Included: all patients who were seen by a stroke consultant within 72h of clock start.
| Excluded: patients who were not seen by a stroke consultant within 72 hours of clock start are excluded from this indicator |
For patients newly arriving at hospital, the time between clock start and being assessed by a stroke consultant is the difference between the date and time of arrival (Q 1.13) and the date and time of assessment by stroke consultant (Q 3.3).
For patients already in hospital at the time of their stroke (Q 1.10 is ‘Yes’), the time between clock start and being assessed by a stroke consultant is the difference between the date and time of symptom onset (Q 1.11) and the date and time of assessment by stroke consultant (Q 3.3).
Cohort median: To find the median time, all the times between clock start and assessment by stroke consultant need to be listed from smallest to largest. The median is then the number in the middle of this list.
Please note: From Dec 2017-Mar 2018 questions were added to the dataset and therefore the times used to calculate this Key Indicator are: for patients whose first contact (Q3.3b) is “In person” or “Telemedicine”, the time contact first made with a stroke specialist consultant is used (Q3.3a), and for patients whose first contact (Q3.3b) is “By telephone”, the time first assessed by stroke specialist consultant in person (Q3.3c) is used.

Example
Patient A arrived (clock start) at hospital at 12:57 on Tuesday. They were assessed by a stroke consultant at 15:18 that same day. Patient A’s time from clock start to being assessed by a stroke consultant was 2:21.
Patient B arrived (clock start) at hospital at 09:15 on Friday. They were assessed by a stroke consultant at 19:16 that same day. Patient B’s time from clock start to being assessed by a stroke consultant was 10:01.
Patient C arrived (clock start) at hospital at 13:08 on Sunday. They were not assessed by a stroke consultant so are excluded.
Patient D had an onset in hospital (clock start) at 22:00 on Friday. They were assessed by a stroke consultant at 09:38 the following Monday. Patient D’s time from clock start to being assessed by a stroke consultant was 59:38.
Patient E arrived (clock start) at hospital at 03:15 on Monday. They were assessed by a stroke consultant at 11:47 on Tuesday. Patient E’s time from clock start to being assessed by a stroke consultant was 20:32.
Patient F arrived (clock start) at hospital at 23:33 on Wednesday. They were assessed by a stroke consultant at 11:03 on Saturday. Patient F’s time from clock start to being assessed by a stroke consultant was 59:30.
Listing in numerical order: 2:21 10:01 
The cohort median is 20 hours 32 minutes.
