To the Editor: Thrombolytic therapy improves outcomes after ischemic stroke, but most patients are ineligible because they do not present in time.1 This has prompted efforts to educate people to call 911 for signs of stroke because ambulance transportation results in faster arrival at the emergency department (ED).2 Regional studies have suggested suboptimal ambulance use among patients with stroke,3 but none has examined a nationally representative population or temporal trends since the approval of thrombolysis.
