This section presents a number of exercises and directions for their completion. Please answer all questions (in an orderly fashion) related to the exercises and paste snips/screenshots in your Assignment Document. Please feel free to write the librarian if you have questions. There are a few exercises on tab 2 as well, which should be included in your Assignment Document.
If you are not asked a question or given a direction, then you don't need to include something. If you are in doubt, there is never a problem with putting something in the document.
Please view each of the tutorials below and enter answers or SNIP/screenshots as requested into your Assignment Document. The tutorials are drawn from YouTube, including an excellent series by Roy E Brown of the VCU Libraries and the National Library of Medicine's tutorials.
1. Searching by Breaking Question into Concepts (Roy E Brown, VCU Libraries- approx 4.5 minutes) https://www.youtube.com/watch?v=7dSCYHSgyv4
Why does Brown suggest separate concepts searches which are joined later? (Assignment document)
2. Coming Up with Alternative Terms (Roy E Brown, VCU Libraries-approx 4.5 minutes) https://www.youtube.com/watch?v=NaXK6rA01TE
Can you name 4 places you might search to find alternative terms for a search? (Assignment Document)
What does R Brown say is a key factor in the kinds of terms a specific searcher first considers? (Assignment Document)
3. Search with Controlled Vocabulary (Roy E Brown, VCU Libraries- approx. 9 minutes) https://www.youtube.com/watch?v=Q4w6T6aovIQ
Name 4 benefits of using controlled vocabulary that R Brown mentions. (Assignment Document)
What does R Brown tell us about the retrieval of citations when we use terms from the top of a hierarchical subject tree? (Assignment Document)
Where is controlled vocabulary found in the citation record in PubMed? (Assignment Document)
Go to PubMed. Enter this number in the search box and search: 26591098. Next, go to the pulldown menu labeled Abstract (upper left part of the page). Select MEDLINE from the pulldown – when the MEDLINE display appears, cut and paste the MH field tags (left margin/column) into your Assignment Document – the first one is
MH - Cross Infection/*prevention & control
When you perform a MeSH only search this is only part of the citation record that is looked at to retrieve a citation. Copy and paste the title field TI into your Assignment Document. When you search for title only, then only this field is searched. If no search field is indicated, then the default is to have all the fields searched in the citation record. A good practice can be to search with a MeSH field indicated or several if appropriate – together with keywords which have may or may not have an attached search field indicated. Sometimes searches will use the MeSH fields and the title fields if the searcher feels confident that a subject will appear in a title in the event that it was never indexed with the MeSH (there are a number of citations which are in PubMed but never indexed although this is not the rule).
4. Starting Search Broad and Then Narrow (Roy E Brown, VCU Libraries- 4.4 minutes) https://www.youtube.com/watch?v=y2WJ-HKfqLo
Name 3 ways you can narrow your search in a database like PubMed? (Assignment Document)
5. Boolean Operators (Roy E Brown, VCU Libraries- approx. 4.3 minutes) https://www.youtube.com/watch?v=qLw8dAoLxqI
Which Boolean Operator (AND vs OR) does not require a relationship between concepts in a search? (Assignment Document)
In the tutorial, R Brown presents a grid showing the concepts linked by OR which are intersected by AND (ORing of concepts occurs row by row, while ANDing of concepts occurs across columns). The headings of the columns are “Hand Washing” (column 1) and “Hospital Acquired Infection” (column 2).Please recreate this grid in your Assignment Document (don’t do a screen print – go through the process of recreating his grid by hand so you have time to think through the process and patterning). Include the bracketed content too as it indicates subject headings and keywords. Learning how to create this kind of a grid for all your research topics is a most important behavior to become an organized, accurate, and comprehensive searcher.
Note, R Brown’s grid is theoretical to cover diverse databases. The current PubMed subject headings are actually different in a few instances. The grids you actually use in constructing searches across multiple databases should be precise with respect to the specific database being searched. The point of this exercise is to start learning this organizational pattern and use of Boolean Operators so that you can apply it to diverse databases, which will always vary by subject headings.
