Where to start my search for sister's in-home care?

Start calling around. Do not ask if she is there just act like you know she is and you need a room number to send a card. When they say no one by that name you go to the next care home.

This is a global caregiving forum, most people on it are living in the US. We cannot help you find a missing family member, mostly because there may be legalities involved and we don't know what your reason is for seeking her. Please work through social services, the hospital or the police in her local area/country.

Ttrying to find the home she is in have rang social services but they can't help due to I live in worthing sussex
