The project addresses problems associated with usage and cost of disposable medical supplies on a nursing line. As hospitals look for methods to reduce costs without cutting performance or patient satisfaction, supply line inefficiencies are coming under heavy scrutiny. Working with representatives from a non-profit group, Eastern Connecticut Health Network, a major supply problem was identified and a system dynamics model was created in Vensim for a particular nursing line. The resultant model indicates that a lack of observable feedback and response has placed ECHN in a position where uncharged disposable medical supplies increase costs. It was concluded that based on current conditions, increasing disposable medical supply value awareness would create a net savings for the hospital.
