Rising long-term care cost due to increase in senior population is a serious issue that concerns many public policy makers in the U.S. States come up with different policies to tackle the problem, and one of the policies that recently gained much support is a single point of entry system. The single point of entry is a place where people visit, have their needs assessed, and obtain information about different long term care service options. The supporters argue that by implementing the single point of entry, it is possible to reduce long term care cost by directing many potential institutional care recipients to better fitted home and community based care. This paper is about a system dynamics model built for a government agency that is about to propose the policy to key decision makers. The modeling process and insights gained from the model will be discussed in this paper.
