Abstract
The walking blood bank (WBB) is a system for emergency blood acquisition from nearby donors if a patient's blood needs exceed the immediate supply. USCENTCOM medical units will perform a walking blood bank if immediate blood requirements exceed the local supply. A benchmark WBB performance time was needed to provide a training goal for military WBB exercises. An expeditionary WBB performance time benchmark was created from prospective measurements of USCENTCOM medical unit performance times over 9months. The mean total time, and new performance benchmark, for a WBB in USCENTCOM was 41.4min +/- 13.2min. USCENTCOM time from donor arrival to a transfusable unit mean time was 34.4 +/- 12.1min. Expeditionary medical units conducting a WBB should expect to meet or exceed the provided benchmark.
