Emergency medical services interval and mortality in significant head injury: a retrospective cohort study

摘要

Objectives Recent interest has focused on reorganizing emergency medical services (EMS) for English traumatic brain injury (TBI) patients, with bypass of nonspecialist hospitals and direct transportation to distant neuroscience centres. This may expedite specialist neurocritical care and neurosurgical interventions, but risks harms from prehospital deterioration and delayed resuscitation. We therefore aimed to investigate the effect of EMS interval on outcome following head injury.
