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.
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.
Telehealth is the distribution of health-related services and information via electronic information and telecommunication technologies. It allows long-distance patient and clinician contact, care, advice, reminders, education, intervention, monitoring, and remote admissions. Telemedicine is sometimes used as a synonym, or is used in a more limited sense to describe remote clinical services, such as diagnosis and monitoring. When rural settings, lack of transport, a lack of mobility, conditions due to outbreaks, epidemics or pandemics, decreased funding, or a lack of staff restrict access to care, telehealth may bridge the gap as well as provide distance-learning; meetings, supervision, and presentations between practitioners; online information and health data management and healthcare system integration. Telehealth could include two clinicians discussing a case over video conference; a robotic surgery occurring through remote access; physical therapy done via digital monitoring instruments, live feed and application combinations; tests being forwarded between facilities for interpretation by a higher specialist; home monitoring through continuous sending of patient health data; client to practitioner online conference; or even videophone interpretation during a consult.
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.
A Regional Health Information Organization, also called a Health Information Exchange Organization, is a multistakeholder organization created to facilitate a health information exchange (HIE) – the transfer of healthcare information electronically across organizations – among stakeholders of that region's healthcare system. The ultimate objective is to improve the safety, quality, and efficiency of healthcare as well as access to healthcare through the efficient application of health information technology. RHIOs are also intended to support secondary use of clinical data for research as well as institution/provider quality assessment and improvement. RHIO stakeholders include smaller clinics, hospitals, medical societies, major employers and payers.
The eHealth Exchange, formerly known as the Nationwide Health Information Network, is an initiative for the exchange of healthcare information. It was developed under the auspices of the U.S. Office of the National Coordinator for Health Information Technology (ONC), and now managed by a non-profit industry coalition called Sequoia Project. The exchange is a web-services based series of specifications designed to securely exchange healthcare related data. The NwHIN is related to the Direct Project which uses a secure email-based approach. One of the latest goals is to increase the amount of onboarding information about the NwHIN to prospective vendors of health care systems.
In 2004, the Agency for Healthcare Research and Quality of the United States Department of Health and Human Services created the AHRQ National Resource Center for Health Information Technology to support over 125 federal grants and contracts that are demonstrating the value and implementation of information technology in health care.
The medical home, also known as the patient-centered medical home (PCMH), is a team-based health care delivery model led by a health care provider to provide comprehensive and continuous medical care to patients with a goal to obtain maximal health outcomes. It is described in the "Joint Principles" as "an approach to providing comprehensive primary care for children, youth and adults."
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 Office of the National Coordinator for Health Information Technology (ONC) is a staff division of the Office of the Secretary, within the U.S. Department of Health and Human Services. ONC leads national health IT efforts. It is charged as the principal federal entity to coordinate nationwide efforts to implement the use of advanced health information technology and the electronic exchange of health information.
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 Chesapeake Regional Information System for our Patients (CRISP) is a nonprofit organization created to function as Maryland's state-designated health information exchange (HIE), by the Maryland Health Care Commission. CRISP currently serves as the HIE for Maryland and the District of Columbia. CRISP is advised by a wide range of stakeholders who are responsible for healthcare throughout the region.
Informatics Corporation of America (ICA) is a privately held health information technology organization headquartered in Nashville, Tennessee. It serves integrated delivery systems (IDNs), health information exchanges (HIEs), individual hospitals, Independent Practice Associations (IPAs), and Regional Health Information Systems (RHIOs). In 2000, some of Vanderbilt University Medical Center's (VUMC) practicing physicians teamed up with informatics professionals to develop two complementary software applications—dubbed StarChart and StarPanel—to aggregate and organise medical data, and to improve communication and clinical decision-making within a single interface. This technology has allowed VUMC to improve efficiency and communication processes in order to deliver cohesive care across the medical center and its affiliated clinics and physicians' practices.
Clinical point of care (POC) is the point in time when clinicians deliver healthcare products and services to patients at the time of care.
The Health Information Technology for Economic and Clinical Health Act, abbreviated the HITECH Act, was enacted under Title XIII of the American Recovery and Reinvestment Act of 2009. Under the HITECH Act, the United States Department of Health and Human Services resolved to spend $25.9 billion to promote and expand the adoption of health information technology. The Washington Post reported the inclusion of "as much as $36.5 billion in spending to create a nationwide network of electronic health records." At the time it was enacted, it was considered "the most important piece of health care legislation to be passed in the last 20 to 30 years" and the "foundation for health care reform."
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.
HealthShare Exchange (HSX) is a membership-dues-supported nonprofit health information exchange formed in 2009 and incorporated in 2012 by Greater Philadelphia's hospitals, health systems, and healthcare insurers.[1][2] It links the electronic medical record (EMR) systems of different hospital health systems and other healthcare providers — and the claims data of healthcare insurers — to make this information accessible at inpatient and outpatient points of care (including medical practice offices) and for care management. HSX services provide recent clinical care information, and alert providers and health plans to care events.[2] Health information exchange makes patient care more informed and coordinated, and reduces unnecessary care and readmissions. HSX serves the greater Delaware Valley region, including southeastern Pennsylvania and southern New Jersey.[2]
HIE of One is a free software project developing tools for patients to manage their own health records. HIE stands for Health Information Exchange, an electronic network for sharing health information across different organizations, hospitals, providers, and patients. This is one of a growing number of tools for encrypted data exchange within the healthcare sphere.
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.
