A high proportion of people in care homes have dementia and many have co-existing physical health problems and/or additional mental health needs. An integrated Care Home Support Service (CHSS) delivers care and treatment of both physical and mental health problems at an early stage of development. This integrated service combines two approaches which have been shown to be effective in randomised control trials and open studies in a stepped care model. Evidence suggests it is feasible to implement some elements of such approaches into a specialist mental health NHS context. However, no widespread implementation of this combined approach had been undertaken in an NHS context until the integration of this Care Home Support Service.
