Input: Four studies involving 1642 participants made three eligible comparisons: (i) personal assistance versus usual care, (ii) personal assistance versus nursing homes, and (iii) personal assistance versus 'cluster care'. One was an RCT, three were non-randomised. Personal assistance was generally preferred over other services; however, some people prefer other models of care. This review indicates that personal assistance probably has some benefits for some recipients and caregivers. Paid assistance probably substitutes for informal care and may cost government more than alternatives; however, the total costs to recipients and society are currently unknown. Research in this field is limited. Personal assistance is expensive and difficult to organise, especially in places that do not already have services in place. When implementing new programmes, recipients could be randomly assigned to different forms of assistance. While advocates may support personal assistance for myriad reasons, this review demonstrates that further studies are required to determine which models of personal assistance are most effective and efficient.
Output:

This review investigated the effectiveness of personal assistance versus any other form of care for older adults (65+). An exhaustive literature search identified 4 studies that met the inclusion criteria, which included 1642 participants. They suggested that personal assistance may be preferred over other services; however, some people prefer other models of care. This review indicates that personal assistance probably has some benefits for some recipients and their informal caregivers. Paid assistance might substitute for informal care and cost government more than alternative arrangements; however, the relative total costs to recipients and society are unknown.
