Training in and assessment of the procedural skills required to perform peripheral nerve blockade

The training and ongoing education of medical practitioners has undergone major changes in an incremental fashion over the past 15 years. These changes have been driven by patient safety, educational, economic and legislative/regulatory factors. In the near future, training in procedural skills will undergo a paradigm shift to proficiency based progression with associated requirements for competence-based programmes, valid, reliable assessment tools and simulation technology. Before training begins, the learning outcomes require clear definition; any form of assessment applied should include measurement of these outcomes. Currently training in a procedural skill often takes place on an ad hoc basis. The number of attempts necessary to attain a defined degree of proficiency varies from procedure to procedure. Convincing evidence exists that simulation training helps trainees to acquire skills more efficiently rather than relying on opportunities in their clinical practice. Simulation provides a safe, stress free environment for trainees for skill acquisition, generalization and transfer via deliberate practice. The work described in this thesis contributes to a greater understanding of how medical procedures can be performed more safely and effectively through education. The effect of feedback, provided to novices in a standardized setting on a bench model, based on knowledge of performance was associated with an increase in the speed of skill acquisition and a decrease in error rate during initial learning. The timing of feedback was also associated with effective learning of skill. A marked attrition of skills (independent of the type of feedback provided) was demonstrable 24 hrs after they have first been learned. Using the principles of feedback as described above, when studying the effect of an intense training program on novices of varied years of experience in anaesthesia (i.e. the present training programmes / courses of an intense training day for one or more procedures). There was a marked attrition of skill at 24 hours with a significant correlation with increasing years of experience; there also appeared to be an inverse relationship between years of experience in anaesthesia and performance. The greater the number of years of practice experience, the longer it required a learner to acquire a new skill. The findings of the studies described in this thesis may have important implications for the trainers, trainees and training bodies in the design and implementation of training courses and the formats of delivery of changing curricula. Both curricula and training modalities will need to take account of characteristics of individual learners and the dynamic nature of procedural healthcare.

Professional perspectives on decision making about the long-term care of older people

With the increasing pressure on social and health care resources, professionals have to be more explicit in their decision making regarding the long-term care of older people. This grounded theory study used 19 focus groups and nine semi-structured interviews (99 staff in total) to explore professional perspectives on this decision making. Focus group participants and interviewees comprised care managers, social workers, consultant geriatricians, general medical practitioners, community nurses, home care managers, occupational therapists and hospital discharge support staff. The emerging themes spanned context, clients, families and services. Decisions were often prompted by a crisis, hindering professionals seeking to make a measured assessment. Fear of burglary and assault, and the willingness and availability of family to help were major factors in decisions about living at home. Service availability in terms of public funding for community care, the availability of home care workers and workload pressures on primary care services influenced decision 'thresholds' regarding admission to institutional care. Assessment tools designed to assist decision making about the long-term care of older people need to take into account the critical aspects of individual fears and motivation, family support and the availability of publicly funded services as well as functional and medical needs.

Refractory cachexia and truth-telling about terminal prognosis; A qualitative study

The purpose of this paper is to examine the consequences that medical practitioners’ decisions about whether or not to be candid about terminal prognosis have for those suffering from refractory cachexia and their families. It presents the findings of a qualitative study which used focus groups and semi-structured interviews of a volunteer sample of doctors, nurses and dieticians in a cancer centre of a large teaching hospital in Northern Ireland. Respondents reported that some physicians tended to avoid discussing terminal prognosis in a direct manner with their patients. Nurses and dieticians tended to be reluctant to engage in conversations about weight loss with patients with cachexia. One of the reasons they reported for their lack of acknowledgement of weight loss concerned the close association between refractory cachexia and terminal prognosis. Because they viewed the telling of bad news as an exclusive prerogative of medical practitioners, they did not feel in a position to discuss cachexia because they were concerned that this had the potential to raise end-of-life issues that lay outside the boundaries of their professional role. This meant patients and their families were provided with little information about how to cope with the distressing consequences of cachexia.

Blood eosinophils as a marker of likely corticosteroid response in children with preschool wheeze: time for an eosinophil guided clinical trial?

