Fibroepithelial polyps (FEPs) are common, benign intraoral lesions that tend to develop slowly at predictable sites, often in response to local irritation or trauma. Historical precedent often results in referral to oral and maxillofacial surgery (OMFS) departments for biopsy, often irrespective of symptoms, and histological assessment. OMFS and pathology services are struggling to cope with an increasing workload that will potentially lead to widespread delays to diagnosis and treatment. Over the past 20 years, clinical pathways and guidance have been developed to ensure that healthcare interventions, such as the removal of third molars, tonsils, skin tags, and benign moles, are evidence-based, have a net patient benefit, and ensure the best use of finite NHS resources. However, no such guidance exists for intraoral lesions and we regard this as an oversight. We analysed the removal of 682 FEPs over a seven-year period and report sensitivities of 92.4% for a “confirmed clinical suspicion of an FEP” and 99.7% for a “confirmed clinical suspicion of a benign diagnosis”. The incidence of non-benign disease was 0.3%. Primary care dentists should be able to diagnose and monitor FEPs and refer only if symptoms are serious or in high-risk patients or sites. Adopting this practice across the UK could free up to 1825 four-hour OMFS clinics, 405 hours of consultant histopathologists’ time, and recurring savings to the NHS estimated to be in the region of £620 000/annum. We believe that the removal of FEPs should be reclassified as an “intervention not normally funded”, and the time and resources put to better use treating patients with lesions of questionable pathology.  相似文献

Worldwide, researchers routinely study children indirectly through adults who act as proxies for such children. The call for researchers to rather study children directly and adopt less intrusive child-friendly methodologies has become louder. The draw-and-write technique is regarded as a less intrusive child-friendly method of collecting data that can be used for this purpose. This paper reports the findings of a qualitative study that sought to establish the feasibility of the draw-and-write technique in exploring the resilience of children orphaned by AIDS. This study involved a convenience sample of 23 IsiXhosa-speaking orphaned children aged from 13 to 17. The participants were in grades 6 to 10 and they resided in two child and youth care centres in the Eastern Cape province of South Africa. As part of the draw-and-write technique the participants were asked to make drawings of what enabled them to cope with their lives and to write short narratives in which they explained their drawings. Inductive content analysis was used to analyse the data and this process yielded two main themes, namely: personal protective resources and socio-ecological protective resources. The findings show that complex combinations of personal and socio-ecological resilience resources enabled the resilience of the orphaned children. The findings challenge researchers not to be oblivious to alternative child-friendly methods of research such as the draw-and-write technique when young people are the unit of analysis. The findings of this study have implications for research as well as practice in the field of education and psychology.  相似文献

重视医学信用伦理的研究与开发   总被引:7,自引:3,他引:4  
医疗行业市场化是必然趋势。在医疗行业市场化进程中,医学伦理道德除了道德价值之外,还含有积极的经济内涵。医学伦理道德也是重要的医疗资源,通过参与医疗市场资源的配制和运作,也可以产生经济效益,转化为医疗资本。医疗行业要重视医学伦理道德资源的开发。信用伦理是在市场经济条件下形成的,这是医学伦理学所面临的新课题。笔者认为,不说谎、不期诈,兑现承诺,保证医疗质量,发扬医学人道主义,是医学信用伦理的四项基本标准。  相似文献

Objectives. To describe nurse migration patterns in the Philippines and their benefits and costs.
Principal Findings. The Philippines is a job-scarce environment and, even for those with jobs in the health care sector, poor working conditions often motivate nurses to seek employment overseas. The country has also become dependent on labor migration to ease the tight domestic labor market. National opinion has generally focused on the improved quality of life for individual migrants and their families, and on the benefits of remittances to the nation. However, a shortage of highly skilled nurses and the massive retraining of physicians to become nurses elsewhere has created severe problems for the Filipino health system, including the closure of many hospitals. As a result, policy makers are debating the need for new policies to manage migration such that benefits are also returned to the educational institutions and hospitals that are producing the emigrant nurses.
Conclusions and Recommendations. There is new interest in the Philippines in identifying ways to mitigate the costs to the health system of nurse emigration. Many of the policy options being debated involve collaboration with those countries recruiting Filipino nurses. Bilateral agreements are essential for managing migration in such a way that both sending and receiving countries derive benefit from the exchange.  相似文献

The effectiveness of organizational interventions in reducing the adverse consequences of work–family conflict has produced mixed findings. This paper examines the relationship between the use of organizational ‘family friendly’ resources (such as crèche facilities, flexible working hours, and job sharing), with levels of work–family conflict, and job and family satisfaction over time. Using structural equation modelling, these associations were tested in 398 employed men and women who each completed a self‐report questionnaire administered on two occasions. The use of organizational interventions directly predicted increased levels of concurrent (Time 1) work–family interference and increased levels of subsequent (Time 2) job satisfaction. Both organizational interventions and family interventions (i.e. support) positively predicted subsequent family satisfaction. The research demonstrates that the provision of organizational ‘family‐friendly’ practices will produce improved psychological outcomes for employees.
