Quick review of evidence based practice Debates in evidence based practice Overview of evidence for continence Resources Ways forward
History
Critique of medical practice The Cochrane Collaboration Actually, we don’t really base all of the things we do on good scientific evidence Evidence shows that some things we have ‘always done’ can even cause harm.
Evidence-based medicine
The conscientious, explicit and judicious use of current best evidence in making the decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research. ( Sackett et al, 1996, p. 249-254)
Evidence-based practice
The systematic interconnecting of scientifically generated evidence with the tacit knowledge of the expert practitioner to achieve a change in a particular practice for the benefit of a well defined client / patient group. French, 1999, p. 74

Why should clinicians think about EBP?
Providing care based on research / evidence will enable us to: Keep up to date – accurate information Develop our body of knowledge Provide a basis for clinical judgments & practice guidelines Provide high quality, cost effective care Eliminate worst practice Remain accountable Validate and justify care, Lobby for resources
What is evidence?
How do you know what you know?
Types of information in the literature Texts, secondary sources Descriptions Theoretical literature Single research studies Reviews of the literature Systematic reviews Meta-analyses
Weighing the Evidence
Not all research is well designed, valid, generalisable The evidence must be appropriate to The question Practice issue Client group Not all evidence is equal

Critique of this Approach to Weighing Evidence
RCT – effectiveness Does not necessarily provide answers for Diagnosis, prognosis, harm Patient decision-making, health behaviours, daily-living management Economic costs Discounts other forms of evidence How and why Tightly controlled studies may not be widely generalisable Study results may not take account of patient context Judgments about when the evidence is relevant
JBI Applicability FAME Scale F easibility
evidence about the extent to which an activity or intervention is practical.
A ppropriateness
evidence about the extent to which an activity or intervention is Ethical or culturally apt.
M eaningfulness
evidence about the personal opinions, experiences, values, thoughts, beliefs or interpretations of clients and their families or significant others.
E ffectiveness
evidence about the effects of a specific intervention on specific outcomes.

Systematic reviews Summaries Abstracts Practice sheets Evidence-based clinical guidelines
A Systematic Review is:
“… a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research” (Cochrane, 2005).
How are they done?
A systematic review Has a focused clinical question, protocol Based on research evidence – not authority, opinion Focuses on a client group, intervention, risk factor Examines benefits, harm, cost effectiveness The search is exhaustive Examines rigour of research Includes consultations with clinicians Weighs levels of evidence
When should a systematic review be carried out?
The problem requires a response from health professionals There is a recurring practice problem To investigate a common therapeutic practice or approach To develop standards or protocols Recent research generates questions about practice

What information should I be keeping up with?
Usefulness = Relevance X Validity Work it takes to find out
J of Fam Pract 1994 38, 505-513
Relevance of Information
Is this research client/practice focused?
Will it change my practice / affect clinical decision making?
Are these findings applicable to my clients / practice?
Was the setting for this research similar to my clients’ setting / practice setting? Is the research valid?
Are the results significant?
What does experience and expertise contribute?
Assessment skills Judgment Efficiency and effectiveness More thoughtful, compassionate care An ability to apply the appropriate knowledge to the right situation
Knowledge that would contribute to improving continence practice:
Effectiveness of continence treatments, therapy and care Experience of and responses to incontinence, therapy, treatment, advertising, product use, etc.
Processes for providing continence care, purchasing, etc.
Inequities in continence care provision / service provision Socio-cultural impacts of incontinence, buying patterns, etc.
Issues generating conflicting perspectives
The Challenge for Continence Care
Basic research to generate new knowledge about continence treatment & care Get continence issues on the EBP agenda Undertake systematic reviews in relation to core practices in continence care Make this information accessible to practitioners Provide organisational support for EBP and research Fund research / access funding
Changes to Practice
Question practice decisions based on authority alone Reflect on practice Look for evidence as a basis for decision making Use clinical guidelines based on evidence that have been developed by others Ongoing review of clinical guidelines, based on evidence Evaluate the outcomes of practice Generate questions that need answering
Developing EBP Approaches
Develop and lobby for clinically-relevant questions for systematic reviews Learn how to apply the results of studies done by others Share knowledge / expertise with others eg. attend conferences Learn to read research articles and systematic reviews critically eg. Start a journal club Resources Use the library / databases Develop a library of CATS (critically appraised topics) Subscribe to the JBI, Cochrane Develop research skills / team up with someone who has research skills
Barriers to EBP
Attitudes
Most clinicians do not read research literature, use research findings (eg. Nagy, et al, 1992)
Resources
Access to libraries, journals, systematic reviews, research expertise, etc.
Support
Time, financial support to conduct research and disseminate findings Organisational culture / structure
Knowledge
Sources of Information
Different sources are required for different types of evidence Guidelines – professional organisations Systematic reviews - Evidence based practice centres National or local data - grey literature, organisational material

The Future
Clinically-focused research Clinicians developing and shaping their own practice area through research, publication Collaboration between clinicians and academics to develop knowledge to support evidence based practice eg. Research positions in health agencies More research into clinical practice undertaken by/in collaboration with clinicians Strategic planning for research activity in clinical practice Development of a library of evidence-based knowledge
Clinically-focused, rigorous research can be used to develop knowledge, enhance practice, and validate the value of practice in continence care.
The outcome of refining and applying knowledge better care is for people with incontinence

Effectiveness: RCT, cohort studies etc.
Appropriateness: meta-analysis / synthesis of interpretive research Feasibility: action research, critical approaches Basic research required to generate new knowledge Develop rigorous ways of evaluating the findings from non-RCT research
Questions and Critique of EBP in Continence Care
Don’t we do this now?
Could become a straight jacket for practice Could be used as a cost cutting measure What counts as evidence? Focuses on the measurable, values outcomes, not processes Limited research evidence in continence care Insufficient research skills We have to implement practices right now Where does experience and expertise fit?

Evidence obtained from a systematic review of all relevant randomised controlled (RCT) trials II Evidence obtained from at least one properly designed randomised controlled trial III.1 Evidence obtained from well-designed controlled trials without randomisation III.2 Evidence obtained from well-designed cohort or case-control analytic studies preferably from more than one centre or research group III.3 Evidence obtained from multiple time series with or without the intervention. Dramatic results in uncontrolled experiments IV Opinions of respected authorities, based on clinical experience, descriptive studies, or reports of expert committees
Key Questions 1. Evidence base A B C D A B Several Level I or II studies with low risk of bias one or two Level II studies with low risk of bias or SR/multiple Level III studies with low risk of bias C D 2. Consistency Level III studies with low risk of bias or Level I or II studies with moderate risk of bias Level IV studies or Level I to III studies with high risk of bias A B C D NA All studies consistent Most studies consistent and inconsistency can be explained Some inconsistency, reflecting genuine uncertainty around question Evidence is inconsistent Not applicable (one study only) 3. Clinical impact A Very large B C D Moderate Slight Restricted 4. Generalisability Evidence directly generalisable to target population Evidence directly generalisable to target population with some caveats Evidence not directly generalisable to the target population but could be sensibly applied Evidence not directly generalisable to target population and hard to judge whether it is sensible to apply 5. Applicability A B C D Other factors Evidence directly applicable to Australian healthcare context Evidence applicable to Australian healthcare context with few caveats Evidence probably applicable to Australian healthcare context with some caveats Evidence not applicable to Australian healthcare context (NHMRC 2008)
