Evidence-Based Practice in Healthcare: Principles and Process
This paper provides an overview of evidence-based practice (EBP) in healthcare, examining its core characteristics, the steps involved in its application, and the role of medical literature in guiding clinical decisions. The paper discusses how EBP integrates scientific evidence, patient preferences, and clinical expertise to support individualized care. It also outlines the four stages of literature development relevant to EBP, from initial investigation to government approval, and identifies key information sources—including MEDLINE, EMBASE, and the Cochrane Library—that clinicians and librarians rely upon to implement evidence-based approaches effectively.

What makes this paper effective
- The paper grounds its explanation of EBP in a concrete clinical example — a newborn misdiagnosed due to experience-only decision-making — which illustrates the real-world stakes of bypassing evidence-based methods.
- It moves logically from definition to process to literature stages to information sources, giving the reader a structured understanding of EBP from concept to implementation.
- Citations are integrated throughout to support each major claim, lending academic credibility to an otherwise introductory overview.
Key academic technique demonstrated
The paper demonstrates the use of an illustrative case example to support an abstract argument. Rather than relying solely on definitions, the author anchors the importance of EBP in a brief narrative about a misdiagnosed infant — a technique that makes abstract principles tangible and persuasive for a general academic audience.
Structure breakdown
The paper is organized into four thematic sections: an introduction defining EBP and its core characteristics; a discussion of the steps involved and a cautionary clinical case; an explanation of the four stages of EBP literature development; and a closing section on the information sources clinicians and librarians use. A reference list in APA-adjacent format concludes the paper.
Introduction to Evidence-Based Practice
Evidence-based practice (EBP) has become increasingly prominent across several disciplines in healthcare. One of its major characteristics is its reliance on scientific evidence, individual patient choices and needs, and clinical expertise. EBP is a healthcare approach in which professionals use the best available evidence to make decisions for individual patients. It builds, enhances, and values clinical knowledge, including expertise in pathophysiology and the mechanisms of disease.
Furthermore, EBP involves conscientious and complex decision-making that is based not only on available evidence but also on the patient's situation, preferences, and characteristics. It recognizes the individuality inherent in healthcare and accepts that practice is constantly changing, involving several probabilities and uncertainties. Ultimately, EBP represents the formalization of a process that has long been practiced by the most skilled clinicians (McKibbon, 1998).
Steps and Clinical Decision-Making in EBP
Effective evidence-based practice requires both energy and time. The first step is to form pertinent and well-defined questions that must be answered in order to satisfy the needs of the patient (Sackett et al., 1997; Sackett et al., 1991). The next step involves gathering the information needed to answer these questions, which may include laboratory tests found in textbooks but most commonly involves peer-reviewed journal research articles (Covell, Uman, & Manning, 1985). Critically assessing and reading this information for decision-making follows, and then making and evaluating that decision based on outcomes.
Many clinicians find it sufficient to rely on their own experience or that of their colleagues; however, this approach can have negative consequences. One illustrative case involved a four-day-old baby girl born with various birth defects. The family was told by the physician that she might be deaf and blind, and that she would likely experience difficulties with development, growth, and feeding. They were also informed that she would not be mentally fit and that, because the condition was rare, the severity was difficult to determine. This clinical decision-making was limited to the physician's personal experience alone and left the family deeply distressed about their daughter's health. In reality, the child later entered kindergarten and was developing and growing normally (McKibbon, 1998).
This case underscores the importance of integrating broader scientific evidence alongside clinical experience, rather than depending on anecdotal judgment alone.
