Evidence-based practice: issues, paradigms, and future pathways

Evidence‐based practice (EBP) has become a real buzz word, not only in the discipline of nursing, but in all healthcare professions. EBP has been identified as the foundation of accountable, professional nursing practice and it would seem that few could argue with the apparent benefits; however, debate does exist in the literature about whether EBP can realistically be attained. As such, a critical discourse regarding the future of EBP for nursing needs to occur. One of the key questions to be addressed through this discourse is, “what counts as evidence?” A review of the nursing literature on the concept of EBP will be presented in this paper along with a discussion of several of the issues associated with EBP within the discipline of nursing. I will also present some ideas about the implications of the EBP movement in nursing and examine the future pathways for nursing.     

Evidence-based practice: tap water cleansing of leg ulcers in the community

? To establish and encourage wound management practices based on evidence, a Community Nursing Organization in metropolitan Adelaide began a series of research initiatives in 1997. ? Based on the results of a wound management survey, and through the processes of participatory action research with clinicians, many wound management practice changes were instigated throughout the Community Nursing Organization. ? One question remains unanswered: What is the evidence for the use of sterile saline or clean tap water for cleansing of leg ulcers in the community? ? In this paper we describe a project where we applied the three principles of planning, action and evaluation. ? Application of these principles enabled clinicians to collaborate in the search for evidence to support or refute tap water cleansing of leg ulcers. ? To conclude, we report on a pilot research project undertaken to obtain further evidence either to support or refute the use of tap water cleansing for leg ulcers in the community.

Evidence-based practice in Hong Kong: issues and implications in its establishment

Evidence-based practice has been widely discussed in the literature, but it is not common or well adopted in nursing practice, both in Hong Kong and other countries. This article aims to examine the relationships between three important elements of evidence-based practice: systematic reviews, clinical guidelines and protocols. Current issues associated with evidence-based practice in Hong Kong are explored. Specific suggestions are given to researchers, practitioners, managers and academics so that the current situation can be advanced.     

Blending critical realist and emancipatory practice development methodologies: making critical realism work in nursing research

PARLOUR R and MCCORMACK B. Nursing Inquiry 2012; 19: 308-321 Blending critical realist and emancipatory practice development methodologies: making critical realism work in nursing research This paper examines the efficacy of facilitation as a practice development intervention in changing practice within an Older Person setting and in implementing evidence into practice. It outlines the influences exerted by the critical realist paradigm in guiding emancipatory practice development activities and, in particular, how the former may be employed within an emancipatory practice development study to elucidate and increase understanding pertinent to causation and outcomes. The methodology is based upon an emancipatory practice development approach set within a realistic evaluation framework. This allows for systematic analysis of the social and contextual elements that influence the explication of outcomes associated with facilitation. The study is concentrated upon five practice development cycles, within which a sequence of iterative processes is integrated. The authors assert that combining critical realist and emancipatory processes offers a robust and practical method for translating evidence and implementing changes in practice, as the former affirms or falsifies the influence that emancipatory processes exert on attaining culture shift, and enabling transformation towards effective clinical practice. A new framework for practice development is proposed that establishes methodological coherency between emancipatory practice development and realistic evaluation. This augments the existing theoretical bases for both these approaches by contributing new theoretical and methodological understandings of causation.

Evidence‐based nursing: clarifying the concepts for nurses in practice

Aim. To provide a critical analysis of key concepts associated with evidence‐based nursing (EBN) to substantiate an operational definition for nurses to use in practice. Background. Despite the plethora of literature surrounding what evidence‐based nursing is and is not and how it differs from its cousins, evidence‐based medicine and evidence‐based practice, nurses still struggle to get evidence into practice. Several reasons for this have been reported, for example, a lack of understanding about what evidence‐based nursing means or time to engage with and apply the evidence into practice. Design. An in‐depth critical review and synthesis of literature was undertaken. Method. Using the key words; evidence‐based nursing, evidence‐based medicine and evidence‐based practice 496 articles were yielded. These articles were limited to 83. Using Burns and Grove’s (2001) phased approach to reviewing the literature the articles were critically reviewed and categorised into key concepts and themes. Results. The in‐depth critical review and synthesis of the literature demonstrated that evidence‐based nursing could be defined as a distinct concept. The review clearly shows that for evidence‐based nursing to occur, nurses need to be aware of what evidence‐based nursing means, what constitutes evidence, how evidence‐based nursing differs from evidence‐based medicine and evidence‐based practice and what the process is to engage with and apply the evidence. Conclusion. The in‐depth critical review and synthesis of the evidence‐based nursing literature reinforces the need to consolidate a position for nursing in the evidence‐based field. The review confirms that evidence‐based nursing can be defined and conceptualised; however, for nurses to engage and apply with the evidence‐based processes they need to be informed of what these are and how to engage with them in practice. Relevance to clinical practice. This paper examines the concept of evidence‐based nursing and its application to clinical practice.     

