  1. Evidence-Based Practice and the Future of Nursing Suzanne Prevost, RN, PhD Associate Dean for Practice University of Kentucky College of Nursing President-Elect – Sigma Theta Tau International

  2. The Evolution of Evidence-Based Practice

  3. What is - Evidence? Anything that provides material or information on which a conclusion or proof may be based; used to arrive at the truth, used to prove or disprove the point at issue. (Webster)

  4. Evidence-Based Practice • Evidence-Based Practice – Conscientious, explicit and judicious use of current best evidence with clinical expertise, and patient values to make decisions about the care of patients. (Sackett, 2000) • Evidence-based nursing practice is the process of shared decision-making between practitioner, patient and significant others, based on research evidence, the patient’s experiences and preferences, clinical expertise, and other robust sources of information. (STTI , 2007)

  5. EBP is both a process and a product… requiring that the evidence which is produced – is also applied to practice. (D. Rutledge, 2002)

  6. Evolution of EBP • 1991 – Evidence-based medicine -first described in the American College of Physicians Journal Club. • 1992 – the Evidence-based Medicine Working Group described it as a “paradigm shift” in JAMA • Clinical observations and experience, principles of pathophysiology, knowledge gained from authoritative figures, and common sense -- are no longer a sufficient guide for clinical practice, decision-making, or the development of practice guidelines

  7. Evolution of EBP • Early 1990’s – US Prev. Services TF – began developing EB Guidelines for Screening and Prevention • 1992 – AHCPR (now AHRQ) – started publishing systematic reviews and consensus statements in the form of Clinical Practice Guidelines, starting with the guideline for Acute Pain, 19 guidelines were produced from ’92-’96 • 1993 - the first annual Cochrane Colloquia was held at the New York Academy of Sciences • 1993 – Online Journal of Knowledge Synthesis for Nursing

  8. Evolution of EBP 1997 – Jan 2011 – 198 Evidence Reports published by the EBP centers • May, 2005 – Episiotomy Use • “…no health benefits from episiotomy…routine use is harmful …”

  9. Recent Evidence Reports 193. Alzheimer's Disease and Cognitive Decline192. Lactose Intolerance and Health190. Enhancing Use and Quality of Colorectal Cancer Screening189. Exercise-induced Bronchoconstriction and Asthma188. Impact of Consumer Health Informatics Applications187. Treatment of Overactive Bladder in Women185. Management of Ductal Carcinoma in Situ (DCIS)184. Treatment of Common Hip Fractures151. Nurse Staffing and Quality of Patient Care140. Tobacco Use: Prevention, Cessation, and Control This is just one example of literature syntheses that are available to support EBP.

  10. Nurse Staffing and Quality of Patient Care • Objectives: To assess how nurse to patient ratios and nurse work hours were associated with patient outcomes in acute care hospitals • Results: Higher RN staffing was associated with less mortality, failure to rescue, cardiac arrest, hospital acquired pneumonia, and other adverse events. Limited evidence suggests that the higher proportion of RNs with BSN degrees was associated with lower mortality and failure to rescue. More overtime hours were associated with an increase in hospital related mortality, nosocomial infections, shock, and bloodstream infections.

  11. Evolution of EBP • 1998 – Evidence-Based Nursing journal debuted • 1999 – The UK Department of Health stipulated that, to enhance the quality of care, nursing, midwifery, and health visiting practice must be evidence-based • 2002 - JCAHO begins requiring monitoring of evidence-based core measures • 2004 – WorldViews on Evidence-Based Nursing • 2004 – AACN began publishing “Practice Alerts”

  12. Evolving Interest in Evidence-Based Practice 2011 – Medline search > 38,000

  13. Within one decade, the concept of evidence-based practice has evolved and been embraced by nurses in nearly every clinical specialty, across a variety of roles and positions, and in locations around the globe. EBP – means many things to many people

  14. Factors Contributing to Emphasis on Evidence-Based Nursing Practice • Scientific knowledge expansion • Knowledge expands exponentially q 2 yrs • 12 yrs. from now – 128 x as much knowledge • Knowledge availability -- The Internet • Highly educated nurses in clinical settings • APNs – focusing on evidence-based clinical problem-solving • Clinical Nurse Researchers • DNP Movement

