The value of healthcare data: to nudge, or not?

The processes of datafication, digitization and automation of healthcare and medicine are making new types and data available for analysis, and at greater volume. While the newly available data is often hailed as a solution to various problems in healthcare, there is only little discussion about who the use of such data empowers and who bears the costs. The use of healthcare data for “nudging”–e.g. to get patients to adopt healthier lifestyles–is a case in point: While such interventions are presumed to be cheap and effective, I argue that their value is a priori unclear. Both because of its assumed value-freeness, and because of its focus on individual behaviour, nudging draws attention away from the societal, political and economic factors that shape human practice. I conclude with a call upon policy makers to facilitate the use of healthcare data to build better institutions and to address social determinants of health before they seek to “fix” individual behaviour through nudging.
