Like other IT training specialties, there are Informatics certifications available to help informatics professionals stand out and be recognized. The CIIP certification requires documented experience working in Imaging Informatics, formal testing and is a limited time credential requiring renewal every five years. The exam tests for a combination of IT technical knowledge, clinical understanding, and project management experience thought to represent the typical workload of a PACS administrator or other radiology IT clinical support role.
Certifications are widely requested by employers in health informatics, and overall the demand for certified informatics workers in the United States is outstripping supply. In , a consortium of health informatics trainers composed of MEASURE Evaluation, Public Health Foundation India, University of Pretoria, Kenyatta University, and the University of Ghana identified the following areas of knowledge as a curriculum for the digital health workforce, especially in low- and middle-income countries: clinical decision support; telehealth ; privacy, security, and confidentiality; workflow process improvement; technology, people, and processes; process engineering; quality process improvement and health information technology; computer hardware; software; databases; data warehousing; information networks; information systems; information exchange; data analytics; and usability methods.
The book describes the path taken as 'early development of health informatics was unorganized and idiosyncratic'. In the early s, it was prompted by those involved in NHS finance and only in the early s did solutions including those in pathology , radiotherapy , immunization , and primary care emerge. Many of these solutions, even in the early s were developed in-house by pioneers in the field to meet their own requirements. In part, this was due to some areas of health services for example the immunization and vaccination of children still being provided by Local Authorities.
Interesting, this is a situation which the coalition government proposes broadly to return to in the strategy Equity and Excellence: Liberating the NHS July ; stating:. They will have increased control over their own care records. These types of statements present a significant opportunity for health informaticians to come out of the back-office and take up a front-line role in supporting clinical practice, and the business of care delivery. FEDIP is the Federation for Informatics Professionals in Health and Social Care, a collaboration between the leading professional bodies in health and care informatics supporting the development of the informatics profession.
Since , the Buenos Aires Biomedical Informatics Group, a nonprofit group, represents the interests of a broad range of clinical and non-clinical professionals working within the Health Informatics sphere.
Its purposes are:. The Argentinian health system is heterogeneous in its function, and because of that the informatics developments show a heterogeneous stage. Many private Health Care center have developed systems, such as the Hospital Aleman of Buenos Aires, or the Hospital Italiano de Buenos Aires that also has a residence program for health informatics. The first applications of computers to medicine and healthcare in Brazil started around , with the installation of the first mainframes in public university hospitals, and the use of programmable calculators in scientific research applications.
In the s, several Digital Corporation and Hewlett Packard minicomputers were acquired for public and Armed Forces hospitals, and more intensively used for intensive-care unit , cardiology diagnostics, patient monitoring and other applications. In the early s, with the arrival of cheaper microcomputers , a great upsurge of computer applications in health ensued, and in the Brazilian Society of Health Informatics was founded, the first Brazilian Congress of Health Informatics was held, and the first Brazilian Journal of Health Informatics was published.
In Brazil, two universities are pioneers in teaching and research in Medical Informatics, both the University of Sao Paulo and the Federal University of Sao Paulo offer undergraduate programs highly qualified in the area as well as extensive graduate programs MSc and PhD. Health Informatics projects in Canada are implemented provincially, with different provinces creating different systems. A national, federally funded, not-for-profit organization called Canada Health Infoway was created in to foster the development and adoption of electronic health records across Canada.
In , President George W. The mission of this office is widespread adoption of interoperable electronic health records EHRs in the US within 10 years. See quality improvement organizations for more information on federal initiatives in this area. The program is designed to provide specific Health Informatics education, and is the only program in the country with a Health Informatics Lab.
Loeser on May 10, with the first Health Informatics degree. Department of Health and Human Services to develop a set of standards for electronic health records EHR and supporting networks, and certify vendors who meet them. Harvard Medical School added a department of biomedical informatics in The European Union's Member States are committed to sharing their best practices and experiences to create a European eHealth Area, thereby improving access to and quality health care at the same time as stimulating growth in a promising new industrial sector. Work on this initiative involves a collaborative approach among several parts of the Commission services.
