A special unit within a nursing home for serving residents with dementia was developed and implemented at the Cape Cod Nursing Home in Buzzards Bay, Massachusetts. The purpose of the special unit is to create a structured and protective environment which holistically supports the residents with dementia in achieving their maximum potential. A program designed to help the residents' families adjust to the changing roles and relationships made necessary by the progression of the disease accompanies the unit. The unit was designed with wall coverings and furniture in warm colors, washable carpeting, door alarms for security, family-atmosphere dining, and an activity room. The unit is staffed by nurses, nursing assistants, and a program assistant, the majority of whom have chosen this assignment. Admission criteria is based on a diagnosis of Alzheimer's Disease or related dementia. Support systems for staff, family, and residents are emphasized. Problem behaviors and safety issues such as depression and combativeness are anticipated and addressed in patient care planning. Public health proposals should address the difficulty nursing homes experience in seeking psychiatric care for patients with severe problem behaviors associated with Alzheimer's Disease. (ABL)