Childhood wheezing is common particularly in children under the age of six years and in this age-group is generally referred to as preschool wheezing. Particular diagnostic and treatment uncertainties exist in these young children due to the difficulty in obtaining objective evidence of reversible airways narrowing and inflammation. A diagnosis of asthma depends on the presence of relevant clinical signs and symptoms and the demonstration of reversible airways narrowing on lung function testing, which is difficult to perform in young children. Few treatments are available and inhaled corticosteroids are the recommended preventer treatment in most international asthma guidelines. There is however considerable controversy about its effectiveness in children with preschool wheeze and a corticosteroid responder phenotype has not been established. These diagnostic and treatment uncertainties in conjunction with the knowledge of corticosteroid side-effects, in particular the reduction of growth velocity, has resulted in a variable approach to inhaled corticosteroid prescribing by medical practitioners and a reluctance in carers to regularly administer the treatment. Identifying children who are likely responders to corticosteroid therapy would be a major benefit in the management of this condition. Eosinophils have emerged as a promising biomarker of corticosteroid responsive airways disease and evaluation of this biomarker in sputum has successfully been employed to direct management in adults with asthma. Obtaining sputum from young children is time-consuming and difficult and it is hard to justify more invasive procedures such as a bronchoscopy in young children routinely. Recently, in children, interest has shifted to assessing the value of less invasive biomarkers of likely corticosteroid response and the biomarker 'blood eosinophils' has emerged as an attractive candidate. The aim of this review is to summarise the evidence for blood eosinophils as a predictive biomarker for corticosteroid responsive disease with a particular focus on the difficult area of preschool wheeze. 

How women use and experience western herbal practice for distress: implications for health care and self-management approaches.

Introduction: In the UK, common mental health disorders account for one in five of all work days lost, and cost employers £25bn each year. Herbal medicine has been shown to potentially be of use for mental distress, including conditions like anxiety. In 2008, 35% of British adults surveyed claimed to have used herbal medicine at some stage, the majority of whom were women. However, there is little research into how the users of western herbal medicine (WHM) experience the practice of herbal medicine, or how these experiences may change over time. Our research is studying women in the south-east of the UK who are suffering from distress (either as a primary complaint, or associated with another condition) who are seeking the services of a herbalist who practices WHM. Aim: To investigate the experiences of western herbal practice by women who are suffering with distress. Methods: The study is using semi-structured interviews of around thirty women, to elicit patient narratives at two time points. Thematic analysis is being used to consider how distressed women perceive and experience their distress, their reasons for using WHM, what contribution the women perceive the consultation and treatment with WHM may or may not make to their wellbeing, and whether their experiences change over time. Currently, sixteen women have been interviewed, and a preliminary thematic analysis has commenced. Results: Preliminary finding suggest that not only do women internalise their distress, but that they are surprisingly isolated in how they deal with it, whilst some also express social embarrassment about their experiences. The women perceived that their distress is not always considered seriously from their medical practitioners’ point of view. These women are drawn to herbalists not only in a search for effective treatment, but also to be given time to have their story heard, to form a collaborative relationship, and to attempt to regain some control of their life. The herbal treatment is valued due to its perceived naturalness, and reduced risk of adverse side effects. Nevertheless, WHM is just one of a number of self-care strategies that women utilise to help manage their distress. Discussion: Effective treatment is not only dependent upon the herbs, but also upon an effective therapeutic relationship. Feeling that the herbalist hears their story, provides a treatment plan that is individually tailored to the patient, and is available (even outside of the consultation) are all important in helping to establish this relationship.

La médecine indigène comme instrument normatif social: l’exemple du corps malade navajo

La médecine traditionnelle indigène peut parfois se poser comme un instrument normatif désignant le malade comme celui qui transgresse l‘ordre établi par les ancêtres sacrés et permet à la maladie d‘advenir. Un tiers malveillant ou un sorcier peuvent également être les causes du désordre physiologique et moral du corps social communautaire. L‘étiologie navajo repose sur deux phénomènes : l‘existence de sociosomas (troubles liés à une mauvaise relation à l‘entourage) et de mouvements d‘exclusion ou d‘inclusion du corps étranger, de la conduite déviante. L‘étude de la figure du malade dans les mythes soulignera l‘aspect normatif des thérapeutiques navajo. Enfin, une réflexion sur la justification idéologique de l‘intégration des pratiques ancestrales au protocole de soin montrera dans quelle mesure la collaboration entre praticiens traditionnels et personnels de santé contribue à stigmatiser le malade comme l‘épitome de toutes les déviances : par rapport à la tradition mais aussi au modèle social dominant.