6. Keyword Searching (Roy E Brown, VCU Libraries– approx. 10 min) https://www.youtube.com/watch?v=iK8LZRgc0s4
Name 5 circumstances (according to R Brown’s tutorial) where your search is enabled by searching with keywords. (Assignment Document)
Name 5 circumstances (according to R Brown’s tutorial) where is it helpful to do more than a keyword search. (Assignment Document)
What is the benefit of searching for a phrase or grouping with quotation marks? (Assignment Document)
7. Searching PubMed with Keywords (Roy E Brown, VCU Libraries- 7 minutes). NOTE: Where R Brown talks about Get it @VCU, you can substitute Find it @ UIC. https://www.youtube.com/watch?v=eEY1r_GDzcg
Search for Patient Safety and show the details box for this search (Assignment Document)
Search for (Patient Safety) and show the details box for this search (Assignment Document)
Search for "Patient Safety" and show the details box for this search (Assignment Document)
Show Patient Safety AND A-TOPIC-OF-YOUR-CHOOSING (Assignment Document)
The point of this exercise is to experience the ways in which PubMed translates a query - don't rely on a "rule" but always look at the query box to see what it actually did with your search. Note, PubMed looked for "Patient Safety" (in quotes to indicate a phrase) in its internal translation table of known phrases and it did not break the quoted phrase apart. If it did not find a quoted phrase in the table, it would return with a message close to the top telling you the phrase is not found and it would break the phrase in quotes apart to search each individual word and the phrase as a whole. Always look at the translation.
8. Doing a Medical Subject Heading (MeSH) Search in PubMed (Roy E Brown, VCU Libraries- 6 minutes). https://www.youtube.com/watch?v=1HMvR6kLBDY
Show a SNIP/Screenshot of the MeSH term record for Obesity. Only the word Obesity appears on this page. Now, use the PubMed Search Builder box by pressing the Add to Search Builder button, which automatically pops the term Obesity in the box. Show the PubMed Search Builder box with the term added to it. Then, perform the PubMed search and show the results page. (Assignment Document)
Show a SNIP/screenshot of the entry terms for Carbonated Beverages from the MeSH database (Assignment Document)
Show a SNIP/Screenshot of the MeSH page and entry terms for Patient Safety. Note in your Assignment Document, the date the term entered the MeSH database. Now, search for Patient Safety in the MeSH databases and use the PubMed Search Builder box on the MeSH page and the Add to Search Builder button to perform a PubMed search of the MeSH term. If you do a MeSH search for Patient Safety, how many citations do you find? Now, put this phrase in quotes in the search box for PubMed (not the MeSH page) - "Patient Safety". How many citations do you find? Finally, if you search for the phrase - “Patient Safety”[mesh] OR “Patient Safety” – how many citations do you retrieve? Note, since Patient Safety is a MeSH term, entering the keyword phrase - "Patient Safety" - will cause the keywords to be searched as a phrase as well as the MeSH term (see the automatic query translation in the details box). (Assignment Document)
9. PubMed: Searching with the MeSH Database (NLM, approx. 2.3 minutes) https://www.youtube.com/watch?v=nF_oQNtnbuQ
What is a major heading in PubMed? (Assignment Document)
10. PubMed: Applying Subheadings and Other Features Using the MeSH Database (NLM, approx 4 minutes) https://www.youtube.com/watch?v=LTtrvUQLsWo
11. PubMed: Search by Author (NLM, approx 2 min) https://www.youtube.com/watch?v=kKAp5jc8g5s
In addition to the method of author searching shown above, there is another helpful tool provided by PubMed in the Single Citation Matcher search.
Here is a video from the University of Maryland medical library on this citation finding tool: https://www.youtube.com/watch?v=ydJWxRwjxjE
KEEP GOING ON ASSIGNMENTS ALL THE WAY TO THE BOTTOM OF THE WEB PAGE- THERE ARE 20 EXERCISES!
