Table 1 Time intervals and their method of calculation
From: Training emergency services’ dispatchers to recognise stroke: an interrupted time-series analysis
Time interval | Method of calculation |
|---|---|
Call to arrival at scene | Time ambulance arrived at scene minus time call made to EMS |
Call to arrival at hospital | Time ambulance arrived at hospital minus time call made to EMS; If time arrived at hospital was missing, time of admission to hospital was used instead; if both these were missing, time of triage was used. |
