Resisting medicines: a synthesis of qualitative studies of medicine taking.

The study aimed to synthesise qualitative studies of lay experiences of medicine taking. Most studies focused on the experience of those not taking their medicine as prescribed, with few considering those who reject their medicines or accept them uncritically. Most were concerned with medicines for chronic illnesses. The synthesis revealed widespread caution about taking medicines and highlighted the lay practice of testing medicines, mainly for adverse effects. Some concerns about medicines cannot be resolved by lay evaluation, however, including worries about dependence, tolerance and addiction, the potential harm from taking medicines on a long-term basis and the possibility of medicines masking other symptoms. Additionally, in some cases medicines had a significant impact on identity, presenting problems of disclosure and stigma. People were found to accept their medicines either passively or actively, or to reject them. Some were coerced into taking medicines. Active accepters might modify their regimens by taking medicines symptomatically or strategically, or by adjusting doses to minimise unwanted consequences, or to make the regimen more acceptable. Many modifications appeared to reflect a desire to minimise the intake of medicines and this was echoed in some peoples' use of non-pharmacological treatments to either supplant or supplement their medicines. Few discussed regimen changes with their doctors. We conclude that the main reason why people do not take their medicines as prescribed is not because of failings in patients, doctors or systems, but because of concerns about the medicines themselves. On the whole, the findings point to considerable reluctance to take medicine and a preference to take as little as possible. We argue that peoples' resistance to medicine taking needs to be recognised and that the focus should be on developing ways of making medicines safe, as well as identifying and evaluating the treatments that people often choose in preference to medicines.

Communication between anesthesiologists, patients and the anesthesia team: a descriptive study of induction and emergence.

PURPOSE: Although the importance of communication skills in anesthetic practice is increasingly recognized, formal communication skills training has hitherto dealt only with limited aspects of this professional activity. We aimed to document and analyze the informally-learned communication that takes place between anesthesia personnel and patients at induction of and emergence from general anesthesia. METHODS: We adopted an ethnographic approach based principally on observation of anesthesia personnel at work in the operating theatres with subsequent analysis of observation transcripts. RESULTS: We noted three main styles of communication on induction, commonly combined in a single induction. In order of frequency, these were: (1) descriptive, where the anesthesiologists explained to the patient what he/she might expect to feel; (2) functional, which seemed designed to help anesthesiologists maintain physiological stability or assess the changing depth of anesthesia and (3) evocative, which referred to images or metaphors. Although the talk we have described is nominally directed at the patient, it also signifies to other members of the anesthetic team how induction is progressing. The team may also contribute to the communication behaviour depending on the context. Communication on emergence usually focused on establishing that the patient was awake. CONCLUSION: Communication at induction and emergence tends to fall into specific patterns with different emphases but similar functions. This communication work is shared across the anesthetic team. Further work could usefully explore the relationship between communication styles and team performance or indicators of patient safety or well-being.

Safe asleep? Human-machine relations in medical practice.

In the process of anaesthesia the patient must surrender vital functions to the care of clinicians and machines who will act for, and advocate for the patient during the surgical procedure. In this paper, we discuss the practices and knowledge sources that underpin safety in a risky field in which many boundaries are crossed and dissolved. Anaesthetic practice is at the frontier not only of conscious/unconsciousness but is also at the human/machine frontier, where a range of technologies acts as both delegates and intermediaries between patient and practitioner. We are concerned with how practitioners accommodate and manage these shifting boundaries and what kinds of knowledge sources the 'expert' must employ to make decisions. Such sources include clinical, social and electronic which in their various forms demonstrate the hybrid and collective nature of anaesthetised patients. In managing this collective, the expert is one who is able to judge where the boundary lies between what is routine and what is critical in practice, while the junior must judge the personal limits of expertise in practice. In exploring the working of anaesthetic hybrids, we argue that recognising the changing distribution of agency between humans and machines itself illustrates important features of human authorship and expertise.

Conducting ethnography in medical settings.

BACKGROUND: Ethnographic research methods have a considerable history of use in medical settings. This paper provides a personal account of conducting ethnography in medical environments and focuses on some of the practical and ethical issues encountered in such settings. DISCUSSION AND CONCLUSION: The paper describes particular issues that arise when undertaking ethnographic work, such as gaining access, recording data, research roles and researching elite groups, and recounts some of the dilemmas posed by doing this type of research in a medical setting. The paper concludes by reflecting on what ethnography might offer to medicine in return for the rich data medicine provides.

