technologies as it related to the healthcare delivery

● What is knowledge, data, information, wisdom and information:
❏ Raw facts (numbers/ statistics)
❏ Exist without meaning or interpretation.
❏ The attributes that health care professionals collect, organize, and name.
❏ A collection of data that has been processed to produce meaning.
❏ Techniques used to process data include: classifying, sorting, organizing,
summarizing, graphing, and calculating.
❏ Knowledge is built from information.
❏ A collection of interrelated pieces of information.
❏ The interrelationships are as important as the individual items of information.
❏ Information in a knowledge base is organized or structured so that
interrelationships can be identified.
❏ Learner’s develop a knowledge base then uses the knowledge to interpret new
data or reinterpret old data producing new information.
Wisdom--drawn from knowledge
❏ Knowing when and how to use knowledge to make ethical
decisions that ensures cost-effective quality care.
❏ Knowledge allows caregivers to explain medical stages of an
illness; wisdom allows the caregiver to use theories to relate the
attributes of an illness to allow patients to express how they feel.
❏ Wisdom cannot be automated.
❏ Certain concepts of wisdom are being built into automated systems
known as Expert Systems

multitasking. Dos is based on plain interface while Windows is based on
Graphical user interface (GUI).
● Computer terms:
○ Computer-an electronic device that collects, stores, processes, and retrieves
○ Mainframes-large memory capacity, work at high speed, and have the ability for
many users to operate the computer system at the same time
○ Chip- a small piece of silicon that has electrical circuits. The fundamental
component of a computer
○ ROM (Read Only Memory)- memory that is stored by the manufacture. Cannot
be changed or manipulated; memory that allows the computer to turn on and run
○ RAM (Random Access Memory)- memory not used for computer functioning;
memory space in a computer to store programs and information
○ BIT: the smallest part of the computer memory
○ Megahertz: unit of measure for the speed of computer processing
○ CPU (central processing unit) : hard drive
● How did it begin:
○ Began in 1969-ARPAnet (Advanced Research Projects Agency) Department of
● How is it regulated
○ Not regulated by anyone (for now), however people pay for access
● Domain names
○ .com , .gov, .edu., .org, .mil, .net
● Evaluation of a web site
○ Criteria: Authority/Accuracy: When judging the Authority of a web
resource/website, look at the following:
○ Who is providing the information?
○ What are their qualifications?
● URL Hints (.gov, .org, .net, .edu, .com)
● Links - where does the site lead you?
● Contact information
● Helpful Hint: If you truly are not sure who is sponsoring a particular site,
try a WHOIS search - to determine who owns a website/domain name.
When judging the Accuracy of a web resource/website, look at the
● Is it sloppy or full of errors?
● Are sources given?
● Has the site been evaluated?
● How did you find this site?
○ Broad search engine?
○ Selective directory?
○ Link from a reputable source?
○ Criteria: Purpose/Content: When assessing the Purpose and Content of a web
resource/web site, consider the following:
● Stated or implicit purpose
○ Commercial use
○ Personal page
○ Hacked information
○ What topics are included
○ Are the topics explored in depth
● Evidence of bias
○ Is there a minimum of bias?
○ To what extent is information contained on the site trying to sway
○ Criteria: Currency: Depending upon the purpose of the website (see above),
Currency may need to be taken into account. Considerations include:
● Update frequency - is this historical data (a copy of an old map), or does it
need to be current (e.g. stock information)?
● Currency of links - are links from the page/site current, or are they out-ofdate?
○ Criteria: Design, Organization, and Ease of Use: The last criteria helps you
determine the usability of a page. Considerations for Design, Organization and
Ease of Use include:

productivity, people expect prompt returns, spyware/worms/viruses might affect
hardware may lead to identity theft, prolongs communication
