Asking well-built questions for evidence-based practice in augmentative and alternative communication.

UNLABELLED: Evidence-based practice (EBP) is increasingly being advocated as the preferred approach to practice in augmentative and alternative communication (AAC). The EBP process involves multiple steps. The asking of a well-built question is the first step in the quest for answers. At the same time it is also often the first stumbling block for practitioners. To facilitate the asking of well-built questions it may be helpful to follow a template. The most frequently used template is PICO, which stands for patient, intervention, comparison, and outcome [Richardson, W., Wilson, M., Nishikawa, J., & Hayward, R. (1995). The well-built clinical question: A key to evidence-based decisions. ACP Journal Club, 123, A12-A13]. In this article, we examine the suitability of the PICO template for AAC in terms of the representativeness of the components, and the appropriateness of its subcomponents, and their terminology. Based on this analysis, we propose the PESICO template, which stands for person, environments, stakeholders, intervention, comparison, and outcome. This template is then illustrated with examples representing a range of decision-making areas in AAC. Finally, directions for future research are provided. LEARNING OUTCOMES: The reader will be able to: (1) appreciate the importance of asking well-built questions, (2) name the shortcomings of the PICO template, and (3) describe the components of the proposed PESICO template for asking well-built questions.

Dying well: nurses' experiences of 'good and bad' deaths in hospital.

AIM: This paper reports a study investigating hospital nurses' experiences of death and dying. BACKGROUND: Despite advances in medical science and health care, together with the push towards individualizing approaches to patient care in the developed world, significant variation in the care of dying patients still exists. The international issues relating to differing types of death reveal both its complexity and diversity, with evidence of 'good death' experiences largely focused on hospice experiences, and a lack of research on death in general hospitals. METHOD: In-depth interviews were conducted in 1999 with a convenience sample of 29 Registered Nurses in the United Kingdom based on their hospital death experiences. Semiotic analysis was used to identify the 'deep structures' that underlie and form part of cultural communication as a way of understanding how nurses made sense of death. Data interpretation was enhanced through the use of a typology of 'good and bad deaths'. FINDINGS: The findings suggest that different experiences of death are based on the extent to which nurses were able to exert control over the dying process. The management of death in hospital is a major source of conflict for nurses. Good and bad death experiences were constructed according to their impact on the sentimental order of the ward, the intangible, but real patterns of mood that influenced nurses' feelings. Moreover, good and bad deaths focused less on patients' needs and the dying process and more on the death event and nurses' abilities to manage organizational demands. CONCLUSION: There is a need to improve communication with patients and families about diagnosis and prognosis to ensure that effective communication takes place and 'blocking behaviour' is avoided. The findings also challenge practitioners to focus attention on death as a process, and to prioritize patients' needs above those of the organization. Moreover, there is the need for guidelines to be developed enabling patients to have a role in shaping events at the end of their lives.

Systematic review of prevalence of aspirin induced asthma and its implications for clinical practice.

OBJECTIVE: To reassess the prevalence of aspirin induced asthma and other issues related to the syndrome. DATA SOURCES: Biosis, SciSearch (1990 to March 2002), Embase (1974 to March 2002), Medline (1966 to March 2002), Toxline, Derwent Drug File (1964 to March 2002), Conference Papers Index and Inside Conferences, Int'l Pharmaceutical Abstracts, Pharma-Online (1978 to March 2002). SELECTION CRITERIA: Study type, patient population, and outcome measures. Review was restricted to respiratory responses to analgesics available without prescription. RESULTS: The prevalence of aspirin induced asthma was highest when determined by oral provocation testing (adults 21%, 95% confidence interval 14% to 29%; children 5%, 0% to 14%) than by verbal history (adults 3%, 2% to 4%; children 2%, 1% to 3%). Cross sensitivity to doses of over the counter non-steroidal anti-inflammatory drugs was present in most patients with aspirin induced asthma: ibuprofen, 98%; naproxen, 100%; and diclofenac, 93%. The incidence of cross sensitivity to paracetamol among such patients was only 7%. CONCLUSIONS: Aspirin induced asthma in adults is more prevalent than previously suggested. When there is a clinical necessity to use aspirin or a non-steroidal anti-inflammatory drug and there is uncertainty about safety, oral provocation testing should be performed.

An in vitro study into the corrosion of intra-oral magnets in the presence of dental amalgam.

The aim of this investigation was to study the corrosion behaviour and products of uncoated neodymium-iron-boron magnets in the presence of dental amalgam. Microcosm plaques were grown on discs of neodymium-iron-boron magnets or amalgam in a constant depth film fermentor. The biofilms were supplied with artificial saliva and growth was determined by viable counting. The results showed that the neodymium-iron-boron magnets corroded with an average daily weight loss of 0.115 +/- 0.032 per cent. However, when the magnets were in close proximity to the amalgam the amount of corrosion was reduced to a daily loss of 0.066 +/- 0.023 per cent. The highest loss of constituent elements from the corrosion products of the magnets was observed for iron. The composition of the microcosm plaques altered markedly between the two materials with less streptococci and more Veillonella spp. present in the biofilms grown on magnets in the presence of amalgam. The corrosion of neodymium-iron-boron magnets is limited and in the presence of amalgam is reduced further. This suggests that amalgam present in the mouth will not cause an increased clinical risk in terms of biocompatibility with neodymium-iron-boron magnets.

