S. M. White C. L. Shelton A. W. Gelb C. Lawson F. McGain J. Muret J. D. Sherman representing the World Federation of Societies of Anaesthesiologists Global Working Group on Environmental Sustainability in Anaesthesia 《Anaesthesia》2022,77(2):201-212
The Earth’s mean surface temperature is already approximately 1.1°C higher than pre-industrial levels. Exceeding a mean 1.5°C rise by 2050 will make global adaptation to the consequences of climate change less possible. To protect public health, anaesthesia providers need to reduce the contribution their practice makes to global warming. We convened a Working Group of 45 anaesthesia providers with a recognised interest in sustainability, and used a three-stage modified Delphi consensus process to agree on principles of environmentally sustainable anaesthesia that are achievable worldwide. The Working Group agreed on the following three important underlying statements: patient safety should not be compromised by sustainable anaesthetic practices; high-, middle- and low-income countries should support each other appropriately in delivering sustainable healthcare (including anaesthesia); and healthcare systems should be mandated to reduce their contribution to global warming. We set out seven fundamental principles to guide anaesthesia providers in the move to environmentally sustainable practice, including: choice of medications and equipment; minimising waste and overuse of resources; and addressing environmental sustainability in anaesthetists’ education, research, quality improvement and local healthcare leadership activities. These changes are achievable with minimal material resource and financial investment, and should undergo re-evaluation and updates as better evidence is published. This paper discusses each principle individually, and directs readers towards further important references. 相似文献

Climate change education in advanced practice registered nursing curricula prepares nurse practitioners to respond to the health effects of climate change. Knowledge of the relationship between human and environmental health is essential for nurse practitioners to identify, teach, and respond to the health effects of climate change in clinical and community settings. This article describes a webinar hosted by the Sarah P. Duke Gardens in partnership with the Duke University School of Nursing. Our webinar provided an opportunity for attendees to understand how gardening can mitigate climate change, the important relationship between human and environmental health, and nurses’ role in climate crisis. 相似文献

A recent United Nations (UN) report concluded that the inability to curb fossil fuel emissions from burning coal, oil, and gas has resulted in a short window of time to prevent an abysmal future. The health care industry remains one of the largest contributors to climate change. NPs must not only recognize the clinical presentations resulting from climate change but must also contribute to the efforts presented by the UN report to create a health system that does not contribute to climate change. This article reviews potential ways to decrease the health care sector’s contribution to climate change. 相似文献

Job insecurity has been recognized for its negative effect on employee
performance. Nevertheless, this study argues that, under the threat of job
insecurity, employees may also be likely to seek to reduce the threat by proactively
crafting their tasks and improving performance. Drawing from the perspective of
Vroom’s expectancy theory, it is proposed that, only when job security is at
moderate level will employees expect it as possible to make such a change to
respond to the situation. Accordingly, a curvilinear mediated model is developed
that links job insecurity and task performance indirectly through task crafting, and
a two-waved time-lagged survey involving 328 employees was conducted to test
the model. The results showed that job insecurity had an inverted U-shaped
relationship with task crafting and that this relationship was moderated by
strengths-based psychological climate, a measure of how employees feel their
strengths are appreciated in the organization. In this sense, strengths-based
psychological climate can enhance the positive relationship between job insecurity
and task crafting. Overall, the finding suggests that job insecurity may not always
be detrimental. Thus, there will be significant managerial implications in creating
favorable conditions for increased task performance. 相似文献

Recent dramatic and deadly increases in global wildfire activity have increased attention on the causes of wildfires, their consequences, and how risk from wildfire might be mitigated. Here we bring together data on the changing risk and societal burden of wildfire in the United States. We estimate that nearly 50 million homes are currently in the wildland–urban interface in the United States, a number increasing by 1 million houses every 3 y. To illustrate how changes in wildfire activity might affect air pollution and related health outcomes, and how these linkages might guide future science and policy, we develop a statistical model that relates satellite-based fire and smoke data to information from pollution monitoring stations. Using the model, we estimate that wildfires have accounted for up to 25% of PM2.5 (particulate matter with diameter <2.5 μm) in recent years across the United States, and up to half in some Western regions, with spatial patterns in ambient smoke exposure that do not follow traditional socioeconomic pollution exposure gradients. We combine the model with stylized scenarios to show that fuel management interventions could have large health benefits and that future health impacts from climate-change–induced wildfire smoke could approach projected overall increases in temperature-related mortality from climate change—but that both estimates remain uncertain. We use model results to highlight important areas for future research and to draw lessons for policy. 相似文献
