AimTo consolidate the evidence around the experiences of nursing undergraduates and faculty members navigating through remote and online education during the COVID-19 pandemic.BackgroundThe Coronavirus disease 2019 caused by the SARS-CoV-2 Virus (COVID-19) has placed massive pressure on healthcare, economic and education systems globally. Restrictive social distancing policies and public health measures necessitated educational institutions to switch from face-to-face to remote and online education to sustain the learning process. These changes have created an uncertain path and undue stress for healthcare learners and faculty, especially for professional roles that traditionally require more hands-on and access to clinical practice particularly pre-licensure nursing students. As such, there is an urgent need to consolidate evidence on the experiences of nursing undergraduates and faculty members as they navigate the rapid transition from face-to-face to remote and online education to ensure continuity of learning in achieving optimal learning outcomes and to support them during current and future public health crises.DesignA systematic review and meta-synthesis of the qualitative literature was undertaken using Sandelowski and Barroso’s approach.MethodsSix electronic databases, CINAHL, Embase, ERIC, PsycINFO, PubMed and Scopus, were searched systematically using the eligibility criteria from December 2019 to September 2022. The Critical Appraisal Skills Program checklist for qualitative studies was used to conduct the critical appraisal of the selected articles.ResultsForty-seven studies were included in this review, which encapsulates the experiences of 3052 undergraduates and 241 faculty members. An overarching meta-theme ‘Remote and online education: a rollercoaster ride’, emerged along with three main meta-themes: (1) Transition to remote and online education: A turbulent road, (2) Acceptance of the untravelled road, (3) Hopes and recommendations for the road ahead.ConclusionTo improve nursing undergraduates’ and faculty member’s navigation of remote and online education, more institutions should move towards establishing hybrid education as the new ‘normal’ and exercise prudence in the organisation and delivery of curriculum, teaching, well-being and clinical attachment contingencies of their healthcare courses.  相似文献

临床医学专业研究生课程体系是培养研究生过程中极为重要的环节,课程是实现教育教学目标的关键载体和平台。目前,我国对于临床医学教育提出了创新改革课程体系的具体要求。2019年我国教育部发布了《教育部卫生部关于加强医学教育工作提高医学教育质量的若干意见》,表示各大医学高校要“积极全面开展课程体系革新,使得医学知识与自然科学和人文科学知识的融合”。突出学生的教学主体性,创建学生为中心的专业教学模式,大力促进教学方法的创新和实践,强化学生综合知识能力、创新意识以及批判性思维的培养和锻炼。本文对基于核心能力的临床医学专业研究生课程体系建设进行研究,并提出具体的建设策略,以期为我国临床医学专业研究生培养提供有价值的参考建议。  相似文献

随着国内高等医学教育管理体制改革的日益深化和素质教育的全面推进,医学院校的教学实验室建设从以往单一学科设置、传统的基础医学教学实验室逐步演变为按功能分类、按学科群布局的基础医学实验教学中心。在陆军军医大学基础医学实验教学中心建设过程中,从构建“大中心”、创建实验教学课程新体系、探索创新实践教育新模式、创建优秀实验教师队伍等方面进行了实践探索,相关工作为今后实验教学中心的建设提供了实践参考。  相似文献

ObjectiveWe conducted a realist review to understand how (mechanism) and in what circumstances (context) evidence-based practices are sustained in rehabilitation (outcome).Data SourcesMEDLINE, Embase, reference lists, and targeted websites.Study SelectionTwo independent reviewers calibrated study selection; then 1 reviewer screened all titles and abstracts, while the second reviewer screened a random 20%. We repeated this process for full texts. We included 115 documents representing 61 implementation projects (8.9% of identified documents). Included documents described implementation projects in which physical therapists, occupational therapists, and/or speech-language pathologists were the target users of an evidence-based practice.Data ExtractionTwo reviewers repeated the independent process described in study selection to extract basic study and sustainability characteristics as well as context, mechanism, outcome, and strategy text.Data SynthesisUsing basic numerical analyses, we found that only 54% of evidence-based practices in rehabilitation are sustained. Furthermore, while authors who reported sustainability planning sustained the practice 94% of the time, sustainability planning in rehabilitation is rare (only reported 26% of the time). Extracted text was synthesized using the realist technique of inductive and deductive retroduction in which context, mechanism, outcome, and strategy text are combined into narrative explanations of how sustainability works. To inform these explanations, we applied normalization process theory and the theory of planned behavior. Collectively, the 52 identified narratives provide evidence for 3 patterns: (1) implementation and sustainability phases are interconnected, (2) continued use of the evidence-based practice can be interpreted as the ultimate sustainability outcome, and (3) intermediate sustainability outcomes (ie, fit/alignment, financial support, benefits, expertise) can become contextual features influencing other sustainability outcomes.ConclusionsImplementation teams can use the narrative explanations generated in this review to optimize sustainability planning. This can sustain practice changes and improve quality of care and patient outcomes. Future research should seek to iteratively refine the proposed narrative explanations.  相似文献

Despite health care reform, our nation continues to struggle containing health care costs while meeting the needs of persons with behavioral health disorders and comorbid chronic care conditions. The purpose of this article is to propose that dually certified primary care and psychiatric mental health nurse practitioners may be the disruptive innovation that becomes the solution for improving the coordination and care for high-need patients while containing costs. The concepts of disruptive innovation, integrated care, and whole person care are discussed followed by an introduction to the innovative primary care and psychiatric mental health nurse practitioner’s role and its potential for health care system disruption. Finally, a call to nursing is proffered to seize current opportunities to meet the Triple Aim challenge by providing whole person care that is high-quality, cost-effective, and satisfactory to patients because it is truly patient centered and meets their needs.  相似文献

Background

Robotic surgery is increasingly adopted into surgical practice, but it remains unclear what level of robotic training general surgery residents receive. The purpose of our study was to assess the variation in robotic surgery training amongst general surgery residency programs in the United States.

Methods

A web-based survey was sent to 277 general surgery residency programs to determine characteristics of resident experience and training in robotic surgery.

Results

A total of 114 (41%) programs responded. 92% (n?=?105) have residents participating in robotic surgeries; 68%(n?=?71) of which have a robotics curriculum, 44%(n?=?46) track residents’ robotic experience, and 55%(n?=?58) offer formal recognition of training completion. Responses from university-affiliated (n?=?83) and independent (n?=?31) programs were not significantly different.

Conclusions

Many general surgery residencies offer robotic surgery experience, but vary widely in requisite components, formal credentialing, and case tracking. There is a need to adopt a standardized training curriculum and document resident competency.  相似文献
