As social services councils face a more constrained economic environment and as eligibility criteria tighten, the issue of targeting becomes increasingly relevant. This paper presents findings from a pilot project in one local authority that aimed to target access to assessment for older people with low-level needs who would normally have fallen under eligibility thresholds. Self-assessment was used as a tool whereby these older people could identify, with assistance, their preferences for a range of preventative services. Via a randomised design, the study evaluated the costs and benefits, in terms of reported satisfaction, of the approach compared with the usual care management assessment. Although self-assessed cases were offered more advice as to a wider range of preventative services, which generated greater costs, total costs were lower for this group. This cost saving arose from the use of staff with a lower unit cost who also spent less time on administrative duties and gathering information. Satisfaction with self-assessment was comparable to a professional assessment, therefore representing a cost-effective approach. The project offers evidence of how councils can target resources through assessment and how self-assessment approaches may be appropriately configured to offer value for these users whilst also generating resource savings.
