Service time describes the efficacy of the process being measured, however, application of a ratio measure may not be applicable for assessing service time for personal protective equipment. Refer to NIOSH's PPE Burn Rate Calculator: https://www.cdc.gov/coronavirus/2019-ncov/hcp/ppe-strategy/burn-calculator.html. Through previous NIOSH funded research with C4MI, analysis algorithms were able to be developed to evaluate PPE supply and demand trends within and across nation's hospitals. Initial algorithms can be further assessed to inform utility in identifying replenished rates and warning levels broken down by manufacturer and model for PPE supply disruptions.

None

Proposed Wording:

As a measure of the efficacy of the process being measured, service time may also be determined by considering how quickly personal protective equipment is being replenished and how quickly PPE is being used. Capturing PPE backorders or delivery delays may serve as a helpful and early indicator of supply chain disruptions. Similarly, measures capturing how many gloves, gowns, respirators, and masks that are being used each day can be used with current supply data to determine if sufficient quantity is available to meet demand.
