From rooted in Rights' Electronic Visit Verification: a Threat to Independence for Disabled People:

"There are a lot of problems with EVV that have disabled people raising concerns.  One is the rigidity of the system, which in some cases could require EOR's to wake up in the middle of the night to sign off on attendants' hours.  For others, people who perform multiple kinds of services may struggle to classify them.  What happens when someone walks into the house, helps someone with toileting, washes some dishes, and then preps some medication?  These may be classified as different services, and have to be logged independently.  Problems with logging services accurately are a big concern, says Borel, who notes that it's already hard to find qualified workers and worries EVV may be a deterrence."
