Contents Foreword vii 1 What is health information? However, massive changes are brought about in society by the introduction of technologies that have unforeseen social impacts. For example, the stirrup led to the creation of feudalism; the heavy plough to the manorial system in northern Europe. We spend a great deal of time agonising about the future of the medical profession and the nature of clinical practice and education, but information technology is a tool that will be as dramatic in its impact as the stirrup or the heavy plough.
Often people try to dissociate themselves from information technology and say they are in knowledge management or the information business, but information technology is itself of vital importance and health informatics books free download pdf should be proud to be health informatics books free download pdf the tools. This collection of essays, health informatics books free download pdf, from two distinguished and practical clinical academics, gives an excellent introduction to the revolutionary potential of healthcare information technology, the social impact of which will be enormous.
We are fortunate today that those who create and develop such tools are, unlike their glorious predecessors, able to write—and to write beautifully, health informatics books free download pdf.
I have great pleasure in recommending this book to readers from all backgrounds as an accessible, comprehensive survey of this revolutionary technology. Medieval technology and social change. Information is an ethereal commodity. One definition describes it as the health informatics books free download pdf and knowledge that intelligent systems human and artificial use to support their decisions.
Health informatics helps doctors with their decisions and actions, and improves patient outcomes by making better use of information—making more efficient the way patient data and medical knowledge is captured, processed, communicated, and applied.
These challenges have become more important since the internet made access to medical information easier for patients. Questions on clinical information that often arise in clinical and reflective practice are dealt with, but discussion of specific computer systems is avoided. Some questions on clinical information Medical record keeping x What records to keep? How to communicate with my colleagues and patients x Face to face?

Ms Smith is In her shop, Ms Smith sells a kind of flower that grows on shrubs with prickly stems and serrated leaves. However, each appointment the next week.
Back in the clinical world, the lesson is that we should capture and represent each item of information in a form that helps each user—whether human or computer—to find and interpret it.
These display formats can all be achieved with a paper record, but it would take more time and effort to annotate abnormal Possible formats to display information include informal or structured text, tables, graphs, sketches, and images, health informatics books free download pdf.
The best format for each item of laboratory results with a highlighter pen, graph the values on a information depends on who will use it, how they will use it, for what task, paper chart, or write an alert on a Post-it note and place this on and on the formats readily available.
When information is captured and represented on paper or film, it is hard to change the health informatics books free download pdf in Clinical environment Directory of staff, which each item appears or to display it in other formats. When services Dr Jones Ms Smith When data is coded and structured, or broken down into simple consultant Takes patient elements, it can be processed automatically—for example, the action Communicates computer can add the icon, graph the data, or generate the alert with Captures Accesses data from about Ms Smith.

Patient data are the source in both cases see box opposite.

People with health concerns no longer have to become patients by consulting a health professional. Electronic health eHealth Ms Amulya Patel is a 48 year old accountant whose mother has recently died of breast cancer, health informatics books free download pdf. Ms Patel tools provide access to many resources that may satisfy their wonders about her own level of risk, and uses the internet requirements.
This article describes ways that patients can to search for patient resources investigate health issues before, or instead of, a consultation. As a professional, Ms Patel see box opposite can access health resources on the internet at work and at home. She may subscribe to a mobile internet service provider through her telephone or palmtop computer. Internet access is not restricted to affluent people in western societies. Internet cafes can be found worldwide, and library services often provide time online for free.
Using a search engine Internet search engines are software tools that index and catalogue websites. People with little or no prior knowledge of a subject, but with some experience of searching the internet, often use search engines to begin an inquiry. Advanced searches allow specific phrases, languages, and times to be defined. This reduces the hits to a more manageable number. The most popular sites do not necessarily have features that are the markers of quality preferred by health professionals.
Alternatively, patients can health informatics books free download pdf to the search list and start again. An example of a Google hit—sites chosen by patients usually have immediate facts, such as women have a one in eight lifetime risk of developing cancer Patient orientated health portals These are specalised search engines with additional features such as access to frequently asked questions about health or email facilities.
Individual clinicians, clinics, practices, hospitals, and health maintenance organisations provide portals to their own and other resources. National and local health services for example, the NHS in the UK often provide access to such resources for patients. These portals may link to specific services provided by that health service, such as lists of local cancer genetics clinics. Other portals are provided by independent bodies.
Many have international links and are funded by charities. They vary in quality. Some are quality assured, and when they are not, tools are available to allow patients to assess the portal.
Patients make sophisticated use of multiple sources of information. They sought support and information from patients who had similar issues, obtained information about tests and interventions, and identified questions to ask doctors if necessary.
Many portals link to other websites, and they may direct the person to other resources such as books, multimedia resources, or patient support groups A relevant health service resource accessed through a portal DIPEX allows patients like Ms Patel to read, listen, or watch patients facing similar problems to their own Two examples of quality assured portals Direct access to medical literature Some health portals link directly to websites that present medical literature intended for professional use.
Ms Patel could access impenetrable to non-professionals, and some primary data sources, such as the BMJ or the Journal of Medical professionals Genetics, directly.
Sometimes journals provide free access to all their content, others make only article abstracts or brief summaries available. Most patients will have difficulty in interpreting medical journals as is the case for many doctors. Risk may be described in absolute or relative terms as percentages, rates, multiples, and over different time periods.