Dr John Snow and an early investigation of groundwater contamination

John Snow was a physician but his studies of the way in which cholera is spread have long attracted the interest of hydrogeologists. From his investigation into the epidemiology of the cholera outbreak around the well in Broad Street, London, in 1854, Snow gained valuable evidence that cholera is spread by contamination of drinking water. Subsequent research by others showed that the well was contaminated by sewage. The study therefore represents one of the first, if not the first, study of an incident of groundwater contamination in Britain. Although he had no formal geological training, it is clear that Snow had a much better understanding of groundwater than many modern medical practitioners. At the time of the outbreak Snow was continuing his practice as a physician and anaesthetist. His casebooks for 1854 do not even mention cholera. Yet, nearly 150 years later, he is as well known for his work on cholera as for his pioneering work on anaesthesia, and his discoveries are still the subject of controversy.

Immersive open surgery simulation

Realistic medical simulation has great potential for augmenting or complimenting traditional medical training or surgery planning, and Virtual Reality (VR) is a key enabling technology for delivering this goal. Although, medical simulators are now widely used in medical institutions, the majority of them are still reliant on desktop monitor displays, and many are restricted in their modelling capability to minimally invasive or endoscopic surgery scenarios. Whilst useful, such models lack the realism and interaction of the operating theatre. In this paper, we describe how we are advancing the technology by simulating open surgery procedures in an Immersive Projection Display CAVE environment thereby enabling medical practitioners to interact with their virtual patients in a more realistic manner.

Community Care in Australia

Access and equity are guiding principles for community care in Australia. Community care in Australia is universally provided through Australia's Medicare system, which assures all people access to needed services. The largest community care system, the Home and Community Care Program (HACC), serves frail older and disabled people. The HACC program is undergoing steady reform to provide more seamless transitions of care for people from home care to residential care whether permanent or for respite purposes. Community health services provide a wide range of center-based and outreach services that any person may access and that are provided on the basis of need. Nevertheless, pressures for greater privatization of services cause tensions, and access is jeopardized further by shortages, particularly in rural areas, of aged care nurses, allied health personnel, and medical practitioners.

Hospital in the home: constructions of the nursing role - a literature review

• Acute medical and nursing treatment in the home is increasingly seen as an alternative to hospitalization. Models such as hospital in the home (HITH) or acute home care are said to provide a safe, comfortable environment for patients that is conducive to healing.

• A review of the literature reveals the embryonic nature of the research and discussion related to this alternative care delivery model. In general, the benefits of hospital in the home programmes are presented in an uncritical manner.

• Medical practitioners have embraced the move to home care as a means of expanding the use of advanced technologies and improved drug regimes beyond the hospital walls.

• The nursing response has been mechanistic and recipe-like while advancing the HITH nursing role as an opportunity for speciality practice by virtue of the increased autonomy and independence required.

• This review demonstrates the influence of a professional mandate for specialization, and the ideological and scientific interests that have influenced the role of the nurse.

The transition from pediatric to adult health care services for young adults with a disability : an ethical perspective

Young children with disabilities and their carers or parents tend to form a long-term dependent relationship with a paediatrician throughout childhood At some stage when the young person with a disability reaches early adulthood, the relationship is severed This paper draws upon recent research undertaken by the authors that describes the difficulties experienced by young people with disabilities as they go through the transition from paediatric care to adult mainstream health care services. The purpose of this article is to present the argument that the dependent, paternalistic relationship that tends to exist between young people with disabilities (and/or their carers) and paediatricians throughout childhood does not facilitate the successful negotiation of adult mainstream health care services, nor optimally promote the well-being of these young people with disabilities. It is proposed that the promotion of autonomy (or self-determination) via a well planned transition program will increase the likelihood that young adults with disabilities and/or their carers will be empowered to successfully negotiate the current mainstream health care system in Australia, and will enhance the well-being of young adults with disabilities.

The limits of medicine and the social consequences for sufferers of chronic fatigue syndrome

Chronic fatigue syndrome (CFS) appears to be made up of several clusters of illness categories acting alone or in tandem to cause the decline of health through; fatigue/exhaustion, sensitivity/allergies, pain, general muscle and joint pains, cognitive impairment and gastrointestinal problems. This study investigated how patients interpret, evaluate and respond to the complex and varied symptoms of chronic fatigue syndrome. Data were collected from persons with CFS using a survey (n=90) and an interview (n=45). The researchers investigated how chronic fatigue syndrome is diagnosed by medical practitioners, how the label of CFS is determined and the social consequences for the patient. The results confirm the limited ability of the biomedical paradigm to diagnose adequately and treat effectively 'socially constructed' and medically ambiguous illnesses like CFS. In the absence of a legitimated regime of medical treatment for CFS, a range of often expensive treatments are employed by CFS sufferers, from formal use of pharmaceutical drugs through to 'alternative' therapies, including herbal, vitamin, homeopathic, esoteric meditative techniques, spiritual healing and general counselling are taken in no particular order.

