This case study, one in a series of research efforts designed to examine the utilization of the Administration on Aging's research, discusses reasons for the wide utilization of the Older Americans Resources and Services (OARS) research. (The OARS methodology assesses the levels of functioning of individual elderly persons. The resulting information may be used to determine the types of services needed by the person.) OARS is first defined, and its three characteristics--an assessment instrument, a resource allocation model, and an organizational resource at Duke University--are briefly described. The OARS research project is then summarized. Illustrative vignettes describe three types of applications of the OARS methodology: estimation of potential needs for services to elderly populations across the country, community planning, and an intake instrument to assess levels of functioning of individuals entering a specific clinic or facility. Three propositions for improving utilization are suggested: extensive social networking, interventions to boost utilization, and vigorous information dissemination. These propositions are then discussed as policy implications. (YLB)
