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. Portions of the supplies are provided by multiple vendors to a unitized container sequencing center where the supplies are bundled by care events and packed into a unitized container. This container is then shipped to a customer or distributor for further shipment to a customer.
