Simulation-based team training improves door-to-needle time for intravenous thrombolysis

There is a clinical need for shortened door-to-needle time (DNT) for intravenous thrombolysis, but effective training methods are missing. Simulation training improves teamwork and logistics in numerous fields. Still, it is not clear if simulation improves logistics in stroke.

To evaluate the efficiency of a simulation training programme, the DNT of participating centres was compared with the rest of stroke centres in the Czech Republic. Patients' data were prospectively collected from the nationally used Safe Implementation of Treatments in Stroke Registry. The outcome was an improvement in DNT in 2018 as compared with 2015 (after and before the simulation training). Scenarios were based on real clinical cases, and simulation courses were conducted in a standardly equipped simulation centre.

Between 2016 and 2017, 10 courses were conducted for stroke teams from 9 of all 45 stroke centres. DNT data were available both in 2015 and 2018 from 41 (91%) stroke centres. The simulation training improved the DNT in 2018 as compared with 2015 by 30 min (95% CI 25.7 to 34.7) and as compared with 20 min (95% CI 15.8 to 24.3) in stroke centres without the simulation training (p=0.01). Any parenchymal haemorrhage occurred in 5.4% and 3.5% of patients treated in centres without and with simulation training (p=0.054), respectively.

DNT was considerably shortened nationally. It was feasible to implement simulation as a nationwide training programme. The simulation was associated with improved DNT; however, other studies should confirm that such an association is causal.
