A charge nurse is discussing evidence-based practice (EBP) and the hierarchy of evidence with a newly licensed nurse.
Which of the following examples should the nurse provide when discussing Level I evidence?

Choice A rationale:

Systematic reviews are considered Level I evidence in the hierarchy of evidence in evidence-based practice (EBP). Systematic reviews involve the rigorous and comprehensive synthesis of multiple research studies on a specific topic. This approach minimizes bias and provides the highest level of evidence for making clinical decisions. Systematic reviews typically follow a structured methodology and offer a critical analysis of the existing literature, making them a strong foundation for EBP.

Choice B rationale:

Credible websites are not considered Level I evidence. While some websites may contain reliable information, they vary in quality, and the credibility of the source must be carefully assessed. Relying solely on websites is not the most robust approach in EBP, as it lacks the rigorous systematic review and critical appraisal process of Level I evidence.

Choice C rationale:

Expert opinions are not considered Level I evidence. While expert opinions can be valuable, they are often based on individual experiences and interpretations rather than systematic research. Expert opinions are generally considered lower in the hierarchy of evidence compared to systematic reviews and other forms of research evidence.

Choice D rationale:

Qualitative studies are not considered Level I evidence. Qualitative studies provide valuable insights into the experiences, perceptions, and meanings associated with a particular phenomenon. However, they are typically ranked lower in the hierarchy of evidence compared to systematic reviews and quantitative research studies. Qualitative studies are more appropriate for addressing research questions related to subjective experiences and understanding the "why" and "how" of a phenomenon.

Choice A rationale:

In this scenario, the nurse is gathering evidence-based practice on catheter-associated urinary tract infections (CAUTI). By collecting evidence-based information and research on this topic, the nurse is acting in the role of a researcher. Research in healthcare is essential to stay current with best practices, guidelines, and recommendations, and it helps inform clinical decision-making.

Choice B rationale:

A nurse manager is responsible for overseeing nursing staff, unit operations, and ensuring that the unit operates efficiently and safely. While a nurse manager may use evidence-based information to guide decisions, the primary role described in this scenario is that of a researcher, as the nurse is focused on gathering evidence-based practice on a specific topic.

Choice C rationale:

An educator's primary role is to teach and educate others, such as patients, families, or fellow healthcare professionals. While education often involves the use of evidence-based information, in this scenario, the nurse is primarily focused on gathering evidence rather than directly educating others.

Choice D rationale:

A case manager is responsible for coordinating and managing a patient's care, often involving multiple aspects of healthcare and social services. While case managers may use evidence-based information in their decision-making, the primary role described in this scenario is that of a researcher, as the nurse is focused on gathering evidence-based practice related to CAUTI, not managing a specific patient's case.