12. The 5 Tips for Searching PubMed tutorial by Duke University Medical Center Library demonstrates a patient safety topic search in PubMed - https://www.youtube.com/watch?v=6wWeeCBBlk4
This tutorial explores the patient safety search using 3 key concepts –
1) Health care workers 2) Influenza vaccine 3) Patient infection
Sign in to your MYNCBI account. Return to the PubMed homepage. Please duplicate the Duke search in PubMed by following all of the steps in the tutorial exactly as shown - this is a challenge. Show your work via snip/screenshots in your Assignment Document.
Begin by finding the PubMed home screen through the LHS Library website http://researchguides.uic.edu/c.php?g=252191 - scroll down under Research Databases until you find PubMed. Consider bookmarking the LHS Medicine homepage.
After completing the 3 separate searches for Health care workers, Influenza vaccine, and Infection (you will need to copy the Duke modification of the Health care worker term from the tutorial), go to the Advanced page using the Advanced link under the PubMed search box. Create a search that intersects all 3 concepts (use AND to join the concepts together in an intersecting relationship). Show a snip/screenshot of your work from the Advanced page with the combined 3-concept search.
Currently, the search recreation should bring you about 202 search results. Write the librarian if you are struggling with this. Also, an easy way to get it right is to make a snip of the screen that shows you Duke's Advanced search page - then you can see exactly how they did it.
13, View this tutorial for directions on using Filters and the Advanced page to complete the additional exercises: PubMed Advanced Search by the University of Michigan Library https://www.youtube.com/watch?v=vtjrN752Occ
On the search results page for the combined search above, use the following filters to modify the search – English language, last 10 years, randomized controlled trials. You will have to use the “Customize” and “Show additional filters” links to see some of these filters before you can select and apply them. Remember that the filter is not applied until you see the blue checkmark. The search results are finally reduced to about 3 citations once all the filters have been added. Show your work with a snip/screenshot.
Please follow the steps exactly in this exercise. You will be able to judge the correctness of your follow up by the results answers given at each step. Your aim is to duplicate these results exactly.
Remember that when you use the left-column filters in PubMed, sometimes a two-step process is required. For example, when choosing an Article Types filter, first you request to see the filters by pressing More under the Article Types section heading, then you select whatever article type you do want to see. Once the article type appears on the filter list, you have the option to select it. A check mark should then appear to indicate that this filter is set.
a. Enter PubMed via the LHS gateway and sign into your MYNCBI account.
b. In the search box, enter the following search string into the PubMed search box: ("2010/01/01"[Date - Completion] : "2014/05/19"[Date - Completion]) AND (patient safety and communication) Your results should be about 2,417 results.
c. Go to the Ages filter section. and select More. When the filters menu appears, select 80 and over: 80+ years
Your results should now be 89
d. Return to the Article Types filters and press More. Select the Comparative Study box and Show. When the Comparative Study option appears, select it.
Your results should now be 9
e. At the bottom of the column, select the Show Additional Filters link. Select Journal Categories and press Show. Select the Nursing Journals filter in the Journal Categories section.
Your results should now be 2. The PMIDs of the remaining articles are 22271215 and 19773144
f. Go to the Clear All link and select it.
Your results should now be 2,417 as before!
g. Under the PubMed search box, select the Advanced link. This link will show you the recent search history. Note, this history from the Advanced page is temporary. It follows the IP address of the physical computer and browser - it lasts 8 hours only.
Find the search with 89 results and select the number link itself. You should land back on the results page. Note, the age filter 80+ is applied to this set. Now, select Core Clinical Journals from the appropriate filter section.
Your results should now be 6.
h. Select Evaluation Studies from the Article Types Filters. (Remember select the More link and select the Evaluation Studies box, then press Show. Next, select this link and verify it by the check next to the study type).
Your results should now be 1.
i. Remember to Clear All your filters again!
Once you have completed steps a-i above - Using the Advanced page link (beneath the search box), go to recent search history and show a snip/screenshot of the searches above into your Assignment Document. If you have extra searches in the box, you can delete them by selecting the Search # (see the search column on the Advanced page) and choosing the Delete from History link. This is useful for cleaning up your record.
