Digital health & low-value care.

Digital health advances offer a multitude of possibilities to improve public health and individual wellbeing. Little attention has been paid, however, to digital health's potential to create low-value care - the reduction of which is increasingly appreciated as a policy priority. This commentary provides a framework to illustrate the potential for consumer-facing digital health to generate three distinct categories of low-value care; 1) ineffective care because it is underdeveloped, 2) inefficient care because it supplements rather than substitutes, or 3) unwanted care because it is not aligned with clinician and patient preferences. We offer specific policy recommendations to reduce each type of low-value care.
