  1. 1. LIBRARY RESOURCES EVIDENCE BASED PRACTICE CLINICAL NURSE FELLOWSHIP PROGRAM Michelle DeMars Health Sciences Librarian Michelle.DeMars@csulb.edu
  2. 2. BY THE END OF THIS SESSION YOU WILL: • Be able to identify the 5 stages of Evidence Based Practice • Identify and develop PICOT questions • Use keywords from your question to search the databases • Refine search: limiters, Boolean operators, synonyms • Know how to locate journal articles in databases • Evaluate your results to find the best evidence available
  3. 3. THE 5 STAGES OF EVIDENCE BASED PRACTICE ASK FIND EVALUATE APPLY REVIEW
  4. 4. ASK: DEVELOP A CLEARLY WORDED CLINICAL QUESTION USING PICO(T) The PICOT question format is a consistent "formula" for developing answerable, researchable questions. P: Population/disease ( i.e. age, gender, ethnicity, with a certain disorder) I : Intervention or Variable of Interest (disease, risk behavior, etc.) C: Comparison: (could be a placebo or alternative treatment) O: Outcome: (risk of disease) T: Time: The time it takes to demonstrate an outcome (e.g. the time it takes to achieve an outcome or how long participants are observed). Note: Not every question will have an intervention (as in a meaning question) or time (when it is implied in another part of the question) component.
  5. 5. PICO(T) A concerned new mother comes in with her premature infant. She is concerned about the baby’s weight gain and growth. She wants to know if she should start feeding her baby formula or just continue with breastfeeding. Patient, problem or population Intervention Comparison Outcome Premature Infants Breastfeeding Formula Feeding Development/Growth
  6. 6. ASK YE SHALL FIND: DIFFERENT TYPES OF CLINICAL QUESTIONS & DIFFERENT TYPES OF STUDIES In addition to composing a well-built clinical question, one must keep in mind the type of question and the type of study that would provide the best evidence Most common types of questions Types of Studies Diagnosis How to select and interpret diagnositc tests Therapy How to select treatments that have more benefit than risk Prognosis How to estimate a patient’s clinical course over time Etiology How to identify causes for disease Remember the higher up you go on the pyramid the more rigorous the studies are and often have less bias.
  7. 7. FIND: SEARCHING FOR THE EVIDENCE • Use keywords from your PICOT question to search the databases • Determine the level of evidence that best answers the question • Select relevant databases to search • Refine search: subject headings, Boolean operators, limit your results
  8. 8. SEARCH AND EVALUATEUse Databases like PubMed, CINAHL and Cochrane to find the best evidence
  9. 9. TODAY WE LEARNED To identify the 5 stages of Evidence Based Practice • To identify and develop PICOT questions • To use keywords from your question to search the databases • To refine search: limiters, Boolean operators, synonyms • To know how to locate journal articles in databases • To evaluate your results to find the best evidence available
