Balance Between Science and Practice - EBP requires a balance between scientific evidence and clinical judgment, allowing clinicians to make informed decisions while adapting to individual client needs and contexts. Booths 5-Step Process (2004) 1. Formulate the clinical question 2. Find available relevant published research evidence 3. Evaluate quality of research 4. Combine quality research findings with expertise, experience, client desires, & preferences 5. Evaluate the outcomes of treatment provided Step 1: Formulate the clinical question Will TX A work? Will TX b work? For which clients Will tx a or be more effective at achieving outcome X PICO ○ P: a type of patient or problem ○ I: intervention ○ C: a comparison or contrast to the intervention ○ O: an outcome Step 2: Find the research evidence: Systematic review, meta-analysis systematic reviews & meta-analysis: are the best; they are comprehensive, reliable, unbiased, identifies gaps, etc (best for evidence and will give evidence-based answers to clinical situations) Do NOT depend on textbooks unless they provide a thorough systematic review of research studies Internal validity: measures how well a study is conducted & how accuractely its results reflect the studied group External validity: realtes to how applicable the findings are in the real world Step 3: Evaluate the research evidence Assess the internal validity of the studies including its basic design, and then its external validity with respect to your client Must consider client characteristics and selection of outcome measure IDEAL several well constructed RCTs (randomized control trials) with consistent results, all with clients like yours summarized in one objective and comprehensive systematic review Step 4: Combine Research evidence, expertise, and clinical references to make a decision Quality research is the starting point Step 5: Implement and monitor Implement treatment, monitor to see if it is being done accurately and systematically Obtain objective measures of effect of Tx Be prepared to change course! It’s an art: the clinician’s ability to balance multiple, constantly changing sources of information What is the point of theories?Why do they matter? Theories synthesize (integrate) the facts into a coherent framework that explains them; and Theories suggest hypotheses/conjectures/predictions that can be tested Example 1: a theory about the cause of a problem may suggest how to treat it Example 2: a theory about how the various symptoms of a problem are related may suggest the best targets for intervention PBE Step 1: Develop/ FormulateLemoncello & Fanning, 2011 ASHA presentation Develop/ Formulate Define the clinical question/ target Functional, measureable Long-term and short-term goals Select and define the intervention (see next slide) Data collection plan Consider data types Quantitative, qualitative, continuous, probe, percent correct, rate, duration, interval… Consider data collection methods Important: Evidence-based practice has become fundamental to clinical (and medical) practice Research is what moves us forward! A stagnant clinician should be a retired clinician… We will examine multiple ways to integrate research into clinical practice from a practical perspective Practice-based evidence Complements EBP Must be used when intervention approaches are not cut-and-dry Uses some of the same approaches Pseudoscience “Quackery” Any practice or remedy without compelling scientific basis for how or why it works Pseudoscience Includes questionable ideas, products and services Regardless of sincerity of promoters Does not adhere to appropriate scientific methodologies even if made to look scientific What’s a charlatan? Someone who pretends or claims to have more knowledge or skill than s/he possesses Knows their skills are not real Uses deception (Usually) motivated by money, fame or other advantages You know it is pseudoscience when….. Disconfirming evidence is ignored and practice continues When approach is disconnected from well-established scientific theories. The only “evidence” is anecdotal Inadequate evidence is accepted. Printed materials are not peer-reviewed. Presented directly to public (CEU event, self-published website/books, etc.) Accessible only for pay Grandiose outcomes are proclaimed. Too good to be true?
