well as in the literature databases
3. Be aware of good sites for finding statistics and the
national, state and local levels
4. Become reacquainted with searching with keyword and
controlled vocabulary/subject headings.
Goals and Objectives

3. Key Points to Consider
When searching for statistics ask yourself:
o Are statistics likely to be available on this topic?
o Which organization(s) might collect relevant statistics?
o Where might relevant statistics be published or mentioned?
• websites, reports, yearbooks, bulletins, newspapers, magazines, journals
o What keywords might be used to describe these statistics?
• statistics on the heart can be listed under cardiovascular disease
Be prepared for the possibility that:
o Statistics may not exist for the level of detail or all the
variables wanted
• State of Virginia but not Richmond, VA
o The most recent statistics may be several years old
• census data
o Some statistics are not published/freely available

4.  Many organizations and agencies include health statistics that they
collect or have access to
 Search the Internet for organizations using at least two search
engines [Google/Bing/Yahoo]
 Search for a known organization using quotes, as "American Heart
Association"
 Consider searching by topic, remembering search results are
usually ranked by popularity /are often not ranked by relevance.
 Use synonyms for statistics connected by OR in the search phrase
(as...statistics OR rate OR incidence OR data)
 Use synonyms for the disease or condition in search phrases (as
lung OR pulmonary, heart OR cardiac)
When Searching the Web
for Statistics

5. • Find the CINAHL Heading That is Closest
to the Topic You Are Searching For
• Select one subheading that is related to
statistics (as epidemiology, trends)
(Selecting two or more subheadings will
greatly limit the results)
OR
• Do a second search (using the Suggest
Subject Terms option) with one or more of
these CINAHL subject headings:
Descriptive Statistics, Incidence, or
Data Analysis, Statistical
OR
• Do a second search using one or more of
these keywords: statistics, incidence, or
data
• MeSH subheading : statistics and
numerical data
 can be searched separately as
"statistics and numerical
data"[subheading]
• MeSH subheading: epidemiology
• MeSH heading: incidence
• Potentially Useful Keywords:
statistics, epidemiology, incidence
Searching the Literature
for Statistics

6. Consider the following when evaluating the
usefulness of found statistics or data
• Who collected and published the statistics?
• What are their credentials?
• What data or statistics is being reported?
• What populations are included?
• Is the information current enough?
(Often a time lag between data collection & data reporting because analysis takes time)
• Why was the information collected?
• Who are the intended users?
• What it collected as part of the organization's mission? for
advocacy? for business purposes (as to sell a product?)
• How were the statistics collected? Were any samplings or
surveys done scientifically?

health statistics agency that compiles statistical information.

Care Tech. (NICHSR)/ Data, Tools & Statistics: contains selective

• NIH Institutes and Offices : starting point for disease specific statistical
information.
• FedStats: Makes statistics available from 100+ agencies/programs available.

11. Subject Headings / Keywords

12. Keywords vs. Subject
Headings
Advantage Disadvantage
Controlled
Vocabulary
(Subject
Heading)
A list of subject terms may help you find
an appropriate search term for your
topic.
It can provide you with suggested terms
for narrower, broader or suggested
topics.
Using appropriate subject headings for a
topic, will retrieve all items in the
database indexed under the topic.
Recently coined terms, including new topics
and jargon may not yet be included in the
list of subject terms.
When a database does not provide a thesaurus
or list of subject terms, the controlled
vocabulary might not be obvious.
Keyword
Will retrieve items containing new
terms, distinctive words, jargon.
If you do not know the appropriate
subject heading, descriptor or
identifier for your topic, you can
conduct a key word search first and
look at a relevant item for the
appropriate subject term.
You may retrieve items that are not relevant to
your topic (false hits).
In order to retrieve more relevant items, you
need to use a variety of terms. For example,
to retrieve items about movies, a keyword
search must include terms like films, cinema,
and motion pictures.
