What is a Systematic Review?
AAAL Fall MeetingNovember 21, 2013
Liz Dennett and Sandy Campbell
And why should you care?
What are systematic reviews?One outcome of evidence based healthcareHelps to synthesize the evidence to provide
the best patient careEach systematic review follows an explicit,
reproducible and rigorous methodologyNon-biased and comprehensive
Process overviewStarts with a clearly defined question using
the PICO model (Population, Intervention, Comparison, Outcome)
Systematic search to identify all studies. Searches aim for comprehensiveness and are run on all relevant databases as well as grey literature sources.
Search results are screened (first in abstract form and then full text) to ensure they are relevant to the PICO and meet all criteria.
Process overview, cont’dIncluded studies are critically appraised for
their quality and risk of bias (done using standardized tools)
Results are synthesized in descriptive form or (if the studies are considered homogenous enough) the data is pooled in a meta-analysis
Goal is a more definitive answer than any single study can provide
Example Medline search Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R)
Daily and Ovid MEDLINE(R) 1946 to Present Search date: Sept 18, 2013 Results: 198 1. Robotics/ 2. (robot* or "bi manu track" or mitmanus).mp. 3. 1 or 2 4. stroke/ 5. (stroke or post-stroke or tia or cerebrovascular accident* or post-tia).ti. 6. 4 or 5 7. exp Upper Extremity/ 8. (Upper extremit* or hemipares* or hemiplegi* or hand or hands or arm or arms or
upper limb* or finger or fingers or thumb or thumbs).mp. 9. 7 or 8 10. 3 and 6 and 9 11. exp Clinical trial/ or randomized.tw. or placebo.tw. or dt.fs. or randomly.tw. or
trial.tw. or groups.tw. 12. 10 and 11
So what?Systematic search step of these reviews has
transformed health sciences librarianshipCreated new jobs, created stronger liaison
links, librarians seen as a member of the research team, research publications
Started slowly but now many students are doing them as part of their thesis. Created a huge demand for our time
Knocking on your door?Good chance if supporting areas where
similar research is carried out multiple times, such as Librarianship, Education, Psychology, Sociology, Policy, Agriculture, Applied sciences
Probably not – Chemistry, Physics, English, History, Fine Arts
TrainingTalk to a health sciences librarian – Health
library associations offer training at the national and local level
