Abstract:
Special Care Units (SCUs) for Alzheimer's disease have been proliferating in long-term care, but their effectiveness remains unproven. This review summarizes the published studies, presents and discusses the many potential sources of bias that pose special problems for SCU research, and proposes strategies for conducting and interpreting future outcome studies in this difficult research setting.
