12. Formulating a Question Think about what you are looking for

13. The problem Pick a topic area to demonstrate – briefly describe the problem

14. The answerable question Convert the problem into an answerable question

15. P I C O – The anatomy of a good question P – Patient/Population/Problem P – Patient/Population/Problem Who or what is the question about Who or what is the question about I – Intervention/Exposure I – Intervention/Exposure What is being done to or happening to the above What is being done to or happening to the above C – Comparison (if appropriate) C – Comparison (if appropriate) What else can be done instead of the above What else can be done instead of the above O – Clinical Outcome O – Clinical Outcome How does the intervention affect the patient: How does the intervention affect the patient: (diagnosis/screening, prognosis, therapy, event, harm, prevention)

19. Truncation A helpful little symbol used when a root of a word has multiple endings – even just multiples! A helpful little symbol used when a root of a word has multiple endings – even just multiples! * Prophyl* gives prophylaxis or prophylactic etc. BUT Tonsil* gives tonsils, tonsillitis, tonsillectomy – this is one to be careful with because tonsillitis is a problem and tonsillectomy is an intervention Tonsil* gives tonsils, tonsillitis, tonsillectomy – this is one to be careful with because tonsillitis is a problem and tonsillectomy is an intervention In this case us a number if all are not require e.g. tonsil*5 will preclude tonsillectomy. In this case us a number if all are not require e.g. tonsil*5 will preclude tonsillectomy.

20. Proximity = ADJ3 E.g ADJ3 placed between two words finds phrases with the words in any order within 3 words of one another E.g ADJ3 placed between two words finds phrases with the words in any order within 3 words of one another E.g. Tonsil$ adj6 surg$ will produce tonsil surgery OR surgery of the tonsils OR surgical removal of the tonsils, surgery for tonsillitis E.g. Tonsil$ adj6 surg$ will produce tonsil surgery OR surgery of the tonsils OR surgical removal of the tonsils, surgery for tonsillitis

21. Words and terms Give examples of words and terms that you have found; asking for others from your audience etc. etc. etc…………… etc. etc. etc……………

22. You have to think like this for each area of your question!

23. Using a thesaurus Using a thesaurus A controlled vocabulary used to index information A controlled vocabulary used to index information Every review, article etc. will have been assigned Subject Headings or Descriptors Every review, article etc. will have been assigned Subject Headings or Descriptors Cochrane Library and Medline etc. use MeSH Cochrane Library and Medline etc. use MeSH EMBASE uses Emtree Classification EMBASE uses Emtree Classification

24. Thesaurus v Free text (1) Thesaurus headings are standard and consistent terms used to describe a subject Thesaurus headings are standard and consistent terms used to describe a subject e.g. heart attack is indexed to myocardial infarction: e.g. heart attack is indexed to myocardial infarction: hip replacement = arthroplasty, replacement, hip hip replacement = arthroplasty, replacement, hip Indexers are always instructed to use the most specific term available Indexers are always instructed to use the most specific term available

25. Thesaurus v Free text (2) What if there is no abstract and your term is not in the title? What if there is no abstract and your term is not in the title? You have to rely on the Subject Headings assigned to the article You have to rely on the Subject Headings assigned to the article What if there is no Subject Heading? relatively new terms What if there is no Subject Heading? relatively new terms MeSH is stronger for searches on conditions and interventions MeSH is stronger for searches on conditions and interventions You have to rely on keywords as well as subject headings You have to rely on keywords as well as subject headings Free text is used to broaden your search Free text is used to broaden your search

26. Combining searches Combine concepts with: OR / AND

27. OR Fill in a few keywords/MeSH terms in the boxes below (MeSH) Subject broadened to include all terms (Keywords)

28. AND Fill in P & I in the boxes below or any combination e.g. Tonsillitis and Prophylactic antibiotics etc. in the SAME article etc.

29. Putting it all together Fill in the PICO with some of the terms used to demonstrate out systematic it is. This seems to pull it all together – delete if not required. OR PI C O OR ANDAND ANDAND OR 7608132594 6245 38
