  1. What is Evidence Based Practice Barbara Ann M. Messina, PhD, RN, ANPClinical Associate ProfessorSchool of Nursing – Department of Adult HealthAdjunct Clinical Associate ProfessorSchool of Medicine – Department Pharmacology

  2. Objectives • Define what is evidence based practice (EBP). • Discuss the history of EBP. • Implementing Evidence-Based Practice: The Iowa Model. • Discuss the Determination of Clinical Relevance in EPB. • Discuss how to Framing a Clinical Question using the PICO model. • Discuss the Literature Review and Search Techniques. • Define the AHRQ.

  3. What is EBP? The use of evidence-based practice (EBP) and national guidelines to improve the quality of patient care. EBP closes the gap between research outcomes and practice (Newhouse, Dearbolt, Poe, Pugh, & White, 2005)

  4. What is EBP? EBP uses current research evidence combined with clinical expertise and patient values to formulate sound interventions (DiCenso, Guyatt, & Clinska, 2005).

  5. History of EBP FFCM (1909-1988) in 1972. Dr. Cochran, a British epidemiologist, identified a gap between current practices and evidence-based guidelines.

  6. Implementing EBP:The Iowa Model The Iowa Model of EBP was developed by Marita G. Titler, PhD, RN, FAAN, Director Nursing Research, Quality and Outcomes Management, Department of Nursing Services and Patient Care, University of Iowa Hospitals and Clinics, Iowa City, Iowa Iowa Model: Considers the entire health care system: • Provider • Patient • Infrastructure

  7. Iowa Model • Identify a trigger – problem focused or knowledge focused • Determine clinical relevance – is it important to the organization or culture

  8. Framing the Clinical Question What to include what to exclude?

  9. PICO Model P = Who is the Patient Population? I = What is the potential Intervention or area of Interest? C = Is there a Comparison intervention or Control group? O= What is the desired Outcome? Your question drives your research!

  10. The Literature Review • Cochrane Library • Clinical Practice Guidelines • Cumulative Index to Nursing and Allied Health Literature (CINAHL); and • PubMed. http://www.hsclib.sunysb.edu/

  11. Types of Literature Reviews Systematic Review: Looks for similar Studies (Critiquing an Article) Meta Analysis: Statistical technique for averaging an effect of treatment across studies (Cochrane Data Base)

  12. Levels of Evidence

  13. Hierarchy of Evidence

  14. Hierarchy of Evidence Levels of Evidence Category I:  Evidence from at least one properly randomized controlled trial. Category II-1: Evidence from well-designed controlled trials without randomization. Category II-2: Evidence from well-designed cohort or case-control analytic studies, preferably from more than one center or research group. Category II-3: Evidence from multiple times series with or without intervention or dramatic results in uncontrolled experiments such as the results of the introduction of penicillin treatment in the 1940s. Category III: Opinions of respected authorities, based on clinical experience, descriptive studies and case reports

  17. Evaluating Evidence

  18. EBP(Medicine) United States: Agency for Health Care Policy and Research (AHCPR) • Department of Health & Human Services http://www.ahcpr.gov/ • Developed many clinical guidelines to direct the EBM movement.