There are different models of health informatics delivery in each of the home countries England, Scotland, Northern Ireland and Wales but some bodies like UKCHIP  see below operate for those 'in and for' all the home countries and beyond. The various specific technical solutions were required to connect securely with the NHS 'Spine', a system designed to broker data between different systems and care settings.
NPfIT fell significantly behind schedule and its scope and design were being revised in real time, exacerbated by media and political lambasting of the Programme's spend past and projected against the proposed budget. This initiative provided little in the way of innovative thinking, primarily re-stating existing strategies within the proposed new context of the Coalition's vision for the NHS. The degree of computerization in NHS secondary care was quite high before NPfIT, and the programme stagnated further development of the install base — the original NPfIT regional approach provided neither a single, nationwide solution nor local health community agility or autonomy to purchase systems, but instead tried to deal with a hinterland in the middle.
Almost all general practices in England and Wales are computerized under the GP Systems of Choice GPSoC  programme, and patients have relatively extensive computerized primary care clinical records. System choice is the responsibility of individual general practices and while there is no single, standardized GP system, GPSoC sets relatively rigid minimum standards of performance and functionality for vendors to adhere to.
Interoperation between primary and secondary care systems is rather primitive. It is hoped that a focus on interworking for interfacing and integration standards will stimulate synergy between primary and secondary care in sharing necessary information to support the care of individuals.
Notable successes to date are in the electronic requesting and viewing of test results, and in some areas, GPs have access to digital x-ray images from secondary care systems. Scotland has an approach to the central connection underway which is more advanced than the English one in some ways. GPASS was accepted in It has been provided free to all GPs in Scotland but has developed poorly.
Wales has a dedicated Health Informatics function that supports NHS Wales in leading on the new integrated digital information services and promoting Health Informatics as a career. In the Netherlands, health informatics is currently a priority for research and implementation. Another stream of research currently focuses on aspects of "big data" in health information systems. For background information on data-related aspects in health informatics see, e. It represents the interests of a broad range of clinical and non-clinical professionals working within the health informatics sphere through a commitment to quality, standards and ethical practice.
Nursing informaticians were the driving force behind the formation of HISA, which is now a company limited by guarantee of the members. The membership comes from across the informatics spectrum that is from students to corporate affiliates. After 20 years, China performed a successful transition from its planned economy to a socialist market economy. Along this change, China's healthcare system also experienced a significant reform to follow and adapt to this historical revolution. Before the s, the entire healthcare costs were covered in central government annual budget.
Since that, the construct of healthcare-expended supporters started to change gradually. On the other hand, by , up to , healthcare facilities were recorded in statistic summary of MoH, and an average of 2. Along with the development of information technology since the s, healthcare providers realized that the information could generate significant benefits to improve their services by computerized cases and data, for instance of gaining the information for directing patient care and assessing the best patient care for specific clinical conditions.
Therefore, substantial resources were collected to build China's own health informatics system. Most of these resources were arranged to construct hospital information system HIS , which was aimed to minimize unnecessary waste and repetition, subsequently to promote the efficiency and quality-control of healthcare. China has four tiers in its healthcare system. The first tier is street health and workplace clinics and these are cheaper than hospitals in terms of medical billing and act as prevention centers.
The second tier is district and enterprise hospitals along with specialist clinics and these provide the second level of care. The third tier is provisional and municipal general hospitals and teaching hospitals which provided the third level of care. In a tier of its own is the national hospitals which are governed by the Ministry of Health. China has been greatly improving its health informatics since it finally opened its doors to the outside world and joined the World Trade Organization WTO.
In , it was reported that China had , medical institutions and the majority of those were clinics. The reason for that is that clinics are prevention centers and Chinese people like using traditional Chinese medicine as opposed to Western medicine and it usually works for the minor cases. China has also been improving its higher education in regards to health informatics.
