Centre for Evidence-Based Medicine

What is Evidence-Based Practice?

… a methodological approach to clinical practice where evidence is used to inform decision-making about making a diagnosis (or interpreting a diagnostic test), selecting an intervention, or evaluating prognostic indicators

Health Information Research Unit, McMaster, 2002

What is Evidence-Based Practice?

… an approach to health care practice in which the clinician is aware of the evidence that bears on her clinical practice, and the strength of that evidence

J. A. Muir Gray, 1997

What is Evidence-Based Practice?

… an approach to decision making in which the clinician uses the best evidence available, in consultation with patient, to decide upon the option which suits that patient best

D. Sackett et al, 1996

What is Evidence-Based Practice?

Evidence based health care is

the integration of individual clinical expertisewith

the best available external clinical evidence and the values and expectations of the patient

N. MacIntyre, 2005

Evidence-Based Practice Involves life-long, self-directed, problem-

based learning

Involves exploring the relationship between clinical reasoning and research evidence

Involves practice

N. MacIntyre, 2005

Keeping Up? Do nothing … and get out of date Depend solely on courses/conferences Choose the main professional journal(s) and

read them cover to cover every month

Learn how to find and appraise the evidence to answer questions that come from clinical practice

The cognitive continuum.

N. McKibbon, 1999

Five Steps of Evidence-Based Practice

Define the Question Identify Question ~ Search and Screen Literature

~ Refine Question

Collect the Evidence

Critically Appraise the Evidence for Validity and Relevance

N. McKibbon, 1999

Five Steps of Evidence-Based Practice

Integrate the Evidence and Patient Factors Make & Carry Out the Decision

Evaluate the Process Results ~ Self-reflection

PICO A clinical question should incorporate at least

three elements

Patient Age, sex, ethnicity, etc. Condition, diseases, general health status

Intervention Education, diagnostics, treatment plan, self-care,

etc.

PICO

Comparison Intervention Placebo, etc.

Outcome Expected and actual effects on patient

PICO

Do nurse led tobacco cessation interventions result in decreased smoking rates after hospital admission for coronary heart disease?

PICO

PATIENT (Adult) coronary heart patients Smokers Discharged from hospital

INTERVENTION Nurse led tobacco cessation programmes

PICO

COMPARISON (Non-nurse led tobacco cessation programmes

Self-administered, non-nurse administered, etc.) No comparison

OUTCOME Lower rates of tobacco use among Patient group

PICO

Not all questions are of a clinical nature

Intervention can be interpreted very broadly

Evidence Pyramid

SUNY Downstate Medical Center, 2003

Evidence Pyramid

“Important medical questions are typically studied more than once, often by different research teams in different locations. A meta-analysis combines results from different studies, hopefully averaging out any differences caused by random change or local variation and getting at something close to the real truth. In general a meta-analysis, if you can find one, will be a better guide to practice than an individual article.”
