"80% of Internet users look online for health information, making it the third most popular online pursuit among all those tracked by the Pew Internet Project, following email and using a search engine."
Patients should be able to find the information they need in a credible resource!
Medical professionals should be able to find the information need and help patients get similar results.

Timeline of Web Search Engines
93%
of consumers use search engines to find websites.

46%
of those searches are for product or service information.

75%
of search engine users never scroll past the first page.
How do search engines work?
(schematically)
They search the Internet based on important words.

They keep an index of the words they find, and where they find them.

They allow users to look for words or combinations of words found in that index.
New expressions
Search engine
: designed to search for information online
Relevancy
: quality of a search engine depends on how relevant results it can find
Search engine optimization
: the process of improving the visibility of a website in search engines
Let's search on the web!

Let's see how patients search online
What do they search for?
Patients can search on
search engines
Twitter
Social networks such as Facebook
Community sites
Newsletters
Blogs
Video channels
Slideshows
And many more...
Medical professionals should at least know about these platforms.
A few examples where they do search
More details about this in the "World of E-Patients" prezi
How medical
professionals
search online
A popular tool: Pubmed.com
a free database accessing the MEDLINE database of references and abstracts on life sciences and biomedical topics
Maintained by the United States National Library of Medicine at the National Institutes of Health
Launch: January, 1996
There are a few ways to search and follow the biomedical literature
Save search and set up automatic e-mail alerts
Create custom RSS feeds for journals, authors or other search queries
When a journal does not have RSS feed,
you can create one with this method
An alternative method (in genomics):
Assigning faces to papers while mimics correlate with the importance of the paper
Personalized solutions
Sciencerollsearch.com
Searching only in the databases a medical professional needs (e.g. drug; WHO; clinical trials, etc.)
Clustering search engine helps you find what you need with relevant categories
You don't have to search again and again for
your name
your field of interest
whether your paper is cited
solution
Alerts.google.com
I want to follow

How to search in this database?
Red Cross stamp

Red Sea stamp

Stamps with red graphs

And red stamps
How could it understand?
Stamp is a stamp

Red is a color
Wolfram Alpha
What about the semantic web?
"The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries."
The term was coined by
Sir Tim Berners-Lee
,
the inventor of the World Wide Web
Let's see a practical example
I start collecting stamps
I create a document about each stamp
Then I'll have a lot of documents
I'm looking for red stamps
I do a search for "red stamps"
and it's going to find:
It should understand that
It has to understand the difference between features such
as color or name
which means
we have to teach the database to understand these features
One of the first and successful examples
Asking questions and getting answers instead of search results
Calculating and visualizing body mass index
"BMI 180cm 78kg"
Risk estimations
Epidemilogy data
Lab test results
Drug information
Asking questions
Take home messages
Learn how your patients and colleagues search online
Search wisely, there are many tricks and tips
Save time and efforts!
Choose the right engine for your purpose (image or document; papers or websites?)
The more searches you do, the better you become at it!

There is one exception:

It does not alter your search results