At the end of , there were 77 medical universities and medical colleges. There were 48 university medical colleges which offered bachelor, master, and doctorate degrees in medicine. There were 21 higher medical specialty institutions that offered diploma degrees so in total, there were higher medical and educational institutions. Since joining the WTO, China has been working hard to improve its education system and bring it up to international standards.
China had been comparing itself to Korea's healthcare system and figuring out how it can better its own system. There was a study done that surveyed six hospitals in China that had HIS. The results were that doctors didn't use computers as much so it was concluded that it wasn't used as much for clinical practice than it was for administrative purposes. The survey asked if the hospitals created any websites and it was concluded that only four of them had created websites and that three had a third-party company create it for them and one was created by the hospital staff.
In conclusion, all of them agreed or strongly agreed that providing health information on the Internet should be utilized. Collected information at different times, by different participants or systems could frequently lead to issues of misunderstanding, dis-comparing or dis-exchanging. To design an issues-minor system, healthcare providers realized that certain standards were the basis for sharing information and interoperability, however a system lacking standards would be a large impediment to interfere the improvement of corresponding information systems.
Given that the standardization for health informatics depends on the authorities, standardization events must be involved with government and the subsequently relevant funding and supports were critical. In , the Ministry of Health released the Development Lay-out of National Health Informatics —  indicating the identification of standardization for health informatics which is 'combining adoption of international standards and development of national standards'. In China, the establishment of standardization was initially facilitated with the development of vocabulary, classification and coding , which is conducive to reserve and transmit information for premium management at national level.
Personal identifier codes were widely employed in different information systems, involving name, sex, nationality, family relationship, educational level and job occupation. However, these codes within different systems are inconsistent, when sharing between different regions. Considering this large quantity of vocabulary, classification and coding standards between different jurisdictions, the healthcare provider realized that using multiple systems could generate issues of resource wasting and a non-conflicting national level standard was beneficial and necessary.
The table above demonstrates details of this comparison which indicates certain domains of improvement for future revisions of EHR Standard in China. Meticulously, these deficiencies are listed in the following. This system has been deployed at all the sites of the authority 40 hospitals and clinics. It is used for up to 2 million transactions daily by 30, clinical staff.
The comprehensive records of 7 million patients are available on-line in the electronic patient record ePR , with data integrated from all sites. Since radiology image viewing has been added to the ePR, with radiography images from any HA site being available as part of the ePR. The Hong Kong Hospital Authority placed particular attention to the governance of clinical systems development, with input from hundreds of clinicians being incorporated through a structured process. The health informatics section in the Hospital Authority  has a close relationship with the information technology department and clinicians to develop healthcare systems for the organization to support the service to all public hospitals and clinics in the region.
The eHealth Consortium has been formed to bring together clinicians from both the private and public sectors, medical informatics professionals and the IT industry to further promote IT in healthcare in Hong Kong. MyHDW aims to meet the diverse needs of timely health information provision and management, and acts as a platform for the standardization and integration of health data from a variety of sources Health Informatics Centre, A hospital information system HIS is a comprehensive, integrated information system designed to manage the administrative, financial and clinical aspects of a hospital.
As an area of medical informatics, the aim of hospital information system is to achieve the best possible support of patient care and administration by electronic data processing. HIS plays a vital role in planning, initiating, organizing and controlling the operations of the subsystems of the hospital and thus provides a synergistic organization in the process. Health informatics is taught at five New Zealand universities. The most mature and established programme has been offered for over a decade at Otago. The Saudi Association for Health Information SAHI was established in  to work under direct supervision of King Saud bin Abdulaziz University for Health Sciences to practice public activities, develop theoretical and applicable knowledge, and provide scientific and applicable studies.
