Barriers and Facilitators in Implementing Clinical Practice Guidelines Among Nurses in Emergency Departments and Critical Care Units: A Systematic Review.

aimThis systematic review explored the barriers and facilitators to the implementation of clinical practice guidelines (CPGs) among nurses in emergency departments (EDs) and critical care units (CCUs).

designSystematic review.

methodA systematic review was performed using both qualitative and quantitative studies from five databases (CINAHL, Web of Science, Embase, Scopus and PubMed). The literature search was conducted in May 2024. The PRISMA framework was used to guide the review process. Findings were subject to a narrative, thematic analysis and critical appraisal.

resultsEighteen studies were identified that met the inclusion criteria, yielding three themes related to barriers and facilitators of guideline implementation: individual-level, guideline-level and organisational-level. Key barriers included lack of awareness of guidelines, lack of knowledge and skills, attitudes towards guidelines, resource limitations, lack of perceived support, complexity of guidelines and lack of training. Facilitators to guideline use included colleague support, adequate training, effective leadership and refinement of guidelines to ensure relevance, local adaptation and user-friendly content. DISCUSSION: Numerous barriers to nurse implementation of CPGs exist in ED and CCU settings, reflecting a complex interplay of individual, CPG-related and organisational factors. To facilitate CPG implementation, it is important for staff to be educated and trained in their use, supported to implement (including resource allocation) and that CPGs are designed to be easily implemented in practice.

conclusionThis systematic review highlights risk factors for poor CPG implementation and highlights the importance of addressing awareness, knowledge, resources and support for CPG use through targeted training, leadership and CPG design. RELEVANCE TO CLINICAL PRACTICE: An analysis of barriers and facilitators to CPG implementation among nurses in ED and CCU settings provides an important opportunity to address a gap in the literature, facilitating the development of strategies to promote CPG use and enhance care quality among nurses in these specific contexts.
