A literature review is crucial in nursing for several reasons: - Identifying Gaps: It helps identify gaps in current research, thereby guiding future studies. - Informing Practice: It provides evidence-based insights that can be used to improve clinical practice and patient care. - Supporting Education: It serves as an educational tool for nursing students and professionals by summarizing the state of knowledge on a given topic. - Guiding Policy: It informs policy-makers by synthesizing evidence that can be used to develop or modify healthcare policies.
