Hand hygiene to reduce community transmission of influenza and acute respiratory tract infection: a systematic review.

Hand hygiene may be associated with modest protection against some acute respiratory tract infections, but its specific role in influenza transmission in different settings is unclear. We aimed to review evidence that improving hand hygiene reduces primary and secondary transmission of (i) influenza and (ii) acute respiratory tract infections in community settings. We searched Medline, Embase, Global Health and Cochrane databases up to 13 February 2012 for reports in any language of original research investigating the effect of hand hygiene on influenza or acute respiratory tract infection where aetiology was unspecified in community settings including institutions such as schools, and domestic residences. Data were presented and quality rated across outcomes according to the Grading of Recommendations Assessment, Development and Evaluation system. Sixteen articles met inclusion criteria. There was moderate to low-quality evidence of a reduction in both influenza and respiratory tract infection with hand hygiene interventions in schools, greatest in a lower-middle-income setting. There was high-quality evidence of a small reduction in respiratory infection in childcare settings. There was high-quality evidence for a large reduction in respiratory infection with a hand hygiene intervention in squatter settlements in a low-income setting. There was moderate- to high-quality evidence of no effect on secondary transmission of influenza in households that had already experienced an index case. While hand hygiene interventions have potential to reduce transmission of influenza and acute respiratory tract infections, their effectiveness varies depending on setting, context and compliance

Obesity, liberty, and public health emergencies

Widespread obesity poses a serious challenge to health outcomes in the developed world and is a growing problem in the developing world. There has been a raft of proposals to combat the challenge of obesity, including restrictions on the nature of food advertising, the content of prepared meals, and the size of sodas; taxes on saturated fat and on calories; and mandated “healthy-options” on restaurant menus. Many of these interventions seem to have a greater impact on rates of obesity than does simply providing information about health risks and healthier lifestyles. The more interventionist policy options have, however, been implemented only slowly, in large part because of criticisms that they are unjustified infringements on the liberty of consumers. Food industry groups, free-market think tanks, and the popular press regard measures that incentivize or penalize particular food and lifestyle choices as unjustifiable state regulation of purely self-regarding behavior

Patient and Citizen Participation in Health: The Need for Improved Ethical Support

Patient and citizen participation is now regarded as central to the promotion of sustainable health and health care. Involvement efforts create and encounter many diverse ethical challenges that have the potential to enhance or undermine their success. This article examines different expressions of patient and citizen participation and the support health ethics offers. It is contended that despite its prominence and the link between patient empowerment and autonomy, traditional bioethics is insufficient to guide participation efforts. In addition, the turn to a “social paradigm” of ethics in examinations of biotechnologies and public health does not provide an account of values that is commensurable with the pervasive autonomy paradigm. This exacerbates rather than eases tensions for patients and citizens endeavoring to engage with health. Citizen and patient participation must have a significant influence on the way we do health ethics if its potential is to be fulfilled
