Problem based learning is used in many medical schools in the United Kingdom and worldwide. This article describes this method of learning and teaching in small groups and explains why it has had an important impact on medical education.

The group learning process: acquiring desirable learning skills

In problem based learning (PBL) students use “triggers” from the problem case or scenario to define their own learning objectives. Subsequently they do independent, self directed study before returning to the group to discuss and refine their acquired knowledge. Thus, PBL is not about problem solving per se, but rather it uses appropriate problems to increase knowledge and understanding. The process is clearly defined, and the several variations that exist all follow a similar series of steps.

#### Generic skills and attitudes

Group learning facilitates not only the acquisition of knowledge but also several other desirable attributes, such as communication skills, teamwork, problem solving, independent responsibility for learning, sharing information, and respect for others. PBL can therefore be thought of as a small group teaching method that combines the acquisition of knowledge with the development of generic skills and attitudes. Presentation of clinical material as the stimulus for learning enables students to understand the relevance of underlying scientific knowledge and principles in clinical practice.

However, when PBL is introduced into a curriculum, several other issues for curriculum design and implementation need to be tackled. PBL is generally introduced in the context of a defined core curriculum and integration of basic and clinical sciences. It has implications for staffing and learning resources and demands a different approach to timetabling, workload, and assessment. PBL is often used to deliver core material in non-clinical parts of the …

Problem based learning

Objective To explore in depth how primary care clinicians (general practitioners and practice nurses) derive their individual and collective healthcare decisions. Design Ethnographic study using standard methods (non-participant observation, semistructured interviews, and documentary review) over two years to collect data, which were analysed thematically. Setting Two general practices, one in the south of England and the other in the north of England. Participants Nine doctors, three nurses, one phlebotomist, and associated medical staff in one practice provided the initial data; the emerging model was checked for transferability with general practitioners in the second practice. Results Clinicians rarely accessed and used explicit evidence from research or other sources directly, but relied on “mindlines”—collectively reinforced, internalised, tacit guidelines. These were informed by brief reading but mainly by their own and their colleagues9 experience, their interactions with each other and with opinion leaders, patients, and pharmaceutical representatives, and other sources of largely tacit knowledge. Mediated by organisational demands and constraints, mindlines were iteratively negotiated with a variety of key actors, often through a range of informal interactions in fluid “communities of practice,” resulting in socially constructed “knowledge in practice.” Conclusions These findings highlight the potential advantage of exploiting existing formal and informal networking as a key to conveying evidence to clinicians.

Evidence based guidelines or collectively constructed “mindlines?” Ethnographic study of knowledge management in primary care

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.

What counts as evidence in evidence-based practice?

Background.  Observation is used in research in two ways – structured and unstructured. Which of these methods to choose depends on the research question but will be defined predominantly by the paradigm underlying each study. Positivistic research generally uses structured observation and interpretist/naturalistic paradigms use unstructured observation. This paper is concerned with unstructured observation.

Aim.  To discuss the importance of unstructured observation as a research method and to examine critically the problems associated with both access and field notes.

Application to nursing.  Although unstructured observation has been used in nursing research, it is less favoured than the interview. Furthermore, although some of the dilemmas concerned with observation such as the role of the researcher, covert research and informed consent have received attention in the nursing literature, other aspects remain relatively unexplored. In particular little has been written concerning access to the field and field notes. Both of these aspects have practical and theoretical considerations that require the attention of the researcher. This omission may partly explain nurses' apparent reluctance to use unstructured observation in their studies. This paper seeks to redress this situation.

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.

Research information in nurses’ clinical decision-making: what is useful?

Aim. To examine those sources of information which nurses find useful for reducing the uncertainty associated with their clinical decisions.

Background. Nursing research has concentrated almost exclusively on the concept of research implementation. Few, if any, papers examine the use of research knowledge in the context of clinical decision-making. There is a need to establish how useful nurses perceive information sources are, for reducing the uncertainties they face when making clinical decisions.

Design. Cross-case analysis involving qualitative interviews, observation, documentary audit and Q methodological modelling of shared subjectivities amongst nurses. The case sites were three large acute hospitals in the north of England, United Kingdom. One hundred and eight nurses were interviewed, 61 of whom were also observed for a total of 180 hours and 122 nurses were involved in the Q modelling exercise.

Results. Text-based and electronic sources of research-based information yielded only small amounts of utility for practising clinicians. Despite isolating four significantly different perspectives on what sources were useful for clinical decision-making, it was human sources of information for practice that were overwhelmingly perceived as the most useful in reducing the clinical uncertainties of nurse decision-makers.

Conclusions. It is not research knowledge per se that carries little weight in the clinical decisions of nurses, but rather the medium through which it is delivered. Specifically, text-based and electronic resources are not viewed as useful by nurses engaged in making decisions in real time, in real practice, but those individuals who represent a trusted and clinically credible source are. More research needs to be carried out on the qualities of people regarded as clinically important information agents (specifically, those in clinical nurse specialist and associated roles) whose messages for practice appear so useful for clinicians.

Research information in nurses’ clinical decision‐making: what is useful?

Background. The successful dissemination of the results of the National Health Service (NHS) research and development strategy and the development of evidence based approaches to health care rely on clinicians having access to the best available evidence; evidence fit for the purpose of reducing the uncertainties associated with clinical decisions. Aim. To reveal the accessibility of those sources of information actually used by nurses, as well as those which they say they use. Design. Mixed method case site, using interview, observational, Q sort and documentary audit data in medical, surgical and coronary care units (CCUs) in three acute hospitals. Results. Three perspectives on accessibility were identified: (a) the humanist-in which human sources of information were the most accessible; (b) local information for local needs-in which locally produced resources were seen as the most accessible and (c) moving towards technology-in which information technology begins to be seen as accessible. Nurses' experience in a clinical specialty is positively associated with a perception that human sources such clinical nurse specialists, link nurses, doctors and experienced clinical colleagues are more accessible than text based sources. Clinical specialization is associated with different approaches to accessing research knowledge. Coronary care unit nurses were more likely perceive local guidelines, protocols and on-line databases as more accessible than their counterparts in general medical and surgical wards. Only a third of text-based resources available to nurses oil the wards had any explicit research base. These, and the remainder were Out of date (mean age of textbooks 11 years), and authorship hard to ascertain. Conclusion. A strategy to increase the use of research evidence by nurses should harness the influence of clinical nurse specialists, link nurses and those engaged in practice development. These roles Could act as 'conduits' through which research-based messages for practice, and information for clinical decision making, could flow. This role should be explored and enhanced.

The accessibility of research-based knowledge for nurses in United Kingdom acute care settings.

To ensure effective utilization of research in nursing more evidence is needed which illuminates the way nurses think about research, the value which they put on it, and how they envisage that it may help or hinder them in their everyday work. This English study aimed to meet these objectives by describing the research culture of practising nurses, health visitors and midwives, and their managers. It rests on two assumptions. Firstly that the reasons why practitioners do, or do not, base their practice on research are complex, and secondly, that interventions to increase research utilization must be grounded in an appreciation of this complex ‘whole’. Thus the study took a qualitative approach to exploring: what participants thought and felt about research; the current status of research based practice; and the opportunities and constraints to increasing research based practice. The results confirm the hypothesis that many factors, both individual and organizational affect research utilization. Furthermore, practitioners and managers hold differing perceptions regarding the nature of research, its role, and the opportunities and constraints which effect its dissemination and utilization. The implications of the results for education, policy and practice are discussed.
