Evidence-Based Practice Overview

Definition by Professor David Sackett: A conscientious effort to find the best research evidence to help health professionals make informed decisions for patient care.
Originated in evidence-based medicine but has expanded to all health professions and services under the term 'evidence-based practice'.

Key Elements of Evidence-Based Practice

Emphasis on integrating multiple information sources: patient information, clinical settings, and crucially, research evidence.
Distinction made by Sackett: 'evidence' specifically refers to data derived from research studies, not just general clinical knowledge.

Process of Evidence-Based Practice

Involves framing a clinical information need into a question.
Search for relevant research evidence.
Assess the quality of gathered evidence.
Determine the application of the evidence to address the clinical question.

Importance of Research Evidence

Enhances clinical decision-making by providing testing and data rather than solely relying on theoretical or anecdotal knowledge.
Differentiation from traditional science-based information, which often relies on mechanisms of illness rather than empirical evidence.

Misleading Mechanisms of Illness Approach

Prior recommendations based on mechanisms can result in incorrect clinical practices:
- Infant sleep position: Earlier recommendation to place babies on their fronts contradicted by research correlating backsleep with reduced SIDS rates.
- Post-heart attack care: Bed rest was thought necessary; studies showed it actually increases the risk of thromboembolism.
- Wound care after skin cancer removal: Rationale was to prevent infection; research demonstrated open wounds did not increase infection rates.

Conclusion

Evidence-based practice serves as a robust framework to improve clinical decision-making by combining patient-centered data with validated research findings.
