The importance of evidence

What is Evidence-Based Practice? o o An approach to clinical practice A way to keep current with new developments N. Mac. Intyre, 2005

What is Evidence-Based Practice? o … 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 Centre for Evidence-Based Medicine

What is Evidence-Based Practice? o … 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 Health Information Research Unit, Mc. Master, 2002

What is Evidence-Based Practice? o … 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 J. A. Muir Gray, 1997

What is Evidence-Based Practice? Evidence based health care is the integration of individual clinical expertise with the best available external clinical evidence and the values and expectations of the patient D. Sackett et al, 1996

Evidence-Based Practice o Involves life-long, self-directed, problem-based learning o Involves exploring the relationship between clinical reasoning and research evidence o Involves practice N. Mac. Intyre, 2005

Keeping Up? o o Do nothing … and get out of date Depend solely on courses/conferences Choose the main professional journal(s) and read them cover to cover every month Learn how to find appraise the evidence to answer questions that come from clinical practice N. Mac. Intyre, 2005

Evidence Based Nursing Practice Knowledge Standard o Each nurse possesses, through basic education and continuing learning, knowledge relevant to her/his professional practice Ontario College of Nurses, 2002

Evidence Based Nursing Practice Knowledge Standard Indicators o o o Providing a theoretical and/or evidence-based rationale for all decisions Understanding the knowledge required to meet the needs of complex clients Knowing where/how to access learning resources when necessary Ontario College of Nurses, 2002

Evidence Based Nursing Practice Knowledge Standard Indicators o Seeking and reviewing research in nursing, health sciences and related disciplines o Using research to inform practice/professional service Ontario College of Nurses, 2002

Evidence Based Nursing Practice Knowledge Application Standard o Each nurse continually improves the application of professional knowledge Ontario College of Nurses, 2002

Evidence Based Nursing Practice Knowledge Application Standard Indicators o o o Ensuring practice is based in theory and evidence and meets all relevant standards/guidelines Assessing/describing the client situation using a theory, framework or evidence-based tool Managing multiple nursing interventions simultaneously Ontario College of Nurses, 2002

Evidence Based Nursing Practice Knowledge Application Standard Indicators o Evaluating/describing the outcome of specific interventions and modifying the plan/approach o Integrating research findings into professional service and practice Ontario College of Nurses, 2002

Five Steps of Evidence-Based Practice o Define the Question n Identify Question ~ Search and Screen Literature ~ Refine Question o Collect the Evidence o Critically Appraise the Evidence for Validity and Relevance N. Mc. Kibbon, 1999

Five Steps of Evidence-Based Practice o Integrate the Evidence and Patient Factors n o Make & Carry Out the Decision Evaluate the Process n Results ~ Self-reflection N. Mc. Kibbon, 1999

PICO o A clinical question should incorporate at least three elements o Patient n n o Age, sex, ethnicity, etc. Condition, diseases, general health status Intervention n Education, diagnostics, treatment plan, self-care, etc.

PICO o Comparison Intervention n o Placebo, etc. Outcome n Expected and actual effects on patient

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

PICO o PATIENT n n n o (Adult) coronary heart patients Smokers Discharged from hospital INTERVENTION n Nurse led tobacco cessation programmes

PICO o COMPARISON n (Non-nurse led tobacco cessation programmes o n o Self-administered, non-nurse administered, etc. ) No comparison OUTCOME n Lower rates of tobacco use among Patient group

PICO o Not all questions are of a clinical nature o Intervention can be interpreted very broadly

Evidence Pyramid SUNY Downstate Medical Center, 2003

Evidence Pyramid o “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. ” SUNY Downstate Medical Center, 2003
