What is the primary purpose of a literature review in nursing research?

The primary purpose of a literature review in nursing research is to present a strong knowledge base for the research study. This involves synthesizing existing research findings, theories, and methodologies related to the study topic, thereby establishing a foundation for the new research being undertaken.

By effectively summarizing and analyzing the current body of knowledge, the literature review helps to inform the research questions and hypotheses, guiding the design and methodology of the study. It emphasizes the relevance of the new study in the context of what is already known and highlights the significance of the research to advance nursing practice and contribute to evidence-based care.

While identifying gaps in research, critiquing previous studies, and gathering qualitative data can also play roles in literature reviews, they serve more specific functions within the broader aim of justifying the research. The central goal remains to develop a comprehensive understanding that supports the rationale behind conducting the new study.