Conducting biological research to advance rehabilitation nursing practice.

Rehabilitation nursing practice is concerned with many clinical manifestations that have an underlying biological impairment. Advances in managing these manifestations will depend in part on research that incorporates the biological dimension. The purpose of this article is to encourage more rehabilitation nurses to engage in biological research. To achieve this aim, several different categories of biological nursing research are described using rehabilitation nursing examples, biological measures and approaches are discussed, and possible general clinical outcomes, with examples from previously published biological nursing research, are described. Biological nursing research may enhance professional competence, improve patient care, and improve patient safety.     

Myths and facts about safe patient handling in rehabilitation.

As the incidence of injuries associated with patient-handling tasks remains high in the rehabilitation community, interdisciplinary discussions on optimal methods for preventing injuries and ensuring good care continue. A national task force consisting of representatives from the Association of Rehabilitation Nurses, the American Physical Therapy Association, and the Veterans Health Administration identified myths that have been promulgated on both sides of the discussion, focusing especially on rehabilitation practices. The purpose of this article is to dispel these myths by using evidence-based methods. Evidence should be applied in discussions of safe patient handling, and although concern about patient outcomes is critical, there is no evidence that the use of patient-handling technology undermines rehabilitation goals and strong evidence that these practices enhance the safety of rehabilitation care providers. Further research on the impact of safe patient-handling practices on rehabilitation goals and continued communication between rehabilitation providers are recommended.     

Evidence-based practice in pediatric rehabilitation

EBP is not a new concept. To practice using the newest and best research evidence, clinicians must have the knowledge and skills to find and appraise the quality of the evidence. This process starts with the formulation of a focused question, followed by an effective search for the best evidence, critical appraisal of the evidence retrieved, and integration of that best evidence into practice. There are an increasing number of resources that can provide clinicians with the best evidence and that can assist clinicians with enhancement of their EBP skills. Unique challenges exist in practicing in an evidence-based manner in the field of pediatric rehabilitation, but through the collaboration of clinicians and researchers, these challenges can be overcome.     

Achieving evidence-based nursing practice: impact of the Caledonian Development Model

Aim To determine the impact of the Caledonian Development Model, designed to promote evidence‐based practice. Background The model features practice‐development activities, benchmarking, knowledge pooling and translation through membership of a community of practice and a virtual college. Methods Twenty‐four nurses, from 18 practice sites formed three communities of practice, each selecting evidence‐based guidance to implement. A modified group supervision framework empowered nurses to champion local implementation. Outcomes were determined at 6 months. Results Eighty per cent of the patient‐related criteria and 35% of the facilities criteria were achieved. The Revised Nursing Work Index indicated these nurses experienced greater autonomy (P = 0.019) and increased organizational support (P = 0.037). Focus groups revealed a deepening organizational support for the initiative over time, illuminated work‐based learning challenges and overall enthusiasm for the approach. Conclusion Implementation of the model effectively promoted evidence‐based practice, most notably at the level of the individual patient. Implications for nursing management Time and budgetary constraints necessitate smart, value for money approaches to developing evidence‐based practice and improved care standards. This work demonstrates an effective model that strikes a balance between individual and group learning, virtual and real‐time activities, coupled with resource pooling across organizations and sectors.     

Evidence-based management: a literature review

This paper presents a review of evidence-based management (EBM), exploring whether management activities within healthcare have been, or can be, subject to the same scientific framework as clinical practice. The evidence-based approach was initially examined, noting the hierarchy of evidence ranging from randomized control trials to clinical anecdote. The literature varied in its degree of criticism of this approach; the most common concern referring to the assumed superiority of positivism. However, evidence-based practice was generally accepted as the best way forward. Stewart (1998) offered the only detailed exposition of EBM, outlining a necessary 'attitude of mind' both for EBM and for the creation of a research culture. However, the term 'clinical effectiveness' emerged as a possible replacement buzz-word for EBM (McClarey 1998). The term appears to encompass the sentiments of the evidence-based approach, but with a concomitant concern for economic factors. In this paper the author has examined the divide between those who viewed EBM as an activity for managers to make their own practice accountable and those who believed it to be a facilitative practice to help clinicians with evidence-based practice. Most papers acknowledged the limited research base for management activities within the health service and offered some explanation such as government policy constraints and lack of time. Nevertheless, the overall emphasis is that ideally there should be a management culture firmly based in evidence.
