Health economic evaluations of interventions for supporting adult carers in the UK: a systematic review from the NICE Guideline.

BACKGROUND

Policy making increasingly needs cost-effectiveness evidence to inform resource allocation. The objective of this review is to identify and to investigate evidence evaluating the cost-effectiveness of interventions aimed to support adult carers, drawing on the National Institute for Health and Care guideline on Supporting Adult Carers.

METHODS

The protocol of the review was aimed to identify the economic studies published from 2003 onwards on all types of interventions for supporting adult carers. The applicability to the review and methodological quality of included economic evaluations were assessed using pre-established checklists specified in the National Institute for Health and Care (NICE) manual for developing guidelines.

RESULTS

Our search yielded 10 economic evaluations. The main types of strategies evaluated were psychological and emotional support, training, and education support interventions. We found that the interventions more likely to be cost-effective were usually tailored to the specific carers' circumstances and delivered face-to-face and were multi-component in nature, including elements of psycho-education, training, psychological and practical support. The narrative synthesis of results indicated a wide variation in cost-effectiveness findings and methodological quality.

CONCLUSIONS

This article indicates that systematic reviews of economic evaluations can be considered as an appropriate means to support decision makers in allocating health and social care resources. Given the high economic and social impact of unpaid caring, and based on the research gaps identified, we recommend that future economics research should be targeted on interventions for identifying carers; and programs for providing carers with support and advice to help them to enter, remain in or return to paid work.
