Short intervals between stroke onset and thrombolysis determine the efficacy of this procedure. Guidelines for stroke management were introduced in 2005 in the West-Tallinn Stroke Centre and in 2008 in the Tallinn Emergency Medical Services. Since 2006, annual joint stroke meetings of pre- and in-hospital staff have been held. These meetings included analysis of time delays of thrombolyzed patients.

The aim of the study was to analyze changes in time delays in acute stroke management and adherence to treatment guidelines.

Pre- and in-hospital data of all consecutive ischemic stroke patients who received intravenous thrombolytic therapy were recorded prospectively at the Stroke Centre. Data from the implementation period of thrombolysis (2005–2008 i.e., 1st period) were compared to recent data from 2009 to 01 September 2010 (2nd period). The data from all stroke patients presenting to ambulance services were analyzed separately from 01 September 2009 to 01 September 2010. Recorded procedures were compared to current treatment guidelines.

A total of 115 patients received thrombolysis at the Stroke Centre. The Alarm Centre assigned the correct priority (C, lights and sirens) for 31% of thrombolyzed patients during the 1st period, and for 80% during the 2nd period. The mean time ambulance personnel spent at the home was 20 minutes during both periods. In-hospital door-to-needle time was < 60 minutes in 11% of patients during the 1st period, and in 56% during the 2nd period. Ambulance personnel treated 1,094 stroke patients during the study. All procedures were performed and documented correctly in 10% of visits. The most frequent deviation from guidelines was under-reported values of blood glucose. In 44.7% of patients, an ECG was performed, which is not required by guidelines.

Acute stroke management improved significantly. Adherence to recently developed stroke guidelines in the ambulance services must be improved.
