Conducting Lit Searches for Systematic Reviews
Shannon KealeyInstructional Services Librarian
Pace University
Steps
1. State your focused clinical question in PICO format
2. Make a chart with each of the columns starting with P, I, C, O
3. Under each PICO element, list all relevant MeSH and CINAHL subject headings, as well as keyword equivalents that are not subject headings (use EBSCO interfaces to find Subject Headings)
Sample Clinical Question
What continuity of care interventions are most effective in improving patient satisfaction and reducing hospital readmissions in adult patients receiving home care services?
Sample Search Term Chart
P I C O
Home care services (MeSH)
Continuity of patient care (MeSH, CINAHL)
NA Patient readmission (MeSH)
Home care agencies (MeSH)
“Care pathways” (KW) Readmission (CINAHL)
Home health agencies (CINAHL)
“Integrated care” (KW) Patient satisfaction (MeSH, CINAHL)
“visiting nurses” (KW)
Patient care team (MeSH) Readmit* (KW)
Community Health Nursing (MeSH)
Primary health care (MeSH) Rehospitalization (KW)
P: home care servicesI: continuity of care
C: NA
O: patient satisfaction or hospital readmission
Finding MeSH Headings
Always select “Suggest Subject Terms”
Copy the appropriate heading(s) to include on chart—run search later in PubMed when you
also have CINAHL headings
Finding CINAHL Headings
Always select “Suggest Subject Terms”
Copy the appropriate heading(s) to include on chart—run search now ONLY if you have already found all your MeSH
headings (so you can run MeSH as Keywords in CINAHL)
Click to search
the CINAHL heading
Steps (cont’d)
4. Search the databases, combining each MeSH heading, CINAHL heading, and keyword for each element with the OR operator
5. Use AND to combine the final set for P elements with the final set for I elements, etc.
Sample PubMed Search History
MeSH headings—no quotes
CINAHL (not MeSH) & KW phrases--quotes

Sample CINAHL Search

MeSH & KW phrases--quotes
CINAHL heading—no quotes but “OR” w/ KW version of heading (has quotes)
What NOT to do!
Remember!• When you run your searches, always use the
PubMed interface to Medline (includes “In-Process” and “Epub ahead of print”—newest studies)
• If you come across new MeSH or CINAHL headings as you search, add them to your chart and re-run your searches to include the new heading in all databases
• Save your PubMed searches into your MyNCBI account; save your CINAHL and PsycInfo (if applicable) searches into your MyEBSCO account
