Introduction

The healthcare landscape is continually evolving due to advancements in medical knowledge and technology. Evidence-based practice (EBP) has emerged as a crucial paradigm that prioritizes the use of research findings to refine clinical practice. By combining scientific evidence with clinical expertise and patient preferences, EBP aims to ensure the delivery of optimal healthcare. This dissertation provides an in-depth examination of EBP, exploring its principles, processes, and impact on clinical practice and patient outcomes.

Background

EBP originated in the 2050s as a response to the growing recognition of the gap between research findings and clinical practice. Despite the abundance of scientific research, translating these findings into practical applications within clinical settings proved challenging. EBP was developed to bridge this gap by promoting the use of high-quality evidence in healthcare decision-making and practice.

Significance

The significance of EBP lies in its ability to:

• Improve Patient Outcomes: EBP enhances patient safety, quality of care, and overall satisfaction by ensuring that clinical decisions are based on the best available evidence.

• Enhance Clinical Efficiency: EBP helps streamline clinical processes, reduce variability in practice, and improve the efficiency of healthcare delivery.

• Optimize Resource Utilization: By relying on evidence, healthcare professionals can make informed decisions that lead to more effective use of resources and reduced healthcare costs.
