The equipment and consumable supply blocks for the surgical company operating room (OR), officially known as Authorized Medical Allowance Lists 639 and 640, respectively, have not been updated since 1998. The success of the new Forward Resuscitative Surgery System (FRSS) in Operation Iraqi Freedom and the use of surgical company ORs as jump FRSSs to relieve the mobile surgical suites as they moved forward with the front line showed the need to standardize the supplies used in both ORs to minimize training and logistical support requirements. The primary objective of this study was to determine the supply requirements of the surgical company OR with equipment that has been upgraded and standardized to the level of the FRSS. The new supplies and equipment must uphold the Marine Corps doctrine of greater mobility and minimal logistical footprints on the battlefield. The NHRC method of modeling clinical requirements was chosen for this project due to its ability to provide an audit trail for each piece of equipment and each consumable supply item. The NHRC method utilizes the Deployable Medical Systems (DEPMEDS) "Time, Task, Treater" files for Levels 3 and 4, but adapted to Levels 1 and 2 of field medical care. Seventy-two DEPMEDS patient conditions (PCs) were identified for the surgical company OR level of care (Level 2), including 59 PCs also seen at the FRSS and 13 that were surgical company-specific. Equipment and consumables from both ORs were compared and, where appropriate, upgraded equipment and supplies from the FRSS were substituted for older equipment in the surgical company OR. Task profiles were then created using the DEPMEDS treatment profiles and the revised surgical company OR supplies. A patient stream was created using NHRC's Estimating Supplies Program and ReSupply Validation Program and run through the revised surgical company OR model, producing a supply list that linked each item to its PC and task.
