized provider order entry or computerized provider order management (CPOM), is a process of electronic entry of medical practitioner instructions for the treatment of patients under his or her care.
NHS Wales is the publicly-funded healthcare system in Wales, and one of the four systems which make up the National Health Service in the United Kingdom.
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.
The Clinical Practice Research Datalink (CPRD) is an observational and interventional research service that operates as part of the UK Department of Health. It is jointly funded by the National Institute for Health and Care Research(NIHR) and the Medicines and Healthcare products Regulatory Agency (MHRA). CPRD is working closely with the extensive primary care, topic specific and comprehensive NIHR research networks and with NHS Digital.
The NHS Connecting for Health (CFH) agency was part of the UK Department of Health and was formed on 1 April 2005, having replaced the former NHS Information Authority. It was part of the Department of Health Informatics Directorate, with the role to maintain and develop the NHS national IT infrastructure. It adopted the responsibility of delivering the NHS National Programme for IT (NPfIT), an initiative by the Department of Health to move the National Health Service (NHS) in England towards a single, centrally-mandated electronic care record for patients and to connect 30,000 general practitioners to 300 hospitals, providing secure and audited access to these records by authorised health professionals.
A clinical coder—also known as clinical coding officer, diagnostic coder, medical coder, or nosologist—is a health information professional whose main duties are to analyse clinical statements and assign standardized codes using a classification system. The Health data produced are an integral part of health information management, and are used by local and national governments, private healthcare organizations and international agencies for various purposes, including medical and health services research, epidemiological studies, health resource allocation, case mix management, public health programming, medical billing, and public education.
The National Health Service (NHS) (GC) is the publicly funded healthcare system in England, and one of the four National Health Service systems in the United Kingdom. It is the second largest single-payer healthcare system in the world after the Brazilian Sistema Único de Saúde. Primarily funded by the government from general taxation, and overseen by the Department of Health and Social Care, the NHS provides healthcare to all legal English residents and residents from other regions of the UK, with most services free at the point of use for most people. The NHS also conducts research through the National Institute for Health and Care Research (NIHR).
SystmOne is a centrally hosted clinical computer system developed by Horsforth-based The Phoenix Partnership (TPP). It is used by healthcare professionals in the UK predominantly in primary care. The system is being deployed as one of the accredited systems in the government's programme of modernising IT in the NHS.
Healthcare in Wales is mainly provided by the Welsh public health service, NHS Wales. NHS Wales provides healthcare to all permanent residents that is free at the point of need and paid for from general taxation. Health is a matter that is devolved, and considerable differences are now developing between the public healthcare systems in the different countries of the United Kingdom, collectively the National Health Service (NHS). Though the public system dominates healthcare provision, private health care and a wide variety of alternative and complementary treatments are available for those willing to pay.
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.
Medical image sharing is the electronic exchange of medical images between hospitals, physicians and patients. Rather than using traditional media, such as a CD or DVD, and either shipping it out or having patients carry it with them, technology now allows for the sharing of these images using the cloud. The primary format for images is DICOM. Typically, non-image data such as reports may be attached in standard formats like PDF during the sending process. Additionally, there are standards in the industry, such as IHE Cross Enterprise Document Sharing for Imaging (XDS-I), for managing the sharing of documents between healthcare enterprises. A typical architecture involved in setup is a locally installed server, which sits behind the firewall, allowing secure transmissions with outside facilities. In 2009, the Radiological Society of North America launched the "Image Share" project, with the goal of giving patients control of their imaging histories by allowing them to manage these records as they would online banking or shopping.
EMIS Health, formerly known as Egton Medical Information Systems, supplies electronic patient record systems and software used in primary care, acute care and community pharmacy in the United Kingdom. The company is based in Leeds. It claims that more than half of GP practices across the UK use EMIS Health software and holds number one or two market positions in its main markets. In June 2022 the company was acquired by Bordeaux UK Holdings II Limited, an affiliate of UnitedHealth’s Optum business for a 49% premium on EMIS’s closing share price.
A patient tracking system allows a healthcare provider to log and monitor the progress of a person through the provision of care during their stay there. Such systems are part of an overall information system and may interact with the person's electronic health record, where information specific to the person is stored, the system used by radiology departments to track patients as well as the system storing medical images, the pathology laboratory information management system, as well as patient check-in and check-out systems.
In 2005 the National Health Service (NHS) in the United Kingdom began deployment of electronic health record systems in NHS Trusts. The goal was to have all patients with a centralized electronic health record by 2010. Lorenzo patient record systems were adopted in a number of NHS trusts. While many hospitals acquired electronic patient records systems in this process, there was no national healthcare information exchange. Ultimately, the program was dismantled after a cost to the UK taxpayer was over $24 billion, and is considered one of the most expensive healthcare IT failures.
Clinical data standards are used to store and communicate information related to healthcare so that its meaning is unambiguous. They are used in clinical practice, in activity analysis and finding, and in research and development.
