Precision public health-the Emperor's new clothes

Recently the Centre for Disease Control suggested that ‘precision public health’ presents significant opportunities to improve the health of the population,1 but what does this concept add and does it live up to the hype? The promise is that by harnessing the power of Big Data, particularly genomic data, we may indeed see early gains in public health as a result of ‘more-accurate methods for measuring disease, pathogens, exposures, behaviors, and susceptibility’ to guide targeted prevention strategies.2 However, the term ‘precision public health’ is susceptible to misinterpretation. Long before Big Data in the form of personalized genetic and epigenetic profiling arrived, much public health screening and prevention strategy was premised on varying degrees of targeting and stratification, so this is nothing new. Nevertheless, others in the UK have used analogous terms such as ‘personalized prevention’ or ‘personalized public health’, representing them as part of an urgent agenda in which we must ‘reap the benefits of the genomic revolution’.3 The purpose of this article is therefore to highlight some of the evidentiary and philosophical challenges for the concept of ‘precision public health’ which have not been exposed to sufficient scrutiny. It is also to argue for a more considered focus beyond the genome, lest we career headlong towards a diversion of resources, away from what really matters, to the detriment of population health. To do this, we structure our critique by aligning it with the so-called population perspective on precision medicine (i.e. the ‘P4 approach’), namely that precision public health should aim to be Predictive, Preventive, Personalized and Participatory.4 The advantage of taking this approach is that whereas it focuses on the key dimensions and parameters of the decisions that could help improve care both for individuals and populations, it has gained traction among precision medicine proponents themselves. Thereafter we return to the more philosophical and ethical arguments that should remind us of a bigger picture and the trade-offs that we might be making by investing in ‘precision public health’

Students' attitudes to the communications employed during an outbreak of meningococcal disease in a UK school: a qualitative study.

BackgroundFollowing an outbreak of meningococcal disease in a school in the North West of England, the communication methods employed by the Health Protection Agency (HPA) were evaluated in order to explore ways of improving communication with the public.MethodsQualitative questionnaires were distributed to Year 12 (sixth form) students. The Framework approach was used to analyse the data, which were coded, and emergent themes identified.ResultsIn the absence of clear communication from official sources, many participants suggested that circulating rumours caused confusion and anxiety in the student population. Rumours were spread through informal networks in person or through text and MSN messaging. It was generally perceived that accurate information in this period would have been useful to allay potentially unfounded anxiety. Most students surveyed reported that they were sufficiently aware of the situation prior to receiving official announcements. The information provided by the HPA through the school was generally perceived as being useful, but it came too late.ConclusionIn outbreak situations, rumours will spread rapidly in the absence of early communication, and this can be a significant cause of anxiety. The use of digital communication strategies should be considered, since they can seed dependable information that will disseminate rapidly through peer groups

Pathways to inequalities in child health

No abstract available.From birth, children living in disadvantaged socioeconomic circumstances (SECs) suffer from worse health than their more advantaged peers. The pathways through which SECs influence children’s health are complex and inter-related, but in general are driven by differences in the distribution of power and resources that determine the economic, material and psychosocial conditions in which children grow up. A better understanding of why children from more disadvantaged backgrounds have worse health and how interventions work, for whom and in what contexts, will help to reduce these unfair differences. Macro-level change is also required, including the reduction of child poverty through improved social security systems and employment opportunities, and continued investment in high-quality and accessible services (eg, childcare, key workers, children’s centres and healthy school environments). Child health professionals can play a crucial role by being mindful of the social determinants of health in their daily practice, and through advocating for more equitable and child-focussed resource allocation

Suicides associated with the 2008-10 economic recession in England: time trend analysis.

OBJECTIVE: To determine whether English regions worst affected by the economic recession in the United Kingdom in 2008-10 have had the greatest increases in suicides. DESIGN: Time trend analysis comparing the actual number of suicides with those that would be expected if pre-recession trends had continued. Multivariate regression models quantified the association between changes in unemployment (based on claimant data) and suicides (based on data from the National Clinical Health Outcomes Database). SETTING: 93 English regions, based on the Nomenclature of Territorial Units Statistics level 3 groupings of local authorities at county level and groups of unitary local authorities. PARTICIPANTS: Men and women with a record of death from suicide or injury of undetermined cause in 2000-10. MAIN OUTCOME MEASURE: Number of excess suicides during the economic recession (2008-10). RESULTS: Between 2008 and 2010, we found 846 (95% confidence interval 818 to 877) more suicides among men than would have been expected based on historical trends, and 155 (121 to 189) more suicides among women. Historically, short term yearly fluctuations in unemployment have been associated with annual changes in suicides among men but not among women. We estimated that each 10% increase in the number of unemployed men was significantly associated with a 1.4% (0.5% to 2.3%) increase in male suicides. These findings suggest that about two fifths of the recent increase in suicides among men (increase of 329 suicides, 126 to 532) during the 2008-10 recession can be attributed to rising unemployment. CONCLUSION: The study provides evidence linking the recent increase in suicides in England with the financial crisis that began in 2008. English regions with the largest rises in unemployment have had the largest increases in suicides, particularly among men
