The National Administration on Aging, through the National Center on Elder Abuse, has released a report on the Elder Justice Road map Project, aimed at preventing elder abuse. I highly recommend you read about this project, at the least look over the executive summary.
I have no doubt the fruits of this effort will trickle down to impact your care giving roles, and will produce helpful resources as well. See this link to learn more: http://www.aginginplace.org/guide-to-recognizing-elder-abuse/
