A local census of dementia sufferers

The results of a census of all dementia sufferers known to institutional and community services in Angus are reported. A total of 859 sufferers were identified compared with an expected 1013 based on EURODEM prevalence rates. After allowing for cross-boundary flow to institutions, it was estimated that the true identification rate was 80% (809/1013). Of the estimated total 1063 sufferers (including cross-boundary flow): 26% were in hospital, 27% in residential or nursing homes, 27% in the community and known to services (often the GP), and 19% in the community and not known to services (or, at least, not returned by them in the census). With the co-operation of all concerned, a census approach can yield useful information at a much lower cost than a full survey.