Potential of telemedicine : a preliminary evaluation through the innovation diffusion lens

With the rapid diffusion of innovative technologies in the healthcare industry, the potential of telemedicine has increasingly come into focus. Touted as a catalyst for an equitable healthcare framework among nations, research is wide and one spotlight is on the potential of this innovation to diffuse among the wider society. In this paper, we attempt a preliminary evaluation of the potential of telemedicine through the components of [Diffusion of Innovations (4th ed.). NY: The Free Press] diffusion of innovations theoretical lens, drawing also as relevant from reported literature. We expect that this preliminary evaluation will facilitate further academic research and make other stakeholders, such as regulators, medical practitioners, telecommunication providers and vendors, aware of potential steps to be taken to leverage telemedicine diffusion.

Health professionals' attitudes toward caring for people with hepatitis C

An estimated 170 million people worldwide have hepatitis C, which is a significant cause of morbidity and mortality. Therefore, health professionals (HPs) are likely to care for people with hepatitis C at some stage in their careers. However, little is known about HPs' attitudes towards treating people with hepatitis C. An analytical, cross-sectional survey was conducted to explore the inter-relationship among HPs' hepatitis C knowledge and attitudes towards treating people with hepatitis C and their self-reported clinical behaviour: Self-administered questionnaires were distributed to 3675 complementary therapists, dentists, medical practitioners, nurses, pharmacists, undergraduate medical and nursing students and people with hepatitis C in Victoria, Australia. Forty-six per cent responded (n = 1510). Only HP (complementary therapists, dentists, medical practitioners, nurses and pharmacists) data is presented (n = 1347).

Most HPs demonstrated adequate hepatitis C knowledge, but some displayed intolerant attitudes toward people with hepatitis C. Their self-reported compliance with infection control practices indicated that they frequently treated people with hepatitis C differently from other patients by using additional infection control precautions while treating patients with hepatitis C. In addition, fear of contagion and disapproval of injecting drug use emerged as barriers to their willingness to treat people with hepatitis C.

The results suggest that focusing education strategies on changing HPs' attitudes toward people with hepatitis C, injecting drug users, and infection control guidelines rather than concentrating solely on medical information might ultimately improve patient care.

Managing complex medication regimens: perspectives of consumers with osteoarthritis and healthcare professionals

BACKGROUND: Managing medications is complex, particularly for consumers with multiple coexisting conditions for whom benefits and adverse effects are unpredictable and health priorities may be variable.

OBJECTIVE: To investigate perceptions of and experiences with managing drug regimens from the perspectives of consumers with osteoarthritis and coexisting chronic conditions and of healthcare professionals from diverse backgrounds.

METHODS: Using an exploratory research design, focus groups were formed with 34 consumers and 19 healthcare professionals. Individual interviews were undertaken with 3 community medical practitioners.

RESULTS: Consumers' management of medications was explored in terms of 3 themes: administration of medications, provision of information, and the perceived role of healthcare professionals. In general, consumers lacked understanding regarding the reason that they were prescribed certain medications. Since all consumer participants had at least 2 chronic conditions, they were taking many drugs to relieve undesirable symptoms. Some consumers were unable to achieve improved pain relief and were reluctant to take analgesics prescribed on an as - needed basis. Healthcare professionals discussed the importance of using non-pharmacologic measures to improve symptoms; however, consumers stated that physicians encourage them to continue using medications, often for prolonged periods, even when these agents are not helpful.

CONCLUSIONS: Consumers were dissatisfied about the complexity of their medication regimens and also lacked understanding as to how to take their drugs effectively. Dedicated time should be devoted during medical consultations to facilitate verbal exchange of information about medications. Pharmacists must communicate regularly with physicians about consumers' medication needs to help preempt any problems that may arise. Instructions need to be revised through collaboration between physicians and pharmacists so that "as needed" directions provide more explicit advice about when and how to use such drugs. Future research, using large, generalizable samples, should examine trends related to consumers' experiences of symptomatic relief from chronic conditions and their understandings about medications.
