Abstract
A growing body of research emphasises the role of ‘social determinants of health’ in generating inequalities in health outcomes. How, if at all, should primary care providers respond? In this paper, I want to shed light on this issue by focusing on the role that ‘big data’ might play in allowing primary care providers to respond to the social determinants that affect individual patients’ health. The general idea has been proposed and endorsed by the Institute of Medicine, and the idea has been developed in more detail by Bazemore et al. (2016). In Bazemore et al.’s proposal, patients’ addresses are used to generate information about the patients’ neighbourhood; this information is then included in patients’ health care records and made available to providers. This allows primary care providers to take this information into account when interacting with, and providing care to, patients. I explore three issues arising from this proposal. First, while questions of privacy have been central to discussions about big data, Bazemore et al.’s proposal also allows us to see that there might be costs to not making certain information available. Second, I consider some of the questions arising for primary care from the influence of social factors on health outcomes: given that we know these factors to be significant contributors to social inequalities in health, what precisely should be done about this in the primary care context? Finally, I address problems arising from the use of population level data when dealing with individuals.

Notes
See, for example, Murdoch and Detsky (2013).
I treat the two papers cited here as developing the same proposal because there is significant overlap between the groups of authors of the two papers: all the authors of Hughes et al. (2016) are also authors on Bazemore et al. (2016); an additional five authors contributed to Bazemore et al. (2016). Bazemore et al. (2016), which is more detailed than Hughes et al. (2016), is the primary source of information for this paper.
For example, because in certain ways of generating data (such as social media), disadvantaged populations are likely to be underrepresented (Hargittai 2015).
See Braveman et al. (2011) for a review of the available evidence.
See also Starfield et al. (2012) for more general discussion. While my focus in this paper is on industrialised countries, concerns about possible increases in health inequality arising from the introduction of universal health care have also been raised in the context of low-income countries (e.g. Gwatkin and Ergo 2011).
See Nuffield Council on Bioethics (2015) for discussion.
The Institute of Medicine also notes that information about social factors may be sensitive to patients. They suggest that providers may therefore want to treat this information differently from other kinds of information but also caution that this approach might perpetuate stigma surrounding particular social factors (Institute of Medicine 2015b: 332).
An interesting example of these kinds of mechanisms is provided by Carla Shedd’s (2015) study of students from different Chicago schools, whose assessment of racial injustice varied depending on how much they moved between neighbourhoods with different levels of affluence and diversity: for Black students who did not leave their neighbourhoods to attend school in a more affluent area, frequent negative encounters with police were ‘normal’ whereas those students who attended schools in more affluent neighbourhoods became aware of differences in police presence and behaviour between different areas.
In fact, ensuring usefulness of the recommendations providers give to their patients is part of what the Institute of Medicine envisages (Institute of Medicine 2015b).
See also Sniderman (2015) for discussion of this concern.
