 The term "caregiver" may be prefixed with "live-in", "family", "spousal", "child", "parent", "young" or "adult" to distinguish between different care situations, and also to distinguish them definitively from the paid version of a caregiver, a Personal Care Assistant or Personal Care Attendant (PCA).Around half of all carers are effectively excluded from other paid employment through the heavy demands and responsibilities of caring for a vulnerable relative or friend.The term "carer" may also be used to refer to a paid, employed, contracted PCA.
