A picture archiving and communication system (PACS) is a medical imaging technology which provides economical storage and convenient access to images from multiple modalities. Electronic images and reports are transmitted digitally via PACS; this eliminates the need to manually file, retrieve, or transport film jackets, the folders used to store and protect X-ray film. The universal format for PACS image storage and transfer is DICOM. Non-image data, such as scanned documents, may be incorporated using consumer industry standard formats like PDF, once encapsulated in DICOM. A PACS consists of four major components: The imaging modalities such as X-ray plain film (PF), computed tomography (CT) and magnetic resonance imaging (MRI), a secured network for the transmission of patient information, workstations for interpreting and reviewing images, and archives for the storage and retrieval of images and reports. Combined with available and emerging web technology, PACS has the ability to deliver timely and efficient access to images, interpretations, and related data. PACS reduces the physical and time barriers associated with traditional film-based image retrieval, distribution, and display.
Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, tertiary care, and public health.
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 a branch of engineering and applied science.
Health Level Seven, abbreviated to HL7, is a range of global standards for the transfer of clinical and administrative health data between applications with the aim to improve patient outcomes and health system performance. The HL7 standards focus on the application layer, which is "layer 7" in the Open Systems Interconnection model. The standards are produced by Health Level Seven International, an international standards organization, and are adopted by other standards issuing bodies such as American National Standards Institute and International Organization for Standardization. There are a range of primary standards that are commonly used across the industry, as well as secondary standards which are less frequently adopted.
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.
The Healthcare Information and Management Systems Society (HIMSS) is an American not-for-profit organization dedicated to improving health care in quality, safety, cost-effectiveness and access through the best use of information technology and management systems. It was founded in 1961 as the Hospital Management Systems Society. It is now headquartered in Chicago, Illinois. The society has more than 100,000 individuals, 480 provider organizations, 470 non-profit partners and 650 health services organizations. HIMSS is a US 501(c)6 organization.
A clinical decision support system (CDSS) is a health information technology that provides clinicians, staff, patients, and other individuals with knowledge and person-specific information to help health and health care. CDSS encompasses a variety of tools to enhance decision-making in the clinical workflow. These tools include computerized alerts and reminders to care providers and patients, clinical guidelines, condition-specific order sets, focused patient data reports and summaries, documentation templates, diagnostic support, and contextually relevant reference information, among other tools. CDSSs constitute a major topic in artificial intelligence in medicine.
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.
The European Committee for Standardization (CEN) Standard Architecture for Healthcare Information Systems, Health Informatics Service Architecture or HISA is a standard that provides guidance on the development of modular open information technology (IT) systems in the healthcare sector. Broadly, architecture standards outline frameworks which can be used in the development of consistent, coherent applications, databases and workstations. This is done through the definition of hardware and software construction requirements and outlining of protocols for communications. The HISA standard provides a formal standard for a service-oriented architecture (SOA), specific for the requirements of health services, based on the principles of Open Distributed Processing. The HISA standard evolved from previous work on healthcare information systems architecture commenced by Reseau d’Information et de Communication Hospitalier Europeen (RICHE) in 1989, and subsequently built upon by a number of organizations across Europe.
Normalization process theory (NPT) is a sociological theory, generally used in the fields of science and technology studies (STS), implementation research, and healthcare system research. The theory deals with the adoption of technological and organizational innovations into systems, recent studies have utilized this theory in evaluating new practices in social care and education settings. It was developed out of the normalization process model.
The Zambia Electronic Perinatal Record System (ZEPRS) is an Electronic Medical Record (EMR) system used by public obstetric clinics and a hospital in Lusaka, Zambia.
Outcomes research is a branch of public health research which studies the end results of the structure and processes of the health care system on the health and well-being of patients and populations. According to one medical outcomes and guidelines source book - 1996, Outcomes research includes health services research that focuses on identifying variations in medical procedures and associated health outcomes. Though listed as a synonym for the National Library of Medicine MeSH term "Outcome Assessment ", outcomes research may refer to both health services research and healthcare outcomes assessment, which aims at health technology assessment, decision making, and policy analysis through systematic evaluation of quality of care, access, and effectiveness.
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).

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.
My Health Record (MHR) is the national digital health record platform for Australia, and is managed by the Australian Digital Health Agency. It was originally established as the Personally Controlled Electronic Health Record (PCEHR), a shared electronic health summary set up by the Australian government with implementation overseen by the National Electronic Health Transition Authority (NEHTA). The purpose of the MHR is to provide a secure electronic summary of people's medical history which will eventually include information such as current medications, adverse drug reactions, allergies and immunisation history in an easily accessible format. This MHR is stored in a network of connected systems with the ability to improve the sharing of information amongst health care providers to improve patient outcomes no matter where in Australia a patient presents for treatment. PCEHR was an opt-in system with a unique individual healthcare identifier (IHI) being assigned to participants and the option of masking and limiting information available for viewing controlled by the patient or a nominated representative; MHR uses an opt-out system.
