Employers Take Note: Premium-Based Incentives For Weight Loss Don't Work

Jan. 5, 2016

A new study casts doubt on the effectiveness of reducing health insurance premiums as a way to encourage employees to lose weight. LDI Senior Fellow Mitesh Patel and his team, in a randomized controlled trial, test the effectiveness of a $550 incentive in promoting weight loss in obese employees. They found no difference in weight loss over the course of one year between the control group and three different kinds of incentive programs.

In Epidemiology, Douglas Wiebe and colleagues, including Therese Richmond and Charles Branas, investigated the interplay between urban youth’s lived experiences, time spent in different environments, and risk of violent assault. The researchers mapped activity paths of 10- to 24-year olds, comparing community controls, emergency department patients assaulted with a firearm, and patients assaulted with another type of weapon. Through interviews, the investigators created a record of how, when, where and with whom subjects spent time over a full day. Tracing back activities through...

In Injury Prevention, Catherine McDonald and colleagues, including Flaura Winston, evaluate the construct and criterion validity of the Simulated Driving Assessment (SDA). The SDA is a newly developed tool for novice teen drivers that incorporates 22 variations of the most common teen driver crashes. The authors compared the driving performance of inexperienced teens with experienced adult drivers.  Their analysis shows a higher error score in teens than in adults, and that the error score derived from the SDA correlates with the score from a professional driving instructor. The...

In Infection Control and Hospital Epidemiology, Marci Drees and colleagues, including J. Sanford Schwartz, evaluate the efficacy of implementing a multimodal campaign to increase influenza vaccination among healthcare personnel (HCP) without a mandate. The authors implemented an integrated multimodal approach incorporating peer pressure, accountability, and financial incentives to improve the HCP influenza vaccination rate. Employee compliance, vaccination, exemption and declination rates were compared with those of the seasons prior to the intervention. The authors find that...

Getting More Food-Allergic Young Adults To Carry Their Epinephrine: A Behavioral Economics Approach

Sep. 3, 2015

As one of the estimated 2.5% of Americans with a food allergy, deciding my next meal, snack, or even beverage is no simple task. Remembering to carry emergency epinephrine is also no walk in the park. Young adults like me are particularly vulnerable to error related to their food allergies and likely to engage in risky behavior. And despite the risk of death by anaphylaxis, few individuals with severe food allergies carry their emergency epinephrine on a daily basis.

In the beginning (Web Site 1.0), we measured the success of health insurance marketplace sites by whether they worked. Last year (Web Site 2.0), technical glitches were resolved, and we can start to measure success by whether the sites help people make the best decisions in choosing a health plan.
