Transcript

  • 1. Exercise 1 – Suggested solution Question: What is the survival rate of extremely premature infants? 1. Patient/problem Extremely premature infants 2. Intervention or Exposure 3. Comparison 4. Outcome Survival rate What type of question is this? Diagnosis Prognosis Etiology Therapy Experience Which search terms should be used? Use the PICO model to note all relevant search terms. Make sure to include all synonyms. It is not always necessary or smart to search for all the different parts of the question, decide which parts are essential. P I C O Patient/problem Intervention/exposure Comparison Outcome extremely premature survival rate premature infant survival time very low birth weight Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 2. Suggested search strategies: PubMed Clinical Queries: This stragegy will give more results: (extreme* premature OR very low birth weight) AND survival rate With MeSH database: Identify the correct MeSH terms via MeSH database and search for these. In this case it may be smart to search for Infant, Premature OR Infant, Very Low Birth Weight first. Then do a new search for Survival Rate. Go to History to combine the searches with AND. Then find the number of the combined MeSH search. Go to Clinical Queries and put in the number of the MeSH search. Finding Evidence Based Clinical Information in The Cochrane Library and PubMed.

  • 3. Exercise 2 – Suggested soulutions Question: Can the use of mobile phones cause brain cancer? 1. Patient/problem Everybody who use mobile phones 2. Intervention or Exposure Mobile phones 3. Comparison 4. Outcome Brain cancer What type of question is this? Diagnosis Prognosis Etiology Therapy Experience Which search terms should be used? Use the PICO model to note all relevant search terms. Make sure to include all synonyms. It is not always necessary or smart to search for all the different parts of the question, decide which parts are essential. P I C O Patient/problem Intervention/exposure Comparison Outcome mobile phone bran cancer cellular phone brain tumor cell phone brain tumour cellular telephone brain neoplasms mobile telephone intracranial cancer intracranial tumor intracranial tumour intracranial neoplasms Finding Evidence Based Clinical Information in The Cochrane Library and PubMed.

  • 4. Suggested search strategies: PubMed Clinical Queries: With MeSH database: Identify the correct MeSH terms via MeSH database and search for these. Go to History and find the number of the MeSH search. Go to Clinical Queries and put in the number of the MeSH search. Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 5. Exercise 3 - Suggested solutions Question: In patients with a suspected lower limb deep venous thrombosis, does the presence of Homan's sign accurately diagnose a deep vein thrombosis? 1. Patient/problem Patients with a suspected lower limb deep venous thrombosis 2. Intervention or Exposure Homan's sign 3. Comparison 4. Outcome Accurate diagnosis of deep vein thrombosis What type of question is this? Diagnosis Prognosis Etiology Therapy Experience Which search terms should be used? Use the PICO model to note all relevant search terms. Make sure to include all synonyms. It is not always necessary or smart to search for all the different parts of the question, decide which parts are essential. P I C O Patient/problem Intervention/exposure Comparison Outcome homan’s sign deep vein thrombosis dvt venous thrombosis Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 6. Suggested search strategies: PubMed Clinical Queries: Narrow, specific search will produce 0 results. Broad, sensitive search gives av few results. Search for Homan’s sign in MeSH database gives no hits, therefore you have to use text words. Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 7. Exercise 4 – Suggested solutions: Question: Is paracetamol effective for reducing fever in children? 1. Patient/problem Child with fever 2. Intervention or Exposure Paracetamol 3. Comparison 4. Outcome Reduction of fever What type of question is this? Diagnosis Prognosis Etiology Therapy Experience Which search terms should be used? Use the PICO model to note all relevant search terms. Make sure to include all synonyms. It is not always necessary or smart to search for all the different parts of the question, decide which parts are essential. P I C O Patient/problem Intervention/exposure Comparison Outcome paracetamol child acetaminophen fever acetamidophenol hyperthermia hydroxyacetanilide pyrexia panadol acamol acetaco anacin datril algotropyl acephen tylenol Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 8. Suggested search strategies: The Cochrane Library: PubMed Clinical Queries: With MeSH database: Identify the correct MeSH terms via MeSH database and search for these. Limit to All child 0-18 years. Go to History and find the number of the limited MeSH search. Go to Clinical Queries and put in the number of the MeSH search. Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 9. Exercise 5 – Suggested solutions: Question: Is acupuncture more effective than nicotine replacement therapy for smoking cessation? 1. Patient/problem Smokers 2. Intervention or Exposure Acupuncture 3. Comparison Nicotine replacement therapy 4. Outcome Smoking cessation What type of question is this? Diagnosis Prognosis Etiology Therapy Experience Which search terms should be used? Use the PICO model to note all relevant search terms. Make sure to include all synonyms. It is not always necessary or smart to search for all the different parts of the question, decide which parts are essential. P I C O Patient/problem Intervention/exposure Comparison Outcome acupuncture nicotine replacement smoking cessation nicotine gum nicotine patch Finding Evidence Based Clinical Information in The Cochrane Library and PubMed. EAHIL CEC June 2008 Hilde Strømme. Ullevaal University Hospital, Medical Library
  • 10. Suggested search strategies: The Cochrane Library: Combining smoking cessation AND acupuncuture AND nicotine replacement (search #4) will produce just a few RCTs. In this case it might be more appropriate to combine the intervention (acupuncture) and comparison (nicotine replacement) with OR (search #5) and then combine this with the outcome (smoking cessation) as in search #6. This will produce several systematic reviews. Two relevant titles: Nicotine replacement therapy for smoking cessation Acupuncture and related interventions for smoking cessation Maybe you will find the answer to your question by reading, appraising and comparing these two. PubMed Clinical Queries: With MeSH database: Identify the correct MeSH terms via MeSH database and search for these. In this case there is no MeSH term for nicotine replacement. A possible solution is to do a text word search for the relevant synonyms for nicotine replacement and then combine this with the MeSH terms for acupuncture and smoking cessation. Note: The MeSH term Acupuncture is about the dicipline (those performing acupuncture therapy) while Acupuncture therapy is the actual treatment. In this case the combination of smoking cessation, acupuncture and nicotine replacement only gives 7 hits. No point in taking it to Clinical Queries.
