Rese method workshop 2010

  1. 1. Introduction•Paradigm shift from expert or opinionbased practice to Evidence-basedpractice.•Has potential to increase patients’involvement in clinical decisionmaking.To improve health outcomes.
  2. 2. INTRODUCTION T he concept of EBP emer ged out of the Evidence-Based Medicine (EBM) movement, which is rooted in the wor k of A.L. Cochrane. In the 1970s, Cochrane stronglyencouraged his colleagues to use evidence from random controlled trials to deter mine the ef fectiveness and ef ficiency of medical inter ventions (T he Cochrane Collaboration, 2002).
  3. 3. Evidence-based practice(EBP) Is the acknowledgement of uncertainty followed by the seeking, appraising and implementation of new knowledge. It enables us to accept the difference, possibly more effective, methods of care than those currently employed.
  4. 4. Evidence-based nursing"Evidence-based nursing (EBN)means using the best availableevidence from research, along withpatient preferences and clinicalexperience, when making nursingdecisions."
  5. 5. Evidence Based Nursing  Evidence Based Nursing is the process by which nurses make clinical decisions using the best available research evidence, their clinical expertise and patient preferences.  Three areas of research competence are: interpreting and using research, evaluating practice, and conducting
  6. 6. Model for clinicaldecisions Patients preferences ResearchResources evidence Clinical Expertise
  7. 7. T he EBP- processEvidence-Based Practice is a five- step process: Identify a knowledge need and for mulate an answerable clinical question Locate the best available evidence Critically evaluate the evidence Inte grate the evidence with patient’s unique biology ,preferences and values Evaluate the outcome
  8. 8. Steps in EBN•Select a topic•Collect appropriate and accurate data to generateevidence for nursing practice.•Analyze data from clinical practice.•Design interventions based on evidence.•Predict and analyze outcomes.•Examine patterns of behavior and outcomes.•Identify gaps in evidence for practice.•Evaluate project to determine and implement bestpractices

  19. 19. Professional practice model
  20. 20. Evidence-based practiceThe quality of the evidence is based on: Is this the best available evidence? Best sources included peer reviewed journals & reports no more than 3-5 years old. Will the recommendations work for my practice to solve the client’s problems? Do the recommendations fit well with the preferences & values of the clients the nurse commonly works with?
  21. 21. Disciplined clinical inquiry modelPhase I-Needs assessmentPhase 2- learning and knowledgegenerationPhase 3- knowledge assimilationPhase 4 –knowledge applicationPhase 5- Outcomes & impact evaluation

  23. 23. Nursing practices are examined for: • Feasibility which relates to the practicality of implementing the action. •Appropriateness refers to whether it is acceptable & justifiable with in ethical guidelines. •Meaningfulness provides the rationale for the practice being adopted. •Effectiveness relates to how much evidence supports the practice & what evidence provides divergent view points
  24. 24. Benefits of using evidencebase for clinical practice: A sound foundation for practice Enhanced self-confidence, autonomy, critical thinking skills and professional self-concept Cost-effective patient care Increased job satisfaction &quality of care
  25. 25. BENEFITS cont’d.. Improved patient outcomes A stimulus for collaborative practice, retention & recruitment An improved image of nursing An ever –increasing scientific nursing knowledge base
  26. 26. What Data Do We Need forEvidence-Based Practice?•Information about the patient•Domain information and knowledge(“the evidence”) from systematicinquiry and other sources  
  27. 27. Informatics Supports•Building the evidence•Retrieving the evidence•Analyzing the evidence•Applying the evidence   
  28. 28. A successful EBP programrequires:(a) consistent long-term vision and support from senior leadership;(b) resources such as trained personnel, finances, and time; and(c) structured approach to create an environment that facilitates the process.
  29. 29. Criticisms of the evidence –based approach•Health professionals are already doing it•Evidence –based health care is ‘’cookbook’’ health care•Evidence –based practice relies on RCT&Meta -analyses•There is no evidence•Theory is more important than evidence inguiding practice
  30. 30. Challenges to EBP•Resistant to changes in nursingpractice.•Ability to critically appraise researchfindings.•Time, workload pressures, andcompeting priorities.•Lack of continuing educationprograms.•Fear of "stepping on ones toes"•Poor administrative support .
  31. 31. Challenges to EBP-cont’d•Relevant research based evidencebases are not comprehensive( there is gap in the practice)•The relevant evidence bases arenot static•Life long-learning is generallyaccepted as an important priority inthe 21 st century
  32. 32. Challenges to EBP-cont’d•The piece of research conducteddoes not mean that the finding sshould be transferred directly in tothe clinical setting•Demands from patients for a certaintype of treatment
  33. 33. Challenges to EBP-cont’d•Peer pressure to continue withpractices that are stepped intradition•Inadequate content and behavioralskills regarding EBP in educationalprograms•Lack of commitment and computerskills
  34. 34. Facilitating conditions toenhance EBP•Support and encouragement fromadministration•Time to critically appraise studies andimportant findings•Clearly written research reports•Adequate resources and time•Characteristics of health care team(sharedvision & mission)•Guideline characteristics

  44. 44. Best evidence contd…. RCTs (19 studies) to evaluate the effectiveness of nurse delivered smoking cessation intervention for adults, had >2 groups & had > 6 months of follow-up. At longest follow up, pts’ who received advice from a nurse were more likely to stop smoking than received usual care.
  45. 45. Best evidence cont’d..   RCT to compare the effectiveness and cost-effectiveness of aggressive versus symptomatic therapy in established rheumatoid arthritis(2005). The finding reported that there was no significant difference between the groups for any of the clinical outcome measures.
  46. 46. Best evidence cont’d… Research makes a difference in practice. A meta-analysis designed to determine the contribution of research-based practice to patient outcomes. Heater & Colleagues reported that patients who receive research based nursing care make “sizable gains” compared to those receiving routine nursing care.
  47. 47. Best Evidence cont’d.. Interventions involving family care givers to improve outcomes of hospitalized elders; the finding of studies suggest that family member involvement has benefits for both the elder and the family members.
  48. 48. Summary•Evidence based nursing started in the1800s with Florence Nightingale.•EBN is a problem solving approach toclinical decision making.•EBN integrates providers clinicalexpertise with the best external clinicalevidence.
  49. 49. Summary-cont’dEBN is the process of integrating • Clinical knowledge • Judgement • Proficiency skills • with the best available clinical evidence, such as nursing practice in to patient care (TRIP &GRIP).
  50. 50. Conclusion•A commitment to the continuedpreparation of nurses as scientist is vitalto achieve excellence in nursing practice•we can continue to shape the future ofnursing and healthcare...through theplanning, implementation anddissemination of quality research studies.
