What is Evidence Based Practice? (EBP) Has its roots in Evidence-based Medicine: “the integration of best research evidence with clinical expertise and patient values” (Institute of Medicine, 2001, pg. 147) Includes a framework and a set of tools and resources for DOING EBP.
Psychology introduced EBPP in 2005 Best research available Clinical Expertise CD Patient characteristics, culture and preferences “The integration of the best available research with clinical expertise in the context of patient characteristics, culture, and preferences” (became policy of the American Psychological Association in August, 2005 – see American Psychologist, 2006, p. 273)
Best research available Clinical Expertise Clinical Expertise Patient characteristics, culture and preferences The framework Clinical Decision CD
The Framework of EBP Two Components of EBP Operationalization: 5 STEPS • Convert information needs into questions. • 2. Search for the best evidence in the literature. • 3. Critically appraise the evidence. • 4. Integrate with a patient’s characteristics, culture and preferences. • 5. Evaluate the outcome. Best research available CD Patient characteristics, culture, preferences Clinical Expertise
STEPS FOR DOING EBP Step 1: Formulate a clinical question Step 2: Acquire the evidence Step 3: Appraise the evidence Best research available
In EBP… The evidence ALONE is never enough. Best research available
Best research available Clinical Expertise Patient characteristics, culture and preferences One uses clinical expertise to integrate the evidence with the patient HOW? Is there anything about this particular patient that would make me question applicability of the evidence in this case? Clinical Decision CD
Patient characteristics, culture and preferences Clinical Expertise • Not opinion • The ability to use clinical skills and past experience to accurately assess patient's • situation • Values • Preferences • risks and benefits of interventions AND • One’s own ability to deliver an intervention Clinical Expertise Best research available CD

Psychology’s Focus • EBP is both a framework and a process • It includes a set of tools and resources for clinical decision making • Until recently, psychology has focused on the framework • Other disciplines (e.g., medicine, nursing, social work) have focused on the operationalization

Clinical decisions using EBP begin and end with the patient • We begin by asking specific questions relevant to our patient • We find the evidence • We evaluate the evidence • We consider our clinical expertise and patient characteristics • We make clinical decisions in collaboration with the patient • We evaluate the effectiveness of the entire process as it was applied to our patient
The 5-Step EBP Process • Convert information needs into a clear question. (Ask) • Search for the best evidence in the literature. (Acquire) • Critically appraise the evidence. (Appraise) • Integrate with a patient’s needs, preferences, circumstances, and values. • Evaluate the outcome.

Practical Tools and Resources for an Evidence-Based Practice
What are we Searching for? • The Type of Study you Want Depends on the Question you are Asking • Does Treatment A work better than Treatment B for Condition X? (RCT or systematic review) • Etiology Question: prospective or cohort studies
Categories of Studies • Systematic Reviews (synthesis of all available randomized controlled trials, meta-analyses offer quantitative estimates of effect sizes) • RandomizedControlled trials (randomization & control group is key) • Cohort studies (prospective – ID two groups of patients – “cohorts”, one that received exposure of interest, one that did not & follow these cohorts forward for outcome) • Case Control studies (retrospective- ID patients who have outcome of interest – “case” & those who do not & look back to see if they had the exposure of interest) • Case Studies/Case Series (Qualitative -several cases, follow long time) • Case Report (Qualitative – one in-depth case)
Databases that contain all of these: TRIP • Databases of systematic reviews • Cochrane 2. Evidence-based summaries: • Online EB text books • EB guidelines • ESTs • 3. Medline and PsycINFO • Specific EBP techniques UpTODate Clinical Evidence $$$$$
What if yourpatient is the one asking the question (or handing you a printout)?

The 5-Step EBP Process • Convert information needs into a clear question. (Ask) • Search for the best evidence in the literature. (Acquire) • Critically appraise the evidence. (Appraise) • Integrate with a patient’s needs, preferences, circumstances, and values. • Evaluate the outcome.
Caveats • All studies have flaws • You will never find the perfect study • You want to find the best available evidence • Knowing there is no good evidence is not the same as not knowing if there is evidence
When Appraising Randomized Controlled Trials: • F: Follow-up? • R: Randomization? • I: Intention to treat analysis? • S: Similar baseline characteristics? • B: Appropriate Blinding? • E: Equal treatment of groups?
One Way to Summarize… Comments In general, what was the quality of the research and how directly did it address your question? Clinical bottom line The available research suggests ….
43-year-old woman with 1-3 migraine headaches per week. • Otherwise healthy. • Stress is a significant trigger for her headaches, • Imitrex aborts her headaches most of the time, but she dislikes taking it because of the side-effects and cost. • She prefers “alternative” approaches • Has heard that acupuncture can help migraines.
The patient asks: • Should she pursue treatment with us or try an “alternative” approach such as acupuncture? • What do we think would be the most effective treatment for her?
The 5-step process: • Convert information needs into a clear question. • Search for the best evidence in the literature. • Critically appraise the evidence. • Integrate with a patient’s needs, preferences, circumstances, and values. • Evaluate the outcome.
Background Questions • What are the most effective treatments for chronic migraine headache? • Pharmacological • Non-pharmacological • Is acupuncture an effective treatment for migraine headache? • Are there any significant risks associated with acupuncture?
Foreground Questions P = I = C = O = In middle aged women with migraine headaches is there any evidence that acupuncture compared to sham treatment, biofeedback, relaxation training, and cognitive-behavioral therapy reduces the frequency, intensity, and/or duration of migraines?
