An exploration of the factors that influence the implementation of evidence into practice

BACKGROUND

The challenges of implementing evidence-based practice are complex and varied. Against this background a framework has been developed to represent the multiple factors that may influence the implementation of evidence into practice. It is proposed that successful implementation is dependent upon the nature of the evidence being used, the quality of context, and, the type of facilitation required to enable the change process. This study sets out to scrutinize the elements of the framework through empirical enquiry.

AIMS AND OBJECTIVES

The aim of the study was to address the following questions: * What factors do practitioners identify as the most important in enabling implementation of evidence into practice? * What are the factors practitioners identify that mediate the implementation of evidence into practice? * Do the concepts of evidence, context and facilitation constitute the key elements of a framework for getting evidence into practice?

DESIGN AND METHODS

The study was conducted in two phases. Phase 1: Exploratory focus groups (n = 2) were conducted to inform the development of an interview guide. This was used with individual key informants in case study sites. Phase 2: Two sites with on-going or recent implementation projects were studied. Within sites semi-structured interviews were conducted (n = 17).

RESULTS

A number of key issues in relation to the implementation of evidence into practice emerged including: the nature and role of evidence, relevance and fit with organizational and practice issues, multi-professional relationships and collaboration, role of the project lead and resources.

CONCLUSIONS

The results are discussed with reference to the wider literature and in relation to the on-going development of the framework. Crucially the growing body of evidence reveals that a focus on individual approaches to implementing evidence-based practice, such as skilling-up practitioners to appraise research evidence, will be ineffective by themselves.

RELEVANCE TO CLINICAL PRACTICE

Key elements that require attention in implementing evidence into practice are presented and may provide a useful checklist for future implementation and evaluation projects.

The research agenda for protocol-based care

BACKGROUND

Protocol-based care is increasingly being used to deliver collaborative, integrated and improved patient-centred care, based on the best available evidence. This article provides an overview of key issues arising from protocol-based care literature to illustrate the research agenda for this important care delivery approach.

CONCLUSION

Protocols provide great potential to deliver best practice. However, questions remain about the benefits of protocol-based care.

What counts as evidence in evidence-based practice?

BACKGROUND

Considerable financial and philosophical effort has been expended on the evidence-based practice agenda. Whilst few would disagree with the notion of delivering care based on information about what works, there remain significant challenges about what evidence is, and thus how practitioners use it in decision-making in the reality of clinical practice.

AIM

This paper continues the debate about the nature of evidence and argues for the use of a broader evidence base in the implementation of patient-centred care.

DISCUSSION

Against a background of financial constraints, risk reduction, increased managerialism research evidence, and more specifically research about effectiveness, have assumed pre-eminence. However, the practice of effective nursing, which is mediated through the contact and relationship between individual practitioner and patient, can only be achieved by using several sources of evidence. This paper outlines the potential contribution of four types of evidence in the delivery of care, namely research, clinical experience, patient experience and information from the local context. Fundamentally, drawing on these four sources of evidence will require the bringing together of two approaches to care: the external, scientific and the internal, intuitive.

CONCLUSION

Having described the characteristics of a broader evidence base for practice, the challenge remains to ensure that each is as robust as possible, and that they are melded coherently and sensibly in the real time of practice. Some of the ideas presented in this paper challenge more traditional approaches to evidence-based practice. The delivery of effective, evidence-based patient-centred care will only be realized when a broader definition of what counts as evidence is embraced.

Ingredients for change: revisiting a conceptual framework

Finding ways to deliver care based on the best possible evidence remains an ongoing challenge. Further theoretical developments of a conceptual framework are presented which influence the uptake of evidence into practice. A concept analysis has been conducted on the key elements of the framework--evidence, context, and facilitation--leading to refinement of the framework. While these three essential elements remain key to the process of implementation, changes have been made to their constituent sub-elements, enabling the detail of the framework to be revised. The concept analysis has shown that the relationship between the elements and sub-elements and their relative importance need to be better understood when implementing evidence based practice. Increased understanding of these relationships would help staff to plan more effective change strategies. Anecdotal reports suggest that the framework has a good level of validity. It is planned to develop it into a practical tool to aid those involved in planning, implementing, and evaluating the impact of changes in health care.

