Pd. Sloane et al., EVALUATING ALZHEIMERS SPECIAL CARE UNITS - REVIEWING THE EVIDENCE ANDIDENTIFYING POTENTIAL SOURCES OF STUDY BIAS, The Gerontologist, 35(1), 1995, pp. 103-111
Special Care Units (SCUs) for Alzheimer's disease have been proliferat
ing in long-term care, but their effectiveness remains unproven. This
review summarizes the published studies, presents and discusses the ma
ny potential sources of bias that pose special problems for SCU resear
ch, and proposes strategies for conducting and interpreting future out
come studies in this difficult research setting.
