Estimating Supplies Program: Evaluation Report

Abstract : Naval Health Research Center developed the Estimating Supplies Program (ESP) as a decision tool for medical planners, providers, logisticians, and trainers that calculates the amount of supplies required to treat a specific patient stream and assesses inventory readiness. The purpose of this document is to explain the program methodology, algorithms, and calculations that ESP uses to estimate medical supplies and evaluate inventory readiness. Sample reports for both the estimating supplies and the inventory readiness capabilities are included to provide a concrete demonstration of ESP capabilities. To demonstrate the estimating supplies capability, two different patient streams were run through the same functional area. A comparison of the supply differences was then drawn out to show an explicit connection to the difference in the patient streams. To demonstrate the inventory readiness assessment capability, an inventory was built. Certain supply item quantities were changed and a comparison was made between the S ratings, a measure calculated to indicate the percentage of supplies on hand.
