Numerator = the number of patients who were assessed by a nurse trained in stroke management within 24h of clock start.
Denominator = all the patients in the cohort. Patients who are not assessed by a nurse trained in stroke management 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 nurse (Q 3.2) 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 at the time of their stroke (Q 1.10 is ‘Yes’), the difference between the date and time of assessment by stroke nurse (Q 3.2) 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.
Cohort percentage:

Example
Patient X arrived (clock start) at hospital at 15:00 on Tuesday. They were assessed by a stroke nurse 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 nurse 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 nurse so have not achieved the indicator.
Therefore the cohort percentage is 0.33 or 33% or