Access, boundaries and their effects: legitimate participation in anaesthesia.

The distribution of work, knowledge and responsibilities in the delivery of anaesthesia has attained particular significance recently as attempts to meet the demands of the European Working Times Directive intensify existing pressures to reorganise anaesthetic services. Using Lave and Wenger's (1991) notions of 'legitimate peripheral participation' in 'communities of practice' (and Wenger 1998) to analyse ethnographic data of anaesthetic practice we illustrate how work and knowledge are currently configured, and when knowledge may legitimately be taken as the basis for action. The ability to initiate action, to prescribe healthcare interventions, we suggest, is a critical element in the organisation of anaesthetic practices and therefore central to any attempts to reshape the delivery of anaesthetic services.

Systematically reviewing qualitative and quantitative evidence to inform management and policy-making in the health field.

Policy-makers and managers have always used a wide range of sources of evidence in making decisions about policy and the organization of services. However, they are under increasing pressure to adopt a more systematic approach to the utilization of the complex evidence base. Decision-makers must address complicated questions about the nature and significance of the problem to be addressed; the nature of proposed interventions; their differential impact; cost-effectiveness; acceptability and so on. This means that Cochrane-style reviews alone are not sufficient. Rather, they require access to syntheses of high-quality evidence that include research and non-research sources, and both qualitative and quantitative research findings. There is no single, agreed framework for synthesizing such diverse forms of evidence and many of the approaches potentially applicable to such an endeavour were devised for either qualitative or quantitative synthesis and/or for analysing primary data. This paper describes the key stages in reviewing and synthesizing qualitative and quantitative evidence for decision-making and looks at various strategies that could offer a way forward. We identify four basic approaches: narrative (including traditional 'literature reviews' and more methodologically explicit approaches such as 'thematic analysis', 'narrative synthesis', 'realist synthesis' and 'meta-narrative mapping'), qualitative (which convert all available evidence into qualitative form using techniques such as 'meta-ethnography' and 'qualitative cross-case analysis'), quantitative (which convert all evidence into quantitative form using techniques such as 'quantitative case survey' or 'content analysis') and Bayesian meta-analysis and decision analysis (which can convert qualitative evidence such as preferences about different outcomes into quantitative form or 'weights' to use in quantitative synthesis). The choice of approach will be contingent on the aim of the review and nature of the available evidence, and often more than one approach will be required.

Identification of a minimal promoter sequence for the human N-acetyltransferase Type I gene that binds AP-1 (activator protein 1) and YY-1 (Yin and Yang 1).

Human N -acetyltransferase Type I (NAT1) catalyses the acetylation of many aromatic amine and hydrazine compounds and it has been implicated in the catabolism of folic acid. The enzyme is widely expressed in the body, although there are considerable differences in the level of activity between tissues. A search of the mRNA databases revealed the presence of several NAT1 transcripts in human tissue that appear to be derived from different promoters. Because little is known about NAT1 gene regulation, the present study was undertaken to characterize one of the putative promoter sequences of the NAT1 gene located just upstream of the coding region. We show with reverse-transcriptase PCR that mRNA transcribed from this promoter (Promoter I) is present in a variety of human cell-lines, but not in quiescent peripheral blood mononuclear cells. Using deletion mutant constructs, we identified a 20 bp sequence located 245 bases upstream of the translation start site which was sufficient for basal NAT1 expression. It comprised an AP-1 (activator protein 1)-binding site, flanked on either side by a TCATT motif. Mutational analysis showed that the AP-1 site and the 3' TCATT sequence were necessary for gene expression, whereas the 5' TCATT appeared to attenuate promoter activity. Electromobility shift assays revealed two specific bands made up by complexes of c-Fos/Fra, c-Jun, YY-1 (Yin and Yang 1) and possibly Oct-1. PMA treatment enhanced expression from the NAT1 promoter via the AP-1-binding site. Furthermore, in peripheral blood mononuclear cells, PMA increased endogenous NAT1 activity and induced mRNA expression from Promoter I, suggesting that it is functional in vivo.

Women's views on the impact of operative delivery in the second stage of labour: qualitative interview study.

