去年我写了一篇“如何防范和减少产科医疗错误”的文章[1],刊登在《中国实用妇科与产科杂志》2018年第1期上,编辑部同志告诉我读者对该文的反映还不错,鼓励我再写一篇有关减少产科医疗错误的文章。我想,再写的话,不免有“老调子重弹”之嫌,但编辑部的盛情难却,祇有从命,不当之处,还请读者见谅。  相似文献

The Emerging Infections Program (EIP) is a collaboration between the Centers for Disease Control and Prevention and 10 state health departments working with academic partners to conduct active population-based surveillance and special studies for several emerging infectious disease issues determined to need special attention. The Centers for Disease Control and Prevention funds the 10 EIP sites through cooperative agreements. Our objective was to highlight 1) what being an EIP site has meant for participating health departments and associated academic centers, including accomplishments and challenges, and 2) the synergy between the state and federal levels that has resulted from the collaborative relationship. Sharing these experiences should provide constructive insight to other public health programs and other countries contemplating a collaborative federal–local approach to collective public health challenges.  相似文献

目的:了解山东省三甲医院医护人员院感暴发应急能力,分析其影响因素,为提升医护人员院感暴发应急能力提供参考依据。方法:采用多阶段分层随机抽样的方法,对抽取的三甲医院的医护人员进行调查。用统计软件SPSS17.0对资料进行分析处理,单因素分析运用χ~2检验,运用Logistic回归分析方法进行多因素分析。结果:多因素分析结果显示,三甲医院医护人员院感暴发应急能力的影响因素为:年龄、心理健康状况、是否知晓院感暴发与院感聚焦区别、院感暴发应急知识了解程度、院感暴发应急隔离措施了解程度、培训教育6个因素。结论:部分医护人员院感暴发应急能力欠缺,医院应采取定期对医护人员进行心理疏导、定期进行教育培训等措施,提高医护人员院感暴发应急能力,以有效控制院感暴发事件,减少人员伤亡。  相似文献

There is increasingly a call for clinical relevance in the teaching of biomedical sciences within all health care courses. However, this presupposes that there is a clear understanding of what can be considered core material within the curricula. To date, the anatomical sciences have been relatively poorly served by the development of core syllabuses, particularly for specialized core syllabuses such as neuroanatomy. One of the aims of the International Federation of Associations of Anatomists (IFAA) and of the European Federation for Experimental Morphology (EFEM) is to formulate, on an international scale, core syllabuses for all branches of the anatomical sciences using Delphi Panels consisting of anatomists, scientists, and clinicians to initially evaluate syllabus content. In this article, the findings of a Delphi Panel for neuroanatomy are provided. These findings will subsequently be published on the IFAA website to enable anatomical (and other cognate learned) societies and individual anatomists, clinicians, and students to freely comment upon, and elaborate and amend, the syllabuses. The aim is to set internationally recognized standards and thus to provide guidelines concerning neuroanatomical knowledge when engaged in course development. Clin.

ObjectiveTo report changes in pediatric clerkship nighttime clinical structures before and after implementation of the 2011 Accreditation Council for Graduate Medical Education (ACGME) resident duty hour standards.MethodsAs part of the 2011 Council on Medical Student Education in Pediatrics (COMSEP) member annual survey, we surveyed leaders of pediatric undergraduate medical education on their medical school's current nighttime clinical structure, changes in nighttime structure between 2010 and 2011, and their school's student duty hour standards.ResultsFifty-six percent (n = 83) of Liaison Committee for Medical Education (LCME)-accredited medical schools responded to the survey. Of received responses, 98% of pediatric clerkships have some form of nighttime clinical experience; 49% of clerkships have medical students stay late, 24% of clerkships utilize night shifts, and 16% use a traditional call structure. Forty-five percent of clerkships report changing their nighttime clinical experience after implementation of the 2011 ACGME duty hour standards; 46% of clerkships that changed had previously used traditional call. Seventy-six percent of clerkships report having medical student duty hour standards at their medical school.ConclusionsThe majority of pediatric clerkships in our survey include nighttime clinical experiences in their curriculum, although variability exists in the type of structure. Additionally, the new ACGME duty hour standards appear to affect clerkships directors' choice of structure.  相似文献
