Introduction: An estimated 6.8 million people are (informal) carers in the UK. The economic value of annual carer contributions is an estimated .·132bn. Reliance on carers appears to be increasing. There is mixed evidence on whether carers are substitutes for formal care. This study investigated the association between having a carer and service use patterns across five care settings when compared to a matched cohort without a carer.
Materials and methods: A matched case-control group analysis using person-level data in Barking and Dagenham (B&D), a London borough in the U.K., to assess the impact of having a carer in terms of the differences in cost-weighted utilisation relative to a matched control group.
Results: In 2016/17, for adult residents of B&D, having a carer (n = 1,295) was associated with 27% increased cost-weighted utilisation (mean difference of £2,662, CI £1,595, £3,729, p<0.001) compared to a matched cohort without a carer. 39% of the cost difference was social care.
Conclusions: Findings suggest additional service use induced by carers may dominate any substitution effect. Having a carer may be a key element in enabling access to services. As such, there may be wider inequalities in service access for people without a carer. For an ageing society with projections suggesting there will be more people without carers in the future, these inequalities need to be addressed.
