The findings of this study reveal complex interplays between interprofessional collaboration, hierarchical structures, and nurse-led initiatives in implementing EBPs within acute care settings. Key themes such as knowledge sharing, barriers due to professional silos, and the role of CPD emerged, all of which reinforce the necessity of a collaborative and empowering healthcare environment for EBP. These findings align with previous research while also highlighting unique challenges and opportunities within the study sites.
The findings indicate that interprofessional collaboration significantly facilitates EBP adoption, a view supported by Reeves et al.., (8), who argue that interprofessional teamwork enhances knowledge exchange, ultimately leading to improved patient outcomes. Regular interdisciplinary meetings allowed nurses and physicians to share insights and align protocols, illustrating how formalised structures can improve communication, a point echoed by Grimshaw et al., (11). However, the lack of formal collaboration structures slowed EBP adoption, suggesting that the absence of structured interactions may undermine the speed and efficacy of implementing evidence-based changes. Sullivan et al., (10) similarly argue that professional silos and the absence of regular interdisciplinary meetings can hinder EBP adoption, creating inefficiencies in decision-making. This comparative insight supports the notion that effective collaboration is contingent on formal structures that facilitate dialogue across professions, yet the findings also suggest that even informal collaboration, as observed at Site 2, can initiate positive change, albeit more slowly.
Both study sites reported significant barriers due to professional silos, with nurses often excluded from decision-making processes. This aligns with the work of Dunn et al., (26) and Ominyi et al., (2), who found that hierarchical structures in healthcare often subordinate nursing perspectives to medical authority, limiting nurses' capacity to advocate for EBPs effectively. The hierarchical barriers evident in this study exemplify how power dynamics in healthcare can stifle nurses' evidence-based suggestions, even when such recommendations have the potential to improve patient outcomes. Brown et al., (15) also identified these silos as sources of frustration, as healthcare workers experienced delays in practice change implementation due to a lack of engagement and feedback from other professional groups. These barriers suggest that healthcare organisations must address hierarchical dynamics to facilitate a more inclusive decision-making process, enabling nurses to participate fully and contribute their insights into patient care practices.
Despite the hierarchical constraints, nurses at both sites demonstrated a proactive approach to EBP, using their clinical expertise to introduce evidence-based changes in infection control and wound care. This finding aligns with Harvey et al., (1), who highlight the critical role of nurses as change agents in direct patient care. Moreover, Gerrish et al., (6) found that empowering nurses to act independently often led to improved patient safety and care outcomes. Nurses in this study leveraged informal knowledge-sharing networks to drive improvements in practice, particularly when formal approval from physicians was not immediate. This self-driven initiative underscores the potential of nurse-led interventions in advancing EBP, even within restrictive organisational structures.
The findings emphasise the importance of CPD in empowering nurses to implement EBPs confidently. Study findings reveal that structured CPD opportunities can boost nurses’ confidence in suggesting evidence-based changes, a result consistent with McCormack et al. (16), who argue that CPD enhances practitioners' capacity to challenge outdated practices. However, Site 2’s reliance on self-driven educational pursuits illustrates the limitations of under-resourced environments, where formal CPD support is sparse. The disparity between the two sites reinforces Melnyk and Fineout-Overholt’s (4) argument that healthcare organisations must invest in continuous, structured professional development to support sustained EBP integration. Without organisational support for CPD, nurses may struggle to access the resources and training necessary to lead evidence-based improvements effectively.
The study highlights the importance of interprofessional collaboration and nurse-led initiatives in effective EBP implementation. Formal interdisciplinary meetings enhance communication, decision-making, and reduce silos, thereby improving patient care. Additionally, investing in structured CPD for nurses builds confidence and strengthens their advocacy for evidence-based changes. Healthcare organisations should prioritise these areas to support sustained EBP integration and optimise healthcare delivery. For future research, examining ways to minimise hierarchical barriers and exploring the long-term impact of collaboration structures on EBP are essential. Research on structured CPD programmes, particularly in resource-limited settings, and identifying best practices in nurse-led EBP initiatives could further support patient care improvements.
Strengths and limitation
This study’s strengths lie in its use of a collective qualitative case study design, providing an in-depth exploration of knowledge implementation across diverse acute care settings. Through triangulation of data from interviews, observations, and document analysis, the study ensures a comprehensive understanding of facilitators and barriers in EBP adoption. However, the study has limitations; the perspectives primarily represent staff nurses, nurse managers, and physicians, potentially overlooking insights from other key stakeholders, such as patients and policymakers, which could further enrich the understanding of interdisciplinary challenges in knowledge implementation.