  15. Factors Contributing to Emphasis on Evidence-Based Nursing Practice • Aggressive pursuit of cost-effectiveness • Focus on quality of care, Risk & error reduction • Highly educated consumers • JCAHO/Accreditation expectations • Increased attention to institutional image • Magnet hospital movement

  16. Most nurses agree that EBP is important… but how do we make it happen?

  17. What is the 1st step toward EBP for the practicing nurse? • Asking good clinical questions • Nurses must be empowered to ask critical questions in the spirit of looking for opportunities to improve nursing care and patient outcomes • Risk-taking environment

  18. Nursing vs. Medical Questions • Often more exploratory • Less frequently focused on intervention selection • Less evidence to support many nursing interventions • Most nursing interventions have less capacity for harm • Many nursing challenges often go beyond individual clinical interventions (e.g. nurse staffing, education, recruitment)

  19. Clinical Nursing Questions • In postoperative patients, does prn or ATC analgesic administration yield better pain relief? • Among critically ill patients, is controlled or open visitation more effective in reducing patient anxiety?

  20. Questions for APNs • In acute care hospitals, is the CNS more effective by focusing on a specific patient population or a specific unit? • What else?

  21. What kind of questions might the Nurse Manager ask? • On medical-surgical units, do 12 hour or 8 hour shifts result in more medication errors?

  22. Key Questions to Ask When Considering EBP • Why have we always done “it” this way? • Do we have evidence-based rationale? • Or, is this practice merely based on tradition? • Is there a better (more effective, faster, safer, less expensive, more comfortable) method? • What approach does the patient (or the target group) prefer? • What do experts in this specialty recommend?

  23. Key Questions to Ask When Considering EBP • What methods are used by leading/benchmark, organizations? • Do the findings of recent research suggest an alternative method? • Are organizational barriers inhibiting the application of best practices in this situation? • Is there a review of the research on this topic? • Are there nationally recognized standards of care, practice guidelines, or protocols that apply?

  24. Steps in the EBP Process • Developing a well-built question • Finding evidence-based resources to answer the question • Evaluating the strength and applicability of the evidence • Applying the evidence to practice • Evaluating the effects

  25. Once we agree upon the question that poses an opportunity for improvement, then we must find the evidence • Where should we look? • Are all forms of evidence equivalent in quality?

  26. Strength of Evidence • Level I - meta-analysis of multiple studies • Level II - experimental studies, RCTs • Level III - quasiexperimental studies • Level IV - nonexperiemental studies • Level V - case reports, clinical examplesAHCPR/AHRQ • At what level is most nursing evidence?

  27. AACN Levels of Evidence (Armola, et al. , C C Nurse, 2009) Meta-analysis or metasynthesis of multiple controlled studies, supporting a specific action Controlled, randomized, or nonrandomized studies, supporting a specific action Qualitative, descriptive or correlational studies or systematic reviews with consistent results Peer-reviewed prof. organ. standards with studies to support them Theory-based evidence from expert opinion or case studies Manufacturer’s recommendations only • Level A • Level B • Level C • Level D • Level E • Level M

  28. What constitutes the “Evidence” in Evidence-Based Practice? “Evidence-based practice has been defined as the use of the best clinical evidence from systematic research (referring to meta-analysis, integrated reviews, & RCTs – as the gold standard). …Others (often nurses) believe that experimental studies, observational studies, and correlational studies are also suitable evidence.” C. Goode, Applied Nursing Research, 2000

  29. University of Colorado Multidisciplinary Evidence-Based Practice Model • Emphasizes that all types of research can be evaluated for their contribution • Recognizes the use of 9 non-research sources of evidence: • Pathophysiology, Retrospective or Concurrent Chart Review, Quality Improvement or Risk Data, International and Local Standards, Infection Control Data, Clinical Expertise, Benchmarking Data, Cost-Effectiveness Analysis, and Patient Preferences

  30. A major dilemma for the practicing nurse: Finding the time, access, and research expertise that are needed to search and analyze the evidence to find answers to their clinical questions. For those of you who are already pursuing EBP, which of these issues pose the greatest challenges for you?

