OP so you know first off some things you or general public may not ever know is #1 if a group home client has a history of elopement or not . Some Ghs permit over nights to sleep during part of shift some have clients whose ISPs and Risk assessments require 24/7 awake supervison when client is in the home . Not all GHs have alarmed windows or doors what is needed for each home varys client by client. Now as to being hit by a car, thats a shame but its different issue than the GH operator & GH staff. If the homes operator did not require staff to keep the alarm on while this client was in home then the staff cannot be blamed for alarm not being on. Some GH operators have a policy requiring room checks during sleeping hours at aprox intervals to make sure client is actually in room ( x number of times during houses over night room time hours ) . ( invasion of privacy likely so) Now If the local licensing agency or state required a plan to reduce the odds of this happening again one will be written by GH operator. In GHs where a client with well established elopement history resides many GH operators have alarmed doors & windows as well as keep a second staff on hand at a asleep hourly rate in order to maintain staffing should one staff have to leave the home as part of a elopement protocol. There are so many things that as member of the public you will never know since the GH clients rights to privacy come into play, Do know this with many GH clients first off they dont live inthem because they choose it , many are court ordered. Second with many GH clients theres no way to predict any behaviour inc first times for a particular behavior be it elopement or physical aggression or any other behavior that is not socially acceptable. Especially when the GH client is newer to the system , the GH staff is trained and will as part of daily logging note new things that come up and as issues come up then things are done to address changes that may be needed to client ISP ( the news didnt say how long the client had been in the system did it? )
