- 1. Finding the Evidence Determiningwhat is a good research article
- 2. Where do youlook for articles? • Google? • Remember to use searching techniques
- 3. Where do youlook for articles? • Look for where and how the information was created as well as where the information was shared to evaluate the usefulness of the information (Information has value) • Specific websites like • WebMD • Medlineplus • MayoClinic • Plus – these are consumer health websites • Con – Not the original research! • Let’s look at an example – article
- 4. Selecting keywords forsearching •Go to this website: •https://padlet.com/ckoman/mazur •Enter the keywords you feel would help you find the original article
- 5. Finding the originalresearch • What can we learn from this article? • Who is the author? • What is the source of the article? • Is this original research? • Is there a citation indicating where the information came from? • You locate this through the library databases!
- 6. Suggested keywords • Researchis iterative and depends upon asking increasingly complex or new questions whose answers in turn develop additional questions or lines of inquiry in any field. (Research as Inquiry) • Asthma • Obstructive Sleep Apnea • OSA • JAMA – January 13 issue • MihaelaTeodorescu • Wisconsin Sleep Cohort Study • adult employees of state agencies, 30 to 60 years of age • Participants with preexisting asthma had a nearly 40 percent increased risk for new OSA compared with those without asthma • Study
- 7. Where to findresearch articles? • PubMed • MedLine with Full-text • CINAHL with Full-text
- 8. Types of ResearchArticles • Review • Clinical Guideline • Case Report • Cohort Study • Randomized ControlledTrials - RCT • Systematic Review • Meta-analysis
- 9. What does itall mean? • Review • A review of the literature • Can be from a certain date • Can be for a certain time period • Excellent for a review of a topic • Different then a Systematic Review • Place to find: PubMed, Medline with Full-text • ClinicalGuideline • The gold standard in treatment for a particular disease • Used to be: National GuidelineClearinghouse • Try this source: Evidence-based Practice Center Reports from AHRQ • Case Report • Report on a patient • Case Series / Case Control Study • Reports on a series of patients with the desired outcome • Patients with the desired outcome and those without – comparing them • Place to find: PubMed, Medline with Full-text
- 10. What does itall mean? • Cohort Study • Two groups (cohorts) of patients one which did not receive the exposure of interest and one which did • Both groups are followed for desired outcome • The main feature of cohort study is observation of large numbers over a long period (commonly years) with comparison of incidence rates in groups that differ in exposure levels. • Place to find: PubMed, Medline with Full-text • Randomized ControlledTrial • Patients are randomized into a control group or in an experimental group; both groups are followed for outcomes • Place to fine: PubMed, Medline with Full-text
- 11. What does itall mean? • Systematic Review • The application of strategies that limit bias in the assembly, critical appraisal, and synthesis of all relevant studies on a specific topic. Systematic reviews focus on peer-reviewed publications about a specific health problem and use rigorous, standardized methods for selecting and assessing articles. A systematic review may or may not include a meta-analysis, which is a quantitative summary of the results • Place to find: PubMed, Medline with Full-text • Meta-Analysis • A systematic review using qualitative methods to summarize the results • Place to find: PubMed, Medline with Full-text
- 12. Locating specific articlesin the library databases • Objective: Searching for information is often non-linear and iterative, requiring the evaluation of a range of information sources and the mental flexibility to pursue alternate avenues as new understanding develops • PubMed and Medline with Full-text • Advanced search • Look for the author • Look for the publication type – type of research article • Look for the journal name • Look for the main subject of the article (MeSH term) • Basic search • Use limits

- 18. Exercise • Pair upinto groups of 2 • I am going to hand out articles • Each person in the group will look for the original research • One person will use PubMed • One person will use MedLine with Full-Text • Then switch databases • the person who searched PubMed will now search MedLine with Full-Text and the person who searched MedLine with Full-text will now search PubMed • Re-group as a whole and discuss findings
