Quick review of evidence based practice
  • Debates in evidence based practice
  • Overview of evidence for continence
  • Resources
  • Ways forward
history
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)

slide5
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
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
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
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

key questions
Key Questions
  • Evidence base
  • Consistency
  • Clinical impact

critique of this approach to weighing evidence
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
JBI Applicability FAME Scale

Feasibility

evidence about the extent to which an activity or intervention is practical.

Appropriateness

evidence about the extent to which an activity or intervention is Ethical or culturally apt.

Meaningfulness

evidence about the personal opinions, experiences, values, thoughts, beliefs or interpretations of clients and their families or significant others.

Effectiveness

evidence about the effects of a specific intervention on specific outcomes.

(JBI, 2008)

  • Systematic reviews
  • Summaries
  • Abstracts
  • Practice sheets
  • Evidence-based clinical guidelines
a systematic review is
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
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
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

  • Provide organisational support for EBP and research
  • Fund research / access funding
changes to practice
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
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

    • 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
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

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
slide42
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