  31. Finding the Evidence • Don’t reinvent the wheel • If other experts have reviewed the evidence on your topic … start there

  32. Preprocessed Evidence (A. DiCenso, 2009)

  33. Resources to Support Evidence-Based Practice • Government agencies • Cochrane Collaboration • Professional Organizations • Benchmark Institutions

  34. AHRQ – Agency for Healthcare Research and Quality

  35. Cochrane Collaboration • “an international, independent, not-for-profit organization of over 27,000 contributors from more than 100 countries, dedicated to making up-to-date, accurate information about the effects of health care readily available worldwide. • Contributors produce systematic assessments of healthcare interventions, known as Cochrane Reviews, which are published online in The Cochrane Library. • Rely heavily on RCTs • Primarily focused on effectiveness of interventions, more medical and pharmaceutical than nursing

  36. Cochrane Collaboration

  37. Substitution of Drs by Nurses in Primary Care Objectives: to evaluate the impact on patient outcomes, processes of care, and costs. Outcomes included: morbidity; mortality; satisfaction; compliance; and preference. Studies were included if nurses were compared to doctors providing a similar primary health care service. Doctors included: general practitioners, family physicians, pediatricians, internists or geriatricians. Nurses included: nurse practitioners, clinical nurse specialists, or advanced practice nurses. Results: 4253 articles were screened, 25 articles met our inclusion criteria. No appreciable differences were found between doctors and nurses in health outcomes, processes of care, or cost; but patient satisfaction was higher with nurse-led care.

  38. Professional Nursing Organizations Supporting Evidence-Based Practice • AACN • AWHONN • AORN • ONS • Sigma Theta Tau

  43. Local vs. Global Evidence • Institutional/Local > National/International • CPI Data/Research Results • Standards & Protocols/Practice Guidelines • Expert Advice • Patient/Family Preferences

  44. Values and Preferences EBN - integration of the best evidence available, nursing expertise, and the values and preferences of the individuals, families and communities … Yasmin Amarsi, RNL, 2002: “The crux is to ensure that EBN attends to what is important to nursing and that caring is not sacrificed on the altar of scientific evidence.”

  45. Amy’s Blog • I consulted a well-regarded oncologist in New York. After the tests she regretfully informed me that my disease was not curable. She recommended an evidence-based course of medications aimed at slowing the progression. Before I committed, I wanted a second opinion. I secured an appointment with the pre-eminent researcher/ clinician in inflammatory breast cancer. … • The building was beautiful, the staff attentive. …I had no doubt that the care would be top-notch. • Everything changed when I sat down with the physician. He never asked about my goals for care. He recommended an aggressive approach of chemotherapy, radiation, mastectomy, and more aggressive chemotherapy. My doctor in New York had said this was the standard, evidence-based protocol for patients in Stage III B…But since I am in Stage IV (with mets) she said I wouldn’t get the benefit of this aggressive, curative approach.

  46. “All of my patients use this protocol,” he said. • I was shocked. “Does this mean I could get better?” I asked. • “No, this is not a cure.” he answered. “But if you respond to the treatment, you might live longer, although there are no guarantees.” • My goals are to maximize my quality of life so I can live, work, and enjoy my family … Would I undergo a year or more of grueling, debilitating treatment only to live with spinal fractures if the cancer progressed?  … Would I get the possibility of quantity and no quality? • I pressed him. “Why do the mastectomy? If the cancer has already spread to my spine. You can’t remove it.” • His brow furrowed. “Well, you don’t want to look at the cancer, do you?” He made it sound like cosmetic surgery. • Right now, I feel fine. I can work. I am pain free. Did I want to trade that for a slim chance of a little extra time (no guarantees, of course)?

  47. “But what about the side effects of radiation?” I asked. “I’ve heard they are terrible.” • He frowned and seemed annoyed by my questions. “My patients don’t complain to me about it,” he replied. • Inwardly, I shook my head. Of course his patients never complained to him. Most of them were probably unaware that less aggressive treatments were viable options. To me, there were real drawbacks. Undergo aggressive therapy that might buy me a longer life…at what cost? I might never recover my health for the limited period of time I have. • This doctor, top in his field, was reflecting the bias of our medical system towards focusing (evidence-based) survival. He was focused only on quantity and forgot about quality.
