AbstractWith a policy shift towards personalisation of adult social care in England, much attention has focused on individualised support for older people with care needs. This article reports the findings of a scoping review of United Kingdom (UK) and non-UK literature, published in English from 2005 to 2017, about day centres for older people without dementia and highlights the gaps in evidence. This review, undertaken to inform new empirical research, covered the perceptions, benefits and purposes of day centres. Searches, undertaken in October/November 2014 and updated in August 2017, of electronic databases, libraries, websites, research repositories and journals, identified 77 relevant papers, mostly non-UK. Day centres were found to play a variety of roles for individuals and in care systems. The largest body of evidence concerned social and preventive outcomes. Centre attendance and participation in interventions within them impacted positively on older people's mental health, social contacts, physical function and quality of life. Evidence about outcomes is mainly non-UK. Day centres for older people without dementia are under-researched generally, particularly in the UK. In addition to not being studied as whole services, there are considerable evidence gaps about how day centres are perceived, their outcomes, what they offer, to whom and their wider stakeholders, including family carers, volunteers, staff and professionals who are funding, recommending or referring older people to them.
