Transcript of "Searching For The Evidence"

  1. 1. Searching for the Evidence DNP BOUND
  2. 2. Evidence Based Practice <ul><li>What is EBP? </li></ul><ul><ul><li>Most commonly cited definition is “the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.” </li></ul></ul><ul><ul><ul><ul><li>Sackett, et al. </li></ul></ul></ul></ul>
  3. 3. The EBP cycle <ul><li>Identify/define the problem </li></ul><ul><li>Formulate a focused clinical question </li></ul><ul><li>Identify the appropriate resources </li></ul><ul><li>Search for valid and relevant information </li></ul><ul><li>Critically appraise/review this information </li></ul><ul><li>Implement in practice </li></ul><ul><li>Clinical audit </li></ul>
  4. 4. Formulate a Question <ul><li>Ask a focused, answerable question: </li></ul><ul><li>NOT </li></ul><ul><li>Are febrile seizures in babies dangerous? </li></ul><ul><li>INSTEAD </li></ul><ul><li>Does a febrile seizure in a 6- month old infant increase the likelihood that s/he will develop epilepsy? </li></ul>
  5. 5. Formulate a Question <ul><li>What is the effect of ( the Intervention or predictor variable) </li></ul><ul><li>On ( the Outcome or given characteristic) </li></ul><ul><li>For ( the group or patient characteristics) </li></ul>
  6. 6. Formulate a Question <ul><li>Use the PICO framework: </li></ul><ul><li>P – patient/problem </li></ul><ul><li>I – intervention </li></ul><ul><li>C – comparison </li></ul><ul><li>O – outcome </li></ul>
  7. 7. P <ul><li>Population </li></ul><ul><li>Disease or condition </li></ul><ul><li>Stage of disease </li></ul><ul><li>Gender </li></ul><ul><li>Age group </li></ul><ul><li>Socioeconomic group </li></ul><ul><li>Healthcare setting </li></ul>
  8. 8. I <ul><li>Intervention </li></ul><ul><li>What is being done? </li></ul><ul><li>Drug therapy, surgery, radiotherapy </li></ul><ul><li>Level of intervention: frequency, dosage </li></ul><ul><li>Stage of intervention: prevention, secondary prevention; advanced </li></ul><ul><li>Delivery of intervention: self-medication etc. </li></ul>
  9. 9. C <ul><li>Comparison </li></ul><ul><li>What could be done instead? </li></ul>
  10. 10. O <ul><li>Outcome </li></ul><ul><li>What happened to P as a result of I? </li></ul><ul><li>Patient oriented: quality of life; reduction in severity of symptoms; adverse effects </li></ul><ul><li>Provider oriented: cost-effectiveness </li></ul>
  11. 11. Is acupuncture effective in inducing labor? P Pregnant, >40 weeks, age? I Acupuncture: duration of treatment, frequency C No intervention O + - onset of labor? - adverse effects?
  12. 12. Exercise or antidepressants for depression? P Depression: severity? Socioeconomic factors; healthcare setting I Exercise: how strenuous? How often? C Antidepressants: type? Dose? Frequency? Duration? O + Cure? Symptom reduction? Quality of life? -Adverse effects
  13. 13. What is Evidence? <ul><li>Hierarchy of research evidence </li></ul><ul><ul><li>Systematic reviews </li></ul></ul><ul><ul><li>Randomized controlled trials </li></ul></ul><ul><ul><li>Non-randomized controlled trials </li></ul></ul><ul><ul><li>e.g. cohort studies, case-control studies </li></ul></ul><ul><ul><li>Consensus statements from respected authorities </li></ul></ul><ul><ul><li>Individual/expert knowledge </li></ul></ul><ul><ul><li>Anecdotal evidence </li></ul></ul>
  14. 14. Finding the Evidence <ul><li>Where is the evidence? </li></ul><ul><li>New generation EBP resources </li></ul><ul><ul><li>e.g. The Cochrane Library </li></ul></ul><ul><li>Large scale, traditional databases </li></ul><ul><ul><li>e.g. MEDLINE, CINAHL </li></ul></ul>
  15. 15. Resources <ul><li>Primary Databases </li></ul><ul><ul><li>CINAHL </li></ul></ul><ul><ul><li>MEDLINE </li></ul></ul><ul><ul><li>Cochrane Library </li></ul></ul><ul><li>Point of Care/Clinical </li></ul><ul><ul><li>DynaMed </li></ul></ul><ul><ul><li>Essential Evidence Plus </li></ul></ul>
  16. 16. Resources <ul><li>Search Engines </li></ul><ul><ul><li>SUMsearch </li></ul></ul><ul><ul><li>TRIP database </li></ul></ul><ul><li>Guidelines </li></ul><ul><ul><li>National Guideline Clearinghouse </li></ul></ul>
  17. 17. Medical vs. Nursing Concerns <ul><li>Medical </li></ul><ul><ul><li>Abnormalities of joint ( Xrays, tests) </li></ul></ul><ul><ul><li>Medication </li></ul></ul><ul><ul><li>Surgical intervention </li></ul></ul><ul><li>Nursing </li></ul><ul><ul><li>Prevention </li></ul></ul><ul><ul><li>ADLs </li></ul></ul><ul><ul><li>Pain </li></ul></ul><ul><ul><li>Sleep problems </li></ul></ul>
  18. 18. EBP Search Demonstration <ul><li>Subject Headings </li></ul><ul><li>EBP Filters </li></ul><ul><li>Limiters </li></ul><ul><li>Question: </li></ul><ul><li>What should the NP do to prevent pressure ulcers in the elderly? </li></ul>
  19. 19. EBP Search Strategy <ul><li>What is the effect of Nursing Care/Intervention –Intervention is the predictor variable </li></ul><ul><li>On – Preventing pressure ulcers – this is the given characteristic or outcome </li></ul><ul><li>For – the elderly – the specific group of patients or population characteristic </li></ul>
  20. 20. Subject Headings <ul><li>Specific words or phrases selected from a controlled vocabulary that describe a work </li></ul><ul><ul><li>MEDLINE = MeSH </li></ul></ul><ul><ul><li>CINAHL = CINAHL Headings </li></ul></ul>
  21. 21. Research Filters <ul><li>Research filters are pre-designed search strategies </li></ul><ul><li>Useful for finding the right kind of research within large databases </li></ul><ul><ul><li>ADEPT: Clinical questions are usually about Diagnosis, Aetiology, Prognosis, Therapy </li></ul></ul><ul><ul><li>Clinical Queries in MEDLINE </li></ul></ul><ul><ul><li>Netting the Evidence – EBP pages </li></ul></ul>
  22. 22. Limiters <ul><li>Parameters for your search </li></ul><ul><ul><li>MEDLINE limiters include: </li></ul></ul><ul><ul><ul><li>Age group </li></ul></ul></ul><ul><ul><ul><li>Publication type </li></ul></ul></ul><ul><ul><ul><li>Language </li></ul></ul></ul><ul><ul><ul><li>Dates </li></ul></ul></ul>