Macmillan cancer and palliative care specialists: their practice development support needs.

This study explores the practice development support needs of specialist nurses working in cancer and palliative care, in order to assist in the improvement of cancer and palliative care services. Using a whole population survey, postal questionnaires were sent to 1144 Macmillan post holders in England, Scotland and Wales. There was a 75.7% response rate. Three focus groups consisting of a total of 21 respondents were also used as a secondary form of data collection to supplement and expand upon the questionnaire responses. The findings reveal substantial practice development needs, particularly in relation to organizational support and guidance, education support, resources and access to evidence. The study demonstrates that nurses felt unable to engage in improving care unless initiatives were supported in practical ways by their organizations.

Nurses and health support workers' views on cardiopulmonary resuscitation in a hospice setting.

This paper reports on a study which took place in a 15-bed hospice and provides an account of the views of registered nurses (n = 12) and health support workers (n = 10) in relation to cardiopulmonary resuscitation (CPR) within a hospice setting. The study was part of a larger ethnographic research project being conducted in the hospice when the British Medical Association/Royal College of Nursing and the Resuscitation Council UK (Resuscitation Council UK, 2001) published guidelines urging all establishments that face decisions about attempting CPR to develop local policies. The guidelines provided the impetus for the present study, the aim of which was to explore staff responses to the introduction of a CPR policy in the hospice. Semi-structured interviews were conducted on a purposive sample of hospice staff. The findings raise issues about the implementation of CPR in a context where it was felt that the patient should be allowed to die a natural death.

Do Not Resuscitate orders and older patients: findings from an ethnographic study of hospital wards for older people.

BACKGROUND AND AIM: This paper reports on the findings from an ethnographic study involving three wards in two hospitals in the Northwest of England and focuses on the controversial issue of Do Not Resuscitate (DNR) orders. The study aimed to explore the way in which terminal care was provided to older patients and examined the way in which DNR orders were a socially constructed part of the practices of both nurses and doctors. METHOD: An ethnographic approach was adopted that used participant observation and semi-structured interviews with nurses and doctors. A purposive sample of 28 qualified nurses and five medical staff were interviewed. The decision-making process of DNR orders became the focus of the interview questions. FINDINGS: The findings reveal that DNR decision-making was largely socially constructed from the interactions of hospital staff. Patients were not asked their preference and were excluded from any decision-making about Cardiopulmonary Resuscitation (CPR) or DNR orders. Two major findings emerge. First, DNR orders and the non-use of CPR could be seen as a form of medical beneficence, resulting from the often described paternalistic attitudes of hospital doctors. Second, there was a clear indication that DNR orders and the non-use of CPR for certain patients was based on improving the quality of patients' lives. CONCLUSION: The study raises issues about the quality of care received by frail older patients whom the nurses felt would not survive a futile medical procedure. The conclusion considers the need for hospitals to formulate and implement CPR policies, particularly in the prevailing climate in which patients are encouraged to become active participants in their own health care.

Respiratory function in singleton and twin pregnancy.

OBJECTIVE: Singleton pregnancy causes important changes in respiratory function. The incidence of twin pregnancies is increasing, but it is not known whether affected women suffer greater respiratory compromise. The aim of this study was to determine if changes in respiratory function during pregnancy in healthy women were greater in those with a twin pregnancy compared with those with a singleton pregnancy. DESIGN: Cross sectional study. SETTING: London teaching hospital. POPULATION: Healthy pregnant women attending the antenatal clinic and ultrasound department. METHODS: A cross sectional study of respiratory function was performed in 68 women with twin pregnancies (17 examined in the first trimester, 35 second trimester, 16 third trimester) and 140 women with singleton pregnancies (28, 80, 40, respectively) and 22 non-pregnant women. Women were examined once between 7 and 40 weeks of gestation. Forced vital capacity, relaxed vital capacity, forced expiratory volume in 1 second (FEV1), peak flow, inspiratory capacity, functional residual capacity (FRC), expiratory reserve volume, pulmonary diffusing capacity and minute ventilation were measured. RESULTS: Both in twin and singleton pregnancies, the mean FRC and expiratory reserve ventilation of women studied in the third trimester and minute ventilation of women studied in each trimester differed significantly from that of the non-pregnant women. There were, however, no significant differences demonstrated in respiratory function between healthy women with twin as compared with singleton pregnancies. CONCLUSION: In healthy women, the extra demands of atwin compared with a singleton pregnancy do not compromise further the respiratory system.
