Incentive contract design for food retailers to reduce food deserts in the US

In the US, obesity affects over 37% of the adult and over 16% of the child and adolescent population. Although not-for-profit agencies cannot directly control what a person eats, they can influence the supply side of the obesity epidemic by incentivizing food retailers to open stores in regions of the US where healthy food options do not exist. CHOT researchers present an incentive contract design for food retailers to reduce food deserts in the US. These subsidies are designed to create financially viable conditions for food retailers to offer high quality, healthy food alternatives. The researchers developed optimization models to determine the most effective and equitable resource allocations. The impact of retailer location on obesity rate is based on estimates of marginal effect of incentives on obesity rate. Given an example initiative in metropolitan Atlanta, Georgia and surrounding counties, the overall countywide obesity rate would decrease by 1.17%. This incentive contract design strategy is a positive step toward ensuring that the underserved US population has better access to healthy foods while helping solve the obesity epidemic.

Reducing Rate of Hospital Acquired Infections through Active Barrier Apparel

Healthcare professionals are at great risk of contracting healthcare-associated infections, but appropriate workplace apparel technology can provide a protective barrier.  CHOT researchers recently wrote an editorial that outlines guidance from professional societies and legislative actions that have provided positions on active barrier apparel as a best practice for healthcare apparel. This type of technology can replace today’s traditional apparel or uniforms, such as scrubs and white coats worn in healthcare settings throughout the United States.
