Aortic Regurgitation I: Introduction

1.6K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

    Summary

    Implementing evidence-based practices in perioperative nursing requires a systematic approach to evaluating scientific and non-research evidence. This process ensures that practice changes are informed by the best available information for optimal patient care.

    Area of Science:

    • Nursing Science
    • Evidence-Based Practice

    Background:

    • Nurses in perioperative settings must implement evidence-based practices (EBP).
    • EBP begins with identifying a clinical question or practice problem.
    • Literature searches and appraisal are crucial for assessing evidence.

    Purpose of the Study:

    • To describe the process of developing evidence-based recommendations for perioperative nursing practice.
    • To outline the methods used for appraising both research and non-research evidence.
    • To introduce a new evidence rating model for perioperative practice recommendations.

    Main Methods:

    • Systematic literature reviews conducted with medical librarians.
    • Independent appraisal of literature using AORN Research Appraisal Tool and AORN Non-Research Appraisal Tool.
    • Development of a new evidence rating model for research and non-research evidence.

    Main Results:

    • AORN recommended practices are synthesized from a systematic review of literature.
    • Literature is appraised for quality and strength by at least two independent appraisers.
    • A new evidence rating model has been implemented to evaluate supporting evidence.

    Conclusions:

    • The process ensures that perioperative practice recommendations are based on rigorously appraised evidence.
    • The new evidence rating model supports the evaluation of diverse evidence types.
    • This systematic approach enhances the implementation of evidence-based practices in perioperative nursing.
