Special care units: a typology of care settings for memory-impaired older adults.

After rating 55 nursing homes in five states, we created a typology of care settings that included eight distinct types of units designed to care for memory-impaired older adults. SCUs appeared to be associated with higher quality care than were traditional units, although quality of SCU care was not uniformly outstanding. This typology provides guidelines that can be used in preresidential analysis of prospective care units for demented older adults.
