Numerator = the number of patients who were assessed by a stroke specialist consultant physician within 24h of clock start.
Denominator = all the patients in the cohort. Patients who are not assessed by a stroke consultant are included in the denominator.
To calculate whether a patient is included in the numerator:
For newly arrived patients, the difference between the date and time of assessment by stroke consultant (Q 3.3) and date and time of arrival (Q 1.13) must be greater than or equal to 0 minutes and less than or equal to 1440 minutes.
For patients already in hospital stroke (Q 1.10 is ‘Yes’), the difference between the date and time of assessment by stroke consultant (Q 3.3) and the date and time of symptom onset (Q 1.11) must be greater or equal to 0 minutes and less than or equal to 1440 minutes.
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 X arrived (clock start) at hospital at 15:00 on Tuesday. They were assessed by a stroke specialist consultant at 10:00 the following day. Patient X has achieved the indicator because 10:00 Wednesday – 15:00 Tuesday = 1140 minutes (19 hours).
Patient Y arrived (clock start) at hospital at 12:15 on Saturday. They were assessed by a stroke specialist consultant at 11:15 the following Monday. Patient Y has not achieved the indicator because 11:15 Monday – 12:15 Saturday = 2820 minutes (47 hours).
Patient Z arrived (clock start) at hospital at 20:08 on Thursday. They were not assessed by a stroke specialist consultant so have not achieved the indicator.
Therefore the cohort percentage is 0.33 or 33% or
