Predictive model for optimizing prehospital transfusions in an urban EMS system.

ABSTRACT:

Background

Prehospital transfusions might provide a survival benefit for injured patients. Because blood products are a scarce resource, their optimal deployment requires careful consideration. A computer model was built to explore different deployment scenarios for two blood-carrying ambulances (mobile blood banks, MBBs) in the City of Pittsburgh.

Study design and methods

Mixed integer programs were used to determine the optimal locations for the bases of the two MBBs from amongst the City's 14 ambulance bases. Then, a discrete-event simulation of dispatching MBBs to attend to patients who would have qualified for prehospital transfusions due to having hypotension following injury was performed using data from one year of calls to the City's emergency services hotline (911
