Nurses' Perceptions on the Role of Advanced Psychiatric Nurses in Mental Healthcare: An Integrative Review.

Background/Objectives: Advanced psychiatric nurses' clinical skills and expertise are increasingly challenging registered nurses in mental health. Understanding registered nurses' perceptions of the role of advanced psychiatric nurses is vital for improving mental healthcare delivery and fostering collaboration for effective patient outcomes. This integrative review aims to explore how registered nurses perceive the role of advanced psychiatric nurses in mental healthcare. Methods: An integrative review methodology was used to synthesize the existing literature following PRISMA guidelines. Both qualitative and quantitative studies provided a comprehensive understanding of the registered nurses' perceptions regarding the role of advanced psychiatric nurses in mental health nursing. Results: Several key themes emerged from studies included in this review, including recognition of expertise, role ambiguity and boundaries, and the need for structured education and training. Conclusions: This review highlights the need to clarify roles and how communication is essential for improving collaboration, team cohesion, and patient outcomes while promoting interprofessional education to optimize mental healthcare, in addition to bridging the knowledge gap or the discrepancy between registered nurses and advanced psychiatric nurses. What registered nurses know and what they need to know to perform tasks will improve the quality of mental healthcare and optimize services for individuals with mental health needs.
