Organizational changes aiming to reduce iv tPA door-to-needle time

Objectives To assess time trends in intravenous thrombolytic (iv tPA) treatment in a general local hospital during a period with organizational changes, especially how movement of treatment start from the emergency room (ER) to the CT laboratory, and changing method of administration of acute antihypertensive medication influenced on door‐to‐needle time (DNT). Materials and methods All stroke patients treated with iv tPA have been prospectively enrolled in the Safe Implementation of Treatments in Stroke (SITS) registry. Data from 2007 to 2011 were reviewed. Safety was evaluated by the incidence of symptomatic intracerebral hemorrhage (SICH). Predictors of DNT were assessed by multivariable regression. Results Two hundred and forty‐three patients were treated with iv tPA. The annual treatment rate reached 21.9% of patients with ischemic strokes admitted to the hospital. Median DNT decreased from 36 to 28 min (P ≤ 0.001). The incidence of SICH remained low and was throughout the period 2.5%. Treatment start in the CT laboratory vs in the ER was associated with a reduction in median DNT (P = 0.007). Acute antihypertensive treatment and treatment with warfarin were associated with increased DNT (P = 0.024 and P = 0.003, respectively). Age, gender, baseline NIHSS, onset‐to‐door time, comorbidity, and method of administration of acute antihypertensive treatment did not influence DNT significantly. Conclusions Streamlining of iv tPA logistics can reduce median DNT to
