Social Justice, Equality and Primary Care: (How) Can ‘Big Data’ Help?

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.. 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.
