Raina Merchant and colleagues want to raise awareness about automated external defibrillators (AEDs) and use artwork to make AED locations more memorable. In a recent article in the American Journal of Public Health, Merchant et al use an online crowdsourcing design contest -- the Defibrillator Design Challenge -- to engage the public to this end. The goal of the project was not to install designs submitted as part of the contest, but to test whether the public would create them, vote on them, and share them. It is a follow-up to...

Cross-Border Effects of State Health Technology Regulation

Feb. 11, 2015

Jill R. Horwitz, Daniel Polsky

In the American Journal of Health Economics, LDI Executive Director Daniel Polsky and Jill R. Horwitz (UCLA School of Law) explore whether state Certificate of Need (CON) laws have an effect on the supply of medical technology in neighboring states. They studied whether MRI providers disproportionately locate in unregulated states in counties that border states regulated by CON licensing laws. They found a sizable cross-border effect: among counties located on state borders where one state regulates MRI entry and the other state does not, there is more likely to be an MRI provider in the...

Wearable Devices as Facilitators, Not Drivers, of Health Behavior Change

Feb. 3, 2015

Mitesh S. Patel, David A. Asch, Kevin G. Volpp

In a commentary in the Journal of the American Medical Association, Mitesh Patel, David Asch, and Kevin Volpp discuss the validity of claims that wearable devices promote long-term healthy behaviors. The authors contend that, although they may be useful in facilitating behavioral change in individuals already motivated to do so, using wearable devices to motivate people to instigate healthy changes is a challenge. Relatively high prices, potential inaccuracy of metrics, inconsistency of use, and difficulties in sustaining motivation are all significant barriers to success. Getting patients...