OBJECTIVE: To obtain the views of women on the impact of operative delivery in the second stage of labour. DESIGN: Qualitative interview study. SETTING: Two urban teaching hospitals in the United Kingdom. PARTICIPANTS: Purposive sample of 27 women who had undergone operative delivery in the second stage of labour between January 2000 and January 2002. KEY THEMES: Preparation for birth, understandings of the indications for operative delivery, and explanation or debriefing after birth. RESULTS: The women felt unprepared for operative delivery and thought that their birth plan or antenatal classes had not catered adequately for this event. They emphasised the importance of maintaining an open mind about the management of labour. They had difficulty understanding the need for operative delivery despite a review by medical and midwifery staff before discharge. Operative delivery had a noticeable impact on women's views about future pregnancy and delivery. CONCLUSIONS: Women consider postnatal debriefing and medical review important deficiencies in current care. Those who experienced operative delivery in the second stage of labour would welcome the opportunity to have a later review of their intrapartum care, physical recovery, and management of future pregnancies.

Evaluating meta-ethnography: a synthesis of qualitative research on lay experiences of diabetes and diabetes care.

Interest in how qualitative health research might be used more widely to inform health policy and medical practice is growing. Synthesising findings from individual qualitative studies may be one method but application of conventional systematic review methodology to qualitative research presents significant philosophical and practical challenges. The aim here was to examine the feasibility of synthesising qualitative research using qualitative methodology including a formative evaluation of criteria for assessing the research to be synthesised. Ten qualitative studies of adult patients' perspectives of diabetes were purposefully selected and questions proposed by the critical appraisal skills programme (CASP) adapted and used to assess papers prior to synthesis. Each study was reviewed independently by two experienced social scientists. The level of agreement between reviewers was determined. Three papers were excluded: one because it turned out not to be qualitative research, one because the quality of the empirical work was poor and one because the qualitative findings reported were also recorded in another paper already included. The synthesis, which had two distinct elements, was conducted using the meta-ethnographic method. Firstly, four papers containing typologies of patient responses to diabetes were synthesised. Secondly, six key concepts were identified from all seven papers as being important in enabling a person with diabetes to achieve a balance in their lives and to attain a sense of well-being and control. These included: time and experience, trust in self, a less subservient approach to care providers, strategic non-compliance with medication, effective support from care providers and an acknowledgement that diabetes is serious. None of the studies included in the synthesis referenced any of the early papers nor did they appear to have taken account of or built upon previous findings. This evaluation confirmed that meta-ethnography can lead to a synthesis and extension of qualitative research in a defined field of study. In addition, from it a practical method of qualitative research assessment evolved. This process is promising but requires further testing and evaluation before it could be recommended for more widespread adoption.

Passing on tacit knowledge in anaesthesia: a qualitative study.

OBJECTIVE: To explore the acquisition of knowledge in anaesthetic practice using qualitative methods. METHODS: An ethnographic study examining the nature of expertise in anaesthesia in one English hospital. The study used qualitative research methods, including observation of anaesthetic practice and interviews with members of the anaesthetic team. An integral part of the study was a process of feedback to the anaesthetic team including presenting observational data and conducting debriefing interviews with individual team members. RESULTS: The study highlights the continued importance of the clinical apprenticeship in passing on knowledge, but also emphasizes the central role of practising independently in the acquisition of skills. Anaesthetists who participated in debriefing interviews or read observational transcripts found the experience valuable for thinking about their own practice. DISCUSSION: One suggestion arising from the use of qualitative methods in this setting is that the type of detailed, systematic observation and data recording used in this study could be beneficial in the training and, possibly, appraisal of anaesthetists. This novel and innovative application of qualitative methods in anaesthesia is described and discussed with a view to broadening the debate about specialist training.

Ethics and ethnography: an experiential account.

In this article, the authors discuss an ethical dilemma faced by the first author during the fieldwork of an ethnographic study of expertise in anesthesia. The example, written from the perspective of the first author, addresses a number of ethical issues commonly faced, namely, the researcher-researched relationship, anonymity and confidentiality, privacy, and exploitation. She deliberates on the influences that guided her decision and in doing so highlights some of the elements that combine to shape the data. The authors argue that this process of shaping the data is a symbiotic one in which the researcher and the community being studied construct the data together.

