Concepts and definitions[ edit ] Health information technology HIT is "the application of information processing involving both computer hardware and software that deals with the storage, retrieval, sharing, and use of health care information, health dataand knowledge for communication and decision making". However, a strict definition is elusive; "technology" can refer to material objects of use to humanity, such as machines, hardware or utensils, but can also encompass broader themes, including systems, methods of organization, and techniques. For HIT, technology represents computers and communications attributes that can be networked to build systems for moving health information. Informatics is yet another integral aspect of HIT.
The electronic health record EHR is a more longitudinal collection of the electronic health information of individual patients or populations. The EMR, in contrast, is the patient record created by providers for specific encounters in hospitals and ambulatory environments, and which can serve as a data source for an EHR.
Electronic records may help with the standardization of forms, terminology and data input. If the ability to exchange records between different EMR systems were perfected "interoperability"  it would facilitate the co-ordination of health care delivery in non-affiliated health care facilities.
In addition, data from an electronic system can be used anonymously for statistical reporting in matters such as quality improvement, resource management and public health communicable disease surveillance.
The data can then be efficiently used for epidemiological analysis, including de-identified data at the National level.
This system greatly reduced the number of missed critical opportunities. However, other research traditions see the EHR as a contextualised artifact within a socio-technical system. For example, actor-network theory would see the EHR as an actant in a network,  while research in computer supported cooperative work CSCW sees the EHR as a tool supporting particular work.
Several possible advantages to EHRs over paper records have been proposed, but there is debate about the degree to which these are achieved in practice. An article in a trade journal suggests that since anyone using an EMR can view the patient's full chart, it cuts down on guessing histories, seeing multiple specialists, smooths transitions between care settings, and may allow better care in emergency situations.
Congressional Budget Office concluded that the cost savings may occur only in large integrated institutions like Kaiser Permanente, and not in small physician offices.
They challenged the Rand Corporation 's estimates of savings. Even though the use of health IT could generate cost savings for the health system at large that might offset the EHR's cost, many physicians might not be able to reduce their office expenses or increase their revenue sufficiently to pay for it.
For example, the use of health IT could reduce the number of duplicated diagnostic tests. However, that improvement in efficiency would be unlikely to increase the income of many physicians.
A key reason, aside from initial costs and lost productivity during EMR implementation, is lack of efficiency and usability of EMRs currently available. National Institute of Standards and Technology of the Department of Commerce studied usability in and lists a number of specific issues that have been reported by health care workers.
According to a survey by Physicians Practice, Mobile devices are increasingly able to sync up with electronic health record systems thus allowing physicians to access patient records from remote locations.
Most devices are extensions of desk-top EHR systems, using a variety of software to communicate and access files remotely. The advantages of instant access to patient records at any time and any place are clear, but bring a host of security concerns. As mobile systems become more prevalent, practices will need comprehensive policies that govern security measures and patient privacy regulations.
Staff and patients will need to engage with various devices throughout a patient's stay and charting workflow. Computers, laptops, all-in-one computers, tablets, mouse, keyboards and monitors are all hardware devices that may be utilized.
Other considerations will include supporting work surfaces and equipment, wall desks or articulating arms for end users to work on. Another important factor is how all these devices will be physically secured and how they will be charged that staff can always utilize the devices for EHR charting when needed.
The success of eHealth interventions is largely dependent on the ability of the adopter to fully understand workflow and anticipate potential clinical processes prior to implementations. Failure to do so can create costly and time-consuming interruptions to service delivery.
Joint Commissionthe organization that accredits American hospitals to provide healthcare services, states that "As health information technology HIT and 'converging technologies'—the interrelationship between medical devices and HIT—are increasingly adopted by health care organizations, users must be mindful of the safety risks and preventable adverse events that these implementations can create or perpetuate.
Technology-related adverse events can be associated with all components of a comprehensive technology system and may involve errors of either commission or omission. The National Health Service NHS in the UK reports specific examples of potential and actual EHR-caused unintended consequences in their document on the management of clinical risk relating to the deployment and use of health software.
In the memo FDA also notes the "absence of mandatory reporting enforcement of H-IT safety issues limits the numbers of medical device reports MDRs and impedes a more comprehensive understanding of the actual problems and implications. Issues of privacy and security in such a model have been of concern.
Threats to health care information can be categorized under three headings: Human threats, such as employees or hackers Natural and environmental threats, such as earthquakes, hurricanes and fires. Technology failures, such as a system crashing These threats can either be internal, external, intentional and unintentional.Global E-Cigarette Market Growing Health Awareness, Advancement in Electronic Device Technology, Smoke & Ash Less Vaping - Research and Markets.
Medical records and health information technicians, commonly referred to as health information technicians, organize and manage health information data. They ensure that the information maintains its quality, accuracy, accessibility, and security in both paper files and electronic systems.
They use. Health information technology (HIT) refers to the framework used to manage health information, and the exchange of health information in a digital format. Professionals who work in HIT are focused on the technical side of managing health information, working with software and hardware used to manage and store patient data.
Nov 17, · Use health communication strategies and health information technology to improve population health outcomes and health care quality, and to achieve health equity.
Overview Ideas about health and behaviors are shaped by the communication, . Adoption rates of the electronic health record have increased substantially, yet significant progress is still needed to reach a patient-centered, fully integrated system of health care.
The sheer amount of data most providers and healthcare systems generate is staggering and much is only being used for quality programs that health plans mandate. Health IT (health information technology) is the area of IT involving the design, development, creation, use and maintenance of information systems for the healthcare industry.
Automated and interoperable healthcare information systems will continue to improve medical care and public health, lower.
