The research, published in BMC Medicine, was led by researchers from the Cicely Saunders Institute at King's College London in collaboration with King’s College Hospital Foundation Trust (UK), Trinity College Dublin (Ireland), Mater Misericordiae Hospital (Ireland), Beaumont Hospital (Ireland), University of Bristol (UK), University of California, San Francisco (USA) and Icahn School of Medicine at Mount Sinai (USA).

The study surveyed 767 carers in three countries about the last three months of life for the person they cared for.

Researchers concluded that there was an urgent need in all three countries to improve the integration and support for dedicated community palliative care services to improve the care quality and support people across the whole journey of care.

This is the first study of its kind and found:

• Costs to informal carers are larger than those to formal care services (health, social and voluntary combined) for people in the last three months of life. 
• Poor quality home care was associated with greater burden to carers.
• If well supported informal carers can play an important role in providing care, and this can be done without detriment to them, providing that they are helped.
• Improving community palliative care and informal carer support should be a focus for future investment.  

In the last three months of life, formal care costs are high, but little is known about the costs of informal care and their effects on outcomes. This research is an important contribution to increasing the recognition and understanding of the effort and costs of informal carers, such as families and friends, who do so much. As well as identifying areas where support and investment could help improve care for both the patient and informal and formal carers.

The study uses the experiences reported by informal carers to determine and compare the informal care costs and their associations with the burden, rewards and subsequent grief, taking the quality of care into account.

The research surveyed 767 carers in London, Dublin, New York and San Francisco. Participants reported the hours and activities of informal care they gave, care quality, the positive aspects and burdens of caregiving, and completed the Texas Revised Inventory of Grief (TRIG).

All costs (formal, informal) were calculated by multiplying reported hours of activities by country specific costs for that activity. Informal care costs used country-specific shadow prices, e.g. average hourly wages, unit costs for nursing care. The study also examined the positive aspects and burdens of caregiving, and the carer’s subsequent grief.

Professor Irene Higginson lead of the study said: "Family and friend carers do so much in helping people who need palliative care. Alongside being a wife, husband, partner, daughter, son, friend or other relation, our study shows the huge amount of practical help, advocacy, co-ordination and 'being there' that they provide. This costs more to society that do the formal care services, and when home care is of poor quality the burden on informal carers increases."

Dr Lucy Selman, Senior Research Fellow at the University of Bristol, conducted the study at the University of California, San Francisco with Dr Steve Pantilat. She said: "Family and friends provide essential practical and emotional support as people approach the end of life. In this international study, we found that, if paid, the care provided by family and friends would cost more than all the formal care provided by the healthcare system. The rewards of caregiving made grief easier to deal with, but caregiving also took a toll. Palliative care services play a crucial role in supporting caregivers to improve their quality of life and the well-being of the person they are caring for."

The research was funded by Cicely Saunders International, The Atlantic Philanthropies and the National Institute for Health Research Applied Research Collaboration South London.
