Avoiding in hospital delays and eliminating the three-hour effect in thrombolysis for stroke.

Abstract

Intravenous thrombolysis for acute stroke is more efficient the earlier the treatment is initiated. In-hospital delays account for a significant proportion of avoidable time loss before treatment is initiated. Paradoxically, studies have reported longer door-to-needle times the earlier the patients arrive ('three-hour effect'). Hypothesis We hypothesized that a standardized thrombolysis procedure carried out in a specialized neurological emergency room can minimize in-hospital delays and erase the 'three-hour effect'.
