Accessing health information is one of the commonest reasons for going on-line: surveys show that 50% to 75% of World Wide Web users have used it to look for health information, and those who do so access such information over 3 times a month.
 +
 
 +
In December 2001 the NHS Direct consumer health information Web site (http://www.nhsdirect.nhs.uk/) dealt with 5.2 million hits from 171900 visitors.
 +
 
 +
 
 +
The increasing availability of interactive information that is accessible to consumers, most notably through the internet and related technologies such as digital television and web television, coincides with the desire of most consumers to assume more responsibility for their health and the pressures of costs on health systems, the emphasis on the health of populations and on prevention, and the growing desire of health professionals to realise the potential of patients and their families.
 +
 
 +
 
 +
Information technology and consumerism are synergistic forces that promote an "information age healthcare system" in which consumers can, ideally, use information technology to gain access to information and control their own health care, thereby utilising healthcare resources more efficiently. Today's "cyberdocs" on the internet may tomorrow turn into more trustworthy "cyberlicensed" professionals counselling patients online. This development is under way in the United Kingdom with the introduction of services such as NHS Direct, which provides advice to patients both on the web and over the phone.
 +
 
 +
Additionally, intelligent informatics applications can channel the floods of health information reaching consumers, can help patients attain a healthy balance between self reliance and seeking professional help, and can also help balance responsiveness to consumers and the management of demand, and virtual and face to face interaction.
 +
 
 +
Information technology and consumer health informatics are becoming an integral part of modern concepts of public health and national healthcare policies in many developed countries.

 +
 
 +
The project is developing a technical infrastructure to allow individuals, organisations, associations, societies, and other entities to rate the published health information found online by using a standardised vocabulary.

Description

Accessing health information is one of the commonest reasons for going on-line: surveys show that 50% to 75% of World Wide Web users have used it to look for health information, and those who do so access such information over 3 times a month.

In December 2001 the NHS Direct consumer health information Web site (http://www.nhsdirect.nhs.uk/) dealt with 5.2 million hits from 171900 visitors.


The increasing availability of interactive information that is accessible to consumers, most notably through the internet and related technologies such as digital television and web television, coincides with the desire of most consumers to assume more responsibility for their health and the pressures of costs on health systems, the emphasis on the health of populations and on prevention, and the growing desire of health professionals to realise the potential of patients and their families.


Information technology and consumerism are synergistic forces that promote an "information age healthcare system" in which consumers can, ideally, use information technology to gain access to information and control their own health care, thereby utilising healthcare resources more efficiently. Today's "cyberdocs" on the internet may tomorrow turn into more trustworthy "cyberlicensed" professionals counselling patients online. This development is under way in the United Kingdom with the introduction of services such as NHS Direct, which provides advice to patients both on the web and over the phone.

Additionally, intelligent informatics applications can channel the floods of health information reaching consumers, can help patients attain a healthy balance between self reliance and seeking professional help, and can also help balance responsiveness to consumers and the management of demand, and virtual and face to face interaction.

Information technology and consumer health informatics are becoming an integral part of modern concepts of public health and national healthcare policies in many developed countries.

National healthcare policies


Information technology and consumer health informatics are becoming integral parts of the modern concept of public health and national healthcare policies.


Developping or adapting existing computer based decision support systems for use by consumers


One decision support system that is being adapted and tested for consumers is HouseCall (Applied Medical Informatics), an informatics system derived from the existing physician knowledge base Iliad.

Focus group evaluations of HouseCall have shown that the program is easy to use and that consumers like using technology at home to investigate health issues and like participating in solving their medical problems.

The main challenge in developing comprehensive systems for consumers is that little is known about how patients interact with computer based informatics tools and how they digest and act on information.

Smart cards can be used as places to store health information directly, or the electronic medical record can be put onto the internet and smart cards can serve as keys by providing access. Just as consumers bank online today, they may in future be able to browse and annotate their health records online.

Access to information on the internet


The information society brings a risk of a widening of the gap between those who have access to new technology and those who have been excluded.

In the information age, we face an analogous "inverse information law"- that is, access to appropriate information is particularly difficult for those who need it most.


Confidentiality of Electronic Medical Records


Electronic medical records (EMRs) are rapidly becoming the standard among hospitals and large physician organizations, and should be universal among health providers in all settings by the year 2020. However, consumers are paranoid that their medical records could be accessed by their employers, insurance companies, banks and lenders, credit reporting firms, or vendors of massive consumer databases.

Online prescribing of Viagra, Propecia, Xenical, and other popular lifestyle pharmaceuticals has led to calls for new governmental regulation.

In spite of this, 94% found the information helped them cope better with stress and anxiety during the pre-operative and post-operative period. Almost all felt that easier language should be used in medical information on the Internet.
