Determining the Credibility of Evidence and Resources in Evidence-Based Practice

Assessment 2 Instructions: Determining the Credibility of Evidence and Resources

Develop a 2-4 page scholarly paper in which you describe a quality or safety issue, or a chosen diagnosis, and then identify and analyze credible evidence that could be used as the basis for applying EBP to the issue.

The goal of using evidence-based research findings is to enhance safety and quality of patient care and ensure optimal outcomes are achieved. It is not uncommon to hear a nurse say, “why change it as we’ve always done it this way.” However, this is no longer acceptable in today’s practice environment. The profession of nursing has evolved, and the expectation is that the professional nurse has a scientific foundation to support the care that is provided. As the profession of nursing continues to evolve and engage in health care transformation, baccalaureate-prepared nurses are expanding taking on leadership roles that include incorporating EBPs. To be able to do this, the nurse needs to understand the criteria and makes a resource credible, as this is crucial when deciding if the research is valid and reliable for implementation into health care settings. The nurse will need to incorporate the use of evidence-based practice models. EBP models are designed to assist the nurse in developing a plan to gather evidence to answer a practice problem or question. It is a systematic approach to direct the user to incorporate scholarly findings into current practice. These EBP models lead the nurse through the decision-making process of evaluating the literature to determine the best practice evidence for the practice issue or question.

It would be an excellent choice to complete the Vila Health Determining the Credibility of Evidence activity prior to developing the report. The activity is a media simulation that offers an opportunity to review a scenario and work on determining the credibility of presented evidence. These skills will be necessary to complete Assessment 2 successfully. This media simulation is one potential source of context on which to base your assessment submission. This will take just a few minutes of your time and is not graded.

Professional Context
As a baccalaureate-prepared nurse, you will be responsible for locating and identifying credible and scholarly resources to incorporate the best available evidence for the purposes of enhancing clinical reasoning and judgement skills. When reliable and relevant evidence-based findings are utilized, patients, health care systems, and nursing practice outcomes are positively impacted.

For this assessment, you may choose from the following options as the context for the quality or safety issue or chosen diagnosis/health issue for researching and completing this assessment:

The specific diagnosis/health issue you identified in your previous assessment.

The specific diagnosis/health issue you identified in your previous assessment.

The simulation Vila Health: Determining the Credibility of Evidence. A personal practice experience in which a sentinel event occurred.


The purpose of this analysis is to better understand what constitutes credibility of journal articles as well as websites. The role of the baccalaureate-prepared nurse in incorporating evidence-based research continues to growth in clinical practice. As quality improvement (QI) measures to reduce safety risks continue to be emphasized, the need for evidence-based models and evidence-based templates is growing. This type of systematic approach to incorporating evidence-based findings allows nurses to make clinical and operational decisions based upon the best available evidence. When the most up-to-date evidence-based findings are utilized, patient-centered care improves outcomes and enhances the patient experience.

Below is a quick review table of several well-known Evidence-Based Practice Models used to guide exploration:

Evidence-Based Practice Models

Determining the Credibility of Evidence and Resources in Evidence-Based Practice

In the realm of healthcare, evidence-based practice (EBP) plays a crucial role in enhancing patient care quality and safety. As nursing evolves and engages in healthcare transformation, it is expected that baccalaureate-prepared nurses possess a scientific foundation to support their provided care. To meet these expectations, nurses need to understand the criteria for determining the credibility of evidence-based research and resources. By incorporating the use of EBP models, nurses can effectively gather and evaluate evidence, thus ensuring the implementation of valid and reliable research in healthcare settings. This paper aims to explore the criteria for evaluating the credibility of journal articles and websites, analyze the relevance and credibility of evidence within a specific context, and emphasize the importance of incorporating credible evidence into an EBP model.

Criteria for Determining Credibility
When evaluating the credibility of journal articles and websites, several criteria should be considered. Firstly, the source’s authorship and affiliation play a significant role in determining credibility. It is important to identify whether the author possesses the necessary expertise and qualifications in the field. Peer-reviewed journal articles, where experts in the field have critically evaluated the research, are considered more credible than non-peer-reviewed sources. Furthermore, the reputation and prestige of the publishing journal or website also contribute to its credibility. Journals with rigorous editorial standards and a reputable publishing history are more likely to publish reliable research.

Another criterion to consider is the accuracy and reliability of the information presented. Credible sources should provide accurate data, supported by appropriate references and citations. It is important to critically evaluate the methodology employed in the research, ensuring it is sound and appropriate for the research question. Moreover, transparent reporting of the findings, including limitations and potential biases, enhances the credibility of the source.

The currency of the information is another crucial aspect of credibility. In rapidly evolving fields like healthcare, it is important to rely on recent and up-to-date research. Outdated information may not accurately reflect current practices, interventions, or treatments. It is recommended to prioritize sources published within the last five years, as they are more likely to incorporate the latest advancements and discoveries.

Analyzing Credibility and Relevance
Within the chosen context of a quality or safety issue or a chosen diagnosis, it is imperative to analyze the credibility and relevance of the evidence and resources. For instance, if the selected context is the Vila Health scenario, the initial identification of resources should address the presented issue. On the other hand, if the focus is on providing evidence-based care for a specific diagnosis or healthcare issue, databases identified in the first assessment should be utilized. By considering the criteria mentioned earlier, nurses can assess the credibility and relevance of the identified evidence.

Credibility can be determined by critically examining the author’s credentials, the publication source, and the methodological rigor of the research. Relevance, on the other hand, is assessed by evaluating how well the evidence aligns with the specific context and addresses the identified issue. The evidence should directly relate to the quality or safety issue or the chosen diagnosis, providing insights and potential solutions to improve patient outcomes.

Importance of Incorporating Credible Evidence into EBP Models
The selection of an appropriate evidence-based practice model is crucial for addressing a quality or safety issue or a chosen diagnosis effectively. Various models, such as the Iowa Model of Evidence-Based Practice, Stetler Model, Ottawa Model, PARiHS Model, ACE Star Model, ARCC Model, John Hopkins Model, and KTA Model, provide frameworks for implementing EBP. When incorporating credible evidence into these models, nurses ensure that their practice is grounded in the best available evidence.

By using reliable and relevant evidence, nurses enhance their clinical reasoning and judgment skills, leading to improved patient-centered care and better outcomes. Credible evidence helps nurses make informed decisions and develop care plans that align with current best practices. This integration of evidence also promotes a culture of continuous improvement, where healthcare professionals strive to enhance their knowledge and adapt their practices based on new evidence.

In conclusion, determining the credibility of evidence and resources is essential for implementing evidence-based practice in healthcare. By considering criteria such as authorship, accuracy, reliability, and currency, nurses can assess the credibility of journal articles and websites. Analyzing the credibility and relevance of evidence within the chosen context further ensures the appropriateness of the research for addressing the identified issue. Incorporating credible evidence into an evidence-based practice model is vital as it enhances clinical decision-making, promotes quality improvement, and leads to better patient outcomes. Baccalaureate-prepared nurses should strive to utilize evidence-based research to enhance their clinical practice, ensuring that the care provided is supported by the best available evidence.
