PLAT and stroke disorder: Examples of process changes to be included in the simulation include: always administering tPA outside of the imaging area (10, 35–37), obtaining the patient's blood sample in parallel with other arrival activities before going to imaging, transporting the patient on the EMS stretcher to imaging (10, 11, 35, 36, 38), pre-notifying imaging technologists of an arriving stroke, and further use of parallel processing (36).