The Russian healthcare system is based on the principles of the Soviet healthcare system, which was oriented on mass prophylaxis, prevention of infection and epidemic diseases, vaccination and immunization of the population on a socially protected basis. The current government healthcare system consists of several directions:. One of the main issues of the post-Soviet medical health care system was the absence of the united system providing optimization of work for medical institutes with one, single database and structured appointment schedule and hence hours-long lines. Efficiency of medical workers might have been also doubtful because of the paperwork administrating or lost book records.
Along with the development of the information systems IT and healthcare departments in Moscow agreed on design of a system that would improve public services of health care institutes. Tackling the issues appearing in the existing system, the Moscow Government ordered that the design of a system would provide simplified electronic booking to public clinics and automate the work of medical workers on the first level.
The system designed for that purposes was called EMIAS United Medical Information and Analysis System and presents an electronic health record EHR with the majority of other services set in the system that manages the flow of patients, contains outpatient card integrated in the system, and provides an opportunity to manage consolidated managerial accounting and personalized list of medical help.
Besides that, the system contains information about availability of the medical institutions and various doctors. The implementation of the system started in with the organization of one computerized database for all patients in the city, including a front-end for the users. EMIAS was implemented in Moscow and the region and it is planned that the project should extend to most parts of the country. Health informatics law deals with evolving and sometimes complex legal principles as they apply to information technology in health-related fields.
It addresses the privacy, ethical and operational issues that invariably arise when electronic tools, information and media are used in health care delivery. Health Informatics Law also applies to all matters that involve information technology, health care and the interaction of information. It deals with the circumstances under which data and records are shared with other fields or areas that support and enhance patient care.
As many healthcare systems are making an effort to have patient records more readily available to them via the internet, it is important that providers implement security standards in order to ensure that the patients' information is safe. They have to be able to assure confidentiality, integrity, and security of the people, process, and technology.
Since there is also the possibility of payments being made through this system, it is vital that this aspect of their private information will also be protected through cryptography. The use of technology in health care settings has become popular and this trend is expected to continue. Various healthcare facilities had instigated different kinds of health information technology systems in the provision of patient care, such as electronic health records EHRs , computerized charting, etc.
One of the federal laws enacted to safeguard patient's health information medical record, billing information, treatment plan, etc. Computers and Biomedical Research , published in , was one of the first dedicated journals to health informatics. As of September 7, , there are roughly informatics journals listed in the National Library of Medicine NLM catalog of journals.

Finding the good-fitting curve with a theoretical rationale is the aim of mainstream social science, in contrast to the Pearsonian variant mentioned above. Extrapolation to other cases or beyond a range of observation remains extrapolation, whether it is based on a simple linear model, a double exponential, or a modified Gompertz.
Only theory can hope to tell us whether the extrapolation is justified.
Successes to date with modeling first marriage may be partly fortuitous, and the radical changes in patterns of union formation over the last decades will require new and different models. Later home-leaving, cohabitation, and the delay and avoidance of legal marriage may lead to unprecedented low levels of proportions ever-married, and may lead to a curve of first marriage risk with opposite skewness, or even conceivably bi-modal curves with respect to age.
Suitable curves will differ depending on the inclusion or exclusion of informal unions. Headship rates by age, non-family households Canadian cohorts, — to — But the general point is clear: mathematical models that fit well in the past may not fit well in the future. And our ability to anticipate this is based very much on a theory-based understanding of why the model fits. Well-formulated theory may be the most practical thing of all. The paper reprinted in this chapter is the earliest in the collection.
Demographers are now better acquainted with the Hernes model, which is more often cited, used in research, and featured in textbooks on demographic methods. New cohort forecasts of first marriage for US women. Unlike earlier papers, Goldstein and Kenney move beyond the issue of goodness of fit, and discuss their statistical results in light of microeconomic theories of marriage and of assortative mating.
In his recent text, Essential Demographic Methods , Wachter mentions the Coale-McNeil model but does not discuss it in any detail. He devotes two pages to the Hernes model, noting some limitations and suggesting different approaches to estimation of the proportion eventually marrying relying on maximum likelihood rather than least squares; p. Preston et al.
