Health and access to health care vary strikingly across the globe, and debates about this have been pervasive and controversial. Some comparative data in Canada and South Africa illustrate the complexity of achieving greater equity anywhere, even in a wealthy country like Canada. Potential bi-directional lessons relevant both to local and global public health are identified. Both countries should consider the implications of lost opportunity costs associated with lack of explicit resource allocation policies. While National Health Insurance is attractive politically, Canada's example cannot be fully emulated in South Africa. Short- and medium-term attempts to improve equity in middle-income countries should focus on equitable access to insurance to cover primary health care and on making more use of nurse practitioners and community health workers. In the longer-term, attention is needed to the economic and political power structures that influence health and health care and that ignore the social and societal determinants of sustainable good health locally and globally. This long-term vision of health is needed globally to achieve improvements in individual and population health in a century characterised by limits to economic growth, widening disparities, continuing conflict and migration on a large scale and multiple adverse impacts of climate change.  相似文献

Objective

To understand market managers' level of communication and use of technology that might influence decision to adopt Electronic Benefits Transfer (EBT) at farmers' markets.

Design

Cross-sectional study using the Theory of Diffusion of Innovation.

Setting

Electronic survey administered in midwest states of Illinois, Michigan, and Wisconsin.

Participants

Farmers' market managers in Illinois, Michigan, and Wisconsin.

Main Outcome Measures

Information on EBT adoption, market managers' communication, and technology use.

Analysis

Binary logistic regression analysis with EBT adoption as the dependent variable and frequency of technology use, partnership with organizations, farmers' market association (FMA) membership, Facebook page and Web site for the market, and primary source of information as independent variables. Chi-square tests and ANOVA were used to compare states and adopter categories.

Results

Logistic regression results showed that the odds of adopting EBT was 7.5 times higher for markets that had partnership with other organizations. Compared with non-adopters, a significantly greater number of early adopters had partnership, FMA membership, and a Facebook page and Web site for market, and reported to a board of directors.

Conclusions and Implications

Markets that had partnership, FMA membership, a Facebook page and Web site, and mandatory reporting to a board of directors were important factors that influenced EBT adoption at midwest farmers' markets.  相似文献

Introduction: A range of devices are available for delivering and monitoring home oxygen therapy (HOT). Guidelines do not give indications for the choice of the delivery device but recommend the use of an ambulatory system in subjects on HOT whilst walking.

Areas covered: We provide a clinical overview of HOT and review traditional and newer delivery and monitoring devices for HOT. Despite relevant technology advancements, clinicians, faced with many challenges when they prescribe oxygen therapy, often remain familiar to traditional devices and continuous flow delivery of oxygen. Some self-filling delivery-less devices could increase the users’ level of independence with ecological advantage and, perhaps, reduced cost. Some newer portable oxygen concentrators are being available, but more work is needed to understand their performances in different diseases and clinical settings. Pulse oximetry has gained large diffusion worldwide and some models permit long-term monitoring. Some closed-loop portable monitoring devices are also able to adjust oxygen flow automatically in accordance with the different needs of everyday life. This might help to improve adherence and the practice of proper oxygen titration that has often been omitted because difficult to perform and time-consuming.

Expert commentary: The prescribing physicians should know the characteristics of newer devices and use technological advancements to improve the practice of HOT.  相似文献

随着经济全球化的发展和国际竞争环境的日趋复杂,药品研发已成为制药企业应对竞争环境不确定性的最有力武器。笔者以制药行业为研究视角,立足于五行理论,运用取象比类思维,进行五行理论与企业家类型系统的取象比类研究。在企业家类型系统和企业管理系统的基础上,嵌入企业高层管理团队系统,将企业家纳入系统并根据企业家的不同特征属性为其分配角色,通过对不同企业家与研发负责人的“生克乘侮”关系的分析,阐述不同类型企业家对企业药品研发环节(立项、过程及结果)的影响。旨在为不同类型的企业家提供药品研发创新及内部协同的管理思路,以利于企业家基于自身特征进行利弊分析,有效提升企业内部资源整合能力和药品研发自主创新能力。  相似文献
