Included: all patients who were admitted to a stroke unit at the first hospital they were admitted to are included in this indicator.
| Excluded: patients who were not admitted to a stroke unit at the team the patient was first admitted to are excluded from this indicator |
For patients newly arriving at hospital, the time between clock start and arrival on the stoke unit is the difference between Q1.15 (date and time the patient first arrived on a stroke unit) and the data and time of arrival (Q1.13).
For patients already in hospital at the time of their stroke (Q 1.10 is ‘Yes’), the time between clock start and arrival on the stroke unit is the difference between the date and time of symptom onset (Q 1.11) and the date and time the patient first arrived on the stroke unit (Q1.15).
Cohort median: To find the median time, all the times between clock start and arrival on stroke unit need to be listed from smallest to largest. The median is then the number in the middle of this list.

Example
Patient A arrived (clock start) at hospital at 12:57 on Tuesday. They were admitted to the stroke unit at 16:18 that same day. Patient A’s time from clock start to stroke unit was 3:21.
Patient B onset in hospital (clock start) at 09:15 on Friday. They were admitted to the stroke unit at 11:16 that same day. Patient B’s time from clock start to stroke unit was 2:01.
Patient C arrived (clock start) at hospital at 13:08 on Sunday. They were not admitted to the stroke unit at this team. They stayed on a medical assessment unit (MAU). Patient C was not admitted to a stroke unit so is excluded.
Patient D arrived (clock start) at hospital at 07:00 on Friday. They were admitted to the stroke unit at 07:38 that same day. Patient D’s time from clock start to stroke unit was 0:38.
Patient E arrived (clock start) at hospital at 03:15 on Monday. They were admitted to the stroke unit at 04:47 that same day. Patient E’s time from clock start to stroke unit was 1:32.
Patient F arrived (clock start) at hospital at 16:15 on Monday. They were admitted to the stroke unit at 17:59 that same day. Patient F’s time from clock start to stroke unit was 1:44.
Listing in numerical order: 0:38 1:32 
The cohort median is 1 hour 44 minutes.
