Evidence based health care

isthe integration of individual clinical expertise

with

the best available external clinical evidence and

the values and expectations of the patient


9/31

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

learning

Involves exploring the relationship betweenclinical reasoning and research evidence

Involves practice


10/31

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 Do nothing and get out of date Depend solely on courses/conferences Choose the main professional journal(s) and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

Evidence Based Nursing PracticeKnowledge Standard

Each nurse possesses, through basic education and

continuing learning, knowledge relevant to her/hisprofessional practice

needs of complex clients Knowing where/how to access learning resources

when necessary

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


27/31

Evidence Pyramid

Important medical questions are typically studied

more than once, often by different research teams in

different locations. A meta-analysis combines resultsfrom different studies, hopefully averaging out anydifferences caused by random change or localvariation and getting at something close to the realtruth. In general a meta-analysis, if you can find one,

will be a better guide to practice than an individualarticle.
