Inspire. Lead. Engage. Laura Banfield, Nursing Librarian Health Sciences Library September 2010 Introduction to Evidence- Informed Decision Making (EIDM)

Inspire. Lead. Engage. Review the definition of Evidence (Informed) Based Practice and the steps in the process Formulate questions using PICO and PS models Introduce the concept of preprocessed evidence and the hierarchy of evidence Identify databases and sources for locating pre- processed evidence Learning Objectives

Inspire. Lead. Engage. “The integration of best research evidence with clinical expertise and patient values to facilitate clinical decision making” (Sackett et al., 2000) Evidence-Informed Decision Making (EIDM)

Inspire. Lead. Engage. Clinical state, setting, and circumstances Patient preferences and actions Research evidence Health care resources Clinical Expertise Clinical Decisions

Inspire. Lead. Engage. 1.Construct a relevant, answerable question from a clinical case. 2.Search the literature to retrieve the best evidence. 3. Critically appraise the literature (evidence) for validity and applicability. 4. Apply the evidence to your clinical practice. 5.Evaluate the outcome or performance. *From: Flemming, K. (1998). Asking answerable questions. Evidence-Based Nursing, 1(2), Steps of EIDM

Inspire. Lead. Engage. Two Types of Clinical Questions: 1. Background 2. Foreground Asking Clinical Questions

Inspire. Lead. Engage. Background questions are: general in nature address gaps in background knowledge examples include: pathophysiology, or risk factors of a disease; an overview of a nursing theory Foreground questions are: focused on the particular patient scenario, and ask for specific knowledge to manage the patient Background & Foreground Questions

Inspire. Lead. Engage. Background questions Need to be answered first Can be answered by books or general Websites Foreground questions Need to be very focused Can be answered by searching journal databases Background & Foreground Questions

Inspire. Lead. Engage. Examples of Background questions: What is the mechanism of action of insulin? How do you conduct a neurological assessment? Examples of Foreground questions: Is exercise more effective than a low-fat diet in reducing blood pressure in hypertensive patients? Is there a relationship between cell phone use in adults and the incidence of brain tumors? Background & Foreground Questions

Inspire. Lead. Enga ge. Two Major Research ‘Categories:’ Quantitative Research & Qualitative Research

Inspire. Lead. Enga ge. Two Major Research ‘Categories’ Quantitative Research is an “objective, systematic process to describe and test relationships and, examine cause and effect interactions among variables” (Burns & Grove, 1993, p. 777) Qualitative Research is a systematic, subjective approach used to describe life experiences and give them meaning” (Burns & Grove, 1993, p. 777)

Inspire. Lead. Engage. Goal is the discovery of relationships, or causation (cause & effect). Based on scientific method (hypothesis formation and testing) Many quantitative designs compare two or more groups Often involves an element of control Objectivity (related to measurement) Collection of data (numerical) and analysis via statistics Burns & Groove, 1993; Roberts & Burke, 1989 Quantitative Research

Inspire. Lead. Engage. Studies focus primarily on one of the following: Therapy/Treatment/Intervention; Prevention and Control – Effectiveness Etiology/Causation/Harm Prognosis – Outcome Diagnosis and Screening/Assessment Economics Quantitative Research Studies

Inspire. Lead. Engage. Quantitative research designs (studies) include: Randomized Controlled Trials (RCTs) Cohort Study (Cohort Analytic) Case-Control Study Cross-Sectional Study (survey) Case Report or Study Greenhalgh, 1997 Quantitative Research Designs

Inspire. Lead. Engage. (Quantitative) P -- Population/Situation I --Intervention/Exposure C -- Comparison/Counter Exposure O --Outcome Formulating the Question

Inspire. Lead. Engage. Intervention Is exercise more effective than rest for relieving chronic back pain? Question

Inspire. Lead. Engage. Population Intervention Comparison Outcome Question People with back pain Exercise Bed rest Reduced pain

Inspire. Lead. Engage. Causation Does the presence of hand sanitizer stations in nursing homes reduce the number of infections transferred to residents? Question

Inspire. Lead. Engage. Population Exposure Comparison Outcome Question Nursing home residents Hand sanitizer stations No hand sanitizer Reduced infection

Inspire. Lead. Engage. Aim is to discover meaning or gain understanding of a phenomena Investigates a phenomena in-depth Roberts & Burke (1989) Qualitative Research

Inspire. Lead. Engage. How people feel or experience a certain situation or circumstance Sampling of a small group of people Data collected via in-depth unstructured interviews, observation, focus groups, diaries Analysis of findings in narrative format Qualitative Research

Inspire. Lead. Engage. Examples of qualitative research designs include: Phenomenology Examine the ‘lived experience” of individuals experiencing a phenomena Grounded Theory Goal is to understand a social-psychological process and develop a theory Ethnography Study of a group or culture within their own setting Qualitative Research

Inspire. Lead. Engage. Formulating the Question (Qualitative) P -- Population S -- Situation

Inspire. Lead. Engage. How do people with HIV/AIDS living in a rural community feel about disclosing their status to their health care provider? Question

Inspire. Lead. Engage. Population Situation Question People with HIV/AIDS Disclosing their status to their health care providers

Inspire. Lead. Engage. Hierarchy of Pre-processed Evidence (Haynes, 2007)

Inspire. Lead. Engage. Support clinical decision making through linking all relevant best research evidence about a clinical situation directly to a patient’s record. (Haynes 2008) Sources of Systems Integrative Electronic Patient Records Systems

Inspire. Lead. Engage. “Summaries integrate best available evidence from lower layers … to provide a full range of evidence concerning management options for a given health problem.” (Haynes, 2007) Sources of Summaries Clinical Practice Guidelines Evidence Based Texts Summaries

Inspire. Lead. Engage. Consolidate the literature on a specific topic: comprehensive identification of studies review of study relevance evaluate methodologic quality extraction and analysis of data draw of conclusions Sources of Synthesis The Cochrane Library Health Care Journals Syntheses: Systematic Reviews

Inspire. Lead. Engage. Synopses “Synopses of individual studies or systematic reviews encapsulate the key methodologic details and results required to apply the evidence to individual patient care.” (Haynes, 2001) Sources of Synopses Database of Abstracts of Reviews of Effects (DARE) health-evidence.ca Evidence-based abstraction journals

Inspire. Lead. Engage. Single Studies are used: To keep up with the literature To update summaries and systematic reviews To contribute to clinical decisions if no higher preprocessed level is available Sources of Single Studies CINAHL Medline Single Studies
