Service block time allocation is a critical requirement for the optimization of patient throughput and access to care in the Surgical Services Service Line of the US Army Medical Command. The procedure complexity, volume, and diversity across 25 facilities create significant variation in service block time. This variation requires the involvement of both the informatics and leadership teams for block time allocation to be effective. This article describes our use of the Army's Surgery Scheduling System, which includes service block time as an embedded function, to develop a standardized process that helps ensure service block time is optimized. We also present guidelines for block time allocation and offer case studies that demonstrate the application of these guidelines.
