Research is important because it underpins evidence-based care. However, people who lack capacity to consent are often excluded from research, due partly to ethical concerns and practical challenges, and partly to a lack of awareness among professionals of the legal framework that supports their inclusion. The COVID-19 pandemic, which has extensively affected care home residents, has reinforced the importance of including older people with cognitive impairment in research. Nurses who care for older people with impaired cognition have an important role in ensuring these people have the opportunity to contribute to and benefit from research.

This article discusses some of the challenges associated with the inclusion in research of older people who lack capacity to consent, including the involvement of relatives and friends in decision-making. The article describes the findings of recent research and shares resources with the aim of supporting nurses to ensure that older people in their care who lack capacity can participate in research.