Getting evidence into practice: ingredients for change

Mounting pressure is being exerted to ensure that the delivery of care is evidence-based and clinically effective. However, the challenge this presents to practitioners is complex. The authors propose that successful implementation of evidence into practice is a function of three elements: the nature of the evidence; the context in which the change is to take place; and the way the process is managed. A framework has been developed to represent these factors. For those about to embark on implementation work, this article closes by highlighting a number of key questions for consideration, stimulated by the framework.

Getting evidence into practice: the meaning of 'context'

AIM OF PAPER

This paper presents the findings of a concept analysis of 'context' in relation to the successful implementation of evidence into practice.

BACKGROUND

In 1998, a conceptual framework was developed that represented the interplay and interdependence of the many factors influencing the uptake of evidence into practice [Kitson A., Harvey G. & McCormack B. (1998) Quality in Health Care 7, 149]. One of the key elements of the framework was 'context', that is, the setting in which evidence is implemented. It was proposed that key factors in the context of health care practice had a significant impact on the implementation and uptake of evidence. As part of the on-going development and refinement of the framework, the elements within it have undergone a concept analysis in order to provide some theoretical and conceptual rigour to its content.

METHODS

Morse's [Morse J.M. (1995) Advances in Nursing Science 17, 31; Morse J.M., Hupcey J.E. & Mitcham C. (1996) Scholarly Inquiry for Nursing Practice. An International Journal 10, 253] approach to concept analysis was used as a framework to review semi-nal texts critically and the supporting research literature in order to establish the conceptual clarity and maturity of 'context' in relation to its importance in the implementation of evidence-based practice.

FINDINGS

Characteristics of the concept of context in terms of organizational culture, leadership and measurement are outlined. A main finding is that context specifically means 'the setting in which practice takes place', but that the term itself does little to reflect the complexity of the concept. Whilst the themes of culture and leadership are central characteristics of the concept, the theme of 'measurement' is better articulated through the broader term of 'evaluation'.

CONCLUSIONS

There is inconsistency in the use of the term and this has an impact on claims of its importance. The concept of context lacks clarity because of the many issues that impact on the way it is characterized. Additionally, there is limited understanding of the consequences of working with different contexts. Thus, the implications of using context as a variable in research studies exploring research implementation are as yet largely unknown. The concept of context is partially developed but in need of further delineation and comparison.

Getting evidence into practice: the role and function of facilitation

AIM OF PAPER

This paper presents the findings of a concept analysis of facilitation in relation to successful implementation of evidence into practice.

BACKGROUND

In 1998, we presented a conceptual framework that represented the interplay and interdependence of the many factors influencing the uptake of evidence into practice. One of the three elements of the framework was facilitation, alongside the nature of evidence and context. It was proposed that facilitators had a key role in helping individuals and teams understand what they needed to change and how they needed to change it. As part of the on-going development and refinement of the framework, the elements within it have undergone a concept analysis in order to provide theoretical and conceptual clarity.

METHODS

The concept analysis approach was used as a framework to review critically the research literature and seminal texts in order to establish the conceptual clarity and maturity of facilitation in relation to its role in the implementation of evidence-based practice.

FINDINGS

The concept of facilitation is partially developed and in need of delineation and comparison. Here, the purpose, role and skills and attributes of facilitators are explored in order to try and make distinctions between this role and other change agent roles such as educational outreach workers, academic detailers and opinion leaders.

CONCLUSIONS

We propose that facilitation can be represented as a set of continua, with the purpose of facilitation ranging from a discrete task-focused activity to a more holistic process of enabling individuals, teams and organizations to change. A number of defining characteristics of facilitation are proposed. However, further research to clarify and evaluate different models of facilitation is required.

