AimThe purpose of this integrative review is to provide a comprehensive review of ethical considerations for host communities and nursing programs in planning, implementing and evaluating global health experiences for nursing students.BackgroundGlobal health experiences for nursing students are proliferating rapidly across university settings while at the same time decreasing the average time spent in the host country engaged with local communities. Global health experiences are an area where students can experience ethics as it is applied across varied contexts including resource limited international settings. As nursing education expands its global programming, exploring the ethical implications of designing, implementing and evaluating GHEs becomes pivotal to build respectful, sustainable relationships with global partners and best prepare nursing students for ethical professional practice in an interconnected world.DesignWe conducted an integrative review to examine ethical considerations in development of ethical global health experiences that benefit, rather than harm, host communities and participating nursing student guests.MethodsThe search included articles published in English language, peer-reviewed journals between 1998 and 2021 that discussed ethics in the context of nursing students traveling internationally for global health experiences. Eighteen articles met criteria for review.ResultsOverall, findings demonstrate relatively little research specific to ethical engagement in global health experiences. The articles in this integrative review discussed a range of ethical attributes including reciprocity or collaboration, respect, sustainability or commitment, justice and openness. Recommendations based on research and non-research articles are provided.ConclusionsEthical comportment in global health experiences requires careful planning, implementation and evaluation to assure an equitable and sustainable partnership between host community, faculty and nursing student guests.  相似文献

Low- and middle-income countries (LMICs) bear the greatest burden of cardiovascular disease (CVD) worldwide. Emerging evidence, mostly from industrialized countries, suggest that neighborhood characteristics influence cardiovascular health. This study presents results from 27,797 participants living in six LMICs on the association of perceived neighborhood social cohesion, the degree of connectedness among neighbors, with 10-year risk of CVD. We observed that greater perceived neighborhood social cohesion was associated with lower odds of high (>20%) 10-year CVD risk (OR = 0.67, 95%CI: 0.53–0.86). These novel findings, suggest that interventions to enhance social cohesion may have beneficial effects on cardiovascular health in LMICs.  相似文献

The rapid development of innovations and new technologies, the focus on the life-course approach to immunization and equity, and the prevalent hesitancy towards vaccines requires immunization staff to be well-trained and updated regularly in order to deliver quality immunization services to the public. The need for advanced vaccinology training is therefore paramount. In preparation for a second Global Workshop on Advanced Vaccinology Training that took place in March 2022, this paper presents the results of a survey aiming to provide a thorough update of a landscape analysis on advanced vaccinology courses conducted in 2018 and a look at the impact of the COVID-19 crisis. Thirty-three course organizers responded to a survey to provide information on their respective course. Of those, 17 courses are short courses, 11 post-graduate courses and 5 are Master level courses. Most courses are organized on an annual basis. Even though some courses were not sustained overtime, the number of courses has been increasing during the last few years, and at least one vaccinology course is now being offered in each WHO region. Although the training capacity has increased tremendously, the need still exceeds the capacity and many courses have way more applicants than they can select. The most frequent challenges reported included sustainable funding and identifying faculty. The COVID-19 pandemic impacted the delivery of several vaccinology courses, which have been postponed or reformatted to an online or hybrid training event. An e-portal of the global collaboration has been established to facilitate communication between the different courses and to assist future course participants to identify the most suitable course for their needs.  相似文献

The emerging field of global oral and maxillofacial surgery (OMS) aims to improve worldwide access to safe, timely, and affordable OMS care. However, there exists a dearth of literature thoroughly detailing the scope of academic global OMS collaborations between high-income countries (HICs) and low- and/or lower middle-income countries (LICs/LMICs). This scoping review was performed to characterize the landscape of global academic OMS collaborations between HICs and LICs/LMICs. A five-stage methodological framework was used. Academic global OMS collaborations from 1996 to 2020 were identified via an electronic database and grey literature review. A total 1318 articles were identified on December 17, 2020. Following the application of inclusion and exclusion criteria, 71 articles describing 81 unique global OMS academic collaborations were included in the final analysis. The most common HIC was the United States (44.4%); the majority of LIC/LMICs were within Africa (45.8%). Of the total interventions, 89.6% improved LIC/LMIC capacity development, and surgical (43.8%) interventions were the most common. By serving as a central report on current and past academic collaborations in global OMS, this review helps identify areas in need of surgical capacity building, lays the foundation for future research efforts on the topic, and serves as a resource for individuals aiming to become involved in global OMS.  相似文献

In this paper, we argue that understanding and addressing the problem of poor-quality medical products requires a more interdisciplinary approach than has been evident to date. While prospective studies based on rigorous standardized methodologies are the gold standard for measuring the prevalence of poor-quality medical products and understanding their distribution nationally and internationally, they should be complemented by social science research to unpack the complex set of social, economic, and governance factors that underlie these patterns. In the following sections, we discuss specific examples of prospective quality surveys and of social science studies, highlighting the value of cross-sector partnerships in driving high-quality, policy-relevant research in this area.  相似文献
