We are at a defining moment for nursing and for health systems worldwide. The science of evidence-based practice has advanced at an extraordinary pace, producing a robust and ever-expanding body of knowledge to guide clinical decision-making, improve patient outcomes, and strengthen health system performance. Yet, despite these advances, a persistent and deeply consequential gap remains between what we know and what we consistently do in practice. This “know–do” gap continues to challenge the nursing profession and the broader healthcare community, limiting our collective ability to deliver optimal, equitable, and sustainable care [1].

This gap is no longer simply a matter of dissemination or awareness. It reflects deeper structural, cultural, and operational challenges that require urgent and coordinated attention. Bridging this divide is not only a technical priority – it is a systems imperative, a leadership responsibility, and a societal obligation. Patients, families, and communities depend on our ability to ensure that the best available evidence informs every aspect of care.

This special issue of the International Journal of Nursing Sciences, under the theme “Bridging the Gap: From Evidence-Based Guidelines to Clinical Excellence in Nursing,” is both timely and necessary. It brings together a diverse and international body of work that examines how evidence-based practice can be operationalized, adapted, implemented, and sustained across complex and evolving healthcare environments. Collectively, these contributions advance a critical conversation – one that shifts the focus from generating evidence to ensuring its meaningful and consistent application in practice.

At its core, this issue challenges us to rethink how we define success in nursing science. For decades, the emphasis has been placed on the development and validation of evidence [2,3]. While this remains essential, it is no longer sufficient [4]. The true measure of our progress lies in our ability to translate that evidence into improved outcomes at the bedside, homeside, streetside, within diverse communities, and across entire health systems. Implementation, therefore, is not a secondary consideration – it is the new frontier of nursing science [5].

The contributions in this issue make it abundantly clear that implementation is complex, dynamic, and deeply context-dependent. It cannot be reduced to a single intervention or linear process. Rather, it requires a comprehensive and integrated approach that considers the interplay between individuals, teams, organizations, and broader policy environments. Implementation science provides the conceptual and methodological tools to navigate this complexity, offering frameworks that help us understand not only what works, but how, why, and under what conditions [6].

A recurring theme across the studies presented in this issue is the critical role of structured implementation models in enabling system-level change. Initiatives grounded in best practice guideline implementation demonstrate that when evidence is supported by intentional design, strong leadership, and robust infrastructure, it can be embedded into routine practice in ways that are both scalable and sustainable. These models highlight the importance of governance structures, standardized indicators, continuous monitoring, and interprofessional collaboration in achieving meaningful and measurable outcomes [7].

However, these successes also underscore an important truth: evidence does not implement itself. The presence of guidelines, no matter how rigorous, does not guarantee their uptake. Without deliberate strategies, alignment of priorities, and ongoing support, even the strongest evidence can fail to influence practice [8]. This recognition calls for a shift in mindset – from viewing implementation as an afterthought to positioning it as a central component of healthcare design and delivery.

Context emerges as one of the most powerful determinants of implementation success. The studies in this issue span multiple countries, healthcare systems, and cultural settings, offering valuable insights into how evidence-based guidelines are adapted and applied in diverse environments. These contributions demonstrate that context is not an obstacle to be overcome, but a critical factor to be understood and leveraged.

Organizational culture, leadership engagement, resource availability, and interprofessional dynamics all shape how evidence is interpreted and enacted. In some settings, resource constraints may limit the feasibility of certain interventions, requiring creative and adaptive approaches. In others, deeply ingrained practices or hierarchical structures may influence the willingness of practitioners to adopt new ways of working. Effective implementation, therefore, requires both fidelity to evidence and flexibility, responsiveness, and cultural competence.

Importantly, this issue highlights the value of global perspectives in advancing evidence-based nursing practice. Cross-cultural adaptations of guidelines, experiences from resource-limited settings, and comparative analyses of health systems provide a richer and more nuanced understanding of implementation. They remind us that while the principles of evidence-based practice are universal, their application must be tailored to local realities. In doing so, we can move towards a more inclusive and equitable approach to healthcare improvement [9].

Another central theme is the importance of education and capacity building in bridging the gap between evidence and practice. Preparing nurses to engage with evidence is not a one-time endeavor, but a continuous process that spans undergraduate education, professional development, and lifelong learning. The studies in this issue present innovative educational models that integrate evidence-based thinking into curricula, promote critical appraisal skills, and foster the ability to translate knowledge into practice.

Competency-based approaches, systems-informed education models, and practice-integrated learning environments all contribute to narrowing the longstanding theory–practice gap. These models emphasize not only knowledge acquisition, but also the development of practical skills, clinical reasoning, and professional confidence. They recognize that the ability to implement evidence is as important as the ability to understand it.

