Blood product availability in the Washington state trauma system

Early transfusion can prolong life in injured patients awaiting definitive hemorrhage control. We conducted a community resources assessment of blood product availability at hospitals within the Washington State (WA) Regional Trauma System, with the expectation that a minority of Level IV and V centers would have blood products routinely available for use in resuscitation.

We designed a questionnaire soliciting information on routinely available unit quantities of red blood cells (RBC), plasma, platelets, cryoprecipitate, and/or whole blood and submitted this questionnaire electronically to the 82 WA designated trauma centers (Levels I-V). Non-responders were contacted directly by telephone. The study was conducted in September and October 2021. US 2020 census data were used to correlate results with local population densities.

First-round contact netted responses from 57 (70%) centers; the remaining centers provided information via telephone, for a 100% final response. Packed RBC were available in 79 of the 82 centers (96%; range 6-220 units); plasma, 62 centers (76%, range 1-100 units); platelets, 40 centers (49%, range 1-8 units); cryoprecipitate, 45 centers (55%, range 1-20 units). Whole blood was only available at the Level I center. Three Level V centers, located in 2 of the 8 WA state trauma regions, reported no routine blood availability. The two trauma regions affected represent 12% of the state's population and more than a third of its geographic area.

Within the WA regional trauma system, blood products are wide, if unevenly, available. Large urban/rural disparities in availability exist that should be explored.
