The cost analysis project report is directed towards persons in policy-making and administrative positions at the national, State, and direct service agency levels. Its purpose was to survey the literature and records to identify costs of homemaker-home health aide services and comparative costs of alternative forms of services. Part 1 includes summary of cost data, conclusions, and recommendations. The data were found to support the thesis that homemaker-home health aide services, when provided alone or as one of an array of in-home services, are usually less costly than any of the out-of-home alternatives. Part 2 describes the project's background and design. Part 3 presents the survey results. Clusters, based on need factors, differentiated among the costs of services: need for environmental service, need for personal service, and need for professional service. Cluster 1 specifies professional treatment, Cluster 2 requires personal service only, and Cluster 3 requires environmental services only. A chart illustrates the comparisons between the three clusters and appropriate service delivery alternatives. Cost analyses are conducted in terms of the factors. A 10-page annotated bibliography, a 4-page supplementary bibliography, and a list of addresses of sources are included. (JB)