Beyond formal education, the role of mentorship and leadership is particularly compelling. Mentorship serves as a powerful mechanism for supporting nurses in navigating the complexities of implementation. Through mentorship, experienced practitioners can provide guidance, facilitate contextual translation of evidence, and build confidence among their peers. This relational approach to knowledge transfer is essential for embedding evidence into everyday practice.

Leadership, at all levels, is equally critical. This includes executive and managerial leadership; clinical, education, and research leadership; and policy leadership – all of which play a decisive role in closing the theory–practice–outcome chasm. Educating new professionals in evidence-based practice, grounded in real-world contexts, equips them to leverage evidence to improve health for all. Executives and managers complement the roles of clinicians: the former set governing priorities and allocate resources, while the latter exercise clinical leadership at the point of care – influencing decision-making, modeling best practices, and supporting peers in applying evidence in real time. Researchers, embedded within complex and diverse work environments, uncover both hidden successes and critical gaps.

Together, these leaders shape organizational culture, align priorities, and create environments that enable effective implementation. Nurses in policy-making roles add their leadership to strengthen collective efforts by fostering shared purpose, encouraging innovation, and ensuring accountability. They champion nursing’s role in continuous improvement, challenging existing practices when they are not aligned with evidence.

Added to these human and organizational factors are technological innovations that are rapidly reshaping the landscape of healthcare delivery and implementation. Among these, artificial intelligence (AI) holds particular significance. AI-enabled tools – including predictive analytics, clinical decision support systems, and natural language processing – can support real-time, context-sensitive decision-making at the point of care, making evidence more accessible and actionable while enabling continuous monitoring of outcomes and practice patterns. Advanced analytics can also strengthen feedback loops between evidence generation, implementation, and evaluation, positioning digital intelligence as a critical bridge between knowledge and action in increasingly complex health systems.

At the same time, these advances introduce significant challenges that must be addressed deliberately. The quality, completeness, and representativeness of data remain central concerns, as biased or incomplete datasets risk reinforcing existing inequities and producing suboptimal or unsafe recommendations. The integration of AI into clinical workflows requires careful design to avoid adding burden or disrupting care processes. Ethical considerations – including transparency, accountability, privacy, and appropriate governance – are essential to maintaining public trust and professional integrity. Importantly, the growing reliance on digital tools must not diminish the relational, ethical, and human dimensions of nursing practice. Rather, digital intelligence should be positioned as a complement to, not a substitute for, professional judgment, compassion, communication, and person-centered care.

Ultimately, bridging the gap between evidence-based guidelines and clinical excellence requires a systems approach. It demands alignment across multiple domains – education, governance and management, human resources, clinical practice, research, and policy. It requires sustained investment in infrastructure, including data systems, training programs, and implementation support mechanisms. It also demands sustained investment in the expert professionals who provide care, recognizing their knowledge, judgment, and central role in translating evidence into practice. It also calls for policies that prioritize evidence-based practice and create incentives for its adoption and sustainability.

Equally important is the need for collaboration. No single individual, organization, or discipline can address this challenge alone. Interprofessional collaboration is essential for ensuring that evidence is integrated across the continuum of care. Partnerships between academia and practice settings can facilitate the co-creation of knowledge and support the translation of research into real-world applications. Engagement with policymakers can help to align regulatory and funding frameworks with the goals of evidence-based practice.

The contributions in this special issue provide both inspiration and direction. They demonstrate that progress is possible, even in the face of complexity and constraint. They offer practical strategies, conceptual advancements, and empirical evidence that can inform future efforts. At the same time, they highlight the work that remains to be done.

As we look to the future, we must embrace a new vision for evidence-based nursing practice – one that is dynamic, integrated, and action-oriented. This vision recognizes that evidence is not static, but evolves over time. It acknowledges that implementation is not a one-time event, but an ongoing process of learning, adaptation, and improvement. It places nurses at the center of this process, recognizing their critical role as leaders, innovators, and change agents.

What, then, does it truly mean to bridge the gap?

It means ensuring that evidence is not confined to guidelines, publications, or policy documents, but is reflected in every clinical decision and every patient interaction. It means creating systems that support consistency, reduce variability, and promote accountability. It means fostering cultures that value inquiry, embrace change, and prioritize excellence. Most importantly, it means committing to action. The time for incremental progress has passed. The challenges we face require bold thinking, decisive leadership, and sustained effort [10].

This special issue is both a reflection of where we are and a vision of where we need to go. It challenges us to move beyond knowing, to doing; beyond intention, to impact. It calls on all of us – clinicians, educators, researchers, executives, managers, and policymakers – to work together to ensure that evidence-based practice is not the exception, but the standard.

The future of nursing will not be defined by what we know, but by what we implement.
