Initial Research Design of the National Long Term Care Demonstration


The primary objective of the research in the National Long-Term Care Channeling Demonstration was to determine the impacts of the demonstration on service utilization, public and private costs, clients and caregivers. The demonstration employed a randomized experimental design with random assignment of eligible participants to either treatment group or control group status. The sample was designed so that six percentage points was the minimum reduction in the nursing home institutionalization rate that could be detected (with 90% power). The statistical technique used for much of the impact estimation was multiple regression. Potential problems such as non-comparability of baseline data and sample attrition were examined separately.
