Social care is an increasing important public service, but little is known about its impact and how effective or efficient different care interventions are. To help remedy this situation, RAND Europe has undertaken research for the Office of National Statistics and the Personal Social Services Research Unit that quantifies the value placed on different aspects of social care related quality of life. This research forms part of the new Adult Social Care Outcomes Toolkit (ASCOT), which provides a tool for commissioners, service providers and regulators to quantify the outcomes of care interventions and help prioritise expenditure in areas which offer the greatest return to service users.
