The Working Group on Arbitrary Detention can deal with detention based on discrimination of any kind. In the case of older people it is often a combination of age and actual or perceived disability but it can also be age alone. The WGAD has spoken out against forced treatment in the mental health context because of the linkage with arbitrary detention, which is their particular mandate. People in skilled nursing facilities might be in a situation of detention if they can’t leave; you would need to check and compare with how the WGAD defines detention, this might be a place to start: http://www.ohchr.org/EN/HRBodies/HRC/RegularSessions/Session30/Documents/A_HRC_30_37_ENG.docx But that is only one of a number of UN human rights mechanisms that we can address. Here is the web page for the UN Independent Expert on the enjoyment of all human rights by older persons: http://www.ohchr.org/EN/Issues/OlderPersons/IE/Pages/IEOlderPersons.aspx. You might want to write to her about the problem and give her information about how it is taking place, whether in the US or in any other countries you know of. There is also other work at the UN on the rights of older persons described here http://www.ohchr.org/EN/Issues/OlderPersons/Pages/OlderPersonsIndex.aspx including a process to create a new treaty, that is taking place in New York-based meetings roughly once a year, https://social.un.org/ageing-working-group/index.shtml. Get involved and bring this abuse to their attention; I am trying to stay involved but it’s difficult to relate to a second treaty process after the CRPD one. I can advise about human rights law and how to frame these issues to relate with the legal concepts and framework.
