From Kendra Scalia's Electronic Visit Verification (EVV) is Here:  What you need to know and how to get involved:

"Moreover, EVV systems erode the intent of consumer-directed services, walking us back in time 40 years where disabled people are no longer in control of their private lives.  Without consumer-directed services or adequate home care employees to assist us in our homes, many disabled people will have no other option than to be placed in a nursing home.  This is the antithesis of the spirit of independent living and would violate the Supreme Court Olmstead decision, which requires states to offer services in a home and community-based setting when they also provide nursing home care.