Formal consensus: the development of a national clinical guideline

BACKGROUND

There is currently a political enthusiasm for the development and use of clinical guidelines despite, paradoxically, there being relatively few healthcare issues that have a sound research evidence base. As decisions have to be made even where there is an undetermined evidence base and that limiting recommendations to where evidence exists may reduce the scope of guidelines, thus limiting their value to practitioners, guideline developers have to rely on various different sources of evidence and adapt their methods accordingly. This paper outlines a method for guideline development which incorporates a consensus process devised to tackle the challenges of a variable research evidence base for the development of a national clinical guideline on risk assessment and prevention of pressure ulcers.

METHOD

To inform the recommendations of the guideline a formal consensus process based on a nominal group technique was used to incorporate three strands of evidence: research, clinical expertise, and patient experience.

RESULTS

The recommendations for this guideline were derived directly from the statements agreed in the formal consensus process and from key evidence-based findings from the systematic reviews. The existing format of the statements that participants had rated allowed a straightforward revision to "active" recommendations, thus reducing further risk of subjectivity entering into the process.

CONCLUSIONS

The method outlined proved to be a practical and systematic way of integrating a number of different evidence sources. The resultant guideline is a mixture of research based and consensus based recommendations. Given the lack of available guidance on how to mix research with expert opinion and patient experiences, the method used for the development of this guideline has been outlined so that other guideline developers may use, adapt, and test it further.

Consumerism in health care: the case of medication education

BACKGROUND

The United Kingdom government's policy documents spanning the last decade clearly envisage the patient as a consumer of health care. In this context this paper discusses recent research findings related to the health-promotion practice of medication delivered by nurses in England in a variety of health care settings. Literature exploring consumerism in health care highlights a number of principles which were used to develop a framework to evaluate the data collected in this study.

METHOD

Non-participant observation and audio-recordings of nurse-patient interactions about medications were collected in seven different contexts focusing on adults, older people, mental health and community nurse settings. Post-interaction interviews with nurse and patient participants were conducted to explore views on quality, satisfaction with, and intended outcomes of, the interactions.

FINDINGS

Generally, the findings demonstrated that the espoused theory and practice reality regarding the carrying out of consumerist principles are incongruous. Interactions contained relatively simple information, were dominated and led by nurses and offered little opportunity for patient choice. Patients, however, expressed a satisfaction with minimal information and involvement.

CONCLUSION

The findings are discussed with reference to a number of different contextual factors: acuity of illness, perceived balance of power, information gaps, patterns of contact and nurse-patient relationships, and patient-centred care.

Nurses' educational preparation for a medication education role: findings from a national survey

Nurses have a potentially important contribution to make to educating patients about medications. This nursing role is likely to acquire increasing significance as the number of nurses independently prescribing medicines grows, in addition to those nurses occupying autonomous and extended roles that involve ongoing assessment and monitoring of patients' medicine-taking behaviour. As part of a study(1)commissioned to evaluate nurses' educational preparation for, and practice of, medication education, a national survey of nurse education institutions was undertaken. A postal questionnaire was distributed to identified individuals within 51 education institutions in England. Respondents were asked about a number of curriculum design and delivery factors related to subjects central to medication education: pharmacology, patient education and communication skills. Analysis highlighted a number of themes: the teaching of pharmacology is generally integrated within other curricular modules; respondents were dissatisfied with insufficient curricular time devoted to taught pharmacology; the importance of lecturers' ability to apply theory to practice; a lack of clarity concerning pharmacology learning outcomes applied to medication education; and respondents' perceptions that opportunities for integrating pharmacology knowledge, patient education and communication skills were available within practice settings. The significance and implications of the findings are discussed in the context of current educational policy.

