Single descriptive studies are categorized under which level of evidence?

Single descriptive studies are categorized as Level 6 evidence. This classification refers to studies that provide information about the characteristics or outcomes of a particular population or phenomenon without testing a hypothesis or manipulating any variables. These studies are essential for generating initial data about a topic or for describing a specific aspect of nursing or healthcare practice.

Single descriptive studies often involve observations and detailed reports that help to build a foundation for understanding a particular issue. They can include case studies, surveys, or qualitative research that explores the experiences of individuals. While they do not provide high-level evidence like randomized controlled trials (which fall under higher levels of evidence), they serve as a valuable starting point in research by identifying patterns, generating hypotheses, and informing future studies. This makes them an essential component of the evidence-based practice framework.
