Rowell-Giustini – LIBR534 Does expert searching save lives? Johns Hopkins’ clinical trial volunteer Ellen Roche died in 2001 after she participated in a clinical trial for a proposed asthma treatment... Were health librarians consulted for this clinical trial [link] ?

Rowell-Giustini – LIBR534 Document search - ‘reproducibility’ The following search was run on MEDLINE (Ovid) combined with terms from Phase 1 and 2 of the Cochrane highly sensitive search strategy for identifying RCTs ( Lefebvre 2008 ). Modified terms were used to search the other databases (e.g. Embase): eg. Medline (Ovid) Search String 1 exp Otitis Media/ 2 exp Otitis Media with Effusion/ 3 exp Otitis Media, Suppurative/ 4 glue ear.mp . 5 otitis media.mp. 6 OME.mp. 7 AOM.mp. 8 1 or 2 or 3 or 4 or 5 or 6 or 7 9 exp Anti-Bacterial Agents/ 10 exp Drug Therapy/ 11 exp Anti-Infective Agents/ 12 antibiotic$.mp. 13 9 or 10 or 11 or 12 14 8 and 13 [Intervention Review] Antibiotics for acute otitis media in children Lefebvre C et al.

Rowell-Giustini – LIBR534 Final tip: Reflect on your search skills
Some questions you might want to consider or reflect on :
What did you learn after you completed X search?
What would you change or do differently?
What surprised you about the search process?
What did you learn?
Did you learn on your own – or with others?
What worked for you? What didn’t?
What do you need to do to become an expert ?
“ Reflective practice involves careful consideration of one’s experience in learning…” Donald Schön The Reflective Practitioner 1983.
