Abstract: A method for integration of the institutional supply chain for medical products utilizing a nested bill of materials on a care event level of a clinical pathway for one or more medical procedures. The medical supplies appropriate for use in a care event are expressed as a bill of materials. Each item of medical supply is assigned a unique identifier which includes at least identification of the item itself, identification of the supplier of the item, and identification of the care event with which the item is to be used. At a first location a portion of the supplies are unitized and containerized. This subassembly is transported to a second and remote location where further of the supplies are unitized and containerized, using the same container. Thereafter the unitized and containerized supplies are transported to the end user thereof.
