Overview EBPP : The broader context 2 components Resources/Techniques… For finding the evidence For having the evidence find you For linking clinicians and researchers The future

Psychology introduces EBPP 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)
2005 2006
Best research available CD Clinical Expertise Patient characteristics, culture, preferences The framework of EBM 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.
ON-LINE EBP TUTORIAL SITES “evidence based nursing tutorial” (26) “evidence based social work tutorial” (4) “evidence based psychology tutorial” (0) “evidence based practice in psychology tutorial” (0) “evidence based medicine tutorial”(603) SEARCH TERM = “evidence based….tutorial” August 31, 2006
EBP is more than just the framework. • Specific resources have emerged to help practitioners “do” EBP. • These have been the major focus in other fields. • New to psychology.
Techniques / Resources for “doing” EBP • 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.
EBP Resources • For finding the evidence • For having the evidence find you • For linking clinicians and researchers

High Specificity WHAT WHERE HOW
High Specificity WHAT: Systematic review WHERE: Specialized databases HOW: Search strategies (controlled vocabulary)
Traditional reviews SECONDARY LITERATURE: papers that synthesize original studies PRIMARY LITERATURE
Traditional reviews SECONDARY LITERATURE: papers that synthesize original studies SYSTEMATIC REVIEWS PRIMARY LITERATURE
Systematic vs. Traditional Reviews • Focus is on a clear clinically relevant question. • End with a clinical bottom-line. • Specific, pre-determined method and format. • Research on research. • Search for all relevant studies. • Avoid bias • Goal is replication
Traditional reviews SECONDARY LITERATURE: papers that synthesize original studies SYSTEMATIC REVIEWS PRIMARY LITERATURE META-ANALYSES
Medical / Health Databases PSYCINFO MEDLINE Adapted from Shahram Yazdani, 2002
Cochrane / others Cochrane and other EBM databases are not linked to PsycINFO Overlap between Medline and Embase =30-70% EMBASE PSYCINFO MEDLINE Adapted from Shahram Yazdani, 2002
Clinicians need to “…know when their uncertainty stems from gaps in the evidence rather than gaps in their own knowledge.”
Postnatal depression QUESTIONS What are the effects of drug treatments for postnatal depression? What are the effects of non-drug treatments for postnatal depression? DRUG TREATMENTS Likely to be beneficial Selective serotonin reuptake inhibitor antidepressants (fluoxetine and paroxetine) Unknown effectiveness Antidepressants other than fluoxetine and paroxetine Hormones NON-DRUG TREATMENTS Likely to be beneficial Cognitive behavioural therapy (individual) Interpersonal psychotherapy Non-directive counselling Psychodynamic therapy Unknown effectiveness Cognitive behavioural therapy (group) Light therapy Mother–infant interaction coaching Psychoeducation with partner Telephone based peer support (mother to mother)
What: systematic review, other syntheses • Where: Cochrane, other specialized databases, EB on-line text books • How • Controlled vocabulary • SUMSEARCH
Controlled Vocabulary Librarians “tag” each article with labels based on the concepts in the article. These labels are standardized. • Medline: MeSH terms • PsycINFO: Thesaurus
Finding the evidence • The evidence can find you: Alerts
“To have more evidence-based practice, we need more practice-based evidence.”
CATs • Critically appraised topics: SHORT • Cat Maker • Cat Banks • Cat Crawler • Kittens • BETs
