A caregiver can be defined as a person – possibly a relative or a friend – who provides unpaid support to someone who is ill, disabled, elderly, or a child. There are estimated to be around 8.8 million informal caregivers in the UK¹. According to a recent Carers UK survey, not only has the number of caregivers increased since the start of the COVID-19 pandemic², but caregivers have been taking on increasing hours of care, often with less or no outside support. In the same survey, 55% of respondents admitted feeling overwhelmed by their caregiving duties. The contribution made by caregivers to society is not insignificant; estimates suggest that unofficial provision of care saves the economy £132 billion per year³. Decision-makers acknowledge the importance of including caregiver evidence to help build a more complete picture of the impact of disease. In fact, caregiver outcomes are newly recognized by the National Institute for Health and Care Excellence (NICE) in their updated health technology evaluation manual.