Nursing, medication education and the new policy agenda: the evidence base

Current social and demographic trends, combined with 'the new policy agenda', highlight the importance of nurses' role in educating patients about medication. In the absence of previous research investigation, this study set out to explore nurses' current contribution to medication education and the clinical contextual factors that influence current practice. The evidence base for effective medication education was established from reviews of literature and focus groups with key informants. Nurses' practice was investigated using a case study approach in seven clinical areas representing adult, care of the older person, mental health and community nursing contexts. Methods used to collect data were: audio-recordings (n=37) and observation (n=48) of nurse-patient interactions about medication, post-interaction interviews with nurses (n=29), post-interaction interviews with patients (n=39), analysis of relevant written documentation and researcher observation and field notes. Data sources within each case were subjected to systematic content analysis in order to identify current practice and contextual influences within each case. Cross-case analysis was also employed in order to identify explanations for any differentiation in practice. Findings indicate that nurses' contribution to medication education is commonly limited to simple information giving about medicines, involving the name, purpose, colour, number of tablets and the time and frequency that medications should be administered. Nurses' practice in two of the seven clinical areas was characterised by interactions that more closely demonstrated features of what is known to constitute more comprehensive and effective medication education. Analysis of contextual influences within and between cases allowed explanations to be derived for the types of medication education interactions observed. These concerned: patient characteristics, perceived and expressed preferences of patients for information, characteristics of the nurse-patient relationship, lack of time and high workload, and the philosophy of care within the clinical area. In all clinical areas, nurses were not explicitly and judiciously using available evidence to inform their medication-related interactions. The paper concludes with discussion and implications of the findings.

Evaluating educational preparation for a health education role in practice: the case of medication education

Current health care policy and practice contexts in the UK point to the importance of nurses' ability to make an effective contribution to educating patients about medication, as part of their role in health education and health promotion. Nurses' potential contribution to this important activity will inevitably be dependent on knowledge and skills acquired during preregistration and postregistration programmes of education. Against this backdrop, changes in pre and postregistration nurse education in the UK in the past decade highlight the importance and timeliness of evaluating the adequacy of educational preparation for a medication role. This paper reports on the findings from an evaluation of UK educational preparation for a medication education role in practice. A case study design was used to investigate current educational preparation at three education institutions. Multiple methods of data collection at each site involved focus group discussions with lecturers and practitioners, individual interviews with key personnel, nonparticipant observation of teaching sessions, postobservation interviews with students and curriculum analysis. Findings highlighted the importance of a number of dimensions of preparation for practice of such a role: the need for sufficient taught pharmacology; opportunities for application and integration of prerequisite knowledge and skills; the importance of practice-based learning; the need for an evidence-based curriculum, and the importance of clarifying outcomes and competencies required for a medication education role within pre and postregistration curricula. The paper concludes with a discussion and implications of the findings.

Developing clinical guidelines: issues and challenges

Clinical guidelines are viewed as an important tool in the quest to promote evidence based practice. Consequently, there has been a proliferation in guideline development at a national and local level. This paper describes what clinical guidelines are and how they have been developed by a national organisation--the Royal College of Nursing (RCN). Drawing on the development of two tissue viability guidelines: The Management of Patients with Venous Leg Ulcers and Risk Assessment and Prevention of Pressure Ulcers, some challenges inherent in guideline development are outlined. Certain desirable attributes that a clinical guideline should exhibit in order for it to be utilisable and effective in practice are outlined as these provide a standard for guideline developers. In reality the practice of guideline development will depend upon the topic, the experience of the guideline group, the purpose of the guidelines and the evidence available. Our experience suggests that producing a clinically valid and utilisable guideline is a labour and resource intensive process. It is also time consuming. An alternative strategy to developing local guidelines from scratch would be to adapt an existing guideline to local circumstances. A stepwise process is presented in the paper to assist people with this process.

Nursing and medication education

AIM

This study set out to explore nurses' current contribution to medication education and the clinical contextual factors that influence current practice.

METHOD

Nurses' practice was investigated using a case study approach. Methods used to collect data were: audio-recordings and observation of nurse-patient interactions about medication, post-interaction interviews with nurses and patients, analysis of relevant written documentation and researcher observation and field notes.

RESULTS

Findings indicate that nurses' contribution to medication education is commonly limited to giving simple information about medicines, involving the name, purpose, colour, number of tablets and the time and frequency for their administration.

CONCLUSION

Nurse-patient relationships, patterns of contact and philosophy of care were all identified as contributory factors to enabling the practice of medication education in clinical areas.
