They’re called electronic visit verification apps, or EVVs. They log the hours and the movements of home health care workers paid for by Medicaid. States are just starting to roll them out as part of an Obama-era program that promised to make managing the work of home aides more efficient and reduce fraud in the system. Marketplace’s Meghan McCarty Carino speaks with Virginia Eubanks, the author of “Automating Inequality: How High-Tech Tools Profile, Police, and Punish the Poor.” She’s been following Arkansas’ implementation of EVVs and co-wrote a story about it for the Guardian newspaper. Eubanks said the state’s app has been glitchy, which led to missed paychecks for aides.