'I saw the panic rise in her eyes, and evidence-based medicine went out of the door.' An exploratory qualitative study of the barriers to secondary prevention in the management of coronary heart disease.

UNLABELLED: Background. Coronary heart disease (CHD) is the leading cause of death in the UK, yet only 50% of CHD patients receive appropriate secondary prevention. Objectives. To explore GP attitudes to evidence about CHD, and to identify factors influencing the implementation of secondary prevention in GP consultations. METHODS: Semi-structured interviews and focus groups exploring consultations with patients previously diagnosed as having CHD. RESULTS: Use of evidence is influenced by credibility. Lack of time was the greatest barrier to accessing evidence and to implementing secondary prevention. Patients were more likely to receive secondary prevention in a dedicated clinic. Patient characteristics including physical and mental co-morbidity mitigate against secondary prevention. GPs experienced difficulty balancing implementation of evidence with the demands of the doctor-patient relationship. CONCLUSIONS: The doctor-patient relationship may act as a barrier to the delivery of secondary prevention in primary care. It may be time to re-evaluate models of these relationships and reconsider the strategies for implementing evidence.

Using meta ethnography to synthesise qualitative research: a worked example.

OBJECTIVES: To demonstrate the benefits of applying meta ethnography to the synthesis of qualitative research, by means of a worked example. METHODS: Four papers about lay meanings of medicines were arbitrarily chosen. Noblit and Hare's seven-step process for conducting a meta ethnography was employed: getting started; deciding what is relevant to the initial interest; reading the studies; determining how the studies are related; translating the studies into one another; synthesising translations; and expressing the synthesis. RESULTS: Six key concepts were identified: adherence/compliance; self-regulation; aversion; alternative coping strategies; sanctions; and selective disclosure. Four second-order interpretations (derived from the chosen papers) were identified, on the basis of which four third-order interpretations (based on the key concepts and second-order interpretations) were constructed. These were all linked together in a line of argument that accounts for patients' medicine-taking behaviour and communication with health professionals in different settings. Third-order interpretations were developed which were not only consistent with the original results but also extended beyond them. CONCLUSIONS: It is possible to use meta ethnography to synthesise the results of qualitative research. The worked example has produced middle-range theories in the form of hypotheses that could be tested by other researchers.

Patients' help-seeking experiences and delay in cancer presentation: a qualitative synthesis.

BACKGROUND: The reduction of delay in cancer diagnosis has been targeted as a way to improve survival. We undertook a qualitative synthesis of international research evidence to provide insight into patients' experiences of recognising symptoms of cancer and seeking help. METHODS: We searched international publications (1985-2004) for delay in cancer diagnosis to identify the relevant qualitative research, and used meta-ethnography to identify the common themes across the studies. Our synthesis interpreted individual studies by identification of second-order constructs (interpretations offered by the original researchers) and third-order constructs (development of new interpretations beyond those offered in individual studies). FINDINGS: We identified 32 papers (>775 patients and carers) reporting help-seeking experiences for at least 20 different types of cancer. The analysis showed strong similarities in patients with different cancer types. Key concepts were recognition and interpretation of symptoms, and fear of consultation. Fear manifested as a fear of embarrassment (the feeling that symptoms were trivial or that symptoms affected a sensitive body area), or a fear of cancer (pain, suffering, and death), or both. Such analyses allowed exploration of third-order constructs. The patient's gender and the sanctioning of help-seeking were important factors in prompt consultation. INTERPRETATION: Strategies to understand and reduce patients' delay in cancer presentation can help symptom recognition but need to address patients' anxieties. The effect of the patient's sex in help-seeking also needs to be recognised, as does the important role of friends, family, and health-care professionals in the sanctioning of consultation. This meta-ethnography provides an international overview through the systematic synthesis of a diverse group of small-scale qualitative studies.

NHS walk-in centres and the expanding role of primary care nurses.

Forty pilot NHS walk-in centres have opened over the past two years to provide drop-in nurse-led primary care in England without the input of doctors. As such, these centres represent a revolution for nurse-led care in the health service. However, research suggests that there is considerable variation in the degree of autonomy and independence exercised by the nurses in the different centres. This article discusses this variation, the role of walk-in centre nurses and how this might develop in future.