So, reference to Hernes is far from routine by demographers with an interest in modeling the marriage process. Coale and Trussell revisited the topic in their authoritative review article on demographic models In the section on nuptiality, they devote almost as much space to the Hernes model as to Coale-McNeill, noting that it provides very close fits to observed marriages schedules by race and sex in the United States p.
No deep theory, or even shallow theory, underlies the search for empirical regularities. Read together the above quotes suggest ambivalence about the role of theory in demographic research. One might try to develop theory eventually, but the main tasks for the demographer are empirical research, modeling, measurement and estimation. There is but a qualified interest in theory. Part of the problem, perhaps, is that many of us have had an outdated and inappropriate view of what theory is and how it works.
And by the doctrine of falsification, we search for one best theory, the scientific equivalent of monotheism. My own writing in this sometimes reflects these older views of theory. The comparison of the two models comes close to suggesting that we adopt Hernes rather than Coale-McNeil. Their behavioral content is different, giving different perspectives on the first-marriage process. For some purposes, the Coale-McNeill model may be better than Hernes in the attempt to gain insight into certain aspects of marriage behavior and its causes. Key elements of the model were developed by Griffith Feeney in the summer of see Feeney and shared at a meeting that same summer.
The resulting expression is unwieldy mainly by comparison with the original differential equation, and is no more so than the Coale-McNeil equation. Anecdotal evidence. I became aware of the Hernes model by accident, reading the article that immediately preceded it in the journal. There also has been a general lack of interest in the behavioral rationale for the Coale-McNeil model. Possible complementarities in the behavioral underpinnings of the two models and consequent possibilities of synthesis seem never to have been noted. In the sense that the integral of the risk function cannot be expressed in terms of elementary functions.
In my experience, estimating parameters for Hernes is easier than for Coale-McNeil using the nonlinear least-squares utility in Mathcad. I do not know if this is a problem with other techniques or software. There is a potential link with a large economics literature on search processes and assortative mating, but to my knowledge this link has not been developed in the demographic literature on first marriage. But see Goldstein and Kenney As assessed by this writer, of course.
It is quite possible that I have overlooked some flaws or practical disadvantage in the Hernes model, or failed to see some additional virtues or advantages in Coale-McNeil. It is worth emphasizing the fact, however, that his article was published in what is generally considered the leading sociological journal in North America, if not the world. There is no question of inaccessibility in an obscure journal.
While this view still seems valid, it may need to be qualified to take account of measurement error in complex multivariate models now commonplace in social science, as well as other forms of propagation of error generally. It may be possible to find a functional form that would represent the varied patterns of both older and younger cohorts, but it would be considerably more complicated than functions like Coale-McNeil or Hernes, to capture the non-monotonic character of the curves for younger cohorts.

The next step was to find a functional form that could represent this common pattern. Experiments with various forms initially a double exponential function led to Eq.
Along the way, Coale began to look for a behavioral interpretation: I expressed dissatisfaction with the double exponential risk function on the grounds that it did not provide any evident basis for an intuitive understanding of first marriages. Coale tentatively identifies the stages in a Western context as dating, meeting the future spouse, engagement and finally first marriage. He acknowledges a similar conceptualization of the marriage process in several papers by Henry, but apparently was not aware of these in the early stages of his work.
Goodness of Fit Although I know of no systematic, rigorous comparison of the goodness of fit of the two models across a wide array of empirical data, published evidence and my own experience point to the conclusion that both models fit first marriage curves very well.

Hernes also takes the more correct view of the situation, avoiding the logical fallacy of affirming the antecedent: The general problem with our type of analysis is that the fit between the observed and calculated curve of first marriage is not a strong test of the model But some part of the explanation must lie with the intellectual character of the discipline of demography. A similar structural shift can be seen in cohort data on female rates. In either case, a function that fit older cohort experience quite well would do poorly when applied to younger cohorts, and this will eventually be reflected in cross-sectional data.