`Complex String Construction Assignment: You must read all of these instructions please!
Your task is to construct several complex search strings that include 3 terms that are subordinate to the MeSH term “Health Services” in the MeSH tree – together with terms related to the concepts of “Patient Safety” and “Quality Improvement”.
I will model the first string for you and ask that your recreate it by typing the string manually into your Assignment Document – please do NOT use the screenshot/SNIP tools because I want you to think about what you are doing.
Look up “Health Services”[MeSH] in the MeSH database. You will see over 150 subordinate child and grandchild terms, beginning with “Adolescent Health Services”, “Child Care”, “Infant Care”, etc.
Pick your 3 child terms and create the MeSH string for each term using the MeSH builder. For each term, look at the MeSH record and put the Entry Date for the term in your Assignment Document. For each of the 3 terms, also construct a keyword phrase the way I did. In the case that you pick a term where the MeSH does not translate to a natural English phrase, write it as a natural language phrase.
We will also use both the terms “Patient Safety” and “Quality Improvement” as MeSH terms and keyword phrases in a unified concept set. Note, I use keyword phrases for terms like Patient Safety, which had a very recent entry date of 2012. A MeSH-only search for Patient Safety would exclude decades of research prior to 2012.
My Example – (Watch the use of parentheses!):
First, I construct the CONCEPT SET for the children of “Health Services” – notice I keep the keywords phrase in quotes. So, this to be part of this unified first set, an article only has to contain one of these 6 terms.
("Adolescent Health Services"[Mesh] OR “adolescent health services” OR "Community Health Services"[Mesh] OR “community health services” OR "Emergency Medical Services"[Mesh] OR “emergency medical services”)
Secondly, I construct the CONCEPT SET for patient safety and medical errors (you can just copy this). So, to be part of this unified second set, an article only has to contain one of these 4 terms. I am using OR in this example to treat these concepts as relatives comprising a larger family, but I could also treat them as intersecting concepts if I put AND between them. They are not identical concepts but often show up in the same fields and research areas.
("Patient Safety"[Mesh] OR “patient safety” OR "Quality Improvement"[Mesh] OR “quality improvement”)
Third, I combine the first and second concept sets together using AND to create an intersection of these first 2 concept sets. So, to be part of this combined set, an article must satisfy the inclusion condition of the first set plus the inclusion condition of the second set. An article about "patient safety" and "emergency medical services" will satisfy both conditions and be in the result set.
(("Adolescent Health Services"[Mesh] OR “adolescent health services” OR "Community Health Services"[Mesh] OR “community health services” OR "Emergency Medical Services"[Mesh] OR “emergency medical services”)) AND (("Patient Safety"[Mesh] OR “patient safety” OR "Quality Improvement"[Mesh] OR “quality improvement”))
Now, you do a string for your Assignment Document!
Use at least 3 child terms from the parent “Health Services” in the string. Use the MeSH term and also use a phrase between quotes as a keyword term. Sometimes this is as simple as translating the MeSH term - "Patient Safety"[MeSH] - to "Patient Safety"
Note, the keyword phrase will bring you many more search results than a search that uses only the MeSH term.
Use the "Patient Safety" OR "Quality Improvement" string from above to intersect your 3-concept string. Follow the format I laid out.
Please highlight the Boolean Operators the same way that I did so you are clear about what you are doing the first few times – do not hesitate to write me at firstname.lastname@example.org if you have any trouble.
Go to the AHRQ PSNET website: https://psnet.ahrq.gov/
Select Topics from the upper pull-down menu. Choose "Safty Target" from the list. Choose "Fatigue and Deprivation".On the left sidebar, choose Setting of Care/"Patient Transport". This should produce about 3 articles. Please take a screenshot/snip of this results page with the 3 or so articles and paste it into your Assignment document.
Now, have some fun on your own with exploring this wonderful resource! The best is sometimes last ...and sometimes fast.
IMPORTANT NOTE: If you have a problem logging into the MyNCBI account again or get a frame-within-a-frame problem, try these steps -
1 Logoff MYNCBI in every site and on every browser
