Approximately 75% of healthcare costs are allocated towards treating those with chronic diseases. In the spirit of the linked article, I agree that internet connectivity and associated hardware and sensors (the so-called internet of things) has the potential to improve the preventative treatment of chronic diseases. The idea behind this logic is that access to additional metrics and data regarding personal health will either "nudge" individuals to make personal improvements or that this data will be more easily shared with clinicians (who could presumably act upon this information).

Rapidly increasing smartphone penetration globally will ideally facilitate improvements in health care beyond the West. It seems possibly the even-larger gains could be made in resource-limited environments.

Nevertheless, my primary concern regarding this trend is the disconnect that it could create between patients and clinicians. Patients may draw conclusions on information that they are able to attain without the insights of an experienced professional. While this is beneficial in some contexts, it could be potentially harmful in others. Outside of clinical settings, I believe that our use of the internet of things in healthcare must be scaled intentionally with the support of rigorously-tested evidence.
