Included: all patients who were thrombolysed are included in this indicator.
| Excluded: all patients who were not thrombolysed are excluded from this indicator |
For patients newly arriving at hospital, the time between clock start and thrombolysis is the difference between the date and time of arrival (Q 1.13) and the date and time patient was thrombolysed (Q 2.7).
For patients already in hospital at the time of their stroke (Q 1.10 is ‘Yes’), the time between clock start and thrombolysis is the difference between the date and time of symptom onset (Q 1.11) and the date and time patient was thrombolysed (Q 2.7).
Cohort median: To find the median time, all the times between clock start and thrombolysis 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 thrombolysed at 13:18 that same day. Patient A’s time from clock start to thrombolysis was 0:21.
Patient B arrived (clock start) at hospital at 09:15 on Friday. They were thrombolysed at 10:16 that same day. Patient B’s time from clock start to thrombolysis was 1:01.
Patient C arrived (clock start) at hospital at 13:08 on Sunday. They were not thrombolysed so are excluded.
Patient D arrived (clock start) at hospital at 07:00 on Friday. They were thrombolysed at 07:38 that same day. Patient D’s time from clock start to thrombolysis was 0:38.
Patient E arrived (clock start) at hospital at 03:15 on Monday. They were thrombolysed at 04:47 that same day. Patient E’s time from clock start to thrombolysis was 1:32.
Patient F arrived (clock start) at hospital at 23:33 on Friday. They were thrombolysed at 00:03 on Saturday. Patient F’s time from clock start to thrombolysis was 0:30.

The cohort median is 0 hour 38 minutes.
