title: Letter.
abstract: The change in emphasis from door-to-needle to call-to-needle times (Emergency Nurse, July - August 2003) represents a more difficult challenge for emergency nurses than before. At the heart of the change is the introduction of pre-hospital administered thrombolysis. This is to be welcomed but it is in its infancy and many patients will be excluded by the initial entry requirements for ambulance service treatment.
